Then, the rotating cylinder is opened through the air inlet control valve, the rotating cylinder drives the docking rotating shaft to rotate, the docking rotating shaft drives the ball valve core to rotate, and the rotation time of the rotating cylinder can be controlled through the air inlet control valve, so that the number of running-in times of the ball valve core can be controlled. After rotating for the specified time, it automatically stops, thereby improving the running-in efficiency and quality of the ball valve core.

[0006] Preferably, two ball valve fixture bodies arranged in parallel at intervals are installed on the base, and the running-in operation of two ball valves can be carried out simultaneously, improving the overall efficiency.

[0007] Preferably, an avoidance hole is provided at the butt joint at the bottom of the fixture support plate and the support bottom plate, which can reduce the overall weight of the fixture and also facilitate better observation of the butt joint situation between the ball valve core and the butt joint rotating shaft.
