End face is provided with circular erecting bed, and the diameter of erecting bed is more than the maximum gauge of the upper body of rod, the middle part of the top end face of erecting bed
Provided with upper installation end, upper installation end has four side walls and a top end face, and the top end face of upper installation end is spherical end surface；Lower beam
Lower installation end is installed, lower installation end has four side walls and a bottom face, the bottom face of lower installation end on the lower surface of body
For burnishing surface.
The utility model is further arranged to：The two of which side wall of the upper installation end is parallel to each other, two other phase
To the curved side wall of side wall, the nock of two curved walls is oppositely arranged.
The utility model is further arranged to：Wherein two relative side walls of the lower installation end to inward side to provided with
Step is formed between the bottom face of cutting face, two cutting faces and lower installation end.
The utility model is further arranged to：Spacing between two cutting face is gradually reduced under upper.
The utility model is further arranged to：Other two relative side walls of the lower installation end are by upper and lower two parts
Composition, upper part is the radian identical curved wall with the lower beam body sidewall of opposite position, and lower part is radian phase
The curved wall small compared with the radian of the curved wall of upper part.
The utility model is further arranged to：Bottom face of the downside of the curved wall of the lower part with lower installation end
Between be provided with chamfering.
The utility model is further arranged to：Spacing between other two relative side walls of the lower installation end is by up to
Under it is equal.
The utility model is further arranged to：The diameter of spacer ring between two groove and the diameter of the upper and lower body of rod
It is equal.
By using above-mentioned technical proposal, the technique effect that the utility model is reached is：Pass through the ball valve to environment-friendly type
The overall structure of valve rod is redesigned, and is improved the tidiness of product and the quality of product, is effectively reduced environment-friendly type
Ball-valve valve rod rotation when resistance, improve greasy property, and to obtain using the quality of the valve of this product
Certain lifting, reduces waste and maintenance, the purchase cost of manufacture material, reduces the waste of manufacture material.
