Information
  1. Vacuum insulation is adopted for the low-temperature storage tank, and the insulation material is pearlescent sand.
  
  2. The top liquid is designed with a porous shower structure, which can make the low-temperature liquid stable when it is filled into the inner container. And can make part of the gas phase in the inner vessel absorbed and liquefied at low temperature to maintain the relative stability of the gas pressure of the inner vessel during the filling process.
  
  3. The support structure between the inner tank and the outer shell adopts the upper stainless steel pull belt and the lower stainless steel tube support. Under the normal working position of the equipment (vertical), the gravity load of the liner and its storage medium is transmitted to the casing through 3 stainless steel pipes, and finally to the casing legs and equipment foundation, to avoid the generation of additional eccentric moment load, the structure At the same time, the need to freely contract the liner under low temperature conditions during equipment operation is guaranteed.
  
  4. The low-temperature pipeline is led out from the lower end of the tank, which is convenient for operation and maintenance. In order to ensure that the tank can stably and safely store low-temperature liquids, the tank is equipped with multiple safety devices and instruments: equipped with a liquid level gauge, a pressure gauge, an outer cylinder explosion-proof device in the interlayer, a combined safety system in the inner tank, and a pipeline Safety valve, etc.
