Everyone knows about the flue. The flue is the pipe for exhausting smoke. But there are many kinds of flue. In fact, many people don’t understand the flue. If you don’t know what the flue is, then pick it up. Let's take a look at the small series of the decoration home network to tell you about the characteristics of the flue equipment and what installation steps. I hope that you can understand the flue through the introduction of Xiaobian.
First, the characteristics of the flue equipment
1. Emissions of flue gas on each floor of the flue: The overall flow balance system of the flue enables the upper airflow to drive the lower airflow upwards, which promotes the smooth exhaust of the lower floor and overcomes the phenomenon that the exhaust volume is attenuated layer by layer from top to bottom.
2, the flue prevention effect is good: the flue not only prevents rain and snow from instilling the exhaust passage, but also can use the wind pressure to generate smoke extraction effect and promote smoke emission.
3, flue anti-stringer odor effect is good: the flue is tested, can effectively prevent the phenomenon of cross-smoke odor, and avoid cross-contamination between households.
4. Convenient selection of flue design: the position and direction of the flue exhaust port are not limited, easy to design and select, and easy to install.
5. The flue exhaust is smooth and fast: the flue system has low airflow resistance and high airflow speed.
6, the flue area is small: the flue section is small, occupying a small space, saving space.
7. Flue saves raw materials and energy consumption: flue raw materials and energy consumption are low.
Second, the flue equipment installation steps
1. During the construction of the main structure, according to the position of the design drawings, the holes of the ventilation flue are reserved, and the size of the holes is 50~80 mm more than the outer dimensions of the components. The steel bars in the reserved holes should also be reserved at the same time.
2. Before installation, hang the vertical line from the top hole according to the size of the ventilation flue to ensure the verticality of the flue installation. When installing the first floor, first level the ground with 1:2 cement mortar. After the first section of the tube is filled with pure pulp, the C20 concrete of about 40 cm height is poured in the tube; after the final setting, the non-ventilating flue is installed.
3. First place the lower part of the connecting piece on the upper mouth of the lower flue partition, and the four sides should also be sealed by the slurry. Ventilation flue should be treated as a layered support. Construction practice: After the upper and lower pipes are aligned with the grout, the interface of the upper and lower ventilation flue is generally located at the floor. Therefore, at the root of the pipe, the welded steel slab 12 is added to the steel plate and the hole is reserved for welding, and is supported on the base of the slab.
4. The upper and lower joints of the ventilation flue are coated with polymer cement slurry (108 glue: cement = 6:1); the joint between the ventilation flue and the stairwell should be pre-hammered, cleaned and the mold is used, with C20 Fine stone micro-expansion ç ¼ fill. The concrete surface at the joint should be about 3 cm lower than the floor. After filling the concrete, water is stored on the surface of the concrete.
Now every family is a soot. The range hood in our home is a flue. Otherwise, where does the smoke come from? What are the features and installation steps of the flue equipment? I think you can pass the above series. The introduction is also familiar with these issues, then if you still want to know more about decoration information, please continue to pay attention to the decoration home Internet cafe.
