彈簧6的彈簧力,被靜鐵心2所被吸引,IN口與OUT開啟。N.C.型的圖
漏易控,使用安全。內(nèi)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(dòng)、氣動(dòng)、液動(dòng)執(zhí)行機(jī)構(gòu)控制閥芯的轉(zhuǎn)動(dòng)或移動(dòng)。這都要解決長(zhǎng)期動(dòng)作閥桿
動(dòng)密封的外泄漏難題;唯有電磁閥是用電磁力作用于密封在電動(dòng)調(diào)節(jié)閥隔磁套管
內(nèi)的鐵芯完成,不存在動(dòng)密封,所以外漏易堵絕。
2電動(dòng)閥力矩控制不易,容易產(chǎn)生內(nèi)漏,甚至拉斷閥桿頭部;電磁閥的結(jié)構(gòu)型式容

易控制內(nèi)泄漏,直至降為零。所以,電磁閥使用特別安全,尤其適用于腐蝕性有毒
或高溫的介質(zhì)。3、SMC電磁閥系統(tǒng)簡(jiǎn)單,便接電腦,謙。電磁閥本身結(jié)構(gòu)簡(jiǎn)單
,也,比起調(diào)節(jié)閥等其它種類執(zhí)行器易于安裝維護(hù)。更顯著的是所組成的自控系統(tǒng)簡(jiǎn)單得多
形符號(hào)表示,在不通電時(shí),IN口至OUT口是封閉的,但若OUT口與IN口對(duì)換,則不能封閉。.
