現(xiàn)如今，廚房排煙管道在市場上十分受歡迎，隨著經(jīng)濟(jì)的不斷發(fā)展，越來越多的消費(fèi)者選擇安裝該管道，那大家知道安裝其時需要了解哪些點(diǎn)嗎？下面，跟隨通風(fēng)管道安裝廠家一起去下文了解一下吧，希望能幫到大家。

Nowadays, kitchen exhaust pipe is very popular in the market. With the continuous development of economy, more and more consumers choose to install the pipe. Do you know what you need to know at the time of installation? Now, follow the ventilation pipe installation manufacturers to understand it, hope to help you.

1、注意施工細(xì)節(jié)

1. Pay attention to construction details

選擇吸油煙機(jī)的安裝位置非常重要，管子越短越好。有些業(yè)主為了美觀，會把煙斗拉得更長一些，這樣在油煙機(jī)關(guān)掉后，很多油煙會聚集在煙斗里，無法排出，然后再倒回房間。另外，為了不損壞原主輔煙道，其開啟方向不能隨意改變，需要在輔助煙道中沖孔。

It is very important to choose the installation position of range hood. The shorter the pipe, the better. For the sake of beauty, some owners will pull the pipe longer. In this way, after the lampblack mechanism falls off, a lot of lampblack will gather in the pipe and cannot be discharged, and then it will be poured back into the room. In addition, in order not to damage the original main and auxiliary flue, its opening direction can not be changed at will, so it is necessary to punch holes in the auxiliary flue.

2、經(jīng)常更換止回閥

2. Replace the check valve frequently

如果輔助煙道已被拆除，或有必要更好地防止反煙的影響，則使用煙道止回閥。

If the auxiliary flue has been removed, or it is necessary to better prevent the influence of back smoke, the flue check valve shall be used.

一般來說，排油煙機(jī)的止回閥作用不是很明顯，排煙管道安裝廠家建議在煙道內(nèi)安裝止回閥可以保護(hù)排油煙機(jī)，使煙道內(nèi)的煙不會倒回管道和排油煙機(jī)；但止回閥安裝后應(yīng)定期清洗，否則止回閥將開啟失效，煙道止回閥每兩年左右更換一次。

Generally speaking, the function of the check valve of the range hood is not very obvious. The installation manufacturer of the smoke exhaust pipe suggests that the check valve should be installed in the flue to protect the range hood, so that the smoke in the flue will not return to the pipe and the range hood. However, the check valve should be cleaned regularly after installation, otherwise the check valve will fail to open, and the flue check valve should be replaced every two years or so.

3、保留輔助煙道

3. Reserve auxiliary flue

每個廚房都有一個煙道，煙道也有主要和輔助部分。通風(fēng)管道加工廠家表示主煙道貫穿整個建筑，輔助煙道相對獨(dú)立。

Each kitchen has a flue, which also has main and auxiliary parts. The ventilation duct manufacturer said that the main flue runs through the whole building, and the auxiliary flue is relatively independent.

一般情況下，室內(nèi)的油煙進(jìn)入輔助煙道，再通過隔板上的孔進(jìn)入主煙道，以保證每戶室內(nèi)的油煙被隔離。如果二次煙道直接與主煙道相連，會因壓力低而產(chǎn)生倒煙或煙串現(xiàn)象。

Generally, the indoor oil fume enters into the auxiliary flue, and then enters into the main flue through the hole on the partition plate, so as to ensure that the indoor oil fume of each household is isolated. If the secondary flue is directly connected with the main flue, it will produce inverted smoke or smoke string due to low pressure.

4、 窗戶排煙

4. Smoke exhaust from windows

一些業(yè)主為了避免出現(xiàn)冒煙問題，放棄原來的煙道，直接在窗戶上開孔進(jìn)行排煙，這是可以的，但有幾點(diǎn)需要注意。

In order to avoid the smoke problem, some owners give up the original flue and directly open holes on the windows for smoke exhaust. This is OK, but there are several points to pay attention to.

要在窗戶或墻上開個洞前需要征得物業(yè)同意；其次，注意問題。一般來說，排煙管的末端是由金屬制成的。如果開口太小，金屬傳熱可能會使玻璃破裂，傷及行人。而且，煙管通向窗戶，迎面吹來的北風(fēng)會導(dǎo)致油煙倒灌。盡量是把管子伸出來，然后把它套在下面，以防下雨時雨水流入管子，把擋風(fēng)玻璃放在外面。

Before opening a hole in the window or wall, you need to obtain the consent of the property; secondly, pay attention to safety. Generally speaking, the end of the exhaust pipe is made of metal. If the opening is too small, the heat transfer of metal may break the glass and injure pedestrians. Moreover, the smoke pipe leads to the window, and the northerly wind from the front will cause the oil smoke to pour back. Try to stick the pipe out, then put it under to prevent the rain from flowing into the pipe when it rains, and leave the windshield outside.
