水流指(zhi)示器閥門(men)

水(shui)(shui)流指(zhi)示(shi)器(qi)主(zhu)要(yao)安裝在分層(ceng)或分區域(yu)的(de)自動(dong)(dong)噴(pen)淋系統(tong)(tong)的(de)水(shui)(shui)平干(gan)道上(shang)(shang)，在自動(dong)(dong)噴(pen)淋系統(tong)(tong)中(zhong)(zhong)起(qi)著(zhu)檢(jian)測(ce)和指(zhi)示(shi)報(bao)警(jing)區域(yu)的(de)作(zuo)用(yong)。一旦某處失火(huo)(huo)，系統(tong)(tong)開(kai)啟(qi)，噴(pen)頭噴(pen)水(shui)(shui)，管(guan)道中(zhong)(zhong)水(shui)(shui)流動(dong)(dong)，當系統(tong)(tong)水(shui)(shui)通過指(zhi)示(shi)器(qi)時，沖擊(ji)水(shui)(shui)流指(zhi)示(shi)器(qi)的(de)葉片向水(shui)(shui)流方向偏移傾(qing)斜(xie)，動(dong)(dong)作(zuo)桿擠壓(ya)超小型電(dian)(dian)氣開(kai)關(guan)，電(dian)(dian)觸(chu)點閉合，給出(chu)(chu)電(dian)(dian)接點信(xin)號。即水(shui)(shui)流信(xin)號換成(cheng)電(dian)(dian)信(xin)號，啟(qi)動(dong)(dong)電(dian)(dian)報(bao)警(jing)系統(tong)(tong)或直接啟(qi)動(dong)(dong)消防(fang)水(shui)(shui)泵(beng)等電(dian)(dian)氣設(she)備(bei)，并在控制(zhi)臺上(shang)(shang)顯示(shi)出(chu)(chu)該區（或層(ceng)）所(suo)控制(zhi)的(de)某處發生(sheng)火(huo)(huo)情(qing)，并發出(chu)(chu)警(jing)報(bao)，這樣噴(pen)淋主(zhu)泵(beng)進行連續供水(shui)(shui)滅火(huo)(huo)。水(shui)(shui)流停止時間中(zhong)(zhong)片和動(dong)(dong)作(zuo)桿復位(wei)，開(kai)關(guan)觸(chu)點斷開(kai)，電(dian)(dian)接點信(xin)號消除。
