6, the end of the pipe hanger should meet the requirements of regulating the height of the wind pipe. After the hanger is made well, it is installed according to the arrangement position of the wind pipe. The distance between the horizontal wind pipe is not more than 3m, and the vertical wind pipe is not more than 4m.

7、镀锌风管支吊架、防火阀、电动风阀等部件安装处必须单独设支吊架处,一般风管每隔3米左右设支吊架一个,支吊架的作法可参照采暖通风国家标准。

7. The installation of the supporting hanger, the fire valve, the electric wind valve and other parts of the galvanized wind pipe must be set up separately, and the general wind pipe is set up every 3 meters, and the method of supporting the hanger can refer to the national standard of heating and ventilation.

8、风管支、吊架不得设置在风口、阀门、检查门及自控机构处。吊杆不得直接固定在法兰上。每隔两个吊架用角铁设置一个防晃动支架。
