AI Technical Summary

Technical Problem

The pressure reducing valve, a key component of existing gas flares, has low reliability requirements, which cannot guarantee the safety and stability of the flare.

Method used

A gas torch pressure regulating valve was designed, including a gas delivery pipe, a gland, a fastening cover, and a valve body. The design of the limiting protrusion and limiting recess ensures precise alignment of the gland. Combined with the setting of annular interval and pressure regulating hole, it realizes stable gas guidance and pressure balance, and enhances sealing performance and assembly reliability.

Benefits of technology

It improves the assembly efficiency and reliability of gas torches, ensures stable gas flow, prevents gas blockage and backflow, forms stable flame combustion, and enhances the safety and reliability of the torch.
