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，一般高品質排煙管道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，排煙管道安裝在(zai)排煙管道中發生(sheng)火災(zai)時控制中心(xin)給出電信號(hao)使(shi)其打開(kai)排煙，當溫度到達280時易熔合(he)金(jin)熔化(hua)閥門(men)關(guan)閉(bi)，是一種二次動作的閥門(men)。
