Description

Technical Field

[0001] The utility model relates to the technical field of valve welding, in particular to an industrial valve welding tool. Background Art

[0002] Valves are pipe 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. Valves are control components in fluid conveying systems, with functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion, or overflow pressure relief. Valves used in fluid control systems come in a wide variety of varieties and specifications, from the simplest shut-off valves to the various valves used in extremely complex automatic control systems. 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] However, some industrial valve welding tools now usually use clamping blocks to fix the valves in order to perform precise welding operations. However, the clamping blocks of existing welding tools usually adopt an arc design to match the outer contour of the valve. However, the angle of this arc is usually fixed and cannot be adjusted according to the size changes of the valve. Therefore, when the size of the valve to be welded exceeds the applicable range of the clamping block, the existing welding tool cannot effectively clamp and fix the valve, resulting in the inability to perform welding operations. For this reason, we propose an industrial valve welding tool to solve the above problems. Utility Model Content
