The floor where the family lives is high, how to solve the problem of e liquid backfilling?

As the residential area is covered higher and higher, the flue is also a public place, and it is necessary to have sufficient circulation to ensure that the airflow through the public flue is relatively smooth. The space of many public flues in high-rise buildings is indeed limited, the approximate area of the building flue is thirteen square centimeters, and in this very small space, if you want to solve the maintenance of dozens of households, the exhaust pipe can only reach fifteen square centimeters, which belongs to the area of the public flue. The emission also makes everyone unable to do so, so the public flue will be prevented from backfilling.

When decorating, many owners hope to avoid this phenomenon to improve the effect of flue smoking, but under normal circumstances, when cooking during peak hours, a large number of oil smoke will continue to avoid traffic jams, which will lead to oil smoke backflow. offIn terms of smoking effect, the highest technical indicators of the core of the range hood are still considered, so special attention must be paid to the purchase of the range hood in this case. Especially now that the cooking fumes are very large, and the public flue needs to be used for a long time, there will definitely be an increase in pollution.

The critical time will still depend on the development of the technical content of the range hood. <>

For the owners of high-rise buildings in public places, the area of the flue is very small, and the pressure is also very large, which will not only have high requirements for the range hood, but also have high requirements for wind pressure. That is, the flow of water in the canal depends on the area of the water and the speed of the flow of water, and the principle of the range hood is the same, whether it is the wind pressure or the area, it can determine the speed of discharge. <>

Although the area of the public flue is limited, especially when everyone smokes at the same time, the pressure is very high, which will cause backfill pressure and increase the air volume of the smoker. To avoid this phenomenon of oil smoke backfilling, in order to take this kind of sealing measures, the oil smoke emission can be smooth, it is recommended that you install a check valve when decorating to alleviate this problem. Then it is necessary to buy a smoke machine with relatively large smoke power, which can ensure the dredging of the pipeline and timely suction.

To check the inlet and outlet of the hose, be sure to install a check valve to prevent convection from occurring, so that backfilling does not occur.

Glass glue can be used, or check valves can be used, both of which can improve this problem, saving money and convenience.

When such a situation occurs, you should seek the help of professional and technical workers, because this situation is also more serious, and it is likely to lead to a full house full of oil smoke.

The floor where the family lives is relatively high, and a check valve should be installed if there is a backflow of e-liquid.

to resolve. Buy a well-sealed check valve from the market or online.

Then install it on the range hood.

The outlet is wrapped tightly with raw tape or sealing tape to prevent oil smoke from entering the room. In order to deal with the phenomenon of oil fume backflow upstairs, an electronic oil fume valve can be used. The electronic hydraulic valve will not be polluted by oil stains, and is driven by electricity and has strong power.

Installing an electronic range hood valve at the outlet of the range hood can avoid the backflow of oil smoke.

1.The return of oil fumes mainly occurs in high-rise buildings that use public flues.

The developers have also taken a lot of measures in this regard. At present, the flue is basically divided into the main flue and the auxiliary flue, and its main function is to guide the upward discharge of oil smoke and reduce the odor. If the check valve is installed in place, closed tightly, and opened in place, it can well solve the problem of oil smoke backflow and poor smoke exhaust.

The check valve installed in the flue and on the range hood is opened by the wind of the range hood and closed by the gravity of the valve plate.

2.Installing a check valve in the air outlet area of the range hood can eliminate the problem of backflow of oil smoke and poor smoke exhaust. Or you can modify the inlet of the range hood hose and change the air inlet to the position of the auxiliary flue, which not only slows down the rising speed of the oil smoke, but also increases the resistance; Sometimes the doors and windows of the kitchen are closed too tightly, resulting in less air pressure in the kitchen than in the flue.

If someone else's e-liquid is poured in, you can only open the doors and windows to solve it.

3.If the windows of your range hood are not open when it is working, air convection cannot be formed, and the oil smoke cannot be discharged at all. When the range hood is not working, if you don't open the window, the air pressure in your kitchen will be less than the air pressure in the flue, and other people's oil fumes will inevitably pour back into your home.

Try to choose wind pressure.

High hood products. It is said that the integrated stove.

It can effectively solve the problem of oil smoke reflux. When the hood is activated by the integrated cooktop linkage system, the anti-fume damper opens, and when the machine is closed, the anti-fume damper closes automatically. The above is the answer to the problem of how to solve the problem of e-liquid backfilling when the floor of the home is relatively high.

