電磁閥的主要特點

The main characteristic of the electromagnetic valve

（1）漏電閉鎖，漏電控制，使用安全。內(nèi)部和外部泄漏的元素是不安全的。其它自動控制閥桿，通常是由電動，氣動，液壓控制閥芯的旋轉(zhuǎn)或移動來執(zhí)行。這樣便解決了長期運行閥桿動密封泄漏問題;只將電磁閥被施加在殼體的電磁磁芯密封完成后，沒有動態(tài)密封，所以防漏容易脫落。電動閥力矩控制不易，容易產(chǎn)生內(nèi)漏，甚至打破閥桿頭部;內(nèi)的結(jié)構(gòu)是容易控制的電磁閥的泄漏，直至減小到零。因此，使用一種特殊的安全性，特別適用于腐蝕性，有毒或高低溫介質(zhì)的電磁閥。

（2）系統(tǒng)簡單，和電腦，價格低。電磁閥本身具有結(jié)構(gòu)簡單，價格低廉，與控制閥和其它種類的致動器相比，易于安裝和維護。由自動控制系統(tǒng)更顯著要簡單得多，價格低很多。由于電磁閥是開關(guān)信號控制，與工控計算機連接十分方便。在今天的電腦，價格暴跌，電磁閥的優(yōu)勢更加明顯。

（3）動作快遞，功率微小，外形輕巧。電磁閥響應時間可以短至幾毫秒，甚至引導式電磁閥可以在幾毫秒的控制。因為它的電路，比在反應等自動控制閥更敏感的。電磁閥線圈功耗設(shè)計低，節(jié)能型產(chǎn)品;也可以簡單地觸發(fā)動作，自動保持閥位，沒有電平時。電磁閥外形尺寸，節(jié)省空間已經(jīng)和輕盈，美觀。

（4）調(diào)節(jié)精度受限，有限的適宜的培養(yǎng)基。 ，電磁閥，通常只有兩個狀態(tài)開關(guān)閥芯是僅在這兩個極限位置，不連續(xù)的調(diào)節(jié)，（試圖打破了很多新的概念，而且在測試試驗階段），以使調(diào)整精度是有限的。電磁閥有更高的要求，以介質(zhì)的清潔度，含有介質(zhì)顆粒不適用的，必須對過濾雜質(zhì)。此外，粘性介質(zhì)不能適用，并應適用于中等粘度范圍的特定產(chǎn)品相對較窄。

（5）類型多樣，用途廣泛。電磁閥是先天不足，優(yōu)勢依然突出，所以他設(shè)計了多種產(chǎn)品，滿足不同的需求，用途非常廣泛。電磁閥技術(shù)的進步也圍繞著如何克服的不足，如何更好地發(fā)揮固有優(yōu)勢。

(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.
