摘要
本文介绍了分析规模超临界萃取装置限流器的发展趋势,并详细介绍了一种新型限流器的设计。该限流器通过给阀体控温加热,彻底解决了超,临界萃取中的冰堵问题。限流器采用两组阀结构,延长了限流器的使用寿命。
The trends of restrictor for analytical scale super critical fluid extraction equipment and design of a new restrictor were introduced. The restrictor solved the ＂ice block＂problem by heating the valve＇s body. The restrictor was component of two valves and prolongs its use life.
