What are the common causes of public flue odor crossing?

Public flue fumes smell.

One is the weather, such as low air pressure.

or strong winds, resulting in oil smoke being pressed and unable to be discharged;

The second is the structural reason, the general kitchen flue is divided into the main flue and the auxiliary flue, and the oil smoke of each household is discharged into its own independent auxiliary flue first, and then enters the main flue, which is discharged from the exhaust port of the roof flue. The flue in some communities is an old-fashioned flue design (there is no distinction between main and secondary flues), which is prone to cross-smelling;

The third is man-made reasons, the real estate developer blocked the public flue during construction or the upstairs residents during renovation. Therefore, it is best for every owner to check whether the public flue is smooth before renovation to see if there is any construction waste.

Plugging in it. It should also be reminded that since the flue is very thin, it is easy to crack, and the oil smoke is also very easy to seep out of the crack. Therefore, when decorating a new house, the flue must be re-pulled with barbed wire, then painted, and finally tiled, so that the probability of the flue cracking is relatively small.

Solution: 1. A one-way valve should be installed at the opening, that is, it should be opened when it is discharged to the outside and closed when it is not exhausted, so as to prevent other people's exhaust from filling your home. This is the installation of a range hood.

a basic procedure and practice.

2. If it is because of the check valve of the public flue.

Caused by poor effect, the best way to solve the smell of the range hood is to install a check valve, but there are two check valves, one is the range hood itself, which is installed at the air outlet of the range hood and the other is installed at the outlet of the public flue, which needs to be purchased by yourself.

1. The fumes generated by cooking rice and stir-frying vegetables at home.

2. The fumes of other people's houses who share the flue. If you know the origin of the fume, you will also know how to deal with it.

But when the owner decorates the house, the exhaust holes of the range hood are basically opened on the top of the ceiling, one is beautiful, and the other is clean and clean, but the flue aperture reserved by the developer is usually relatively low, in order to install it on the ceiling, the usual method is to seal the original.

On the top of the opening from scratch, some developers wear a plastic flue check valve, usually in the decoration workers are smashed during construction, and some in the range hood equipment, the usual practice is to put the range hood exhaust pipe directly into the public flue, directly sealed with glue.

There are two factors to this.

1. The check valve on the range hood is a double-bladed plastic check valve, which can be seen when the range hood is turned on, and its tightness does not need to be said, it can be understood at a glance.

2. The flue exhaust hole opened from the beginning of the decoration, without the guidance of the guide pipe, the aftertaste strength is much larger, the most important thing is that the plastic valve on the flue of the equipment is a traditional valve, and its tightness is also visible.

Install flue check valves in the kitchen. Prevents the air flow from going backwards and forces the flue gas to move in one direction towards the flue.

Principle: First, it is convenient for the emission of indoor fumes.

The second is to prevent outdoor fumes from backing up and returning to the kitchen, polluting the indoor environment, and it is necessary to ensure that the check valve is installed firmly and has no gap with the wall.

The smoke check valve is fundamentally different from the oil exhaust structure of the traditional range hood. The traditional range hood adopts the in-line oil exhaust method, which inevitably produces the phenomenon of oil smoke return. When the range hood is working, its wind power will lift the smoke cap, and its own oil smoke will be discharged from the side of the smoke cap;

When the range hood stops working, the hood will automatically fall down, and the flue mouth is tightly sealed. In this way, the fumes (smells) in the flue will never return.

A one-way valve should be installed at the opening, that is, it is opened when it is exhausted outward, and closed when it is not exhausted, so as to prevent other people's exhaust from pouring into your home. This is a basic procedure and practice when installing a range hood.

There are two ways, one is to restore the original flue upstairs, which is the best. It's about making a hole and going out, but that will affect the rest of the people upstairs because the smoke will drift to someone else's house. It is advisable to join others to request that the flue be restored.

You can buy a good range hood, it's best if you change it to a separate one, my neighbor did it, and I replaced it with a better range hood.

There are generally three reasons for the smell of public flues, namely weather reasons, structural reasons, and man-made reasons. 1. Weather reasons: such as low air pressure or strong winds, resulting in oil smoke being pressed and unable to be discharged.

2. Structural reasons: The flue in some communities is an old-fashioned flue design (there is no distinction between main and secondary flues), which is prone to cross-smelling. 3. Human causes:

The developer blocked the public flue during construction or during renovation by the upstairs occupants. <

<>1. It is recommended to install a flue check valve at the flue hole when the smoke pipe is pre-embedded, so as to prevent the retrograde flow of the spring dismantling and force the flue gas to move in one direction to the flue, which can effectively prevent the smoke from pouring into the smoke and smelling in the flue.

2. The flue check valve is a safety guard in the family, which can effectively prevent the toxic exhaust gas and oil smoke discharged from other people's homes in the public flue of jujube picking into their own homes. At the same time, it can also prevent mosquitoes, moths, flies and other flying insects, as well as geckos and other reptiles from entering the home, and most importantly, it can ensure that the air in your home is hygienic and safe.
