【摘要】 针对当前气体压电阀普遍存在的工作压力低、输出流量小的问题,设计了一种基于压电堆驱动器的喷嘴挡板式控制阀,对控制阀的柔性铰链挡板进行了设计和动力学分析,对阀的最大流量作了估算。最后进行了实验研究,结果表明:所设计的压电阀响应较快、允许工作压力高、输出流量大。更多还原

【Abstract】 Aiming at the problems of low working pressure and small output flux in gas piezoelectric valve,a nozzle flapper valve based on piezoelectric stacks was designed.The flexure hinge flapper was designed and dynamic analysis was performed,and the maximum flux was evaluated.Some experimental investigation was performed.The results show the designed valve has the characteristic of faster response,high working pressure and large output flux.更多还原
