1. 產品描述：

   無負壓(ya)給(gei)水(shui)(shui)(shui)(shui)(shui)設備是直接(jie)利(li)用自(zi)來水(shui)(shui)(shui)(shui)(shui)管網(wang)壓(ya)力的一種疊壓(ya)式供水(shui)(shui)(shui)(shui)(shui)方式，衛生、節能(neng)、綜合投資小。安(an)裝調試后，自(zi)來水(shui)(shui)(shui)(shui)(shui)管網(wang)的水(shui)(shui)(shui)(shui)(shui)首先進(jin)入穩(wen)流補償(chang)器(qi)，并通(tong)過真空(kong)(kong)(kong)抑制器(qi)將(jiang)罐(guan)內的空(kong)(kong)(kong)氣自(zi)動(dong)排除(chu)。當(dang)(dang)(dang)安(an)裝在設備出口的壓(ya)力傳感器(qi)檢測到自(zi)來水(shui)(shui)(shui)(shui)(shui)管網(wang)壓(ya)力滿(man)足供水(shui)(shui)(shui)(shui)(shui)要求時(shi)(shi)，系統不(bu)經(jing)過加壓(ya)泵直接(jie)供給(gei)；當(dang)(dang)(dang)自(zi)來水(shui)(shui)(shui)(shui)(shui)管網(wang)壓(ya)力不(bu)能(neng)滿(man)足供水(shui)(shui)(shui)(shui)(shui)要求時(shi)(shi)，檢測壓(ya)力差額，由加壓(ya)泵差多少、補多少；當(dang)(dang)(dang)自(zi)來水(shui)(shui)(shui)(shui)(shui)管網(wang)水(shui)(shui)(shui)(shui)(shui)量不(bu)足時(shi)(shi)，空(kong)(kong)(kong)氣由真空(kong)(kong)(kong)抑制器(qi)進(jin)入穩(wen)流補償(chang)器(qi)破壞罐(guan)內真空(kong)(kong)(kong)，即可自(zi)動(dong)抽取穩(wen)流補償(chang)器(qi)內的水(shui)(shui)(shui)(shui)(shui)供給(gei)，并且管網(wang)內不(bu)產生負壓(ya)。
