Integrated valve for automatic gas-liquid switching output of low-temperature liquid container

The invention relates to the technical field of valves, in particular to an integrated valve for automatic gas-liquid switching output of a low-temperature liquid container, which comprises a gas driving valve and a switching assembly, the gas driving valve comprises a main valve body internally provided with a liquid channel and a gas channel, a driving piece internally provided with an expansion cavity, a first valve element, a second valve element, a connecting assembly and an elastic piece. The driving part can extend along with the increase of the pressure of the expansion cavity, and the switching assembly connects the expansion cavity with the air inlet channel, so that the pressure of the expansion cavity changes along with the pressure change of the air inlet channel; the first valve element and the second valve element are connected through a connecting assembly, the connecting assembly is connected with the telescopic end of the driving part, so that the first valve element and the second valve ele
