Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to a ball fixing device for ball valve processing. Background Art

[0002] As is known to all, a ball valve, a valve in which the opening and closing member (ball) is driven by a valve stem and rotates around the axis of the ball valve, can also be used for the regulation and control of fluids. Among them, a hard-sealed V-type ball valve has a strong shear force between its V-type ball core and a metal valve seat welded with cemented carbide, which is particularly suitable for media containing fibers, tiny solid particles, etc. When processing the ball in the ball valve, it is necessary to fix it first. The traditional fixing device is to clamp it with a plane. Since the clamping plane is too smooth, the ball valve may shift during the clamping process, and the shift may cause the drilling to be incomplete. If the clamping plane is too hard, the surface of the ball may be squeezed and damaged. A damaged ball may lead to a poor seal and poor practicality. In view of the above problems, the present application designs a ball fixing device for ball valve processing. Utility Model Content
