    Poster

    A 1.8K superfluid 4He system could be used in many cryogenic devices, such as the separation of helium isotopes and the advanced superconducting accelerator. Cryogenic stop valve is one of the most important part of the 1.8K system. Simulation studies on heat transfer were made by ANSYS. According to the simulated data, the heat loss was reduced by 60% when the double heat sinks were welded...

    Poster

    In the development process of cryogenic valves, liquid nitrogen is usually used as the cooling medium to carry out relevant performance tests. When the temperature is lower than 77 K, for example, for liquid hydrogen valves, expensive liquid helium is usually used as the cooling medium due to safety concerns. In this paper, a cryogenic test equipment is designed to test the take-off...

    Abstract. Cryogenic valve sealing technology is notoriously more challenging than traditional fluids due to the combination of small atoms and molecules with extreme temperature and pressure profiles. Recently, flexible polymeric films folded into origami demonstrated considerable resilience to mechanical failure in the cryogenic extreme. Showing that thin, fluorinated polymers such as...

  4. 663. C1Po1B-05: A novel lightweight cryogenic valve with minimized heat transfer

    Poster

    Industrial valves for cryogenic application are typically made of austenitic stainless steel. A new design has been developed, where stem and extended bonnet are made of glass fiber reinforced PEEK (PEEK/GF). This material has a significant lower heat conductivity and lower specific weight. Therefore valves with minimized heat input as well as very compact and lightweight valves can be...
