When the gas-tight quick connector is used, the self-tight quick connector 7 is inserted into a life jacket, the gas source 1 and the reversing control valve 6 are opened for inflation, and the gas tightness of the life jacket can be detected through the numerical value change of the digital display pressure gauge 8. Specifically, the detection gas flows out of the gas source 1, flows into the control pipeline and the inflation pipeline simultaneously, the magnitude of preset pressure in the pipelines is controlled through the gas pressure control valve 2, and the flow rate of the gas in the inflation pipeline is controlled through the inflation pressure regulating valve 4, so that the inflation pressure is controlled, the inflation pressure can be prevented from overshooting, and the service life is prolonged.
