Definitions

  • the present invention relates to a system seal for a device for closing a ventilation, especially for fire damper or hatch smoke extraction.
  • a fire damper installed on a duct ventilation, has the function of closing in the event of to prevent the spread of fire by the sheath.
  • a fire damper is usually sealed in a fire wall or installed against it. By closing, the valve closes the passage of the sheath to level of the wall and restores its fire resistance to the latter.
  • the sheaths can be depression or not.
  • One of the most penalizing for a fire damper is the case where the fire is on one side of the valve and the depression on the other side of it. In such a configuration, the depression tends to blow hot air from the side of the valve facing fire, through the valve towards the other side of it not yet reached by the fire, as described in the patent application French n ° 96 08148 in the name of the Applicant.
  • Intumescent joints have disadvantages insofar as they are a delicate implementation, due to the presence of a sheath which surrounds the joint. This sheath is fragile, and it should not be damaged during installation joint place. The ends of the joint must be putties to reconstitute the protective sheath. he these are products that require functional play important for their fixation, and which are priced at comes back high.
  • the object of the invention is to provide a system seal for a device for closing a ventilation, which is of a low cost price, of a simple and fast implementation, which is not fragile, and which has perfect stability in the time.
  • the system it concerns comprising a frame sealed in a fire wall or fixed applied against the latter, and inside which is pivotally mounted at least one blade capable of pivoting between an open position and a position of closure in which it is arranged in the plane of the frame and restore to the wall its fire rating, is characterized in that it comprises at least one strip flexible and resistant to high temperatures fixed over part of its width on the frame or on the blade and intended, on the other part of its width, coming to bear respectively against the blade or frame, or against another strip of the same material attached to the blade or frame.
  • the principle underlying the invention consists in use vacuum to perfect the watertightness of the valve, the part of the sealing strip not fixed on an element deforming under the effect of depression for come to bear against the other element, frame or blade, and seal at the latter.
  • the bending of the sealing strip must be sufficient to compensate for defects in the shape of the valve, frame or blade.
  • the strip seal has a thickness of about 0.1 mm.
  • the sealing strip can be based on mica, based on carbon fibers, graphite fibers, or based on a mixture of these or other fibers, or still silicone-based, the main thing being that the strip withstands temperature.
  • this sealing system comprises two sets of offset sealing strips perpendicular to the plane of the frame and the blade, when the valve is closed, the free parts of the bands of the two series being mounted in opposition.
  • a shutter device comprising a frame, the inside of which is pivotally mounted a blade, around an axis arranged halfway along the opening, and in which the frame, on the one hand, and the blade, on the other hand, are each made from two identical elements of the same thickness and assembled two by two, both elements of the blade being joined together and the two elements of the frame also being assembled together, sealing strips associated respectively with the frame and the blade, are intended to come into abutment against each other the others in the blade closed position, each strip comprising a part fixed by pinching between the two elements of the blade, respectively of the frame, and one part extending from one of these two elements and intended, in the closed position of the blade to come to bear against a strip associated with the frame, respectively with the blade.
  • each sealing strip is fixed permanently on the blade, respectively on the frame, over part of its width, and is fixed on the blade, respectively on the frame on the other part of his width, intended to bear against another strip, by a fusible glue at a temperature of around 80 to 100 ° C.
  • a fusible glue at a temperature of around 80 to 100 ° C.
  • FIG 1 shows a fire damper 2 comprising a frame 3 of square shape intended to be fixed next to an opening to be closed or inside a drove. Inside the frame 2, is pivotally mounted a shutter blade 4 of generally square shape around an axis 5 arranged horizontally at mid-length of the opening 6 which delimits the frame. This blade 4 is swivel between an open position shown in the FIG. 1, in which it allows the passage of air, and a closed position, shown in Figures 3 and 4, in which it is located in the plane of opening the frame.
  • the blade 4 is formed by a shaped part parallelepiped, for example made of refractory material having, on one of its faces, a recess rectangular 7 thick corresponding to half of the thickness of the blade, extending along three edges of it, between two mounting areas of the axis of pivoting 5.
  • This blade comprises, on the other hand, and opening on its other face, a symmetrical recess 8 of the recess 7, relative to the axis of rotation 5 of the blade, formed on the other half of the perimeter.
  • the frame 3 has, for its part, two ribs rectangular 9 and 10 symmetrical to each other by relative to the axis of rotation 5 of the blade 4 and extending each half the thickness of the frame, the distance between the corresponding ends of the two ribs 9 and 10 being substantially equal to the thickness of the blade.
  • the blade 4 is produced at from two identical elements 4a and 4b, each of thickness corresponding to half the thickness of the blade and assembled head to tail.
  • frame 3 it is made from of two elements 3a and 3b of thickness corresponding to the half the thickness of the frame and assembled head to tail to one another.
  • This fire damper is fitted with bands sealing, respectively 12 fixed on the frame 3, and 13 fixed on the blade.
  • the bands 12 are pinched between elements 3a and 3b, and protrude towards the interior at the ribs 9 and 10.
  • the part of the strips which protrude from ribs 9 and 10 is glued on element 3a using a fusible glue to a temperature of the order of 80 to 100 ° C.
  • the bands 13 are, for their part, pinched between the two elements 4a and 4b of the blade 4 and comprise a part which extends to the level of the recesses 7 and 8. In this part, at the level recesses 7 and 8, the strips are glued using the fuse adhesive defined above.
  • sealing is carried out using strips 15, 16 fixed on the outer face respectively of the blade 4 and the frame 3. These bands 15, 16 project relative to the outline of the opening made by the frame, to be able to come to bear respectively against the blade, to the blades 15, and against the frame, for the blades 16.
  • the sealing strips can be made of mica with a thickness of about 0.12 mm.
  • FIG. 7 represents an alternative embodiment of the device of FIGS. 1 to 4, in which the strips 17, 18 fixed respectively on the blade and on the frame to points indicated by dashed lines, are not included in the thickness of two constituent elements of the frame and blade, as was the case previously.
  • Figures 8-10 show three shapes of execution, in which the sealing strips 19, 20, always fixed locally at the locations indicated by mixed lines, form at least one angle along of one of the edges of frame 3 and of the blade 4.
  • a sealing strip 21 is fixed in its central part on frame 3, and its two edges are intended to bear on the blade 4 in the position of closing thereof, one or other of the edges ensuring tightness depending on whether the vacuum is exerted on one side or on the other side of the fire damper.
  • the seal at the axis of rotation 3 can be obtained by a compression joint.
  • Figures 12 and 13 show a hatch smoke extraction 22 comprising a frame 23 on which are pivotally mounted, around vertical axes 24, two blades 25, intended to come to bear against an amount central 26. Sealing when closing the blades 25 is carried out by means of bands 27, 28 mounted respectively on the frame 23 and on the blades 25, and which come into contact in the closed position. These blades are mounted in the same way as in the valve figure 3.
  • the invention brings a great improvement to the existing technique by providing a structural sealing system simple, not very fragile, can be implemented quickly and fixed for example by gluing, without deterioration of the frame and valve blade, and having excellent stability over time.
