濟南廚房排煙進行裝修時要講究什么？實際上確實有多個事項要注意，都是對我們整個工程質量起到很大作用的，所以要重視起來，下面小編就來為您講講。

What should we pay attention to when decorating Jinan kitchen? In fact, there are many matters to be noted, which play a great role in the quality of our entire project, so we should pay attention to them. The following sections will tell you about them.

一、副煙道須留下

1、 The secondary flue must be left

通常，家中的油煙會進入副煙道中，經過一個緩存，接下來通過隔板上的孔洞進入主煙道，確保每家每戶的油煙分隔開，避免串煙。一些伙伴家出現了串煙的問題有可能是因為錯把排煙管與主煙道連在一起，或者為節約空間拆除副煙道。假如直接連上主煙道，因為向上的吸力很大，如果氣壓很低，就會將別家的油煙壓入咱們家中；因此，副煙道一定不能拆除。

Usually, the lampblack in the home will enter the secondary flue, pass through a buffer, and then enter the main flue through the holes on the partition board to ensure that the lampblack in each household is separated and avoid smoke. Some partners may have the problem of smoking because the smoke exhaust pipe is connected to the main flue by mistake, or the auxiliary flue is removed to save space. If it is directly connected to the main flue, because the upward suction is very large, if the air pressure is very low, the lampblack from other houses will be pressed into our house; Therefore, the auxiliary flue must not be removed.

二、施工就要“吹毛求疵”

2、 Construction should be "picky"

①油煙機安裝位置很重要。管道越短越好，一些朋友為了美觀或空間整潔度，將管道拉得很長，于是在關閉油煙機后，管道中會存留很多油煙無法排出，再倒回屋中。

① The installation position of the range hood is very important. The shorter the pipe, the better. Some friends pull the pipe very long for the sake of beauty or space cleanliness. Therefore, after the range hood is turned off, a lot of lampblack will remain in the pipe and cannot be discharged, and then it will be poured back into the house.

②開口方向不要隨意改動。為避免破壞原有主副煙道，開口的方向不要隨便改，須要打在副煙道中。但是煙道孔可擴張，不過不能損壞副煙道擋板。

② Do not change the opening direction at will. In order to avoid damaging the original main and auxiliary flue, the opening direction shall not be changed randomly, and it shall be set in the auxiliary flue. However, the flue hole can be expanded, but the auxiliary flue baffle cannot be damaged.

三、在窗戶排煙請注意

3、 Please pay attention to smoke in the window

有一部分朋友為了避免串煙，會將原本煙道放棄，而在窗戶上開孔排煙，這樣是沒問題的，不過有幾點要注意：

Some friends will give up the original flue and open holes in the windows to smoke in order to avoid smoke emission. This is OK, but there are several points to note:

1在窗戶或墻面開孔前，需要先經過物業允許。

1 Before opening windows or walls, property permission is required.

2通常排煙管尾端是金屬材質，假如開洞過小，金屬導熱后易讓玻璃炸裂，存在隱患，同時煙管通往窗外，風可能會對著吹使油煙倒灌，會增加油煙機的負荷，縮減它的使用壽命。

2 Usually, the tail end of the smoke exhaust pipe is made of metal. If the hole is too small, the glass will be easily cracked after the metal conducts heat, which is a potential safety hazard. At the same time, the smoke exhaust pipe will lead out of the window, and the wind may pour back the lampblack, which will increase the load of the range hood and shorten its service life.

解決方案：管道伸出后，將管道向下窩，這樣就可避免風吹，也能避免下雨，雨水流入管道中。

Solution: After the pipe is extended, the pipe shall be recessed downward, so as to avoid wind blowing and rain, which will flow into the pipe.

四、止逆閥門經常換

4、 Check valve is often replaced

假如你已將副煙道拆除，或是為防止倒煙問題安裝了煙道止逆閥，如果安裝了止逆閥一定要定期清洗，不然就會使其失去效用，另外需要兩年左右換一次。

If you have removed the auxiliary flue, or installed a flue check valve to prevent backflow, you must clean the check valve regularly if you have installed it, otherwise it will lose its effectiveness, and it will need to be replaced once every two years or so.

很多伙伴會疑惑，為何油煙機已有止逆閥還要另安裝呢？通常來說，油煙機的止逆閥效果微乎其微，在煙道安裝止逆閥，可有效保護油煙機，使煙道中的煙不會倒灌。更多事項就來我們網站http://www.pvcbox.cn咨詢吧。

Many partners will wonder why the check valve of the range hood has to be installed additionally? Generally speaking, the check valve of the range hood has very little effect. Installing a check valve in the flue can effectively protect the range hood from back filling of smoke in the flue. Come to our website for more information http://www.pvcbox.cn Consult.
