Purpose of the supply valve

Wall air valves are designed to supply a clean, fresh outdoor air into the room. These devices do not go to any comparison with the open window that let in not only fresh air jets, but also all the noise, the dust from the street.

Valve equipped with acoustic system layer, flows into the room only clean air jets.

If we compare with the wall pritochnik window vent valve, It is more profitable. It is expressed in the fact that it does not reduce the light transmission characteristics of windows, running under all temperatures, even understated. Moreover, functioning autonomously, effectively prevents condensation. Mounting it takes only a few hours.

Supply valve in the wall

Supply valve - a device simple and inexpensive, but very functional. If you position it over a radiator, the air coming into the room to be warm

These devices have become popular after the old wooden windows have become massively changed to plastic. New window units have significantly improved insulation characteristics, but also fresh air into the room was a small amount of flow. Inadequate ventilation has created a problem with high humidity.

Heat in tandem with moisture creates excellent conditions for the replication of mold, fungi. First, their colonies appear in hidden places - under the wallpaper, tiles other finishing materials.

When propagated by colonies of microorganisms become visible, fight mold is becoming increasingly difficult - you have to destroy the old finish and replace it with a new one.

Design features of the valve wall

The design of the valve is extremely simple.

Its main elements are:

  1. ductwork - plastic pipe. According to it, the air from the yard into the room. Its length must be greater than the thickness of the wall.
  2. inner case in the form of a cylinder. Most often it is made from plastic. The diameter of the housing ranges from 6-13,3 cm.
  3. Filter - a layer of polyethylene foam. It is located within the housing and is designed to guide the air stream into the room.
  4. Protective cover. It is located at the entrance and is a barrier to the penetration of various materials in the room.

During the cold outside the tube can be coated with icing. Condensation or freezing it leads to the formation of ice crust and reduce the diameter of the supply valve.

In order to prevent this process is set pivotable cover. Since the condensate through the apertures therein flows downwards, the ice is formed does not peel.

The design of the supply valve

Some models have a supply valve duct, complete with a fan for forced ventilation (+)

Ducts individual products are equipped with a heater-shumoizolyatorom of polifoma. It reduces noise and prevents the wall around the body from freezing.

The wall may have a manual valve or an automatic adjustment. Second gigroregulirovaniya equipped with a sensor which determines the level of humidity inside the room. Above this index valve is slightly opened, and the air mass comes inwards to a greater extent.

The degree of opening of the channel can be seen on the scale located on the valve center pole. Adjustment is carried out continuously until the complete closure of the ventilation stroke.

Some more sophisticated intake valves manufacturers equip heat exchanger for heating the air mass. Sometimes there is a remote control kit that controls the heater and fan.

Parameters selection of wall pritochnikov

Each valve model has its own characteristics. They are distinguished by the cross section of the duct, the presence of such an option, as the complete closure device. The design provides for the possibility of some noise insulation installation, while others can not.

The work of some mechanisms regulate manually, but there are also models with automatic adjustment. Models of air-supply performance of various valves have different diameters, so house provide clean air at different volumes. Various air-supply valve and the length and material from which they are made.

design tip

The tip structure includes a filter and a valve. The first element is used for air purification, and the second - to coordinate the volume of air intake (+)

Headroom its inner part is inserted into the channel and attached to the wall using screws through the gasket to seal. Wall ventilator needs periodic maintenance.

Outdoor grill at least once a year on clean. Once a quarter to clean the filter in the center pole. At least once in 6 months, you need to clean pipe in the wall, using a vacuum cleaner.

Choosing supply valve must be checked, it is designed for a temperature range. Otherwise, in the event of a breach of this condition, it just will not be able to function fully.

The length of the supply valve

It is also important to choose the right device for the length - the indoor unit must pass through the wall through

There are two types of valves: air infiltration and for ventilation. They have the same function - supplying the building with fresh air.

Infiltration valve operates autonomously, it does not need to monitor. He is almost imperceptible, effectively warms the air. You can install it both during the construction of the building, and in the wall of the house where people live for a long time.

Where to install air inlet

There are three main options for the supply valve assembly:

  1. On the heat source. In this case, the outside air comes into the room is already heated and stimulated his convection.
  2. At a height of 2/3 of the window, Which is about two meters from the floor and at a distance of 0.3 m from the slope of the window. The air mass is directed to the ceiling, where it is mixed with the warm room air.
  3. In places with high moisture. This may be a corner of the house, have already started to mold.

Wall vent is installed not only in the walls of private homes, but also used to improve ventilation in the apartment. they often put on the lower floors of apartment buildings - the best place is the space between the window sill and radiator.

Demand for these devices in children's institutions, where the fresh air is especially important. With such a construction provide the optimum indoor climate for keeping animals and birds.

Place the valve installation

Ventilator or supply air handling unit can be installed on any wall. The valve does not affect the structure of the walls and spoils the appearance of the facade

It is a mistake to think that installing a valve, you solve a problem with a lack of fresh air. This is possible only if its structure is included a device for forced ventilation. When it does not, the air is a result of the pressure difference between inside and outside.

One wall valve with a pressure drop in the range of 10 Pa, which occurs in normal conditions, ensures the supply to 30 mᶾ / h. It is normal for one person.

In larger pressure difference, and increases the amount of air entering the room. Therefore, to achieve the desired effect, you have to install another valve further or forced ventilation.

Produce and intake valves, which are inserted into the ventilation shaft. This is usually done in the bathroom, in the bathroom, kitchen. Before their installation should be tested traction. To do this, check for air flow when open window, using a lighted match, badged the hole.

