Definitions

  • the invention relates to a shut-off device for closing a flow channel for gaseous media, in particular fire damper, according to the preamble of claim 1, and an associated method according to claim 13
  • Devices in the form of fire dampers are used in flow channels in the form of large pipes, in particular in ventilation and exhaust ducts, which connect individual rooms or building sections with each other and can also be associated with, for example, a ventilation or air conditioning.
  • the fire damper should prevent an exchange of air or gaseous media between the interconnected by the flow channel rooms, so that heat and / or smoke from one room to a connected via the flow channel with this Expand or expand space.
  • the flap frame consists of a tubular sheet metal housing in which the flap wing is pivotally mounted.
  • the problem here is that in a fire, the flap frame is heated strongly and this heat from the flap frame on surrounding parts or areas, such as wall areas, can be transferred. This can damage the surrounding parts or areas or help propagate the fire into other rooms.
  • the invention is therefore an object of the invention to provide an improved shut-off device of the type mentioned above and an associated method for their preparation, which should be ensured that at a strong heating of a flow channel and / or located within the flow channel gaseous medium heat transfer prevented effectively by the shut-off device on surrounding parts or areas and beyond that in the simplest and most cost-effective manner can be produced.
  • shut-off device with the features of claim 1 and with respect to a method for their preparation according to the features of claim 13.
  • Advantageous embodiments of the invention are described in the further claims.
  • the flap frame consists of a refractory and heat-insulating, arranged transversely to the longitudinal direction of the flow channel plate element, wherein the flap wing has the same material properties as the flap frame.
  • the flap frame is made of a refractory and heat-insulating material, a heating of the flap frame and a heat transfer from the flow channel to the surrounding parts of the shut-off device or areas is prevented in a simple and effective manner. Damage to the surrounding parts or areas or fire spread to adjacent rooms can be effectively prevented.
  • the production of the flap frame from a plate element also allows a narrow, sturdy construction, which does not require a large installation space.
  • the flap wing can preferably have the same thickness and material properties as the flap frame, according to a preferred variant there is the possibility that the same or the same plates are used for producing both the flap frame and the flap wings, so that no different materials are stored and have to be edited.
  • the flap frame and the flap wings can be made of different thickness plate material.
  • This also offers the possibility that, for example, a flap made of a thicker plate material can also be used in a second flap frame made of a thinner plate material and vice versa.
  • the inventive advantage is achieved that both the cap frame and the flap wings are preferably cut from a sheet material, for example by means of laser or water jet, etc. or in any other suitable manner, which may be the cutting material with respect to the flap frame at the same time for the production the flap wing can be used.
  • the flap frame and flap wings made of the same plate material and / or made of a plate material with the same thickness can only be used together, but that the flap frame and the Flap wings can also be made of different plate material or of different plate material with the same or different material thickness and can be combined with each other regardless of the choice of material and the thickness of the plate material.
  • the formation of the flap frame as arranged transversely to the flow channel plate member has the advantage that in such a plate element, the storage of the flap wing on particularly simple and cost-effective manner, for example, only by introducing holes can be made.
  • the flap frame and the flap wing are made of a single plate, the flap wing consists of a plate cutout cut out of the plate to form the flow passage and the flap frame consists of the plate element surrounding the plate cutout.
  • the part of the plate cut out to form the flow passage is thus used as a flap wing.
  • the plate cutout already has a shape corresponding to the flow passage and appropriate size. As a result, the flap wing can be manufactured in a particularly simple and cost-effective manner.
  • the flap frame and the flap wing made of a lightweight concrete slab with heat-resistant additional fibers, in particular glass fibers.
  • a lightweight concrete slab with heat-resistant additional fibers in particular glass fibers.
  • Such a material has particularly favorable, refractory and heat-insulating properties.
  • the sealing arrangement has at least one seal which is attached to the flap wing and comprises a pivotable sealing section attached to the flap wing and a stationary sealing section attached to the flap frame which is separated from the pivotable sealing section in the area of the pivot axis.
  • Such a sealing arrangement offers the advantage that no frictional forces between the flap wing and the flap frame must be overcome if the flap wing is transferred from the open position to the closed position or from the closed position to the open position. There are therefore very small torques sufficient to cause the pivoting of the damper blade.
  • the drive motors used for pivoting can be made small, with low power and cost.
