Limit effect.
The utility model is further arranged to: sealing mechanism is equipped between the valve rod and valve body, which includes
Several installation annular grooves being set on valve rod, each install in annular groove are equipped with sealing element, and the inner sidewall of the sealing element is in indent knot
Structure, the lateral wall of sealing element are in outer male structure.
By using above-mentioned technical proposal, sealing mechanism is equipped between valve rod and valve body, which includes being set to
Several installation annular grooves on valve rod, each install in annular groove are equipped with sealing element, are arranged by above structure, increase valve rod and valve
Sealing effect between body, and inner sidewall is set in concave inward structure by the sealing element, the lateral wall of sealing element is in outer umbo
Structure, in the lateral wall stress of outer male structure, so that the inner sidewall of concave inward structure carries out good covered effect, to improve good
Good leakproofness.
The utility model is further arranged to: the thickness of the blend stop is increased from the bottom of valve ball toward between edge direction.
By using above-mentioned technical proposal, the thickness of blend stop is increased from the bottom of valve ball toward between edge direction, by adopting
It is arranged with above structure, increases gradual limit effect between limited block and valve ball, it is ensured that good structural stability.
The utility model is further arranged to: the limited block is made in rubber material.
By using above-mentioned technical proposal, limited block is made in rubber material, the limit being arranged by using rubber material
