Definitions

  • the chimneys are equipped with a chimney pipe to reduce the cross-section.
  • materials have to be used which are able to withstand a constant chemical load (hot sulfuric acid and hydrochloric acid as a condensate component) and the high temperatures.
  • Metal pipes such as stainless steel pipes, chrome steel pipes or inox pipes, etc. have proven to be insufficiently corrosion-proof. Glasses or high-quality plastics such as PVDF (polyvinylidene fluoride) are therefore preferably used.
  • PVDF polyvinylidene fluoride
  • the chimney pipes are usually composed of different pipe pieces and shaped pieces.
  • a problem here is the connection between the individual pipe and / or fittings. This connection should on the one hand hold well and be absolutely tight so that the acidic condensate cannot get out, on the other hand the assembly of the pipe should nevertheless be carried out as simply and quickly as possible.
  • a condensate trap serves to ensure that it develops in the chimney pipe and flows downwards Collect the condensate and drain it from the chimney pipe. It is particularly important when the exhaust pipe of a heating boiler leads vertically away from it, and the condensate cannot be drained off completely into a neutralization box. In this case, there is a risk that the acidic condensate will flow back into the boiler and cause pitting there. It can be both an atmospheric boiler and a condensing boiler.
  • Another known solution consists in tapering one end of each pipe section. The tapering end of each pipe section can then be inserted into the non-tapering end of another pipe section. The strength and tightness of this connection is also insufficient.
  • the problem of tightness arises not only with the connections between the individual pipe and / or piece ken, but also at the inspection openings.
  • the inspection openings allow access inside the pipe for cleaning or testing purposes. They are located in the pipe wall.
  • an opening must also be provided in the brick chimney wall.
  • the opening of the brick chimney wall and the opening of the chimney pipe are connected to something similar to a feed tunnel, a so-called frame. There is very little space in this frame or between the chimney pipe and the chimney wall. It is therefore not possible, for example, to use a door as a lock.
  • a curved cover is used, the edge of which lies against the wall of the chimney pipe around the opening.
  • Old brick chimneys are often not straight or have white displacements. When renovating or expanding a house, the brick chimney was often slanted away at the transition to the new floor.
  • the object of the invention is now to create a chimney pipe with connecting devices which are suitable both for fast, tight and firm connection of two pipe parts and for attaching a cover to the inspection opening, for fastening condensate separators or traps len on the chimney pipe and for the weld-free connection of a flexible profile pipe piece on another flexible profile pipe piece, on molded parts such as inspection openings, boiler connection pieces, chimney end pieces or condensate traps as well as on straight, stiff pipe pieces.
  • the pipe parts are covered with a Special flange connection, or when using flexible profile tubes with a special connection, connected to each other.
  • the flange connection is also used to attach the covers to the inspection openings and to attach condensate separators.
  • the flanges of the flange connection are designed in a rib construction. They are welded to the corresponding pipe parts and fittings by mirror welding before assembly.
  • Flange and counter flange are connected to one another by plastic clips arranged on the circumference of the flange.
  • a sealing ring made of EPDM or Viton is inserted between the flange and the counter flange in a prefabricated groove. It is possible to combine the flange connection with a condensate trap.
  • the plastic clips are fastened to one half of the flange and are clipped onto the counterflange on a correspondingly shaped counterpart.
  • a clamping ring commercially available can take the place of the plastic clip.
  • connection sleeve consists of two fixed pieces of pipe with different cross sections.
  • the thick pipe section is slipped with its end region over the thinner pipe section.
  • the end face of this end region is connected to the outer side of the thin pipe section by an annular connecting wall which runs obliquely inwards.

  • the practical hinge clips 36 ensure that the covers 33 of the inspection openings 34 or the condensate separators 35 do not fall down when they are detached from the flange 1 of the chimney pipe by opening the plastic clips 10.
  • High-quality materials are used for the production of the individual components, which are able to withstand the hard loads to which they are exposed.
  • the plastic polyvinylidene fluoride (PVDF) from which the flange 1 of the Gegenflan ⁇ ch 2 and the Rohr ⁇ tücke are made, is resistant to heat (up to 160 * C), against acids and against UV rays. It is also age-resistant and elastic. Polyvinylidene fluoride is therefore ideal for use in wet, cold, condensing fireplaces.
  • the condensate trap 72 With the proposed condensate trap 72 combined with a flange closure, pitting caused in the heating boiler by back-flowing condensate can be reliably prevented. Thanks to the flange closure, the condensate trap 72 simultaneously fulfills the task of opening a revision. It can be easily opened by opening the plastic clip or by removing the clamping ring from the chimney sweep. Access to the boiler or to the chimney pipe leading to the side is thereby free for inspections or revisions.
  • connecting sleeve 87 flexible profile pipe pieces can be connected to shaped pieces such as inspection openings, boiler connection pieces, chimney end pieces, condensate traps, or rigid, smooth pipe pieces without the use of expensive welding machines.
  • the double connection sleeve also allows two welded pipe sections to be connected without welding.

Abstract

Un tuyau de cheminée comprend des sections de tuyaux reliées les unes aux autres par un joint spécial à bride ou par un joint spécial à manchon. On utilise la jonction à bride pour assujettir des couvercles sur les regards du tuyau de cheminée et pour assujettir des collecteurs de condensé sur le tuyau de cheminée. La jonction à bride peut en outre être associée à un piège à condensé. Le joint à manchon permet de relier, sur le chantier, des sections profilées souples de tuyaux à d'autres sections profilées souples de tuyaux ou à des pièces façonnées, sans qu'il soit nécessaire d'avoir recours à la technique compliquée de soudage en bout à l'aide de réflecteurs. Les brides (1, 2) du joint à bride sont cannelées. La bride (1) et la contre-bride (2) sont interconnectées par des clips en plastique (10). Une bague d'étanchéité (22) en silicone, EPDM, viton ou un autre matériau approprié est insérée dans une rainure préfabriquée entre la bride (1) et la contre-bride (2). Au lieu des clips en plastique (10), on peut également utiliser un collier de serrage disponible dans le commerce.
