Primary Study of Supercritical Helium Heating Pressurization Scheme

介绍了超临界氦加温增压系统的工作原理 ,系统中液氦贮瓶、氦加温器、几个极低温阀的用途 ,并介绍了液氦贮瓶使用中的 4个关键因素和液氦贮瓶系统的试验项目。对于增压排放液氦所需常温氦气用量计算、液氦贮瓶内温度和压力随时间的变化计算也做了简要介绍。

The system working principle and the uses of liquid helium storage bottle, helium heater and some hyper cryogenic valves are presented in this paper. The test items of liquid helium storage bottle and the four key factors while using liquid helium storage bottle are introduced. The calculations of normal temperature helium consumption for the liquid helium pressing discharge and the variation of temperature and pressure in the liquid helium storage bottle developing with time are also introduced in brief. In the end merits and demerits of supercritical helium heating pressurization scheme are analyzed.
