The technical field to which the invention relates.

The present invention generally relates to pressure regulators, and in particular thermostats pressure.

The level of technology

In many systems, management processes apply pressure to the working fluid of this process. Usually lowering the pressure regulators are working so that arriving on their inputs fluid under high pressure will be on the output relative to a lower regulated pressure. In this way, despite formed in it a pressure drop, reducing the pressure regulator can provide a relatively constant output pressure of the fluid for a wide range of output loads (i.e., requirements to the characteristics of the flow, capacity, and so on).

thermostat pressure is a step-down pressure regulator, which regulates the temperature of the working fluid (for example, maintains the temperature of the working fluid of the process at a given level). Control of the temperature of the working fluid process prevents condensation and/or promotes the evaporation of the working fluid in the pressure regulator as reducing the pressure of this fluid between the input and output of the controller.

Temperature controllers pressure are often used in systems sampling t is a bunch of environment. thermostat pressure you can apply for pre-heating liquids, to prevent condensation of gases or for the evaporation of liquids prior to analysis (e.g., chromatographic analysis). For example, the temperature regulator pressure can be used for heating (for example, using a source of heat) supplied to the working fluid containing the liquid that you want to analyze (for example, a liquid containing hydrocarbons). Or the controller can be used for evaporation (for example, using a source of heat) flowing the working fluid medium containing pairs that you want to analyze (for example, a vapor containing hydrocarbons).

Disclosure of inventions

In one example variant of thermostat pressure includes a housing regulator having an input connected to the first flow channel output. The heating unit is located inside the body of the regulator and covers at least part of the first flow passage. The heating unit is used to supply heat to the working fluid by passing the working fluid through the heating unit according to the first flow channel, which separates the working fluid medium from the heating unit.

In another example, the heating unit designed for use with pressure regulator includes a housing that at least partially located inside the pressure regulator. This case contains the first set of apertures for receiving the first flow channel, which separates the working fluid medium from the housing. The housing is adapted to receive source is eplate, feed heat to the working fluid through the housing in the process of passing the working fluid through the first set of apertures in the first flow channel.

As another example, the controller pressure includes means for heating the working fluid passing through the pressure regulator, and means for passing fluid from input to output of the pressure regulator. This means for the passage of fluid separates the working fluid medium from the means for heating. This means for passing a fluid medium at least partially passes through the means for heating on the path between input and output.

The implementation of the invention

In a typical case, lowering thermostats pressure to control the temperature of the working fluid using heat steam or electricity. The working fluid is heated in the controller, because with the passage of working fluid through the regulator (for example, through the valve seat), its pressure falls significantly. The pressure drop of the working fluid, according to the Joule-Thomson leads to a significant loss of heat (for example, to the temperature drop in the working fluid (e.g. gas). thermostat heats to the point the pressure drop to increase or maintain the temperature of the working is of Echuca environment, thereby preventing condensation of the working fluid when the pressure of the working fluid in the process of its passing through the regulator. In other cases, for example, may be required to vaporize the liquid. In this case, the controller takes the heat for evaporation of a liquid by passing the liquid through the regulator, which is necessary, for example, for analysis of this fluid in its vapor samples.

Figure 1 shows the known existing variant of the reduction temperature regulator pressure 100 used to control the output temperature (set temperature) of the working fluid passing through the regulator 100. The controller 100 includes a housing 102 having an inlet 104 and outlet 106. The membrane 108 and the body of the flow control 110 (for example, the shutter valve), located inside the housing 102, forming the inlet chamber 112 and the pressure chamber 114. The membrane 108 moves the body of the flow control 110 relative to the socket valve 116 to control the pressure of the working fluid at the outlet 106. The first flow passage 118 connects in fluid input 104 from the inlet chamber 112 and the second flow channel 120 connects in fluid outlet 106 with the pressure chamber 114. A circular-shaped housing 122 is connected (for example, a threaded connection with the housing 102 of the controller 100, forming a heating chamber 124. Heating to the measure 124 covers, at least part of the first and second flow channels 118 and 120. Environment 126, for example glycerol (for example, glycerol bath), is fed into the heating chamber 124 through the opening 128. The heater 130 (for example, the cartridge heater) fitted inside the chamber 124 to heat the glycerin. The control unit 132 (e.g., the electric control unit) is often used to ensure operation of the heater 130, which heats the glycerol, with the aim, for example, temperature control of the working fluid at the outlet 106. With increasing temperature of the glycerin energy (e.g. thermal energy, heat) from glycerol is transferred to the working fluid through the sections of the first and second flow channels 118 and 120, which are glycerol or immersed in it. As a result, in some cases, the increased heat causes the evaporation of the working fluid or, in other cases, prevents the condensation of the working fluid, for example, if the working fluid is in a gaseous or vaporous state.

