Description

Technical Field

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

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. When installing the valves, flanges are usually used. During the production and processing of the flanges, the flanges usually need to be polished and set.

This process requires manual flipping of the flange, which wastes manpower, is not conducive to automatic polishing of both sides of the flange, and is not conducive to the use of the polishing device.
