Abstract
A kind of check valve, including valve body, horizontal run, ball sealer and push rod, it is located at horizontal run medium position in valve body and seal receptacle is set, ball sealer is engaged to form sealing pair with the seal receptacle, open up medium entrance and media outlet respectively on the valve body of seal receptacle both sides, horizontal run sets spring close to medium entrance side, both ends of the spring is abutted with valve body and ball sealer respectively, push rod is located at horizontal run close to media outlet side, push rod is made up of straight-bar and steel ball, straight-bar is abutted with ball sealer, and steel ball is abutted with actuator.The beneficial effects of the utility model are：Abutted at push rod by steel ball with actuator, change sliding friction is rolling friction, and because force of rolling friction is much smaller than force of sliding friction, therefore actuator moment of torsion reduces, valve opening and closing facility.
Description
Art
The utility model is related to a kind of valve, more particularly to a kind of check valve.
Background technology
Currently available technology check valve, the steel ball push rod integral structure of use, as shown in figure 1, push rod head is semicircle
In shape structure, push rod head insertion actuator groove, actuator ejects push rod when rotating, and is now produced between push rod and actuator
For sliding friction, frictional force is big, and resulting actuator moment of torsion is also big, causes driving laborious, is not easy to operation.
Utility model content
In order to overcome the disadvantages mentioned above of existing check valve, the utility model, which is provided, can reduce the list of actuator driving torque
To valve.
The utility model solves its technical problem the technical scheme adopted is that a kind of check valve, including valve body, medium flow field
It is located at medium runner medium position in road, ball sealer and push rod, valve body and seal receptacle is set, ball sealer matches with the seal receptacle
Conjunction forms sealing pair, opens up medium entrance and media outlet respectively on the valve body of seal receptacle both sides, medium runner is close to Jie
Matter inlet side sets spring, and both ends of the spring is abutted with valve body and ball sealer respectively, and push rod goes out positioned at medium runner close to medium
Mouth side, push rod is made up of straight-bar and steel ball, and straight-bar is abutted with ball sealer, and steel ball is abutted with actuator.
The beneficial effects of the utility model are：Abutted at push rod by steel ball with actuator, become sliding friction and rubbed into rolling
Wipe, because force of rolling friction is much smaller than force of sliding friction, therefore actuator moment of torsion reduces, valve opening and closing facility.
Brief description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of embodiment；
In figure：1. spring；2. ball sealer；3. valve body；4. push rod；401. straight-bar；402. steel ball；5. medium entrance；
6. seal receptacle；7. media outlet；8. medium runner；9. actuator.
Embodiment
As shown in Fig. 2 a kind of check valve, including valve body 3, medium runner 8, ball sealer 2 and push rod 4, it is located in valve body 3
The medium position of medium runner 8 sets seal receptacle 6, and ball sealer 2 is engaged to form sealing pair with the seal receptacle 6, in 6 liang of seal receptacle
Medium entrance 5 and media outlet 7 are opened up on the valve body 3 of side respectively, medium runner 8 sets spring 1 close to the side of medium entrance 5,
The two ends of spring 1 are abutted with valve body 3 and ball sealer 2 respectively, and push rod 4 is located at medium runner 8 close to media outlet side, push rod 4 by
Straight-bar 401 and steel ball 402 are constituted, and straight-bar 401 is abutted with ball sealer 2, and steel ball 402 is abutted with actuator 9.
Groove is set on actuator 9, in closed check valve state, steel ball 402 is located in groove, when actuator 9 is rotated
When, steel ball 402 rolls out groove, while promoting ball sealer 2 to depart from seal receptacle 6, opens check valve, during opening herein,
It is rolling friction between steel ball 402 and actuator 9, compared with traditional check valve, reduces the driving torque of actuator 9.
Claims (1)
1. it is located in a kind of check valve, including valve body, horizontal run, ball sealer and push rod, the valve body in the middle part of horizontal run
