| 风管的安装 Installation of air duct 1、技术要求，明装水平度 每米≤3mm ，总偏差≤20mm；垂直度每米≤2mm，总偏差≤20mm；暗装，位置应正确，无明显偏差。 1, the technical requirements, with the level of per meter is less than or equal to 3mm, the total deviation is not greater than 20mm; verticality per meter is less than or equal to 2mm, the total deviation is not greater than 20mm; concealed installation location should be correct, no significant deviation. 2、安装顺序：先干管后支管，安装方法：根据实际情况确定。 2, installation order: first dry pipe, branch pipe, installation method: according to the actual situation. 可以在地面上连成一定的长度，然后整体吊装，一般可接长至10--12米左右，用倒链或升降机将风管吊到支架上（比较重的风管），也可以把风管一节一节地放在支架上逐节连接。 Can be connected to a certain length on the ground, and then the integral hoisting, generally can be connected to 10--12 meters long, with a chain or lift wind pipe hanging onto the bracket (wind pipe heavier), can also be a section of a wind tube placed on the bracket by section connection. 3、风管穿越需要封闭的防火防爆的墙体或楼板时，应设预埋管或防护套管，其钢板厚度不应小于1.6mm，风管与防护套管之间，应用不燃且对人体无危害的柔性材料封堵。 3, the wind pipe through the need to fire and explosion of the closed wall or floor, should set up the embedded pipe or a protective sleeve, the thickness of the steel plate should not be less than 1.6mm, between the wind pipe and a protective sleeve, flexible material sealing with non combustible and no harm to human body. 4、复合材料风管接缝应牢固，无孔洞和开裂，风管系统安装完毕后，应按系统类别进行严密性检验。 4. The joint of the composite material pipe shall be firm, free of holes and cracks. After the installation of the air duct system, the tightness test shall be carried out according to the type of the system. 风阀的安装 Installation of air valve 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 wind valve, check whether the frame structure is firm, adjust the 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。 2. The installation of the air valve and the installation of the wind pipe, the flange and the air pipe or equipment flange is right, plus sealing gasket, tighten the bolt, so that it is connected with the wind pipe or equipment strong and tight. 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, the installation of air valve, valve handling device should be easy to manual operation, and its installation direction should be marked with the direction of the body shell. 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。 4, the installation of the air valve, the valve body should be marked on the shell and accurate opening direction, the sign of the degree of opening. 防火阀的易熔件应安装在风管的迎风侧，其熔点温度应符合设计要求。 A fusible fireproof valve should be installed on the windward side of the wind pipe, the melting temperature should meet the design requirements. |
