专注通风管道加工·排烟罩

　　It is very important for Jinan smoke exhaust pipeline technicians to choose the installation position of the smoke exhaust hood. The shorter the pipe, the better. Some owners will pull the pipeline longer for the sake of beauty. In this way, after turning off the lampblack machine, there will be a lot of lampblack gathered in the pipeline, which can not be exhausted, and then poured back into the room. In addition, in order not to destroy the original main and auxiliary flue, the opening direction can not be changed at will, and must be hit in the secondary flue.

　　窗户排烟注意

　　Safety of smoke exhaust from windows

　　一些业主为了避免串烟问题，放弃原有烟道，直接在窗户上开孔排烟，这样做是可以的，但有几点 需要注意。

　　In order to avoid the problem of smoking, some owners abandon the original flue and directly open a hole in the window to exhaust smoke. This is possible, but there are several points to be noted.

　　济南排烟罩厂家在窗户或墙面开洞之前一定要经过物业的同意;其次注意问题，一般排烟管末端是金属材质的，如果开的洞太小，金属传热可能会使玻璃炸裂，伤及行人，且烟管通向窗外，强劲的北风对着 吹会导致油烟倒灌。好将管道伸出去以后把管道往下窝，这样还可以避免下雨时雨水流进管道， 并把风挡在外面。

　　Firstly, Jinan smoke hood manufacturer must pass the agreement of the property before opening the window or wall; secondly, pay attention to the safety problem. Generally, the end of the smoke pipe is made of metal material. If the opening is too small, the metal heat transfer may cause the glass to burst and injure the pedestrians. Moreover, the smoke pipe leads out of the window, and the strong northerly wind will cause the backflow of the smoke. It's better to stick the pipe out and put it down to the nest, so as to avoid rainwater flowing into the pipe and keep the wind out when it rains.

　　止逆阀门勤更换

　　Frequent replacement of check valves

　　如果已经把副烟道拆除，或是需要防止倒烟的效果更好，那么使用烟道止逆阀。一般情况下，油烟机的止逆阀效果不是很明显，而在烟道安装止逆阀可以保护油烟机，使烟道里的烟不会向管道和抽油烟机内倒灌。不过，安装止逆阀后要定期清洗，否则会使止逆阀呈打开状态，失去效果，而且烟道止逆阀好两年左右就更换一次。

　　If the auxiliary flue has been demolished, or if the effect of preventing smoke pouring is better, then use the flue check valve. Generally, the effect of the check valve of the lampblack machine is not very obvious, but installing the check valve in the flue can protect the lampblack machine, so that the smoke in the flue will not be poured back into the pipeline and the lampblack machine. However, check valves should be cleaned regularly after installation, otherwise the check valves will be open and ineffective, and the flue check valves should be replaced once every two years or so.
