Medical gas pipeline through walls, floors and building foundations, should be set up sleeves, the sleeves should wear a floor above the floor surface of at least 50mm. Endo casing medical gas pipeline may not have welds should be used for medical gas pipeline noncombustible material tamped medical room should be equipotential ground between the casing and medical gas pipeline; bus medical gas switching device each decompression export, port and pipeline safety relief center oxygen outlet oxygen fast, anti-static grounding should be done; medical gas pipeline should not be more than 80 meters distance between the ground and should not be less than one, outdoor buried ends of medical gas piping should There are ground; in addition to the potential uses such as ground outside the ground should be independent, the grounding resistance should be greater than 10 ohms store liquid oxygen must be insulated, so the liquid oxygen tank has a liner, insulation (or vacuum layer), shell. Although insulation layer, oxygen can not maintain the temperature. Liquid oxygen tank material is thin, thinner than many oxygen cylinders, so there must be deflated pipes and valves. After gassing, oxygen away the heat, to insulation purposes. It's like 100 degrees to boil water to maintain the same. But sometimes they make too few calories oxygen tank pressure is too low, so there must be heated and pressurized valve circuit. Convection heating circuit by oxygen oxygen bus to work in the center, no pump, as long as the outside to the center of the heat introduced oxygen, liquid oxygen boiling point of -183 ℃. As a liquid oxygen tank on the complexity of the central oxygen supply oxygen, there must be protection frame, pressure gauges. Liquid oxygen tank valve can be automatically closed, but the booster valve can not be closed automatically, which can be used to the regulator. Central oxygen supply oxygen tank | Center gas (certified) | central oxygen supply provided by the Medical Engineering Co., Ltd. Hebei Ericsson. Ericsson Hebei Medical Engineering Co., Ltd.
