style="text-indent:25px">什么是防火門呢？防火門，是用來維持走火通道的耐火完整性及提供逃生途徑的門。其目的是要確保在一段合理時間（通常是逃生時間）內，保護走火通道內正在逃生的人免受火災的威脅，包括阻隔濃煙及熱力。防火門的作用主要是在消防重點部位起到防火隔離的作用。防火門是建筑物防火分隔的措施之一，通常用在防火墻上，樓梯間出入口或管道井開口部位，要求能隔煙、火。防火門對防止煙、火的擴散和曼延、減少損失起重要作用。防火門按照開啟方狀態(tài)分為常閉防火門和常開防火門。常閉防火門平常在閉門器的作用下處于關閉狀態(tài)。因此，當發(fā)生火災時能起到阻止火勢煙氣曼延；常開防火門平時在閉門器的作用下處于開啟狀態(tài)，當發(fā)生火災時，自動釋放開關，防火閉門器在閉門器和順位器的作用下關閉。安裝卷簾門的洞口上部不得設有通風管、水管等。甘肅提升門生產</p><p
