Description

Technical Field

[0001] This utility model relates to the field of valve processing technology, specifically a valve processing grinding machine. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be classified into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in extremely complex automated control systems, with a wide variety of types and specifications.

[0003] When processing valves, the inner wall needs to be ground. Usually, a grinding machine is used for grinding. The valve is fixed to the base, and then the grinding wheel moves down. The base drives the valve to rotate, and the inner wall is ground in conjunction with the grinding wheel. However, there are many valve specifications, and the base can only fix a single specification of valve, which has poor applicability. Therefore, we propose a valve processing grinding machine.
