Definitions

  • the invention relates to discharge structures for closed gas appliances that extend through a wait of a building, particularly discharge structures extending through facades, said discharge structures comprising or pipe bend.
  • Such discharge structures are widely known.
  • The are usually provided with a double line, namely a supply line for supply of combustion air to the boiler and a discharge line concentrically situated within it for discharge of, flue gasses from the boiler to the outside.
  • a discharge structure as described in the preamble of claim 1 and a pipe bend as described in the preamble of claim 14 are known from GB-A-1.526.162.
  • the discharge structure should particularly in exterior wall ducts provide a transition of the vertical line portion coming out of (or going to) the boiler -usually pipe stubs on the exit/entrance of the boiler- to the horizontal line portion extending through the facade.
  • a arch piece can be used which comprises two concentric pipe members, that can be connected to both concentric lines
  • the mounting ease for the fitter is strongly increased, because the pipe bend can be brought in its place in radial/tangential direction around the bent inner pipe. This can particularly even take place when the inner pipe has already been mounted. Because the pipe bend can be placed after the inner pipe has been placed, the fitter can check the connection of the inner pipe to the boiler. Furthermore as a result of the manner of dividing, forming this portion of the outer pipe is made easier and there is a larger degree of freedom in design details. Because of the connecting portions of the air supply line, in particular the connection to the boiler and the portion of the outer pipe situated upstream, the pipe bend can be kept in its place independent of the inner pipe, so that size tolerances are less troubling when mounting. In the bend the outer pipe and the inner pipe need not necessarily run concentrically.
  • connection surfaces extend in pipe bend direction, so that a dividing area is obtained which is as short as possible.
  • pipe bend is built up from two shell members.
  • the invention provides a discharge structure, in which the outer pipe is provided with a pipe bend at the inner end, which is longltudinally divided into two halves placed against each other, that preferably are symmetrical.
  • the pipe bend members may be connected to each other by means of screws, an elastic circumferential band, a snap connection or the like, preferably in a non-permanent manner.
  • profiles are provided for sealingly clamping the members of the pipe bend to each other.
  • the fitter then arranges the pipe bends around the inner pipe and subsequently attaches them onto each other by means of clamping profiles, which also ensure seating.
  • the outer pipe is formed for radially engaging the outer ends of the pipe bend in a clamping manner, which makes the placement very easy.
  • said ends preferably are situated radially offset to the inside, in order to thus define a portion which is narrowed over a wall thickness.
  • the inner pipe and/or the outer pipe Is/are built up from pipe parts that are telescopically slidable with respect to each other.
  • the invention further provides a method for fitting a discharge structure to gas appliances, as described in claim 14.
  • a supply end piece is placed at the outer end of the inner pipe, which supply end piece is provided with air flow guiding means that are situated in flow line with the annular line and with means for restraining the inner pipe in outward direction.
  • the restraining means comprise stop surfaces cooperating with the end edge of the inner pipe.
  • the supply end piece comprises means for attachment to the outer end of the outer pipe, preferably for a snap attachment.
  • the supply end piece thus forms a means with which the outer pipe and the inner pipe are secured in outward direction with respect to each other.
  • a discharge end piece can be placed in the outer end of the inner pipe, which discharge end piece is provided with discharge gas flow guiding means that are situated in flow line with the gas discharge line and in which the discharge end piece is provided with means for restraining the supply mouthpiece in outward direction, preferably in the form of stop surfaces.
  • said restraining means comprise stop surfaces cooperating with the end edge of the supply mouthpiece.
  • the end mouthpiece is attached here to the inner pipe, preferably by means of clamping it thereon.
  • supply mouthpiece and/or discharge end piece can also be used in other discharge structures, for instance the one having a straight course from the boiler.
  • a pipe formed as a unity having substantially an L-shape in side view and having a relatively long stretched portion and a relatively short portion perpendicular to it, is used as inner pipe member.
