Definitions

  • the invention relates to a louvre flap for use in a line of an air conditioning and ventilation system or a mechanical smoke extraction system (MRA) comprising, on the one hand, a frame which forms a rectangular opening for the flow of a gaseous medium, and on the other hand at least two rectangular slats, wherein each lamella, preferably coextensive with at least one further lamella, is pivotally mounted in the frame between its closed position and its open position about a respective pivot axis, and each lamella has on the one hand two longitudinal edges oriented parallel to its pivot axis and on the other hand two side edges oriented orthogonally to its pivot axis , wherein the pivot axis, preferably in the middle, is arranged between the longitudinal edges, and wherein at least one of the longitudinal edges of adjacent slats cooperating in the closed position has a seal.
  • MRA mechanical smoke extraction system
  • the US 2014/0008561 A1 discloses a generic Venetian blind flap wherein the pairs of beveled edges each have a pair of longitudinal edges and a cold seal is arranged on each longitudinal edge of a pair of longitudinal edges, the two seals of a pair of longitudinal edges being arranged next to one another and spaced apart from one another in the closed position.
  • louvre flaps In the closed position of the slats, louvre flaps are intended to close the flow cross-section and prevent the medium from flowing.
  • the slats In known louvre flaps, the slats have a rectangular cross-sectional shape. A lip seal protruding over the longitudinal edge is provided on one of the two longitudinal edges of each lamella.
  • each lip seal When swiveling the Slats from their open position to the closed position, each lip seal is folded when it comes into contact with the longitudinal edge of the adjacent slat.
  • the disadvantage is that a high torque is applied for reopening must be used, as the lip seals folded in one direction have to fold in the other direction when swiveling open. Otherwise, pressure can act on both sides of a multi-leaf damper. The side on which a print is acting is therefore not predictable. Due to the lip seals folded over in the closed position, the louvre withstands the tightness with one side of a significantly higher pressure than
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a louver that is in particular easier to open with at least the same tightness and also - if the louver is used as a fire protection component - can still be opened within a certain period of time after the fire.
  • the pivot axis is preferably also arranged centrally in relation to the thickness of the lamella in question.
  • the frame can be formed in one piece or, for example, consist of four frame elements arranged at right angles to one another.
  • the configuration according to the invention allows the slats to be closed homogeneously.
  • the torque required in particular for opening is smaller.
  • the drive can be dimensioned smaller. Due to the oblique orientation of the two surfaces forming a pair of inclined edges, if the seal is provided, for example, there is no folding over of the folded seal when the slats are swung open, since the surfaces in the first section are moved away from each other in a fairly straight line. Another advantage of the embodiment according to the invention is that the sealing (s) is (are) better protected by the oblique orientation of the two surfaces forming a pair of oblique edges in the closed position. This is particularly relevant when the multi-leaf damper is used as a fire protection component. If the multi-leaf damper is used as a fire protection component and at least one seal is designed as a warm seal, the oblique alignment after a fire also allows the slats to be opened within a certain period of time.
  • each slat is not rectangular, but is, for example, triangular or diamond-shaped
  • the pivot axis is arranged at the widest point of the slat in question.
  • the width of the slat then decreases in both directions.
  • the pivot axis lies in one of the three side edges.
  • the width then decreases continuously in the direction of the other two side edges. Since the lamella does not extend any further in the opposite direction, the width here is zero.
  • At least two lamellae can be connected, for example, via a common coupling element such that when the coupling element is displaced, the position of all the lamellae connected to one another via this coupling element can be changed equally.
  • the coupling element which is preferably arranged outside the frame, can act directly or indirectly on the pivot axes of the slats coupled to one another.
  • the frame can at least in one of the two areas, which in the closed position of the slats extend parallel to the upper and lower slats, have a stop surface which is oriented such that it is at least approximately parallel to the surface of the longitudinal edge of the adjacent lamella when it is in its closed position, forming a pair of inclined edges.
  • the stop surface can be part of a stop bar, for example, which is mounted on the inside of the frame.
  • the surface of the longitudinal edge of the adjacent lamella is at an angle ⁇ with respect to the orthogonal O, which is perpendicular to the plane E spanned by the lamella, which is between 10 ° and 60 °, preferably between 25 ° and 40 °, preferably at 30 ° lies, aligned.
  • the stop surface and the surface of the longitudinal edge of the adjacent lamella are preferably exactly parallel. However, a deviation of up to a maximum of 20 ° is also conceivable.
  • At least one stop surface may be part of the region which extends in the closed position of the slats parallel to the upper and lower slats.

  • the cold seal has thermal and physical stability up to the functional limit of 1,100 ° C and is ceramic-free.

  • the width of the seal can preferably correspond approximately to the thickness of the lamellae.

  • At least one seal can be arranged in a recess.
  • the seal preferably protrudes only with a partial area from the recess. But it is also quite possible that the seal is completely in the recess.

  • the seals touch in the closed position, provided that the gap is smaller than the extent to which both seals protrude from the respective lamella.
  • the seals are each arranged in a recess and preferably only protrude from their respective recess with a partial area, a seal designed as a warm seal can expand into the opposite recess in the event of a fire. A certain interlocking is achieved in this way. Due to the oblique alignment of the surfaces of each pair of bevelled edges, it is still possible to open the slats later, even with a foamed-on warm seal.
  • At least one seal can alternatively be arranged in a mutually offset direction in a direction orthogonal to both surfaces. With such a configuration, the seals do not touch in the closed position.
  • At least one seal is a warm seal that expands when exposed to heat, preferably in the form of a strip.
  • At least one warm seal can consist of a laminate-based foamer.
