The invention discloses an oxygen tank-filling system for an airport. The oxygen tank-filling system comprises an oxygen cylinder group, a first valve, a pressure reducing valve, an oxygen compressorand a second valve which sequentially communicate with each other through pipelines, and further comprises a third valve and a fourth valve. The first end of the second valve communicates to a gas outlet of the oxygen compressor through a pipeline, when external gas using equipment is oxygenated, the second end of the second valve communicates to the gas using equipment through a pipeline, the first end of the third valve communicates to the pipeline between the first valve and the pressure reducing valve through a pipeline, when the oxygen cylinder group is oxygenated, the second end of the third valve communicates to an external oxygen source through a pipeline, the first end of the fourth valve communicates to the pipeline between the oxygen cylinder group and the first valve through apipeline, and the second end of the fourth valve communicates to the pipeline between the oxygen compressor and the second valve through a pipeline. The oxygen tank-filling system has the advantages that the oxygen tank-filling system for the airport is simple in overall structure, convenient to operate and low in cost.
Description
technical field [0001] The invention relates to the field of gas tank filling, in particular to an oxygen tank filling system for airports. Background technique [0002] Aircraft, whether they are civil aviation or military aircraft, need to supply oxygen to the driver and passengers. Most of the existing technologies use liquid oxygen and liquid pumps to fill high-pressure oxygen, and the oxygenation car is a way to transfer the oxygen stored on the ground to the aircraft. The special vehicle used by the crew on board uses the oxygen booster compressor as the main engine, and at the same time integrates the oxygen supply system, filling system, gas storage cylinder group and electrical control equipment into one, and can be easily moved. Filling device, but in the prior art, the airport oxygen tank filling system has complex structure, inconvenient operation and high cost. Contents of the invention [0003] The technical problem to be solved by the invention is: the prob...
