Definitions
- the invention relates to one of several pipe sections built smoke pipe of a chimney with the features according to the preamble of claim 1.
- the pipe sections at one end to one enlarged sleeve is molded between the spigot end of a pipe section and the sleeve inner wall of the subsequent pipe section a layer Ceramic fiber material, e.g. Ceramic fabric or fleece, arranged, which at the same time as a fastening and sealing agent serves.
- the layer thickness of the ceramic material is so chosen that this the game between the sleeve inner wall and exceeds the tip end to be inserted.
- the pipe sections on one End are each formed into an enlarged sleeve, in which the other pipe end of the adjoining one Pipe section inserted and by means of a ceramic fiber existing ring is fastened and sealed in it (DE-U 295 10 018).
- the cylindrical sealing ring is pressed or baked and is in the sleeve of the lower pipe section inserted to serve to guide the pipe to be attached.
- Wall thickness of the otherwise cylindrical seal down to expand so that the inner wall surface is down tapered.
- the object of the present invention is the described Construction of a smoke pipe consisting of pipe sections to improve, in particular to simplify, by a Possibility is created on a fixation of the Ceramic material on the sleeve or on the tip end of the To dispense with the joining process.
- the ring can simply be inserted into the ceramic mesh before the joining process Sleeve inserted or on the pointed end of the subsequent Pipe section are drawn up. At least in that the latter case the smaller diameter of the holding and Sealing ring on the pointed end of the insert Pipe section matched that the sealing ring on the tip end Sufficiently tight or some of its face encompasses to up to a certain joining force of it to be taken away.
- This vote does not require necessarily that the diameter is largely exact on that Pointed end of the pipe section is matched. Rather, it is enough it due to the surface roughness of the tip end Relatively strong, especially with ceramic material can be pronounced if the ceramic mesh on the Hang in the surface roughness and take it with you can.
- the layer thickness of the ceramic material is not the thickness of the gap between the spigot end and the inside wall of the socket exceed that for the bracket and seal required compression of the ceramic material after the To bring about the joining process. Rather, the invention proceeds from considering that the ceramic mesh ring in the course of Joining process first through the pointed end with a certain force is drawn into the sleeve so that be initially in line with the upper edge of the sleeve Scope migrates into the inside of the sleeve. Stuck in this state the ceramic mesh in the circumferential direction and rises partly from the inner wall of the socket with wrinkling.
- the ring is with its smaller diameter so to the point end matched that it had its corresponding end section also lies sealingly around the circumference of the tip end.
- a seal is found at both the tip end in this case Area as well as near the top of the sleeve instead where the ceramic mesh due to the above formed facts is compressed and pinched.
- the ring is smaller with its end portion Diameter matched to the tip end so that the End portion of its end face at least partially embraces and in the assembled state sealing on the Muffengrund rests.
- the ceramic mesh does not require anything special Treatment to increase the sealing effect. Because due to the the described compression and clamping process Ceramic yarns and their fibers so intensely together pressed that a perfect seal against one Leakage of flue gas is guaranteed. Appropriate applies all the more, even if the smaller in diameter Area of the ring lies tight on the tip end, because hereby in the section between the nip and the tight area of the ring tightened the tissue which also seals the yarns and fibers put together. However, by impregnation of the fabric e.g. with talc an even more extensive Sealing can be achieved because of this all Tissue spaces are filled.
- Talc has good ones Lubrication properties and is therefore suitable as a lubricant and consequently to influence the joining force when Joining process.
- talcum changes up to Temperatures of 700 ° C do not.
- For impregnation on this Way is suitable, either in combination with talc or by itself, also a graphite paste. This too the spaces between the tissues are largely inert Material filled up to high temperatures remains unchanged.
- 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 (for example Al 2 O 3 ).
- a ceramic fabric for example Al 2 O 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 to a smaller (lower) edge 4 with a cone angle ⁇ , which can be selected within wide limits depending on the surface roughness and the use of a cylindrical or conical inner wall.
- the cone angle ⁇ is preferably between 5 and 15 °.
- the ring 1 can either be a conical tubular fabric are manufactured or from corresponding punched or cut sheet-like ceramic fabric to form a ring the ends are connected.
- the connection can be made through Staples, sewing or gluing. Since it is desired the friction properties of the ring on its circumference to keep largely even at second solution should be thought of each other optionally overlapping strip ends by rolling or the like to thin out to give a local thickening avoid.
- the smoke pipe sections 5 point in this embodiment at its upper end each an expanded sleeve 6, the width of which is so large that the tip end 7 of the pipe section 5 adjoining it can be inserted with game.
- the inner walls of the superimposed pipe sections 5 align of coincidence essentially with each other.
- the inner wall 8 of the Sleeve 6 has a height of, for example, 4 cm and one Radial distance from the outer wall 9 of the concentric inserted tip end 7 of, for example, 2 mm. With the size of the gap is preferably slight over the thickness of the ceramic fabric from which the holding and sealing ring 1 is made.
- FIGS. 3 and 4 The joining process of the two described at the beginning Pipe sections 5 with one another is shown in FIGS. 3 and 4 clear.
- the ring is 1 before the actual joining process been drawn onto the outer wall 9 of the tip end 7, so that the lower edge portion 4 with friction on the Spiked 7 sits.
- the bottom one Edge section 4 of the sealing ring 1 so on the outer diameter matched the tip end 7 that the sealing ring 1 with a corresponding circumferential expansion of the ceramic fabric to the tip end up to that shown in FIG. 3 Condition can be raised.
- 3 is the Joining process only carried out so far that the sealing ring 1 the just touched the upper inner edge of the sleeve 6.
- the tip end 7 is already a Sliding further into the sleeve 6, which causes the ring 1 partially lifted from the upper sleeve edge and after pressed inside and against the outer wall 9 of the tip end 7 is created.
- the ceramic mesh experiences at the same time a circumferential compression, through which the individual Yarns and fibers approximated and possibly existing gaps in the tissue are thereby eliminated.
- the end face 10 of the tip end 7 is seated the socket bottom 11; by being trapped near the upper sleeve edge, the upper pipe section 5 is fixed with connected to the lower pipe section 5.
- Embodiments are consistently related to a circular cross-section of the pipe sections 5, the sleeve 8, 8 'and explained according to the ring 1.
- the invention can also be used in connection with the cross section Execute square pipe sections, e.g. on pipe sections with a square cross section. In this case it is Indication of a conical shape of ring 1 as one corresponding tapering of a ring with a rectangular Understand contour.
- the ring 1 can also differ from the embodiment with just one layer of ceramic fabric made up of several layers of Ceramic fabric can be built.
- the layers of ceramic fabric can connect with one another, if necessary over a large area stick if the same behavior as one single-layer ceramic fabric is to be achieved.
- a connection of the individual layers of tissue can be dispensed with. This causes the layers to slide against each other, so that similar to the embodiment of FIG. 7 Extension of the clamping area and a shift of the Clamping point takes place inside.
- taper of the sleeve inner wall 8 'according to Fig. 7 also by a corresponding taper of the Top things to be replaced or supplemented.
- talc and / or graphite can also other sealing or Lubricants, e.g. Vaseline or acid putty, for reduction the joining force.
