Description

Technical Field

[0001] The utility model relates to the technical field of copper ball valve processing, in particular to a grinding device for copper ball valve processing. Background Art

[0002] Copper ball valves, also known as ball valves, are mainly used to cut off or connect the medium in the pipeline, and can also be used for fluid regulation and control. The ball valve has a compact structure, reliable sealing, simple structure, and convenient maintenance. The sealing surface and the spherical surface are often in a closed state. During the processing of the copper ball valve, the ball inside the ball valve needs to be polished.

[0003] In the prior art, when grinding the ball of a ball valve, it is necessary to clamp the two ends of the ball valve ball with a pair of arc-shaped clamping plates and rotate it, and then grind the ball valve ball by fixing different grinders. This grinding method has a relatively fixed grinding position for the ball valve ball, and it is necessary to adjust the position of the ball valve ball multiple times for repeated grinding, which is more troublesome.
