水流指示器閥門

水(shui)(shui)流(liu)指示(shi)器(qi)主要(yao)安裝在(zai)(zai)(zai)分(fen)(fen)層或分(fen)(fen)區(qu)(qu)域的(de)自動(dong)噴(pen)淋系統(tong)(tong)的(de)水(shui)(shui)平干道(dao)上，在(zai)(zai)(zai)自動(dong)噴(pen)淋系統(tong)(tong)中(zhong)起著檢測和指示(shi)報警區(qu)(qu)域的(de)作用。一旦某處失火(huo)，系統(tong)(tong)開啟(qi)，噴(pen)頭噴(pen)水(shui)(shui)，管道(dao)中(zhong)水(shui)(shui)流(liu)動(dong)，當系統(tong)(tong)水(shui)(shui)通(tong)過指示(shi)器(qi)時，沖擊水(shui)(shui)流(liu)指示(shi)器(qi)的(de)葉(xie)片(pian)(pian)向水(shui)(shui)流(liu)方向偏移傾斜，動(dong)作桿擠壓超小(xiao)型電(dian)(dian)(dian)氣開關，電(dian)(dian)(dian)觸(chu)點(dian)閉合，給出(chu)(chu)(chu)電(dian)(dian)(dian)接(jie)點(dian)信(xin)號。即水(shui)(shui)流(liu)信(xin)號換成(cheng)電(dian)(dian)(dian)信(xin)號，啟(qi)動(dong)電(dian)(dian)(dian)報警系統(tong)(tong)或直接(jie)啟(qi)動(dong)消(xiao)防水(shui)(shui)泵等電(dian)(dian)(dian)氣設備(bei)，并(bing)在(zai)(zai)(zai)控(kong)制(zhi)臺(tai)上顯示(shi)出(chu)(chu)(chu)該區(qu)(qu)（或層）所控(kong)制(zhi)的(de)某處發生火(huo)情，并(bing)發出(chu)(chu)(chu)警報，這樣噴(pen)淋主泵進行(xing)連(lian)續(xu)供(gong)水(shui)(shui)滅火(huo)。水(shui)(shui)流(liu)停止時間中(zhong)片(pian)(pian)和動(dong)作桿復位，開關觸(chu)點(dian)斷(duan)開，電(dian)(dian)(dian)接(jie)點(dian)信(xin)號消(xiao)除。
