水流指示器閥門

水(shui)流(liu)指(zhi)示器(qi)(qi)主(zhu)要(yao)安(an)裝在分層或(huo)分區(qu)域的(de)自動噴淋系統(tong)的(de)水(shui)平干道上，在自動噴淋系統(tong)中(zhong)起(qi)著檢測和指(zhi)示報警區(qu)域的(de)作用。一旦某處(chu)失火(huo)，系統(tong)開(kai)啟(qi)，噴頭噴水(shui)，管道中(zhong)水(shui)流(liu)動，當系統(tong)水(shui)通過指(zhi)示器(qi)(qi)時(shi)，沖(chong)擊水(shui)流(liu)指(zhi)示器(qi)(qi)的(de)葉(xie)片向(xiang)水(shui)流(liu)方(fang)向(xiang)偏移傾(qing)斜，動作桿擠(ji)壓超小型電(dian)(dian)(dian)氣(qi)開(kai)關，電(dian)(dian)(dian)觸點(dian)閉合，給(gei)出(chu)電(dian)(dian)(dian)接點(dian)信號。即水(shui)流(liu)信號換成(cheng)電(dian)(dian)(dian)信號，啟(qi)動電(dian)(dian)(dian)報警系統(tong)或(huo)直接啟(qi)動消防水(shui)泵等(deng)電(dian)(dian)(dian)氣(qi)設備，并(bing)在控(kong)(kong)制臺上顯示出(chu)該區(qu)（或(huo)層）所(suo)控(kong)(kong)制的(de)某處(chu)發(fa)生火(huo)情，并(bing)發(fa)出(chu)警報，這樣噴淋主(zhu)泵進(jin)行(xing)連續供水(shui)滅(mie)火(huo)。水(shui)流(liu)停止時(shi)間中(zhong)片和動作桿復位，開(kai)關觸點(dian)斷開(kai)，電(dian)(dian)(dian)接點(dian)信號消除。
