电磁阀的主要特点

The main characteristic of the electromagnetic valve

（1）漏电闭锁，漏电控制，使用安全。内部和外部泄漏的元素是不安全的。其它自动控制阀杆，通常是由电动，气动，液压控制阀芯的旋转或移动来执行。这样便解决了长期运行阀杆动密封泄漏问题;只将电磁阀被施加在壳体的电磁磁芯密封完成后，没有动态密封，所以防漏容易脱落。电动阀力矩控制不易，容易产生内漏，甚至打破阀杆头部;内的结构是容易控制的电磁阀的泄漏，直至减小到零。因此，使用一种特殊的安全性，特别适用于腐蚀性，有毒或高低温介质的电磁阀。

（2）系统简单，和电脑，价格低。电磁阀本身具有结构简单，价格低廉，与控制阀和其它种类的致动器相比，易于安装和维护。由自动控制系统更显著要简单得多，价格低很多。由于电磁阀是开关信号控制，与工控计算机连接十分方便。在今天的电脑，价格暴跌，电磁阀的优势更加明显。

（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毫秒，甚至引导式电磁阀可以在几毫秒的控制。因为它的电路，比在反应等自动控制阀更敏感的。电磁阀线圈功耗设计低，节能型产品;也可以简单地触发动作，自动保持阀位，没有电平时。电磁阀外形尺寸，节省空间已经和轻盈，美观。

（4）调节精度受限，有限的适宜的培养基。 ，电磁阀，通常只有两个状态开关阀芯是仅在这两个极限位置，不连续的调节，（试图打破了很多新的概念，而且在测试试验阶段），以使调整精度是有限的。电磁阀有更高的要求，以介质的清洁度，含有介质颗粒不适用的，必须对过滤杂质。此外，粘性介质不能适用，并应适用于中等粘度范围的特定产品相对较窄。

（5）类型多样，用途广泛。电磁阀是先天不足，优势依然突出，所以他设计了多种产品，满足不同的需求，用途非常广泛。电磁阀技术的进步也围绕着如何克服的不足，如何更好地发挥固有优势。

(1) the leakage blocking, leakage control, use safety. The elements of internal and external leakage is unsafe. Other automatic control valve stem, is usually performed by the electric, pneumatic, hydraulic control valve core rotation or movement. This will solve the long-term movement stem dynamic seal leakage problem; Only the electromagnetic valve is applied to seal in electric magnetic magnetic core of casing is completed, there is no dynamic seal, so leakage blocking off easily. Electric valve torque control is not easy, easy to produce internal leakage, even to break the stem head; Within the structure is easy to control electromagnetic valve leakage, until reduced to zero. So, electromagnetic valve using a special security, especially suitable for corrosive, toxic, or high and low temperature medium.

(2) the system is simple, and the computer, prices are low. Electromagnetic valve itself has simple structure, low price, compared with the control valve and other kinds of actuators is easy to install and maintain. More significant is composed of automatic control system is much simpler, much lower prices. Because the electromagnetic valve is switch signal control, connection with industrial control computer is very convenient. In today's computers, prices plunged, the advantage of the solenoid valve is more obvious.

(3) action express, tiny power, shape and lighter. Electromagnetic valve response time can be short as a few milliseconds, even the guiding type solenoid valve can control in a few milliseconds. Because of its circuit, more sensitive than other automatic control valve of the reaction. Design of electromagnetic valve coil power consumption is low, energy-saving products; Can also be simply trigger action, keep the valve position automatically, no electricity at ordinary times. Electromagnetic valve size shape, save a space already, and light and beautiful.

(4) adjust precision limited, limited suitable medium. , electromagnetic valve, usually only two state switch valve core is only in the two limit position, not continuous adjustment, (tries to break a lot of new conception, but also in the test trial stage) so the adjustment accuracy is limited. Solenoid valve has higher requirements to the cleanliness of medium, medium containing granular not applicable, must be filter for impurities. In addition, a viscous medium not applicable, and shall be applicable to the specific products of medium viscosity range is relatively narrow.

(5) type diversity, wide range of USES. Solenoid valve is congenitally deficient, advantage is still outstanding, so he designed a variety of products, meet the needs of different, use very extensive. Solenoid valve technology advances are also revolve around how to overcome the deficiency, how to better play to the inherent advantages.
