Paper Abstract

Electric-pneumatic transducer and electric-pneumatic positional valve has advantages of fire protection, explosion protection and lifetime dilatation etc, and are widely used in industrial automatic production. In this paper, two new electric-pneumatic transfer device with piezoelectric actuator whose structure and operating principle are proposed. One is based on the principle of nozzle-flapper, the other is based on opening-closing. Experiment research was carried on and the results show that the new transfer devices can meet requirement of air pressure output between 0.02MPa and 0.1MPa in industrial field with low voltage, which provides good basis of development of electric-pneumatic transducer valve with new piezoelectric structure.
