Abstract: The oretical analysis and calculation are completed for valve design of micro electrostatic pumps. Taking ball valve as the focus, the difference between inlet valve and outlet valve is discussed. The relationship among the flow rate, the pressure difference between the top and bottom planes of ball plug and the area of valve tuber is given when the valve is opened, as well as the relationship among the minimum inner radius of the valve tuber, the flow rate and pressure difference. After that, the Reynolds coefficient is calculated from the radius of the valve tube and the flowing velocity, therefore the selected flow coefficient is checked. The force exerted by the ball plug on the cobweb is studied, and the strength verification of the cobweb is carried out. In addition the selection of mesh diameter  is discussed too and else wise so on.
Key words: electrostatic pump; ball valve; radius of vale tube; flow coefficient; Reynolds coefficient; impact force
