AI Technical Summary

Technical Problem

Existing pressure control valves have complex structures and significantly slow response speeds, making it difficult to adapt quickly and accurately to dynamic changes in system pressure, thus affecting the system's operating efficiency and stability.

Method used

A pressure control valve comprising a housing assembly and a valve body assembly is designed. The housing assembly has an input channel, an output channel, a pressure relief channel, and a pressure control channel. The valve core is movable to adjust the opening and closing of the channel or the size of the passage cross section. Combined with an elastic structure and sealing components, it achieves rapid response to pressure changes.

Benefits of technology

It achieves rapid response to pressure changes, has a compact structure with few parts, is easy to install and maintain, adapts to various working conditions, and improves the system's operating efficiency and stability.
