Liquid nitrogen is a cryogenic liquid, which is widely used in industry, medical treatment, scientific research and other fields. Because of its extremely low temperature and high pressure, the storage and use of liquid nitrogen storage tanks need to be extra careful. In this paper, the details of liquid nitrogen tank and matters needing attention in use will be introduced in detail to help you better understand and use this important cryogenic container.

I. Structure of Liquid Nitrogen Tank
Liquid nitrogen tank is a metal container with double-layer structure, the inner layer is made of stainless steel or aluminum alloy, and the outer layer is usually made of carbon steel or stainless steel. The design of this double-layer structure can effectively maintain the temperature of liquid nitrogen, and at the same time prevent the invasion of external heat from causing the externalization of liquid nitrogen. The liquid nitrogen tank is also equipped with safety accessories such as safety valve, pressure gauge and liquid level gauge to ensure its safe use.
Second, the storage and use of liquid nitrogen storage tanks
1. When storing the liquid nitrogen tank, it should be placed in a well-ventilated, dry place without direct sunlight. At the same time, in order to avoid overturning or collision, the liquid nitrogen tank should be placed on a stable table or use special fixing devices.
2.
Before use, check whether the liquid nitrogen tank is in good condition, especially whether the safety accessories such as pressure gauge and safety valve work normally. If any abnormality is found, stop using it immediately, and contact professionals for maintenance in time.
3.
When injecting liquid nitrogen into the liquid nitrogen tank, the hydraulic valve force of the liquid nitrogen tank should be opened slowly. When the reading value of the pressure gauge is reached, the upward pressure lifting force should be observed. The liquid inlet valve should be closed. In the process of filling liquid nitrogen, it is forbidden to put the liquid nitrogen tank in overpressure state.
4. During use, pay attention to control the temperature in the liquid nitrogen tank, such as fruit pressure. If it is abnormal, stop using it immediately and contact a professional for maintenance.
5. When transferring liquid nitrogen, a special transfer vehicle or transfer tank should be used for operation. It is forbidden to dump liquid nitrogen directly on the ground or in a pool to avoid polluting the environment and causing personal injury.
6. After use, the liquid nitrogen tank should be placed in a safe place and properly kept. At the same time, in order to ensure safety, the pressure gauge, safety valve and other safety accessories of the liquid nitrogen tank should be regularly checked for normal operation.
