涪陵推薦配件價格

1、70℃防火閥用在空調送風、通風系統管道上；平時常開，發生火災時關閉，聯鎖風機，使風機關閉；2、280℃防火閥用在排煙系統管道上，平時常開，發生火災時排煙，當煙氣溫度達到280度時，防火閥關閉，聯鎖風機關閉；3、280℃防火閥應為常開，又叫高溫防火閥，一般推薦配件安裝在有高溫環境的通風管道中，當溫度到達280℃后易熔合金熔化，閥門關閉，同時可以用24V電信號控制。如果說是280排煙防火閥應為常閉，配件安(an)裝在排(pai)(pai)煙(yan)管道中(zhong)發(fa)生火災時(shi)控(kong)制中(zhong)心(xin)給出電信號使其打開排(pai)(pai)煙(yan)，當溫(wen)度(du)到達280時(shi)易熔(rong)合金熔(rong)化閥(fa)門(men)關(guan)閉(bi)，是一(yi)種(zhong)二次動(dong)作(zuo)的閥(fa)門(men)。
