水流指示器(qi)閥(fa)門

水(shui)(shui)(shui)(shui)流(liu)指(zhi)示(shi)器主要安裝在(zai)(zai)分(fen)層或(huo)分(fen)區(qu)域的(de)自動(dong)噴(pen)(pen)淋(lin)系統(tong)(tong)(tong)的(de)水(shui)(shui)(shui)(shui)平干道上，在(zai)(zai)自動(dong)噴(pen)(pen)淋(lin)系統(tong)(tong)(tong)中起著(zhu)檢測和指(zhi)示(shi)報(bao)警區(qu)域的(de)作用。一旦某處(chu)失火(huo)，系統(tong)(tong)(tong)開啟，噴(pen)(pen)頭(tou)噴(pen)(pen)水(shui)(shui)(shui)(shui)，管道中水(shui)(shui)(shui)(shui)流(liu)動(dong)，當系統(tong)(tong)(tong)水(shui)(shui)(shui)(shui)通過指(zhi)示(shi)器時，沖擊水(shui)(shui)(shui)(shui)流(liu)指(zhi)示(shi)器的(de)葉片(pian)向(xiang)水(shui)(shui)(shui)(shui)流(liu)方向(xiang)偏移傾(qing)斜，動(dong)作桿擠壓超(chao)小型電氣開關，電觸點(dian)閉合，給出電接點(dian)信(xin)(xin)號(hao)。即(ji)水(shui)(shui)(shui)(shui)流(liu)信(xin)(xin)號(hao)換(huan)成電信(xin)(xin)號(hao)，啟動(dong)電報(bao)警系統(tong)(tong)(tong)或(huo)直接啟動(dong)消防水(shui)(shui)(shui)(shui)泵(beng)等(deng)電氣設備，并在(zai)(zai)控制(zhi)臺上顯示(shi)出該區(qu)（或(huo)層）所(suo)控制(zhi)的(de)某處(chu)發生火(huo)情，并發出警報(bao)，這(zhe)樣噴(pen)(pen)淋(lin)主泵(beng)進行連續供(gong)水(shui)(shui)(shui)(shui)滅火(huo)。水(shui)(shui)(shui)(shui)流(liu)停止時間中片(pian)和動(dong)作桿復位，開關觸點(dian)斷(duan)開，電接點(dian)信(xin)(xin)號(hao)消除。
