Description

Technical Field

[0001] This utility model relates to the field of valve processing and cutting fixture technology, specifically a cutting fixture for valve processing. 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 as shut-off valves, check valves, regulating valves, etc.

[0003] Valves are control components in fluid transport systems, serving functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, and pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in highly complex automated control systems, exhibiting a wide variety of types and specifications.

[0004] During valve processing, clamps are used to hold and fix the valve to increase stability. Then, the excess pipe or scrap material is cut off. However, traditional clamps have limited functions, are not easy to adjust after clamping, and require workers to be below the cutter to perform the clamping work. Some workers may disassemble or process the valve without stopping the cutter in time in order to increase efficiency, which can easily lead to safety accidents. Therefore, the use of clamps is inconvenient. Utility Model Content

It has two sets of fixture structures, which can be replaced as needed. One set is used for processing while the other set clamps the valve body, thereby improving processing efficiency. Furthermore, the separation of the fixture from the cutting tool increases safety during use.
