Definitions

  • the invention relates to a shut-off device for use in an air duct of a ventilation system or a mechanical smoke extraction system, wherein the shut-off device comprises a housing, preferably having a square cross-section, through which a gaseous medium flows, with a housing wall and a damper blade pivotably mounted in the housing about a pivot axis.
  • shut-off devices In their closed position, shut-off devices are intended to close the flow cross-section of the air duct and prevent the gaseous medium from flowing. If the shut-off device is designed as a fire damper, the damper blade is made of calcium silicate. Although corresponding shut-off devices can be used in air ducts for the ventilation of living or working spaces, for example, they cannot be used in atmospheres that have a damaging and/or corrosive effect on the shut-off device due to chemical reactions, either planned or unplanned, as the areas of the shut-off device that are in contact with the medium flowing in the housing are attacked by a chemically aggressive gaseous medium.
  • the object of the invention is to avoid the above-mentioned disadvantages and to provide a shut-off device which also works in atmospheres which are planned or can be used unscheduled due to chemical reactions which have a damaging effect on the shut-off device and/or cause corrosion of metallic and non-metallic materials.
  • shut-off device for use of the shut-off device in connection with a chemically aggressive gaseous medium, at least all areas of the shut-off device that are in contact with the medium flowing in the housing are designed to be resistant to damaging chemical reactions with this medium or due to this medium, wherein the resistance is formed by a coating applied to the areas that come into contact with the flowing medium.
  • the pivot axis can be formed by a fixed axis or by a shaft that is rotationally fixed relative to the flap blade.
  • the axis or the shaft can be Teflon-coated, for example.
  • the shut-off device according to the invention therefore has no metallic surfaces, at least in the areas that are in contact with the medium flowing in the housing.
  • a chemically aggressive gaseous medium is understood to mean, for example, contaminated and aggressive exhaust air from laboratories and laboratory fume hoods, from the chemical industry, from electroplating or from the automotive industry.
  • This exhaust air can be chemically contaminated with a wide variety of substances, some of which are very aggressive, such as acids or bases. However, it can also be exhaust air from commercial kitchens.
  • a coating applied to the areas that come into contact with the flowing medium prevents the areas that come into contact with the flowing medium from being attacked by the chemically aggressive gaseous medium. All areas of the shut-off device that are in contact with the medium flowing in the housing are thus resistant to the atmosphere prevailing in the shut-off device. As a result of the resistance, a chemical reaction initiated by the chemically aggressive gaseous medium is prevented, or at least reduced to a minimum, so that the shut-off device according to the invention, which is for example a fire damper, can be used safely for just as long as a conventional shut-off device designed as a fire damper in an air duct for the ventilation of, for example, living or working spaces.
  • all areas refers to the areas/components of the shut-off device that come into contact with the flowing medium and that are relevant to the function of the shut-off device. These are, for example, the inside of the housing wall, the flap blade, the bearing or the like. However, it can also be the outside(s) of the shut-off device, which is (are) used in a laboratory room, for example.
  • the flap can be made of calcium silicate, for example a calcium silicate plate, or of metal. All areas of the flap surface that come into contact with the flowing medium are provided with the coating according to the invention.
  • the applied coating can also provide additional protection against mechanical stress.
  • the flowing medium can contain particles that have an abrasive effect on areas of the shut-off device located inside the housing.
  • the coating applied to the areas that come into contact with the flowing medium means that the shut-off device can also be used in atmospheres with a high particle content, for example.
  • a two-component or multi-component epoxy resin coating can be used as the coating.
  • This type of coating is suitable for use in very aggressive chemical media.
  • Such a two-component epoxy resin coating is available, for example, under the name Sikafloor ® -381.
  • this type of coating offers good surface protection (mechanical resilience) and hardens quickly.
  • the coating can be solvent-free when cured.
  • the coating can be ceramic-reinforced.
  • a two-component epoxy resin coating is available under the name LOCTITE ® PC 7255 TM .
  • Such a coating ensures good protection of surfaces even in very aggressive chemical media. Since the coating is ceramic-reinforced, the surface coated is not only well protected against corrosive substances, but also against abrasive substances.
  • the coating can be sprayed on. Alternatively, the coating can be applied mechanically.
  • Calcium silicate has a very uneven and rough surface. Calcium silicate also absorbs liquids very well.
  • the surface of a calcium silicate board for example, is sealed at least to a large extent, preferably completely, so that only a small amount of the coating needs to be applied.
  • the primer also improves the adhesion of the coating that is subsequently applied.
  • At least a portion of the housing wall can be made of at least one fire protection board or at least one cement-bonded calcium silicate board.
  • the thickness of the housing wall can preferably be between 10 mm and 80 mm If the housing has a square cross-section, the housing wall consists of four housing wall sections that are fixed to one another. Each housing wall section can be made of a fire protection board or a cement-bonded calcium silicate board, for example. Of course, other materials that are sufficiently temperature-resistant are also conceivable.
  • the damper blade can be made of at least one fire protection board or a cement-bonded calcium silicate board. Of course, other materials that are sufficiently temperature-resistant are also conceivable.
  • the shut-off device can be designed as a smoke extraction flap.
  • Smoke extraction flaps are used to keep areas of a building, for example an escape area, smoke-free.
