The intake valve 21 is an electronic one-way valve, which means that the gas in the intake mechanism 1 can only flow into the pressure chamber 3 in one direction, and the gas in the pressure chamber 3 does not flow into the intake mechanism 1 in the reverse direction. After the air inlet valve 21 is opened, the air inlet mechanism 1 is opened for inflation, and after the system reaches a preset pressure value, the air inlet valve 21 is closed, so that the whole pressure chamber 3 system is in a closed pressure maintaining state.

In addition, the state of the float at a certain pressure value can also be determined by the numerical control box 62. When the pressure of the pressure chamber 3 reaches a certain pressure value, the numerical control box 62 controls the one-way valve to be closed and stops pressurizing; when the pressure of the system is lower than a certain pressure value, the numerical control box 62 controls the check valve to open and start pressurization, so that the system is in a pressure maintaining state. Preferably, the numerical control box 62 can set the highest pressure value to prevent the pressure in the pressure chamber 3 from being too high to explode. After the pressure resistance and the proper water depth of the buoy are determined, the pressure relief ball valve is opened, gas in the pressure cabin 3 is discharged, after the pressure gauge 61 shows that the pressure in the cabin is zero, the drainage one-way valve is opened, water in the pressure cabin 3 is discharged, the buoy is taken out, and other buoys of other types are replaced to carry out the same test.
