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 regulators for regulating the pressure of the working fluid in 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. Thus, in spite of the pressure drop on it step-down pressure regulator can provide a relatively constant output pressure of the fluid for a wide range of output loads (i.e. requirements specifications flow capacity and so on).

In a typical case, thermostat pressure reduces the pressure of the working fluid from inlet pressure to outlet pressure, while controlling the temperature of this fluid (e.g., maintaining 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.

In General, temperature controllers pressure control steam pressure and are often used in systems sampling, where for analyzing equipment fluid must be in the gaseous or vapor state at a relatively low pressure. For example, in the petrochemical industry for quality control are often examined (for example, by chromatographic analysis) sample of the working fluid containing liquid hydrocarbons. It is often required that such samples of the working fluid was in a gaseous state or in the vapor phase. Thus, thermostat pressure you can apply for pre-heating liquids, to prevent condensation of gases or for the evaporation of liquids prior to analysis. For example, the temperature regulator pressure can be used for pre-heating liquids, to prevent condensation of gases or for the evaporation of liquids prior to analysis (e.g., chromatographic analysis).

In the normal case, to control the temperature of the working fluid in the temperature controllers pressure applied electric or steam heating. Heat the working fluid medium in the controller because with the passage of working fluid through the regulator (for example, through the valve seat) its pressure is their significantly decreases. 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 pressure heats point the pressure drop to increase or maintain the temperature of the working fluid, thereby preventing condensation of the working fluid (for example, the saturated gas) when the pressure of the working fluid in the process of its passing through the regulator. In other cases, for example, there may be a need for evaporation of 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 the analysis of vapor samples from the liquid.

Because of the variety of applications the controller can be called a heating regulator. For example, the heating controller can be used for heating (for example, using a heating medium) of the incoming working fluid containing the fluid that is analyzed (for example, a liquid containing hydrocarbons). In another example, the controller can be used for evaporation (for example, using a source of heat) entering the working environment containing steam that you want to analyze (for example, steam, provided the hydrocarbons).

Disclosure of inventions

In one embodiment, presents thermostat pressure includes a housing having an inlet and outlet for the working fluid, interconnected through the first flow passage and the inlet and outlet for the heat transfer medium, interconnected through the second flow passage, and the inlet for the heat transfer medium is a part of the body of the regulator, constructed as a unit with the housing. The housing of the heating chamber attached detachable connection to the controller casing to form a chamber between the inlet and outlet transfer medium. At least part of the first flow passage is located inside the camera. The camera function is to receive the heat transfer medium coming from the entrance transfer medium for heating the working fluid by passing the latter through the chamber at a first flow channel, which separates the working fluid environment from teploprotsessy.

In another embodiment, the temperature regulator pressure includes a housing consisting of the upper part of the associated detachable connection with the lower part. In the lower part provides a channel for passage of working fluid between the inlet and outlet for the working fluid, and an inlet for water vapor, which is communicated with the outlet for water vapor. The housing of the heating chamber is connected with the lower part of the body of the regulator so that the existing building heating chamber cavity formed of the heating chamber as a result of this connection. Into the heating chamber via the inlet for steam is supplied water vapor. The first flow channel at least partially forms the path of the working fluid from input to output, and it is also at least partially located within the heating chamber, the first flow channel separates the working fluid environment from water vapor.

The implementation of the invention

In the presented here options of thermostats pressure applied heat transfer medium (e.g. water vapor) to control (e.g., increase) the output temperature of the working fluid (for example, corrosive fluid, natural gas, etc. in the process of reducing the pressure of the working fluid by passing it black the C controller. In particular, as described here regulators contain the input channel for the heat transfer medium, made of one piece with the housing of the regulator. Such integrated manufacturing entry transfer medium to the housing of the controller allows you to feed the controller casing heat transfer medium (e.g. water vapor) under relatively high or elevated pressure (for example, from 250 to 1000 pounds per square inch)than in the controller, whose input transfer medium or the entrance of water vapor is connected (e.g. welded connection) to the housing of the heating chamber and/or to the housing of the regulator. For example, the input transfer medium connected to the pipe or heating chamber, for example, by welding, in a typical case can take the heat transfer medium under pressures not exceeding, for example, 250 psi, as determined, for example, the ultimate strength of the welded connection.

