AI Technical Summary
Technical Problem
The existing pressure reducing valves have poor sealing performance of the internal structural piston, resulting in gas leakage, unstable pressure reduction performance, and cannot effectively adjust the air pressure.
Method used
An integrated proportional pressure reducing valve is designed, and the pressure relief chamber, limit counterborer, diaphragm, lower pressure block, top rod and rotary handle are set on the lower housing, and the diaphragm and top rod are driven by the rotary handle. , forming a conical hole gap to achieve proportional adjustment and sealing of air pressure.
Benefits of technology
It effectively avoids gas leakage, realizes stable conversion and proportional adjustment of air pressure, and improves the performance of the pressure reducing valve.

Abstract
An integrated proportional pressure reducing valve belongs to the technical field of pressure reducing valves. The handle for rotating the handle to press down and the elastic diaphragm are arranged, the diaphragm is pressed between the upper shell and the lower shell through the upper shell, the diaphragm is tightly pressed through connection of the upper shell and the lower shell, and leakage is avoided; the rotary handle capable of being rotationally pressed downwards is arranged, the thread pitch of threads on the rotary handle and the gap between the conical holes of the ejector rod are arranged in proportion, the rotary handle is pressed downwards to drive the membrane to be pressed downwards, the membrane is pressed downwards to drive the ejector rod to be pressed downwards, the gap between the ejector rod and the conical hole of the pressing block is achieved, and therefore proportional pressure reduction adjustment is achieved.
