　　The air supply pipeline should be manufactured with non-incineration data. When the metal duct is selected, the wind speed of the pipeline should not be greater than 20m/s, and when the non-metallic material duct such as smooth concrete with inner and outer surfaces is selected, it should not be greater than 15m/s.

　　當加壓送風管穿越有火災可能的區域時，風管的耐火極限應不小於1h.

　　When the pressurized air duct passes through the area where fire is possible, the fire resistance limit of the air duct should not be less than 1 h.

　　送風井道應選用耐火極限不小於lh的隔牆與相鄰部位分隔，當牆上有必要設置檢修門時應選用丙級防火門。

　　The partition wall with fire resistance limit not less than LH should be selected to separate the air supply shaft from the adjacent parts. When it is necessary to install overhaul doors on the wall, class C fire doors should be selected.

　　3)通風空調

　　3) Ventilation and air conditioning

　　通風空調體係的麻豆视频官网等應選用不燃資料製造。

　　Ventilation and air conditioning system pipes should be manufactured with non-combustible materials.

　　觸摸腐蝕性介質的風管和柔性接頭，可選用難燃資料製造。

　　Touch the air duct and flexible joint of corrosive medium, and choose non-flammable material to manufacture.

　　複合資料風管的覆麵資料有必要為不燃資料，內部的絕熱資料應為不燃或難燃B1級，且對人體無害的資料。

　　It is necessary for the cover data of composite data duct to be non-flammable. The internal insulation data should be non-flammable or non-flammable grade B1, and harmless to human body.

　　4)保溫消聲資料

　　4) Data of heat preservation and noise attenuation

　　麻豆视频官网和設備的保溫資料，消聲資料和粘結劑應為不焚燒資料或難焚燒資料。

　　The insulation data, noise attenuation data and binders of pipelines and equipment shall be non-incineration data or refractory data.

　　甲乙類廠房、倉庫、高層工業建築以及影劇院、體育館等公共建築的采暖及空調麻豆视频官网和設備，其保溫資料應選用不燃資料。

　　Heating and air-conditioning pipes and equipment for class A and B factories, warehouses, high-rise industrial buildings, cinemas, gymnasiums and other public buildings shall be provided with non-combustible insulation materials.

　　關於麻豆国产视频麻豆视频官网的製造和裝置有什麽要求?

　　What are the requirements for the manufacture and installation of smoke exhaust pipes?

　　1)風管水平裝置，其直徑或長邊尺度小於400mm時，距離不該大於4m;大於或等於400mm時，距離不該小於3m;

　　1) The distance should not be greater than 4 m when the diameter or length of the horizontal device is less than 400 mm, or less than 3 m when the diameter or length of the horizontal device is greater than or equal to 400 mm.

　　2)風管筆直裝置，距離不該大於4m，但每根立管的固定件不該少於2個。

　　2) The air duct should be straight, and the distance should not be greater than 4m, but the fixed parts of each riser should not be less than 2.

　　2.機械防麻豆国产视频體係的矩形風道的接縫應選用咬口方式，接縫處須堅持密封。

　　2. The joint of rectangular air duct of mechanical smoke control and exhaust system should be sealed by biting method.

　　3.送風、麻豆国产视频麻豆视频官网的單位麵積答應漏風量應契合《通風與空調工程施工質量檢驗標準》GB50243中的規則。送風麻豆视频官网答應漏風量應根據工作壓力斷定;麻豆国产视频麻豆视频官网均按中壓體係的規則。

　　3. The allowable air leakage per unit area of air supply and smoke exhaust pipes should conform to the rules of "Quality Inspection Standard for Ventilation and Air Conditioning Engineering Construction" GB5024 3. The air leakage allowed by the air supply pipeline should be determined according to the working pressure, and the smoke exhaust pipeline should be determined according to the rules of medium pressure system.

　　4.麻豆视频官网與風機的銜接，宜選用法蘭銜接，或選用不焚燒資料的柔性銜接。