  • the sealing arrangement according to the invention can be used very variably and can be used in the most varied forms of flap wings or cross-sectional shapes of flow passages, for example in polygonal, in particular triangular, quadrangular or other polygonal, round, oval, elliptical cross-sectional shapes etc.
  • the pivotable sealing portion is disposed on a downstream side surface of the damper blade and the stationary seal portion on a downstream side surface of the damper frame.
  • This arrangement is particularly recommended when the shut-off device is provided only on one side with a corresponding seal.
  • a seal with a pivotable sealing portion and a stationary sealing portion is provided on both sides of the flap wing and the flap frame which are arranged one behind the other in the flow direction.
  • the pivot axis of the damper blade lies on its central axis, wherein the pivotable seal portion extends over a peripheral half of the damper blade, while the stationary seal portion extends over a peripheral half of the flow passage.
  • the pivot axis of the flap wing extends eccentrically to its central axis.
  • the pivotable and / or stationary sealing portion is attached by means of an adhesive, form-fitting and / or frictional connection on the flap wing or on the flap frame.
  • the pivotable sealing portion and / or stationary sealing portion consists of an at least predominantly planar sealing strip or lip of elastomeric, i. rubber elastic material.
  • planar sealing strips which have a flat, rectangular cross-sectional shape
  • seals having other cross-sectional shapes, for example arcuate cross-sectional shapes.
  • the seal can be shaped differently in its attachment areas than in that area which projects beyond the flap wing or the circumference of the flow channel.
  • the in the FIGS. 1 to 6 Shut-off device shown comprises a flap frame 1, which in the illustrated embodiment in the in the Figures 1 and 2 shown front view has a rectangular outer shape.
  • the flap frame 1 may have any other external shapes, for example, a circular, oval, elliptical, triangular or any polygonal shape.
  • the flap frame 1 consists of a plate member made of refractory and heat-insulating material.
  • the flap frame 1 consists of a lightweight concrete slab with heat-resistant additional fibers, in particular glass fibers.
  • the flap frame 1 thus preferably consists of a solid material.
  • the flap frame 1 is preferably made of a plate in which a recess of suitable size and shape, which forms a flow passage 6 for gaseous media, in particular for air, is introduced.
  • the flow passage 6 has a so-called superelliptic shape, ie, an elliptical shape somewhat approximated to a rectangle, such as in the EP 2 642 167 A2 described.
  • Other shapes for the recess and thus for the flow passage 6, for example, rectangular shapes, oval, elliptical, triangular or arbitrary polygonal shapes are possible.
  • the closed circumferential flap frame 1 has, as in particular FIG. 4 can be seen, an outer peripheral surface 2, a first side surface 3a, an opposite, parallel thereto second side surface 3b and an inner peripheral surface 5, which limits the flow passage 6 to the outside.
  • a flap wing 7 is pivotally mounted to open and close the flow passage 6.
  • the flap wing 7 consists in the same way as the flap frame 1 of a refractory and heat-insulating plate member and is conveniently made of the same plate as the flap frame 1.
  • flap frame 1 and flap wings 7 are made of a single plate, the flap wing 7 from that plate cutout which is cut out of the plate to form the flow passage 6.
  • the flap wing 7 has the same thickness in this embodiment and consists of the same material as the flap frame. 1
  • first of all a first flap frame 1 and a first flap wing 7 are made as described above from a first plate material having a first material properties and / or a first material thickness, preferably be cut out.
  • This cutting process can be performed, for example, by means of a laser or a water jet, etc.
  • at least one flap frame 1 and one flap wing 7 can also be produced from a second plate material, wherein this two plate element can consist of a material composition different from the first plate element and / or can have a different material thickness.
  • the flap frame 1 and the flap wing 7 consist of a refractory and a heat-insulating plate member, preferably at least in pairs in only one process sequence, ie in a process step of a sheet material ( Plate or plate element) are preferably cut out, with the same dimensions and multiple production of the flap frame 1 and the flap wing 7 these elements are interchangeable with each other.
  • the outer shape of the flap wing is adapted to the cross-sectional shape of the flow passage 6, that in the closed position of the flap wing 7, which in the FIGS. 1 to 3 is shown, only a relatively small circumferential gap 9 between a peripheral surface 8 of the damper blade 7 and the inner peripheral surface of the damper frame 1 is present.
