| titleOfInvention | A liquid nitrogen storage tank with pneumatic safety protection function |
| abstract | The application relates to a liquid nitrogen storage tank with a pneumatic safety protection function, which comprises an outer shell and an inner bladder, the inner bladder is fixedly arranged in the outer shell, a hollow structure is formed between the outer shell and the inner bladder, and a hollow structure is formed between the outer shell and the inner bladder. There is a protective cover, high-pressure gas is filled between the protective cover and the outer shell, a communication pipe is fixed on the outer shell, one end of the communication pipe is connected to the gap between the protective cover and the inner bladder, and the other end is communicated with the inner cavity of the inner bladder, and the communication pipe is provided with A valve assembly used to open the communication pipe when the air pressure between the housing and the protective sleeve decreases. When a crack appears on the outer shell of the storage tank, the high-pressure gas between the outer shell and the protective sleeve escapes, and the communication pipe is opened, so that the liquid nitrogen stored under pressure in the inner tank volatilizes nitrogen and enters between the inner tank and the protective sleeve, pushing The protective sleeve is in close contact with the inner wall of the outer shell, and the present application has the effects of improving the safety protection performance of the storage tank and the effect of thermal insulation for the liquid nitrogen in the inner tank. |
