影响ASCO电磁阀技术发展的因素资料有哪些？
ASCO电磁阀中的密封部件防止介质泄露的强弱能力称为电磁阀的密封。在选购电磁阀的时候，密封性作为项技术参数也是重要的选型依据之。般意义上我们说电磁阀的密封部件主要就是指的是阀杆和填料函配合处，阀盖和阀体连接的地方、启闭件和阀座两密封面连接处。平时我们经常会说到内漏和外漏现象，外漏通常就是前两种密封部位泄露，内漏就是zui后种情况的泄露，说白了内漏就是关不严，外漏就是介质由阀内泄露到阀外了。两种泄露情况都很影响电磁阀的工作，甚有时候会发生事故。内漏主要是影响阀门截断介质的能力，所以在截断阀中，内漏与否是判断阀好坏的个重要标准。外漏则会导致介质的浪费以及污染环境。尤其是当介质是有毒性、有放射性或者易燃易爆的时候，外漏就是明令禁止的，所以此类电磁阀的选择更是关重要，必须要求有的密封。
ASCO电磁阀作为自动化仪表的种执行器，近年来用量急剧上升。本文分析了ASCO电磁阀的主要特点，并侧重应用的角度对国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ASCO电磁阀技术发展的社会因素作点探讨。 (1)外漏堵，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。电动阀力矩控制 不易，容易产生内漏，甚拉断阀杆头部；ASCO电磁阀的结构型式容易控制内泄漏，直降为零。所以，ASCO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，ASCO电磁阀的就更加。 (3)动作快递，功率微小，外形轻巧。 ASCO电磁阀响应时间可以短几个毫秒，即使是导式ASCO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，平时点也不耗电。ASCO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.