However, in the current regulator 100 of figure 1 on Wednesday 126 (e.g., glycerin) may be imposed limit on the quantity of heat which it can pass to the working fluid. In particular, for example, the temperature of the glycerol can be restricted to a maximum value (for example, 400F), which in some is, some cases may not be sufficient for evaporation of the working fluid or prevent condensation. In addition, the glycerol in the typical case, inconvenience in handling it and expands when heated, and therefore requires space for expansion in the chamber 124. As a result, reducing the number of environments (e.g., glycerol) in the heating chamber 124 will often lead to reduced or decrease the heat transfer rate. In addition, the heated medium 126 is in contact with the surfaces 134 (for example, with the internal walls of the cylindrical body 122, thereby increasing the temperature of the outer surface of the housing 122. This configuration limits the maximum temperature of the medium (e.g., glycerol), as may be necessary so that the temperature of the outer surface of the housing 122 remained below a certain value (for example, below 275F) according to the requirements of industrial certifications or standards (e.g., standards CSA, European certificate of conformity).

In other known examples, the source of heat (for example, the cartridge heater) is located inside the working fluid. Therefore, the working fluid passing through the regulator is in direct contact with the source of heat. However, this configuration provides a low intensity of heat transfer, because the fluid is in contact with the source of heat in a short period of time when PR is walking her through the regulator, resulting in lower output temperature of the working fluid. In addition, the disadvantage of this configuration is that in the process of working portion of the working fluid is accumulated or deposited (for example, consueta) on the source of heat, resulting in increased maintenance costs, as well as cleaning or replacement of the source of warmth.

In other known embodiments, between the source of heat and the working environment have a mesh filter for filtering the working environment to prevent the accumulation of sediment (e.g., carbon deposits) on the source of heat. However, this configuration may lead to clogging of the filter (for example, due to the accumulation of sediment), which requires additional maintenance operations (for example, for replacement or cleaning of the filter). In other known embodiments, the source of heat connected to the housing proximal to the working fluid. Heat source supplies heat to the body of the regulator, which, in turn, transfers heat to the working fluid as it passes between the inlet and outlet of the housing of the regulator. In this configuration, the heat source heats the body of the regulator, which is a channel for passage of the working fluid. However, the disadvantage of this configuration may be weak heat transfer (for example, low intense the efficiency of heat transfer), therefore will require more energy to heat the working fluid to the desired temperature and maintain this temperature. In some cases, insufficient heat transfer can lead to condensation of the working fluid. In addition, the heating body of the regulator increases the temperature of the outer surface of the body of the regulator, which may limit the maximum temperature of heating of the working fluid to meet the certification standards (for example, international standards CSA).

Presented here are step-down controllers pressure reduce the pressure of the working fluid, simultaneously adjusting the temperature of the working fluid (for example, corrosive fluid, natural gas etc). For example, when used in the petrochemical industry represented here by lowering thermostats pressure support gaseous sample of the working fluid (for example, containing hydrocarbons in the vapor phase, which is necessary for analysis. In addition, represented here by lowering thermostats pressure to separate, divide or physically isolate the working fluid medium from the heating unit and/or source of heat to prevent or substantially reduce the accumulation of sediment on the source of heat and/or heating BL is ke due to condensation (for example, coking) of the working fluid.

