Definitions

  • the present invention relates to a Fire protection device for a ventilation pipe, especially for the exhaust port of a ventilation unit or a wall or ceiling shut-off device being the wall a nozzle is lined with a fire protection compound, which foams at elevated temperature (Intumescent foam).
  • the fire protection device thus serves either generally as a wall or ceiling barrier for ventilation pipe systems or to shut off the Exhaust nozzle of a ventilation device.
  • This use case is particularly suitable for such ventilation devices that used in a branch line of a ventilation system be used, for example, for interior rooms in Apartment buildings, for example small kitchens, toilets, bathrooms Find use.
  • the outlet port is on the Discharge side (pressure side) of the ventilation device.
  • This Venting devices are usually relatively flat, so that they are in a comparatively thin wall of the ventilating room can be accommodated.
  • Of the Air outlet is either parallel to the axis of the Fan or arranged at right angles to this.
  • Venting devices of the type mentioned are generally with a so-called check valve. This comes to Use when on the exhaust side of the venting device Negative pressure develops and should then close. It is also known for the blow-out of such Ventilation devices to provide fire protection devices. However, the problem with those from the prior art known fire protection compounds in the exhaust port can be introduced that these intumescent foams usually start at a higher temperature froth up and close the outlet port. After The fire protection regulations may require a Closure of the exhaust port in the event of a fire to reach a lower temperature between the Room temperature and the response temperature of the Intumescent foam.
  • the check valve is on the The exhaust side of the vent device is open and it is possible that the source of the fire or fumes through this open outlet pipe into the one to be vented Enter space and spread out further.
  • the vent valve's check valve would only open close if the venting device were switched off. If but this runs in the event of a fire is a moment of danger given.
  • the object of the present invention is a Fire protection device for a ventilation pipe, e.g. For the exhaust port of a ventilation device or a wall or To create a ceiling barrier of the type mentioned, that responds at a lower temperature, for example on the order of about 70 ° C and a Close the non-return valve even if it is running Fan causes.
  • a fire protection device provides the solution to this task for a ventilation pipe, especially for the Exhaust nozzle of the ventilation device or a wall or Ceiling shut-off device of the type mentioned with the characteristic features of the main claim.
  • the fire protection device ensures use for the exhaust port of a ventilation device not just a response at a relatively low level Temperatures below the foaming temperature of the Fire protection compound itself but it also ensures that the exhaust port is closed in particular smoke-tight and thus the fire protection regulations are satisfied is done.
  • a closure device which is open when not in use and parallel to the axis of the Nozzle is arranged and it is a trigger device provided that is designed so that it at a predetermined higher temperature triggers below the Foaming temperature of the fire protection compound is at this release process the previously in its open position held closure flap is released and through a pivoting movement automatically into a closed position moves in which it closes the cross section of the nozzle.
  • Said closure device can either be a Closing flap and can be used as a trigger device Use fusible link.
  • Said closure device can also be the closure device sub-segment of the Be fire protection compound that when the Tripping device in the direction of the tube axis of the Ausblasstutens tilts and thereby the inner cross section of the Exhaust nozzle closes.

  • Closure device an articulated in the outlet of the Venting device (or in the nozzle of the wall or Ceiling shut-off device) arranged sub-segment of the Fire protection compound, which in when the triggering device is triggered Direction on the pipe axis of the outlet nozzle tilts and this closes the inner cross-section of the outlet nozzle.
  • This variant can e.g. so that the The majority of the fire protection compound is also solid in the mentioned elevated temperature (at which the Closure device still responds to the fire protection compound not foaming) and the articulated sub-segment can, for example, based on the scope of the Fire protection compound make up a quarter segment or less.
  • the function of foaming the entire fire protection compound at an even higher temperature to It is, of course, a matter of course to close the exhaust connection flame-tight receive.
  • the triggering device can be designed, for example, that the remaining piece is wedge-shaped and in this one Provides hole, for example, a compression spring record that responds at an elevated temperature.
  • This Compression spring can be made of a memory metal, for example be trained and then reach a certain one Extend temperature. The compression spring then engages under one Inclined surface of the articulated segment of the Fire protection compound on the sloping surface of the wedge-shaped Rest piece and then the sub-segment folds in, because it is pushed up by the spring and then closes the inner cross-section of the outlet connector is smoke-tight. Since there the remaining wedge-shaped piece remains there Part of the cross-section of the outlet connection is smoke-tight locked. Would you be without this wedge-shaped remnant could work there after folding the articulated Part of the fire protection compound is a passage for smoke arise.
