AI Technical Summary
The pressure gauges of existing gas pressure reducing valves are too large, resulting in a non-compact structure.
The valve body, valve cover and pressure gauge are integrally molded with a hollow bottom opening, and a compact combination is achieved through the snap-fit structure of the shell and transparent cover, including the fitting design of shoulder, pin hole, snap tongue and annular groove.
This design achieves a compact structure and small size for the pressure reducing valve, while improving the stability and strength of the inlet and outlet ports.
