The liquid nitrogen supply series is mainly used for storing liquid nitrogen in large liquid nitrogen tanks. The low-temperature liquid nitrogen medium storage container with high performance uses the vaporization of a small amount of liquid in the container to generate pressure, so that the container automatically discharges the liquid, so as to supplement the liquid nitrogen for other containers. This series of products are fully equipped with safety structures such as booster valve, drain valve, drain valve, pressure gauge, etc., to serve laboratory users and chemical enterprise users for liquid nitrogen storage or liquid nitrogen automatic replenishment.
