Are you familiar with the flue? Flue is a pipe for discharging flue gas, but there are many kinds of flue gas. In fact, many people don't know about smoke, and they don't know what smoke is for. Then let's introduce the characteristics and installation steps of flue gas equipment. I hope you can learn about the flue through Bian Xiao's introduction.

First, the characteristics of flue equipment

1. Balanced smoke exhaust at each floor of the flue: The overall flow balance system of the flue makes the upper airflow drive the lower airflow to flow upward, which promotes the smooth smoke exhaust at the lower floor and overcomes the phenomenon that the exhaust air volume decreases from top to bottom.

2. Flue has good backflow prevention effect: the flue not only prevents rain and snow from flowing back to the exhaust duct, but also can produce smoke exhaust effect with the help of wind pressure transformation to promote smoke exhaust.

3. The flue has a good smoke and odor prevention effect: after testing, the flue can effectively prevent smoke and odor and avoid cross-contamination among households.

4. Convenient design and selection of flue: the position and direction of flue outlet are not limited, so it is easy to design, select and install.

5. Flue exhaust is smooth and fast: the airflow resistance of the flue system is small and the airflow speed is high.

6. The flue covers a small area: the section of the flue is small, occupying a small space and saving space.

7. The invention saves raw materials and energy consumption: the raw materials and energy consumption of the invention are low.

Second, the flue equipment installation steps

1. When the main structure is constructed, ventilation flue holes shall be reserved according to the position of design drawings, and the hole size is 50~80mm larger than the peripheral size of components. The reinforcement in the reserved hole should also be reserved.

2, before installation, according to the size of the ventilation flue hanging vertical hole from the top, to ensure the verticality of flue installation. When installing the first layer, first level it with 1:2 cement mortar. After the first section of pipe joint is grouted, C20 concrete about 40cm high is poured in the pipe; After the final set of concrete, install ventilation flue.

3. First, put the lower mouth of the joint into the upper mouth of the lower flue partition, and seal its four sides with cement slurry. Ventilation flue should be supported by layers. Construction practice: After grouting the upper and lower pipes, the interface of the upper and lower ventilation flue is generally located at the floor, so the Ф12 steel bar is welded at the embedded steel plate at the root of the pipe and welded with the steel bar reserved in the hole, and supported on the floor foundation.

4. Coat the upper and lower joint surfaces of ventilation flue with polymer cement slurry (108 glue: cement = 6:1); The seam between ventilation flue and stairwell should be cut in advance, cleaned and closed, and filled with C20 fine stone micro-expansive concrete. The concrete surface at the joint should be about 3 cm lower than the floor. After concrete pouring, water is stored on the concrete surface for curing.

Now, every family has an oil fume duct. The range hood decorated in our house has a flue. Where else did the smoke come from? What are the characteristics and installation steps of flue equipment? Through the introduction of the above small series, I think you all understand these problems.
