The intelligent three-component high-pressure gas cylinder mixed gas filling control cabinet 10 is internally designed in a bilateral symmetry mode, the first gas input pipeline 17, the second gas input pipeline 18 and the third gas input pipeline 19 are respectively connected with corresponding external high-pressure gas source pipelines, the output pipeline 23 is connected to a busbar 40 on the external flower basket type filling platform 11, the busbar 40 is connected with a steel cylinder, and the automatic safe emission pipeline is connected with an external total safe emission pipeline. The method comprises the steps that a user inputs the proportional value of each component gas and the filling pressure of a steel cylinder, the filling pressure of each component is automatically distributed by a PLC, the gas to be filled enters the steel cylinder through a gas input pipeline and an output pipeline 23, the pressure of the output pipeline 23 is monitored at any time, when the filling pressure value of each component is reached, a high-pressure steel cylinder valve on a filling busbar 40 is closed, then residual gas in the filling busbar 40 is diffused through a manual or automatic safety diffusion valve 24, and then the steel cylinder is taken down to finish filling.

The flower basket type filling platform 11 comprises an outer frame 38, a busbar mounting frame 39 is fixedly and fixedly connected in the top of the outer frame 38, a busbar 40 is mounted on the busbar mounting frame 39, a high-pressure hose 41 is connected to a valve 50 of the busbar 40, a first cylinder mounting base and a second cylinder mounting base are further fixedly connected in the top of the outer frame 38, a first cylinder 42 is mounted on the first cylinder mounting base, a second cylinder 44 is mounted on the second cylinder mounting base, a piston rod of the first cylinder 42 is connected with a filling protective cover 43, the filling protective cover 43 is located between the outer frame 38 and the busbar mounting frame 39, a piston rod of the second cylinder 44 is connected with a hose lifting frame 45, the hose lifting frame 45 is located in the busbar mounting frame 39, a through hole is formed in the hose lifting frame 45 above the busbar 40, and is articulated with sleeve 46, the said high-pressure hose 41 crosses the hose crane 45 and crosses the through hole, the sleeve 46 is connected with waiting to fill the steel cylinder, the said high-pressure hose 41 is fixedly connected with sleeve 46.

The bottom frame of the outer frame 38 is provided with an opening on one side, a steel cylinder container grid 47 is placed in the bottom frame, a steel cylinder is placed in the steel cylinder container grid 47, and the high-pressure hose 41 passes through a sleeve 46 to be connected with an inlet valve 50 on the steel cylinder.

When the steel cylinder assembly grid 47 is not pushed into the station, the second cylinder 44 drives the hose lifting frame 45 and the high-pressure hose 41 to be in the upper position, so that the steel cylinder assembly grid 47 is conveniently pushed in; after the steel cylinder assembly lattice 47 is pushed into a station state, the second air cylinder 44 drives the hose lifting frame 45 and the high-pressure hose 41 to fall, so that the high-pressure hose 41 is conveniently connected with the steel cylinders in the steel cylinder assembly lattice 47; in the process of filling the steel cylinder, the first air cylinder 42 drives the filling protective cover 43 to fall down, so that the surrounding environment and operators are protected; after the filling is finished, the first air cylinder 42 drives the filling protective cover 43 to recover to the original position, the operator closes the steel cylinder valve 50, the high-pressure hose 41 is separated from the steel cylinder, and the second air cylinder 44 drives the hose lifting frame 45 and the high-pressure hose 41 to recover to the original position.

And an operation platform is arranged around the flower basket type filling platform 11. The operation of operators is facilitated, and the operation comfort of the operators is improved.

The bus bar 40 comprises a high-pressure gas inlet pipe 48 and each grading branch pipe 49, the high-pressure gas inlet pipe 48 is connected with a first branch pipe, the grading branch pipes 49 are sequentially connected, a valve 50 is connected onto the last grading branch pipe 49, a high-pressure gas inlet is formed in the high-pressure gas inlet pipe 48, and the distances from the high-pressure gas inlet to the valves 50 are equal; the high-pressure gas inlet is connected with a gas source, and the valve 50 is connected with a steel cylinder through a hose.

Various high-pressure gases to be filled into the steel cylinder enter the bus bar 40 from the high-pressure gas inlets, and the distances from the high-pressure gas inlets to the valves 50 are equal, so that when different types of mixed gases are filled and switched, the residual gas in the bus bar 40 enters the steel cylinder in equal quantity, and the filling quality of the mixed gases is ensured.
