在我們的家居生活或辦公場(chǎng)所中，室內(nèi)通風(fēng)很重要。如果通風(fēng)不好，長期在里面的人就會(huì)感到缺氧、難受，進(jìn)而影響正常的工作與生活，所以通風(fēng)管道的安裝是很重要的。下面小編就來為大家介紹下通風(fēng)管道的安裝問題及注意事項(xiàng)，希望能對(duì)您有所幫助。

Indoor ventilation is very important in our home life or office. If the ventilation is not good, people who have been inside for a long time will feel anoxic and uncomfortable, which will affect their normal work and life. Therefore, the installation of ventilation pipes is very important. The following small series will introduce the installation problems and precautions of ventilation duct, hoping to help you.

通風(fēng)管道要求—抽油煙的通風(fēng)管道安裝

Ventilation duct requirements - Installation of ventilation ducts for oil fume extraction

如果是要安裝抽油煙機(jī)的通風(fēng)管道，在進(jìn)行設(shè)計(jì)的時(shí)候，要以國家的標(biāo)準(zhǔn)為準(zhǔn)，并要定要有生產(chǎn)廠家的合格證書以及檢驗(yàn)證書，如果通風(fēng)管道沒有達(dá)到國家規(guī)定的設(shè)計(jì)標(biāo)準(zhǔn)，那么在使用的過程中，很容易就會(huì)發(fā)生安全事故，造成不必要的危害。通風(fēng)管尺寸在2000*450左右，是比較大的通風(fēng)管道了。

If the ventilation duct of the range hood is to be installed, the national standard shall prevail in the design, and the manufacturer's certificate of conformity and inspection certificate shall be provided. If the ventilation duct does not meet the national design standard, it is easy to have safety accidents and unnecessary hazards in the process of use. The size of the ventilation pipe is about 2000 * 450, which is a relatively large ventilation pipe.

通風(fēng)管道要求—浴霸通風(fēng)管道安裝

Ventilation duct requirements - Yuba ventilation duct installation

如果要選擇安裝浴霸通風(fēng)管道的話，其規(guī)格尺寸需要300*300mm，或者300*600，其直徑大概是在100到150之間，這個(gè)通風(fēng)管道尺寸還是要根據(jù)家里的面積來選購一款大小合適的通風(fēng)管道。而根據(jù)國家標(biāo)準(zhǔn)，通風(fēng)管道的規(guī)格在40厘米一下的，其吊架的距離不得大于4米，如果通風(fēng)管道規(guī)格是在40厘米以上的，其吊架的距離不得大于3米。

If you want to choose to install Yuba ventilation pipe, its specification and size need to be 300 * 300mm, or 300 * 600, and its diameter is about 100 to 150. This ventilation pipe size still needs to choose a ventilation pipe of appropriate size according to the area of the home. According to the national standard, if the specification of the ventilation pipe is less than 40cm, the distance between the hangers shall not be greater than 4m. If the specification of the ventilation pipe is more than 40cm, the distance between the hangers shall not be greater than 3m.

通風(fēng)管道要求—通風(fēng)管道尺寸要測(cè)量好

Ventilation duct requirements - the size of ventilation duct shall be measured

通風(fēng)管道尺寸要計(jì)算好，其方法就是風(fēng)管的橫截面積乘以風(fēng)管的風(fēng)速再乘以3600，計(jì)算出來的結(jié)構(gòu)就是通風(fēng)管道的尺寸了，其中風(fēng)管的風(fēng)速更好不要超過15米每秒，更好的風(fēng)速就是8到12米每秒為好。在安裝通風(fēng)管道的時(shí)候，風(fēng)管的兩端應(yīng)該轉(zhuǎn)動(dòng)靈活，不得有明顯的劃痕。

The size of the ventilation duct should be calculated well by multiplying the cross-sectional area of the air duct by the wind speed of the air duct and then multiplying by 3600. The calculated structure is the size of the ventilation duct. The wind speed of the air duct should not exceed 15 meters per second, and the best wind speed is 8 to 12 meters per second. When installing the ventilation duct, both ends of the air duct shall rotate flexibly without obvious scratches.

通風(fēng)管道注意—要注意通風(fēng)管道的材料

Attention to ventilation duct - pay attention to the material of ventilation duct

通風(fēng)管道的材料比較多，比如鋼板風(fēng)管、玻璃鋼通風(fēng)管道、復(fù)合材料通風(fēng)管道、塑料通風(fēng)管道、不銹鋼通風(fēng)管、單面彩鋼通風(fēng)管等等。而從用途上來看，有可以分為工業(yè)排風(fēng)通風(fēng)管道、凈化系統(tǒng)通風(fēng)管道、空調(diào)通風(fēng)管道、瓦斯通風(fēng)管道等等。形狀不同，通風(fēng)管道類型也不一樣。

There are many materials for ventilation pipes, such as steel plate ventilation pipe, FRP ventilation pipe, composite ventilation pipe, plastic ventilation pipe, stainless steel ventilation pipe, single-sided color steel ventilation pipe, etc. In terms of use, it can be divided into industrial exhaust ventilation duct, purification system ventilation duct, air conditioning ventilation duct, gas ventilation duct and so on. The type of ventilation duct varies with the shape.
