Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing, referring to Fig. 1-9: a kind of leakproof
Type three-way ball valve, including valve body 1, bonnet 2, valve ball 4 and valve rod 6 are equipped with handle 8 on valve rod 6, and between handle 8 and valve body 1
Increase has gasket 7, and handle 8 is fixed by nut 10, is additionally provided with check washer 9 between the two, at least one O is arranged on valve rod
Type circle 5, the valve ball 4 are installed in valve body 1, and bonnet 2 is spirally connected with valve body 1, and valve ball 4 is closed in valve body 1, the valve rod 6
It is connect through valve body 1 with valve ball 4, sealing ring 3 is provided on the port that the valve body 1 and bonnet 2 are connected to valve ball 4, it is close
Seal 3 contacts with each other with valve ball 4, wherein it is provided with fixing groove on the port of the valve body 1 and the port of bonnet 2, it is described close
Seal 3 is installed in fixing groove, and the bottom of the fixing groove is provided with several placement holes, and setting is flexible in the placement hole
Part, the elastic component act on sealing ring 3, and the elastic component is elastic rubber or spring.
In actual use process, due to being hardened after elastic rubber aging, the ratio of rebound loss is more serious, so
Preferably select spring.
And placement hole using it is rectangular and round when can be used coil component spring, when using cone, need use Conical Projectile
Spring, so, embodiment one is described by circle of placement hole, is described in embodiment two by cone of placement hole.Its
In, the fixing groove on the port of the valve body 1 is fixing groove I 101, and the placement hole in fixing groove I 101 is placement hole I 102, institute
Stating the fixing groove on the port of bonnet 2 is fixing groove II 201, and the placement hole in fixing groove II 201 is placement hole II 202.
Embodiment one
Such as Fig. 3 and Fig. 5, placement hole I 102 and placement hole II 202 are circle in the embodiment, the spring 11 of inside setting
For coil component spring, and length is greater than the hole depth of placement hole I 102 and placement hole II 202, placement hole I to spring 11 in its natural state
102 are evenly distributed in fixing groove I 101, at least three, could smoothly support sealing ring 3, and similarly, placement hole II 202 is equal
It is even to be distributed in fixing groove II 201, at least three.
After valve ball 4 is installed in valve body 1, spring 11 is in compressive state, with resilience always to act on sealing ring 3,
Come into full contact with sealing ring 3 with valve ball 4 always, even if the screen resilience of spring 11 can be adjusted automatically in the case where sealing ring 3 is worn
The gap between sealing ring 3 and valve ball 4 is saved, compensation is made, remains unchanged leakproofness.
