Definitions

  • the invention relates to a flue pipe of a chimney made up of several pipe sections with the features according to the preamble of patent claim 1.
  • a layer of ceramic fiber material for example ceramic fabric or nonwoven, between the tip end of the one pipe section and the sleeve inner wall of the subsequent pipe section , arranged, which also serves as a fastening and sealing means.
  • the layer thickness of the ceramic material is selected so that it exceeds the play between the inner wall of the sleeve and the tip end to be inserted.
  • the object of the present invention is to further improve, in particular to simplify, the construction of a smoke pipe consisting of pipe sections, by creating a possibility of dispensing with fixing the ceramic material to the sleeve or to the tip end during the joining process.
  • the ring Due to the conical shape of the retaining and sealing ring made of ceramic fabric, the ring can simply be inserted into the sleeve or fitted onto the tip end of the subsequent pipe section before the joining process.
  • the smaller diameter of the holding and sealing ring is matched to the tip end of the pipe section to be inserted in such a way that the sealing ring sits on the tip end sufficiently tightly or partially encompasses its end face in order to be entrained up to a certain joining force.
  • This tuning does not necessarily require that the diameter is largely exactly matched to the tip end of the pipe section. Rather, it is sufficient due to the surface roughness of the tip end, which can be relatively pronounced, particularly in the case of ceramic material, if the ceramic fabric is attached to the surface roughness and can thus be taken along.
  • the layer thickness of the ceramic material does not exceed the thickness of the space between the tip end and the inner wall of the sleeve in order to bring about the compression of the ceramic material required for the mounting and sealing after the joining process.
  • the invention is based on the consideration that the ceramic fabric ring is first drawn into the socket with a certain force in the course of the joining process by the pointed end, so that its circumference initially coinciding with the upper socket edge migrates into the socket interior. In this state, the ceramic mesh builds up in the circumferential direction and partially rises from the inner wall of the socket with the formation of folds.
  • the ring with its smaller diameter is matched to the tip end in such a way that its corresponding end section also lies sealingly on the circumference of the tip end.
  • sealing takes place both at the tip end in this contact area and in the vicinity of the upper sleeve edge, where the ceramic fabric is compressed and clamped due to the situation described above.
  • the ring with its end section of smaller diameter is matched to the spigot end so that the end section at least partially encompasses its end face and in the assembled state seals on the socket base lies on.
  • the principle according to the invention for fixing and simultaneously sealing two joined pipe sections together makes it possible to influence the holding force and the sealing solely by the choice of the cone angle of the holding and sealing ring. If the cone angle is relatively large, the result of this is that more ceramic fabric gets into the sleeve for a certain path length than with a small cone angle. This results in a comparatively strong compaction of the ceramic fabric after only a short insertion path.
  • the inner wall of the sleeve can be conically tapered towards the base of the sleeve. This ensures that the compression and clamping of the ceramic fabric takes place at a greater distance from the free sleeve edge, inside the sleeve. In this way, the conicity of the inner wall of the socket can also control the "clamping torque" by means of which the pipe section is fixed in the socket of the subsequent pipe section.
  • metal threads preferably axially extending steel threads
  • metal threads are incorporated into the ceramic fabric of the holding and sealing ring.
  • this causes the part of the ring which still protrudes beyond the upper sleeve edge to fold outwards during the described compression and clamping process of the ceramic fabric and in this way brings about an additional fixation on the end face of the sleeve.
  • the ceramic mesh does not require any special treatment to increase the sealing effect. Because due to the described compression and clamping process, the ceramic yarns and their fibers are pressed together so intensely that a perfect seal against leakage of flue gas is guaranteed. The same applies even more if the area of the ring with a smaller diameter lies tightly on the tip end, since this tightens the tissue in the section between the clamping point and the tightly lying area of the ring, as a result of which the yarns and fibers also seal against one another . However, an impregnation of the fabric, for example with talc, can achieve an even more extensive seal, because this fills all the spaces between the fabrics.
  • Talc has good lubricating properties and is therefore suitable as a lubricant and consequently for influencing the joining force when Joining process.
  • talc does not change up to temperatures of 700 ° C.
  • a graphite paste is also suitable for impregnation in this way, either in combination with talc or on its own. This also fills the spaces between the tissues with a largely inert material that remains unchanged up to high temperatures.
  • the holding and sealing ring 1 shown in FIGS. 1 and 2 in the undeformed state consists of a single layer of a ceramic fabric (eg Al 2 0 3 ).
  • a ceramic fabric eg Al 2 0 3
  • steel threads 2 are incorporated, which give the ring 1 a certain shape retention.