In this way, for example by making entrance to the transfer medium as one piece with the housing of the controller), you can create a variety of temperature controllers pressure, in which a heat transfer medium will be significantly more or elevated temperature (for example, from 300 to 1000F). This configuration allows the pressure regulators with temperature control to ensure higher zacariamhoney temperature of the working fluid (for example, the output temperature of the working fluid from 300 to 1000F). Moreover, the manufacturer presented here options of regulators does not require join operations (e.g., welding) of the input transfer medium to the controller casing or housing of the heating chamber, thereby reducing the cost of production, storage, maintenance etc.

Furthermore, in the presented here options of thermostats pressure contact area of heat transfer is greater than some existing thermostats pressure. For example, at least partially, the flow-through channel (for example, a tubular flow channel) is located (e.g., twisting) inside the heating chamber in the form of coils or U-shape, which allows to increase the contact area of the heat transfer from the heat transfer medium (e.g. water vapor)in the heating chamber to the working medium passing through the flow channel. Arrangement or transaction flow passage through the heating chamber in such a way (for example, in the form of coils increases the intensity of heat transfer from the transfer medium to the working fluid passing through the flow channel, thereby providing a more or increased output temperature of the working environment.

For example, as described here regulators can provide the values of the output temperature of the working fluid, for example, approximately 500F. In contrast, existing thermostats pressure can normally give the output temperature of the working fluid at approximately 350F. Thus, the presented here options of regulators can provide significantly higher output temperature of the working fluid than some of the existing thermostats pressure.

To discuss the details presented here options of thermostat pressure should be considered an existing thermostat pressure 100 presented in figure 1. The existing thermostat pressure of 100 in the normal case, is used to control the output temperature (for example, to maintain it at a specified level 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) positioned within a 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 for regulating the pressure of the working fluid at the outlet 106. The first flow passage 118 connects in fluid entrance 104 to the input chamber 112, and the second flow channel 120 connects in fluid outlet 106 with the pressure chamber 114. The tubular body or orpus heating chamber 122 (for example, the housing has a cylindrical shape) is connected (for example, a threaded connection with the housing 102 of the controller 100, forming a heating chamber 124. The heating chamber 124 covers at least part of the first and second flow channels 118 and 120. The housing of the heating chamber 122 also contains the inlet of the transfer medium 126 and outlet 128. A heat transfer medium, for example water vapor, passes through the heating chamber 124 from the inlet 126 to the outlet 128.

In the process, the heating chamber 124 can take the water vapor, the maximum pressure value which is, for example, 250 psi, maximum temperature, such as 350F. By passing steam through the heating chamber 124 steam energy (e.g. thermal energy or heat) is transferred to the working fluid through the sections of the first and second flow channels 118 and 120 located inside the heating chamber 124. As a result, in some cases, the heat causes the working fluid environment to evaporate or, in other cases, prevents the condensation of the working fluid, for example, in the case when the fluid is already in a gaseous or vaporous state, acting in the controller 100 through the inlet 104.

However, in the current regulator 100 of figure 1 on Wednesday (the example water vapor) may be imposed limit on the quantity of heat which it can pass to the working fluid. In particular, for example, the value of the steam pressure at the inlet 126 may be restricted to a maximum value, for example, approximately 250 pounds per square inch. The limit steam pressure at the inlet 126 also limits the maximum value of the steam temperature to a value of, for example, about 350F, which in some cases will not be sufficient for evaporation of the working fluid or to prevent condensation.

