排煙防(fang)火閥(fa)的(de)工作原理
排煙防火閥是一種采用(yong)碳鋼板制(zhi)(zhi)造的金屬(shu)多(duo)葉結構的產品(pin),一般(ban)安裝在排(pai)煙(yan)(yan)系(xi)統的風管上(shang),平時(shi)(shi)(shi)常(chang)閉(bi)(bi),發生火(huo)災時(shi)(shi)(shi),煙(yan)(yan)感探頭(tou)發出火(huo)警信號,控制(zhi)(zhi)中心通DC24V電(dian)給閥體上(shang)電(dian)磁鐵,使(shi)閥門(men)(men)迅速(su)打(da)開(kai),或人工(gong)手(shou)動(dong)打(da)開(kai)閥門(men)(men)進(jin)行排(pai)煙(yan)(yan),當(dang)煙(yan)(yan)道溫度達(da)(da)到(dao)280攝氏(shi)度時(shi)(shi)(shi),自(zi)動(dong)關(guan)閉(bi)(bi),手(shou)動(dong)復(fu)(fu)位。??排(pai)煙(yan)(yan)防火(huo)的性能:??1.電(dian)訊(xun)號DC24V±將閥門(men)(men)打(da)開(kai);??2.手(shou)動(dong)使(shi)閥門(men)(men)打(da)開(kai);??3.手(shou)動(dong)復(fu)(fu)位??4.溫度達(da)(da)到(dao)280攝氏(shi)度時(shi)(shi)(shi),閥門(men)(men)控制(zhi)(zhi)點(dian)熔斷(duan)關(guan)閉(bi)(bi)。??5.閥門(men)(men)動(dong)作后,輸出電(dian)訊(xun)號根據用(yong)戶需要可與其他設備(bei)聯鎖(suo)。??排(pai)煙(yan)(yan)防火(huo)閥及多(duo)葉排(pai)煙(yan)(yan)口等產品(pin)廣泛適用(yong)于各種商業建筑、廠礦、地鐵等等場所(suo)的消防排(pai)煙(yan)(yan)系(xi)統。
