Definitions

  • the invention relates to a device for connecting two sections running at an angle to each other Air off-gas line.
  • Air-exhaust gas lines are used for combustion devices that are independent of ambient air used, for example for boilers, especially for condensing boilers.
  • the air-exhaust pipe connects the combustion device with the chimney head.
  • the internal exhaust gas routing guides the flue gas to the chimney head and the outside air duct, which forms an annulus with the exhaust gas duct supplies the Combustion device with suction from the atmosphere Combustion air.
  • the air-exhaust pipe must be used for regular inspections be accessible.
  • the chimney sweeper must have the option have both the air duct and the exhaust duct inspect.
  • the inspection is preferably carried out at the deflection points the air-exhaust pipe instead.
  • the invention has for its object a convenient and still enable reliable inspection, namely in a space-saving way.
  • the cap of the outer Pipe elbow removed. This creates the slanted opening accessible from the outer pipe bend. It opens the direct Insight into both at an angle to each other Air duct branches.
  • the lid that the Socket of the inner pipe bend is closed, accessible. He can be removed and allows direct insight in the branch of the exhaust system, which is the continuation of the nozzle. In the at an angle to it Branch of exhaust gas routing is always without further aids still an angled look possible.
  • the sloping opening of the outer Pipe bend offers the possibility of the inner pipe bend in "screw in" the outer elbow.
  • the outer pipe bend So does not have to be excessively large to a To allow insertion of the inner pipe bend.
  • the two pipe bends each have an insertion end and a sleeve end on the installation of the connector allow in the air-exhaust pipe.
  • the facility is preferably installed at that deflection point the vertical pipe section coming from the boiler in redirected the horizontal line section leading to the chimney becomes. Accordingly, those are vertically downward Arms of the pipe bends are designed as insertion ends.
  • the other arms, preferably at an angle of something protrude more than 90 ° are designed as socket ends. Due to the gradient, condensate can accumulate in the exhaust pipe has put down to the boiler.
  • the nozzle of the inner pipe bend is practically on the axis of the socket end of the inner pipe bend, however also slightly inclined to drain condensate to enable. After removing the cover, the direct View of the horizontal branch of the exhaust system released.
  • the caps of the outer pipe bend also lie essentially on the axis of the socket end of the outer pipe bend. After removing the cap, the ring-shaped air ducts are Visible in both directions.
  • connection device is easily possible.
  • the device at the transition to the vertical in the fireplace Line section are arranged.
  • the angle can also between the arms of the pipe bends much more clearly deviate from 90 ° than it is for achieving a slope is required for the condensate.
  • the plane in which the opening of the outer pipe bend is perpendicular to the plane that spanned by the axes of the two arms of the outer pipe bend becomes. It is particularly advantageous that the Plane in which the opening of the outer pipe bend lies with the axes of the two arms of the outer pipe bend Forms an angle preferably of substantially 45 °. The opening is therefore symmetrical to both arms of the outer Pipe bend.
  • cap that closes the opening of the outer pipe bend, a tubular rear end closed Continuation of one of the arms of the outer pipe bend forms. It is particularly advantageous that the cap the nozzle of the inner pipe bend. This offers optimal Installation and assembly conditions.
  • the flow guide element is preferably from the cover, which closes the nozzle, held in the latter.
  • the flow guide can be part of the cover form.
  • the cover assumes a defined locking position, otherwise the flow guiding element in turn is an obstacle to flow would form.
  • the groove on the inner surface of the nozzle is preferred continuously formed so that any condensate can be dissipated.
  • the flow guide element can easily be a full body be trained. More advantageous because it saves material and can be produced by injection molding, is an apprenticeship of the flow guide as a hollow body open to the outside. It is preferably located inside the hollow body a web that acts as a handle for pulling out the flow guide serves. Is the flow control element as a full body trained, you bring an appropriate handle on its outer surface.
  • the device according to Figure 1 has an outer pipe bend 1 on that with a vertical arm 2 in the form of an insertion end and with a substantially horizontal arm 3 is provided in the form of a sleeve end.
  • the outer pipe bend 1 contains an inner pipe bend 4, which also has a vertical arm 5 in the form of an insertion end and an im essential horizontal arm 6 in the form of a sleeve end is provided.