Presented here is a step-down regulator pressure contains a heater or heating block located inside the housing of the regulator. The configuration of the heating unit allows you to place the source of heat (for example, the cartridge heater) and at least part of the flow channel (e.g., pipeline), which runs the working fluid between the inlet and outlet of the housing of the regulator. Moreover, the flow channel separates, divides, or physically isolates the working fluid medium from the heating block (and from the source of heat). The result presented here lowering thermostats pressure provide a relatively high intensity of heat transfer, which, in turn, gives significantly higher values of the output temperature of the working fluid. In addition, the cartridge heater can be in thermal relation is isolated from the casing of the regulator, what else improves heat transfer. For example, as described here regulators can provide an output temperature of the working fluid to 300F in a relatively short period of time (for example, for 650 seconds). In contrast, many known thermostats pressure in a typical case can provide output values of the working temperature is only environments up to 200F. Thus, the presented here options of regulators can submit working fluid environment with significantly higher output temperatures than many known regulators.

In addition to or as an alternative, it should be noted that the presented here options of regulators can contain a source of heat in a pure state (for example, does not contain sediment accumulation due to coking). In addition, the heating unit capable of providing a significantly higher maximum temperature than, for example, glycerin, allowing presented to the regulators feeding the working fluid environment (e.g., a sample) from a larger or more high temperature. Moreover, the presented here options of regulators can maintain the temperature of the outer surface (for example, the outer surface of the hull below the desired set temperature (for example, below 275F) to meet the requirements of the certification standards (e.g., standards CSA, European certificate of conformity and the like), while providing a significantly higher temperature of the working fluid at the output of the regulator (i.e. the output temperature).

Figure 2 illustrates a variant of the reduction thermostat pressure of 200. The controller 200 includes a housing regulator 202 is associated (for example, the screw connection) with a heating chamber 204. In this embodiment, the heating chamber 204 represents the body of the cylindrical associated threaded connection with the housing 202. The body controller 202 is connected with the input connector 206 for connection to fluid regulator 200 to the upstream pressure source and to the output connector 208 for connection to fluid regulator 200 with a downstream device or system. For example, the input connector 206 connects the controller 200, for example, to the process control system, the feed to the controller 200, the working fluid environment (e.g., containing hydrocarbons under relatively high pressure (e.g., 4500 psig). Output connector 208 connects in fluid regulator 200, for example, located downstream system, such as, for example, sampling for which you want to submit the working fluid medium under certain (e.g., lower) pressure (e.g., 0-500 psig). System sampling may contain analyzer (e.g., gas analyzer), which may require working fluid was supplied under a relatively low pressure (e.g., 0-500 psig), while the temperature of the working fluid (for example, 30F) forced her to remain in a vapor state, necessary to perform the analysis of the working fluid (e.g., for quality control). The housing 202 may also contain holes 210 and 211 for connecting, for example, pressure gauges (not shown), flow meters (not shown), etc.

The control unit 212 operatively connected to the housing of the controller 202, and supplies power to the source of heat or element (not shown)located inside the heating chamber 204. In addition, the control unit 212 may include a temperature sensor such as a thermocouple, a thermistor and the like, operatively associated with the housing of the regulator (for example, located close to the flow channel between the inlet and outlet, inside of the flow channel, and the like) and responsive to the temperature of the working fluid. This temperature sensor, in turn, sends a signal (e.g., electrical signal) to the control unit 212. The control unit 212 may be configured to compare the measured temperature of the working fluid (e.g., received from a temperature sensor) with the desired or predetermined temperature, and on the basis of a difference between the measured temperature (for example, 150F) and a set temperature (for example, 300F) driving electric current of the heating element. Thus, for example, the control unit 212 can perform thermostatic control source of heat or item (n is an example, the heating element). In some embodiments, the control unit 212 may include a display 214 (e.g., LCD screen), showing, for example, the measured temperature of the working fluid at the outlet 208, the temperature of the source of heat or any other characteristic of the working fluid (for example, the output pressure and the like).

