Exhaust valve for kitchen or bath: review

Ventilation is necessary for any room, but for the effective operation of this system it is important to know what kind of equipment to use and where to install it. For example, in bathrooms and toilets, these devices need more other things. Many manufacturers today offer home exhaust fans, which have different capacity. When choosing, it is important to pay attention not only on this feature, but also on the method of administration, which affects ease of use and cost. There are mechanical and electronic models, but they can have a status indicator on the panel.

Usually they have a check valve and solve the problem arising due to high humidity. But to buy any device – does not mean to solve the problem. It is important to choose the right unit to the exhaust fan to cope with unpleasant smells and high humidity. In order to determine the choice, it is necessary to consider several models.

Features place the valve on the cooker hood

If you decide to install a check valve on the cooker hood, you should be aware that the system may have one or more air intake. Latest on the ventilation duct will go on the street or in the mine. To avoid reverse thrust enough is the only valve located in the duct.

If the system is more complex due to the presence of several vents and hoods for natural ventilation, it uses slightly different rules of placement of the valves. First, each branch will need to install such a device. This is needed to avoid redirection of air into the exhaust when it is idle. Second, install a check valve on the hood provides for the presence of another device at the outlet of the ventilation system. When a complete sealing of the channel this is not necessary, but practice shows the validity of the installation of the valve in this location.

Third, the device must be located at the point which would be easily accessible. This is because the equipment requires periodic cleaning from fat and adhering dust, otherwise the damper will be fully closed during reverse thrust.

Near the entrance to the mine of an apartment house it is necessary to pay special attention to the installed valve. The General ventilation system – this cavity with positive temperature, protected from sunlight. There periodically receives wet air, which creates ideal conditions for microbial growth. There is often inhabited by rodents, birds and insects. The air in these mines is seldom consistent with the requirements that apply to the residential premises. Even in the case of regular carrying out of sanitary processing of the mine to exclude the possibility of penetration of air into the apartment through the reverse thrust.

Non-return valve for the hood in the kitchen can be installed with the need of variable work forced and natural ventilation. In this case near the ventilation grille is installed the tee and the valve is on the outlet for natural ventilation. Another solution is the usage of special design in the form of a lattice with two holes for both types of ventilation.

Features of the valve manufacturers

Despite the fact that the price is not high in the check valve on the hood, with his own hands to make it too. This should ensure you have:

• Ventilation grids;
• Soft records;
• Melt the glue.

As for the plates, as they may act as film from the x-ray apparatus. On the inner side of the lattice it is necessary to glue plates to they were fixed on the oppositeparties. The middle parts should move freely. This device is the most simple non-return valve. The grid is set in place, but it will work, not letting the air out of the mine.

In conclusion

A Fairly common phenomenon - the occurrence of reverse thrust, which leads to many negative consequences. Installing the vent valve, you will be able to solve this problem. Before purchasing such a device it is important to understand its structural features.

Among the other varieties should be allocated to single-gravitational devices in which the flow of air from the room will exert pressure on the sash. In the absence of motion it closes. Another form are bicuspid valves using springs. They are also called butterfly have in the design of the 2 blinds, folding under excess pressure.
