Definitions

  • the present invention relates to a fire damper, comprising an air flow duct, a damper blade which is provided in the air flow duct and can be rotated from an open position to a closed position and vice versa, and a strip of intumescent material which is able to expand under the effect of heat, in which this strip is designed to fill the space between the damper blade and the air flow duct after expansion and in the closed position of the damper blade, and in which the damper blade is provided with at least one protruding edge along its periphery.
  • such fire dampers are provided in order to prevent the propagation of a fire.
  • the damper blade With a first type, the damper blade will be brought to the closed position in the case of fire by means of a fusible link mechanism which activates a spring device at 72°C.
  • the damper blade With another type, the damper blade is brought to the closed position by means of a motorized device.
  • a cold seal seals the space between the damper blade and the air flow duct.
  • this cold seal cannot withstand the relatively high temperatures which occur during a fire. Therefore, such a fire damper is also provided with a strip of intumescent material, which is able to expand under the effect of heat.
  • This intumescent material has a relatively high density at room temperature, but expands when the temperature exceeds a certain threshold value. After expansion, the volume of this intumescent material increases by a multiple.
  • the intumescent material is provided in the fire damper in such a way that, after expansion, it fills up the space between the damper blade and the air flow duct and it takes on the role of the cold seal. Usually, this strip of intumescent material is provided in the air flow duct. In the fire damper from DE 295 07 931 U1 , this strip of intumescent material is provided along the periphery of the damper blade.
  • a protection is therefore provided which protects the intumescent material which is attached to the damper blade in such a manner that it cannot be sucked into the air duct on account of the air flow which is present therein.
  • a mechanical seal is produced in which the protection is pressed against the air flow duct by the intumescent material.
  • Providing protection is an expensive solution.
  • the fire resistance thereof is lower than when the intumescent material can completely fill the space between the damper blade and the air flow duct without being sucked out.
  • the fire damper from EP 0 595 729 A1 is provided with a liquid reservoir in a groove in the air flow duct in which, in the case of fire and in the closed position of the fire damper, the liquid is released and is absorbed by the absorbent damper blade in order to thus keep the damper blade cool.
  • the intumescent material can only be fitted on both sides of the passage opening of the liquid reservoir, with the result that in order to ensure good sealing, the damper blade has to be of a relatively wide design here too.
  • the construction of this fire damper is more complex in order to be able to ensure good cooling of the damper blade in case of fire. This is an expensive solution for the abovementioned problem.
  • the fire dampers from EP 0 816 774 A1 and DE 88 12 475 U1 comprise a damper blade which is provided with a protruding edge, with the shape of the air flow duct being of a complementary design thereto.
  • the complementary shape of the air flow duct results in a significant narrowing of the air flow duct. This leads to large pressure drops in this duct, which requires the associated ventilation device to be made larger as a result thereof. Overall, this is therefore also an expensive solution to the problem at hand.
  • this object is achieved by providing a fire damper comprising an air flow duct, a damper blade which is provided in the air flow duct and can be rotated from an open position to a closed position and vice versa, and a strip of intumescent material which is able to expand under the effect of heat, in which this strip is designed to fill the space between the damper blade and the air flow duct after expansion and in the closed position of the damper blade, in which the damper blade is provided with at least one protruding edge along its periphery and in which the strip of intumescent material is designed to be wider than the width of the damper blade.
  • this fire damper provides an improved locking of the damper blade compared to the prior art, as the damper blade rotates into its closed position and remains in the closed position, following which the intumescent material expands under the effect of the heat produced by the fire and fills the space between the damper blade and the air flow duct. That is to say that the intumescent material will now surround the damper blade at least partially by not only expanding against the edge of the damper blade but also against the protruding edge. This material is then not only blocked by the edge of the damper blade, but also by this protruding edge.
  • the damper blade and the strip of intumescent material no longer have to be made wider in order to achieve the same degree of fire resistance, which significantly reduces the material costs of the fire damper.
  • a groove is provided in the air flow duct of such a fire damper according to the present invention and surrounds the damper blade in its closed position along its periphery.
  • such a fire damper according to the present invention is furthermore provided along its periphery with at least two protruding edges which together delimit a groove.
