Bottled combustible gas residual liquid recovering device

The utility model relates to a bottled combustible gas residual liquid recovering device. Parts such as residual liquid outlet valve (1), a residual liquid return valve (2), a residual liquid outlet main valve (3), a residual liquid gas bottle angle valve (4), a gas bottle (5) with residual liquid, a pressure gauge (6), a compressor (7), a residue-collecting inlet valve (8), a return outlet valve (9), a gas bottle liquid phase inlet angle valve (10), a gas bottle gas phase outlet angle valve (11), a gas liquid double-phase residue-collecting gas bottle and the like are connected into a combustible gas residue extracting and recovering device through pipelines. The bottled combustible gas residual liquid recovering device recovers the combustible gas residual liquid in various liquefied petroleum gas bottles commonly used in the market by using the conventional liquefied petroleum gas gas-liquid double-phase steel bottle (with the volume of 119 L) groups.
