As shown in figure 1, the device 1 distribution of fluid includes a housing 3, the modules 5 of the direction of the fluid and functional elements 7 for interaction with the fluid medium. In particular, e is their elements 7 are elements for processing, and/or measurement and/or analysis of the fluid or the flow.
Building 3 is located along the longitudinal axis L and has a sectional shape essentially square. Thus, the housing 3 contains four surface 9 (2), each of which corresponds to the specified side of the square.
Each surface 9 provided with a uniform network of threaded mounting holes 11. This network meets the ANSI/IS-76.00.02-2002. The sides of the squares of the connecting axis of the holes 11 may have a length of from 1 to 37 mm, if you choose the first option of this standard.
As will be shown below, the network of holes 11 provides mounting surfaces 9 modules 5, also meet the ANSI/ISA-76.00.02-2002, i.e. modules 5, which in the top view are essentially square shape with a side length of L 38.2 mm, if you choose the first option of the standard.
Through the housing 3 passes the main channel 13 circulation of a fluid medium which is located inside the housing 3 along the axis L. In the present example, the center of the main channel 13 is essentially coincides with the center of the housing 3.
In the presented example in the main channel 13 is the filter 15, containing radial filter element 17 and two hollow tube 19. Tube 19 is inserted in the ends of the channel 13 and is provided with spacers 21. Tube 19 is compressed between them in the longitudinal direction of the filter element 17, keeping it in Adelina direction away from the side wall of the main channel 13. In another embodiment, the tube 19 may be connected with a filter element 17 by means of welding.
The first end of the housing 3 (shown in figure 1 left) continued the first flange 23 of the mounting module 5. This flange 23 is made in one piece with the housing 3.
Through the first flange 23 are four holes 25 of the supply of fluid to the modules 5. For example, these openings 25 are uniformly distributed in the angular direction around the axis L. the Holes 25 are made stepwise and contain extended parts 27 directed towards the rest of the body 3, i.e. to the right in figure 1.
In case 3 are also auxiliary channel 29 for the fluid. This channel 29 with one hand goes to the side wall of the main channel 13 in a substantially Central area of the case 3, and then passes in the longitudinal direction toward the flange 23, passes through it and exits.
The flange 23 also contains holes 31 mounting the locking plate 33 on the flange 23. These openings 31 can be distributed similarly to the holes 25 and can be located in the flange 23 at a greater radius than that of the holes 25.
Through the locking plate 33 is the Central hole 35 that communicates with the internal space of the tube 19 (figure 1 left), while the interior of this tube 19 communicates with the internal space of the filter element 17.p> Plate 33 holds the tube 19 within the channel 13.
In the side of the locking plate 33 opposite the flange 23 is made Razzakova 37, which tells the auxiliary channel 29 with holes 25 and has the shape of, for example, rings. Located one against the other sides of the flange 23 and the locking plate 33 can be installed sealing gasket 39.
All modules 5 have similar designs, so in the future with reference to figure 5 will be described in only one module.
As mentioned above, a normal module that corresponds to standard ANSI/ISA-76.00.02-2002, so its description will be brief. Module 5 is a block in the form of an essentially parallelepiped, which has essentially the shape of a square and the corners of which are equipped with sockets 41, designed for screw mounting module 5 on one surface 9 of the housing 3 by screwing into the holes 11.
In the example shown in figure 5, module 5 is made of the channel 43, which passes through a fluid medium and which itself passes through the module 5. Channel 43 extends on the top side of the module 5 through the hole 45 that is designed for power supply element 7 that is installed on the module 5 by means of four threaded holes 47 located in module 5 at the corners of the square.
As is known, the modules 5, used in the apparatus shown in figure 1, can the future shape and number of channels 43 or holes 45, different from module 5 shown in figure 5.
In the apparatus shown in figure 1, each surface 9 is equipped with modules 5, installed in a line along the longitudinal axis L. In some embodiments, the application of some surfaces 9 are not used. The communication between these different modules 5 and advanced sections 27 holes 25 of the first flange 23 is provided, as is known, the connecting elements 49, placed at the ends of the channels 43 and in sections 27.
It is also known that the elements 7 installed on modules 5.
It should be noted that figure 1 shows only some of the modules 5 and item 7.
Element 7, shown above and to the left in figure 1, may be, for example, a valve, following him to the right element 7 may be a pressure gauge, bottom left element 7 can be cleaner filter. Thus, on each surface 9 forming the circuit, all circuits allow the necessary measurements and analyses of fluid. It should be noted that in some embodiments for the connection of modules 5 that are installed on adjacent surfaces 9, and, consequently, for connections located on each side of the paths provided by curved connecting elements 63 (6).
At its second end (figure 1 right) case 3 has a second flange 51 of the mounting module 5. This flange 51 are screwed up on building the CoE 3, and as the flange 23 it contains four holes 25, ending the expanding areas 27. The flange 51 retains the right tube 19 in the main channel 13.
