[0002] High-pressure ball valve is an important type of valve. During the processing, burrs, rust, dirt and other impurities often remain on the surface of the ball valve. In order to make the surface of the ball valve smooth, a grinding and cleaning device is needed to grind and clean the ball valve to make the sealing surface smoother, thereby improving the sealing performance of the ball valve.

[0003] The existing high-pressure ball valve grinding and cleaning device is mainly composed of a motor and a grinding roller. When the surface of the ball valve is ground, the motor is operated to rotate the grinding roller, so that the surface of the ball valve can be ground and cleaned, thereby removing burrs, rust, dirt and other impurities remaining on the surface of the ball valve.
