電動(dong)(dong)插(cha)(cha)板(ban)(ban)閥(fa)裝車送貨：電動(dong)(dong)插(cha)(cha)板(ban)(ban)閥(fa)啟閉件(jian)是閘板(ban)(ban)，閘板(ban)(ban)的(de)運動(dong)(dong)方(fang)(fang)向(xiang)與流體方(fang)(fang)向(xiang)相垂直，電動(dong)(dong)插(cha)(cha)板(ban)(ban)閥(fa)只(zhi)能(neng)(neng)作(zuo)全(quan)(quan)開(kai)和(he)全(quan)(quan)關，不能(neng)(neng)作(zuo)調(diao)節(jie)和(he)節(jie)流。閘板(ban)(ban)有兩(liang)個密封面， 常(chang)用(yong)的(de)模式閘板(ban)(ban)閥(fa)的(de)兩(liang)個密封面形(xing)(xing)成楔形(xing)(xing)、楔形(xing)(xing)角(jiao)隨閥(fa)門參數而(er)異。電動(dong)(dong)插(cha)(cha)板(ban)(ban)閥(fa)原理：閘板(ban)(ban)上開(kai)有一個通(tong)(tong)徑大小(xiao)的(de)圓(yuan)口，通(tong)(tong)過閘板(ban)(ban)啟閉使(shi)得閘板(ban)(ban)上圓(yuan)口跟(gen)通(tong)(tong)徑做(zuo)完全(quan)(quan)脫離(li)和(he)相吻合的(de)動(dong)(dong)作(zuo)。
