气动逻辑元件是一种新型控制元件,它用压缩空气作工作介质,通过元件内部的运动件的动作改变气流方向来实现各种逻辑功能。除了具有一般气动用阀的优点(如抗污染能力强,对气源净化要求低,系统的输入输出装置具有统一性,不需要中间介质转换等)外,气动逻 Pneumatic logic elements are a new type of control element that uses compressed air as a working medium and changes the direction of air flow through the action of moving parts inside the element to achieve a variety of logic functions. In addition to the general advantages of pneumatic valves (such as anti-pollution ability, low requirements on gas purification, the system has a unified input and output devices, without intermediate media conversion, etc.), the pneumatic logic
