液动下开式堰门用于管道、箱涵或渠道中。可以起到冲洗、防倒灌、调节的作用。该设备向下开启，不占用上部空间，故称下开式堰门。<br/>晴天的时候为正常模式，即液动限流闸门全开，液动下开式堰门全关状态，此时井内全部为污水，经由污水口排入污水管网；雨天的时候将转变状态，当井内液位，现场雨量有了涨幅，SCADD系统将根据数据运转设备，例如液位雨量达到一定数值，限流闸门关闭四分，下开式堰门开启三分；持续上涨，限流闸门则关闭四分之三，下开式堰门开启一半；如果液位达到警戒值，雨量持续上涨，此时雨水过多混入污水管网城市进入内涝状态，则限流闸门全部关闭，液动下开式堰门彻底开启，井内的雨水全部排入雨水管网，泾排口流入附近的河道和湖泊；待雨量减小、液位下降，SCADA系统根据采集的数值逐步恢复正常模式。<br/><img style="margin: auto;clear: both;display: block" src="//l.b2b168.com/2020/08/06/10/202008061035146299214.jpg" alt="丽江截流井液动下开式堰门"/><br/>液动下开式堰门初期只是一种渠道、河道闸门，只有简单的蓄水、排水功能。经过我公司的多年研究，加入一定的技术，用于城市沿河排口，尤其是大型排口，对河道的水质的改善与治理拥有奇效。简单的来讲液动下开式堰门配合液动限流闸门使用，能实现雨污分流的作用，就是说晴天使污水进入污水管网，发挥排污功能；雨天能将雨水拍入河道，实行排涝功能。<br/><img style="margin: auto;clear: both;display: block" src="//l.b2b168.com/2020/08/06/10/202008061028390948394.jpg" alt="丽江截流井液动下开式堰门"/><br/>液动下开式堰门图纸驱动端与所述门板端面铰接；流道基体上设有安装座，安装座上设有转轴；门板底部与所述转轴转动连接；门板两侧与流道基体侧壁之间接触式密封。门板上游流道基体底面**安装所述安装座的流道基体底面。这样，能够使得门板能够处于水平位置，从而使流道完全打开。流道基体底面包括高位段和低位段，高位段和低位段为台阶结构；安装座设在低位段，且靠近高位段和低位段的过渡处。门板的旋转中心不**所述高位段表面。门板表面与门板上游流道基体底面之间设有橡胶密封件。确保门板底部与流道基体之间的密封性。橡胶密封件与所述流道基体底部同宽；橡胶密封件沿流向的一端与流道基体底部可拆卸连接，另一端与门板表面连接。门板表面与高位段表面之间设有橡胶密封件。<br/><img style="margin: auto;clear: both;display: block" src="//l.b2b168.com/2020/08/06/10/202008061035081934134.jpg" alt="丽江截流井液动下开式堰门"/><br/>超声波液位传感器检测堰门两侧水位转换为电信号给控制系统，控制系统驱动堰门上的油缸驱动堰板前后移动，两侧及底部装有橡胶密封件起到密封作用（可做三面或四面密封），同时油缸带有位移传感器，能控制堰板在任意位置停止，在停电实时，控制上游水位、冲洗、防倒灌等多种功能。<br /><a href="http://18761521967.cn.b2b168.com/">http://18761521967.cn.b2b168.com</a>
