分析電動調節閥在系統中會出現的故障

　　在(zai)閥(fa)(fa)(fa)(fa)門關閉的狀態下,松開(kai)夾緊裝(zhuang)(zhuang)置(zhi)(zhi)的拉桿(gan),在(zai)電(dian)動(dong)(dong)(dong)裝(zhuang)(zhuang)置(zhi)(zhi)的帶動(dong)(dong)(dong)下拉動(dong)(dong)(dong)活動(dong)(dong)(dong)閥(fa)(fa)(fa)(fa)座離開(kai)閥(fa)(fa)(fa)(fa)板(ban)(ban)密封(feng)圈,并形成間隙,閥(fa)(fa)(fa)(fa)板(ban)(ban)橫移機構通過鏈輪拖動(dong)(dong)(dong)閥(fa)(fa)(fa)(fa)板(ban)(ban)動(dong)(dong)(dong)作,形成閥(fa)(fa)(fa)(fa)板(ban)(ban)“通孔”與“盲板(ban)(ban)”的轉換,閥(fa)(fa)(fa)(fa)板(ban)(ban)轉換位后,活動(dong)(dong)(dong)閥(fa)(fa)(fa)(fa)座同時回位,頂開(kai)機構重新壓緊閥(fa)(fa)(fa)(fa)板(ban)(ban)密封(feng)圈,形成密封(feng)。...

控制閥-方向控制閥的實際分類方法

在(zai)實習(xi)運(yun)用(yong)中，方向(xiang)控(kong)(kong)制閥(fa)(fa)可(ke)依據(ju)不一樣的需要將(jiang)方向(xiang)控(kong)(kong)制閥(fa)(fa)分紅(hong)若干(gan)品(pin)種：?　　（1）方向(xiang)控(kong)(kong)制閥(fa)(fa)按照氣體在(zai)管(guan)道(dao)的活動方向(xiang)，假設只(zhi)允許氣體向(xiang)一個(ge)方向(xiang)活動，這么的閥(fa)(fa)叫做單向(xiang)型控(kong)(kong)制閥(fa)(fa)，比(bi)方單向(xiang)閥(fa)(fa)，梭(suo)閥(fa)(fa)等；可(ke)以(yi)改動氣體流向(xiang)的控(kong)(kong)制閥(fa)(fa)叫做換向(xiang)閥(fa)(fa)。?　　（2）...
