The utility model discloses a valve body passes through valve body cooperation portion and can form tight sealedly with the valve clack, when needs end the medium, can effectively prevent the seepage of liquid.
Description
Technical field
The utility model is related to aviation high-pressure stop valve technical field, it particularly relates to a kind of high-pressure stop valve body.
Background technology
Stop valve is a kind of most popular valve, and the closure principle of stop valve is, by valve rod pressure, to make flap close
Front cover is brought into close contact to prevent flow of media with sealing surface of seat.Stop valve valve clack sealing surface and valve base sealing during opening and closing
Frictional force between face is little, relatively durable, and Lift is less, easy to manufacture, easy to maintenance, is applicable not only to mesolow, and
And it is applied to high pressure.
It is the auxiliary section coordinated with valve rod that the shape of current high-pressure stop valve body mostly is top, and bottom is liquid communication
Cavity, due to stop valve structure limit, can cause between stop valve body and flap, to form tight cooperation, so as to
Medium can be from both contact positions flow direction outlet side.
Utility model content
The purpose of this utility model is to provide a kind of high-pressure stop valve body, above-mentioned with overcome currently available technology to exist
It is not enough.
For realizing above-mentioned technical purpose, what the technical solution of the utility model was realized in：
A kind of high-pressure stop valve body, the top of described valve body are provided with valve rod mobile cavity, and the bottom of described valve body sets
There is the liquid flow cavity of connection, described valve rod mobile cavity is connected with liquid flow cavity；The left side of described liquid flow cavity is
Import, the right side of described liquid flow cavity is outlet, and the bottom of described liquid flow cavity is provided with breaks cooperation with the valve of valve rod
Auxiliary section, described auxiliary section is the structure of the undercut to described liquid flow cavity 4.
Further, described auxiliary section includes the conical surface of several tapers and identical length etc., and described is two neighboring
Plane is connected between the conical surface.
Preferably, the taper of the described conical surface is 1:20-1:10.
Preferably, described cone surface which area and plane area ratio are 8:1-15:1.
Preferably, the described conical surface and plane are connected by fillet, and the radius of described fillet is 5mm.
After above-mentioned technical proposal, the utility model has following beneficial effect：Valve body of the present utility model passes through
Valve body auxiliary section can form tight sealing with flap, when needing to end medium, can effectively prevent liquid
Seepage.

As shown in Figure 1-2, a kind of high-pressure stop valve body described in the utility model embodiment, described valve body 9 it is upper
Portion is provided with valve rod mobile cavity 1, the liquid flow cavity 4 that the bottom of described valve body 9 is communicated with, described valve rod mobile cavity 1 with
Liquid flow cavity 4 is connected；The left side of described liquid flow cavity 4 is import 2, and the right side of described liquid flow cavity 4 is outlet
3, the bottom of described liquid flow cavity 4 is provided with the auxiliary section 5 for breaking cooperation with the valve of valve rod, and described auxiliary section 5 is to described
Liquid flow cavity 4 undercut structure, described auxiliary section 5 includes the conical surface 6 of several tapers and identical length etc.,
Plane 7 is connected between the described two neighboring conical surface 6.
In one embodiment, the taper of the described conical surface 6 is 1:20-1:10.
In one embodiment, described 6 area of the conical surface and 7 area ratio of plane are 8:1-15:1.
In one embodiment, the described conical surface 6 and plane 7 are connected by fillet 8, and the radius of described fillet 8 is
5mm。
Auxiliary section of the present utility model can form tight sealing with flap, and auxiliary section is connected by some conical surfaces and plane
Connect, when stopping liquid is needed, rotation valve rod is in close contact flap and plane or the conical surface.The conical surface of the present utility model
The data such as 6 taper, 7 area ratio of 6 area of the conical surface and plane, the radius of fillet connected between the conical surface and plane be through
The optimal data that long term test is obtained.
Preferred embodiment of the present utility model is the foregoing is only, it is not to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
