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
