The pressure stabilizing valve is arranged between the primary decompression valve and the secondary decompression valve and is used for enabling gas output to trend to a constant value;
the elastic coil is positioned at the top in the middle square body of the gas control device.
5. The two-stage gas output control device according to claim 1, wherein the gas control device intermediate cube comprises: a feedback control circuit;
the two feedback control circuits are arranged and positioned on the other side in the middle square body of the gas control device.
6. A two-stage gas output control method is characterized in that:
the high-pressure gas tank is filled with gas in advance through the gas charging port, and the gas is conveyed into the gas control device through the gas output port;
when the water depth is 10 meters to 10 meters, decompressing the gas in the gas control device by using a first-stage decompression valve, outputting constant value 0.25Mpa gas by using a pressure stabilizing valve, supplying the constant value 0.25Mpa gas to a first pneumatic executing mechanism, and when the gas consumption in the first pneumatic executing mechanism causes insufficient air pressure, performing air supplementing by using a feedback control circuit through joint control of a pressure sensor and a first electromagnetic valve;
when the water depth is 0m, the second electromagnetic valve controls the second-stage decompression valve to output 0.5Mpa gas, and the gas is supplied to the second pneumatic actuating mechanism.
