重慶推薦風機通風管價格

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，一般推薦風機通風管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，風機通風管安裝在排煙管(guan)道中(zhong)發(fa)生火災時控制中(zhong)心給出(chu)電信號(hao)使(shi)其(qi)打(da)開排煙，當溫度到(dao)達(da)280時易(yi)熔(rong)合金熔(rong)化(hua)閥門關閉(bi)，是一種二次(ci)動(dong)作的(de)閥門。
