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. 现在把油烟通风管道、规范的规划必须符合国家标准,必须有产品合格证,质量和检验证书,如果通风管不符合国家规范规定的计划,所以在使用的过程中,简单的可以攻击安全事故,形成不必要的伤害,所以,在选择通风管道尺寸和规格,还要求对通风管道有一定的基础知识。通风管道尺寸为2000*450左右，为大型通风管道。

　　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. 一般情况下，在购买通风管道时，规格书中有尺寸和要求等信息。此外,如果不相信,自己计算,风速,风管道被风管道横截面积乘以3600,那些计算通风管道尺寸,风的风速管其中第二更好不超过15米,更好8-12m第二。安装通风管道时，通风管道两端应灵活滚动，不得有明显划痕。

　　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.实际上，通风管道有很多种，包括玻璃纤维通风管道、钢板通风管道、组合数据通风管道、不锈钢通风管道、塑料通风管道、单面彩钢通风管道等。根据其用途来区分，有工业排风风道、空调通风风道、燃气通风风道、净化系统通风风道等，可适用于不同的场所;假如根据通风管道的外形来分，又将螺旋形、圆形、长方形等，而每段通风管道的尺寸会不同。

　　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，我们大致了解了通风管道的大小、分类和形状。其次，还有另一种分类，这是更重要的。安装时，吊架开口与通风管道插管口的距离不应小于20cm。法兰管螺栓间距应在100mm-150mm之间，法兰管应独立绝缘，材料应与通风管道安装材料一致。

　　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. 假如要选择安装浴坝通风管道，其规范尺寸需要300*300mm，或300*600，其直径约100-150，这个通风管道尺寸还是要根据家中的面积来选购大小合适的通风管道。而根据国家规范，通风管道的规格在40cm以下，其吊顶的距离不得大于4m，若通风管道则在40cm以上，其吊顶的距离不得大于3m。根据通风管道安装方式的不同，安装规格也不同，可以是直线安装，也可以是平行安装。

　　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.

　　结论:综上所述，通风管道的尺寸及安装规范主要有以上五点。通风管道安装本可以使空气得以顺畅流通，所以在安装上也就更注重了，否则也不会有什么效果!

　　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!