In sections 27 of the second flange 51 and the modules 5, the extreme right in figure 1, enter the connecting elements 49 (not shown). The connecting member 49 is located between the modules of each pair of modules 5. It should also be noted that the connecting elements 49 are located between the first flange 23 and modules 5, to the left in figure 1.
Thus, the modules 5 on the one hand fixed to the sides of a 9 by screwing into the holes 11, and on the other hand are held in the longitudinal direction through the connecting elements 49 and flanges 23 and 51.
In the present example, Razzakova 52, made approximately 180° around the axis L, connects the lower hole 25 and the two middle holes 25 of the second flange 51. Razzakova 52 made, for example, in the form of an annular sector, is closed by the shut-off plate 53 fixed to the flange 51. This plate 53 has a Central hole 35, similar to the hole 35 of the plate 33, and the two stepped holes 57 for the passage of fluid passing through the modules 5. One of these holes 57 is located opposite to the upper hole 25 and with him reported. Another hole 57 is located opposite the lower holes 25 of the flange 51 and communicates with the hole 25 and what rostenkowski 52.
The device 1, shown in figure 1, there are, for example, on otodrom circuit oil system of the engine of the vessel, for example an oil tanker.
Fluid circulating in otodrom circuit, in this case oil, is fed into the left hole 35, as shown by the arrow 59 in figure 1. Part of this fluid circulates in the longitudinal direction inside the filter element 17 and exits through another hole 35, as shown by the arrow 61, and is then forwarded to the rest of the drop path, and then into the oil system of the engine. Thus, the housing 3 forms a site run-off path.
Another part of this fluid received in the filter element 17, is filtered through the filter element 17 in the radial direction, then circulates in the auxiliary channel 29 and continues through rostenkowski 37 in the openings 25 of the flange 23. This is another part of the fluid nourishes modular series 5 installed on each surface 9. After this fluid passes through the paths formed on each of the surfaces 9 modules 5 and elements 7, which produces the necessary measurement and/or analysis.
Then fluid going from one side of the upper holes 25 of the flange 51 and the plate 53, and on the other hand - the lower and middle holes 25 of the flange 51 through razzenkovku 52 and the bottom hole 57 stratum of the us 53. The collected fluid is then sent to the idler circuit and in the oil system.
It should be noted that the upper hole 57 of the plate 53 may be designed, for example, to remove the contaminated part of the fluid medium, and in this case this part is not directed toward the discharge path or in the main channel. It should also be noted that depending on the need Razzakova 52 may, for example, to combine only two holes 25, and that can be used other Razzakova 52, and that may not be a single rostenkowski 52.
The device 1, shown in figure 1, has a very small size.
This is due to the fact that the housing 3 itself has an internal channel 13, is designed to circulate the fluid, and so that the housing 3 contains several surfaces 9 of the mounting module 5 located around the channel 13.
It should also be noted that the transit time of the fluid between the main channel 13 and elements 7 is reduced, thereby increasing the accuracy of measurements and analysis.
You can also use many other designs.
For example, figure 7 shows another variant of execution in which the device 1 is installed on the flange 65 of the outlet 67, located on the pipeline 69 industrial installations.
As shown by the arrow 71, the fluid passes through the channel 13, the e containing the filter element, and, passing upward (figure 6), is filtered in the upper filter 72, rigidly connected to the housing 3, and then goes down and passes, as shown by arrows 73, through a series of modules 5 provided along the surfaces 9 and then sent to the pipe 69. It should be noted that figure 6 to simplify the drawing, the elements 7 are not shown.
You can also use other forms of housing 3, for example with a polygonal cross-section other than square, and the housing 3 can be made of several parts.
Similarly, the number of surfaces 9 of attachment may vary and, in particular, may be less four. You can even, for example, use case 3 containing only one side 9 of the mounting modules. Indeed, the mere fact of execution in the case 3 channel 13, intended for the fluid, allows a gain in size.
On the other hand, you can use the case 3 with multiple surfaces 9, for example, each of which corresponds to the side of the polygon, not using the internal channel 13 in the housing 3.
In General, the channel 13 is not necessarily the channel intended for the passage of fluid. He may represent, for example, the channel-drive the fluid from which the fluid medium after accumulation is pushed by a piston, and then passes through a number or series of modules 5, set the run on the surface or surfaces 9 of the fastening device 1.
Holes 11 may be replaced by other fastening means, such as protrusions, and may be arranged in a uniform pattern, different from what was described above. This could be in particular the case if the above standard should be changed or must be replaced by the standard, which stipulates other requirements.
It should be noted that the casing 3, the modules 5 and the elements 7 may be sold separately.
It should also be noted that the above principles can be applied in various fields and, in particular, in industrial installations or vehicles.
