AI Technical Summary
The compensation components of existing natural gas pipeline valves are difficult to replace after wear, leading to valve body sealing problems and poor sealing time, which affects the service life and safety of the valves.
A ball valve structure was designed, which includes a flap structure that supports the valve body and flips the valve body. Combined with a compensation and replacement mechanism and a reset sealing component, the valve can be opened and closed quickly by using a positioning magnetic attraction. The compensation component can be easily replaced by a snap-fit structure of a linkage paddle, a telescopic column and a compression spring, and a quick seal can be achieved by using the elastic potential energy of the torsion spring.
It enables convenient replacement of compensation components, reduces the overall disassembly time for valve maintenance, improves sealing reliability and capping efficiency, extends valve service life, and reduces leakage risk.