When there is a backflow of oil smoke, you should ask professional personnel to come to repair it as soon as possible, and replace the range hood of your home, clean the range hood regularly, and lay the corresponding pipes again to strengthen the suction.

If there is oil smoke backfilling, it is generally necessary to sort out your own smoke exhaust system, and dredge the pipe, modify the range hood hose inlet at home accordingly, and install a check valve on the smoke outlet pipe of the range hood.

A check valve can be installed, or a sagging range hood can be selected. Clean the flue regularly, and also pay attention to the quality of the integrated stove.

Installing a check valve in the air outlet area of the range hood can eliminate the problems of oil smoke backflow and smoke exhaust; Or you can modify the inlet of the range hood hose and change the air inlet to the position of the auxiliary flue, which not only slows down the rising speed of the oil smoke, but also increases the resistance; Sometimes the kitchen doors and windows are closed too tightly, resulting in the kitchen air pressure is smaller than the flue air pressure.

If you want to completely solve the problem of oil fume backfilling, you need to install a check valve, and it must be sealed, otherwise it is easy to cause oil smoke backflow.

A check valve can be installed at the air outlet of the range hood, which is used to eliminate problems such as oil smoke backflow and smoke exhaust; It is also possible to modify the inlet of the range hood hose and change the air inlet to the position of the auxiliary flue, which not only slows down the rising speed of the oil smoke, but also increases the resistance; Sometimes the window is not open, and the kitchen air pressure is less than the flue air pressure, so you can open the doors and windows to try it.

There are four major reasons for the occurrence of oil smoke backfilling, which are as follows:

1: Because the smoke machine comes with the air outlet check valve and the flue mouth installed drooping closed valve are dependent on the smoke machine wind power to open, the valve piece of the weight or the installation of a power spring to close the structure, in order to ensure that the smoke machine wind can blow the valve, its weight or spring force can not be too large, so the valve closing force is small, the closure is not tight.

Two: most of the smoke machine comes with an air check valve between the valve plate and the valve body has an annular seam, when the neighbor opens the smoke machine (drainage), the local pressure in the shared flue increases, and the sewage gas is poured from this ring seam nearby, and the oil smoke of the old-fashioned flue is poured for this reason.

Three: When the appropriate wind speed passes through the common flue, an appropriate amount of negative pressure will be generated at the interface of the hood, so that the kitchen air flows to the flue, so the oil smoke backflow will occur.

Four: When the smoke exhaust pressure and air volume of the upstairs smoke machine are large, it will produce wind resistance in the main flue, which increases the local pressure of the downstairs flue and blocks the normal smoke exhaust of the downstairs residents, which is the reason for the upstairs cooking and downstairs backfilling.

This situation often occurs on the public flue and is difficult to eliminate, so it is recommended that the range hood should not take the flue.

The main reason is that the one-way check valve of the range hood fails, which is generally one at the flue mouth and one at the outlet of the range hood, but with the use of a period of time, due to the oil smoke, the opening and closing will be abnormal, resulting in the backflow of oil smoke.

I have encountered five companies that have this situation, and coincidentally, the brand of range hood used is the same - Shuaikang.

Because the newly built residential buildings are all flue pipes that prevent backfilling, when the fume backflow occurs, a closed valve can be installed at the flue mouth (wall) to solve the problem, if the closed valve has been installed at the flue mouth and still backfill, you can only replace the electric fume valve. There are 2 kinds of electric fume valves, one is installed on the flue mouth (wall), and the other is installed on the air outlet at the top of the hood. The electric range smoke valve is a big search on the **.

There are two kinds of oil smoke flavors.

1. Smoke inverted, refers to the public flue, a little ruthless normal, more is that the flue is not installed with an anti-smoke check valve, or the check valve can not be used normally, there is also a plastic check valve on the range hood, but the effect is not very good, the gap is very large.

2.Poor pipe sealing.

Generally, the cooking time of the family is about the same, and turning on the range hood is also considered to be at the same time, forming a pair of smokes, there will be no smoke smell, the more you don't cook, the more the smell of other people's oil smoke will run to your house.

Install a check valve at the flue mouth, my family used to be this, the effect is very good after installation, and finally there is no trouble with backfilling, and the smell of smoke has been solved, hehe, I bought a Lufthansa flue check valve, you can also try it.

