High Reliability Liquid Cryogenic Dewar Cylinder
High Reliability Manufactured Dewar Bottle Liquid Cryogenic Dewar Cylinder
Dewars, also known as thermos flasks, are ideal containers and tools for storing liquid gases, cryogenic research and crystal element protection.
The structure of the dewar flask
Gas cylinder liner In order to ensure that the inner liner of the gas cylinder is below the safe pressure, a safety valve and a rupture disk are installed on the gas cylinder. Protective ring The upper part of each insulated cylinder has a stainless steel ring structure (protection ring) to protect the pipeline. The protection ring is connected to the cylinder by four brackets, and each bracket is slotted to facilitate the use of trolleys and cranes to transport gas cylinders.

1. Store pure low temperature liquid. The storage gas volume is large. The gas storage capacity of a DP175 Dewar is equivalent to more than 18 times the gas storage capacity of a standard high-pressure gas cylinder.
2. The internal pressure of the gas cylinder will rise during the deactivation stage after being filled with liquid. The gas cylinder has a high-performance adiabatic system, and its pressure rise rate is low. Usually, it is not necessary to reduce the pressure through a safety valve.
3. The built-in supercharger and vaporizer can realize continuous supply of gas or liquid, and no external vaporizer is required under the designed dosage.
