SMC電磁閥是用來控制流體的自動化基礎元件,屬于執行器;并不限于 液壓,氣動.電磁閥用于控制液壓流動方向,工廠的機械裝置一般 都由液壓鋼控制, 所以就會用到電磁閥. 電磁閥是用電磁控制的 工業設備,用在工業控制系統中調整介質的方向,流量,速度和其 他的參數.電磁閥有很多種,不同的電磁閥在控制系統的不同位置 發揮作用,最常用的是單向閥,安全閥,方向控制閥,速度調節閥 等.電磁閥是用電磁的效應進行控制,主要的控制方式由繼電器控 制.這樣,電磁閥可以配合不同的電路來實現預期的控制,而控制 的精度和靈活性都能夠保證. 圖中桿狀的物體就是通過電控制的閥桿,利用電磁力可以將閥桿打 開或者關閉. 下面以氣動系統為例子說明電磁閥在工業控制中的應用.所謂氣動 系統,就是以氣體為介質的控制系統.氣動系統中,這種能源的介 質通常就是空氣.在真正使用的時候,通常把大氣中的空氣的體積 加以壓縮,從而提高它的壓力.壓縮空氣主要通過作用于活塞或葉 片來作功. 

氣(qi)(qi)(qi)動系(xi)(xi)統中(zhong),電磁閥(fa)的(de)作用就是(shi)在控(kong)制(zhi)系(xi)(xi)統中(zhong)按照(zhao)控(kong)制(zhi)的(de)要(yao)求來調 整(zheng)壓(ya)(ya)縮空氣(qi)(qi)(qi)的(de)各種狀態,氣(qi)(qi)(qi)動系(xi)(xi)統還需(xu)要(yao)其他元(yuan)(yuan)件的(de)配合,其中(zhong)包 括(kuo)(kuo)(kuo)動力元(yuan)(yuan)件,執行(xing)元(yuan)(yuan)件,開(kai)關,顯示設(she)備(bei)及其它輔助設(she)備(bei).動力元(yuan)(yuan) 件包括(kuo)(kuo)(kuo)各種壓(ya)(ya)縮機,執行(xing)元(yuan)(yuan)件包括(kuo)(kuo)(kuo)各種氣(qi)(qi)(qi)缸.這些(xie)都(dou)是(shi)氣(qi)(qi)(qi)動系(xi)(xi)統中(zhong) 不可缺少的(de)部分.而(er)閥(fa)體(ti)是(shi)控(kong)制(zhi)算法得以(yi)實(shi)現的(de)重要(yao)設(she)備(bei).比如單向閥(fa)讓壓(ya)(ya)縮空氣(qi)(qi)(qi)從(cong)壓(ya)(ya)縮機進入氣(qi)(qi)(qi)罐,當壓(ya)(ya)縮機關閉(bi)時,阻止 壓(ya)(ya)縮空氣(qi)(qi)(qi)反方(fang)向流動;安全(quan)閥(fa)當儲氣(qi)(qi)(qi)罐內的(de)壓(ya)(ya)力超過(guo)允許限度(du),可 將壓(ya)(ya)縮空氣(qi)(qi)(qi)排(pai)(pai)出(chu);方(fang)向控(kong)制(zhi)閥(fa)通過(guo)對氣(qi)(qi)(qi)缸兩(liang)個接(jie)口(kou)交替地加壓(ya)(ya)和排(pai)(pai) 氣(qi)(qi)(qi),來控(kong)制(zhi)運動的(de)方(fang)向;速(su)(su)度(du)調節(jie)閥(fa)能(neng)簡(jian)便實(shi)現執行(xing)元(yuan)(yuan)件的(de)無級調 速(su)(su).
