通风管道主要应用在工业及建筑工程中，应用领域主要涉及:电子工业无尘厂房净化系统，医药食品无菌车间净化系统，酒店宾馆、医院、工厂及写字楼的空调系统，工业污染控制用除尘、排烟、吸油等排风管、工业环境或岗位舒适用送风管、煤矿抽放瓦斯用抽放瓦斯系统、煤矿矿井环境控制用送回风系统。
The ventilation pipe is mainly used in industrial and construction projects, mainly related to application: purification system of electronic industry clean workshop, purifying system of medicine and food aseptic workshop, hotels, hospitals, shopping malls and office buildings factory of central air-conditioning system, with the addition of dust, smoke and fume exhaust pipe, etc. industrial environment comfortable by feeding or post the wind pipe, coal mine gas drainage in coal mine gas drainage system, environmental control system of industrial pollution control air supply.
风管及部件的安装
Installation of wind pipe and parts
风管及配件可拆卸的接口及调节阀门不得装设在墙内或楼板内。风管及配件安装前应内外杂物及污物并保持清洁。
The detachable interface and regulating valve of the wind pipe and accessories shall not be installed in the wall or in the floor. The internal and external impurities and dirt should be cleaned and kept clean before the installation of the wind pipe and accessories.
靠墙或靠柱安装的水平、垂直风管宜采用悬臂支架或斜撑支架。不靠墙、柱安装的水平风管宜用托底吊架，垂直风管应采用抱箍支架，风管b＞800mm应加双螺帽。并在转角处、顶端、末端设置防晃支架，支架不得设置在风口、阀门、检查孔及自控机构处。吊架不宜直接固定在法兰片上。
A horizontal and vertical wind pipe installed on a wall or a column should be supported by a cantilever bracket or a bracing support. Do not rely on the wall and column level wind pipe installed to use underpinning hanger, vertical wind pipe should be used in hoop bracket, duct b > 800mm should add double nut. At the corner, the top and the end, the anti - sway bracket is set up. The bracket shall not be set at the air vent, valve, check hole and automatic control mechanism. The hanger should not be fixed directly on the flange.
矩形风管抱箍支架应紧贴风管。如保温风管，应留有保温厚度浸沥青的木块风管吊架应平直、螺纹应光洁、吊杆拼接可采用焊接。长度不应少于吊杆直径的六倍，并应在两侧焊接。
The brackets of the hoop of the rectangular wind pipe should be tightly attached to the wind pipe. If the heat insulation pipe, the wood block hanger of the wood block should be kept straight, the thread should be smooth and the splice of the hanger can be welded. The length should not be less than six times the diameter of the hanger, and should be welded on both sides.
通风管道一般有:净化系统送回风管、空调通风管、工业送排风通风管、系统吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等。
Ventilation pipes usually include: purification system, return air pipe, central air conditioning ventilation pipe, industrial ventilation and ventilation pipe, environmental protection system suction and exhaust pipe, mine drainage gas pipe, mine coating cloth air duct and so on.
在通风系统中的风管是相互连接的一个整体，必然得遵循各支路阻力平衡规律，当风管系统的结构形式、管道尺寸一经确定，在一定的风机作用下，各段的风量是按阻力平衡规律自动分配的。在设计计算时未经阻力平衡计算，会导致系统实际风量分配与设计不符。
In the ventilation system of wind pipe is a whole connected, must follow the branch resistance balance law, when the structure, size of pipe duct system is confirmed, the fan under certain sections of the air volume according to the automatic distribution of resistance balance law. Without the calculation of resistance balance in the design and calculation, the actual air volume distribution and design of the system will not conform to the design.