  • the device is used to create a vertical, section leading to a condensing boiler Air exhaust pipe with an essentially horizontal, to connect to a chimney leading pipe section. The latter has a slight gradient in order to collect condensate Boiler attributed.
  • the line sections are in Figure 1 not shown.
  • the outer pipe bend is 1st in the rearward continuation of his two arms 2 and 3 with an opening 7 provided. This lies on a level that with the two axes of arms 2 and 3 an angle of im forms essentially 45 °.
  • the level in which the opening 7 is perpendicular to that plane of the axes of the two arms 2 and 3 is spanned.
  • a cap 8 is used can be plugged onto a web 9, with the interposition a sealing ring 10, the groove 11 of the web 9 is added.
  • the sealing effect of the sealing ring 10 is of secondary importance since the cap 8 is not the exhaust system the air-exhaust pipe closes, but theirs Air duct.
  • the sealing ring 10 serves to Plug connection between the cap 8 and the web 9 under Secure preload.
  • the inner edge 12 is chamfered.
  • the cap 8 practically forms a rearward extension of the arm 3 of the outer pipe bend 1.
  • the inner pipe bend 4 has a nozzle according to FIG 13, which forms a rearward extension of the arm 3.
  • the connector 13 serves to receive a flow guide element 14, the formation of which is clearer from Figure 4.
  • the flow guide element 14 is open at the rear Hollow body formed and has a circumferential flange 15, with whom he is on a complementary shoulder in Supported inside the nozzle 13. It is in the lower area provided with a wedge-shaped projection 16 which in a complementary, not shown in Figure 3 groove on the inner surface of the connector 13 engages. That way is a Inserting the flow guide element 14 into the socket 13 of the inner pipe bend 4 only in a defined angular position possible. So this is crucial because the flow guide element 14 with a toroidal deflection surface 17 is provided.
  • Their shape is best from the perspective view of Figure 5. Die Differed embodiment shown there differs differs from that of Figure 4 only in that the cylindrical Section is longer and that the wedge-shaped Projection 16 is not the entire length of the cylindrical portion extends.
  • the flow guide element 14 serves to the exhaust gas flow gently from the arm 5 of the inner pipe bend 4 in its arm 6 and thereby the otherwise to avoid occurring pressure losses.
  • the flow guiding element 14 In the assembled position, the flow guiding element 14 from a cover 18 which holds the opening of the nozzle 13 of the inner pipe bend 4.
  • the lid 18 can in the nozzle 13 can only be screwed in when the flow guide 14 inserted sufficiently deep into the socket is, that is, with its projection 16 in the complementary Engages groove and accordingly its predetermined Occupies the angular position.
  • A is used to pull out the flow guide element 15 internally formed approach 19, which is gripped with two fingers can be.
  • the inclined opening 7 of the outer pipe bend 1 enables easy installation of the inner pipe bend 4.
  • the latter can through the opening 7 in the outer Pipe elbow 1 can be "screwed in”. Additional space through Enlargement of the outer pipe bend 1 is not necessary.
  • the nozzle 13 is inner pipe bend 4 within the cap 8 of the outer pipe bend 1.
  • the cap 8 is removed from the outer pipe bend 1. Then are both in the horizontal and in the vertical line section the ring-shaped air ducts are freely visible. Also the cover 18 of the inner pipe bend 4 is optimally accessible. It can be easily unscrewed by hand, after which the flow guide 14 without difficulty can be pulled out of the nozzle 13. Then the one to the Arm 6 of the inner pipe bend 4 connecting horizontal section the exhaust duct can be viewed directly. Only the one the vertical section connecting the arm 5 requires use a mirror, which, however, is standard equipment heard the chimney sweep.
  • connection device A particularly advantageous feature of the connection device is that all components, with the exception of the sealing elements, in the injection molding process made of plastic can be produced.
  • the orientation of the oblique Opening of the outer pipe bend can be chosen differently, whereby however, the orientation shown is currently optimal is seen. Furthermore, the insertion and coupling ends the pipe bends are interchanged, for example even for one of the two pipe bends.
  • Another The inner pipe bend offers a possibility of modification. He can be designed as a T-piece, the arm 6 directly in the Neck 13 passes. However, there is no possibility the nozzle 13 with a slope for draining condensate to provide. The angle between the arms of the pipe bends can deviate strongly from 90 °.
