[0032] In this example, by setting up a grinding assembly 4, pipes with valves of different sizes can be ground. The cylinder 412 is started to push the grinding plate 413 to move, and drives the grinding wheel 1 415 and the grinding wheel 2 4111 to grind the rotating valve. When it is necessary to grind valve pipes of different sizes, the screw 417 is rotated, and under the action of the threaded hole 416, the concave plate 2 418 and the grinding wheel 2 4111 will be driven to move, thereby realizing grinding of different sizes, thereby achieving the grinding effect.

Then, by setting the grinding assembly 4, pipelines of valves of different sizes can be polished, and the cylinder 412 is started to push the grinding plate 413 to move, and drive the grinding wheel 1 415 and the grinding wheel 2 4111 to grind the rotating valve.
