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(shí)煙道也有主副之分，主煙道貫穿整個(gè)樓體，而副煙道是相對(duì)獨(dú)立的。一般家里的油煙會(huì)先到副煙道里，然后再通過(guò)隔板上的孔進(jìn)入主煙道，這樣可保證每戶的油煙是隔離開(kāi)來(lái)的。而如果將副煙道直接連接主煙道，就會(huì)由于壓力過(guò)低而導(dǎo)致倒煙或串煙現(xiàn)象。

Each kitchen has a flue, while the flue is also the main sub points, the main flue throughout the building body, while the auxiliary flue is relatively independent. General home cooking fume will be first to the Deputy flue, and then through the hole on the partition into the main flue, which can ensure that each household is separated from the fumes. 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, pay attention to the details of the construction

，選擇抽油煙機(jī)安裝的位置十分重要。管道越短越好。一些業(yè)主會(huì)為了美觀，把管道拉得比較長(zhǎng)，這樣一來(lái)，關(guān)掉油煙機(jī)后，管道里還會(huì)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(kāi)口方向不是隨意可以改的，一定要打在副煙道里面。

First of all, select the location of the installation is very important. The shorter the pipeline 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 opening direction is not optional can be changed, must play in the auxiliary flue.

三、窗戶排煙注意

Three, window smoke safety

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(kāi)孔排煙，這樣做是可以的，但有幾點(diǎn)需要注意。

Some owners in order to avoid the problem of smoke, to abandon the original flue, directly on the window hole exhaust, so it is possible, but there are a few points need to pay attention to.

在窗戶或墻面開(kāi)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(kāi)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。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。

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 is best to put the pipe out of the pipe after the nest, so as to avoid rain when the rain water into the pipe, and the windshield outside.

四、止逆閥門勤更換

Four, check valve often change

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(kāi)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. Under normal circumstances, the effect of the smoke damper is not very obvious, and the installation of the valve can be installed in the flue valve to protect the hood, so that the smoke in the flue will not be inside the pipeline and fume extractor. However, the installation of check valve to be cleaned regularly, otherwise it will make the check valve is open, the effect is lost, and the best way to replace the flue valve about two years.
