What should I do if the smoke exhaust in the public flue of the kitchen at home is not smooth? Hello, pro 1: There is a gap between the smoke exhaust pipe of the range hood and the flue check valve or the connection of the hood machine, generally a check valve is installed between the flue mouth and the smoke exhaust pipe of the range hood, which can effectively prevent the backflow of oil smoke, but if there is a gap between the smoke exhaust pipe of the hood and the flue check valve or the connection with the smoke machine, the sealing is poor, the exhaust air volume of the smoke machine is large, and the flue air pressure is large, and it is easy to run smoke, which will also lead to poor smoke exhaust!

When installing, be sure to pay attention to the tightness of the connection at both ends of the smoke pipe! 2: flue opening error general kitchen has the main and auxiliary flues, under normal circumstances, the hole is opened in the auxiliary flue to connect the smoke exhaust pipe of the smoke machine, if the hole is opened in the main flue, it will lead to the problem of oil smoke backfilling, and the internal pressure of the flue will affect the smoke exhaust effect.

PS: The size of the liquid cry of the flue opening needs to be grasped, and the diameter of the general opening is 1 2cm larger than the diameter of the smoke pipe, so as to facilitate the installation of the smoke pipe in the later stage. 3：

The circulation section of the public flue leads to the general normal building standards, and the circulation section of the flue is: square centimeters, and in the face of the smoke exhaust needs of multi-family households, the smoke exhaust is not up to standard. In order to solve the problem of poor smoke exhaust in high-rise buildings, the public flue needs to adopt technologies and measures such as coupled sealing valves, anti-backfill hoods and transformers to avoid the problems of poor smoke exhaust and oil smoke backfilling.

If the kitchen at home has poor smoke exhaust in the public flue, you must quickly find someone to repair it. In fact, we often get this kind of thing in our daily life: when we get home, we can smell the food upstairs and downstairs, especially in the kitchen, but we must also pay attention to the problem when these smells arouse our taste buds, which indicates that there is a problem with the flue smoke exhaust.

It will affect our mood and body for a long time, and if we don't deal with it all the time, it will also affect our normal life, which isBecause some buildings have a very traditional design, they are all vertical single flues This kind of flue is very easy to cause the smell of oil smoke, which is why we smell the smell of food on other floors, if it is a family to cook, but at noon, the taste will be greater, and the developer in order to increase the area of the kitchen, the area of the flue is reduced without authorization, which leads to poor smoke exhaust.

One of the easiest ways to solve the problem is to do soFind a suitable position between your range hood and the public flue, and add a pneumatic flue check valve This seal is very good, and the check valve will only open under the action of power, if there is no power to close by itself, it is very convenient, and it can also isolate the odor of other floors of the flue.

At the same time, a stainless steel non-powered fan can also be installed , and then install a control line to synchronize the fan and range hood. However, there is one thing to pay attention to, that is, the newly added pneumatic flue check valve must be cleaned regularly, otherwise it will be full of oil smoke, and it will lose its effect at that time, and it will be replaced with a new one after about two years, so as to ensure the effect.

Check and clean up if the smoke exhaust is not smooth, it must be blocked somewhere, or the greasy is too heavy.

You should go to a repairman as soon as possible to repair or rearrange the pipes. Fix it quickly.

You can go to the property and ask him to call someone to repair it, which is more convenient

You can call Brother Property to report the problem. Find a professional to come to deal with the problem.

This may be due to a problem with the range hood, check this is good.

If the smoke exhaust in the public flue is not smooth, there should be a problem in the smoke pipe, and it can be dredged.

The common flue should be checked to see if there is something wrong. And the maintenance personnel came to check.

Cause and solution reason 1 The check valve on the range hood and the independently sold range hood check valve mostly adopt the structure of wind opening of the range hood and the self-weight closure of the valve, and a small part of the valve is equipped with a spring to help the valve close. In order to ensure that the wind power of the range hood can blow open the check valve, the weight of the valve or the spring force should not be too large, so the closing force of the valve is small, and the valve is easy to be adhered to oil scale. After the valve plate is adhered to the check valve, the opening and closing are not in place, and the consequence of not opening in place is that the exhaust is not smooth and the air volume is attenuated; The consequence of not being able to close it properly is that a large amount of oil smoke backfills will occur.

Reason 2 The check valve of most range hoods is designed to arrange an annular seam between the valve plate and the valve body, the purpose is to reduce the contact area between the valve plate and the valve body, so as to reduce the adhesion of the oil scale and ensure that the wind power of the range hood can blow the valve open. If the annular seam is too large, when the neighbor turns on the range hood (sewage discharge), the local pressure in the shared flue increases, and the sewage gas is poured from this annular seam nearby.

Reason 3 At present, many new buildings do not use the mother and child flue, that is, the main and auxiliary common flue, the vertical flue commonly used, even if the main and auxiliary common flue are used, when the pressure of the main air duct rises to a certain extent, the auxiliary flue connected with the range hood is in a negative pressure state, and the oil smoke backflow will not occur. However, if the negative pressure is too large, the valve plate of the check valve will be sucked open, and the valve plate after suction can not be effectively closed if it is adhered to the oil scale, and when the pressure of the main flue decreases, the negative pressure of the auxiliary flue disappears, and the oil smoke backflow occurs.

The reason for poor smoke exhaust The oil scale accumulated on the check valve increases the weight of the valve plate, and the opening resistance of the check valve increases after the spring is installed on the valve plate, and the range hood consumes part of the air volume to overcome these resistances, causing the exhaust air volume to decay and the smoke exhaust is not smooth.

Solution: Understand the cause of fume backfilling and poor smoke exhaust, the solution is easy, you can install a tightly closed, open check valve at the air outlet of the range hood to eliminate the backfilling and poor smoke exhaust.

If the kitchen at home has poor smoke exhaust in the public flue, you must quickly find someone to repair it. In fact, we often get this kind of thing in our daily life: when we get home, we can smell the food upstairs and downstairs, especially in the kitchen, but when these smells quietly arouse our taste buds, we don't necessarily have to notice the problem, which means that there is a problem with the flue smoke exhaust.
