Ventilation duct is a product made for air circulation. Its characteristics and advantages are to achieve ventilation and enhance air circulation. Its material selection is generally made of profiles or plates. Here are the links and precautions:

1、插条式连接：主要用于矩形风管连接，它是将不同形式的插条插入风管两端，然后压实即可。

1. Insert connection: it is mainly used for rectangular air duct connection. It is to insert different forms of inserts into both ends of the air duct and then compact it.

2、插接式连接：主要用于矩形或圆形风管连接，首先制作连接管，然后插入两侧风管，后再用拉铆钉将其紧密固定。

2. Plug in connection: it is mainly used for the connection of rectangular or circular air ducts. First make the connecting pipes, then insert the air ducts on both sides, and then fix them tightly with pull rivets.

3、软管式连接：主要用于风管与部件的相连，安装的时候，软管两端套在连接的管外，然后用特别软卡把软管箍紧。

3. Hose connection: it is mainly used to connect the air duct and components. During installation, both ends of the hose are sleeved outside the connected pipe, and then the hose is clamped tightly with a special soft clamp.

4、抱箍式连接：主要用于钢板的圆通风管道和河南螺旋风管连接，先把每一管段的两端轧出鼓筋，并使其一端缩为小口，安装时按气流方向把小口插人大口，外面用钢制抱箍将两个端的鼓箍抱紧连接，后用螺栓穿在环中间固定拧紧。

4. Hoop connection: it is mainly used for the connection between the round air duct of steel plate and Henan spiral air duct. Firstly, roll out the drum reinforcement at both ends of each pipe section and shrink one end into a small opening. During installation, insert the small opening into the large opening according to the air flow direction. The drum hoops at both ends are tightly connected with steel hoops outside, and then threaded in the middle of the ring with bolts.

通风管道注意事项

Precautions for ventilation duct

1）对于比较复杂的民用建筑，在设计阶段，各工种（暖通、给水排水，供电照明与建筑）首先应协商好空间分隔，定出每种河南通风管道的标高范围。一般情况下不得越出给自己规定的界限。遇有个别管段要越界时应与其他工程协商。

1) For more complex civil buildings, in the design stage, various types of work (HVAC, water supply and drainage, power supply, lighting and Architecture) should first negotiate the space separation and determine the elevation range of each kind of Henan ventilation pipeline. In general, you should not go beyond the limits set for yourself. In case of crossing the boundary of an individual pipe section, it shall negotiate with other projects.

2）解决各种通风管道道相碰及协调的原则，一般为：“小管让大管，有压让无压”。例如，自来水管与通风管道相撞，则应当自来水管拐弯。冷、热水管与下水管相碰，则应改变冷、热水管道。

2) The principle to solve the collision and coordination of various ventilation ducts is generally as follows: "small pipe gives way to large pipe, pressure gives way to no pressure". For example, if the water pipe collides with the ventilation pipe, the water pipe should turn. If the cold and hot water pipes collide with the downpipe, the cold and hot water pipes shall be changed.

3）施工前应设备总管的工程师，将各工种的管线，单线画在一张平面图上。每种管道用一种彩色笔。在各交点处综合其标高，看是否有矛盾之处，及时发现，将问题解决在安装之前。

3) Before construction, the engineer of the equipment main pipe shall draw the pipeline and single line of each type of work on a plan. Use a color pen for each type of pipe. Synthesize the elevation at each intersection to see if there is any contradiction, find it in time and solve the problem before installation.

4）为了减少投资，节省空间，降低层高，有些敷设无坡度要求的管道，可以穿梁敷设（如自来水管道，消防喷洒干管等）。

4) In order to reduce investment, save space and reduce floor height, some pipelines without slope requirements can be laid through beams (such as tap water pipeline, fire spraying main pipe, etc.).
