Description

Technical Field

[0001] The utility model belongs to the technical field of valve processing, and in particular relates to a welding device for valve processing. Background Art

[0002] Valves are pipeline 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.

[0003] In the process of processing the valve, it is necessary to weld the two ends of the corresponding valve body to the two flanges respectively, so the corresponding valve processing welding device is needed. However, some existing valve processing welding devices still have certain shortcomings in actual use. Since both ends of the valve body need to be welded to the flanges, some common valve processing welding devices require staff to readjust the valve body as a whole after welding one end of the valve body to the flange, which is inconvenient to weld the flange on the other end of the valve body. The operation is cumbersome, and some harmful substances will be generated during the welding process. First, some valve processing welding devices cannot treat the exhaust gas generated by welding, which leads to a relatively bad working environment. After searching, the patent document with the authorization announcement number: CN220217283U discloses a valve processing welding device, which is also unable to treat the exhaust gas generated during the welding process.
