AI Technical Summary

Technical Problem

The existing shut-off valves have difficulties in processing and maintenance, especially the pressurized channel and pressure relief channel need to be formed integrally with the valve body, resulting in increased processing difficulty, reduced yield, and complex non-rotating process of the piston.

Method used

A hydraulic rapid adjustment shut-off valve is designed. By integrating the pressurized channel and the pressure relief channel on the piston, special processing of the valve body is avoided. The piston is relatively easy to form and process, and is easy to replace or reprocess during later maintenance.

Benefits of technology

It realizes a shut-off valve that is easier to process and later repair, reducing manufacturing difficulty and maintenance costs, and improving product yield and service life.

Abstract

The present invention discloses a hydraulic quick-adjusting stop valve, comprising a valve body, a valve cavity in the middle of the valve body, and a water inlet and a water outlet, the water inlet and the water outlet are connected through a cut-off surface channel, the cut-off surface channel is located at the lower opening of the valve cavity; a piston is arranged in the valve cavity; the stop valve also comprises a pressurizing channel and a pressure relief channel, the lower end of the pressurizing channel is connected to the water inlet, and the lower end of the pressure relief channel is connected to the water outlet; the stop valve also comprises a rotating plate, an arc groove is arranged on the lower surface of the rotating plate, the arc groove and the upper part of the valve cavity are connected, the arc groove and the upper end of the pressurizing channel and the upper end of the pressure relief channel match; the pressurizing channel and the pressure relief channel are arranged on the piston, the rotating plate is pivotally connected to the upper part of the piston, and the piston cannot rotate compared to the valve cavity. The advantages of the present invention are: easier to process and later maintenance.
