          隨著社會的發展,很多家庭在廚房里用自己的窗戶來排煙,導致樓下做飯,樓上冒煙。所以家庭裝飾時,廚房煙囪裝飾顯得很重要,一旦出現不合理,就會形成反味現象,對家庭生活形成影響。
          With the development of society, many families use their own windows to smoke in the kitchen, resulting in cooking downstairs and smoking upstairs. So when the family decorates, the kitchen chimney decorates appears very important, once appears unreasonable, will form the counter taste phenomenon, forms the influence to the family life.
          1)通風管
          1) ventilation pipe
          通風管體、結構、固定數據、密封數據、柔性接頭的制造需要選用不燃材料。當吊頂內有燃料時,吊頂內的通風管道應采用非燃燒材料絕緣,并與燃料保持不小于150mm的距離。
          Non combustible materials shall be selected for the manufacturing of ventilation pipe body, structure, fixed data, sealing data and flexible joint. When there is fuel in the ceiling, the ventilation pipe in the ceiling shall be insulated with non combustible materials and kept at a distance of not less than 150 mm from the fuel.
          2)正壓送風管道
          2) positive pressure air supply pipe
          供氣管道應采用非焚燒材料。選用金屬風道時,管道風速不宜大于20m/s。選用內表面光滑的混凝土等非金屬材料風道時,應不大于15m/s。
          The gas supply pipeline shall be made of non incineration materials. When selecting metal air duct, the wind speed of the pipeline should not be greater than 20 m / s. When selecting the air duct of non-metallic materials such as concrete with smooth inner surface, it shall not be more than 15m / s.
          增壓送風管道通過可能發生火災的區域時,送風井的耐火極限應不小于1h。送風軸應與相鄰部件分開,耐火極限不小于lh。
          When the pressurized air supply pipe passes through the area where fire may occur, the fire resistance limit of the air supply shaft shall not be less than 1h. The air supply shaft shall be separated from the adjacent parts, and the fire resistance limit shall not be less than LH.
        山東通風管道
          通風和空調
          Ventilation and air conditioning
          通風和空調系統應采用不燃材料。
          The ventilation and air conditioning system shall be made of incombustible materials.
          山東通風管道接觸腐蝕性介質的風道與柔性接頭,可采用耐火材料制成。復合數據風道的覆蓋數據必須為不燃數據,山東風道的絕熱數據必須為不燃或不燃B1級,且對人體無害。
          The air duct and flexible joint of Shandong ventilation pipe contacting corrosive medium can be made of refractory. The coverage data of composite data air duct must be non combustible data, and the insulation data of Shandong air duct must be non combustible or non combustible Class B1, which is harmless to human body.
          通風管道的制造和安裝有什么要求?
          What are the requirements for the manufacture and installation of ventilation pipes?
          1)風管水平裝置直徑或長度小于400mm,距離不得大于4m;當大于或等于400mm時,距離不得小于3m;
          1) the diameter or length of air duct horizontal device shall be less than 400mm, and the distance shall not be greater than 4m; when it is greater than or equal to 400mm, the distance shall not be less than 3m;
          2)氣管矯直裝置,距離不應大于4m,但各立管的固定件不應小于2個。
          2) gas pipe straightening device, the distance shall not be more than 4m, but the fixed parts of each riser shall not be less than 2.
          2. 機械防排煙系統矩形風道接頭應咬傷,并密封。
          2. The joint of rectangular air duct of mechanical smoke control system shall be bitten and sealed.
          3.送風風道單位面積應按照《通風空調工程施工質量檢驗標準》GB50243的規定允許漏風。供氣管道允許的漏風量根據工作壓力確定;通風管道符合中壓系統的規則。
          3. The unit area of air supply duct shall be allowed to leak according to the provisions of GB50243 standard for construction quality inspection of ventilation and air conditioning engineering. The allowable air leakage of the air supply pipeline shall be determined according to the working pressure; the ventilation pipeline shall conform to the rules of the medium pressure system.