  • the ring 1 tapers from a larger (upper) edge 3 in diameter to a smaller (lower) edge 4 with a cone angle ⁇ which, depending on the surface roughness and the use of a cylindrical or conical inner wall can be chosen within wide limits.
  • the cone angle ⁇ is preferably between 5 and 15 °.
  • the ring 1 can either be manufactured as a conical tubular fabric or can be connected to a ring at the ends from appropriately punched or cut sheet-like ceramic fabric.
  • the connection can be made by stapling, sewing or gluing. Since it is desirable to keep the friction properties of the ring largely uniform over its circumference, the second solution can be thought of by thinning the possibly overlapping strip ends by rolling or the like in order to avoid local thickening.
  • Fig. 5 shows the state of the ring 1 after the joining process, i.e. the interconnected state of two smoke pipe sections 5.
  • the smoke pipe sections 5 each have an enlarged sleeve 6 at their upper end, the width of which is so large that the tip end 7 of the pipe section 5 adjoining it can be inserted with play.
  • the inner walls of the pipe sections 5 arranged one above the other are essentially flush with one another after the joining.
  • the inner wall 8 of the sleeve 6 has a height of, for example, 4 cm and a radial distance from the outer wall 9 of the concentrically inserted tip end 7 of, for example, 2 mm. With this size, the intermediate space is preferably slightly above the thickness of the ceramic fabric from which the holding and sealing ring 1 is made.
  • ring 1 with its lower edge portion 4 lies closely against the outer surface of the tip end 7 and maintains a clear distance from the inner wall 8 of the sleeve.
  • the thickness of the ring 1 increases rapidly upwards; in the upper section of the sleeve 6, the ring 1 is clamped between the sleeve inner wall 8 and the outer wall 9 and strongly compressed. over the ring 1 with its upper edge section 3 extends beyond the upper edge of the sleeve 6 in its original thickness.
  • the tip end 7 has already been pushed a little further into the sleeve 6, as a result of which the ring 1 is partially lifted from the upper sleeve edge and pressed inward and is thereby placed on the outer wall 9 of the tip end 7.
  • the ceramic fabric is also subjected to a compression in the circumferential direction, as a result of which the individual yarns and fibers are brought closer to one another and any gaps between the fabrics are thereby eliminated.
  • the described compression and compression of the ceramic fabric takes on such a degree that the ring 1 is clamped between the walls 8 and 9, so that the ring 1 is prevented from being drawn into the interior of the sleeve until then. Since the end face 10 of the tip end 7 has not yet reached the socket base 11 at this point, a relative movement begins between the tip end 7 and the edge region 4 of the ring 1. The relative movement first manifests itself in an extension of the ceramic fabric, which can be seen in FIG. 5, and subsequently in one The edge area 4 slides on the outer wall 9 of the tip end 7.
  • the end face 10 of the tip end 7 is seated on the socket base 11; by clamping near the upper sleeve edge, the upper pipe section 5 is firmly connected to the lower pipe section 5.
  • the embodiment according to FIG. 6 differs from the embodiment described above according to FIGS. 3 to 5 only in that the lower edge region 4 ′ of the ring 1 is kept narrower relative to the diameter of the tip end 7.
  • the ring 1 will therefore not slide completely onto the outer wall 9 when it is pulled onto the tip end 7 with its edge region 4 ', but at least partially overlap the end face 10.
  • the joining process is otherwise similar to the joining process described above with reference to FIGS. 3 to 5. However, in the last stage of the joining process there is no sliding of the lower edge section 4 'on the outer wall 9 of the tip end 7, but only a certain stretch. 6, the end face 10 of the tip end 7 rests on the lower edge section 4 'of the ring 1 and effects an additional seal there.
  • the exemplary embodiments are explained continuously in connection with a circular cross-section of the pipe sections 5, the sleeve 8, 8 'and corresponding to the ring 1.
  • the invention can also be carried out in connection with tubular sections with an angular cross section, e.g. on pipe sections with a square cross-section.
  • the reference to a conical shape of the ring 1 is to be understood as a corresponding tapering of a ring with a rectangular contour.
  • the ring 1 can also be constructed differently from the embodiment with only one ceramic fabric layer from several layers of ceramic fabric.
  • it can prove to be advantageous to connect the layers of ceramic fabric to one another, if necessary to glue them flat, if the same behavior is to be achieved as with a single-layer ceramic fabric.
  • a connection of the individual fabric layers to one another can be dispensed with.
  • the layers slide against one another, so that, similarly to the embodiment according to FIG. 7, the clamping area is expanded and the clamping point is displaced inwards.
  • taper of the inner wall 8 'of FIG. 7 can also be replaced or supplemented by a corresponding taper of the tip end.
  • other sealants or lubricants e.g. Vaseline or acid putty, to reduce the joining force.