  • this material In case of fire, in the closed position of the damper blade and after the intumescent material has expanded, this material will therefore also fill the groove in this damper blade and be secured therein. This material is then also secured in the groove in the air flow duct, in the groove in the damper blade and along the edge of the damper blade. In this manner, the intumescent material is then also secured in three ways, thus further increasing the fire resistance of the fire damper.
  • the strip of intumescent material is fitted in the groove in the damper blade.
  • this fire damper then comprises a second strip of intumescent material which is able to expand under the effect of heat, this strip being fitted in the groove in the air flow duct.
  • the strip of intumescent material which expands under the effect of heat is only fitted in the groove in the air flow duct.
  • the groove in the air flow duct is furthermore designed to be wider than the width of the damper blade.
  • fire dampers (1) In the case of wall passages in air ducts, fire dampers (1) according to the present invention are provided in order to prevent the propagation of a fire.
  • the fire dampers (1) illustrated in Figs. 1 to 5 comprise an air flow duct (2).
  • This air flow duct (2) preferably has a cross section corresponding to the cross section of the air duct in which the fire damper (1) is fitted. In the case of the known air ducts, this may be a round cross section or a rectangular cross section.
  • the air flow duct (2) is designed to be fireproof and may, for example, be made of galvanized steel. It may, for example, be bent from sheet steel (10).
  • These fire dampers (1) furthermore comprise a damper blade (3) which is fitted in the air flow duct (2) so that it can be rotated from an open position to a closed position and vice versa.
  • the damper blade (3) is also fireproof and may, for example, be moisture-proof.
  • the damper blade (3) is provided with at least one protruding edge (5) along its periphery.
  • the air flow duct (2) is provided with a groove (7) which, in its closed position, surrounds the damper blade (3) along its periphery.
  • these fire dampers (1) also comprise a strip of intumescent material (4) which is able to expand under the effect of heat, this strip (4) being designed to fill the space between the damper blade (3) and the air flow duct (2) after expansion and in the closed position of the damper blade (3).
  • the damper blade (3) of the fire damper (1) as illustrated in Fig. 1 is provided with two protruding edges (5) along its periphery which together delimit a groove (6).
  • the strip of intumescent material (4) of this fire damper (1) is fitted in the groove (7) in the air flow duct (2).
  • This groove (7) in the air flow duct (2) is designed to be wider than the width of the damper blade (3).
  • the strip of intumescent material (4) which is fitted in this groove (7) is also designed to be wider than the width of the damper blade (3).
  • Fig. 1 shows a detail of a first embodiment of a fire damper (1) according to the present invention in cross section.
  • This fire damper (1) is provided in a wall passage in a fixed wall (8), but could equally well be installed in a floor or a ceiling or a flexible wall.
  • the damper blade (3) from this embodiment of a fire damper (1) is provided with two protruding edges (5) which together form a groove (6).
  • the strip of intumescent material (4) of this fire damper (1) is fitted in the groove (7) of the air flow duct (2).
  • This groove (7) in the air flow duct (2) is designed to be wider than the width of the damper blade (3).
  • the strip of intumescent material (4) which is fitted in this groove (7) is also designed to be wider than the width of the damper blade (3).
  • this fire damper (1) is provided with a cold seal (9) for sealing the space between the damper blade (3) and the air flow duct (2) before the strip of intumescent material (4) expands.
  • this cold seal (9) is fitted in the air flow duct (2), but it could equally well be arranged on the edge of damper blade (3) along the periphery thereof.
  • Fig. 2 shows, in a diagrammatical sectional view, how an improved locking of the damper blade (3) compared to the prior art is achieved with a fire damper (1) as illustrated in Fig. 1 after expansion of the intumescent material (4) and in the closed position of the damper blade (3).
  • Figs. 3 to 5 furthermore show various alternative embodiments to illustrate the fact that the invention can be achieved by various embodiments, in each case resulting in an improved locking of the damper blade (3) after expansion of the intumescent material (4) compared to the prior art.
  • the damper blade (3) from the second embodiment of a fire damper (1) is provided with one protruding edge (5).
  • the strip of intumescent material (4) of this fire damper (1) is fitted in the groove (7) of the air flow duct (2).
