压电式射流管阀及开环控制方法

本发明为一种新型的压电式射流管阀及开环控制方法，包括控制器、超声波电机、射流管阀组件、接气盘组件、反馈元件。由于采用了超声波电机代替传统的电磁铁，有转换精度高、迟滞小、响应快、不受电磁干扰、运行平稳、工作压力高等优点。同时本发明还提出了该电气转换装置的无反馈元件的开环控制方法。

Piezoelectric-typejet pipe valve and open-loop control method

Theinvention relates to a novel piezoelectric-type jet pipe valve and an open-loopcontrol method. The piezoelectric-type jet pipe valve comprises a controller,an ultrasonic motor, a jet pipe valve assembly, a gas receiving disc assemblyand a feedback element. Due to the fact that a traditional electromagnet isreplaced with an ultrasonic motor, the novel piezoelectric jet pipe valve hasthe advantages that the conversion precision is high, hysteresis is small, responseis fast, electromagnetic interference is avoided, operation is smooth andsteady, and the working pressure is high. Meanwhile, the invention furtherprovides the open-loop control method of an electrical conversion devicewithout a feedback element.