On Figa and 3B are presented in terms of the kinds of the reduction temperature regulator pressure 200 of figure 2. In this embodiment, the housing 202 includes upper housing 302 that is associated (for example, a threaded connection with the lower part of the body 304. The membrane 306 is enclosed between the upper housing 302 and the lower housing 304. The upper housing 302 and the first side 308 of the membrane 306 form the first chamber 310. Bias element 312 (e.g., a spring) is located inside the first chamber 310 between the adjusting slot of the spring 314 and the membrane plate 316, which supports the membrane 306. In this embodiment, the first chamber 310 communicates via a fluid, for example, with the atmosphere through a vent hole 318. Controller force of the spring 320 (e.g., screw) acts on the adjusting slot of the spring 314, allowing you to adjust the length of the bias element 312 (e.g., increasing or decreasing the compression of the bias element 312), and hence to regulate (e.g., increase or decrease) the value of the given force or load, which is amausi element 312 is applied to the first side 308 of the membrane 306.

The lower housing 304 and the second side 322 of the membrane 306 at least partially form a pressure chamber 324, entry 326 (for example, to connect input connector 206) and exit 328 (for example, to connect the output connector 208). The shutter valve 330 is located in the longitudinal channel or in the input chamber 332 in the lower housing 304. The socket valve 334 is located between the input chamber 332 and the pressure chamber 334 and forms a hole 336 in the path of the fluid between the inlet 326 and output 328. In this embodiment, the valve seat 334 is pressed against the flange 338 formed, for example, by tankowanie. The shutter valve 330 operatively associated with the membrane 306 through the membrane plate 316 and the valve stem 340. During operation, the membrane 306 moves the shutter valve 330 to the nest valve 334 or away from it, thereby blocking or passing a flow of fluid between the inlet 326 and output 328. The second spring 342 is located inside the entrance chamber 332 and pressed the shutter valve 330 to the nest valve 334. In the present embodiment, the shutter valve 330 may stick to the slot valve 334, forming a tight connection, blocking the flow of fluid between the inlet 326 and output 328. The stiffness coefficient of the second spring 342 typically significantly less stiffness coefficient bias element 312.

As shown in Figa and 3B, the inlet 36 is connected by fluid from the input chamber 332 through the first flow channel 344, and the output 328 is connected by fluid from the pressure chamber 324 through the second flow passage 346. In this embodiment, the first flow channel 344 includes an integral flow channels 348 and 350 formed in the housing of the controller 202 as a unit, and plug-plug connection of the tubular flow channel 352 (e.g., pipeline), which connects in fluid integral bypass channels 348 and 350 between the input 326 and an input chamber 332. Similarly, the second flow passage 346 includes an integral flow channels 354 and 356 formed in the housing of the controller 202 as a unit, and plug-plug connection of the tubular flow passage 358 (e.g. pipeline)connecting in fluid integral flow channels 354 and 356 between the pressure chamber 324 and the output 328. Tubular flow channels 352 and 358 are connected to the body controller 202 (e.g., to the corresponding integral flow channels 348, 350, 354 and 356) by means of fasteners 360, such as, for example, crimp fittings. However, in other embodiments, the connection between the input 326 and output 328 may be implemented using other acceptable flow channels and/or overflow channels. In the present embodiment, the tubular flow channels 352 and 358 are a pipeline made of corrosion-grin and what about the material, for example stainless steel. However, in other embodiments, the tubular flow channels 352 and/or 358 may be made of any acceptable material (materials).

Heater or heating block 362 is located at least partially within the heating chamber 204. In this embodiment, at least part of the first flow passage 344 (e.g., tubular flow channel 352) and part of the second flow passage 346 (e.g., tubular flow passage 358) is located within the heating block 362. However, in other embodiments, at least a portion of the first flow passage 344 or (as an alternative), at least part of the second flow passage 346 may be placed in a heating block 362.

