Inflation connecting device with recovery function

The utility model belongs to the field of gas pipeline systems, and particularly relates to an inflation connecting device with a recovery function. The inflation connecting device with the recovery function comprises a liquid inlet recovery interface, an inflation interface and an inflation pipeline connected between the liquid inlet recovery interface and the inflation interface, and further comprises a storage interface and a recovery pipeline connected between the liquid inlet recovery interface and the storage interface, and a compressor is arranged on the recovery pipeline. According to the utility model, the gasification device on the gas filling pipeline is used for gasifying inlet liquid such as sulfur hexafluoride, so that the gasification speed and the gas filling speed are improved; and gas in the gas chamber is recycled through the compressor on the recycling pipeline, and the gas recycling function is achieved. The inlet liquid recovery interface can be rapidly connected with a gas cylinder (inf
