Problems solved by technology
[0002] In reality, there are many gas storage equipment that need to store a variety of mixed gases, but most of the existing inflatable equipment mixes multiple gases before inflating, and then fills the mixed gas into the gas storage bottle. The gas mixing device leads to a complex structure of the inflatable equipment and a high failure rate. After the inflation is completed, due to the different gas densities and molecular masses of different components, the mixed gas in the gas storage cylinder stored for a long time will appear stratified. It needs to be shaken by special mixing and shaking equipment before use, which increases the cost of use, and the shaking effect cannot be guaranteed

Embodiment
[0060] The device inflates two gas cylinders 43 simultaneously at the inflation moment. Firstly, the weighing plate 44 is drawn out along the chute 451, the gas storage bottle 43 is put into the fixed sleeve 441, and then the weighing plate 44 is moved into the protective chamber 411 along the chute 451, and the two inflatable heads 421 and the gas storage bottle 43 are respectively Connected, and then close the cover 46. The vaporizer 13 is controlled by the control center 22 to change the different types of liquid gas in the two liquid tanks 11 into a gaseous state, and the gas is sent to the dual-channel air pump 21 through the two first delivery pipes 14, and the two-channel air pump 21 has two sets of The independent inflatable assembly can respectively send two different gases into the switching valve 31 through the second delivery pipe 24 . The two gases enter the first delivery channel 311 and the second delivery channel 312 respectively.

The invention relates to the technical field of mixed gas filling, and particularly relates to an automatic mixed gas filling method and filling equipment thereof. According to a switching mechanism designed by the invention, a first valve body and a second valve body are designed, the first valve body and the second valve body can be driven to act at the same time through one electromagnet, so that gas passage switching in the inflation process of two types of gas is completed, and the overall structure is simple and compact. A Y-pipe, a first gas pipe, a second gas pipe and a third gas pipe are designed in a designed gas storage bottle, a gas hole is formed at the bottom of each gas pipe, an opening of the first gas hole close to the upper portion is obliquely upward, an opening of the second gas hole close to the middle is horizontal, and an opening of the third gas hole close to the bottom is obliquely downward, thereby ensuring that in the gas filling process, the gas can be uniformly dispersed in the gas storage bottle and is uniformly mixed. Meanwhile, when the mixed gas is layered due to different densities after long-time storage, the gas in the bottle can be guaranteed to be mixed in the Y-pipe and then discharged out of the bottle, so that the practicability is enhanced.
Description
technical field [0001] The invention relates to the technical field of mixed gas filling, in particular to a mixed gas automatic filling method and filling equipment thereof. Background technique [0002] In reality, there are many gas storage equipment that need to store a variety of mixed gases, but most of the existing inflatable equipment mixes multiple gases before inflating, and then fills the mixed gas into the gas storage bottle. The gas mixing device leads to a complex structure of the inflatable equipment and a high failure rate. After the inflation is completed, due to the different gas densities and molecular masses of different components, the mixed gas in the gas storage cylinder stored for a long time will appear stratified. It needs to be shaken by special mixing and shaking equipment before use, which increases the cost of use, and the shaking effect cannot be guaranteed. Therefore, it is necessary to design an inflatable device that can realize gas mixing ...
