進(jìn)口閘閥(gate valve)的啟閉件是閘板,閘板的運動方向與流體方向相垂直,閘閥只能作全開和全關(guān) , 上海方工 , 閘閥兩個密封面形成楔形、楔形角隨閥門參數(shù)而異 , 通常為 50, 介質(zhì)溫度不高時為 425℃ 。改善其工藝性 , 彌補密封面角度在加工過程中產(chǎn)生的偏差 , 這種閘板叫做彈性閘板。

Gate valve is a gate opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, Shanghai worker, gate valve sealing surface to form two wedge, wedge angle varies with the valve parameters, usually 50, medium is not high temperature is 425 ℃. To improve the process of the deviation, make up the sealing surface angle in the process, this gate is called the flexible gate進(jìn)口閘閥產(chǎn)品分為碳鋼閘閥、鍛鋼閘閥、不銹鋼閘閥、鑄鋼閘閥、鑄鐵閘閥、陶瓷閘閥,楔式閘板式閘閥和平行閘板式閘閥,楔式閘板式閘閥,單閘板式、雙閘板式和彈性閘板式,,明桿閘閥,暗桿閘閥,彈性座封閘閥,軟密封閘閥,電動閘閥,氣動閘閥。
