Definitions

  • the invention relates to a connecting sleeve for the gas-tight connection of an exhaust pipe to the flue pipe of a chimney according to the preamble of claim 1.
  • a connecting sleeve for the gas-tight connection of an exhaust pipe to the flue pipe of a chimney according to the preamble of claim 1.
  • Such a sleeve is described as an adapter in EP-A-0 672 866 .
  • this known sleeve there is a need to bring an annular support body into the connecting piece of the smoke pipe. Because of this support body, only the portion of the connecting piece diameter left free by the support body can be used for the exhaust gas line. Since sealing material must also be introduced between the support body and the connecting piece, only exhaust pipes with a much smaller diameter than the diameter of the connecting piece of the flue pipe can be attached with the known sleeve.
  • Another disadvantage is the membrane-like behavior of the sealing material.
  • the sealing material can therefore only be deformed to a certain degree. If the deformation is too great, there is a latent risk of the sealing material tearing. Thus, only relatively narrow diameter ranges of exhaust pipes can be covered with one type of seal.
  • the invention has for its object to design a connecting sleeve so that the largest possible proportion of the diameter of the connection piece for the exhaust pipe to be attached is usable and that the largest possible interval of exhaust pipe diameters can be covered with the aid of a sleeve type. This object is achieved by the combination of features of claim 1.
  • the sleeve fixing is moved out of the interior of the connecting piece into the area of the outer jacket of the connecting piece.
  • the sleeve has a sleeve protruding approximately at right angles from its base body, which is put over the outer jacket of the connecting piece formed on the smoke tube.
  • a particularly simple and therefore inexpensive clamp fixation includes claim 3, according to which a commercially available hose or pipe clamp is used for clamp fixation.
  • the clamp fixation also has the advantage that the fit of the sleeve-connecting piece outer jacket does not have to be designed as a transition fit, in which the sleeve is positively placed on the connecting piece. Rather, this fit can be designed as a clearance fit, which considerably facilitates the assembly of the sleeve on the connecting piece.
  • the sealing effect of the sleeve with respect to the exhaust pipe lying in the passage opening is considerably improved by the use of elastic and at the same time temperature-resistant material for the sleeve base body according to the teaching of claim 4.
  • the elastic configuration of the sleeve base body enables the opening edges of the passage opening to be pivoted easily in the central longitudinal direction of the exhaust pipe to form the sealing ring-like contact seat of the sleeve on the outer surface of the exhaust pipe.
  • the diameter of the passage opening is widened by cutting the lines of intersection, which are grouped in a star shape around the passage opening, and thus matched to the outside diameter of the exhaust pipe. It is advantageous in terms of manufacturing technology to also pre-punch the cutting lines. With appropriate tooling, the cutting lines can be pre-punched in the same working stroke as the punched-out opening.
  • the sleeve according to the invention is suitable both for chimneys in vacuum operation, which corresponds to the normal case of chimney operation, and for chimneys in overpressure operation.
  • the sleeve material is usually tested up to a maximum temperature of 250 ° C and designed for continuous operation at 200 ° C.
  • the smoke pipe 1 shown only partially in Fig. 1 extends in the vertical direction 2. From the smoke pipe 1 goes obliquely to the vertical direction 2 from the connecting piece 3.
  • the connecting piece 3 is used, for example, for connecting condensing fireplaces to the smoking pipe 1. Such condensing fireplaces are, for example, in individual residential units arranged thermal baths.
  • the connecting sleeve 5 is slipped over the outer jacket 4 of the connecting piece 3.
  • the connecting sleeve 5 consists of a disk 6 which acts as a sleeve base body. The disk 6 is penetrated in its center by the passage opening 7.
  • the exhaust pipe 8 is inserted into the passage opening 7.
  • the opening edges 9 are pivoted in the central longitudinal direction 10 of the exhaust gas line 8.
  • the opening edges 9 thus form a lip-shaped sealing ring which, in the final assembly state, fits snugly and coherently on the outer surface 11 of the exhaust pipe 8.
  • the space between the outer surface 11 and the opening edges 9 which can be seen in the drawing figure is only present for the sake of clarity in the drawing, but does not exist in reality.
  • the sleeve 12 protrudes from the disk 6 forming the socket body approximately at a right angle, that is to say approximately in the longitudinal direction 10 of the exhaust pipe 8.
  • the sleeve 12 is placed over the end of the connecting piece 3 facing away from the flue pipe 1 such that the inner walls of the sleeve 12 rest against the outer jacket 4 of the connecting piece 3.
  • the pipe clamp 13 is clamped all around the sleeve 12.
  • the drawing shows an application with an exhaust pipe 8, the outside diameter of which is significantly smaller than the inside diameter of the connecting piece 3.
  • the opening edges 9 pivot when the exhaust pipe 8 is inserted into the connecting piece 3 and lie behind kind of a sealing lip in a ring on the outer surface 11 of the exhaust pipe 8.
  • the exhaust pipe 8 is mounted on the connecting sleeve 5 such that the exhaust pipe 8 from the end which later faces the smoke pipe 1 into the connecting sleeve 5 is inserted.
  • the opening edges 9 are not pivoted into the connecting piece 3 in the later final assembly state, but are also facing away from the connecting piece 3 on the outer surface 11 of the exhaust pipe 8.
  • the space required for the opening edges 9 between the inner surface of the connecting piece 3 and the outer surface of the exhaust pipe 8 is eliminated.
  • the inner diameter of the connecting piece 3 is completely usable for receiving the exhaust pipe 8.
