How to output liquid nitrogen from a liquid nitrogen tank, there are three methods: self-pressurized liquid nitrogen tank
How to output liquid nitrogen from a liquid nitrogen tank, there are three methods: self-pressurized liquid nitrogen tank
1. Directly pour out liquid nitrogen:
Generally, small liquid nitrogen tanks can be directly poured out from liquid nitrogen tanks. However, this method should be careful that liquid nitrogen is spilled onto the skin to cause frostbite. Large liquid nitrogen tanks are difficult to operate by one person and need to be pressed by a pressure device (liquid nitrogen pump). The liquid nitrogen is pressed out, and the liquid nitrogen pump is used as follows:
2. Liquid nitrogen pump:
Close the liquid nitrogen pump outlet valve (rotate clockwise, tighten), insert the liquid nitrogen pump into the liquid nitrogen tank, and rotate the lock nut in a timely direction so that the seal seals the liquid nitrogen pump and the neck of the container. (Hand tightening); otherwise, the liquid nitrogen pump can be taken out of the liquid nitrogen container.
With the foot pump on the air several times, liquid nitrogen can flow out.
Note: This device can only be used on cans with a diameter of 50mm.

3. Infusion through self-pressurized liquid nitrogen tank:
(1), close the vent valve; (2) open the booster valve; (3) observe the pressure gauge; (4) when the pressure rises to 0.05 MPa (0.5 kg/cm2) (or when the required operating pressure is reached) ), open the liquid outlet valve for continuous infusion.
Principle: The pressure is generated by vaporization of a small amount of liquid nitrogen in the tank, so that the container can automatically discharge liquid nitrogen, thereby supplementing other containers with liquid nitrogen.
The above is a commonly used method for pouring liquid nitrogen from a liquid nitrogen tank. Hope can help you

Special Note:
1. Liquid nitrogen is a liquid gas at minus 196 °C. Contact with bare skin can cause personal injury and can also cause breakage of common materials such as plastics, carbon steel and rubber; therefore, be careful when using liquid nitrogen tanks.
2, in order to store liquid nitrogen for a long time, generally stored in the specified liquid nitrogen container, do not use household vacuum bottles or other vacuum flasks. Unsuitable containers may freeze or spill liquid nitrogen, causing unnecessary damage. Self-pressurized liquid nitrogen tank
