摘要
本文研制了在流动注射分析及其它自动分析中应用的8状态旋转阀。该阀用步进电机驱动,光电开关定位,单片微机系统控制。所研制的阀应用于自动溶剂萃取光度分析,取得满意效果。
A multiposition valve is described in this paper,it is based on a general purpose 8 port load/inject valve,driven by a stepper motor,positioned with a photoelectric switch,and controlled by a single chip microcomputer system.The valve,rotated in 360°,has 8 positions,which enable any hole on the rotor to match all the 8 holes on the stator one by one.Therefore ,it can meet the demand for valve by some new FIA(flow injection analysis)techniques and automatic analytical methods.This valve has been employed in an automated solvent extraction method with photometric detection.
