| Abstract: | A new high-speed on-off valve structure is developed by employing great force-output-impact characteristic of the piezoelectric actuator in the article, in order to overcome its disadvantages of low output deflection and sensitivity to temperature rising. The dynamic mathematic model of the piezoelectric valve is given, and a simulation is carried out. The perform of high pressure, high frequency and high flow-rate can be obtained properly according to the simulation. |
