The device compresses air as a power source, and the output pressure is proportional to the pressure of a driving air source. When the device works, the input valve 12 is opened firstly, the electromagnetic valve 21 connects the air power pipeline 2 with the booster pump 11, and the pressure regulating valve 22 and the speed regulating valve 23 are used for regulating the pressure of compressed air to enable helium to reach the set pressure; when the helium reaches the set pressure, the pressure transmitter 31 will output a signal and let the solenoid valve 21 switch the interface, and the booster pump 11 stops boosting, so that the output valve 16 is opened to output the high-pressure helium with the rated pressure. The device can drive the pressurization of helium through air, so that the pressure of the helium reaches a required high pressure value.
As shown in fig. 1, filters 5 are provided on the aerodynamic line 2 and the helium pressurization line 1. The filter 22 is capable of removing impurities from the air and helium gas to avoid damaging important components in the pipeline.
