AI Technical Summary
Traditional leak-proof shut-off valves are installed using simple threaded rod connections and waterproof tape seals, which can easily lead to leaks at the connection points after long-term use, resulting in poor leak-proof performance.
It adopts a two-way sealing structure. Through the design of the mating ring and threaded rod, it uses rubber sealing rings and plugs to achieve bidirectional compression between the fixed ring and the mating ring, forming a highly efficient seal.
This improves the valve's sealing performance, prevents leakage, and ensures a tight seal during long-term use.
