水流指示器閥門

水(shui)(shui)流(liu)(liu)指(zhi)示(shi)(shi)(shi)器(qi)(qi)(qi)主(zhu)要安裝在分層或分區(qu)域的自動噴淋(lin)系統的水(shui)(shui)平干道上，在自動噴淋(lin)系統中(zhong)起(qi)著檢測和指(zhi)示(shi)(shi)(shi)報警區(qu)域的作(zuo)用。一旦某(mou)處失火(huo)(huo)，系統開啟(qi)(qi)，噴頭噴水(shui)(shui)，管道中(zhong)水(shui)(shui)流(liu)(liu)動，當(dang)系統水(shui)(shui)通過指(zhi)示(shi)(shi)(shi)器(qi)(qi)(qi)時，沖擊水(shui)(shui)流(liu)(liu)指(zhi)示(shi)(shi)(shi)器(qi)(qi)(qi)的葉(xie)片向(xiang)水(shui)(shui)流(liu)(liu)方向(xiang)偏移傾(qing)斜，動作(zuo)桿擠壓超小(xiao)型電(dian)(dian)氣開關，電(dian)(dian)觸點(dian)(dian)(dian)閉合，給出(chu)(chu)電(dian)(dian)接點(dian)(dian)(dian)信號(hao)。即水(shui)(shui)流(liu)(liu)信號(hao)換成電(dian)(dian)信號(hao)，啟(qi)(qi)動電(dian)(dian)報警系統或直接啟(qi)(qi)動消(xiao)防水(shui)(shui)泵等電(dian)(dian)氣設備(bei)，并在控制臺上顯示(shi)(shi)(shi)出(chu)(chu)該區(qu)（或層）所控制的某(mou)處發(fa)生火(huo)(huo)情，并發(fa)出(chu)(chu)警報，這(zhe)樣噴淋(lin)主(zhu)泵進行連續供水(shui)(shui)滅火(huo)(huo)。水(shui)(shui)流(liu)(liu)停(ting)止時間中(zhong)片和動作(zuo)桿復位，開關觸點(dian)(dian)(dian)斷(duan)開，電(dian)(dian)接點(dian)(dian)(dian)信號(hao)消(xiao)除。
