Usually, the smoke hood we set in the kitchen is a partial smoke exhaust mode. In the process of design and installation, the first thing is to ensure the air speed of the smoke exhaust port. We can measure the total air volume required by the smoke exhaust hood according to the air speed of the smoke exhaust port. Then the overall air volume is used to calculate the cross section of the smoke exhaust pipe so as to determine the overall height of the kitchen smoke exhaust pipe.

　　91视频APP污在进行对91视频网站观看罩设计安装时，要注意91视频网站观看罩所安装的墙面需要有足够好的构造以及材料。91视频网站观看的91视频成人网站和出风口的墙面的开口处可以使用砌筑的带洞的混领土快或者提前埋下钢管注意留个洞，好使用空心砖来进行安装，操作方式和普通的墙面一样。假使墙面牢固的话，就需要用木板或者其他的材料进行加固。

　　When we design and install the smoke hood, we should pay attention to the good construction and material of the wall installed by the smoke hood. The smoke exhaust pipe and the wall opening of the air outlet can be used to build the mixed territory with holes quickly or bury the steel pipe ahead of time. It is better to use hollow bricks for installation. The operation mode is the same as the ordinary wall. If the walls are strong, they need to be reinforced with wood or other materials.

　　91视频网站观看罩的安装应该从外墙穿内墙，在房间的外面91视频网站观看罩的出口处安装一些防污染和避风的构件，并用竖向的烟道和油烟机连接，它的面积可以依据断面所负担的排气量的决定，通常设置在燃气灶的上方少65厘米的地方。当91视频网站观看罩发生了漏油或者漏风的情况，在设置91视频成人网站时需要选择防火的材料，在对91视频成人网站进行安装时要设置防火的阀门，要可以保证91视频网站观看罩在使用时发生火灾防火阀门可以自己关闭。

　　Installation of smoke hood should go through the outer wall to the inner wall, install some anti-pollution and anti-wind components at the exit of the smoke hood outside the room, and connect it with a vertical flue and a lampblack machine. Its area can be determined by the amount of exhaust gas borne by the section, and it is usually located at least 65 centimeters above the gas stove. When the exhaust hood leaks oil or air, it is necessary to choose fire-proof materials when installing the pipeline. When installing the pipeline, it is necessary to set fire-proof valves, which can ensure that the fire-proof valves can be closed by themselves when the exhaust hood is in use.
