Definitions

  • the invention relates to a chimney pipe fitting lateral pipe junction on which a connecting part to Example a cleaning door or a pipe socket, gas-tight can be attached.
  • a chimney pipe fitting is also part of the prior art with side pipe branching at or near your Front edge a flange for fastening a Has adapter frame.
  • the pipe branch has moreover a sealing surface to which a connecting edge of a connecting part to be sealed by the adapter can be pressed (DE 197 11 362A1).
  • the adapter frame is open the flange of the pipe branch can be pushed on this in the pushed-on state and has positive in turn fasteners for fastening different connecting parts.
  • the object of the present invention is a chimney pipe fitting with side pipe branch and associated To create connectors that are easy on the Pipe branch can be attached and a perfect gas-tight connection with the fitting guarantee.
  • the provided on the respective connector Spring-elastic, flexible holding arms work with the flange together at the pipe junction in a way that a just plugging the connector onto the pipe branch allowed and by a subsequent rotation of the Connection part around the pipe axis of the pipe branch Spring preload of the holding arms results in which one Connection edge of the connection part to that on the pipe junction provided sealing surface is pressed gas-tight.
  • the increasing spring preload is caused by the rotation of the Connection part achieved in that either the Transverse dimension of that gripped by the holding arms Flange or its thickness, or both together from a location or area of the flange to which the connector is plugged on increases.
  • the flange also increases in thickness on part of it radial extension z.
  • connection parts on the pipe branch is therefore simple, because a connector only with the holding arms on the Flange needs to be pushed on so far that the hook-shaped holding arm ends on the back of the flange come to rest, and then only by one certain angle must be rotated in the circumferential direction.
  • the attachment takes place at one point on the flange the holding arms of the connector without any or only with a minor and manageable Deformation of the holding arms can be attached.
  • a the corresponding attachment point is provided on the flange.
  • the flange locally in its thickness and / or with respect its transverse dimension compared to the wider area reduced.
  • flange thickness for Generation of the spreading force is used, so understand itself that the flange has an invariable transverse dimension, that means can have a circular contour and consequently that Attachment point by reaching behind the flange enabling locally reduced thickness is determined.
  • a plurality of Attachment points may be provided.
  • the pipe branch 3 is with the Chimney pipe section 1 in one piece, the one piece by directly forming the pipe branch 3 or by subsequently gluing in the saddle piece 3 according to FIG. 2 is achieved.
  • the pipe branch 3 or the saddle piece forming this is only slightly above the outer surface of the Chimney pipe section 1 and carries on its front edge a flange 4, which is offset inwards and with the shoulder of the heel forms a sealing surface 5. This extends over the inner peripheral surface of the Pipe branch even further radially inwards; of the behind that part of the inner peripheral surface of the Pipe branch 3 is largely circular-cylindrical.
  • the Flange 4 has a regular oval or elliptical shape Edge contour, through which he has a minimum and a maximum Receives transverse dimension (Fig. 3,4).
  • the minimum cross dimension of the flange 4 is diametrically opposite to each other lying points 41 defined on a right angle line running to the longitudinal axis of the chimney pipe section 1 lie; is the maximum transverse dimension of the flange 4 defined by diametrically opposite points 42, which are on a parallel to the longitudinal axis of the Chimney pipe section 1 extending line. In the area the maximum transverse dimension determined by points 42 of the flange 4 has this at its rear edge 43 each have a slightly curved notch 44 (Fig. 2.4).
  • the flange 4 also has the location of minimum transverse dimension 41 also a minimum Thickness from which the in both circumferential directions Flange thickness increases steadily until it becomes maximum at the point Transverse dimension 42 or in front of the notches 44 a maximum value reached.
  • the connector 8 shown in Fig. 5,6 is a only partially shown pipe socket, which in this case Metal.
  • the pipe socket 8 is circular cylindrical and has a corresponding circular connecting edge 81, with which it rests on a sealing ring 51.
  • Near the Connection edge 81 are 8 holding arms 82 on the pipe socket welded on, diametrically opposite each other are arranged.
  • the holding arms 82 are each by a resilient steel band formed (Fig. 6), which extends from the weld 83 first across the tube axis of the Connection piece 8 extends.
  • the hook opening for Connection edge 81 or flange 4 indicates.
  • the hooked ends 84 In one End portion 85 are the hooked ends 84 in turn angled inwards to the flange 4 so to be able to reach behind that on its rear edge 43 at least in the course of a subsequent rotation of the Connect part.
  • the cleaning door 9 includes a circular steel disc 91, which on its the fireplace interior facing a heat-insulating Layer 92 carries.
  • a steel band 93 is on its outer surface welded, which in turn radially outwards Holding arms 82 forms.
  • the design is correct the holding arms 82 coincide with that previously described, so that a further description is unnecessary here.
  • To the Holding arms 82 is a handle 94 welded.
  • the disk 91 On hers
  • the disk 91 carries a sealing ring 51 on the outer edge region and is therefore on the sealing surface of the pipe branch 3 on.
  • the Handle 94 In a modified version of the cleaning door 9, the Handle 94, without this being shown in the drawing, instead of the welded connection with the washer 91 Have rotary connection with this.
  • the slewing ring is through a bearing journal with a widened head formed, which allows rotation of the handle 94, a however, axial peeling is prevented.
  • the bearing pin In the simplest case can the bearing pin by a rivet or a screw be formed, which are connected gas-tight to the disk 91 is.
  • a lip seal 10 is provided here, which consists of an elastomeric and in view of the occurring Temperatures of heat-resistant material. It shows one hollow cylindrical support body 101, from the Inner surface two obliquely towards its terminal edge Project 102 inclined annular sealing lips 103. Of the Connection edge 102 continues into a sealing flange 104, which projects over the outer circumference of the support body 101.
  • Connection part includes a support ring 105 made of steel, the is sufficiently strong to do this when spreading of the holding arms 82 welded to it Withstand bending moment without noticeable deformation can.
  • the sealing surface 5 directly on the End face of the flange 4 are formed or a Sealing surface can be there as well as in the Embodiments described shoulder provided be. This will make the range of diameters from additional connecting parts are still considerably enlarged.
  • the sealing ring 51 can already be fixed from the outset with the sealing surface or with the connecting edge of the be attached connector to be connected.
  • this material e.g. plastic or metal
  • Is a sealing ring 51 from the outset with the Connection edge of the connector to be attached connected so it may be appropriate on the sealing surface 5 of the flange and / or on the exposed end face of the sealing ring one axially projecting from the respective plane provide annular sealing rib.
  • This sealing rib will by pressing due to the higher surface pressure more deformed, so that even with a rough one Material of the fitting, e.g. B. heavy clay, gas tightness is guaranteed. This also applies in the event that the Connection edge of the connection part immediately sealing function is attributed (cf. the embodiment according to FIGS. 8 to 10).
  • the holding arms of the connecting part can also in principle be attached to a support ring, which in turn is detachable connected to the connector, for example afterwards Kind of a clamp is clamped. This allows the Thereby pressing force of the connecting edge against the sealing surface adjust that the support ring with the holding arms one has a smaller or larger distance from the connection edge.
