Abstract
The utility model discloses a kind of quick action emergency valve to seal auxiliary structure, including valve seat, flap, the lower surface of the flap is provided with the hard seal of ring-type, the lower surface of the flap also bolt connection has the throttle seat being adapted with the valve seat orifice, the throttle seat outer wall is cylinder, inwall is truncated cone-shaped, and helical flow path is provided with throttle seat inwall；The throttle orifice of circumference array arrangement is offered in the side wall of the throttle seat, the throttle orifice with the helical flow path intersects through throttle seat side wall and in inwall.The utility model is provided with throttle seat in the lower surface of flap, throttle seat side wall is provided with the throttle orifice of circumference array, during flap is closed, high-speed Medium fluid enters valve seat epicoele under the water conservancy diversion of helical flow path through throttle orifice, help to balance both sides pressure difference, larger noise will not be produced because of pressure difference violent change；Meanwhile throttle orifice also changes the flow direction of flap before closing, greatly reduces high-velocity fluid and sealing surface is washed away.
Description
Technical field
It the utility model is related to a kind of stop valve, the sealing pair on more particularly to a kind of stop valve.
Background technology
In the prior art, the structure of stop valve sealing pair is two kinds of structure types of flat seal and conical surface seal.Plane is close
Seal structure is the pattern that valve seat uses plane with flap；Conical surface sealing structure is that valve seat is inner conical surface, and flap is the shape of male cone (strobilus masculinus)
Formula.The stop valve of both structures in high temperature and high pressure gas medium emergency cut-off, due to the violent change of pressure difference can produce it is strong
Turbulent flow, turbulent flow sealing surface can not only be caused it is more serious wash away and corrode, meanwhile, can also produce larger noise.Therefore,
Seeking a kind of sealing pair for improving the above situation will seem very necessary.
Utility model content
In order to overcome the drawbacks described above of prior art, the utility model provides a kind of sealing pair knot of quick action emergency valve
Structure, this sealing pair is on the basis of traditional stop valve sealing pair sealing effectiveness is kept, it is possible to increase sealing pair protection against erosion, corrosion resistant
The performance of erosion, while help to reduce noise.
The utility model is realized by the following technical solutions：
A kind of quick action emergency valve seals auxiliary structure, including valve seat, flap, and it is firmly close that the lower surface of the flap is provided with ring-type
Feng Ti, the hard seal of ring-type seals with valve seat orifice upper surface in the switched off state to be coordinated；Characterized in that, the flap
Lower surface also bolt connection has the throttle seat being adapted with the valve seat orifice, and the throttle seat outer wall is cylinder, and inwall is circle
Platform shape, helical flow path is provided with throttle seat inwall；The throttle orifice of circumference array arrangement is offered in the side wall of the throttle seat,
The throttle orifice with the helical flow path intersects through throttle seat side wall and in inwall.
Further, the outer wall of the throttle seat coordinates with the valve seat interporal lacuna.
Further, the throttle seat and the hard seal of the ring-type are concentric.
Further, the outer diameter of the throttle seat is less than the hard seal outside diameter of ring-type.
The beneficial effects of the utility model are：
The utility model is provided with throttle seat in the lower surface of flap, and throttle seat coordinates with valve seat interporal lacuna, can played
To the orientation of flap.Throttle seat side wall is provided with the throttle orifice of circumference array, during flap is closed, high-speed Medium
Fluid enters valve seat epicoele under the water conservancy diversion of helical flow path through throttle orifice, helps to balance both sides pressure difference, will not be because of pressure difference violent change
Produce larger noise；Meanwhile throttle orifice also changes the flow direction of flap before closing so that high-velocity fluid is not straight
Connect and meet to seal, but flowed along sealing surface parallel direction, so, greatly reduce high-velocity fluid and sealing surface is rushed
Brush.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the utility model.
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining this
Utility model, it is not used to limit the utility model.
The utility model discloses a kind of quick action emergency valve to seal auxiliary structure, including valve seat 1, flap 2, the flap 2
Lower surface is provided with the hard seal 20 of ring-type, and the hard seal 20 of ring-type is matched somebody with somebody with the sealing of valve seat orifice upper surface in the switched off state
Close；The lower surface also bolt connection of the flap 2 has the throttle seat 3 being adapted with the valve seat orifice, and the outer wall of throttle seat 3 is
Cylinder, inwall are truncated cone-shaped, and helical flow path 31 is provided with inwall；Circumference array is offered in the side wall of the throttle seat 3
The throttle orifice 30 of arrangement, the throttle orifice 30 with the helical flow path 31 intersect through the side wall of throttle seat 3 and in inwall.
As a kind of preferred embodiment, the outer wall of the throttle seat 3 coordinates with the valve seat interporal lacuna.
As a kind of preferred embodiment, the seal 20 hard with the ring-type of throttle seat 3 is concentric.
As a kind of preferred embodiment, the outer diameter of the throttle seat 3 is less than the hard outside diameter of seal 20 of ring-type.
Operation principle：When the flap 2 is closed, fluid media (medium) forms current stabilization, Ran Houzai after the water conservancy diversion of helical flow path 31
Flow through the throttle orifice 30.Simultaneously as throttle seat 3 coordinates with valve seat interporal lacuna so that flap 2 can be steady in opening process
Orientation is opened.During unlatching, after medium is by throttle orifice 30, the pressure difference of both sides can be largely balanced, not only
Contribute to the unlatching of valve opening valve, while also change the flow direction of fluid media (medium), not only reduce and sealing surface is washed away, together
When also contribute to reduce flap 2 when closed due to the noise caused by pressure difference.
Above-described embodiment is preferred embodiment of the present utility model, is not the limit to technical solutions of the utility model
System, as long as the technical scheme that can be realized without creative work on the basis of above-described embodiment, is regarded as falling into
In the rights protection scope of the utility model patent.
