AI Technical Summary

Technical Problem

Existing directional control valves suffer from problems such as rapid seal failure, high drive energy consumption, large medium pressure loss, and valve plate jamming, which affect service life and system efficiency.

Method used

The system employs a symmetrically arranged double valve plate structure and a linkage drive mechanism, combined with a stepped toothed sealing ring and an axial boss design, to achieve torque balance and sealing reliability of the valve plate. The linkage design of the symmetrical connecting rod group reduces drive energy consumption, and the optimized flow channel design reduces medium pressure loss.

Benefits of technology

It achieves significantly reduced drive energy consumption, high sealing reliability, stable operation, compact structure and strong applicability, and is suitable for high temperature and corrosive environments, extending the service life of valves and improving system efficiency.
