工业过程控制系统用电磁阀的分类与选型研究

Research on Classification and Selection of Solenoid Valve for Industrial Process Control System

电磁阀具有结构简单、体积小、可靠性高、操作方便、使用寿命长、污染少、抗干扰能力强以及易实现自控性和智能化等优点,在工业领域得到了广泛应用。电磁继电器的功能相当于一个开关,当它开启的时候会有一定的延时,而延时的时间决定着这个延时的长短和速度。当前工业系统中电磁阀的类型具有多样性,需要对其分类与选型进行研究。

Solenoid valve has the advantages of simple structure,small volume,high reliability,convenient operation,long service life,less pollution,strong anti-interference ability,easy to achieve self-control and intelligence,etc.,and has been widely used and promoted in the industrial field.The function of electromagnetic relay is equivalent to a switch.When it is opened,there will be a certain delay time,and the delay time determines the length and speed of the delay.Now the type of solenoid valve in the industrial system is more diversified,which needs to study its classification and selection.
