Valve designing and experiment of the single conical shell valve piezoelectric pump

Valve's following-up movement has been a tough problem for the tradition valve possess piezoelectric pump. So studying the valve is needed. By this way it may support some useful information to make a further exploring of whether can regulate pump's output by changing valve's structure and material type. In order to find the effect that applied on the single conical shell valve pump. Valve's Stress distribution has been analyzed. And valve's kinematics model has also been set up. On these bases the relationship between the valve's bending deformation and the valve's parameter such as stiffness, quality etc has been got. Finally experiments has been implemented and proving the corresponding theoretical analysis. As the valve's parameter has been chosen reasonable the pump's working output is going to be 56 Hz in working frequency and the flow rate can reach 190 ml/min under the voltage sat as 220V.