Check exhaust efficiency

If it turns out that the existing ventilation is functioning badly, and installed in the wall of the supply valve will not guarantee the supply of fresh inflows into the extent to which it is designed

These manual methods of verification can not work in the hot season. The hot summer sun, the air is heavier than in the cool. Because of this pressure drop in the duct, even when the system operates satisfactorily, flame or paper sheet will not be attracted.

In addition, it is worth considering the following rules:

  1. If the cross-supply valve is quite large, and its design is not is adjustable, you can not install two such devices face each other. In winter, when ventilation is functioning most actively due to inequality of pressures inside and outside, will be drafts.
  2. Valve cover should stay in a free space between the sill and radiator. If the radiator poluteply, the air entering through a valve without adjustment, will not have time to warm up and the room temperature drops. And when insufficient supply air will have to think about additional venting.

When you select on the front of the valve installation site, it is necessary to take into account, where the wall is directed. Better when the air intake is not from the street, where there is an active movement of vehicles, and from the yard.

How to perform the installation of the valve itself

The most difficult thing in the installation of air inlet valves - the creation of a through hole in the wall. If it is provided by the project, the work will not at all complicated. When the house was built and planned installation of air-supply valve in its walls have to do it yourself or hire a specialist.

this work permit is not required, since regulations are allowed to do in the supporting wall without any approvals airhole single section up to 30 cm. Cut a hole in the wall in two ways.

Drilling holes first method

Most often used for drilling the hole puncher. First wall mark out circuit, adding to the cylinder diameter with a tolerance so that the body has passed through the hole freely. Since the wall thickness of the carrier usually varies in the range 40 - 100 cm, in the same range is selected and the length of the valve.

drilling fixtures

If the concrete body comes valves, it is drilled drills for metal

The next step - drilling a number of small holes 10 to 12 mm on the outer contour of the circuit. The distance between these holes about 10 mm. Further, between the knock holes using a hammer and chisel residues material.

Hole ideal shape manner to receive will not be able, in addition, there may be chipped, cracked on the wall.

The second method of drilling holes

Quickly and efficiently as possible to get a hole using a diamond drill.

Used in this drilling rig, complete with diamond-drill bits, replacing the drill, equipped with:

  • powerful engine;
  • drilling drive;
  • a set of core bits with different diameters;
  • rack rail, fixed to the frame.

Due to the fact that in the drilling zone automatically enters the water for cooling the tool, and at the same time the dust is washed away. Hole in the wall will have the exact dimensions and absolutely smooth surface inside.

Step by step description of the diamond drilling process looks like this:

  1. Mark a location for the drill rod. To do this, on the wall lay a segment equal to the distance between the anchor base and crown.
  2. Technological drilled hole using punch.
  3. Fixed machine frame by first drive the anchor into the vessel opening. To stand not damage the wall, enclose under it a piece of soft material.
  4. Secure the film up to the floor and about 300 mm width under the seat, intended to be fitted a rubber cuff. This will prevent contamination of the coolant wall.
  5. Insert sleeves into the body of the drilling machine, where this special place provides. Further, the hose is connected to the outflow of the coolant, having spread it on the sleeve and securely fixing collar.
  6. Consistently collect burmashinu. At the end of wear corresponding diameter diamond crown. Connect the water supply hose to handle the installation.
  7. After reaching the working pressure of the pump by pumping with a manual pump, waiting until the full speed setting dial, and begin drilling. At this time, the cooling liquid irrigates the drilling location, not only cooling the tool, but also removing the dirt.

When the wall thickness exceeds 50 cm, length of the crown may not be enough to drill through it in one portion. Therefore, in the first step of the crown emboss concrete core, and then mount extender and continue the process.

Drilling holes for the valve

After switching on, the crown closer to the wall until all contact with her. After that, do not apply pressure on the knob - it can lead to the breakdown of the teeth on the working of the diamond tool

After completing the drilling, dismount the installation in compliance with the reverse sequence. Wet concrete dust under the collar is removed with a damp cloth.

Installation of the supply valve

Preparing the hole, start with the installation of the valve. For this channel for infiltration drive in the place intended for it flush with the outside wall.

Pre-insulated pipe wrap. Inside the pipe should protrude a little room. The remaining free space in the hole zapenivayut, and inserted into the pipe insulation. She will protect and noise.

Adherence to the slope

When drilling holes for through-air inlet to be met 3⁰ about bias in the yard. If you do not meet this condition, the duct will accumulate moisture

The next step is to install the lattice. The seat on the lattice and on the outer wall is coated with silicone, then it is inserted into the duct. Further, mounted inside the valve, after having put on the landing place of silicone. Fastening the washer to the inner wall of the filter installation of the valve for the inflow of process ends.

Popular models of air-supply valves

Particularly popular among consumers supply valve "Domovent". Its labyrinth shape allows coarse filtration followed by air masses jet direction on the heater. It is equipped with mechanical control air supply and the filter does not require periodic replacement.

Demand and model CPW 125Manufactured by domestic producers. Since its length ranges between 400-1000 mm, we can always choose a suitable enclosure to be installed in a wall. Outside this ventkanal closed lattice cast aluminum of circular cross section with a mosquito net situated behind the bars.

Similar valves are produced in Finland, but their value is higher than the domestic half. Products from China also have on sale and they are cheaper, issued in Russia. Good characteristics differ Italian valves KIV Quardo. They feature a square-shaped head part, which distinguishes them from the Finnish counterparts.

KIV valve assembly

KIV valve produced in two versions - a head part in the form of a square (QUADRO) and circular. Origin looks more aesthetically pleasing (+)

Rectangular duct wall are valves CRS-75. Improved embodiment of the supply valve is a breather "Tion O2". It has a rectangular shape, small dimensions and is equipped with heating, so it can be operated at low outside temperatures.

When drilling the wall for some reason can not be done, then to improve the atmosphere in the room, you can use conditioner air influx.
