Description

Technical Field

[0001] The utility model relates to the technical field of contraction devices, in particular to a gas filling machine air pipe contraction device. Background Technique

[0002] A gas filling machine refers to a gas filling device that provides fuel to natural gas vehicles and large CNG sub-station vehicles in the form of compressed natural gas. The gas in the natural gas pipeline generally undergoes pre-purification treatment first to remove sulfur and moisture in the gas, and then the compressor unit compresses the pressure from 0.1 - 1.0 Mpa to 25 Mpa. Finally, the dispenser fills the vehicle with gas. When using the gas filling machine to add gas to a vehicle, the staff moves the gas filling gun and hangs it on the gas filling hole of the vehicle to add gas. After the gas filling is completed, when the staff puts the gas filling gun back on the gas filling machine, the gas filling pipe connected between the gas filling machine and the gas filling gun will be scattered on the ground, and a gas pipe contraction device is needed to contract and sort the gas filling pipe.
