AI Technical Summary

Technical Problem

The existing gate valves have a single installation method, which leads to a gradual decrease in sealing effect over time, resulting in the risk of media leakage and failing to meet the adaptability and safety requirements under complex working conditions.

Method used

The system employs reinforcing components, including rings, threaded rings, annular rings, sliding rods, springs, and fixing blocks. Through threaded connections and spring reset mechanisms, it pressurizes and fixes external pipes to prevent loosening.

Benefits of technology

It improves the ease of installation and sealing performance of the gate valve, reduces the risk of media leakage, and enhances its applicability and safety under complex working conditions.
