Description

Technical Field

[0001] The utility model relates to the technical field of welding devices for repairing valve body leakage, in particular to a welding device for repairing valve body leakage. Background Art

[0002] During long-term use, the valve body will inevitably have some problems, such as cracks and holes in the valve body, which will cause gas leakage. In such cases, the valve body needs to be repaired. Among various repair measures, replacing the valve body is the most common and effective method. During the development of special equipment and processes such as cutting and welding involved in online replacement of the valve body, cutting and welding operations need to be repeated. If a valve with the same manufacturing structure as the original is used, multiple operations will cause the material near the valve body and valve seat groove to deteriorate, and even the valve seat and valve body to be severely deformed. When replacing the valve body, the valve body needs to be welded. The existing docking methods include multiple people supporting by hand, using a crowbar and manually pulling a hoist, etc. The main problem is that many operators are required and the operation is inconvenient. Based on this, a welding device for valve body leakage repair is proposed to solve the above problems. Utility Model Content
