Abstract

The invention relates to a son-mother gas filling station, which consists of a compressor or a low-temperature pump, a trailer cylinder and a gas filling machine. The son-mother gas filling station is technically characterized in that the compressor or the low-temperature pump increases outlet pressure to fill gas into the trailer cylinder, so that the pressure in the trailer cylinder is higher than the pressure in a vehicle cylinder, and the gas filling for the vehicle cylinder is completed through connection with the gas filling machine. The technical scheme greatly simplifies the technological flow, and is simple, efficient, energy-saving and safer. The terminal gas filling part of the son-mother gas filling station requires no power-driven power supply or transformer, thereby saving the labor and the cost of power consumption, and the gas filling terminal (son station) part can be easily constructed; the area directly occupied by the equipment is small, and the son station expanding speed is high; the investment in large-scale equipment such as a compressor leveling body, a hydraulic leveling body and the like is saved; the zero pollution and zero emission are realized; and the gas filling capability can be easily enhanced, and the invention avoids the problems of power consumption of the son station, mechanical wear and the like in the prior art. The gas filling terminal part of the son-mother gas filling station can fill gas into the vehicle cylinder in any place in a movable or fixed way.

Description

technical field [0001] The mother-to-child gas filling station involved in the present invention is composed of a compressor or a cryopump, a trailer gas cylinder, and a gas filling machine, also known as a gas filling system, which is suitable for various gases, such as natural gas, hydrogen, etc., and belongs to the field of supporting supply of energy infrastructure equipment . Background technique [0002] In order to refuel natural gas and hydrogen fueled vehicles, a sales network is currently formed in the form of "child-mother refueling stations" to refuel automobile cylinders. The present invention is illustrated by taking a natural gas fueled vehicle as an example, and is also applicable to hydrogen. [0003] The parent gas filling station takes gas from the natural gas pipeline, adjusts the pressure, measures, dehydrates and filters it, and then enters the compressor to boost the pressure to fill the gas cylinder of the luck trailer. [0004] Another form of pare...
