[0002] A ball valve is a fluid control valve. Its working principle is to control the flow of fluid by rotating the ball. The main components of a ball valve include the ball, valve seat, valve stem and handle. When the handle rotates, the valve stem drives the ball to rotate, thereby changing the shape of the channel in the valve body to achieve fluid flow control. It is widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries.

[0003] In the processing of ball valve shaft holes, especially in the processing of V-type ball valve valve core shaft holes, it is necessary to use a ball valve shaft hole processing jig to position and fix the ball valve, so as to ensure the accurate positioning and stable fixation of the ball valve core during the processing. By using the jig, the operator can clamp the valve core on the jig more conveniently and efficiently, thereby saving time and labor costs. However, the existing ball valve shaft hole processing jig has a cumbersome and slow operation process for positioning the ball valve shaft hole, and has low efficiency. Therefore, the present application proposes a ball valve shaft hole processing jig. Utility Model Content
