影响德FESTO电磁阀技术发展的因素主要资料有哪些
德FESTO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。本文分析了德FESTO电磁阀的主要特点，并侧重应用的角度对内成熟技术的发展动态 作简要综述，分别在精简化、智能化、通用化、化方向作了考察，并略对影响电磁阀技术发展的社会因素作点探讨。 (1)外漏堵，内漏易控，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。电动阀力矩控制 不易，容易产生内漏，甚拉断阀杆头部；德FESTO电磁阀的结构型式容易控制内泄漏，直降为零。所以，德FESTO电磁阀特别安全，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，低谦。 电磁阀本身结构简单，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，要低得多 。由于德FESTO电磁阀是开关信号控制，与工控计算机连接十分方便。在电脑普及，大幅下降的时代，德FESTO电磁阀的就更加明显。 (3)动作快递，功率微小，外形轻巧。 电磁阀响应时间可以短几个毫秒，即使是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。德FESTO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 rose sharply. This paper analyzes the main characteristics of the electromagnetic valve, dynamic development and focus on the application point of view to the domestic mature technologies are summarized, respectively, in the streamlined, inligent, universal, made a special study of the direction, and a little on the social factors that influence the development of solenoid valve technology point to explore. (1) leakage blocking must, easy to control leakage, the use of safety. Internal and external leakage is endangering the safety factor. Other automatic control valve will usually stem out from the electric, pneumatic, hydraulic actuator control valve, rotate or move. This should solve the long-term action of external dynamic seal valve stem leakage problem; only the electromagnetic solenoid valve is the use of electromagnetic force to complete sealed compartment inside the magnetic core casing, there is no dynamic seal, so easy to block leakage. Electric torque control valve is not easy, prone to internal leakage, and even pull off the stem head; structure of the solenoid valve is easy to control leakage, until reduced to zero. Therefore, the use of special safety valve, especially for corrosive, toxic or high temperature media. (2) the system is simple, they take the computer, low price and modest. Solenoid valve itself is simple, the price is low, compared to other types of valve actuator is easy to install and maintain. 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. Popular in today's computer, the era of decline in prices, the electromagnetic valve is even more obvious advantages.
