摘要
以"0、1"组合的数字信号作为数控电动阀的执行信号,以红外传感器、球阀、7字形电机、电机驱动电路为硬件核心,完成了数控电动阀门的位置检测、阀门电机驱动与信号传输电路等电路设计。采用红外传感器反馈阀门开合状态的控制方式,对球阀开度进行控制,进而对管道内的流动液体实现一定范围内的流速与流量控制,经试验测定表明此电动阀门装置集成度高、控制灵活、结构简单,可操控性强,适合工农业和科研实验室的流速与流量控制使用。
Digital signal ＂0、1＂ as a combination of numerical performing signal electric valve, infrared sensors, ball-shaped motor 7, the motor drive circuit as the hardware core, the position detection is completed NC electric valve, and the valve motor drive transmission signal circuit design circuit. Infrared sensor feedback valve open and close state control of the valve opening is controlled, and then the flow of fluid within the pipe to achieve a flow rate and flow control within a certain range, the test indicates that the measured electric valve device is highly integrated, flexible control simple structure, maneuverability, suitable for industry, agriculture and research laboratories velocity and flow control use.
