Small liquid oxygen gas station

The invention discloses a small liquid oxygen gas station. The gas station comprises a liquid oxygen storage tank, a liquid oxygen pump and an oxygen filling platform, wherein the liquid oxygen storage tank is of a double-layer structure, a hollow structure is formed between the inner wall and the outer wall, a safety valve I, a pressure gauge I and a vacuum plug are arranged on the liquid oxygen storage tank, the safety valve I and the pressure gauge I are respectively arranged on the surface of the outer wall of the liquid oxygen storage tank, and the inner wall of the liquid oxygen storage tank is connected with external liquid oxygen by virtue of a storage tank liquid inlet valve; an exhaust valve, a liquid inlet valve and an outlet valve are arranged on the liquid oxygen pump, the liquid oxygen storage tank is connected with the liquid oxygen pump by virtue of the liquid oxygen pump liquid inlet valve, the liquid oxygen pump is connected with the oxygen filling platform by virtue of a liquid oxygen outlet valve, and an air temperature-type gasifier is arranged between the outlet valve and the oxygen filling platform; the oxygen filling platform comprises a safety valve II, a pressure gauge II, a control valve and an air inflation connector, and the safety valve II and the pressure gauge II are arranged between the air temperature-type gasifier and the control valve. The small liquid oxygen gas station can recycle cold energy and also can improve pressure in the liquid oxygen storage tank, liquid oxygen in the storage tank can conveniently enter the liquid oxygen pump, and the working efficiency of the liquid oxygen gas station can be effectively improved.