The heating element or heat source 364 (e.g., cartridge heater), at least partially connected to the heating unit 362. The first and second flow channels 344 and 346 of the separated share or physically isolate the working fluid medium from the heating block 362 and/or source of warmth 364. Accordingly, the step-down regulator pressure 200 eliminates or significantly reduces the accumulation of sediment on the heating block 362 and/or the source of warmth 364 due to, for example, coking, thereby contributing to the maintenance (e.g. cleaning) regulate the and 200. As noted above, the control unit 212 (2) provides power (e.g., electric current) source of warmth 364 applying heat to the heating block 362. The heating chamber 204 includes port 366 to connect (for example, a threaded connection) of the connecting element 368 connecting the control unit and/or heat source 364 with a heating chamber 204. The connecting member 368 may be virtually isolated in thermal relation from a source of warmth 364 to improve heat transfer to the heating block 362.

In addition, the configuration or dimensions of the heating block 362 is selected such that between the outer surface 372 of the heating unit 362 and the surface 374 heating chamber 204 formed cavity 370 (e.g., an air gap or pocket). Thus, the cavity 370 (e.g., air gap) may perform the function of an insulator (for example, to provide low heat or high heat resistance), greatly reducing heat transfer between the heating block 362 and the body of the controller 202 and/or surface 374 heating chamber 204. In other words, the heating unit 362 can be heated to high temperature (for example, up to 300F to 600F)and the heating chamber 204 and/or the body controller 202 may remain relatively cool (e.g., 20F) compared to the heating unit 362. This configuration can improve the compliance of the presented controller 200 certification standards (e.g., international standards CSA) for use with volatile fluid environments (e.g., flammable or explosive environments, etc). In other embodiments, between the outer surface 372 of the heating unit 362 and the surface 374 heating chamber 204 and/or the housing of the controller 202 can be positioned insulation or other materials that prevent or significantly reduce heat transfer or increase thermal resistance. In additional embodiments, the heating chamber 204 can be isolated by vacuum from the body controller 202.

Presented in figure 2, 3A and 3B thermostat pressure 200 typically receives a working fluid medium having a high pressure inlet 326 (e.g., 4500 psig) and provides or maintains its pressure at the outlet 328 at a certain level (e.g., 0-500 psig). Set the value of the desired pressure (e.g., 500 psi) can be changed by adjusting the force applied bias element 312 to the first side 308 of the membrane 306, using knob compression spring 320. To achieve the desired output pressure of the regulator compression spring 320 rotate or rotate around the axis 376 (e.g., Ho is th clockwise or counterclockwise orientation Figa and 3B) for the purpose of adjustment efforts, applied bias element 312 to the first side 308 of the membrane 306. In turn, the force applied bias element 312 to the membrane 306, sets the shutter valve 330 in such a position relative to the valve seat 334 (e.g., delays the shutter valve 330 from valve 334 in orientation Figa and 3B), which allows the working fluid to pass between the inlet 326 and output 328. Therefore, the output or the desired pressure depends on the magnitude of a given force applied bias element 312 to installation of the membrane 306, and hence the shutter valve 330 in a desired position relative to the socket valve 334.

The pressure chamber 324 takes the pressure of the working fluid at the exit 328 through the second flow passage 346. When the pressure of the working fluid in the pressure chamber 324 increases to such an extent that its impact on the second side 322 of the membrane 306 exceeds a preset value the efforts of the bias element 312 on the first side 308 of the membrane 306, the membrane 306 is moved toward the first chamber 310 (for example, upward in the orientation Figa and 3B) against the force of the bias element 312. When the membrane 306 is moved to the first chamber 310, the membrane 306 forces the shutter 330 valve to move toward the valve seat 334, limiting the passage of fluid flow through the hole is 336. The second spring 342 pressed the shutter valve 330 to the nest valve 334 for a tight connection with the socket, the valve 334 (e.g., closed position), which allows practically to block the passage of fluid through the opening 336 (i.e. between the input chamber 332 and the high-pressure chamber 324). Blocking or substantially reduce the flow of fluid between the inlet 326 and output 328 leads to a decrease in pressure of the working fluid at the outlet 328.

