Description
Technical field
The invention belongs to fluid technique field, it is related to a kind of fluid and selects to device, conveyed especially suitable for gas or liquid
System, the case where providing fluid commonly used in two fluid source parallel connections for an equipment.
Background technique
Current certain feed flow, gas supply occasion are likely to occur the case where two fluid sources provide fluid for the same equipment,
Usual two fluid sources are relationship in parallel, only one fluid source of any time work, when selection fluid in logic in connection
When source 1, fluid source may bring damage by 2 reverse counterflow of fluid source or fluid sources 2.
Under normal conditions, to solve the problems, such as that reverse counterflow generally uses Fig. 5 scheme to realize, respectively in two fluid source ports
Place's installation check-valves, when fluid source 1 is run, corresponding check-valves is opened, and fluid can be normal through since fluid source 1 be run
When, acting in opposition is generated to the check-valves in right branch, check-valves is in close state, and fluid can not pass through, and avoid fluid
Reversely.The shape body that check-valves opens and closes works as flow direction as shown in figure 4, Wafer Check Valves is made of valve body and piston
When identical as actual requirement, block is moved up, and occurs gap around block and valve body, and fluid is flowed through from gap site.It can from Fig. 5
To find out, Wafer Check Valves inlet fluid area is circle, and internal circulation area is annular, and circulation area substantially reduces, draws
It plays flow velocity to become larger, causes fluid oscillation and empty song.
The choosing realizes fluid automatic reverse by the sliding of internal piston to device, in import and outlet stream path
Area does not mutate, substantially identical as main pipeline circulation area, therefore automatic selection valve will not cause additional fluid oscillation.
Summary of the invention

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
Shown in referring to Fig.1, a kind of fluid disclosed by the invention is selected to device, whole T-shaped, point left import and right import,
Intermediate one is outlet, and inlet and outlet are connect with external pipe, can only have an entrance to have fluid entrance, including cylinder in any case
Body 1 and the outlet end 5 among cylinder 1,1 two sides of cylinder are respectively provided with 3 He of left input end of connection external pipe
Right input end 4 is placed with piston 2 in the cylinder 1, and the left input end 3 and right input end 4 are respectively arranged with end method
Orchid 6, end flange 6 and 1 outer wall of cylinder weld, and are equipped with closure plate flange 8 outside end flange 6, the inner hole of closure plate flange 8 is less than
Sealing surface is formed on the inside of 2 outer diameter of piston, 2 end face of piston and closure plate flange 8.
The present invention uses Standard fittings as choosing to device cylinder 1, and installation piston 2 is used to change fluid stream inside cylinder 1
Can be formed and be sealed with 2 end face of piston to, both ends closure plate flange 8, fluid be prevented to be redirected back into, realize fluid select automatically to.Stream
Body is selected to device and is formed using Standard fittings by machining and welding, and when use only needs to weld inlet and outlet and pipeline
, as shown in Fig. 2, being provided with gasket seal 7 between closure plate flange 8 and end flange 6, and tight by washer 9 and screw 10
It is solidly connected.
When apparatus of the present invention work, as shown in figure 3, piston is shifted in the flowing of fluid onto when needing left side fluid to be passed through
On the right side of cylinder, sealing surface is formed with right side, prevents fluid from entering right side pipeline；As shown in figure 4, when needing right side fluid to be passed through
When, piston shifts cylinder left end by fluid, forms sealing surface with left side, prevents fluid from entering left side pipeline.
Fig. 5 is to be selected using the fluid that conventional check valves are realized to scheme, and Fig. 6 is that the fluid realized using apparatus of the present invention is selected
To scheme, Fig. 7 and Fig. 8 be conventional check valves fluid it is reverse/forward flow when working condition；Fig. 9 is to use conventional check valves
When work in valve body circulation area variation.By comparing it can be seen that: when fluid source operation, it is most right that piston 2 is pushed to cylinder 1
End prevents fluid from entering fluid source 2 with right end closure plate flange contact, avoids fluid by 2 reverse counterflow of fluid source or to fluid
Source 2 damages, and equally, when fluid source 2 is run, piston is pushed to cylinder left end, with left end closure plate flange contact, prevents
Fluid enters fluid source 1, and fluid is avoided to damage by 1 reverse counterflow of fluid source or fluid sources 1.
Further, the piston 2 is equipped with the type groove that outer diameter is less than 1 internal diameter of cylinder.The lateral section of piston 2 so is just in
I-shaped, I-shaped structure can reduce the contact area of piston 2 Yu 1 inner wall of cylinder, slide more smooth, described left import
End 3, right input end 4 and outlet end 5 are respectively adopted to be formed by mach Standard fittings and the welding of cylinder 1.
The standard pipe that latus rectum is DN100 may be selected in cylinder 1 of the invention, and poly- four that diameter is Φ 100 are placed in cylinder
Vinyl fluoride pole processes polytetrafluoroethylene (PTFE) pole section for the contact area for reducing polytetrafluoroethylene (PTFE) pole and cylinder inboard wall
At I-shaped, only pole both ends are contacted with cylinder inboard wall.End flange and DN100 pipeline outer wall weld, right after the completion of welding
DN100 inner wall of the pipe is handled, it is ensured that teflon rod can be free to slide in cylinder.Closure plate flange inner diameter is DN80,
When the piston that diameter is DN100 slides into the closure plate flange that internal diameter is DN80, sealing surface can be formed with closure plate flange, prevented
Fluid countercurrent current.Closure plate flange is connected by M12 screw with the internal screw thread in end flange, is put between closure plate flange and end flange
Set gasket seal.
Only need structure as shown in Figure 6 to select fluid to be mounted in pipeline to device, when fluid source 1 is opened, select to
Piston in device Slideslip to the right, prevents fluid from right side countercurrent.When fluid source 2 is opened, select piston into device to
Left slide prevents fluid from left side adverse current.
It, can be to work by disassembly any end closure plate flange if piston is selected into device to occur wearing or Caton situation
Plug is repaired or replaced.
Present invention optimizes the designs of pipe-line system structure, reduce the vibration noise of pipe-line system, improve pipe-line system
Reliability and maintainability, have better adaptability, have important economic benefit and social benefit.
The configuration of the present invention is simple, it is easy to accomplish, it is cheap；Requirements of installation space is small, simplifies pipeline configuration layout；Subtract
Lack pipeline joint face, improves the reliability of pipeline；Internal circulation area is uniform, reduces pipe vibration noise
In short, it is exactly to solve two fluid sources that fluid described in the invention, which is selected to device, compared with traditional check-valves
Parallel connection leads to the problem of reverse counterflow, while solving the problems, such as the vibration noise of pipeline.
The present invention optimizes the design of pipe-line system structure, improves the reliability and maintainability of pipe-line system, has preferably
Adaptability has important economic benefit and social benefit.
The above-described embodiments merely illustrate the principles and effects of the present invention, and the embodiment that part uses, for
For those skilled in the art, without departing from the concept of the premise of the invention, can also make it is several deformation and
