Technical Field

Background

The ball valve is a valve whose opening and closing member (ball) is driven by valve rod and can make rotary motion around the axis of ball valve, and is mainly used for regulating and controlling fluid medium. The ball valve has the main characteristics of compact and simple structure, relatively small volume, light weight, quick and light opening and closing, convenient maintenance, no limitation of installation direction and random flow direction of a medium. For the ball valve, the ball valve is suitable for common working media such as water, solvent, acid, natural gas and the like, and can also be suitable for media with severe working conditions, such as oxygen, hydrogen peroxide, methane, ethylene and the like.

The defects of the prior art cause that manual running-in cannot be completely replaced by mechanical running-in all the time, so that the production efficiency of the wear-resistant ball valve is not high, and the product quality and the performance are not stable.
