Description

Technical Field

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

[0002] Valves are pipe accessories used to open and close pipes, 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. Valves are control components in fluid conveying systems and have functions such as shutoff, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. After the valve is produced, it is generally necessary to perform secondary processing on it, and the position of the valve needs to be fixed before secondary processing.

[0003] However, some clamping tools available now cannot adjust the level of the valve, which results in inaccurate horizontal positioning of the valve during processing, making it easy for defects to occur during valve production, and cannot meet the use requirements of valve production and processing. Therefore, we propose a clamping tool for valve processing to solve the above problems. Utility Model Content