  • the height of the gap is dependent on the thickness of the flap wing 7 and dimensioned so that the edges of the flap wing 7 do not come into contact with the inner circumferential surface 5 of the flap frame 1 when pivoting the flap wing 7 in or out of the closed position.
  • the flap wing 7 is pivotally mounted on the flap frame 1 by means of bilateral, aligned bearing pins 10 which define a pivot axis 11.
  • the pivot axis 11 is located on the longitudinal center axis of the flap wing 7, which is arranged horizontally in the embodiment shown.
  • the pivot axis 11 may also be arranged differently and, for example, lie on the vertical center axis 12.
  • two separate bearing pins 10 are provided in the embodiment shown, which extend only over a relatively short length in the flap wing 7 inside.
  • At least one of the bearing pins 10 is also used as a drive shaft to the flap wing 7 between its closed position and its open position move.
  • this bearing pin 10 is rotatably connected on the one hand with the flap wing 7 and on the other hand with a transmission, not shown, with which cooperates, for example, a drive motor or which can be manually operated.
  • the shut-off device has a seal arrangement which comprises a two-part seal 13a, 13b which surrounds on both sides of the shut-off device and which is closed in the closed position of the damper blade 7 along the circumferential gap 9.
  • the seal 13 b is the same as the seal 13 a formed, but with respect to the pivot axis 11 point-symmetrically attached to the flap wing 7 and the flap frame 1. In the following, therefore, only the seal 13a will be described in more detail.
  • the seal 13a includes a pivotable seal portion 14a attached to the flap wing 7 and a stationary seal portion 15a fixed to the flap frame 1.
  • the pivotable sealing portion 14a extends only along one of the two flap wing peripheral halves, which are separated by the pivot axis 11 from each other. In the embodiment shown, the pivotable sealing portion 14 a extends only along that peripheral portion of the flap wing 7, which is located below the pivot axis 11. Furthermore, the pivotable sealing portion 14a of an at least predominantly planar sealing strip made of elastomeric, ie, rubber-elastic material, for example, rubber or may be a rubbery material.

Furthermore, the pivotable sealing portion 14a projects outwardly beyond the outer peripheral surface 8 of the damper blade 7, that in the closed position, in FIG. 3 is shown, the gap 9 is bridged and the pivotable sealing portion 14 a can create tightly against the side surface 3 a of the flap frame 1. In the closed position, therefore, the pivotable sealing portion 14 a partially overlaps the side surface 3 a of the flap frame 1 in that flap frame half, which is arranged below the pivot axis 11.
  • the pivotable sealing portion 14a thus has the shape of a U, the free legs extend to the pivot axis 11.
  • the stationary seal portion 15 a is fixed to the inner edge of the flap frame 1 and formed in the same manner as the pivotable seal portion 14 a, but arranged axisymmetric to the pivot axis 11 exclusively in the upper half of the flap frame 1.

  • the stationary sealing portion 15a protrudes from the flap frame 1 so far inwards into the flow passage 6 that it bridges the circumferential gap 9 when the flap wing 7 is closed, whereby the side surface 16a of the flap wing 7 can be brought into tight contact with the stationary sealing portion 15a in its edge region ,
  • the pivotable sealing portion 14a and the stationary sealing portion 15a both of which are arranged on the same side of the shut-off device, complement each other in the closed position to a closed circumferential seal 13a, which lies in a plane, on the flap frame 1 and the flap wing 7 abuts and the circumferential gap 9 bridged.
  • shut-off device is arranged in such a ventilation or exhaust duct, not shown, that the gaseous medium in the FIGS. 3 to 5 flows from left to right, thus the pivotable sealing portion 14a is additionally pressed against the flap frame 1 with the flap wing 7 by the flow pressure, while the stationary sealing portion 15a by the flow pressure in addition against the flap wing 7 is pressed. This assists the sealing effect of the seal 13a.
  • the seal 13b arranged on the other side of the shut-off device is the same as the seal 13a, but is arranged point-symmetrically with respect to the pivot axis 11. This means that the pivotable seal portion 14b is fixed to the upper half of the flapper blade 7 on the side surface 16b, while the stationary seal portion 15b in the lower half of the flapper frame 1 is fixed to the side surface 3b.
  • the bearing pins 10 are mounted in the flap frame 1 in aligned holes, which are centrally placed on both sides of the flap frame 1. With these holes opposite blind holes of the flap wing 7, in which the bearing pins 10 extend into it.
