The ventilation system may include various structural designs. For servicing 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 of undesirable elements in the air. On the market, air valves for ventilation are available in various versions, including with automated control systems.
Supply valves
This is the simplest solution for organizing a fresh air supply system. This type of valve is usually used in rooms where there is exhaust or natural ventilation. At the same time, the classic diaphragm 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 provided, which may be unnecessary.
By design, such models are most often cylindrical devices with filters that can be integrated into a wall niche or window system. In addition, the supply valve can be supplemented by automatic control systems for supplying air masses, which, independently of the user, adjust the operating parameters to the optimal mode taking into account weather conditions.
Supply Valve Types
All models can be divided into several categories depending on the addition of functional devices, control systems and installation approaches. First of all, ventilators should be divided into conventional and soundproof. For the most part, air valves for ventilation of the supply type provide protection against extraneous noise. For this, the filter layer is supplemented with special insulating material. Also, the valves are divided according to the possibilities of regulating the flow. Traditional devices are not controlled in any way - as a rule, these are cylinders with cleaning filling that work in the same format of free air supply. In turn, adjustable modifications may include not only automatic control of throughput, but also manual. To do this, the outer part of the valve is equipped with a special shutter, in which you can change the position.
In addition, the supply valve may assume different installation possibilities. Thus, manufacturers of window systems are increasingly forming special openings in their designs into which it is easy to integrate valves. The classic design can only be built into walls and partitions.
Check valves
If you need a system for exhaust air, it is better to turn to reverse action models. The basis of such devices are two blades, which during operation regulate the characteristics of the exhaust air flow. The case can be represented by a cylinder or a rectangular channel - this nuance should be calculated initially so that the design optimally fits the parameters of a particular installation site. In contrast to the supply 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, filtration membranes are not needed in the check valves, since the system is not designed for the supply function with fresh air injection. Moreover, as an addition, such designs can be equipped with protective grilles and noise suppressors.
Types of Reverse Valve
The fundamental difference between such systems is the location method. If the optimal installation configuration for the supply valves is horizontal, then the check valve systems can also be installed vertically. But it is important to take into account the supply channel and the possibilities of its connection, since air check valves for vertical ventilation are mounted in 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 metal systems are preferable to extend the service life.
Valve control systems
There are three main approaches to implementing an air valve control system. The most effective is considered an air valve with an electric actuator, in the design of which a fan is provided. The operation of such a system can be controlled remotely using the remote control, and by installing a special program with certain bandwidth parameters.
The second option is hygro-controlled mechanisms that work on the principle of changing the position of the damper. Such models are equipped with polyamide tape sensors that monitor air humidity and adjust the position of the sash in accordance with these values. This principle of regulation can focus on the indicators of the microclimate in the room. The third category of control systems is represented by manual mechanisms. If the air valve with an electric actuator changes the position of the sash by means of an automated mechanism, then in this case it is assumed that the user will participate in the correction process.
Installation work
Installation is carried out using two technologies. As noted above, in most cases, the valve is integrated into the wall or partition, but the installation scheme in the window structure can also be used. The first option involves creating a hole in a concrete or brick niche by means of gating. As a rule, this operation is performed by specialists. A valve is mounted in the formed opening, and the space around it is filled with polyurethane foam. It is desirable to integrate air valves for ventilation into window structures, provided that the sizes are compatible. The best option would be to purchase a complete set of window systems and ventilation valves. Such a device cannot be mounted in a conventional double-glazed window. Especially for installation, even at the stage of the profile manufacturing process, small openings are formed in which the valves are installed using metal fasteners.
Manufacturer's Reviews
Typical solutions for use in private homes offer a wide range of company "AVK-96." Users of these products emphasize that the valves last for a long time and do not require special care. True, most of the 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 product line. The developers of this organization supply devices with electric drives from world leaders in the segment - Belimo and Polar Bear. Owners of such valves also indicate high reliability, which is complemented by wide functionality and ergonomics.
Conclusion
Do not forget that the valve is still an additional means of updating the air in the room. Its function can be as auxiliary in relation to the main systems. In particular, apartment ventilation, represented by infrastructure with natural air circulation or an exhaust system, may well be combined with such a valve. In this case, it is necessary to calculate the format of operation of this device. If it is planned to use it seasonally, it is better to prefer a supply-type model with manual adjustment. Modifications of systems with reverse air supply are often used as year-round ventilation, so for convenience of operation, it is worth giving preference to versions with automatic control.
