一、副煙道務(wù)必保留

First, the flue must be retained

每家的廚房里都有煙道，同時煙道也有主副之分，主煙道貫穿整個樓體，而副煙道是相對獨立的。一般家里的油煙會先到副煙道里，然后再通過隔板上的孔進入主煙道，這樣可保證每戶的油煙是隔離開來的。而如果將副煙道直接連接主煙道，就會由于壓力過低而導(dǎo)致倒煙或串煙現(xiàn)象。

Each kitchen has a flue, and the flue also has the main and Deputy points, the main flue through the entire building, and the flue is relatively independent. Generally, the smoke at home will go to the flue first, and then into the main flue through the hole on the partition board, so that the smoke can be isolated from each household. And if the side flue is directly connected with the main flue, will lead to smoke or smoke phenomenon due to low pressure.

二、施工細(xì)節(jié)要注意

Two, construction details should pay attention to

，選擇抽油煙機安裝的位置十分重要。管道越短越好。一些業(yè)主會為了美觀，把管道拉得比較長，這樣一來，關(guān)掉油煙機后，管道里還會集聚很多油煙排不出去，再倒回室內(nèi)。另外，為了不破壞原有的主副煙道，其開口方向不是隨意可以改的，一定要打在副煙道里面。

First, it is important to select the location of the range hood. The shorter the pipe, the better. Some owners in order to pull the pipe appearance, is relatively long, so, turn off the lampblack machine, the pipe will gather a lot of fumes discharged out, and then back to the room. In addition, in order not to destroy the original main and auxiliary flue, the direction of its opening is not optional, can be modified, must be hit in the flue.

三、窗戶排煙注意

Three, window smoke evacuation, pay attention to safety

一些業(yè)主為了避免串煙問題，放棄原有煙道，直接在窗戶上開孔排煙，這樣做是可以的，但有幾點需要注意。

Some owners in order to avoid smoke problems, give up the original flue, directly in the window opening smoke, this is OK, but there are several points need attention.

在窗戶或墻面開洞之前一定要經(jīng)過物業(yè)的同意;其次注意問題，一般排煙管末端是金屬材質(zhì)的，如果開的洞太小，金屬傳熱可能會使玻璃炸裂，傷及行人，且煙管通向窗外，強勁的北風(fēng)對著吹會導(dǎo)致油煙倒灌。將管道伸出去以后把管道往下窩，這樣還可以避免下雨時雨水流進管道，并把風(fēng)擋在外面。

First, before the window or wall openings must go through the consent of the property; second Caution!, general smoke at the end of the tube is made of metal material, if the hole is too small, the metal heat transfer may cause cracking of glass, and pedestrians, and the smoke pipe to the outside, the strong north wind blows will lead to soot intrusion. It's better to put the pipe out and put the pipe down, so that it can avoid the rain and water flowing into the pipe and keep the windshield outside.

四、止逆閥門勤更換

Four, check valve replacement

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，油煙機的止逆閥效果不是很明顯，而在煙道安裝止逆閥可以保護油煙機，使煙道里的煙不會向管道和抽油煙機內(nèi)倒灌。不過，安裝止逆閥后要定期清洗，否則會使止逆閥呈打開狀態(tài)，失去效果，而且煙道止逆閥兩年左右就更換一次。

If you have the side flue removed, or need to better prevent smoke, then use flue non-return valve. Normally, the effect of the check valve of the range hood is not very obvious, and the check valve in the flue can protect the hood, so that the smoke in the flue can not flow backward to the pipe and the range hood. However, after the installation of check valve should be cleaned regularly, otherwise it will open the check valve, lost effect, and the flue check valve is best to replace it two years or so.
