閘(zha)門(men)(men)分(fen)類：按門(men)(men)葉不同的支(zhi)(zhi)承(cheng)形(xing)式劃分(fen)。主要(yao)由(you)定(ding)(ding)輪支(zhi)(zhi)承(cheng)閘(zha)門(men)(men)、鉸支(zhi)(zhi)承(cheng)閘(zha)門(men)(men)、滑道支(zhi)(zhi)承(cheng)的閘(zha)門(men)(men)、鏈輪閘(zha)門(men)(men)、串輥閘(zha)門(men)(men)、圓輥閘(zha)門(men)(men)等。堰(yan)(yan)(yan)(yan)門(men)(men)具有操作(zuo)方(fang)便、動(dong)作(zuo)靈活、，密(mi)封性(xing)好(hao)及維護(hu)方(fang)便等特點，液動(dong)下(xia)開式堰(yan)(yan)(yan)(yan)門(men)(men)優勢(shi)，可(ke)實現人工操作(zuo)或自動(dong)操作(zuo)兩種(zhong)調(diao)節方(fang)式。在(zai)嚴(yan)寒地區，智能液動(dong)下(xia)開式堰(yan)(yan)(yan)(yan)門(men)(men)，可(ke)根據用(yong)戶要(yao)求安裝(zhuang)電加熱元件以(yi)防結冰(bing)，液動(dong)下(xia)開式堰(yan)(yan)(yan)(yan)門(men)(men)排名(ming)，保證設備正常運行(xing)。堰(yan)(yan)(yan)(yan)門(men)(men)，定(ding)(ding)義為設置(zhi)在(zai)堰(yan)(yan)(yan)(yan)口用(yong)于調(diao)節堰(yan)(yan)(yan)(yan)的高度的閘(zha)門(men)(men)，種(zhong)類有鑄鐵堰(yan)(yan)(yan)(yan)門(men)(men)、鋼制直(zhi)動(dong)式堰(yan)(yan)(yan)(yan)門(men)(men)、鋼制旋轉堰(yan)(yan)(yan)(yan)門(men)(men)。

不銹鋼旋轉式調(diao)節堰(yan)(yan)門(men)是在(zai)消化吸收國(guo)外(wai)技(ji)術(shu)的基礎上(shang)，結合我國(guo)國(guo)情研制而成的可自(zi)動(dong)控制調(diao)節水(shui)(shui)(shui)位(液位)的堰(yan)(yan)門(men)。堰(yan)(yan)門(men)蓋上(shang)下設拉環，帶動(dong)拉環此蓋的翻開視角應跨越65度，無卡(ka)阻問題，電源(yuan)開關應隨意靈活。堰(yan)(yan)門(men)適用(yong)(yong)給水(shui)(shui)(shui)排水(shui)(shui)(shui)及廢水(shui)(shui)(shui)處理工程的林(lin)林(lin)總(zong)(zong)總(zong)(zong)管路和水(shui)(shui)(shui)方法作溢流式、止(zhi)回(hui)之用(yong)(yong)，以成作為(wei)林(lin)林(lin)總(zong)(zong)總(zong)(zong)立井下水(shui)(shui)(shui)井蓋，它僅用(yong)(yong)以單(dan)邊水(shui)(shui)(shui)流量的排水(shui)(shui)(shui)口。

堰(yan)(yan)門屬逆止閥產(chan)品，液動下(xia)開式堰(yan)(yan)門，要(yao)害(hai)安裝在污水(shui)(shui)(shui)管道的(de)尾部，用以(yi)防止外水(shui)(shui)(shui)倒(dao)灌。材料分紅不銹(xiu)鋼板、合金(jin)鋼、生(sheng)鐵首要(yao)原材料。對高水(shui)(shui)(shui)頭泄水(shui)(shui)(shui)工作(zuo)閘門由于經常作(zuo)動水(shui)(shui)(shui)操(cao)作(zuo)或局部開啟，應設法(fa)減少閘門振動和(he)(he)空蝕現(xian)象，改(gai)善(shan)閘門水(shui)(shui)(shui)力(li)條件，按不同(tong)的(de)部件考(kao)慮動力(li)的(de)影響，并對門體(ti)的(de)剛度(du)和(he)(he)動力(li)特征(zheng)進行分析研究。堰(yan)(yan)門蓋上下(xia)設拉(la)(la)環(huan)，帶動拉(la)(la)環(huan)此(ci)蓋的(de)翻(fan)開視(shi)角應跨越65度(du)，無卡阻問題，電源(yuan)開關應隨(sui)意靈(ling)活。