Conversely, the reduced pressure of the fluid at the outlet 328 is logged in the pressure chamber 324 through the second flow passage 346. When the pressure of the working fluid in the high pressure chamber 324 falls below the set-point force applied bias element 312 to the first side 308 of the membrane 306, bias element 312 will force the membrane 306 to move in the direction (for example, downward in the orientation Figa and 3B) to the pressure chamber 324. By moving the membrane 306 to the pressure chamber 324 shutter valve 330 moves away from the valve 334, allowing fluid flow to pass through the opening 336 (for example, in the open position), thereby increasing the pressure at the outlet 328. When the output pressure is almost equal to a given value of force applied bias element 312, the membrane 306 will force the shutter valve 330 to occupy such position is the which will maintain the desired value of the output pressure and to provide the required fluid flow.

The pressure of the working fluid is significantly reduced with the passage of the working fluid through the opening 336. As a result, the pressure drop leads to a significant drop in temperature of the working fluid (for example, due to the Joule-Thomson). In order to minimize the Joule-Thomson, the working environment is heated during its passage between the inlet 326 and the output 328 of the regulator 200.

With the passage of working fluid between the inlet 326 and an input chamber 332 through the first flow channel 344 source of warmth 364 (e.g., via the control unit 212) delivers the heat to the heating block 362. In this embodiment, the heating unit 362 covers the portion of the first flow passage 344 (e.g., tubular flow channel 352). The heating unit 362 can be heated, for example, to 600F. This heat is transferred through the heating unit 362 and a tubular flow channel 352, heating the working fluid medium flowing within the tubular flow passage 352. In this way, for example, the working fluid medium can be heated as it passes through the first flow channel 344 to pass through the opening 336.

In addition, in this embodiment, the outer diameter of the tubular running the AC the Alov 352 and 358 are selected so (for example, the outer diameter is chosen relatively small), so that a significant amount of working fluid passing through the tubular flow channels 352 and 358, passed near the inner surface (e.g., inner diameter) of the tubular flow channels 352 and 358. In this way, with the passage of the working fluid near the inner surface of the tubular flow channels 352 and 358 (i.e. almost in contact with her inner surface) increases the intensity of heat transfer.

The working fluid passes between the pressure chamber 324 and the output 328 through the second flow passage 346. As noted above, the configuration of the heating unit 362 allows you to cover a portion of the second flow passage 346 (e.g., tubular flow passage 358). Heat is transferred through the heating unit 362 and a tubular flow passage 358 for heating the working fluid flowing inside the tubular flow passage 358 between the pressure chamber 324 and the output 328. In this way, for example, the working fluid environment can again be heated as it passes through the second flow passage 346. In this way, the working fluid environment containing, for example, saturated gases can be maintained in the vapor state.

Accordingly, the step-down regulator pressure 200 transmits heat to the working fluid environments is, passing through the first and second flow channels 344 and 346 (for example, at the point of pressure drop), to raise the temperature of the working fluid to the desired value (for example, 300F). Maintain the output temperature at the desired or predetermined level prevents the condensation of the working fluid or contributes to its evaporation during the pressure drop of the fluid regulator 200. In addition, the controller 200 divides, separates or physically isolates the working fluid medium from the heating block 362 and/or source of warmth 364 to greatly reduce or prevent the accumulation of carbon sediment, caused for example by coking. In addition, the gap 370 between the heating block 362 and the heating chamber 204 allows to maintain the temperature of the outer surface of the controller 200 of the following values (for example, below 275F), the desired or required to meet certification standards (e.g., international standards CSA), which allows you to use the controller 200 in working with volatile environments.

