Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a ball valve sphere surface treatment device. Background Art

[0002] A ball valve is a valve that is driven by a valve stem and rotates around its axis. It is widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries. Ball valves have the advantages of good sealing performance and long service life.

[0003] After grinding, the ball of the ball valve needs to be painted by a surface treatment device so that its service life can be increased. However, the clamping mechanisms of the existing surface treatment devices mostly do not have a rotation function, resulting in the ball of the ball valve needing to be manually rotated and corrected before the surface of the ball can be painted, which reduces the processing efficiency of the ball valve ball. Therefore, a ball valve ball surface treatment device is proposed to solve the above-mentioned problem. Utility Model Content
