Low Temperature Valve Airtightness Experiment Cryogenic Valve
Experimental Equipment
Product description
Cryogenic treatment refers to a method in which liquid nitrogen is
used as a refrigerant to treat workpieces at a temperature below
-130°C. Cryogenic treatment can significantly improve the toughness
of the workpiece without reducing the strength and hardness of the
workpiece. Cryogenic treatment methods are divided into liquid
method and gas method. The liquid method is to put the workpiece
directly into liquid nitrogen, and the processing temperature is
-150℃. The disadvantage is that the thermal shock is large, and
sometimes even causes the workpiece to crack; the gas method is to
cool by the latent heat of vaporization of liquid nitrogen and the
endothermic heat of low-temperature nitrogen, and the processing
temperature Up to -196℃, the treatment effect is better.
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

Why take cryogenic treatment of the workpiece?
* To improve the hardness and strength of workpiece* To improve the abrasion resistance of workpiece
* To improve the impact toughness* To improve the fatigue strength
* To improve the corrosion resistance of workpiece
* To improve the internal stress distribution of workpiece
* To ensure the dimension accuracy of workpiece
