Technical Field
[0001] This utility model relates to the field of valve technology, specifically to an auxiliary device for replacing valve sealing rings. Background Technology
[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters of the conveyed medium. According to their functions, they can be divided into shut-off valves, check valves, and regulating valves. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, flow guidance, backflow prevention, pressure stabilization, flow diversion, or overflow pressure relief. Valves seal the connection points through sealing rings.
