来源: 日期:2019-11-07 发布人:admin

  随着社会的发展,很多家庭在厨房里用自己的窗户来排烟,导致楼下做饭,楼上冒烟。所以家庭装饰时,厨房烟囱装饰显得很重要,一旦出现不合理,就会形成反味现象,对家庭生活形成影响。
  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)通风管
  1) ventilation pipe
  通风管体、结构、固定数据、密封数据、柔性接头的制造需要选用不燃材料。当吊顶内有燃料时,吊顶内的通风管道应采用非燃烧材料绝缘,并与燃料保持不小于150mm的距离。
  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)正压送风管道
  2) positive pressure air supply pipe
  供气管道应采用非焚烧材料。选用金属风道时,管道风速不宜大于20m/s。选用内表面光滑的混凝土等非金属材料风道时,应不大于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.
  增压送风管道通过可能发生火灾的区域时,送风井的耐火极限应不小于1h。送风轴应与相邻部件分开,耐火极限不小于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.
山东通风管道
  通风和空调
  Ventilation and air conditioning
  通风和空调系统应采用不燃材料。
  The ventilation and air conditioning system shall be made of incombustible materials.
  山东通风管道接触腐蚀性介质的风道与柔性接头,可采用耐火材料制成。复合数据风道的覆盖数据必须为不燃数据,山东风道的绝热数据必须为不燃或不燃B1级,且对人体无害。
  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.
  通风管道的制造和安装有什么要求?
  What are the requirements for the manufacture and installation of ventilation pipes?
  1)风管水平装置直径或长度小于400mm,距离不得大于4m;当大于或等于400mm时,距离不得小于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)气管矫直装置,距离不应大于4m,但各立管的固定件不应小于2个。
  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. 机械防排烟系统矩形风道接头应咬伤,并密封。
  2. The joint of rectangular air duct of mechanical smoke control system shall be bitten and sealed.
  3.送风风道单位面积应按照《通风空调工程施工质量检验标准》GB50243的规定允许漏风。供气管道允许的漏风量根据工作压力确定;通风管道符合中压系统的规则。
  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.
