Description

TECHNICAL FIELD

[0002] Integrated gas pressure reducer is one of the safety devices that various gas pipelines need to be equipped with, which can reduce the upstream gas pressure to slow down the downstream gas impact force, thereby ensuring stable gas output. Pressure reducers are widely used in industrial, medical, laboratory and household fields, and are generally composed of high-pressure cavities, pressure reduction cavities and low-pressure cavities. The pressure in the low-pressure cavity interacts with the pressure reducing valve through a feedback mechanism (such as a spring or diaphragm) to adjust the opening of the valve to achieve the effect of pressure reduction.

[0003] However, most of the existing integrated pressure reducers directly guide external gas into their own devices. Since the gas often contains more than one kind of impurity, it will adhere to the internal elements after entering the device, affecting the service life of the pressure reducer.

[0004] And most of the two ends of the pressure reducer are fixed by flanges, but this structure is not stable. When the internal pressure of the device is high, the pressure reducer will vibrate, and long-term use will cause the pipe to deform. UTILITY MODEL CONTENT