For new houses, it should be that the check valve of the flue is broken, or it is not installed. If it can be changed now, if one of the kitchen is an exterior wall, it is recommended to open a hole in the exterior wall and drain it directly, and the hole in the flue is directly sealed, so that there will be no smell.

Check the check valve of the range hood for obstructions.

Check to see if there is a problem with the lower check valve.

Teach you a super simple method: find a plastic bag that is also quite fine with the exhaust pipe, put it on the exhaust pipe head, the length of the pipe is about 15 20cm, you can give it a try, the plastic bag is blown up when exhausting, and the plastic bag is basically closed when it is not exhausted, which can effectively prevent the backflow of oil smoke.

Do not do the smoke machine pour the smoke downstairs of the tank.

This is also the case in my house, you have to install a check valve, and the ordinary check valve can't solve the problem at all, I changed several brands of check valves before, and then found a ten can fly check valve in Jingdong, you can search in Jingdong, it's very good, it's still smart, but I don't know how long it can last.

Fume backfilling is indeed a very annoying and tricky thing, not to mention choking, the home will be oily and greasy by the back-filled fume, so what are the reasons for the back-filling of fume? And how to solve it? In fact, there are two main reasons for the backflow of oil fumes during the peak cooking period If the wind pressure of your hood is not enough, it is at a disadvantage, and you know what the neighbors eat downstairs.

The second reason: the smoking effect of the smoke machine is not excellent, and a smoke machine with excellent smoke exhaust effect is also very important. After all, other people's high-power smoke machines, both in terms of emissions and emission speed, are better than yours, can the phenomenon of backfilling not appear in your home?

You might as well check the exhaust air volume of your own smoke machine, if the effect is not good, change it quickly! For example, you can choose the Consati range hood, which is a century-old brand of German ingenuity, although it has only entered the domestic market in recent years, and its popularity in the country is not too large, but the quality of his home is still obvious to all, the suction power of the range hood is very strong, and the noise is less, and my kitchen is the German Consetti range hood.

1. You can use the check valve, which is divided into flue check valve and range hood check valve, which can solve the problem of shared flue odor, usually the builder will be equipped with a good ventilation diameter of 15cm, and the metal baffle of the eccentric shaft is inside. The process of connecting the smoke pipe of the range hood with the smoke guard you chose is very easy and can be done by yourself at home, but it should be noted that the seams must be plugged with dry plaster.

2. You can also buy a bottle of glass glue, the bottom layer is sealed with glass glue The effect is the best, and the use time will be longer, and glass glue is used where there are seams, so that the fume has nowhere to hide, and can only be discharged directly along the fume pipe.

3. The check valve is best installed when the bricklayer package pipeline, and a good smoke-proof treasure can be as long as the ceiling, and it does not need to be removed in the middle, which can effectively solve the problem of oil smoke in the home.

Generally, a good check valve can be used for a long time, but after a long time, it will fail due to sticky and slow oil stains, and it must be replaced with a new check valve, or removed and cleaned and then installed back.

Change to a manual check valve, open it when you want to open it, and close it when you want to close it.

Seal the common exhaust type cigarette mouth, directly punch the hole, and exhaust the smoke outside.

In a normal place, if you use kitchen utensils normally, you can bear it, or ask it tactfully, maybe he doesn't know if there is a problem with the neighbor's own smoke pipe. Don't face it directly with me downstairs, go straight to the property! People who do not use the normal heating equipment of the residents of the community to cook in normal places, causing the fumes to affect others, he himself does not plan to get along well.

Living in a high-rise house with an elevator, using an open wood stove, cooking and cooking at the interval between the balcony and the living room, cooking and boiling water, oil smoke, firewood smoke straight up.

The oil smoke at home is divided into two types, the first is the oil smoke generated by cooking at home, which can be discharged by the range hood or integrated stove. The second type is the oil smoke that is poured in through the common flue. This situation is more troublesome to deal with, and if you want to solve it thoroughly, you must install a check valve with good sealing performance and "fire prevention" to solve it, because water, gas and fire are more difficult to seal.

If the plastic check valve is installed, it will be deformed when it encounters high temperature, and when the internal pressure (suction) of the flue is large, the valve of the check valve will be sucked open, and it will be stuck by the oil smoke after a period of use, resulting in oil smoke backflow and fire. So far, the best thing is to install an intelligent fireproof fume check valve, which can not only prevent the fumes from pouring in from the public smoke sail chain, but also not be afraid in the face of the flue "fire", which effectively prevents the situation that the public flue "is on fire" and burns to our own home.
