Under the guidance of the guide rod 42, the sealing valve 35 slides in the slideway 34, thereby stopping the gas supply to the storage tank 15, and by turning the screw The threaded rod 51 drives the turntable to descend due to the threaded relationship, and then adjusts the elasticity of the drum piece 32 through the extension and compression of the first spring 52, thereby adjusting the preset pressure value in the storage tank 15. The pressure in the storage tank 15 pushes the sliding plug 62 to slide in the detection cylinder 61. When the pressure values ​​in the gasification pipe 13 and the storage tank 15 are stable, the sliding plug 62 is stabilized in the detection cylinder 61, and the position spacing of the sliding plug 62 is adjusted by the distance sensor 64. When the distance sensor 64 detects that the position of the sliding plug 62 is unchanged, the solenoid valve 65 is controlled to close, and the gas filling in the storage tank 15 stops.
