Definitions

  • the invention relates to a fire damper with a housing and with a, in particular centrally on the housing cross section, between an open position and a closed position about a pivot axis pivotally mounted shut-off valve, wherein for pivoting, ie for clamping, the shut-off valve from its closed position against the restoring force in its open position a directly or indirectly cooperating with the shut-off valve and arranged on the outside of the housing to an associated rotary axis rotatable actuating handle is provided, wherein at least one stop is provided, against which the butterfly valve in its open position directly or indirectly abuts, and wherein the fire damper a triggering device, which can be brought into a fixing position and by heat or the like, for example in case of fire, triggered and thus automatically displaced into a release position, and wherein the Betrelincysgrif f and thus the shut-off valve connected to it in the open position against a restoring force by means of the release device located in its fixing position in a position corresponding to the open position of
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a fire damper, wherein in the open position, the butterfly valve is aligned as parallel as possible to the flow direction.
  • the embodiment of the invention allows the stop can already be factory mounted so at the desired location on the inside of the housing, that the butterfly valve is aligned in the applied state in each case parallel to the flow direction. This is possible by the material of the actuating handle or by an additional element or by an intermediate element arranged between the actuating handle and the axis of rotation.
  • the restoring force must first be overcome upon rotation of the actuating handle until the butterfly valve comes into contact with the stop.
  • the butterfly valve for example, in manufacturing tolerances, as they may occur, for example, consisting of several components transmission mechanisms is aligned in the open position to a parallel to the flow direction and on the other rests against the stop.
  • the actuating handle may be connected with a positive connection with the axis of rotation, wherein the form-fitting has game and the use of this game is not yet released by the additional force.
  • the Rotary axis have a quadrangular cross-section.
  • the actuating handle preferably has a recess with four corners, wherein each edge portion of the recess between the center and a corner is widened, so that the actuating handle against the axis of rotation game.
  • an intermediate element may for example be provided a slip clutch.
  • a, preferably the operating handle in the region of the axis of rotation from the outside overlapping, rotatably connected to the axis of rotation element may be provided, the at least one, at least one bearing surface forming, side part having.
  • the bearing surface serves as a bearing for a spring.
  • Each fire damper has a housing 1 with a centered on the housing cross-section, between a Open position and a closed position about a pivot axis 23 around pivotally mounted shut-off valve 2.
  • an actuating handle 4 is provided on the outside of the housing 1, which is rotatably mounted about a rotation axis 5.
  • the actuating handle 4 has a rearwardly projecting projection 6 in the area of its free end on the rear side.
  • the spiral spring 3 is guided around the axis of rotation 5 on the outside in the exemplary embodiment shown.
  • the pivot axis 23 of the butterfly valve 2 and the axis of rotation 5 of the operating handle 4 are separate components.
  • the butterfly valve 2 is connected via a non-illustrated, arranged in the interior of the housing 1 transmission mechanism 24 with the axis of rotation 5.
  • the transmission mechanism 24 has a rotary bearing 25 provided on the shut-off flap 2 and a coupling rod 26 connected directly or indirectly to the rotation axis 5.
  • a stop 7 is provided, on which the butterfly valve 2 rests directly in its open position.
  • the stopper 7 is disposed respectively on the inside of the housing 1.
  • the stopper 7 is arranged on the shut-off valve 2 or on the transmission mechanism 24, for example on the side of the coupling rod 26 facing the shut-off flap 2.
  • the butterfly valve 2 and the coupling rod 26 are aligned approximately parallel, wherein the stop 7 prevents further pivoting of the butterfly valve 2 beyond the open position addition.
  • the triggering device 8 comprises a arranged in the region of the housing recess 9, in which a bolt, not shown, is guided.
  • the bolt In the open position, i. In case of fire, the bolt is automatically displaced by a spring to some extent from the recess 9 to the outside in the fixing position of the operating handle 4, whereby the projection 6 of the actuating handle 4 is pressed out of the recess 9 and the butterfly valve 2 and thus also the operating handle 4 by the restoring force generated by the coil spring 3 in the closed position, ie in the release position of the operating handle 4, is pivoted.
  • a blocking element 10 in the form of a bolted sheet is provided on the outside of the housing 1.
  • the free end is arranged at a distance from the housing 1.
  • the blocking element 10 after Fig. 1e still has a slot 11. In the closed position of the butterfly valve 2 protrudes the projection 6 of the operating handle 4 in the embodiment Fig. 1 in the slot 11 inside.
  • an operating handle 4 in the region of the axis of rotation 5 from the outside overlapping, rotatably connected to the axis of rotation 5 connected element 16 is provided, which has two mutually spaced side parts 17.
  • Each side member 17 forms two bearing surfaces 18.
  • the other end of each spring 15 acts laterally on the corresponding abutment 19 of the actuating handle 4.
  • each abutment 19 is provided for fixing the corresponding spring 15 in a recess 20 of the actuating handle 4.
  • the butterfly valve 2 In the in the Fig. 1b to 1g shown position, the butterfly valve 2 is already in its open position, since it already has contact with the stopper 7. However, the projection 6 of the actuating handle 4 can not yet interact with the recess 9 of the triggering device 8. In order to overcome the remaining remaining distance, the operating handle 4 is further in the same direction of rotation (arrow 13), overcoming the additional force exerted by the two springs 15 is turned. This additional force is greater than the force that is applied for a displacement of the butterfly valve 2 from its closed position to come into contact with the butterfly valve 2 with the stopper 7.
  • the rotation axis 5 has a quadrangular cross section.
  • a recess is also provided with four corners.
  • each edge portion 21 of the recess between the center and a corner is expanded by the angle ⁇ , so that the operating handle 4 with respect to the axis of rotation has 5 game.
  • FIG. 2a to 2g a second embodiment of an intermediate element 14 is shown.
  • the intermediate element 14 is rotatably mounted on the axis of rotation 5 and has two spaced-apart resiliently formed regions 22, each spring-trained Region 22 acts laterally on the actuating handle 4 arranged therebetween.
  • the operation is identical as in the embodiment of Fig. 1 ,
  • a third embodiment is shown, which has the same operation.
  • a torsion-enabling element which consists for example of plastic provided, one end of which is non-rotatably connected to the rotation axis 5 and the other end non-rotatably connected to the actuating handle 4.
  • the further structural design for example with respect to the realization of the game between the operating handle 4 and the axis of rotation 5, is substantially the same as in the embodiments described above.
  • a fourth embodiment is shown.
  • the intermediate element 14 again rotationally fixed relative to the axis of rotation 5 is arranged.
  • the intermediate element 14 is made of plastic, for example. It has a resiliently formed region 22, which acts laterally on the actuating handle 4.
  • the actuating handle 4 is in turn so connected to the axis of rotation 5 in a positive connection that the form-fitting has game and the use of this game is released by the additional force exerted by the resilient portion 22.
