　　When it comes to the ventilation pipe, everyone will think that it is usually installed in the living room to install the air circulation. In fact, there is nothing wrong with it. The installation of the main ventilation pipe usually has professional technology, which is not clear to us, but there is also a friend who is interested in the size and installation specifications of the ventilation pipe, so today's editor will give you the size and installation specifications of the ventilation pipe.

　　1. 現(xiàn)在把油煙通風(fēng)管道、規(guī)范的規(guī)劃必須符合國家標(biāo)準(zhǔn),必須有產(chǎn)品合格證,質(zhì)量和檢驗證書,如果通風(fēng)管不符合國家規(guī)范規(guī)定的計劃,所以在使用的過程中,簡單的可以攻擊安全事故,形成不必要的傷害,所以,在選擇通風(fēng)管道尺寸和規(guī)格,還要求對通風(fēng)管道有一定的基礎(chǔ)知識。通風(fēng)管道尺寸為2000*450左右，為大型通風(fēng)管道。

　　1. At present, the planning of oil smoke ventilation pipes and specifications must conform to national standards, and must have product qualification certificate, quality and inspection certificate. If the ventilation pipes do not conform to the plan specified by national standards, they can attack safety accidents and form unnecessary injuries in the process of use. Therefore, in selecting the size and specifications of the ventilation pipes, it is also required to have certain basic knowledge of the ventilation pipes Knowledge. The size of ventilation pipe is about 2000 * 450, which is a large ventilation pipe.

　　2. 一般情況下，在購買通風(fēng)管道時，規(guī)格書中有尺寸和要求等信息。此外,如果不相信,自己計算,風(fēng)速,風(fēng)管道被風(fēng)管道橫截面積乘以3600,那些計算通風(fēng)管道尺寸,風(fēng)的風(fēng)速管其中第二更好不超過15米,更好8-12m第二。安裝通風(fēng)管道時，通風(fēng)管道兩端應(yīng)靈活滾動，不得有明顯劃痕。

　　2. In general, when purchasing the ventilation pipe, there are dimensions, requirements and other information in the specification. In addition, if you don't believe it, you can calculate the wind speed by multiplying the cross-sectional area of the wind pipe by 3600. For those calculating the size of the ventilation pipe, the second best is no more than 15m, and the second best is 8-12m. When installing the ventilation pipe, both ends of the ventilation pipe shall roll flexibly without obvious scratches.

　　3.實際上，通風(fēng)管道有很多種，包括玻璃纖維通風(fēng)管道、鋼板通風(fēng)管道、組合數(shù)據(jù)通風(fēng)管道、不銹鋼通風(fēng)管道、塑料通風(fēng)管道、單面彩鋼通風(fēng)管道等。根據(jù)其用途來區(qū)分，有工業(yè)排風(fēng)風(fēng)道、空調(diào)通風(fēng)風(fēng)道、燃?xì)馔L(fēng)風(fēng)道、凈化系統(tǒng)通風(fēng)風(fēng)道等，可適用于不同的場所;假如根據(jù)通風(fēng)管道的外形來分，又將螺旋形、圓形、長方形等，而每段通風(fēng)管道的尺寸會不同。

　　3. In fact, there are many kinds of ventilation pipes, including fiberglass ventilation pipes, steel plate ventilation pipes, combined data ventilation pipes, stainless steel ventilation pipes, plastic ventilation pipes, single-sided color steel ventilation pipes, etc. According to its use to distinguish, there are industrial exhaust air duct, air conditioning ventilation air duct, gas ventilation air duct, purification system ventilation air duct, etc., which can be used in different places; if according to the shape of the ventilation pipe, it will be spiral, circular, rectangular, etc., and the size of each section of ventilation pipe will be different.

　　4. 在前面，我們大致了解了通風(fēng)管道的大小、分類和形狀。其次，還有另一種分類，這是更重要的。安裝時，吊架開口與通風(fēng)管道插管口的距離不應(yīng)小于20cm。法蘭管螺栓間距應(yīng)在100mm-150mm之間，法蘭管應(yīng)獨立絕緣，材料應(yīng)與通風(fēng)管道安裝材料一致。

　　4. In the front, we have a general understanding of the size, classification and shape of ventilation pipes. Secondly, there is another classification, which is the most important. During installation, the distance between hanger opening and ventilation pipe intubation opening shall not be less than 20cm. The bolt spacing of flange pipe shall be between 100 mm and 150 mm, the flange pipe shall be isolated independently, and the material shall be the same as the installation material of ventilation pipe.

　　5. 假如要選擇安裝浴壩通風(fēng)管道，其規(guī)范尺寸需要300*300mm，或300*600，其直徑約100-150，這個通風(fēng)管道尺寸還是要根據(jù)家中的面積來選購大小合適的通風(fēng)管道。而根據(jù)國家規(guī)范，通風(fēng)管道的規(guī)格在40cm以下，其吊頂?shù)木嚯x不得大于4m，若通風(fēng)管道則在40cm以上，其吊頂?shù)木嚯x不得大于3m。根據(jù)通風(fēng)管道安裝方式的不同，安裝規(guī)格也不同，可以是直線安裝，也可以是平行安裝。

　　5. If you want to install the ventilation pipe of the bath dam, its standard size needs 300 * 300 mm, or 300 * 600, and its diameter is about 100-150. The size of the ventilation pipe should be selected according to the area of the home. According to the national code, the specification of the ventilation pipe is below 40cm, and the distance of the ceiling shall not be greater than 4m. If the ventilation pipe is above 40cm, the distance of the ceiling shall not be greater than 3m. According to the different installation methods of ventilation pipes, the installation specifications are also different, which can be straight-line installation or parallel installation.

　　結(jié)論:綜上所述，通風(fēng)管道的尺寸及安裝規(guī)范主要有以上五點。通風(fēng)管道安裝本可以使空氣得以順暢流通，所以在安裝上也就更注重了，否則也不會有什么效果!

　　Conclusion: To sum up, the size and installation specifications of ventilation pipe mainly have the above five points. The installation of ventilation pipe can make the air flow smoothly, so more attention should be paid to the installation, otherwise it will not have any effect!
