Technical Field

[0001] The utility model relates to the technical field of liquefied gas recovery equipment, in particular to a residual gas recovery device in a liquefied gas pipe. Background Art

[0002] When the existing household liquefied gas cylinder is in use, the switch valve of the liquefied gas cylinder is connected to the gas stove through a connecting hose. After use, the switch valve of the liquefied gas cylinder is generally closed directly after the fire is turned off. After the switch valve is closed, a part of the gas will remain in the connecting hose between the switch valve and the gas stove. If it is not recovered, it will cause a certain amount of waste. Therefore, we have introduced a new residual gas recovery device in the liquefied gas pipe. Utility Model Content
