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.

　　窗戶排煙注意

　　Safety of smoke exhaust from windows

　　一些業(yè)主為了避免串煙問(wèn)題，放棄原有煙道，直接在窗戶上開孔排煙，這樣做是可以的，但有幾點(diǎn) 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.

　　濟(jì)南排煙罩廠家在窗戶或墻面開洞之前一定要經(jīng)過(guò)物業(yè)的同意;其次注意問(wèn)題，一般排煙管末端是金屬材質(zhì)的，如果開的洞太小，金屬傳熱可能會(huì)使玻璃炸裂，傷及行人，且煙管通向窗外，強(qiáng)勁的北風(fēng)對(duì)著 吹會(huì)導(dǎo)致油煙倒灌。好將管道伸出去以后把管道往下窩，這樣還可以避免下雨時(shí)雨水流進(jìn)管道， 并把風(fēng)擋在外面。

　　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.

　　止逆閥門勤更換

　　Frequent replacement of check valves

　　如果已經(jīng)把副煙道拆除，或是需要防止倒煙的效果更好，那么使用煙道止逆閥。一般情況下，油煙機(jī)的止逆閥效果不是很明顯，而在煙道安裝止逆閥可以保護(hù)油煙機(jī)，使煙道里的煙不會(huì)向管道和抽油煙機(jī)內(nèi)倒灌。不過(guò)，安裝止逆閥后要定期清洗，否則會(huì)使止逆閥呈打開狀態(tài)，失去效果，而且煙道止逆閥好兩年左右就更換一次。

　　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.
