    另外，有些(xie)閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)如翻板(ban)閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)可借(jie)助水(shui)力(li)(li)自(zi)動啟(qi)閉，稱為水(shui)力(li)(li)自(zi)動閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)。衡陽市鳳凰卷閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)建議選擇(ze)閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)形式(shi)需要(yao)考(kao)慮其在水(shui)工(gong)建筑(zhu)物中(zhong)的位置、尺(chi)寸、設計水(shui)頭(tou)(tou)、運用(yong)(yong)條件(jian)、制造能力(li)(li)和(he)(he)(he)安裝技術水(shui)平等因(yin)素，要(yao)求做到(dao)泄流(liu)時水(shui)流(liu)條件(jian)好(hao)、止水(shui)嚴密、啟(qi)閉力(li)(li)小、操作(zuo)簡便(bian)(bian)靈活(huo)、檢修(xiu)維護方便(bian)(bian)等。平面閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)和(he)(he)(he)弧(hu)形閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)是最常用(yong)(yong)的門(men)(men)(men)(men)(men)型。在工(gong)作(zuo)閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)中(zhong)，大型露頂式(shi)閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)和(he)(he)(he)高水(shui)頭(tou)(tou)潛孔式(shi)閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)多(duo)(duo)用(yong)(yong)弧(hu)形閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)，船閘(zha)(zha)(zha)上多(duo)(duo)用(yong)(yong)人字閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)和(he)(he)(he)橫(heng)拉閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)，檢修(xiu)閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)和(he)(he)(he)事故閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)一(yi)般都用(yong)(yong)平面閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)。制造門(men)(men)(men)(men)(men)葉的材料近(jin)代多(duo)(duo)用(yong)(yong)鋼材，而鋼筋混凝土多(duo)(duo)用(yong)(yong)做需要(yao)借(jie)自(zi)重關閉施工(gong)導流(liu)底孔的封堵閘(zha)(zha)(zha)門(men)(men)(men)(men)(men)。此外，在壓力(li)(li)管道中(zhong)使用(yong)(yong)的將門(men)(men)(men)(men)(men)葉、外殼和(he)(he)(he)啟(qi)閉機(ji)械組成一(yi)體的控制設施，通稱閥門(men)(men)(men)(men)(men)。
    閘(zha)(zha)(zha)門(men)是裝(zhuang)于溢(yi)流壩、岸邊溢(yi)洪道(dao)、泄水(shui)孔、水(shui)工(gong)隧洞(dong)和水(shui)閘(zha)(zha)(zha)等建筑(zhu)物的(de)空口上，用以調(diao)節流量，控制(zhi)上、下游水(shui)位(wei)、宣泄洪水(shui)、排(pai)除泥沙或(huo)漂浮物等，是水(shui)工(gong)建筑(zhu)物的(de)重要組(zu)成部分(fen)(fen)。在水(shui)閘(zha)(zha)(zha)工(gong)程中，閘(zha)(zha)(zha)門(men)是主體部分(fen)(fen)，常占擋水(shui)面積的(de)大部。閘(zha)(zha)(zha)門(men)又分(fen)(fen)為平(ping)板閘(zha)(zha)(zha)門(men)和弧形閘(zha)(zha)(zha)門(men).
    結構組成:
    閘門主要(yao)由三部分(fen)組成:
    ①主體活動部(bu)分(fen)，用以封閉或開(kai)放孔(kong)口，通稱(cheng)閘門，亦稱(cheng)門葉；
    ②埋固部分；
    ③起閉設備(bei)。
    閘(zha)門(men)(men)是(shi)堅固的(de)柵欄(lan)(lan)，位在城(cheng)(cheng)門(men)(men)的(de)信道(dao)上，必要(yao)時可以(yi)落下以(yi)堵住門(men)(men)口(kou)。城(cheng)(cheng)堡(bao)的(de)城(cheng)(cheng)門(men)(men)是(shi)一(yi)個(ge)有內部空(kong)間的(de)門(men)(men)房，乃(nai)防衛城(cheng)(cheng)堡(bao)的(de)堅固據點。人(ren)們可以(yi)透(tou)過一(yi)條隧(sui)道(dao)從城(cheng)(cheng)門(men)(men)的(de)信道(dao)到達門(men)(men)房。在隧(sui)道(dao)的(de)中間或(huo)兩端，會有一(yi)層或(huo)多層的(de)閘(zha)門(men)(men)。滾動的(de)機械作用可在門(men)(men)房的(de)上方吊起(qi)或(huo)落下閘(zha)門(men)(men)做扎實的(de)防護。閘(zha)門(men)(men)本身通常為沉重的(de)木制或(huo)鐵(tie)制欄(lan)(lan)柵，防衛者和(he)攻城(cheng)(cheng)者則(ze)在閘(zha)門(men)(men)的(de)兩邊射擊或(huo)刺戳。
