Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for processing a ball body of a ball valve. Background Art

[0002] Ball valves are mainly used to cut off, distribute and change the flow direction of the medium in pipelines. They can be closed tightly by rotating 90 degrees and applying a very small torque. Ball valves are most suitable for use as switches and cut-off valves. Ball valves are widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries. The ball is the main component of the ball valve. The ball is a hollow spherical structure. The surface of the two-way ball valve body is provided with two symmetrical pipe holes for connecting with the pipe body. When processing the ball of the ball valve, a fixture is needed to clamp and fix the ball.

[0003] At present, some clamps clamp the ball of the ball valve by moving two sets of clamping blocks towards each other. It is not convenient to rotate the ball of the ball valve after clamping. However, when performing processing operations such as grinding on the ball, the angle of the ball needs to be adjusted. In this way, the ball needs to be repeatedly removed to adjust the angle and then re-fixed with the clamp, which is time-consuming and labor-intensive, and is troublesome to use, affecting the processing efficiency. Therefore, a clamp for ball valve ball processing is proposed. Utility Model Content