Limiting the pressure transfer medium (e.g. water vapor) at the input 126 may be due to the fact that the entrance 126 in the normal case, are welded to the housing of the heating chamber 122. This weld (not shown)connecting the input of water vapor 126 with the wall 130 of the housing heating chamber 122 will not be able to withstand the vapor pressure in excess of, for example, 250 pounds per square inch. As noted above, the limitation of the steam pressure at the inlet 126 also limits the maximum temperature steam, which eventually leads to the decrease in the intensity of heat transfer between the vapor and the working fluid medium.

In addition, the welding of the inlet 126 to the wall 130 of the housing heating chamber 122 may also impose a limit on the thickness of the walls 130, for example, to the value of 1/16 inch. Stink is (for example, the wall 130) such limited thickness may not be sufficient to withstand the vapor pressure in excess of, for example, approximately 250 pounds per square inch. Thus, the existing thermostat pressure 100 will not be able to withstand the pressure transfer medium, exceeding, for example, approximately 250 pounds per square inch, which limits the temperature of the heat transfer medium in the heating chamber 124, and therefore, it is not possible to obtain a higher temperature of the working fluid at the exit. Moreover, the welding of the input port for the water vapor to the housing of the heating chamber increases the cost of production, storage, etc.

In other known cases, the steam pipe passes through the channel flow in the body of the regulator (for example, in the case of the controller 102). Therefore, the working fluid passing through the regulator is in direct contact with the steam pipe. However, this configuration in the normal case provides a lower intensity of heat transfer due to the fact that the steam pipe is in contact with the working fluid medium within a short period of time, when the working fluid passes through the regulator, and therefore the value of the output temperature of the working fluid will be lower.

In other known embodiments, the input port DL is water vapor attached to the controller casing proximal to the working fluid. In this input port receives water vapor applying heat to the body of the regulator. The body of the regulator, in turn, transfers heat to the working fluid by passing it from input to output on the controller casing proximal to the inlet port for water vapor. In this configuration, the water vapor generally heats the body of the regulator, which is the channel flow of the working fluid. However, the result of this configuration may be weak heat transfer (for example, low intensity heat), in addition, it often requires a relatively large amount of 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 Figures 2A and 2B shown in section of a variant of thermostat pressure of 200. Presented here options of thermostats pressure reduce the pressure of the working fluid, at the same time controlling the temperature of the working fluid (for example, corrosive fluid, natural gas, and so on).

Presents the controller 200 includes an upper housing 202 that is associated (for example, a threaded connection with the lower housing 204. The membrane 206 is enclosed between the upper housing 202 and lower housing 204. The upper housing 202 and the first is I side 208 of the membrane 206 to form the first chamber 210. Bias element 212 (e.g., a spring) is located inside the first chamber 210 between the adjusting slot of the spring 214 and the membrane plate 216 that supports the membrane 206. In this embodiment, the first chamber 210 communicates via a fluid, for example, with the atmosphere through a vent hole 218. The regulator spring 220 (e.g., screw) acts on the adjusting slot of the spring 214, allowing you to adjust the length of the bias element 212 (e.g., increasing or decreasing the compression of the bias element 212), and hence to regulate (e.g., increase or decrease) the value of the given force or load that bias element 212 is applied to the first side 208 of the membrane 206.

The lower housing 204 and the second side 222 of the membrane 206 at least partially form the pressure chamber 224, entry 226 and the outlet 228. The shutter valve 230 is located in the longitudinal channel or in the input chamber 232 in the lower housing 204. The socket valve 234 is located between the input chamber 232 and the pressure chamber 234 and forms a hole 236 in the path of fluid flow between the inlet 226 and the outlet 228. In this embodiment, the valve seat 234 is pressed against the flange 238 formed, for example, by tankowanie. The shutter valve 230 operatively associated with the membrane 206 through the membrane plate 216 and the valve stem 240. During operation, the membrane 206 moves satwa the valve 230 to the terminal valve 234 and from him, thereby blocking or passing a flow of fluid between the inlet 226 and the outlet 228. The second spring 242 is located inside the entrance chamber 232 and pressed the shutter valve 230 to the valve pocket 234. In the present embodiment, the shutter valve 230 may stick to the slot valve 234, forming a tight connection, blocking the flow of fluid between the inlet 226 and the outlet 228. The stiffness coefficient of the second spring 242 in the normal case, much less stiffness coefficient bias element 212.

