Abstract

The invention discloses a device for achieving constant-pressure low-pressure gas flow increasing. A shell is included. An air inlet is formed in one side of the shell, and an air outlet is formed inthe other side. The air inlet is connected with one end of an adjusting valve, the other end of the adjusting valve is connected with one end of a drive rod, the other end of the drive rod is connected with one ends of membranes, the other ends of the membranes are fixed to the shell, the two membranes are arranged, a spring installing plate is arranged on the upper surfaces of the two membranes,one end of a spring is fixed to the spring installing plate, the other end of the spring abuts against a spring housing, and the spring housing is fixed to the shell. The adjusting valve and the driverod are located in a pressure adjusting chamber. The adjusting valve is movably connected to the inner surface of the shell, and the pressure adjusting chamber communicates with the air outlet. The device is simple in structure, the air pressure can be effectively stabilized, stable gas supply of a gas supply device is guaranteed, and usage is facilitated for users.

Description

technical field [0001] The invention relates to the technical field of constant pressure valves, in particular to a device and method for realizing constant pressure and low pressure gas flow increase. Background technique [0002] The constant pressure valve is generally installed on the pipeline, the purpose is to convert the high-pressure air source output by the external air intake device into a low-pressure stable air source, and its air outlet is externally connected to the air supply device. In today's market, many constant pressure valves have complex structures and are prone to problems. It is difficult to ensure a constant gas output, which leads to unstable gas supply of the gas supply device and affects the use of users. Contents of the invention [0003] The object of the present invention is to provide a device and method for increasing the flow of gas at constant pressure and low pressure, so as to solve the problems raised in the above-mentioned background ...
