Because the pressure difference between the high-pressure gas bottle 1 and the target container 2 is too large in the initial stage of gas recovery, and the pressure drop rate of the target container 2 is large, along with the recovery of gas, the pressure difference between the high-pressure gas bottle 1 and the target container 2 is reduced, and the pressure drop rate of the target container 2 is also gradually reduced, so that the purpose of controlling the pressure drop rate of the target container 2 can be realized by arranging the flow limiting hole 8. Alternatively, the restricting orifice 8 may be replaced with a flow regulating valve or a throttle valve, and the regulation of the pressure change rate of the target container 2 may be achieved.

when the pressure on the high-pressure gas cylinder 1 side and the pressure on the target container 2 side are close to each other, the gas charging is switched to the gas pressurization mode: the two-position three-way electric control ball valve 34 is switched to the a-c communication state, the two-position three-way electric control ball valve 32 is switched to the a-c communication state, and the two-position four-way electric control ball valve 31 is switched to the a-b communication state. The method specifically comprises the following steps: the filling gas output by the high-pressure gas bottle 1 enters the target container 2 through the a-c passage of the two-position three-way electric control ball valve 34, the pneumatic booster pump 6, the a-b passage of the two-position four-way electric control ball valve 31, the a-c passage of the two-position three-way electric control ball valve 32, the one-way valve 4 and the a-c passage of the two-position three-way electric control ball valve 33 until the working pressure is reached.
When gas recovery is to be performed on the gas in the target container 2, gas recovery is performed by means of gas equilibrium recovery: the two-position three-way electric control ball valve 34 is switched to an a-c communication state, and the gas in the target container 2 is recycled to the high-pressure gas bottle 1 after passing through a c-b passage, a flow limiting hole 8 and a one-way valve 5 of the two-position three-way electric control ball valve 33;
when the pressure of the high-pressure gas bottle 1 side and the pressure of the target container 2 side are close, the gas recovery is carried out by switching to a gas pressurization mode: the gas is recycled to the high-pressure gas bottle 1 through a c-b passage of the two-position three-way electric control ball valve 33, a b-c passage of the two-position three-way electric control ball valve 34, the pneumatic booster pump 6 and an a-c passage of the two-position four-way electric control ball valve 31.
