280C防火閥應為常開，又叫高溫防火閥，一般安裝在有高溫環(huán)境的通風管道中，當溫度到達280C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°C排煙防火閥應為常閉，安裝在排煙管道中發(fā)生火災時控制中心給出電信號使其打開排煙，當溫度到達280C時易熔合金熔化閥門關閉是一種二次動作的閥門。風閥，就選無錫雋發(fā)暖通設備有限公司，家長們的信賴之選，歡迎您的來電哦！</p><div

style="text-indent:25px">排煙閥：對于防煙分區(qū)內(nèi)的兼用支風道，排煙閥是常開的，而且由于著火區(qū)的不確定性，該排煙閥又應該是可開、可閉的，因此應采用電動式。任一防煙分區(qū)失火，均可有消防中心控制該區(qū)排煙閥開啟排煙，其他分區(qū)的排煙閥關閉。若防煙分區(qū)內(nèi)支風道不兼用，即在原風道上并聯(lián)一排煙止管，這時排煙支管上的排煙閥是常閉的下并與煙感器聯(lián)動的電磁式手動復位閥門。一般非兼用的排煙系統(tǒng)中的排煙閥亦是如此。排煙口:由排煙閥與百葉風口或板式鳳口組成，用在排煙系統(tǒng)火箭用系統(tǒng)的排煙支管上。無錫雋發(fā)暖通設備有限公司為您提供風閥，有想法可以來我司咨詢！淮安防火風閥定做</p><p
