Description

Technical Field

[0001] The utility model relates to the technical field of valve body processing, in particular to a fixing fixture for drilling holes in a ball valve core. Background Art

[0002] A ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control.

[0003] Chinese patent CN220445786U discloses a ball valve turning fixture. The utility model adopts a clamping table, which includes a clamping block. The inner surface of the clamping block is an arc groove that matches the surface of the ball valve. When clamping the ball valve, the ball valve can be placed between the clamping blocks, and the first hand wheel is rotated to drive the first worm to rotate and then drive the first worm wheel to rotate, and then drive the positive and negative threaded rods to rotate, so that the clamping blocks are close to each other to clamp the surface of the ball valve. Since the clamping blocks are close to the clamping ball valve at the same time, it is convenient to center the ball valve. At the same time, the self-locking characteristics of the first worm wheel and the first worm are utilized to avoid the rotation of the positive and negative threaded rods, thereby avoiding the loosening of the clamping blocks when turning the pin, thereby improving the stability and efficiency of clamping.
