Description
Technical field
It the utility model is related to a kind of check-valves, and in particular to check-valves is opened in a kind of piston type rotation.
Background technology
The check-valves that fluid line uses at present mainly has lift, swing type and piston type etc., but these check-valves
Leakage problem all be present in different degree.For the problem, some is stopped a leak by spring pressure, but this method
Flow resistance can undoubtedly be increased.
Utility model content
In order to overcome disadvantages mentioned above, the utility model provides a kind of piston type rotation and opens check-valves, and check-valves footpath is opened in rotation
End face soft seal is added on the basis of to sealing, up to the present this structure has not found.In order to ensure that end face is soft close
The centering of circular bulge loop is sealed, the suspended structure of bonnet assemblies is different from the suspended structure of traditional swing check valve, and it hangs
Active pin shaft can move axially, to ensure the axial movement of circular bulge loop.
The utility model is achieved using following technical scheme：
Check-valves, including housing, in addition to bonnet assemblies and suspension holdfast are opened in piston type rotation, and the housing both ends are set respectively
Inlet tube, outlet are put, is pilot hole between inlet tube and outlet；The import pipe end sets valve seat, the valve seat right side
End sets bonnet assemblies, and the bonnet assemblies have a radial sealing surfaces, and radial sealing surfaces are bonded with inlet tube terminal surface during sealing,
The valve seat opens up circular groove around inlet tube, and the circular bulge loop being engaged with circular groove, circle are set on the bonnet assemblies
Sealing ring is set in connected in star；The bonnet assemblies upper end is connected with suspension holdfast by active pin shaft, and the suspension holdfast is consolidated
It is scheduled on housing；Strip suppending hole is provided with the suspension holdfast, the active pin shaft is located in strip suppending hole and and strip
Suppending hole is vertical, and active pin shaft can move along strip suppending hole length direction, and move distance is more than circular bulge loop and enters circle
The depth of groove.
The top of the pilot hole sets mounting flange, and blind flange, the mounting flange are set above the mounting flange
Sealing gasket is set between blind flange.
Anti-reverse sliding block is set below the suspension holdfast, and the anti-reverse sliding block is located at the left side of bonnet assemblies.
The outlet is conical pipe.
The advantages of the utility model and beneficial effect are：
1st, the utility model adds end face soft seal on the basis of the radial seal of traditional swing check valve, improves
Sealing effectiveness.
2nd, the rotation of the utility model piston type opens check valve structure and designs simple, practical function.
Brief description of the drawings
Fig. 1 is the structural representation that check-valves is opened in piston type rotation.
In figure：1. the strip of 9. pilot hole of housing 2. inlet tube, 3. suspension holdfast, 5. active pin shaft, 6. outlet 10.
The mounting flange of 23. anti-reverse sliding block of suppending hole 11. radial sealing surfaces, 19. bonnet assemblies, 21. sealing ring, 22. valve seat 24.
25. the blind flange of sealing gasket 26.
Embodiment
Check-valves, including housing 1, in addition to bonnet assemblies 19 and suspension holdfast 3, the both ends of housing 1 are opened in piston type rotation
Inlet tube 2, outlet 6 are set respectively, are pilot hole 9 between inlet tube 2 and outlet 6, the top of the pilot hole 9 sets peace
Flange 24 is filled, the top of mounting flange 24 sets blind flange 26, sealing is set between the mounting flange 24 and blind flange 26
Pad 25；The end of inlet tube 2 sets valve seat 22, and the right-hand member of valve seat 22 sets bonnet assemblies 19, and the bonnet assemblies 19 have
There are a radial sealing surfaces 11, radial sealing surfaces 11 are bonded with the terminal surface of inlet tube 2 during sealing, and the valve seat 22 opens up circle around inlet tube
Connected in star, the bonnet assemblies 19 set the circular bulge loop being engaged with circular groove, sealing ring 21, circle are set in circular groove
The built-in changeable type flexible material of connected in star, circular bulge loop insertion circular groove, circular bulge loop compress circular groove in closing process
In flexible material, formed second sealing；The upper end of bonnet assemblies 19 is connected with suspension holdfast 3 by active pin shaft 5, institute
State suspension holdfast 3 to be fixed on housing 1, strip suppending hole 10 is provided with the suspension holdfast 3, the active pin shaft 5 is positioned at length
In bar suppending hole 10 and vertical with strip suppending hole 10, active pin shaft 5 can move along the length direction of strip suppending hole 10, motion
Distance is more than the depth that circular bulge loop enters circular groove；The lower section of suspension holdfast 3 sets anti-reverse sliding block 23, described anti-reverse
Turn the left side that sliding block 23 is located at bonnet assemblies 19, bonnet assemblies 19 first land when closed, rear translation, finally close, anti-reverse
Sliding block 23 can play a part of Slow Close, prevent the generation of water hammer, also prevent the generation of the oscillation phenomenon in small pressure difference；
Fluid enters from left side during work, and bonnet assemblies 19 are promoted, and drives active pin shaft 5 to move to b from a points vertically
Point, and start rotation in b points and open, stop when bonnet assemblies 19 encounter outlet 6.When inlet side Fluid pressure reduces and outlet side
When Fluid pressure is high, bonnet assemblies 19 drop to plumbness, and under the promotion of right atrial pressure, and removable pin is driven vertically
Axle 5 moves to a points from b points；Now circular bulge loop enters circular groove, and end face soft seal is realized under the back-pressure of outlet lateral pressure
And radial seal, so as to reach the purpose not leaked.
