Ring is located in the first seal groove, and second sealing ring is located in the second seal groove, and supporting pin, the valve are equipped in the valve body
Internal wall side is equipped with the first fixing groove, and the other side is equipped with the second fixing groove, and described supporting pin one end is located in the first fixing groove,
The other end is located in the second fixing groove, and the supporting pin bottom surface is fixedly connected with return spring, the bottom end of the return spring
It is connected with spool link block, spool link block bottom is fixedly connected with spool, and the section of the spool is trapezoidal.
Second sealing ring is located at the lower section of the first sealing ring.
First limited block, the second limited block are symmetrical arranged.
The utility model has the following beneficial effects:
Sealing ring dual-seal is used in 1 the technical program, effectively slurry is avoided to exosmose, sealing effect is good.
Spring and spool are rigid member in 2 the technical program, and it is easily-deformable to overcome rubber component in the prior art
Defect.
It is sealed using spool with valve body in 3 the technical program, changes traditional welding structure, implementation result is good
It is good.
The effect of limited block can play position-limiting action, fast and easy installation to valve body in 4 the technical program.
The problem of 5 the technical program whole designs are reasonable, safe and reliable, effectively avoid backflow of slurry, is conducive to big model
Enclose popularization and use.
