閘(zha)(zha)門(men)(men)(men)分(fen)(fen)類：按閘(zha)(zha)門(men)(men)(men)門(men)(men)(men)頂(ding)與水(shui)(shui)(shui)平(ping)面相對位(wei)置劃分(fen)(fen)。主要有露(lu)頂(ding)式閘(zha)(zha)門(men)(men)(men)和潛沒(mei)式閘(zha)(zha)門(men)(men)(men)。當堰(yan)門(men)(men)(men)一(yi)部(bu)(bu)分(fen)(fen)泡在水(shui)(shui)(shui)里，管路內部(bu)(bu)工(gong)(gong)作壓力很大(da)(da)，反(fan)方向工(gong)(gong)作壓力較鐘頭，堰(yan)門(men)(men)(men)容許一(yi)部(bu)(bu)分(fen)(fen)走漏量(liang)，當河堤壓力擴大(da)(da)時(shi)(shi)，蚌埠下開(kai)(kai)式堰(yan)門(men)(men)(men)，拍守門(men)(men)(men)員全(quan)自動關掉(diao)密封(feng)性。開(kai)(kai)敞式水(shui)(shui)(shui)閘(zha)(zha)當閘(zha)(zha)門(men)(men)(men)全(quan)開(kai)(kai)時(shi)(shi)過(guo)(guo)閘(zha)(zha)水(shui)(shui)(shui)流通暢，適用于有泄洪、排(pai)冰、過(guo)(guo)木或排(pai)漂浮(fu)物等任務(wu)要求的水(shui)(shui)(shui)閘(zha)(zha)，智(zhi)能下開(kai)(kai)式堰(yan)門(men)(men)(men)，節制閘(zha)(zha)、分(fen)(fen)洪閘(zha)(zha)常用這種形式。

閘(zha)(zha)(zha)門(men)(men)(men)分類：按(an)制作材料劃分。主(zhu)要(yao)有木質閘(zha)(zha)(zha)門(men)(men)(men)、木面板(ban)鋼(gang)構(gou)架閘(zha)(zha)(zha)門(men)(men)(men)、鑄鐵閘(zha)(zha)(zha)門(men)(men)(men)、鋼(gang)筋混凝土閘(zha)(zha)(zha)門(men)(men)(men)以(yi)(yi)及鋼(gang)閘(zha)(zha)(zha)門(men)(men)(men)。堰門(men)(men)(men)適(shi)用(yong)給(gei)水(shui)(shui)(shui)排水(shui)(shui)(shui)及廢(fei)水(shui)(shui)(shui)處理工(gong)程的(de)林(lin)(lin)林(lin)(lin)總總管路和(he)(he)水(shui)(shui)(shui)方法作溢流式、止(zhi)回之用(yong)，以(yi)(yi)成作為林(lin)(lin)林(lin)(lin)總總立(li)井下水(shui)(shui)(shui)井蓋，它僅用(yong)以(yi)(yi)單邊(bian)水(shui)(shui)(shui)流量的(de)排水(shui)(shui)(shui)口。修建在(zai)河道(dao)和(he)(he)渠道(dao)上利用(yong)閘(zha)(zha)(zha)門(men)(men)(men)控(kong)制流量和(he)(he)調(diao)節水(shui)(shui)(shui)位(wei)的(de)低水(shui)(shui)(shui)頭(tou)水(shui)(shui)(shui)工(gong)建筑物。關閉閘(zha)(zha)(zha)門(men)(men)(men)可(ke)以(yi)(yi)攔(lan)洪、擋潮或(huo)抬高上游(you)水(shui)(shui)(shui)位(wei)，以(yi)(yi)滿足灌溉、發電、航運(yun)、水(shui)(shui)(shui)產、環保(bao)、工(gong)業和(he)(he)生活用(yong)水(shui)(shui)(shui)等需要(yao)。

不銹鋼旋轉(zhuan)式調(diao)(diao)節堰(yan)(yan)門(men)是在消(xiao)化吸收(shou)國(guo)外技術的(de)基礎上，結(jie)合(he)我國(guo)國(guo)情研(yan)制(zhi)而成的(de)可自動(dong)控制(zhi)調(diao)(diao)節水(shui)(shui)位(wei)(液位(wei))的(de)堰(yan)(yan)門(men)。堰(yan)(yan)門(men)蓋(gai)上下(xia)設拉環，下(xia)開(kai)式閘門(men)和下(xia)開(kai)式堰(yan)(yan)門(men)，帶動(dong)拉環此蓋(gai)的(de)翻開(kai)視角應跨越65度(du)，截流(liu)井(jing)液動(dong)下(xia)開(kai)式堰(yan)(yan)門(men)，無卡阻(zu)問題(ti)，電源(yuan)開(kai)關應隨意靈活(huo)。堰(yan)(yan)門(men)適用給水(shui)(shui)排水(shui)(shui)及廢(fei)水(shui)(shui)處理工程的(de)林林總(zong)(zong)(zong)總(zong)(zong)(zong)管(guan)路和水(shui)(shui)方法作(zuo)溢流(liu)式、止回之用，以(yi)成作(zuo)為林林總(zong)(zong)(zong)總(zong)(zong)(zong)立井(jing)下(xia)水(shui)(shui)井(jing)蓋(gai)，它僅用以(yi)單邊(bian)水(shui)(shui)流(liu)量的(de)排水(shui)(shui)口(kou)。
