Explosion-proof gate valve

By absorbing deflagration energy through explosion-proof pipes and buffer hoses, and providing rigid fixation through a support frame, the explosion-proof housing and motor ensure the safe operation of the shut-off valve in flammable and explosive environments. This solves the problem of shut-off valve damage caused by deflagration of flammable and explosive media, and improves the stability and sealing of the system.

AI Technical Summary

Technical Problem

Existing shut-off valves are prone to damage when flammable and explosive media ignite, rendering them unusable.

Method used

The "Z"-shaped structure of the explosion-proof tube changes the transmission path of the shock wave, and absorbs energy through the buffer hose and shock-absorbing pad. Combined with the support frame, it provides rigid fixation, and the explosion-proof shell and explosion-proof motor ensure system safety.

Benefits of technology

It significantly weakens the intensity of the deflagration shock wave, prevents damage to the main body of the shut-off valve, maintains system stability and sealing, and avoids structural displacement and leakage caused by the impact.

Abstract

This utility model discloses a gate valve with explosion-proof function, relating to the field of gate valves. The utility model includes a gate valve body, both sides of which are connected to connecting pipe flanges via explosion-proof mechanisms. The explosion-proof mechanism includes an explosion-proof pipe with a "Z"-shaped structure. A first buffer hose and a second buffer hose are installed on the explosion-proof pipe to absorb the energy generated by deflagration. This utility model alters the transmission path of the deflagration shock wave through the Z-shaped structure of the explosion-proof pipe, weakening the impact energy intensity. Simultaneously, the first and second buffer hoses absorb high-frequency vibration energy through deformation, preventing the impact from directly reaching the gate valve body. Furthermore, the shock-absorbing pad at the flange connection compresses and deforms to isolate residual impact, preventing bolt shear failure. Its rigid gasket maintains a flat sealing surface, and the shock-absorbing collar dissipates impact energy.
