Definitions

  • the invention relates to a fire damper with, for example, a round or angular housing and with a shut-off flap blade, which is mounted therein, in particular in the center of the housing cross-section, between an open position and a closed position about an axis of rotation and which moves from its closed position into its open position against the restoring force of a spring element is pivotable, wherein a retaining element is provided for fixing the butterfly valve blade in its open position, which in the open position of the butterfly valve blade interacts with a retaining area of a thermally releasable release device, the retaining area being releasable from its retaining position by heat or the like and automatically displaced into its release position, whereby the interaction of the holding element and the holding area located in the holding position holds the butterfly valve blade in its open position and after it has been triggered en the triggering device and thus after displacement of the holding area from its holding position into its release position, the displacement of the butterfly valve leaf is effected by the restoring force of the spring element into its closed position
  • a manually operated actuating lever is provided on the outside of the housing to move the shut-off flap leaf of the fire dampers described above from its closed position to its open position against the restoring force of the spring element.
  • the actuating lever acts with the holding area of the release device, which comprises a fusible link together.
  • the holding area is shifted from its holding position to its release position. As a result, the butterfly valve blade is suddenly shifted into its closed position by the restoring force of the spring element.
  • the object of the invention is to avoid the aforementioned disadvantages and to provide a fire protection flap whose butterfly valve blade can also be moved slowly and in a controlled manner from its open position into its closed position, for example.
  • the fire damper has a drive that is directly or indirectly connected to the damper blade and is arranged on the outside of the housing to move the butterfly valve blade between its closed position and its open position and vice versa, and that for the remotely controllable release of the fixation between the Holding area of the release device and the holding element for the subsequent displacement of the butterfly valve leaf from its open position into its closed position, brought about by the drive or the spring element either the area of the holding element that interacts with the holding area of the triggering device or the holding area of the triggering device that interacts with the holding element can be displaced by means of a remotely controllable release device, the speed of displacement of the butterfly valve blade from its open position into its closed position being determinable by the drive.
  • the torque generated by the drive acting on the butterfly valve blade is greater than the restoring force generated by the spring element.
  • the fire damper can have a continuous shaft, the drive being pushed onto one of the two ends of the shaft.
  • two stub shafts can also be provided, the drive being slipped onto one of the two stub shafts.
  • the drive acts directly on the butterfly valve blade.
  • the drive is indirectly connected to the butterfly valve blade via a linkage, which is preferably arranged in the housing.
  • the configuration according to the invention allows, for example, a routine check of the functionality of the fire damper remotely, for example by the building control system.
  • Remotely controllable means that the corresponding relocation cannot be initiated manually on the fire damper itself, but from a remote location, for example from another room.
  • a functional test of all fire dampers installed in a building can be carried out via the building management system, without the person checking having to gain access to each fire damper as was previously the case in order to then be able to manually relocate it.
  • the position of the butterfly valve leaf can be changed as desired, for example by the building management system, ie the butterfly valve leaf can be moved slowly and in a controlled manner from its open position to its closed position and back. In addition to the open position and the closed position, any intermediate position of the butterfly valve blade can also be approached.
  • the drive is selected so that the torque generated by the drive is greater than the restoring force of the spring element acting on the butterfly valve leaf.
  • the butterfly valve blade can be moved slowly and in a controlled manner into its open position and equally slowly and in a controlled manner by the drive back into its closed position.
  • the drive can be used to open and, if necessary, also to close the butterfly valve blade, while the thermal release device causes sudden displacement in the event of a fire.
  • the remotely controllable release device enables the remote-controlled opening and closing of the butterfly valve blade.
  • the drive and the remotely controllable release device can also be easily retrofitted to a known manually operated fire damper, so that a known manually operated fire damper can be converted to the embodiment according to the invention. Retrofitting is easy, since the manually operated actuating lever, for example, only has to be replaced by the drive and the remotely controllable release device has to be installed.
  • the butterfly valve blade Due to the intrinsic safety of the mechanics, the butterfly valve blade remains in its open position even when the drive is de-energized. This proves to be an advantage, for example in the construction phase of a building project, compared to solutions known in the prior art. During this time, there is sometimes a desire to open fire dampers in order to be able to ventilate the building. The existing thermal release device is nevertheless ensures that the butterfly valve blade is moved into its closed position in the event of a fire.
