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
