220V Cryogenic Valve Experimental Equipment 600kg Liquid Nitrogen Chest Freezer 1 Ohm

Cryogenic Treatment Of Main Parts Of Cryogenic Valve Experimental Equipment

Product description

The main parts of the cryogenic valve are treated at low temperature and each batch is sampled for low temperature impact test to ensure that the valve is not brittle under low temperature conditions and can withstand the impact of low temperature media.
Perform the following tests on each valve:
1. Normal temperature shell strength test;
2. Normal temperature and low pressure upper sealing test;
3. Normal temperature and low pressure sealing test;
4. Low temperature upper seal airtight test (when there is upper seal);
5. Low-temperature air-tightness test, etc. to ensure that the entire cryogenic valve meets the requirements of the standard;
6. Low-temperature treatment of the main parts and low-temperature impact test for each batch of samples to ensure that the valve is not brittle under low-temperature conditions and can withstand the impact of low-temperature media;
7. Low temperature (cryogenic) valves are subjected to low temperature treatment and impact test in accordance with the corresponding material specifications;
8. The electrostatic function is more powerful, and the conduction resistance between the valve body and the valve stem or the internal parts and the valve body is less than 1 ohm.

Advantage of Valve Low Temperature Equipment

1. It has extreme low temperature ,with the lowest temperature reaching -196℃,which can greatly meet the requirements of cryogenic treatment and cryogenic experiments for cryogenic valves and ultra-low temperature valves.

2. The latest intelligent temperature control system is adopted ,which can set required temperature parameters,cooling speed and heat preservation time according to process  requirements ,and has process recording and remote monitoring functions.

3. The equipment adopts advanced liquid nitrogen dispersion technology and unique cold aircirculation system,make full use of liquid nitrogen function ,and completes the air tightness test of low-temperature valve in the process of uniform,stable and rapid cooling
