Because of the shortage of related research,active valve,as the key composing part of piezoelectric pump, had very important influence on the performance of piezoelectric pump,a new type of active valve actuated by circular piezoelectric bimorph was developed. First, active vavle based on the circular piezoelectric bimorph was designed, and the working principle of the valve was analyzed.Then,the structure model of the valve body was set up, the flow formula of the valve was established,the optimization of the structure parameter was carried out by using ANSYS software,the optimization parameter including the valve aperture of 0.3mm、the valve width of 0.5mm、the valve radius of 0.7mm were obtained. Finally, active valve was manufactured and the relevant experiment study were carried out, the experimental results showed the active valve had the maximun flow of 540ml/min, and the flow of vavle could be adjusted by changing square wave duty-cycle. The structure model and experiment results provided theoretic fundation for the structure design of valve body with the active valve.
