How to judge whether a house is a single flue or a double flue?

Many owners don't know enough about decoration knowledge, which will have an irreversible impact on their later life. So in the process of decoration, they must know more about some knowledge points, such as kitchen flue. If the design is not good, they need to put up with the smell of cooking, even if the range hood is on all day. So, how to judge whether the house is a single flue or a double flue? What are the classifications of kitchen flue? Let's have a brief look with Bian Xiao.

First, how to judge whether the house is a single flue or a double flue?

If the owner buys a rough house, he can see the flue directly when he looks at the house. Even if there are two holes, a single hole is generally a single flue. In general, the main flue is the gathering place of oil fume connecting the whole residential kitchen, and the pipes are vertically connected, while the auxiliary flue is designed horizontally to prevent oil fume from escaping everywhere. It is suggested that owners who don't understand ask developers directly.

Second, what are the classification of kitchen flue?

1, single flue exhaust pipe

This is an early popular flue design method. The structure is too simple, and the import and export are not handled accordingly. Therefore, it is easy for a house with this structure to run around, and even using a range hood will not help.

2. Exhaust passage of primary and secondary flue

This kind of flue design is what we often call double flue, and it is also a common flue structure now. Adding a partition to the traditional single flue can turn it into a primary flue and a secondary flue, which can effectively prevent the oil fume from leaking out.

3. Porous variable pressure exhaust pipe

This structure is a transformation of the primary and secondary flue, which not only increases the cross-sectional area of the main flue, but also makes appropriate changes to the cross-sectional shape, so that the oil fume keeps flowing upwards, with remarkable effect, but also high cost.

4. Check valve exhaust passage

This is a reconstruction based on a single flue. Although there is only one flue, each entrance will be designed with a check valve to prevent oil smoke from escaping. Compared with porous variable pressure exhaust duct, it can reduce the floor space, but the construction is very troublesome.
