class="title">詳細說明</p><div id="mbyvcel" class="box"><p><p style="text-indent:25px">防火閥的設置為了阻止火災時火勢和有毒高溫煙氣通過風管蔓延擴大，在通風、空調系統(tǒng)的風管上需設置防火閥。廚房、浴室和廁所等的排風管道與豎井連接時也應采取相應措施防止火勢沿著排風管在各樓層間蔓延。廚房、浴室和廁所等的排風管道與豎井相連時，若無防止回流的措施時應在支管上設置防火閥；當有防止回流的措施時，可不設防火閥。防火閥應能在溫度達到70℃時自動關閉，防火閥一般可采用易熔片式自動關閉，廣西防火閥廠家哪家好，并與風機聯(lián)鎖。防火閥主要是由閥體和執(zhí)行機構組成，閥體由殼體、法蘭、葉片及葉片聯(lián)動機構等組成，執(zhí)行機構由外殼、葉片調節(jié)機構，廣西防火閥廠家哪家好，廣西防火閥廠家哪家好、離合器、溫度熔斷器等組成。防火閥由金屬易熔片和離合器機構來控制葉片的轉動，市場上常見的防火閥有70℃和280℃防火閥。排煙系統(tǒng)的防火閥是在火災是排煙的，煙氣溫度較高。廣西防火閥廠家哪家好</p><div

style="text-indent:25px">在現行標準中，常規(guī)通風空調系統(tǒng)中火閥的工作溫度通常為70℃，通常由通風空調系統(tǒng)的較高溫度確定，比正常運行時的通風空調系統(tǒng)的較高溫度高出25℃左右。正常運行的通風空調系統(tǒng)的溫度一般為45≤50℃，宜設為70℃。這一溫度也與國家標準圖中消防閥的工作溫度和主動噴水滅火系統(tǒng)的啟動溫度有關。但“國家民用建筑工程設計技術措施”暖通空調?！半娫础狈肿C指出，廚房排煙管道在公共建筑與直排氣管的交界處，應設置一個工作溫度為150℃的消防閥。作者認為這條規(guī)則是不恰當的。廣州防火閥哪家強排煙防火閥還適用于通風、空調管道裝在吊頂上，無法用人工手動復位的場合。</p><div

style="text-indent:25px">安裝在通風、空氣調節(jié)系統(tǒng)的送、回風管道上，平時呈開啟狀態(tài)，火災時當管道內煙氣溫度達到70℃時關閉，起隔煙阻火作用，主要為了保證防火完整性。對于防火類閥門的控制和具備的功能，防火規(guī)范和防排煙標準并未做明確的說明，只能在閥門規(guī)范里面看到只言片語，對于防火閥的功能應該以實際工程需求為主。防火規(guī)范附表中有“防煙防火閥”的表述，但是在閥門規(guī)范和消防認證中并未出現“防煙防火閥”的名稱，建議廢除的這個叫法，此附表是從老建規(guī)上直接搬過來的，應該說已經不適合現在的閥門體系了。結合消防認證產品報告和實際的工程需求，梳理出4種防火閥，應該足夠在工程中應用。在空調體系的風道上，設備排煙防火閥的目的是當發(fā)生火災時能靈敏堵截運送的氣流。</p><div

style="text-indent:25px">風空調系統(tǒng)中防火閥的設置與選用風管穿越防火分區(qū)處，穿越通風、空調機房及重要的或火災危險性大的房間隔墻和樓板處；垂直風管與每層水平風管交接處的水平管段上應設防火閥，但多層建筑的每個防火分區(qū)其通風、空調系統(tǒng)均**設置時，則該防火分區(qū)內的水平風管與垂直總管的交接處可不設防火閥；穿越變形縫處的兩側風管上各設一個。上述部位的防火閥,平時常開，當火災中其溫度達到70℃時，則自動關閉。防火閥應靠近防火分隔處設置，且應單獨設支、吊架。當防火閥暗裝時，應在安裝部位設置檢修口。3C防火閥通常能夠裝置于空調設備如新風機組、空調機組等出風口的送風主風道上。廣西防火閥廠家哪家好</p><p
