[0002] During the processing of the ball valve, its exterior needs to be ground to keep it smooth. A grinding device is needed for grinding. At the same time, after the ball valve ages, its sealing and flow control performance will gradually decrease. At this time, measures need to be taken to repair it. Valve grinding is a common repair method. It can grind the worn parts to remove surface defects and oxidation, restore its original smoothness and precision, so as to achieve the purpose of optimizing valve performance and effectively improve sealing performance and service life. In other words, the grinding device for ball valve processing can be used for grinding during ball valve production, and can also be used for grinding for later repairs. The common grinding devices for ball valve processing on the market are inefficient when continuing to grind the ball surface of the ball valve, and require manual control to support the grinding, which poses a safety hazard. In addition, during the grinding process, abrasives will be thrown out, which will cause waste. If the grinding pad is not fixed firmly enough, it is easy to slide, affecting the grinding effect.
