LN Valve Test Cryo Storage Industries 1050kg 5 Cubic Deep Very Low Temperature Freezer ODM

Cryogenic Valve Liquid Nitrogen Cryogenic Test Cryogenic Valve Experimental Equipment

Product description

Steps

1 Place the parts evenly in the low-temperature cold box;

2 Connect the connecting pipe of the low-temperature liquid nitrogen storage tank or tank truck, pay attention to fixing, and prevent the filling liquid nitrogen from falling off or flying out and causing injury;

3 Use liquid nitrogen to immerse all the processed parts, if insufficient due to volatilization, liquid nitrogen must be supplemented;

4 According to the size and wall thickness of the parts, soak until the temperature of each part is stable, and use thermocouple measurement to ensure the uniformity of the temperature of each part of the part;

5 According to the relevant requirements of 3.1, the continuous heat preservation time meets the requirements;

6 After the parts are taken out with special tools and restored to the ambient temperature, they are repeatedly put into the liquid nitrogen cold box according to the requirements of 3.2.3-3.2.5, and the secondary treatment is performed again;

7 Take out the parts again with special tools and restore them to the ambient temperature; 3.2.8 After the low temperature treatment is over, follow-up processing can be carried out.

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