On Figa presents a top view of a variant of the heating block 362 in Figure 2, 3A and 3B. On FIGU presents a side view of a variant of the heating block 362 in Figure 2, 3A, 3B and 4A. Presented at Figo and 4B of the heating block 362 contains almost cylindrical body 402. As poisenous, section 404 of the cylindrical body 402 can be removed to reduce the overall dimensions of the heating block 362, which will allow the Assembly with the regulator 200 of figure 2, 3A and 3B. The heating unit 362 contains many holes 406a-d, the size of which is selected for reception, for example, the first flow passage 344 and/or the second flow passage 346 (Figa and 3B). In this embodiment, the heating unit 362 contains the first set of apertures 406a and 406b to receive the tubular flow channel 352 (Figa and 3B), and the second set of apertures s and 406a for receiving the tubular flow passage 358 (Figa and 3B). However, in other embodiments, the heating unit 362 may include only the first set of apertures 406a-b or the second set of apertures 406c-d for receiving the tubular flow passage 352 or tubular flow passage 358, or have any other acceptable configuration.

In this embodiment, the diameter of each hole of the many 406a-d selected almost equal to the outside diameter of the tubular flow channels 352 and 358 (for example, approximately 0.0625 inch) or more, which allows you to provide a small or tight tolerance. Thus, tight tolerance between the tubular flow channels 352, 358 and many holes 406a-d allows the outer surface of the tubular flow channels 352 and 358 practically hug the sludge is in contact with the inner surface 408 of the many holes 406a-d, thereby increasing the contact surface area, and hence the intensity of heat transfer (i.e. reducing thermal resistance between the heating block 362 and tubular flow channels 352 and 358.

In the housing 402 drilled channel 410 for accommodating a source of heat, such as a source of warmth 364 on Figa and 3B. In other embodiments, the channel 410 may be at least in part of its length threaded for connection threaded connection of the heat source and/or the coupling element (for example, the coupling element 368 on Figa and 3B).

The heating unit 362 may be made of aluminum and machined to assure tight tolerances. In other embodiments, the heating unit 362 may be made of any other appropriate material and/or corrosion-resistant materials with high thermal conductivity. In other embodiments, the tubular flow channels 352 and 358 can be molded together with the heating unit 362 or obtained through any other acceptable ways (methods) of production.

Figure 5 presents a partial view of a step-down regulator pressure 200 of figure 2, 3A and 3B. For greater clarity, the heating chamber 204 of figure 2, 3A and 3B is not shown. In this embodiment, the tubular flow channels 352 and 358 pass through the heating unit 362 in the form of letters . As shown here, the first shoulder 502 U-shaped tubular flow passage 352 is located inside the holes 406a and the second arm 504 U-shaped tubular flow passage 352 is located inside the hole 406b. Similarly, the first shoulder 506 U-shaped tubular flow passage 358 is located inside the hole C, and the second arm 508 U-shaped tubular flow passage 358 is located inside the hole 406d.

However, in other embodiments, the tubular flow channel 352 and/or the tubular flow passage 358 may be located or take place (for example, in the form of coils) through many sections of the heating unit 362, increasing the area of heat transfer. For example, tubular flow channels 352 and/or 358 can take place (for example, issuesto) through the heating unit 362 in the form of the letter W, or in any other form. This arrangement of the tubular flow passage 352 in the heating unit (for example, in the form of a letter U, the letter W and the like) increases or increases the area of heat transfer between the heating block 362 and the working fluid medium passing through the tubular flow channels 352 and 358. Increase the area of heat transfer provides greater or increased intensity of heat or low heat resistance between the heating block 362 and tubular flow channels 352 and 358, and thus ensure Ecevit increased heat transfer and/or increased efficiency in the heating of the working fluid (for example, the heated working fluid may be faster and/or working fluid may be heated to a higher desired temperature).

