AI Technical Summary
Existing oxygen pressure regulators have poor pressure relief performance when the pressure relief valve malfunctions, resulting in unstable gas pressure.
A compressed oxygen pressure reducer comprising an inlet housing, an outer housing, and an inner housing is designed. Through the sliding and sealing structure of the inner housing, combined with the cooperation of springs and sealing rings, stable pressure reduction and flow control of the gas are achieved.
This technology ensures that the output gas pressure and flow rate remain stable even when the pressure relief valve fails, thus improving the reliability of the pressure regulator.
