鑄鐵鑲銅方閘門供應水利設備結構組成

閘門主要由三部分組成:

①主(zhu)體(ti)活動部分，用以封閉或開放孔口，通稱閘門，亦稱門葉;

②埋固部分;

③啟閉設備。

活(huo)動(dong)(dong)部(bu)(bu)分包括面板梁系(xi)等(deng)稱重結構(gou)、支承(cheng)行走(zou)部(bu)(bu)件、導(dao)向(xiang)及止(zhi)水(shui)(shui)(shui)裝置和(he)吊耳(er)等(deng)。埋(mai)(mai)件部(bu)(bu)分包括主軌、導(dao)軌、鉸座、門楣、底檻、止(zhi)水(shui)(shui)(shui)座等(deng)，它們(men)埋(mai)(mai)設在孔口周邊，用(yong)錨筋與水(shui)(shui)(shui)工建筑物的混凝土牢固(gu)連接，分別形成與門葉上支承(cheng)行走(zou)部(bu)(bu)件及止(zhi)水(shui)(shui)(shui)面，以(yi)便(bian)將門葉結構(gou)所承(cheng)受的水(shui)(shui)(shui)壓力等(deng)荷載傳遞給水(shui)(shui)(shui)工建筑物，并獲得良(liang)好的閘門止(zhi)水(shui)(shui)(shui)性能。啟閉機械與門葉吊耳(er)連接，以(yi)操作(zuo)控制活(huo)動(dong)(dong)部(bu)(bu)分的位置，但也有少(shao)數閘門借(jie)助水(shui)(shui)(shui)力自動(dong)(dong)控制操作(zuo)啟閉。
