Product introduction: vertical Dewar bottle self-pressurization liquid nitrogen tank

Low temperature Dewar bottle products, is the use of advanced technology and technology, the production process of each link in the scientific, strict quality assurance system control. It is composed of stainless steel inner and outer tank, high vacuum insulation interlayer, built-in vaporizer, valve pipeline system, etc. It is used to store and use cryogenic liquefied gas products (liquid oxygen, liquid nitrogen, liquid argon, liquefied natural gas, liquid carbon dioxide) and can automatically provide continuous gas or cryogenic liquid nitrogen.

Product introduction:

Dewar bottle, a stainless steel pressure vessel with super vacuum insulation, is designed for storage, transportation and use of liquid oxygen, liquid nitrogen, liquid argon or carbon dioxide. For reliable and economical transportation and storage of cryogenic liquid gas, as well as local storage and supply of cryogenic liquid gas in a wide range of applications. And liquid nitrogen.

Dewar bottle has two main advantages: first, it can hold a large amount of gas at relatively low pressure compared with compressed gas cylinder. The second is that it provides an easy to operate cryogenic liquid source. Third, two-way output, one output liquid nitrogen gas, the other output liquid nitrogen, can provide low-pressure refrigeration liquid liquid nitrogen for the equipment. Gas liquid two-phase use.

Dewar bottles can be used for a variety of purposes:

Direct gas supply at work site, and its use form is similar to that of compressed gas cylinder;

Small and simple centralized gas supply pipeline;

Low temperature liquid use, etc.

Advantages of Dewar bottle:

Low storage pressure, multi-stage safety protection device, better safety, and simple and reliable operation.

A large volume of nitrogen and oxygen storage cylinders. Therefore, the storage area can be reduced, the bottle changing operation can be reduced, and the work efficiency can be improved. For centralized pipeline gas supply, it can reduce bus investment.

Higher purity, cleaner gas supply. Because of the direct vaporization supply of liquid gas, it avoids the potential quality hazard caused by secondary pollution in the process of filling, transportation and use. In general, the purity of oxygen, nitrogen, argon and carbon dioxide are 99.2%, 99.999%, 99.995% and 99.9%, respectively.

High gas utilization rate: residual pressure must be reserved after each use of cylinder gas, and liquid gas supply of hexagonal cylinder can avoid any waste and reduce gas cost.

The weight of hexagonal cylinder is about 116kg, and the total weight after filling with liquid gas is about 300kg, while the total weight of compressed gas of 30 cylinders with the same amount of gas is nearly 2000 kg. Therefore, the auxiliary cost of transportation and manual handling can be greatly reduced.

Built in carburetor, high pressure control and pressure control.

Use advanced technology to improve the production environment and corporate image.

It does not need any kinetic energy and is not affected by power failure and water cut-off. It can work all day long.


Bander liquid nitrogen tank introduces self pressurized liquid nitrogen tank to you
 
The self pressurized liquid nitrogen tank is made of stainless steel with liquid nitrogen pressure output, and the overall self pressurized liquid nitrogen tank is made of stainless steel. The main principle is to vaporize a small amount of liquid nitrogen in the tank by opening the pressurization valve of the tank
So as to increase the pressure in the tank. When the output critical pressure is reached in the tank, the liquid nitrogen can be discharged normally by opening the drain valve. It can be used as ultra-low temperature refrigeration source for other test instruments and equipment, or storage type liquid nitrogen tank and large

Liquid nitrogen tank Portable liquid nitrogen tank as liquid nitrogen supplement. The self pressurized liquid nitrogen tank is also very suitable for transportation of liquid nitrogen. The volatilization of liquid nitrogen during long-term transportation and storage is very low. It can also store liquid argon, liquid oxygen, and other liquid gases

 
Structure of self pressurized liquid nitrogen tank
The self pressurized liquid nitrogen tank is composed of self pressurized liquid nitrogen tank body, valve, assembly, neck, liquid outlet, exhaust port, booster pipe, neck level gauge, lower caster and internal pressurized coil
 
Use of self pressurized liquid nitrogen tank:
 
The first choice is to fill the empty self pressurized liquid nitrogen tank with liquid nitrogen. Open the vent valve and inlet and outlet valve, connect the inlet and outlet valve, and fill the tank with liquid nitrogen. Observe the vent valve and pressure gauge. When the pressure gauge is overpressured, the pressure relief valve will release pressure
When the liquid nitrogen is discharged from the vent valve, look at the liquid level gauge at the neck. The top of the liquid level gauge indicates that the tank is full of liquid nitrogen. At this time, the filling of liquid nitrogen is finished.
2. When the liquid nitrogen tank is placed at high pressure, the internal pressure of the newly filled self pressurized liquid nitrogen tank is high, and the pressure relief valve will release the pressure regularly. You can directly open the vent valve to release air and release the internal pressure. Let the self pressurized liquid nitrogen tank stand still directly
It can also be placed regardless of state. When using, according to the pressure used, release the pressure and adjust to the use pressure.
3. Pressurization: open the booster valve slowly every time you use it. Do not increase the pressure to the end at one time. When the pressure exceeds 0.05Mpa, you can start to open the drain port to output liquid nitrogen. This also depends on the final pressure situation used by the user.
After use, you can open the vent valve to release the pressure inside.
4. The observation of liquid level gauge is from the liquid nitrogen in the pressurized liquid nitrogen tank. When using the liquid level gauge, do not wait until the liquid level gauge reaches the bottom before filling liquid nitrogen, which will seriously affect the life of the tank. When there's some liquid nitrogen left
Fill in liquid nitrogen.
5 self pressurized liquid nitrogen tank Portable liquid nitrogen tank and liquid nitrogen containers Stainless steel metal hose should be connected to make up liquid nitrogen.

Bande liquid nitrogen tank series products provide one year free after-sales service
Five year vacuum warranty.