  • the release device can be an electrically operating, a hydraulically operating or a pneumatically operating device.
  • the release device can cause a displacement in both directions.
  • the release device can be designed as an electromagnet.
  • the area of the holding element that interacts with the holding area of the release device can be designed as a locking bolt.
  • the locking bar can be rigidly connected to the retaining element.
  • the function of a fire damper with this design is as follows: For the purpose of fixing the butterfly valve blade in its open position, when the drive is rotated in the untwisting direction, the sliding of the locking bar along the guide section causes an increasing displacement of the labyrinth against the spring force generated by the spring and thus the distance between the labyrinth and the housing is increased. After a further displacement of the locking bolt in the untwisting direction, after the locking bolt has slid completely along the guide section, the labyrinth and thus also the retaining area are moved by the spring in the direction of the housing, making contact between the locking bolt and the retaining area to fix the butterfly valve leaf in its Relocated open position.
  • the locking bolt can first be displaced further in the untwisting direction by the drive until the locking bolt is no longer in contact with the contact surface, and the labyrinth is then moved further in the direction of the housing by the spring, so that the locking bolt is in the return and the butterfly valve blade can be moved into its closed position after changing the direction of rotation of the drive.
  • the locking bolt Only one drive is required. Due to the interaction of the locking bolt and the labyrinth, the butterfly valve blade can be both closed and opened by means of the drive.
  • a freewheeling device which has two transmission elements that are positively connected to one another and enabling freewheeling, the freewheeling device being designed in such a way that when the butterfly valve blade is suddenly displaced by the spring element after the release device has been released from its open position its closed position the drive is decoupled.
  • the freewheel device represents a positive coupling with a freewheel, which is arranged between the drive or a possibly provided gear on the one hand and the butterfly valve blade on the other hand.
  • the length of the freewheel produced by the freewheel device corresponds approximately to or equal to a quarter turn, i. H. the displacement path of the butterfly valve blade from its open position to its closed position.
  • the freewheel device ensures that in the event of a fire, when the butterfly valve blade is suddenly shifted by the spring element from its open position to its closed position after the release device has been triggered, the spring element does not have to move the drive and possibly the gear arranged between the butterfly valve blade and the drive. Rather, the drive and possibly also the transmission is (are) decoupled preferably over the entire displacement path from the open position to the closed position.
  • one transmission element can comprise a receiving area having a circumferential wall, with an elongated hole extending approximately over a quarter of the circumference of the wall being provided in the wall, and the other transmission element comprising a transmission section projecting into the receiving area with a laterally protruding pin , wherein the pin protrudes into the elongated hole and the receiving area is dimensioned such that at least one rotation of the transmission section over the length of the elongated hole is possible in the receiving area.
  • the freewheel device can be designed as a claw clutch, with one transmission element being a driver disk with at least one, preferably two or more evenly over the circumference of the one transmission element arranged in the direction of the other transmission element comprises a claw and the other transmission element comprises a drive plate with at least one, preferably two or more evenly arranged over the circumference of the other transmission element, pointing in the direction of the one transmission element, the claw (n ) of the two driver disks interlock. If each drive plate has two claws, each drive plate has two spaces. There is a space between two adjacent claws of a drive plate. A corresponding claw of the other drive plate engages in an intermediate space.
  • the width of the claws is dimensioned in relation to the space formed in each case in such a way that a freewheel between the two driver disks is generated, which corresponds approximately to or equal to a quarter turn of the butterfly valve blade. This intervention enables torque transmission by turning.
  • a claw coupling is also a form-fit coupling.
  • the release device can be attached to the holding element or integrated into the holding element. In such a configuration, the release device is part of the holding element. If the area of the holding element that interacts with the holding area of the release device is designed as a locking bolt, the release device actuates the locking bolt.
  • the drive can be designed as an electrically operating drive. Of course, other configurations are also possible. For example, it can also be a pneumatically or hydraulically operating drive.
  • the drive can be designed as an idling motor, the direction of displacement being such that the butterfly valve blade can be moved from its closed position into its open position by means of the drive.
  • An idle motor is a drive that only allows displacement in one direction of rotation. At least partial decoupling takes place in the opposite direction of rotation.
