Cryogenic Valve Test Experimental Equipment Cryogenic Treatment Equipment
Product description
Cold treatment and scope of applicable parts It is a treatment method to immerse the parts in a low-temperature liquid nitrogen tank for a certain period of time to reduce the deformation caused by the temperature difference and the change of the metallographic structure, thereby improving the sealing performance of the valve at low temperatures.
For cryogenic valves below -100°C, the valve body, valve cover, valve disc, valve seat, valve stem and other parts should be cryogenically treated before finishing, that is, the parts are immersed in a liquid nitrogen tank for cooling. When the temperature of the parts reaches -196°C, start to keep it warm for 1-2h, and then take it out of the box and return to normal temperature naturally.
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
