The invention discloses an LNG (Liquefied Natural Gas) refueling station composed of one pump band and multiple gas dispersers. The LNG refueling station is composed of a low-temperature storage tank, a low-temperature pump and multiple gas dispersers. The LNG refueling station is technically characterized in that the liquid outlet of the low-temperature storage tank is connected with the liquid inlet of the low-temperature pump; the gas phase opening of the low-temperature storage tan is connected with that of the low-temperature pump; the liquid outlet of the low-temperature pump is connected with upper and lower liquid phase inlets of the low-temperature storage tank or one of liquid and gas phase openings through valves; the liquid outlet of the low-temperature pump is in parallel connected with the liquid inlets of the multiple gas dispersers through valves; the liquid outlets (return air inlets) of the multiple gas dispersers are respectively connected with upper and lower liquid inlets of the low-temperature storage tank or one of the liquid and gas phases of the low-temperature storage tank; pipelines with a one-way valve is connected in parallel between the upper and lower liquid inlets of the low-temperature storage tank or one of the liquid and gas phases and the liquid inlets of the multiple gas dispersers respectively.