As shown most clearly in Figa and 3B, in this embodiment, the connecting member 360 (for example, the fitting crimp type) has a threaded edge 378 (Figa and 3B) for threaded connection to the housing of the controller 202. The second edge 380 (Figa and 3B) (e.g., a compression fitting) connects the tubular flow channel 352 and 358 to the housing of the controller 202. Such fittings crimp terminals enable respective ends 502, 504, 506, 508 U-shaped tubular flow channels 352 and 358 to pass through (for example, creeped inside) the corresponding hole of the many 406a-d heating block 362. Between the outer surfaces of the first and/or second tubular flow channels 352, 358 and corresponding holes 406a-d when connecting to the heating unit 362 can be applied epoxy 510 (e.g., thermally conductive epoxy) to seal any gaps (e.g., air pockets or gaps) between the outer surfaces of the tubular flow channels 352, 358 and the corresponding inner surfaces of the holes 406a-d heating block 362. Thermally conductive epoxy, for example, improves heat transfer (i.e. reduces the heat resistance is reduce) between the heating block 362 and the working fluid medium, passing through the tubular flow channels 352 and 358 by eliminating or substantially reducing any gaps (e.g., air gaps) between the tubular flow channels 352, 358 and corresponding holes 406a-d.

In this embodiment, the heating unit 600 contains many holes 602, the location and/or diameters of which differ depending on the location and/or diameters of the many holes 406a-d Figa and 4B. In addition, in the heating unit 600 drilled channel 604, a diameter which exceeds the diameter of the channel 410 on Figa and 4B, designed to receive a source of heat in a larger size.

7 illustrates another variant of the heating unit 700, which can be used for execution variant of the reduction temperature regulator pressure 200 of figure 2, 3A, 3B, 4A, 4B, and 5. The heating unit 700 is similar to the heating unit 362 in Figure 2, 3A, 3B, 4A, 4B and 5, as well as a variant of the heating unit 600 according to Fig.6, the difference is that the 700 block contains cutouts 702 and 704 for receiving, for example, tubular flow channels 352 and 358 on Figa and 3B. However, in other embodiments, the heating unit 700 may contain a single cutout for receiving the tubular, about the internal channel (for example, tubular flow passage 352 or - alternatively - channel 358 on Figa and 3B), or any number of cutouts. As a Supplement or alternative to, the dimensions of the cutouts 702 or 704 you can choose the appropriate for receiving U-shaped tubular flow channels, W-shaped tubular flow channels or tubular flow channels of any other shape. In the heating unit 700 drilled channel 706 for receiving a source of warmth (e.g., source of warmth 364 on Figa and 3B).

Fig illustrates another variant of the reduction temperature regulator pressure 800. Like the version of the controller 200 of figure 2, 3A, 3B, and 5 step-down controller 800 reduces the pressure of the working fluid passing through the casing 802, while controlling the temperature of the working fluid (for example, corrosive fluid, natural gas, and the like), almost similar to the above version of the controller 200. Components of the controller 800, which is almost similar or identical to the components described above, the controller 200 and performs almost similar or identical to the functions of these components, do not require repeated description. If necessary, the reader should refer to the above detailed description of the corresponding parts in figure 2, 3A, 3B and 5. For example, option d is ulator 800 Fig has a casing 802, almost like the body controller 202 (Figure 2), as well as the heating chamber 804, almost similar to the heating chamber 204 (Figure 2)presented in a variant of the controller 200 of figure 2, 3A, 3B and 5.

Instead of the heating unit (for example, the heating unit 362 for Figa, 3B, 4A, 4B and 5, the heating unit 600 for 6 or heating unit 700 to 7) in the embodiment, the controller 800 is the heating element 806, surrounds or encircles a tubular flow channels 808 and 810 (e.g., tubular flow channels, almost like tubular flow channels 352 and 358 on Figa and 3B). The heating element 806 contains insulation (not shown) to limit or prevent the availability of electrical conductivity between the heating element 806 and the tubular flow channels 808 and 810. This isolation is located between the outer surface of the tubular flow channels 808, 810 and the outer surface of the heating element 806. In this embodiment, the tubular flow channels 808 and 810 can be produced, for example, stainless steel or other metal, corrosion-resistant materials. In the process, the heating of the heating element 806 is performed by the controller (for example, the controller 212 of figure 2). The controller provides power (e.g., electric shock) heating element 806. In his ceredi, the heating element 806 delivers heat to a working fluid flowing through the tubular channels 808 and 810 for passing fluid between the inlet 812 and the output 814 of the housing of the controller 802.
