Definitions

  • the invention relates to a fire protection shut-off device for ventilation ducts, consisting of a built-in housing with an air inlet opening and an air outlet opening, the air inlet opening being able to be shut off by means of a shut-off device and the shut-off device being held in the open position under spring action and rapidly opening in the closed position at a predetermined temperature.
  • shut-off element consists of wing flaps which are pivotally mounted in the installation housing, which are held in the open position by means of a soldered spring under spring tension and which snap into the closed position after the solder has burst.
  • the two wing flaps are held in the open position on a common or separate pivot axes, forming a free space in the middle of the housing.
  • the bearing axis for the two wing flaps extends over the entire cross section of the housing. This is disadvantageous in terms of flow technology (see FR 22 86 351).
  • the same fluidic disadvantages occur in another known construction with a bearing profile for the wing flaps. From a fluidic point of view, this is disrupted by a bow-like tension spring which engages under the two wing flaps or their mounting in the open position (cf. US 41 46 048).
  • the invention has for its object to provide a fire protection shut-off device for ventilation ducts of the type described above, which is characterized not only by reduced pressure losses, but also by a particularly simple, functional and practically maintenance-free design.
  • a generic fire protection shut-off device in that the built-in housing on its housing side opposite the air inlet opening has a guide socket for a guide rod on the shut-off element and a closing spring surrounding the guide rod, that the shut-off element is designed as a closing plate and the closing spring as a memory spring are.
  • a memory spring is to be understood as a closing spring with a shape memory, which is contracted at room temperature and is activated at higher temperatures and consequently expands.
  • such a memory spring is suitable for use in fire protection shut-off devices, and in the embodiment according to the invention ensures that the locking plate is kept in the open position at room temperature and consequently contracted memory spring, in the event of fire, however, is pressed into the closed position because the memory spring expands relatively quickly due to the developing temperatures and generates sufficient closing forces.
  • the closing plate held in the open position by means of the memory spring and depressed only in the closing position in the event of fire enables practically undisturbed air passage through the fire protection shut-off device according to the invention, so that only minimal pressure losses occur.
  • the locking mechanism is relatively simple and reliable and, in particular, is largely maintenance-free, because the use of rotating locking elements such as wing flaps or the like does not involve rotating parts that are in the air stream and can contaminate them.
  • the guide rod on the locking plate and, on the other hand, the locking or memory spring surrounding the guide rod are suitable for ensuring a sufficiently exact translatory movement of the locking plate in the event of a fire with an expanding memory spring such that the locking plate actually seals the air inlet opening on the opposite side of the housing.
  • the locking plate in the open position can be glued to the associated housing side or housing wall by means of a heat-sensitive adhesive if, for example, an absolutely motion-free seat of the locking plate is to be ensured in the open position even with strong air flow and / or the locking or memory Spring is not attached to the lock plate or its guide rod.
  • This heat-sensitive adhesive releases the locking plate immediately when heat develops, so that the expansion of the memory spring is not hindered.
  • the invention provides that the installation housing as a flat housing with a base plate with the air inlet opening and with a cover attached to the base plate with the formation of edge-side installation flanges is formed that the cover has an open end face to form the air outlet opening, and that the guide socket is arranged on the outside of the cover.
  • the air inlet opening can have a drawn-in inner edge which is surrounded by a fire-resistant plate made of calcium silicate, for example, with the formation of an annular gap, the locking plate having an outer edge which engages in the annular gap in the closed position of the closing plate on the air inlet opening and encompasses the inner edge of the air inlet opening .
  • a fire-resistant plate made of calcium silicate for example, with the formation of an annular gap
  • the locking plate having an outer edge which engages in the annular gap in the closed position of the closing plate on the air inlet opening and encompasses the inner edge of the air inlet opening .
  • the closing spring expediently surrounds the guide rod with a predetermined narrow movement play, and is also inserted with a specified movement play in the guide socket, so that the closing spring and the guide rod when guiding the locking plate from its open position into the closed position as it were work together.
  • the closing spring can be fastened at one end to the guide socket and at the other end to the foot of the guide rod and / or on the closing plate.
  • a fire protection shut-off device for ventilation ducts is shown in the figures, the air flow being indicated by arrows.
  • the basic structure of this fire protection shut-off device consists of a built-in housing 1 with an air inlet opening 2 and an air outlet opening 3, the air inlet opening 2 being able to be shut off by means of a shut-off device and the shut-off device being held in the open position under spring action and rapidly opening in the closed position at a predetermined temperature.
  • the installation housing 1 has on its housing side opposite the air inlet opening 2 a guide stub 4 for a guide rod 5 on the shut-off element and a closing spring 6 surrounding the guide rod 5.
  • the Shut-off device is designed as a closing plate 7.
  • the closing spring 6 is designed as a memory spring contracted at room temperature, which expands at higher temperatures as a result of the heat development resulting from a fire and presses the closing plate 7 onto the air inlet opening 2 in the closed position.
  • the closing plate 7 is glued to the associated housing side by means of a heat-sensitive adhesive 8.
  • the installation housing 1 is designed as a flat housing with a base plate 9 with the air inlet opening 2 and with a cover 11 attached to the base plate with the formation of installation flanges 10 on the edge.
  • the cover 11 has an open end face to form the air outlet opening 3.
  • the guide socket 4 is arranged on the outside on the cover 11.
  • the air inlet opening 2 has a drawn-in inner edge 12, which is surrounded by a fire-resistant plate or plates 13 made of calcium silicate, for example, with the formation of an annular gap.
  • the locking plate 7 has an outer edge 14 which, when the locking plate 7 is in the closed position, engages in the annular gap 15 on the air inlet opening 2 and engages around the inner edge 12 of the air inlet opening 2.
  • the built-in housing 1 or its cover 11 is surrounded by fire-resistant plates 16 or a fire-resistant extension at hood height.
  • the air outlet opening 3 delimited by a plate 16 or the expansion opens into a ventilation duct 17 parallel to the plate or hood.
  • the closing spring 6 surrounds the guide rod 5 with a predetermined range of motion and even with a predetermined range of motion inserted into the guide socket 4. Furthermore, the closing spring 6 can be fastened at one end to the guide stub 4 and at the other end to the foot of the guide rod 5 and / or on the closing plate 7.
  • the closing plate 7 pressed by the memory spring into the closed position as a result of thermal expansion is indicated by dashed lines.
