通风阻燃风管怎么安装,通风阻燃风管连接方式有哪些

How to install the ventilation and flame-retardant duct? What are the connection ways of the ventilation and flame-retardant duct

风管是用于空气输送和分布的管道系统，通风阻燃风管是由PP材料制作的通风管，与其他材质风管相比，它具有耐磨损、不结垢，流动阻力小，耐腐蚀等***性，而且抗冻裂，隔音效果***，是目前使用非常广泛的一种管材。由于通风阻燃风管所具有的这些***点，其也被用于废气环保设备中，降低有害气体的浓度，使空气流通。由于通风阻燃风管都是一节一节的，如果连接不当会出现泄漏，起不到应有的效果，因此要严格按照步骤一步步安装。

The air duct is a pipe system used for air transmission and distribution. The flame-retardant air duct is made of PP material. Compared with other materials, it has the characteristics of wear-resistant, non scaling, small flow resistance, corrosion resistance, etc., and it has good frost crack resistance and sound insulation effect. It is a kind of pipe widely used at present. Due to these characteristics of the ventilation and flame-retardant duct, it is also used in the waste gas environmental protection equipment to reduce the concentration of harmful gases and make the air circulate. As the ventilation and flame-retardant air ducts are all section by section, if not properly connected, there will be leakage, which will not play its due effect, so it is necessary to strictly follow the step-by-step installation.

下面通风阻燃风管厂家为***家讲讲安装工序：

The following ventilation and flame-retardant air duct manufacturers will introduce the installation process for you:

1、通风阻燃风管运到施工现场后，对照图纸核对通风阻燃风管风口规格尺寸，按系统分开堆放并做***标识，以免安装时弄错。

2、安装通风阻燃风管风口前要仔细对风口进行检查，看风口有无损坏、表面有无划痕等缺陷。凡是有调节、旋转部分的风口要检查活动件是否灵活，叶片是否平直，与边框有无摩擦。对有过滤网的可开启式风口，要检查过滤网有无损坏。

2. Before installing the vent of ventilation flame-retardant air duct, check the vent carefully to see whether it is damaged, whether the surface is scratched and other defects. All air outlets with adjustment and rotation parts shall be checked to see whether the movable parts are flexible, whether the blades are straight, and whether there is friction with the frame. For the openable air outlet with filter screen, check whether the filter screen is damaged.

3、在安装风口时，注意通风阻燃风管暗装时，吸***安装的散流器与屋***平齐，风口安装要确保牢固可靠，尤其弯头部位一定要做***连接措施。

3. When installing the air vent, pay attention to the concealed installation of the ventilation flame-retardant air duct, the diffuser installed on the ceiling shall be flush with the roof, and the installation of the air vent shall be firm and reliable, especially the connection measures shall be taken at the elbow.

4、通风阻燃风管安装完后可以试运行，待其通风无阻后才可正式使用。

4. The ventilation and flame-retardant air duct can be put into trial operation after installation, and can be formally used only after the ventilation is unimpeded.

风管的连接方式两平且应笔直，不得错位和变形。武汉螺旋风管平时的连接方式有几种?

The air duct shall be connected in two flat and straight ways without dislocation and deformation. How many ways do Wuhan spiral air ducts connect at ordinary times?

一、插入类型连接

I. insert type connection

卡口式风道与矩形风道连接，将不同形式的卡口插入风道两端。

The bayonet type air duct is connected with the rectangular air duct, and different bayonets are inserted into both ends of the air duct.

二、通风阻燃风管连接

II. Connection of ventilation and flame retardant air duct

每一管段的两端均卷成带箍连接的鼓杆，一端缩为小开口。安装时，根据气流方向将小口插入***口内。在外面，将两个管端的鼓杆紧固并与螺栓连接，螺栓固定并紧固在耳环上。

The two ends of each pipe section are rolled into drum rods connected with hoops, and one end is shrunk into a small opening. During installation, insert the small port into the large port according to the air flow direction. On the outside, fasten the drum rods of the two pipe ends and connect them with bolts, which are fixed on the earrings.

软管连接。

Hose connections.

软管连接主要用于螺旋气管与各部件(如扩压器静压箱侧出风口等)的连接。

The hose connection is mainly used for the connection between the spiral gas pipe and various components (such as the air outlet at the static pressure box side of the diffuser, etc.).

四、通风阻燃风管插入连接

IV. insertion and connection of ventilation and flame-retardant air duct

塞式连接主要用于矩形或圆形风管连接。***先制作连接管，然后将连接管插入两侧的风管中。然后，用自攻螺丝或拉柳钉将其紧固。通风阻燃风管经济，在相同直径下，通风阻燃风管加工板厚度可减少10% - 15%。它降低了成本，在吊装时的效率***约是矩形通风阻燃风管的两倍。在相同板厚和管径下，通风阻燃风管的强度较高。在相同截面上，螺旋风管结构张力更合理，刚性更***，因此能******降低噪音和振动

Plug connection is mainly used for rectangular or circular duct connection. Make the connecting pipe first, and then insert it into the duct on both sides. Then, fasten it with self tapping screw or pulling willow nail. Under the same diameter, the thickness of the processing plate of the ventilation and flame-retardant duct can be reduced by 10% - 15%. It reduces the cost, and the efficiency of hoisting is about twice that of Rectangular Ventilation flame-retardant duct. Under the same thickness and pipe diameter, the intensity of ventilation flame-retardant duct is higher. In the same section, the spiral duct structure has more reasonable tension and better rigidity, so it can greatly reduce noise and vibration
