In guide holder, ball valve core is placed in inside ball valve guide holder, and gasket is located at ball valve guide holder with valve base chamber and is contacted with ball valve core,
Ball valve core crush seal pad under the action of chamber pressure makes ball valve core be pressed in the sealing for forming medium-tight on valve seat；It is described
The internal diameter of valve seat is less than the diameter of ball valve core.
Further, the gasket is round table-like, and the small end of round platform is contacted with ball valve core, and the big end of round platform is equipped with outward
Flange.
Further, the contact surface of the gasket and ball valve core is chamfering inclined-plane.
Further, the position that the valve seat is contacted with ball valve core is equipped with chamfering.
Further, the ball valve housing top inner side is interior concave spherical surface, and the diameter of interior concave spherical surface is bigger than the diameter of ball valve core
5-10mm。
Compared with prior art, the utility model has the advantage of：
1st, ball valve core is placed in inside ball valve guide holder, and gasket is located at ball valve guide holder with valve base chamber and is connect with ball valve core
It touches, ball valve core crush seal pad under the action of chamber pressure, ball valve core is made, which to be pressed on valve seat, can form the close of medium-tight
Envelope, simple in structure, difficulty of processing is small, and use cost is low.
2nd, the position that valve seat is contacted with ball valve core is equipped with chamfering, and ball valve housing top limits ball valve core for interior concave spherical surface, interior
The diameter of concave spherical surface is bigger 5-10mm than the diameter of ball valve core, and check valve during the work time, increases the contact surface with ball valve core
Product, reduces wear rate, extends service life.
3rd, ball valve guide holder and valve base chamber are provided with gasket, check valve during the work time, ball valve core elder generation and gasket
It contacts and is pressed on gasket, then contacted with ball valve seat, effectively alleviate impact of the ball valve core to ball valve seat.
4th, the gasket is round table-like, and the big end of round platform is equipped with outside flange, and flange is located at valve seat and is oriented to ball valve
Between the upper and lower end face of seat, setting sealing performance in this way is more preferable, and the small end of round platform is contacted with ball valve core, can reduce buffering ball spool
Vertical extruding to gasket improves the service life of gasket.
Description of the drawings
Fig. 1 is a kind of structural scheme of mechanism of spherical shape plugging type check valve in the utility model embodiment.
In figure：1st, ball valve core, 2, valve seat, 3, gasket, 4, ball valve guide holder, 5, ball valve housing, 6, valve body.
Specific embodiment
The utility model is described in detail below in conjunction with the drawings and specific embodiments：
As shown in Figure 1, a kind of spherical shape plugging type check valve, including valve body 6, ball valve core 1, valve seat 2, ball valve guide holder 4, close
Packing 3 and ball valve housing 5,1 guide holder of ball valve are socketed in valve body 6, and valve seat 2 is socketed in ball valve guide holder 4, ball valve core 1
It is placed in inside ball valve guide holder 4, gasket 3 is located between ball valve guide holder 4 and valve seat 2, and the big end of the gasket 3 is equipped with method
Orchid, the small end of gasket 3 is tilted upward to be contacted with ball valve core 1.The contact surface of the gasket 3 and ball valve core 1 is chamfering inclined-plane.
