Description

Technical Field

[0002] A valve is a pipe fitting used to open and close pipes, control flow direction, and adjust and control the parameters of the conveyed medium (such as temperature, pressure, and flow). It has functions such as shutoff, regulation, diversion, reverse flow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media.

[0003] The existing valve grinding device fixes the valve by placing the valve on a fixed seat of the grinding device and supporting the inner wall of the valve with the fixed legs on the fixed seat. However, since some valves are heavy, the valve needs to be accurately aligned on the upper part of the fixed seat, and the fixed legs need to be on the inner side of the valve. If the operation is not done properly, the valve may easily collide with the fixed legs, causing damage to the valve or the fixed legs. Utility Model Content
