Definitions

the invention relates to a flap, in particular a fire damper, with a shut-off slat that swivels in a housing or a pipe section is mounted and whose edges in the closed position on one side of the housing or seal arranged on the inside of the pipe a sealing material having cavities, in particular Foam, with the seal under the Effect of the actuating forces pivoting the shut-off lamella is deformable.
Such flaps are used, among other things. used as fire dampers. These must comply with the legal regulations also perform a smoke protection function, in particular should they have one during the smoldering phase Fire event prevent the spread of smoke.
the fire dampers with a circumferential Stop seal equipped for the shut-off lamella.
the shut-off plate On one in the middle of the housing or the pipe section arranged pivot shaft is stored, the shut-off lamella is divided into two sections divided by the swivel shaft. There is one seal each along the edge of a portion of the shut-off lamella provided, both seals offset from each other and viewed in the direction of flow on one Side of the pivot shaft are arranged. In the closed position is the shut-off lamella with one section on one side and with the other section on the other side of the respective seal.
the seals consist of a closed cell Foam. Through the closed cavities The foam ensures that the flowing Medium in the closed position not through the seal flowing. Because of the closed cell training the seal has a relative one hard and difficult to deform basic structure. on the other hand the seal must also have a sufficiently high elasticity have material-related bumps in the shut-off plate, such as B. with insulating lamella based on calcium silicate, or manufacturing tolerances of the Compensate the housing so that the shut-off plate in the Closed position, if necessary by a mechanical Lock is locked, the requirements for smoke tightness Fulfills. Due to the use of closed cell Foams, however, the elasticity is limited, because that's in the cavities of the foam air is compressed during deformation.
shut-off plate can be in the closed position not always optimally place on the shut-off lamella, so that Leaks can occur. You could think of that result from these conflicting requirements Problems with larger actuating forces, especially a larger one Closing moment to eliminate the shut-off slat. But in many applications this is technical as well not economically viable.
the object of the invention is therefore to provide a flap their seal with relatively low closing torques reliable seals.
the sealing material especially the foam, as an exit option for a medium in the cavities at least at least in the area facing the shut-off lamella partially open-celled to form openings is formed and that the seal at least in some areas such a flexible and gas impermeable coating, in particular a lamination, that in the Closed position of the shut-off lamella of the circumferential gap between housing or pipe section on the one hand and shut-off lamella on the other hand closed to interrupt the flow is.
the seal Through the open-cell cavities of the sealing material at least in the area of the shut-off lamella facing area when deforming the seal, the is caused by the closing moment of the butterfly valve the medium in the cavities of the seal without further pressed out of these through the openings, so that the seal has a high elasticity and itself adapts easily and optimally to the surface of the shut-off lamella.
the flexible and gas impermeable coating provided so that in the housing or the Pipe section flowing medium around the shut-off lamella around the gap can not happen.
the coating exhibit. In the closed position it lies with the Coated side on the shut-off lamella, see above that the housing or the pipe section interrupts flow can be locked.
At least the exposed areas from those facing away from the shut-off lamella, from the inside of the housing or the pipe section facing as well as from the housing or the pipe section facing sides of the seal the coating exhibit.
exposed areas understood such areas in the absence of coating a flow channel between the inflow and leave the outflow side of the flap.
the shutoff lamella can face the shutoff lamella Side of the seal in the rest position with the shut-off lamella open including an angle with the Housing or pipe section interior facing side of the Seal obliquely to the center of the housing or the pipe section be indicative. Because of the rejuvenation of the cross section of the seal in the edge area between the side facing the shut-off plate and the Housing or pipe section interior facing side can the seal turns slightly when the shut-off lamella is closed deform so that the seal rests against the shut-off lamella is improved. The seal hugs due to their higher flexibility, so that over a wide range of material-related bumps Shut-off slat and also manufacturing-related tolerances, z. B. Angular error of the housing or the pipe section be balanced.
the angle of the inside of the housing or pipe section Side and that facing the shut-off lamella Side can be between 40 ° and 60 °, preferably 50 °.
the seal on the housing or the pipe section is the seal on the housing or the pipe section.
the seal can with the opposite side of the shut-off plate on one Concern recording. This prevents the seal when closing the shut-off plate under certain circumstances can detach from the housing or pipe section.
the free end of the shot can be directed towards the shut-off plate must be angled.
the seal can then without further attachment in the between the Housing or the pipe section on the one hand and the angled Recording, on the other hand, used free space become.
the inclusion of one Sheet metal can exist.
the recording is a kind of lattice structure with recesses having, in such an embodiment the Seal then at least in the area of the recesses Recording an appropriate coating in the exposed Areas of the side facing away from the shut-off lamella or the inside of the housing or the pipe section facing side, unless that of the shut-off lamella Apply a coating to the side facing is.
the foam can be polyether urethane and / or contain polyester.
the seal can consist of a soft foam.
the coating can be used as a film, in particular as a polyurethane film, be trained.
the film preferably have a thickness 50 ⁇ m.
a seal for a flap, especially a fire damper, with a shut-off slat that swivels in a housing or a pipe section is mounted and whose edges in the closed position on the inside of the housing or seal arranged on the inside of the pipe a sealing material having cavities, in particular Foam, with the seal under the Effect of the actuating forces pivoting the shut-off lamella is deformable, is characterized in that the sealing material, especially the foam, as an exit option for one in the cavities Medium at least in the one facing the shut-off lamella Region at least partially open-celled to form Is formed openings and that the seal at least in some areas such a flexible and gas impermeable Has coating, in particular a lamination, that in the closed position of the shut-off lamella the rotating one Gap between housing or pipe section on the one hand and shut-off lamella on the other hand interrupting the flow is closed.
the fire damper shown has a housing 1 connection flanges 2 on both sides. In case 1 it can also be a pipe section. In the housing 1 is a shut-off lamella on a central pivot shaft 3 4 arranged. It is not shown that at the swivel shaft 3 can be driven by hand or by motor Attack control elements.
shut-off plate 4 is in the Played closed position at which its edges Seals 5 abut the housings on the inside 6 are arranged.
the housings on the inside 6 each have a free end 7, which in the direction of Stop slat 4 is angled.
the seals 5 consist of a foam that at least in the area facing the shutoff lamella 4 is at least partially open-celled. hereby ensures that when the shut-off lamella is closed 4 and thus when deforming the seal 5 in medium located in the cavities of the foam can emerge from these cavities, so that the seal 5 can be deformed without greater forces.
the side of the seal 5 facing the shut-off lamella 4 is in the rest position with the shut-off slat 4 open including an angle with the inside of the Housing 1 facing side obliquely to the center of the housing 1 is indicative. Therefore, the seal 5 in Contact area with the shut-off lamella 4 is very flexible and cuddly.
the housing 1 can have both round and rectangular cross sections exhibit. Also with rectangular cross sections a different arrangement of the pivot shaft 3 than that in Fig. 1 shown central arrangement, conceivable. It is z. B. quite possible that the pivot shaft 3 immediately adjoins a wall of a rectangular housing 1, in which case the seal 5 only on one Side of the shut-off plate 4 is arranged.
the housing 1 has in the area the pivot shaft 3 on a further seal 10 to the Area around the pivot shaft 3 in the closed position of the Sealing shut-off lamella 4.
This further seal 10 can consist of foam, for example here the foam is preferably closed-cell is.
