Background
With the continuous development of national economy and the continuous improvement of industrialization, industrial equipment is rapidly developed, and the demand for gas is continuously increased. Currently, an automatic switching device is used to judge whether the gas in the steel cylinder is used or not through the pressure in the steel cylinder, and the pressure difference in the steel cylinder is utilized to switch between the cylinder and the bottle. However, there are many disadvantages to using pressure to achieve automatic switching, such as: is only suitable for switching between gas steel cylinders; if the liquid cylinder is used for switching between liquid cylinders, the liquid cylinder obtains gas by utilizing liquid volatilization, and no liquid exists in the liquid cylinder once the pressure is too low (the liquid cylinder needs to have a small amount of liquid to be reserved to achieve the effect of cold insulation because the temperature in the liquid cylinder does not rise, and a tank body needs to be cooled firstly and then filled when the liquid cylinder is refilled, so that the waste of raw material liquid and manpower is caused).
At present, the switching between gas steel cylinders is mainly realized in two ways: the first is to switch between cylinders by means of pressure difference, which causes output pressure fluctuation. The second is switching between cylinders by using the pressure in the cylinder. However, the two schemes use the liquid steel cylinders to switch, which causes waste, and no linkage device is used, which easily causes accidents.
