在通风管道的迎风侧安装防火阀的好处

发布时间:2017/11/24

  保温性能 镀锌薄钢板风管:导热系数很大(为60.4 W/m·K) ,无保温性能,必须另外加包保温层及保护层。

  Thermal insulation performance of galvanized thin steel pipe: thermal conductivity is large (60。4 W/m / K), no thermal insulation performance, must add additional insulation layer and protective layer。

  1)风阀安装前应检查框架结构是否牢固,调节、制动、定位等装置是否准确灵活。

  1) before the installation of the air valve, check whether the frame structure is firm, the adjustment, braking, positioning and other devices are accurate and flexible.

  2)风阀的安装同风管的安装,将其法兰与风管或设备的法兰对正,加上密封垫片,上紧螺栓,使其与风管或设备连接牢固、严密。

  3)风阀安装时,应使阀件的操纵装置便于人工操作。其安装方向应与阀体外壳标注的方向一致。

  3) when the air valve is installed, the valve handling device should be operated manually. The installation direction should be consistent with the direction of the valve body marking.

  4)安装完的风阀,应在阀体外壳上有明显和准确的开启方向、开启程度的标志。

天天乐棋牌  4) the installation of the air valve should be marked on the valve body shell clear and accurate opening direction, opening degree。

  5)防火阀的易熔片应安装在风管的迎风侧,其熔点温度应符合设计要求。

  5) fusible alloy fire valve should be installed on the windward side of the wind pipe, the melting temperature should meet the design requirements.

  在风管加工处保温厚度不易保证或无保温,将产生冷桥现象,风管壁面保温层的覆盖均匀度有时也会因安装净空不足而不易保证。 无机玻璃钢风管:导热系数大(为0。5W/m·K) ,无保温性能,必须另外加包保温层及保护层,保温层特性同镀锌薄钢板风管。

  In the air duct processing department, the insulation thickness is not easy to guarantee or no heat preservation, the cold bridge phenomenon will occur, and the uniformity of the insulation layer of the wall of the air duct will sometimes be difficult to guarantee because of insufficient installation clearance. Inorganic glass fiber reinforced plastic air duct: large thermal conductivity (0.5W/m = K), no thermal insulation performance, must add additional insulation layer and protective layer, insulation layer characteristics with galvanized thin steel pipe duct.

  复合玻纤板风管:导热系数小(平均温度24℃时是0.029W/m·K,70℃时是0.04W/m·K) ,特别是外表复合铝箔布具有很高的热反射能力。

  Composite glass fiber board: the coefficient of thermal conductivity is small (average temperature is 24 K, 0.029W/m, K, 0.04W/m at 70 degrees), especially the appearance of composite aluminum foil cloth has high heat reflection ability.
