电磁阀作为自动化仪表的一种执行器,近年来用量急剧上升。电磁阀具有一些独特的性能。
(1)外漏堵绝,内漏易控,使用安全。
内外泄漏是危及安全的要素。其它自控阀通常将阀杆伸出,由电动、气动、液动执行机构控制阀芯的转动或移动。这都要解决长期动作阀杆动密封的外泄漏难题;唯有电磁阀是用电磁力作用于密封在隔磁套管内的铁芯完成,不存在动密封,所以外漏易堵绝。电动阀力矩控制不易,容易产生内漏,甚至拉断阀杆头部;电磁阀的结构型式容易控制内泄漏,直至降为零。所以,电磁阀使用特别安全,尤其适用于腐蚀性、有毒或高低温的介质。
(2)系统简单,便接电脑,价格低谦。
电磁阀本身结构简单,价格也低,
比起调节阀等其它种类执行器易于安装维护。更显著的是所组成的自控系统简单得多,价格要低得多。由于电磁阀是开关信号控制,与工控计算机连接十分方便。在当今电脑普及,价格大幅下降的时代,电磁阀的优势就更加明显。
(3)动作快递,功率微小,外形轻巧。
电磁阀响应时间可以短至几个毫秒, 即使是先导式电磁阀也可以控制在几十毫秒内。由于自成回路,比之其它自控阀反应更灵敏。设计得当的电磁阀线圈功率消耗很低,属节能产品;还可做到只需触发动作,自动保持阀位,平时一点也不耗电。电磁阀外形尺寸小,既节省空间,又轻巧美观。

Solenoid valve as an actuator automation in recent years, consumption increased dramatically. Solenoid valve has some unique properties.
(1) leakage blocking must, within the leak easy to control, safe.
Internal and external leaks are endangering the safety factor. Other controlled valve stem out usually by electrical, pneumatic, hydraulic actuator control valve of the rotation or move. This should solve the long-term action outside the dynamic seal valve stem leakage problems; only solenoid valve is electromagnetic force on the sealed compartment within the magnetic core casing complete, there is no dynamic seal, so easy to block leakage must. Electric torque control valve is not easy, prone to internal leakage, and even pull off the stem head; solenoid valve within the structure of type easy to control leakage, until reduced to zero. Therefore, the use of special safety valve, particularly suitable for corrosive, toxic or high temperature media.
(2) system is simple, then take the computer, low price modest.
Solenoid valve itself is simple, the price is also low, compared to control valve actuators, and other types of easy installation and maintenance. More significant is the automatic control system consisting of much simpler, much lower price. As the solenoid valve is a switch signal control, and industrial computer connection is very convenient. In today's widespread use of computers, an era of declining prices, the electromagnetic valve is even more obvious advantages.
(3) action express, power tiny,
lightweight form factor.
Valve response time can be as short as a few milliseconds, even pilot-type solenoid valve can be controlled in several milliseconds. As the self into a loop, other than the automatic control valve more responsive. The proper design of solenoid valve coil power consumption is very low, is energy-saving products; can do just trigger action, automatically maintain the valve position, usually is not power. Solenoid valve shape, small size, both to save space, and lightweight appearance.