As shown in Figa and 2B, the input 226 is connected by fluid from the input chamber 232 through the first flow passage 244, and the output 228 is connected in fluid with the high-pressure chamber 224 through the second flow channel 246. In this embodiment, the first flow channel 244 includes integral channels 248 and 250, formed in the lower housing 204 as one with him, as well as plug-plug connection of the tubular flow passage 252 (e.g., pipeline), which connects in fluid integrated channels 248 and 250 between the input 226 and the input chamber 232. Similarly, the second flow channel 246 includes integral channels 254 and 256 formed in the lower housing 204 as one with him, as well as plug-plug connection of the tubular flow channel 258 (e.g., pipeline)connecting in fluid the th environment integral channels 254 and 256 between the high pressure chamber 224 and the outlet 228. Tubular flow channels 252 and 258 are connected to the lower housing 204 (for example, to the corresponding integral channels 248, 250, 254, and 256) by means of fasteners 260, such as, for example, crimp fittings. However, in other embodiments, the connection between the input 226 and the output 228 may be implemented using other acceptable flow channels and/or overflow channels. In the present embodiment, the tubular flow channels 252 and 258 represent the pipeline, made of corrosion-resistant material, for example stainless steel. However, in other embodiments, the tubular flow channels 252 and/or 258 may be made of alloys, such as Nickel-copper, Nickel-chrome, brass, or other acceptable material (materials).

Figure 3 presents a different view in terms of the reduction thermoregulator 200 Figa and 2B. According Figa, 2B and 3, the housing of the heating chamber or tubular body 302 is connected to the lower housing 204 of the controller 200. In this embodiment, the housing of the heating chamber 302 is a circular-shaped housing, which is attached to the lower housing 204 threaded connection. When connected with the lower housing 204, the housing of the heating chamber 302 forms or forms a heating chamber 304. Input transfer medium 306 (for example, an inlet for water vapor) are made as one is integral with the lower housing 204. Integral channel 308, made of one piece with the lower housing 204, connects in fluid entrance transfer medium 306 with a heating chamber 304. From the entrance transfer medium 306 into the heating chamber 304 enters a heat transfer medium (e.g. water vapor) under a relatively high pressure (for example, from about 250 to 1000 pounds per square inch). In this embodiment, the housing of the heating chamber 302 is made of corrosion-resistant material such as stainless steel. However, in other embodiments, the tubular flow channels 252 and/or 258 may be made of alloys, such as Nickel-copper, Nickel-chrome, brass, or other acceptable material (materials).

In the present embodiment, at least part of the first flow channel 244 (e.g., tubular flow passage 252) and part of the second flow channel 246 (e.g., tubular flow channel 258) are located inside the heating chamber 304. However, in other embodiments, at least a portion of the first flow passage 244 or alternatively, at least part of the second flow channel 246 may be placed inside the heating chamber 304. In addition, the tubular flow channels 252 and 258 are positioned in the heating chamber 304 in the form of coils or U-shape, which allows to increase the contact area TopLop is passing between the heat transfer medium in the heating chamber 304 and the working fluid medium, passing through the tubular flow channels 252 and 258. Tubular flow channels 252 and 258 also performs the function of division, separation or physical isolation of the working fluid from the heating chamber 304, and hence the heat transfer from the environment. A heat transfer medium passes through the heating chamber 304 between the input transfer medium 306 and outlet for the heat transfer medium 310. In this embodiment, the outlet for the heat transfer medium 310 made of one piece with the housing of the heating chamber 302.

