電(dian)(dian)動(dong)閘閥(fa)(fa)(fa)介質多為堿性泥漿(jiang)和顆粒狀(zhuang)物質，氧化(hua)鋁(lv)工業在生產過程中。結疤現(xian)象(xiang)*為嚴(yan)重，且(qie)介質對電(dian)(dian)動(dong)閥(fa)(fa)(fa)電(dian)(dian)動(dong)閘閥(fa)(fa)(fa)門體(ti)腔(qiang)及(ji)內件的沖(chong)蝕(shi)現(xian)象(xiang)也很(hen)嚴(yan)重。因此，氧化(hua)鋁(lv)工業用閥(fa)(fa)(fa)要求(qiu)其抗結疤耐(nai)結疤;抗沖(chong)蝕(shi)耐(nai)沖(chong)蝕(shi)電(dian)(dian)動(dong)閥(fa)(fa)(fa)門開關(guan)動(dong)作速度可以調(diao)整，電(dian)(dian)動(dong)閥(fa)(fa)(fa)門動(dong)作力距比電(dian)(dian)動(dong)閥(fa)(fa)(fa)門大(da)。結構簡單，易維護(hu)，動(dong)作過程中因氣體(ti)本(ben)身的緩沖(chong)特性，不易因卡住而損壞，但必須(xu)有氣動(dong)球閥(fa)(fa)(fa)氣源(yuan)，且(qie)其控制系(xi)統(tong)也比電(dian)(dian)動(dong)閥(fa)(fa)(fa)門復雜。

　　電動(dong)閥(fa)門(men)開關動(dong)作(zuo)速度可以(yi)調整，電動(dong)閥(fa)門(men)動(dong)作(zuo)力距(ju)比電動(dong)閥(fa)門(men)大。結構簡單，易維護，動(dong)作(zuo)過(guo)程中因氣體本身的緩沖特性，不易因卡(ka)住(zhu)而損(sun)壞，但必須有氣動(dong)球閥(fa)氣源(yuan)，且(qie)其控制系統也比電動(dong)閥(fa)門(men)復雜(za)。

什么是電動閥：

　　電(dian)(dian)動閥(fa)(fa)簡(jian)單地說就是用(yong)電(dian)(dian)動執行器(qi)(qi)控制(zhi)閥(fa)(fa)門(men)(men),一。從而實現(xian)閥(fa)(fa)門(men)(men)的開和關(guan)。其可分(fen)為上(shang)下兩部(bu)分(fen)，上(shang)半(ban)部(bu)分(fen)為電(dian)(dian)動執行器(qi)(qi)，下半(ban)部(bu)分(fen)為閥(fa)(fa)門(men)(men)。

　　一(yi)(yi)種為角(jiao)(jiao)行(xing)(xing)(xing)程(cheng)電動(dong)(dong)閥：由(you)角(jiao)(jiao)行(xing)(xing)(xing)程(cheng)的電動(dong)(dong)執行(xing)(xing)(xing)器配合(he)角(jiao)(jiao)行(xing)(xing)(xing)程(cheng)的閥使用(yong)，電動(dong)(dong)閥分兩種。實現閥門(men)90度以內旋控(kong)(kong)制管(guan)(guan)道流(liu)體(ti)通(tong)斷;另一(yi)(yi)種為直行(xing)(xing)(xing)程(cheng)電動(dong)(dong)閥：由(you)直行(xing)(xing)(xing)程(cheng)的電動(dong)(dong)執行(xing)(xing)(xing)器配合(he)直行(xing)(xing)(xing)程(cheng)的閥使用(yong)，實現閥板(ban)上下(xia)動(dong)(dong)作控(kong)(kong)制管(guan)(guan)道流(liu)體(ti)通(tong)斷。通(tong)常在自動(dong)(dong)化程(cheng)度較高的設備上配套(tao)使用(yong)。
