摘　　要：综述了电／气阀门定位器、转换器核心部件——电／气转换装置的工作原理及国内外研究现状，着重介绍了一种利用压电复合圆盘为挡板的新结构电／气转换装置，该装置在较低电压下就可以满足输出气压0．02～O．10MPa的工业现场要求。The paper introduced the operating principles, research achievements and developing trends about electric-pneumatic transfer device,which is the most important accessory section of positioner and transducer. And a new electric-pneumatic transfer device based on piezoelectric composite disc actuator as the nozzle/flapper was presented. The new device can meet the requirements of air pressure output between 0.02 and 0.1MPa in industrial areas with low voltage.
