一种真空保温孔板式低温流量计用于 4米高温超导电缆制冷系统。在结构上它与真空输液管做成一体 ,焊在输液管内管上 ,没有多余的接头连接。因而有效地减少了热量损失。它具有热损小、寿命长、能工作于气液两相等优点 ,减少了系统预冷期间的诸多麻烦。介绍了低温流量计的技术要求、设计方案和应用情况
A vacuum insulation orifice plate cryogenic flowmeter for 4 m high temperature superconducting cable refrigeration system. It is structurally integrated with a vacuum infusion tube and welded to the tube inside the infusion tube without any extra splice. Thus effectively reducing the heat loss. It has small heat loss, long life, can work in the advantages of gas and liquid two, reducing the system during the pre-cooling of many troubles. The technical requirements, design scheme and application of low temperature flowmeter are introduced
