Description

technical field

[0001] The invention belongs to the technical field of grinding and processing of ball valves, in particular to a grinding machine for grinding and processing of balls of ball valves. Background technique

[0002] Ball valve, the 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. The main feature of the ball valve is its compact structure, which is suitable for general working media such as water, solvent, acid and natural gas, and also suitable for media with harsh working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. Suitable for frequent operation, quick and easy opening and closing. Fluid resistance is small. Simple structure, relatively small size, light weight and easy maintenance. The good sealing performance is not limited by the installation direction, and the flow direction of the medium can be arbitrary. As the p...
