Jianshen tank tells you the advantages of Dewar flasks

Introduction to the advantages of Dewar flasks:
 
  1. The storage pressure is low, and the multi-level safety protection device is installed, which has better safety and simple and reliable operation.
 
  2. Large storage capacity. The gas storage capacity of a hexagonal gas cylinder is equivalent to nearly 30 cylinders (oxygen, nitrogen, argon). Therefore, storage space can be reduced, bottle changing operations can be reduced, and work efficiency can be improved. For centralized gas supply in pipelines, bus investment can be reduced.
 
  3. The bottle body is clean and the supply gas purity is higher. Because the liquid gas is directly vaporized and supplied, it avoids the hidden quality hazards caused by secondary pollution due to many links in the process of filling, transporting and using cylinder gas. Usually output oxygen purity ≥99.2%, nitrogen purity ≥99.999%, argon purity ≥99.995%, carbon dioxide purity ≥99.9%.
 
  4. High gas utilization rate: After each use, the cylinder gas must have residual pressure, and the liquid gas supply of the hexagonal gas cylinder can avoid any waste and reduce the gas cost.
 
  5. The weight of the hexagonal gas cylinder is about 116Kg, and the total weight after being filled with liquid gas is about 300Kg. The total weight of the compressed gas in 30 cylinders with the same amount of gas is nearly 2000 Kg. Therefore, the auxiliary cost of transportation and manual loading and unloading can be greatly reduced.   6. With automatic pressurization control, saving circuit, built-in vaporizer, pressure and liquid level indicating device, high integration.
 
  7. Use advanced technology to improve the production environment and enhance corporate image.
 
  8. It does not need any kinetic energy, is not affected by power outages and water cuts, and can work around the clock.
 
  The external structure of the Dewar: Generally, there are four valves in the Dewar, namely, the liquid use valve, the gas use valve, the vent valve, and the booster valve. In addition, there are gas pressure gauges and level gauges. When the Dewar is stored and not in use, remember not to open the booster valve. Be sure to check whether the booster valve is closed, otherwise it will cause gas leakage in the bottle. The Dewar is a high-vacuum multi-layer insulation with a volume of 170-200L, which is convenient for the transportation and use of a small amount of cryogenic liquid. It is a new choice to replace the traditional high-pressure bottled gas transportation and use.
