Air valves for ventilation: types, mounting, reviews

The device of the ventilation system may provide for different design versions. For the maintenance of small rooms it is recommended to use valve mechanisms that ensure the inflow and exhaust of air flows. As a rule, these are compact devices, due to which the user relieves the kitchen or technical room from unwanted elements in the air environment. On the market, air valves for ventilation are available in various versions, including automated control systems.

Supply air valves

This is the simplest solution for organizing a fresh air supply system. A valve of this type is usually used in rooms where there is exhaust or natural ventilation. In this case, a classic membrane valve for air flow is not practical to use in places where there is a forced ventilation system. In this case, double injection of air masses will be ensured, which may be superfluous.

By design, such models are most often cylindrical devices with filters that can be integrated into a wall niche or a window system. In addition, the supply valve can be supplemented with automatic airflow control systems, which independently of the user adjust the operating parameters to the optimum mode taking into account the weather conditions.

Types of air supply valves

All models can be divided into several categories depending on the addition of functional devices, control systems and approaches to installation. First of all, it is necessary to divide the ventilators into conventional and noise-insulating ones. For the most part, the air valves for supply air ventilation provide protection against extraneous noise. For this, the filter layer is supplemented with a special insulating material. Also, the valves are divided according to the possibility of regulating the inflow. Traditional devices are not managed in any way - as a rule, they are cylinders with cleaning filling, which work in the same free air supply format. In turn, adjustable modifications can provide not only automatic control of throughput, but also manual. To do this, the outer part of the valve is equipped with a special closure, which can be changed position.

In addition, the supply valve can assume different installation possibilities. Thus, manufacturers of window systems increasingly form in their designs special openings, in which it is easy to integrate valves. The classical design can only be built into walls and partitions.

Check Valves

If you need a system to remove the exhaust air, it is better to refer to the models of the reverse action. The basis of these devices are two blades, which in the course of work regulate the characteristics of the drawing of air currents. The body can be represented by a cylinder or a channel of a rectangular shape - this nuance should be calculated initially, so that the design optimally approaches the parameters of a particular installation site. Unlike the inlet models, which are a membrane valve with filtration, in this case the emphasis is on the function of the fan, which literally delivers the waste mass to the working blades. That is, in the non-return valves the filtration membranes are not needed, since the system is not designed for supply function with the injection of fresh air. Moreover, as a supplement, such structures can be equipped with protective gratings and noise suppressors.

Types of reverse action valves

The principal difference of such systems is the method of location. If the optimal configuration of the plant for the supply valves is horizontal, the non-return valve systems can also be installed vertically. But it is important to take into account the supply channel and the possibility of its connection, since the non-return valves for vertical ventilation are installed in the ceiling openings. Also devices are distinguished by material and section. From the point of view of comfort, it is desirable to use plastic models, and to prolong the service life, metal systems are preferable.

Valve control systems

There are three main approaches to the implementation of the air valve control system. The most effective is an air valve with an electric drive, in the design of which a fan is provided. The operation of such a system can be controlled remotely by a remote control, and by installing a special program with certain bandwidth parameters.

The second option is the hygro-controlled mechanisms, working on the principle of changing the position of the flap. Such models are supplied with polyamide tape sensors that monitor the moisture content of the air and, in accordance with these values, adjust the position of the leaf. This principle of regulation can be guided by the indices of the microclimate in the room. The third category of control systems is represented by manual mechanisms. If the air valve with electric drive changes the position of the leaf by means of an automated mechanism, then in this case it is supposed to participate in the correction process of the user himself.

Installation work

Installation is carried out by two technologies. As noted above, in most cases the valve is integrated into a wall or bulkhead, but the installation scheme in the window structure can also be used. The first option involves the creation of a hole in a concrete or brick niche by means of shtrobleniya. As a rule, this operation is performed by specialists. The valve is installed in the formed opening, and the space around it is filled with mounting foam. In the window constructions, the air valves for ventilation should preferably be integrated, provided that the standard sizes are compatible. The optimal option will be the acquisition of a complete set of window systems and a vent valve. In a regular double-glazed window such a device can not be installed. Especially for the installation at the stage of the process of manufacturing profiles, small openings are formed, into which the valves are mounted using metal fasteners.

Reviews of manufacturers

Typical solutions for use in private homes offers a wide range of company "AVK-96". Users of this product emphasize that the valves are long and do not require special care. True, most systems of this company are designed for manual control, which is not suitable in all cases. A more modern air vent valve can be found in the Krrut range. The developers of this organization supply devices with electric drives from the world leaders of the segment - Belimo and Polar Bear. Owners of such valves also indicate high reliability, which is supplemented by a wide range of functions and ergonomics.

Conclusion

Do not forget that the valve is still an additional means of updating indoor air. Its function can be as auxiliary to the basic systems. In particular, apartment ventilation, represented by an infrastructure with natural air circulation or an exhaust system, may well be combined with such a valve. At the same time it is necessary to calculate the operating format of this device. If it is planned to use it by the seasons, it is better to prefer the inflow model with manual adjustment. Modifications of systems with reverse air supply are more often used as year-round ventilation, so for convenience of operation it is worth giving preference to versions with automatic control.
