Definitions
- the present invention relates to a device for adjusting an air flow, in particular a supply air valve or an exhaust air valve.
- Air distribution networks are used particularly in buildings for ventilation and partly for air conditioning of rooms.
- Controlled residential and office ventilation systems are now sophisticated systems that use centralized or decentralized ventilation devices.
- the wall, ceiling or floor openings of a building have air outlets with inserts that are connected to the air distribution network. Such air outlets change the shape of the air flow and/or they regulate the air volume flow. Some of the inserts allow the air flow to be adjusted. They are called supply air valves or exhaust air valves depending on the direction of flow into or out of the room. They limit the cross section in the air duct, although the size of this limitation can be partially selected.
- Supply air valves i.e. valves through which air flows into a room, often have the disadvantage that they do not distribute the outflowing air evenly. A person sitting or lying down who is directly exposed to the escaping air may find this uncomfortable.
- Exhaust air valves ie valves through which air flows out of a room, often have a different shape than supply air valves, which leads to a rather busy appearance in the room. Furthermore, such supply air and exhaust air valves can often not be adjusted when installed or can only be adjusted with relatively great effort. Another disadvantage is that individual components of the valve protrude into the room to different extents depending on the degree of adjustment of the valve, stand out from the building wall and impair the visual appearance of the room.
- WO 2022/101056 A1 discloses an air volume throttle valve with air guide bodies in the form of blades of a rotor.
- the air guide bodies are each formed from a first and a second air guide unit, which can be rotated relative to one another, so that the distance between the air guide bodies and thus the flow-through cross section of an air duct can be changed.
- This device enables the free flow cross section to be changed while the narrowest flow cross section remains the same. This makes it easier to control the valve.
- the device according to the invention for adjusting an air volume flow in particular in an air distribution network, has a central air duct with a flow-through cross section and a throttle arranged in the central air duct, the flow-through cross section being changeable by means of the throttle.
- the device also has an inner flow element with a jacket, the circumference of which increases in the direction away from the throttle.
- the central air duct has a taper in the area of the flow element and a subsequent further expansion. This creates a curved flow channel between the jacket of the inner flow element and the renewed extension, which ends towards the outside of the device.
- the taper is preferably located at a distance from the throttle.
- the separation of the inner flow element and throttle as well as the design according to the invention of the central air channel in the area of the inner flow element enable the formation of a flow channel whose flow cross section is Changing the throttle setting remains unchanged.
- the flow cross section of the flow channel is constant over its entire length or it changes along the direction of flow. The taper and the subsequent further expansion influence the flow distribution in a positive way.
- the constant flow cross section usually faces away from the throttle and towards the building space. In the case of a supply air valve, this is the outflow or outflow cross section. In the case of an exhaust air valve, this is the air inlet cross section.
- the constant flow cross section simplifies measurement of the volume flow, since a clear assignment of an aerodynamic force or another measurement variable proportional to the flow velocity is possible depending on the volume flow.
- the separation also enables the device to be designed in the area of the inner flow element independently of the shape of the throttle. In the case of a supply air valve, the flow distribution of the air flow into the building space is optimized.
- the inner flow element expands towards the building space.
- the central air channel tapers and widens again, creating the curved flow channel between the inner flow element and the extension. This results in a supply air valve with an air flow that is deflected in a radial direction.
- the device has a housing which forms the central air channel and which has an inner wall which forms the taper and the renewed expansion.
- the housing is essentially circular cylindrical in shape.
- the housing preferably has a circumferential first guide surface, a circumferential second guide surface and a projection lying between them.
- the first guide surface faces the throttle and the second guide surface preferably extends parallel to the outer jacket of the inner flow element.
- the curved flow channel preferably has a cross section that remains the same when the throttle setting is changed. On the one hand, this improves the visual appearance because the valve always looks the same. Furthermore, there are more options where a sensor element can be placed to determine the volume flow. Since the flow channel extends over a noticeable length, the radial deflection of the outflow is optimized.

- Measuring unit 623 snap element
