電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)重錘(chui)翻(fan)板(ban)閥(fa)(fa)簡(jian)單(dan)地說就(jiu)是(shi)用電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)執行(xing)器(qi)控制閥(fa)(fa)門，從而實現(xian)閥(fa)(fa)門的(de)開(kai)和關。其(qi)可分(fen)為(wei)上(shang)下兩部分(fen)，上(shang)半部分(fen)為(wei)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)執行(xing)器(qi)，下半部分(fen)為(wei)閥(fa)(fa)門。動(dong)(dong)(dong)(dong)作(zuo)力距比(bi)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)閥(fa)(fa)門大，電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)閘閥(fa)(fa)開(kai)關動(dong)(dong)(dong)(dong)作(zuo)速度可以調(diao)整，結構簡(jian)單(dan)，易維護(hu)，動(dong)(dong)(dong)(dong)作(zuo)過程中因(yin)氣(qi)體本身(shen)的(de)緩(huan)沖特性，不易因(yin)卡住而損壞，但必(bi)須(xu)有(you)氣(qi)源(yuan)，且其(qi)控制系統(tong)也(ye)比(bi)電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)閥(fa)(fa)門復雜。 電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)閘閥(fa)(fa)響應靈(ling)敏，安全可靠。電(dian)(dian)(dian)動(dong)(dong)(dong)(dong)的(de)就(jiu)是(shi)要有(you)電(dian)(dian)(dian)，并能控制其(qi)流量的(de)裝置(zhi)。

腭式放料閥特點：

1、結(jie)構緊湊、設計合理、閥門剛(gang)性好，通道流(liu)(liu)暢，流(liu)(liu)阻(zu)系(xi)數小。

2、密封面采用不銹(xiu)鋼和硬質合金，使用壽命長。

3、采用柔性石(shi)墨(mo)填料板、密封(feng)可靠、操作(zuo)輕便靈(ling)活。

4、驅(qu)動(dong)方式(shi)(shi)分手(shou)動(dong)、電動(dong)、氣(qi)動(dong)、齒輪傳動(dong)、結構形式(shi)(shi)；彈性楔式(shi)(shi)單(dan)閥、剛性楔式(shi)(shi)單(dan)閥板和雙閘板型(xing)式(shi)(shi)。

5、廣泛適用于石油、化(hua)工、火(huo)力(li)發(fa)電(dian)廠(chang)等油品、水(shui)、蒸(zheng)汽(qi)管路上作接通或截(jie)斷管路中介質的啟閉裝(zhuang)置。

6、閘閥開閉較省力(li)。

7、閘閥介質(zhi)流(liu)向不受限制,不擾(rao)流(liu)、不降低壓力。
