　　下開式堰門是一種特殊的堰門結(jié)構(gòu)，主要用于控制和調(diào)節(jié)水位，也可用于配水、排水等。以下是對下開式堰門的詳細介紹：<br /> 　　1.工作原理<br /> 　　下開式堰門的工作原理主要是通過液壓驅(qū)動，控制門板的升降，以達到調(diào)節(jié)水位和控制流量的目的。當(dāng)需要調(diào)節(jié)水位時，下開式堰門可以通過控制系統(tǒng)驅(qū)動堰門兩側(cè)的油缸驅(qū)動堰板在導(dǎo)向槽中上下滑動，導(dǎo)向槽的兩側(cè)及底部裝有橡膠密封件起到密封作用，同時油缸帶有位移傳感器，能控制堰板在任意位置停止，以控制上游水位、沖洗、防倒灌等多種功能。<br /> 　　2.特點<br /> 　　下開式堰門的特點主要體現(xiàn)在以下幾個方面：首先，它的結(jié)構(gòu)緊湊，堰門向下開啟，下開式堰門不占用上部的安裝空間，不影響地面上的景觀；其次，堰門可停在任意的高度位置；再次，堰門可以就地或遠程監(jiān)控；然后，它可以雙向密封，主要采用不銹鋼制成，具有很好的耐腐蝕性，維護、保養(yǎng)簡單方便，使用壽命長。<br /> <p> 　　下開式堰門主要用于管道、箱涵或渠道中，可以起到截流、防倒灌、調(diào)節(jié)流量的作用。該設(shè)備向下開啟，不占用上部空間，采用液壓式啟閉機啟閉，因稱液動下開式堰門。在城市給排水工程中，給水裝置和排水裝置往往分工明確，隨著城市中給排水系統(tǒng)的建設(shè)越來越完善，對于既能用于給水工程（配水）又能用于排水工程（調(diào)節(jié)上游水位）的裝置的需求越來越大。