  • the application area of a smoke extraction flap is at a temperature that lies between the ambient temperature of the building area to be kept smoke-free (cold smoke extraction) and a temperature of up to 1000°C or more (hot smoke extraction).
  • smoke extraction flaps must ensure both cold sealing and hot sealing. Due to the potentially high temperatures, the housing, flap, stops and the encapsulation of the drive device arranged on the outside of the housing are usually made of calcium silicate.
  • Smoke extraction flaps are usually triggered by a smoke detector.
  • triggering devices such as a manual triggering device, a remote triggering device, a fire alarm system, a coupler or the like.
  • the energy for opening and closing must be permanently available to the shut-off device.
  • Smoke extraction dampers are designed in such a way that even after they have been triggered, ie after they have been swung from the open position to the closed position, they can still be opened, ie swung into the open position. This also applies in the opposite case.
  • the shut-off device can also be designed as a fire damper.
  • Fire dampers usually have a housing made of metal or calcium silicate plates in which a damper blade made of calcium silicate is pivotably mounted.
  • a fire damper can, for example, be manually operated.
  • an actuating element such as an actuating handle, is usually provided, preferably arranged on the outside of the housing.
  • the damper blade can be fixed in its open position by means of a fixing device against a restoring force and can be pivoted from the fixed position into its closed position by the restoring force after the fixing device has been released, for example in the event of a fire.
  • the restoring force can be generated by a spring, preferably arranged outside the housing.
  • the fixing device is designed, for example, as a fusible link.
  • the damper blade is fixed in its open position by means of the fixing device against a restoring force. For example, in the event of a fire, i.e.
  • the damper blade when the temperature exceeds a value of approximately 72°C, the damper blade is pivoted from its fixed open position into its closed position by the restoring force provided by the spring after the fixing device, for example the fusible link, has been triggered.
  • an intumescent material i.e. a material that foams when heated, inflates.
  • the intumescent material now completely fills any gap that may still exist, for example between the housing and the flap in its closed position. The flap can no longer be opened and must be replaced later.
  • fixing devices such as a thermoelectric triggering device.
  • shut-off device can also be designed as a combined fire protection and smoke extraction damper.
  • the drive device is designed as a spring return motor, for example.
  • a spring in the spring return motor is tensioned.
  • a thermoelectric trigger device which can be an electrical fusible link, for example, causes a voltage interruption.
  • the spring return motor can then no longer counteract the restoring force generated by the tensioned spring, so that the damper blade is closed by the restoring force applied by the spring.
  • an OPEN/CLOSE drive can be used as a drive device for opening and closing the damper blade.
  • the OPEN/CLOSE drive provides a maximum torque of 40 Nm.
  • the limit switches for the OPEN and CLOSED position indicators are usually located inside the OPEN/CLOSE drive.
  • the OPEN/CLOSE drive is controlled via a suitable interface monitoring unit with a control module.
  • the interface monitoring unit supplies the OPEN/CLOSE drive with voltage and monitors when the safety position is reached. It also guarantees that the damper blade closes if there is a voltage drop in a building.
  • the OPEN/CLOSE drive is controlled via a control module, for example. If the control module includes double-layer capacitors, the double-layer capacitors provide a redundant 24 V power supply.
  • thermoelectric trigger element can be connected to an input of the control module in a wire-break-proof manner. In the event of a thermal trigger, the control module closes the damper blade. If the 24V power supply is interrupted, the energy from the double-layer capacitors also closes the damper blade.
  • the control module is preferably located within an enclosure of the OPEN/CLOSE drive and is connected to a controller unit using, for example, two-wire technology.
  • the controller unit consists of a controller including suitable control software and a suitable AS interface. Power supply unit for communication with the control module.
  • the protocol that exchanges data between the control module and the controller has been internationally standardized since 1999 according to EN 50295 and IEC 62026-2.
  • the data transmission and the power supply for controlling the OPEN/CLOSE drive are carried out via a two-wire cable, for example.
  • a two-wire cable for example.
  • both the position and the running time of the damper blade can be monitored.
  • the control module can also be used as a "stand-alone variant". In this case, communication with the controller is not necessary.
  • the manual opening and closing of the damper blade takes place via an input contact on the control module.
  • a smoke extraction damper comprises a motorized drive device
  • an applied voltage is required both for pivoting the damper blade from the open position to its closed position and for pivoting the damper blade from the closed position to its open position.
  • At least one screw preferably passing through the pivot axis, can be provided for the rotationally fixed fastening of the damper blade relative to the pivot axis.
  • a receptacle preferably a receptacle designed as a milling, can be provided in at least one surface of the damper blade for receiving the end of the screw located in the region of this surface of the damper blade.
  • At least one receptacle can be closed with a cover, preferably attached to the flap leaf by means of screws.
  • the cover can be a calcium silicate plate, for example. In such a design, the coating also covers the cover.
  • the shut-off device can comprise an energy storage device. This can be, for example, a battery or an accumulator.
  • the energy storage device can also be designed as a capacitor that is charged when voltage is applied. If, for example, an electrically operated drive device is provided, the damper blade can be pivoted from the open position to its closed position or vice versa from the closed position to its open position even if the voltage is interrupted.
  • the figures show a shut-off device with a housing 2 having a surrounding housing wall 1.
