AI Technical Summary

Technical Problem

Traditional gate valves are prone to wear, leakage, and uneven pressure reduction in high-pressure fluid environments, making it difficult to meet the requirements of complex working conditions and high-precision control.

Method used

A high-strength shut-off valve with flow diversion and pressure reduction was designed. It adopts a flow diversion counteractor and flow obstruction guide plate structure to reduce fluid pressure through flow diversion and counteracting paths. Combined with the diamond and trapezoidal structure design, it achieves uniform distribution of fluid and kinetic energy cancellation.

Benefits of technology

It improves the wear resistance of valves and system stability, reduces fluid pressure fluctuations, and ensures the safety and precise control of fluid transportation.

Abstract

The high-strength stop valve capable of shunting and reducing pressure comprises a valve body, the valve body, a shunting hedging device and a discharge pipe opening are integrally arranged together and communicated with one another, a valve cover assembly is installed on the valve body, the lower end of a driving valve rod installed on the valve cover assembly extends into the valve body, and the lower end of the driving valve rod extends into the valve body. The valve seat is arranged in the valve body and connected with a valve clack arranged in the valve body, and the valve clack is arranged above the valve seat in the valve body. A hand wheel is fixedly mounted at the upper end of the driving valve rod; the split-flow hedging device is arranged in the valve body, the rhombic split-flow transverse table divides liquid into an upper flow channel and a lower flow channel, the trapezoidal flow blocking guide plate and the transverse table form a double-split-flow hedging path, efficient pressure reduction is counteracted through kinetic energy of the liquid, impurities can be blocked and dispersed, complex working conditions can be adapted, and the stability and safety of a system are improved.
