Storage of liquid oxygen
Storage of liquid oxygen must be insulated, so the liquid oxygen tank has an inner tank, an insulation layer (or vacuum layer), and an outer shell.
Storage of liquid oxygen must be insulated, so the liquid oxygen tank has an inner tank, an insulation layer (or vacuum layer), and an outer shell. Although there is an insulation layer, the liquid oxygen temperature cannot be maintained. The material of the liquid oxygen tank is thin, much thinner than the oxygen cylinder, so it must have a vent pipe and valve. After deflation, the oxygen takes away the heat to achieve the purpose of heat preservation. It’s like boiling water and keeping it at 100 degrees. But sometimes there is too little heat in the liquid oxygen and the pressure in the tank is too low, so a heating circuit and a booster valve are necessary. The heating circuit works by convection of liquid oxygen and does not require a pump. It only needs to introduce external heat. The boiling point of liquid oxygen is -183°C. In this way, the liquid oxygen tank becomes complicated and must have a protective frame, pressure gauge, etc. The safety valve of the liquid oxygen tank can automatically close, but the booster valve cannot automatically close, which can be used to regulate pressure.
