影響ASCO電磁閥技術發展的因素資料有哪些？
ASCO電磁閥中的密封部件防止介質泄露的強弱能力稱為電磁閥的密封。在選購電磁閥的時候，密封性作為項技術參數也是重要的選型依據之。般意義上我們說電磁閥的密封部件主要就是指的是閥桿和填料函配合處，閥蓋和閥體連接的地方、啟閉件和閥座兩密封面連接處。平時我們經常會說到內漏和外漏現象，外漏通常就是前兩種密封部位泄露，內漏就是zui后種情況的泄露，說白了內漏就是關不嚴，外漏就是介質由閥內泄露到閥外了。兩種泄露情況都很影響電磁閥的工作，甚有時候會發生事故。內漏主要是影響閥門截斷介質的能力，所以在截斷閥中，內漏與否是判斷閥好壞的個重要標準。外漏則會導致介質的浪費以及污染環境。尤其是當介質是有毒性、有放射性或者易燃易爆的時候，外漏就是明令禁止的，所以此類電磁閥的選擇更是關重要，必須要求有的密封。
ASCO電磁閥作為自動化儀表的種執行器，近年來用量急劇上升。本文分析了ASCO電磁閥的主要特點，并側重應用的角度對國內成熟技術的發展動態 作簡要綜述，分別在精簡化、智能化、通用化、化方向作了考察，并略對影響ASCO電磁閥技術發展的社會因素作點探討。 (1)外漏堵，內漏易控，使用安全。 內外泄漏是危及安全的要素。其它自控閥通常將閥桿伸出，由電動、氣動、液動執行機構控制閥芯的轉動或移動。這都要解決長期動作 閥桿動密封的外泄漏難題；唯有電磁閥是用電磁力作用于密封在隔磁套管內的鐵芯完成，不存在動密封，所以外漏易堵。電動閥力矩控制 不易，容易產生內漏，甚拉斷閥桿頭部；ASCO電磁閥的結構型式容易控制內泄漏，直降為零。所以，ASCO電磁閥使用特別安全，尤其適用于腐蝕 性、有毒或高低溫的介質。 (2)系統簡單，便接電腦，價格低謙。 電磁閥本身結構簡單，價格也低，比起調節閥等其它種類執行器易于安裝維護。更的是所組成的自控系統簡單得多，價格要低得多 。由于電磁閥是開關信號控制，與工控計算機連接十分方便。在當今電腦普及，價格大幅下降的時代，ASCO電磁閥的就更加。 (3)動作快遞，功率微小，外形輕巧。 ASCO電磁閥響應時間可以短幾個毫秒，即使是導式ASCO電磁閥也可以控制在幾十毫秒內。由于自成回路，比之其它自控閥反應更靈敏。設計 得當的電磁閥線圈功率消耗很低，屬節能產品；還可做到只需觸發動作，自動保持閥位，平時點也不耗電。ASCO電磁閥外形尺寸小，既節省空 間，又輕巧美觀。

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.
