Abstract
The utility model discloses a kind of quick action emergency valve, including valve seat, flap, the lower surface of the flap is also threaded with the throttle seat being adapted with the valve seat orifice, and the throttle seat outer wall is cylinder, and its centerline is provided with a cylindrical cavity；Diversion cavity is provided between cylindrical cavity and throttle seat outer wall, the diversion cavity is round platform inclined-plane close to the side wall of cylindrical cavity, and the diversion cavity is faced directly close to the side wall of throttle seat outer wall for cylinder；It is provided through on the throttle seat outer wall to the pod apertures of the diversion cavity.The utility model is provided with throttle seat in the lower surface of flap, throttle seat side wall is provided with pod apertures, and during flap is closed, high-speed Medium fluid enters valve seat epicoele under the water conservancy diversion of helical flow path through pod apertures, 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.
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 is in high-pressure fluid medium emergency cut-off, because the violent change of pressure difference can produce 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, seek
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 quick action emergency valve, and the stop valve exists
On the basis of keeping traditional stop valve sealing pair sealing effectiveness simultaneously, it is possible to increase sealing pair protection against erosion, corrosion resistant performance, have
Help reduce noise.
The utility model is realized by the following technical solutions：
A kind of quick action emergency valve, including valve seat, flap, the lower surface of the flap is provided with the hard seal of ring-type, described
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 lower surface of the flap is also
The throttle seat being adapted with the valve seat orifice is threaded with, the throttle seat outer wall is cylinder, and its centerline is provided with
One cylindrical cavity, for accommodating nut；Diversion cavity is provided between cylindrical cavity and throttle seat outer wall, the diversion cavity is close to circle
The side wall of post cavity is round platform inclined-plane, and the diversion cavity is faced directly close to the side wall of throttle seat outer wall for cylinder；Outside the throttle seat
It is provided through on wall to the pod apertures of the diversion cavity.
Further, it is additionally provided with spiral stream guidance groove on the round platform inclined-plane in the diversion cavity.
Further, the throttle seat is concentric with the hard seal of the ring-type and outer wall coordinates with valve seat interporal lacuna.
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 pod apertures of circumference array, during flap is closed, high-speed Medium
Fluid enters valve seat epicoele under the guide functions of spiral stream guidance groove and diversion cavity through pod apertures, helps to balance both sides pressure difference,
Larger noise will not be produced because of pressure difference violent change；Meanwhile pod apertures also change the flow direction of flap before closing so that
High-velocity fluid is not directly to meet to seal, but is flowed along sealing surface parallel direction, so, greatly reduces high-velocity fluid
Sealing surface is washed away.
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, including valve seat 1, flap 2, the lower surface of the flap 2 is set
There is the hard seal 20 of ring-type, the hard seal 20 of ring-type seals with valve seat orifice upper surface in the switched off state to be coordinated.The valve
The lower surface of valve 2 is also threaded with the throttle seat 3 being adapted with the valve seat orifice, and the outer wall of throttle seat 3 is cylinder, its
Centerline is provided with a cylindrical cavity 30, for accommodating nut；It is provided between the cylindrical cavity 30 and throttle seat outer wall
Diversion cavity 31, the diversion cavity 31 are round platform inclined-plane close to the side wall of cylindrical cavity 30, and the diversion cavity 31 is outside throttle seat 3
The side wall of wall is faced directly for cylinder；It is provided through on the outer wall of throttle seat 3 to the pod apertures 33 of the diversion cavity 31.
As a kind of preferred embodiment, spiral stream guidance groove 32 is additionally provided with the round platform inclined-plane in the diversion cavity 31.
As a kind of preferred embodiment, the throttle seat 3 20 concentric and outer wall of seal hard with the ring-type and valve seat orifice
Gap coordinates.
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) shape after spiral stream guidance groove 32 and the water conservancy diversion of diversion cavity 31
Into current stabilization, the pod apertures 33 are then again passed through.Simultaneously as throttle seat 3 coordinates with valve seat interporal lacuna so that flap 2 is being opened
Unlatching can be steadily oriented during opening.During unlatching, after medium is by pod apertures 33, two can be largely balanced
The pressure difference of side, the unlatching of valve opening valve is not only facilitated, while also change the flow direction of fluid media (medium), not only reduced to close
Front cover washes away, while also contributes 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.
