電(dian)(dian)(dian)(dian)動(dong)(dong)裝(zhuang)(zhuang)置(zhi)配有轉(zhuan)矩控制(zhi)機(ji)構(gou)、現場(chang)操(cao)作(zuo)(zuo)機(ji)構(gou)和(he)手(shou)、電(dian)(dian)(dian)(dian)動(dong)(dong)切換(huan)機(ji)構(gou)。除就地操(cao)作(zuo)(zuo)外(wai)，還可(ke)以進行遠距離操(cao)作(zuo)(zuo)、PLC控制(zhi)、4~20mA電(dian)(dian)(dian)(dian)流輸入輸出智能控制(zhi)等。手(shou)動(dong)(dong)閥(fa)門(men)(men)由手(shou)動(dong)(dong)機(ji)構(gou)或撞擊(ji)時(shi)手(shou)輪(lun)開啟。減小閥(fa)門(men)(men)操(cao)作(zuo)(zuo)力。閥(fa)門(men)(men)可(ke)安(an)(an)裝(zhuang)(zhuang)在(zai)管道的任何位(wei)置(zhi)，同時(shi)根據(ju)介質和(he)介質的溫度選擇碳鋼或合金鋼閥(fa)門(men)(men)。初次安(an)(an)裝(zhuang)(zhuang)和(he)調試時(shi)，必須(xu)手(shou)動(dong)(dong)把閥(fa)門(men)(men)開到約一半(ban)的位(wei)置(zhi)，以免(mian)電(dian)(dian)(dian)(dian)機(ji)相序(xu)接反導(dao)致閥(fa)門(men)(men)或電(dian)(dian)(dian)(dian)裝(zhuang)(zhuang)損壞。電(dian)(dian)(dian)(dian)動(dong)(dong)閘閥(fa)結(jie)構(gou)緊(jin)湊、設計合理、閥(fa)門(men)(men)剛(gang)性好，通道流暢，流阻系數小。

　　密封(feng)面采用不銹鋼和硬(ying)質合金，使用壽命長。采用柔(rou)性石墨(mo)填(tian)料板、密封(feng)可靠、操作輕便靈活。驅動方(fang)式(shi)(shi)分手動、電動、氣動、齒輪傳動、結構(gou)形式(shi)(shi)；彈性楔式(shi)(shi)單閥(fa)、剛性楔式(shi)(shi)單閥(fa)板和雙閘板型(xing)式(shi)(shi)。

　　廣泛適用于石油、化工、火力(li)發(fa)電(dian)廠等(deng)油品、水、蒸汽管路上作接(jie)通(tong)或(huo)截斷管路中介(jie)質的啟(qi)閉裝置。電(dian)動(dong)閘(zha)閥(fa)開閉較(jiao)省力(li)。閘(zha)閥(fa)介(jie)質流向不(bu)受(shou)限制(zhi),不(bu)擾(rao)流、不(bu)降(jiang)低壓(ya)力(li)。
