Abstract

FIELD: heating.

SUBSTANCE: aeration device is designed for natural ventilation systems of architectural monuments. The aeration device comprises releasably connected louvre module casing with a louvre grid and valve module casing with at least one damper with the damper suspension unit and the damper deflection angle limiter with a return spring. The damper deflection angle limiter is made as at least one arrester rigidly connected to the rod and controlled by a rope; the rod is set in the guide bushes welded to the valve module casing and the damper suspension unit is fitted by a stopper interacting with the arrester.

EFFECT: increased reliability of temperature-humidity conditions normalisation, elimination of stagnation zones, removal of excessive air from the building inner volume.

Description

This technical solution relates to technical objects used in natural ventilation systems of church and civil architecture monuments to normalize the temperature and humidity conditions, eliminate stagnant zones, and remove excess air from the internal volume of the building. It can also be used in industrial buildings, especially in workshops with high temperature.

It is known aeration device with a single-acting exhaust valve device in a traditional design, consisting of two modules - a valve module and a non-blown shutter module, which are detachably connected. Aeration device is installed in the upper part of the window opening. The valve module consists of a housing, dampers, dampers suspension device. The movable dampers are single-acting devices - this means that the dampers open only when there is a pressure difference. The louvre module consists of a housing and transparent louvres, RU 2262642 C2, 10.20.2005.

The disadvantage of this device is the inability to change (adjust) if necessary throughput:

- by the periods of the year (winter, summer, ...)

- in connection with the change in the microclimate of the monument in the process of the monument leaving the emergency state, etc.

The closest in technical essence to the described invention is an aeration device comprising a detachably connected louvre module housing with a louvre grille and a valve module housing with at least one damper with a damper suspension device and a mechanism for limiting the deflection angle of the damper with a return spring. SU 1497433 A1, (State Design Institute “PROJECT PROMENTILATION”), 07/30/1989.

The disadvantage of this device is the impossibility of manual adjustment, which allows you to change the area of the passage section of the aeration device.

An object of the invention is the creation of an aeration device with manual adjustment of the change in the area of the flow area of the aeration device.

The problem is solved and the technical result is achieved due to the fact that the aeration device comprises a detachably connected louvre module housing with a louvre grille and a valve module housing with at least one damper with a damper suspension device and a mechanism for limiting the deflection angle of the damper with a return spring, this new is that the mechanism for limiting the deflection angle of the valve is made in the form of at least one limiter rigidly connected to the rod and controlled by a cable, etc. This rod mounted in guide bushings welded to the housing of the valve module and damper suspension device is provided with an abutment cooperating with the stopper.

Figure 1 shows a General view of the aeration device.

Figure 2 shows the housing of the valve module and the louver module assembly with the shutters closed.

Figure 3 shows the housing of the valve module and the louver module assembly with open shutters.

Figure 4 shows the mechanism for limiting the angle of deflection of the dampers.

The aeration device comprises detachably connected housing 1 of the louvre module with a grill 2 louvres and a housing 3 of the valve module with at least one damper 4 with the device 5 of the suspension of the damper 4 and a mechanism for limiting the angle of deflection of the damper with a return spring 6. The mechanism for limiting the angle of deflection of the damper is made in the form of at least one limiter 7, rigidly connected to the rod 8 and controlled by a cable 9, while the rod 8 is installed in the guide sleeves 10, welded to the housing 3 of the valve module, and the device 5, the suspension of the shutter 4 is provided with a stop 11 interacting with the limiter 7. In addition, the device may include a seal 12 and a cable fastening device 13.

Aeration device operates as follows.

In the initial position, under the action of the return spring 6, the rod 8 with the stops 7 is in its highest position (according to the drawing), the stops 11 of the device 5 for the suspension of the shutter 4 do not contact the stops 7 and, in the absence of air flow, the shutter 4 is in the closed position. If air flow occurs, the shutters 4 can deviate by any angle (φ), up to the maximum angle (φ) of the deflection of the shutters 4. If necessary, using the mechanism for restricting the deflection angle of the shutters, you can set the maximum deflection angle (φ) of the shutters 4, which will determine the area of the flow area of the aeration device. To do this, use the cable 9 to compress the return spring 6 and fix it in a predetermined position. In this case, when the air flow occurs, the shutter 4 can deviate only by a strictly defined angle because the angular rotation of the shutter 4 will be limited by the stop 11 in contact with the restrictor 7, therefore, when the pressure on the shutter 4 increases, there will be no increase in air flow through the passage area aeration device.

By changing the position of the restrictor (s), it is possible to change the maximum angle (φ) of the deflection of the dampers 4, and hence the passage area of the aeration device.

Figure 1-4 shows a variant of the aeration device with a mechanism for limiting the maximum deflection angle of the shutters 4, manually actuated by means of a cable. Instead of a cable, it is also possible to use an electric actuator switched on remotely to control the position of the limiter (limiters).
