Definitions

the invention relates to a flap, in particular a fire damper, with a shut-off slat that can be swiveled in an angular, in particular square housing and its edges in the closed position over a Seal are sealed to the housing, the Seal under the action of the shut-off lamella pivoting Actuating forces is deformable.
Such flaps are used, among other things. used as fire dampers. You must comply with the legal requirements also perform a smoke protection function, in particular should they have one during the smoldering phase Fire event prevent the spread of smoke.
shut-off lamella there is a seal along the edge of a section the shut-off lamella provided, both seals offset to each other and seen in the direction of flow are arranged on each side of the pivot shaft. In the closed position, the shut-off slat is therefore also with one section on one side and with the other Section on the other side of the respective stop seal on.
a disadvantage is that in the case protruding receptacle for the stop seal of the flow cross section considerably reduced and also the flow behavior negatively affected in the area of the shut-off lamella becomes. This disadvantage is special with housings pronounced with small cross-sectional dimensions.
the object of the invention is therefore a flap for angular Specify housing that is less strong in the open position influences the flow behavior.
a lip seal can be provided for sealing.
the lip seal can fall, for example, on the shut-off lamella be glued or screwed on. In the assembled Condition, the lip seal protrudes so far over the Extent of the shutoff lamella out that the between shutoff lamella and housing remaining gap in the The shut-off lamella is fully sealed becomes.
the lip seal When using the lip seal in a square To this extent, the lip seal is in the open position the shut-off lamella only on the two side walls of the housing in which the swivel shaft is mounted is on. The lip seal is only after it has been closed in contact with the housing on all sides. Because the lip seal protrudes more than the circumference of the shut-off lamella than the thickness of the seal to be sealed between the housing and the shut-off lamella Gap, it is deformed and sealed so the gap sure.
the rounded corner areas of the housing by an approximately quarter-circular design, with its concave surface the center of the Housing facing molded parts can be formed.
These molded parts can for example by gluing in the square Housing can be fixed. It is obvious that the Use the molded parts in a square housing are quarter-circular and a total of four Molded parts in the area of the shut-off lamella in the four corner areas of the housing must be provided.
the molded parts can be part of an interior adapted to the housing and insertable into the housing and formed there fixable frame construction his.
the molded parts fixed to the frame structure outside the housing become. Subsequently, it is then with the Molded frame construction in the housing inserted and fixed there.
the housing can be made of attachable to each other by means of fastening means and side walls can be fixed against each other, each Side wall formed along its longitudinal edges in this way is that in the assembled state of the side walls in the inner There are roundings in each corner area.
the housing can for example four side walls or two L-shaped trained side walls to be built. As for the arrangement the rounding concerns, so that in the housing intend to round off only one, for example Long edge of a side wall may be provided so that after assembly the intended roundings in each interior Corner area of the housing are provided.
At least one rounded corner area can be made of metal or made of a fire-resistant material, especially chamotte, consist. But there are also other materials conceivable.
a preferably circumferential groove for receiving the lip seal can be provided. With shut-off slats large dimensions, it can be recommended that the lip seal, for example by screws is fixed in the groove.
the lip seal can be made of a synthetic rubber, preferably neoprene.
the housing can be in opposite the shut-off lamella in the closed position area to be sealed a perforation, in particular a from several rows of circumferentially against each other offset slots existing perforation, and on the inside at least in the area of the perforation on the Housing an intumescent material may be provided.
a perforation in particular a from several rows of circumferentially against each other offset slots existing perforation, and on the inside at least in the area of the perforation on the Housing an intumescent material may be provided.
an intumescent material may be provided.
the intumescent occurs Material through the perforation and seals the outside of the housing from a masonry.
the area having the perforation is preferably to increase the stability of two rotating, preferably inward beads, limited.
the housing is also a pipe section can be trained.
the flap shown has a housing 1 with both sides Connection flanges 2 on.
Connection flanges 2 on.
In the case shown 1 can also be a pipe section.
shut-off lamella 4 In the housing 1 is on a centrally arranged pivot shaft 3 a shut-off lamella 4 is pivotally mounted.
the shut-off slat 4 can be done manually using a lever 5 from the in 1 and 2 shown in the open position in Fig. 3 shown closed position are moved. Not it is shown that 3 additional on the pivot shaft Actuators can attack, for example cause automatic closing in an emergency.
a lip seal 8 also encircling groove 7 provided that over the edge 6 and the circumference of the shut-off lamella 4 protrudes on all sides.
the lip seal 8 protrudes further over the edge 6 of the shut-off lamella 4 further than that between the shut-off lamella 4 and the housing 1 circumferential gap to be sealed is wide.
Air conditioning system are in the connecting flanges 2 Bores 12 provided through the fastener, not shown to grab.
FIG. 4 shows an embodiment, in which the housing 1 out of a total of four Sidewalls is built, for reasons of clarity only two immediately adjacent side walls 15, 16 are shown.
the longitudinal edges of the adjacent side walls 15, 16 are bent so that they are assembled State a roughly quarter-circle, with its concave surface the center of the case 1 facing surface result.
the Side walls 15, 16 legs pointing outwards at the end 17, 18, which touch in the assembled state. through a screw 19, the side walls 15, 16 against each other fixed.
connection flanges 2 are mounted on the front, for example are welded on.
FIG. 5 shows a top view of a lip seal 8.
the roundings in the corner areas are clearly recognizable the outer edge, while that facing the shut-off lamella 4 Inner edge bevelled in the area of the rounded corners is.
the groove 7 of the shutoff lamella 4 has corresponding Bevels on. This ensures that the lip seal 8 in the groove 7 of the shut-off lamella 4 aligns itself.
molded parts 11 also used as a retrofit in a square housing 1 Molded parts can be formed, in this If the molded parts 11, for example, on the inside of the Housing 1 are glued or screwed.
the molded parts 11 can z. B. made of metal or a refractory or -resistant material, such as. B. chamotte, consist.
the invention has the housing 1 only in the area of Barrier blade 4 rounded corner areas. But it is also quite possible that the housing 1 over the complete Has corresponding rounded corner areas in length.