In the process, presents thermostat pressure 200 is connected through a fluid medium to a located upstream of the pressure source through the inlet for the working fluid 226, and through the exit 228 for the working fluid to located downstream device or system. For example, entry 226 connects the controller 200, for example, to the process control system, which feeds into the controller 200 of the working fluid (for example, containing hydrocarbons under relatively high pressure (e.g., 4500 psig). The output 228 connects in fluid regulator 200, for example, located downstream system, such as, for example, the system sampling, which requires the flow of operating fluid under a certain (e.g., reduced) pressure (e.g., 0-500 pounds is as square inch). This system sampling may contain analyzer (e.g., gas analyzer), for which you may need to submit a working fluid medium under a relatively low pressure (e.g., 0-500 psig), and also to the temperature of the fluid medium (e.g., samples) had a value (for example, approximately 500F), at which the working fluid would be in the form of vapour, which gives the opportunity to analyze the working fluid (e.g., for quality control).

thermostat pressure 200 in the normal case, regulates the pressure of the working fluid entering the input 226, providing or maintaining a certain or desired pressure at the outlet 228. Set the value of the desired pressure can be adjusted using the knob compression spring 220 by adjusting the force applied bias element 212 to the first side 208 of the membrane 206. To achieve the desired output pressure of the regulator compression spring 220 rotate or turn about the axis 312 (e.g., clockwise or counterclockwise in the orientation in Figure 3) to adjust the force applied bias element 212 to the first side 208 of the membrane 206. In turn, the force applied bias element 212 to the membrane 206, sets the shutter valve 230 in such a position relative to the saddle is lapena 234 (for example, delays the shutter valve 230 of valve 234 in orientation Figa, 2B and 3), which allows the working fluid to pass between the inlet 226 and the outlet 228. Therefore, the output or the desired pressure depends on the magnitude of a given force applied bias element 212 to the membrane 206 to install it in the desired position, and means for setting the desired position of the shutter valve 230 in relation to the socket of the valve 234.

The pressure chamber 224 takes the pressure of the working fluid at the outlet 228 through the second flow channel 246. When the pressure of the working fluid in the pressure chamber 224 increases to such an extent that its impact on the second side 222 of the membrane 206 exceeds a preset value the efforts of the bias element 212 on the first side 208 of the membrane 206, the membrane 206 is moved toward the first chamber 210 (for example, upward in the orientation Figa, 2B and 3) against the force of the bias element 212. When the membrane 206 is moved to the first chamber 210, the membrane 206 forces the shutter 230 of the valve to move toward the valve seat 234, restricting the flow of fluid through the opening 236. The second spring 242 pressed the shutter valve 230 to the terminal valve 234 for a tight connection with the socket of the valve 234 (for example, in the closed position)that can virtually block prob the discussion of fluid through the opening 236 (i.e. between the input chamber 232 and the pressure chamber 224). Blocking or substantially reduce the flow of fluid between the inlet 226 and the output 228 leads to a decrease in pressure of the working fluid at the outlet 228.

Conversely, the reduced pressure of the fluid at the outlet 228 is logged in the pressure chamber 224 through the second flow channel 246. When the pressure of the working fluid in the high pressure chamber 224 falls below the set-point force applied bias element 212 to the first side 208 of the membrane 206, bias element 212 will force the membrane 206 to move in the direction (for example, downward in the orientation Figa, 2B and 3) to the pressure chamber 224. By moving the membrane 206 to the pressure chamber 224, the gate valve 230 moves away from the valve 234, allowing fluid flow to pass through the opening 236 (for example, taking the open position), thereby increasing the pressure at the outlet 228. When the output pressure is almost equal to a given value of force applied bias element 212, the membrane 206 will force the shutter valve 230 to occupy such position that will support 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 236 In 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 226 and the output 228.

