水箱,水池蓄水专用进出水自动开关活塞式液压水位控制阀
活塞式液压水位控制阀,是一种自动控制水箱、水塔液面高度的水力控制阀。当水面下降超过预设值时，浮球阀打开，活塞上腔室压力降低，活塞上下形成压差，在此压差作用下阀瓣打开进行供水作业；当水位上升到预设高度时，浮球阀关闭，活塞上腔室压力不断增大致使阀瓣关闭停止供水。如此往复自动控制液面在设定高度，实现自动供水功能。该产品适用于工矿企业、民用建筑中各种水箱（池）、水塔的自动供水系统。并可用作常压锅炉循环供水控制阀。
活塞式液压水位控制阀工作原理
当水池或水塔内水位下降，浮球阀开启排水时，进水管内有压水将阀内活塞托起，密封面打开，阀门即开启供水，当水位上升到控制阀时，浮球阀关闭，活塞下移将密封面封闭，阀门即停止供水。
