Description

technical field [0001] The invention relates to a ball valve disassembly tooling and an installation and disassembly method, belonging to the technical field of valve installation. Background technique [0002] Ball valve has become one of the most widely used valves due to its reliable sealing, simple structure and convenient maintenance. Compared with the side-mounted ball valve, the top-entry ball valve has the advantages of fewer leakage points and less influence of pipeline stress on it. At present, the top-entry ball valve is widely used in LNG pipelines, LNG carriers and receiving stations. Therefore, many domestic valve manufacturers All have invested a lot of manpower, material resources and financial resources to study the top entry ball valve. [0003] Such as figure 1 As shown, a top-entry ball valve researched by the applicant mainly includes a valve body 1 with a circular inner cavity, a ball 2 placed in the valve body, a retainer 3 sealingly connected with t...