With the passage of working fluid between the inlet 226 and the input chamber 232 through the first flow channel 244 a heat transfer medium (e.g. water vapor) passes through the heating chamber 304 through the entrance to the transfer medium 306 and an outlet for the heat transfer medium 310, providing warmth of the heating chamber 304. A heat transfer medium inside the heating chamber 304 transmits heat to the working fluid flowing inside the tubular flow passage 252. In this way, for example, the working fluid medium can be heated during its passage through the first flow channel 244 to pass through the opening 236. The working fluid passes between the pressure chamber 224 and the output 228 through the second flow channel 246.

As noted above, in this embodiment, the heating chamber 304 covers at least part of the second flow channel 246 (e.g., tubular flow channel 258). The heat supplied to steam in the heating chamber 304 is passed through the tubular flow channel 258 to heat the working fluid passing through the tubular flow channel 258 between the pressure chamber 224 and the outlet 228. Therefore, working Echuca environment can again be heated as it passes through the second flow channel 246. In this way, the working fluid environment containing, for example, saturated gases can be maintained in the vapor state.

Accordingly, thermostat pressure 200 delivers the heat to the working fluid passing through the first and second flow channels 244 and 246 (for example, at the point of pressure drop) to raise the temperature of the working fluid to a specified value (for example, approximately 500F) or maintaining it at this level. 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, in this embodiment, the outer diameter of the tubular flow channels 252 and 258 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 252 and 258, took place near the inner surface (e.g., inner diameter) of the tubular flow channels 252 and 258. In this way, with the passage of the working fluid near the inner surface of the tubular flow channels 252 and 258 (i.e. almost in contact with her inner surface) increases the intensity of heat transfer.

In this embodiment, the heat transfer among the Oh is water vapor. However, in other embodiments, a heat transfer medium can be any acceptable heat transfer medium supplying heat to the working fluid passing through the regulator 200. Since the input transfer medium 306 is formed as one piece with the lower housing 204, the water vapor can flow through the input transfer medium 306 under relatively high or elevated pressure (for example, under pressure of approximately 650 pounds per square inch). For example, water vapor is supplied through the inlet for the heat transfer medium 306 under a relatively higher pressure (for example, between 250 and 1000 psig)than the water vapor pressure (for example, up to 250 psi)flowing through the inlet 126 of the controller 100 shown in figure 1. Thus, the controller 200 may receive steam or other heat transfer medium with a much higher temperature, for example, an environment with a temperature between 350 and 1000F. As a result, the controller 200 may provide a much higher temperature of the working fluid (for example, between 350 and 1000F).

In addition or alternatively, by eliminating the connecting device or welded connection between the input transfer medium 306 and the housing of the heating chamber 302 wall 314 of the housing of the heating Cham is s 302 may have an increased thickness (e.g., to % inch)that will provide increased structural strength to withstand high pressure transfer medium, for example, the water vapor pressure in the range between 250 and 1000 psig. The housing of the heating chamber 302 may be made of stainless steel or any other acceptable material (materials).

Moreover, unlike some of the existing pressure regulators pressure regulator 200 provides increased contact area of heat transfer and, consequently, increased the intensity of the heat or low heat transfer resistance between the vapor and the tubular flow channels 252 and 258. As noted above, for example, tubular flow channels 252 and 258 may be held (e.g., twisting) through the heating chamber 304 having a U-shaped, W-shaped form, the form of coils or any other form. This arrangement of the tubular flow passage 252 in the heating chamber 304 improves or increases the contact area of heat transfer between the vapor and the working fluid medium passing through the tubular flow channels 252 and 258. The increase in the contact area of the heat transfer provides enhanced or increased intensity of heat transfer between the steam and the tubular flow channels 252 and 258, and therefore enhances alopiidae and/or increased efficiency in the heating of the working fluid (for example, more rapid heating of the working fluid and/or heating of the working fluid to a higher desired temperature).