  • a discharge structure for closed gas appliances comprising two pipes extending concentrically into each other, in which the outer pipe and the inner pipe each have an inner end at the side of the boiler and an outer end at the side of the outside air, in which the inner pipe is a flue gas discharge pipe and both pipes define a annular line with each other for air supply to the boiler, the inner pipe comprising two portions, which in flow direction are in line which each other, forming a unity with each other and are situated at an angle to each other.
  • the inner pipe preferably comprises an elbow portion formed with it as a unity.
  • a discharge structure for closed gas appliances comprising two pipes extending concentrically into each other, in which the outer pipe and the inner pipe each comprise an inner end at the side of the boiler and an outer end at the side of the outside air, in which the inner pipe is a flue gas discharge pipe and both pipes define and annular line with each other for air supply to the boiler, in which at the inner end the inner pipe is provided with arched portion formed with it as a unity.
  • the boiler arrangement 1 comprising a boiler 3 and a discharge structure 4 for it.
  • the boiler 3 has a pipe stub 24 in the top side for connection of a gas discharge pipe and a pipe stub 25 situated concentrically around it for connection of an air supply pipe.
  • the boiler arrangement 1 is near an exterior wall or facade 2, in which a duct 11 has been made through which the discharge structure 4 can extend to form a connection between the outside air and the boiler 3, in particular the aforementioned pipe stubs 24, 25.
  • the discharge structure 4 comprises a first inner pipe 5 and a second inner pipe 9 telescopically and snugly accommodated therein, both pipes for instance made of aluminium.
  • the first inner pipe 5 consists of a pipe portion 6 which is bend over 90 degrees and a straight pipe portion 7 formed with it as a unity.
  • the first inner pipe 5 is provided with an annular chamber 30 opening to the inside, in which a rubber sealing ring 18 can be accommodated for sealing against the pipe stub 24.
  • the first inner pipe 5 is provided with an annular chamber 28 opening to the inside, in which a rubber sealing ring 16 can be accommodated for sealing the straight pipe portion 7 against the second inner pipe 9.
  • the discharge structure 4 further comprises a straight outer pipe 8 and a second outer pipe 10 telescopically and snugly accommodated therein, both pipes for instance made of zenzidmir galvanized steal or synthetic material.
  • the first outer pipe 8 is painted white for the sight inside the house.
  • a pipe bend 19 is provided, which is bent around the centre point M, over 90 degrees with both the inner edge and the outer edge, as shown in figure 1.
  • the pipe bend 19 can be made by means of injection moulding with synthetic material or an aluminium or aluminium alloy, and then be painted white for aesthetic reasons.
  • first outer pipe 8 At the inner end the first outer pipe 8 is provided with an annular chamber 31 opening to the outside, in which chamber a rubber sealing ring 33 can be accommodated for sealing against the inner wall of the pipe bend 19.
  • first outer pipe 8 At the outer end the first outer pipe 8 is provided with an annular chamber 32 opening to the inside, in which chamber a rubber sealing ring 17 can be accommodated for sealing against the outer surface of the second outer pipe 10.
  • the second outer pipe is furthermore provided with snap holes 29 at its outer end, of which snap holes the function will be explained below.
  • the pipe bend 19 is divided into two identical longitudinal halves 20a, 20b.
  • Said longitudinal halves are designed such that they can easily be released from a mould. They are both provided with outer edges 40, 41 (see figure 4) with which they can be placed flat against to each other.
  • the inner edges of said longitudinal halves are formed correspondingly.
  • the outer edges 40, 41 -and therefore the inner edges as well- are formed with a tangential turn, to define a hook shape.
  • FIG 5 an alternative is shown, in which the inner end of the pipe bend 119 (which just like the pipe bend 19 is longitudinally divided) is slid into an annular groove 125 on the boiler an at the outer end is provided with a narrowed portion 123.
  • Both longitudinal halves 122a, 122b are placed one after the other into the groove 125, then placed (plain joined) with their longitudinal edges against each other, and subsequently the pipe 110 is clampingly slid over the portion 123 with the inner end, after which the pipe bend 119 is retained at both ends.
  • An additional fastener for the longitudinal edges can be dispensed with here, as a result of the clamping at the ends.
  • a sealing along said longitudinal edges could also possibly be dispensed with.
  • the discharge structure 4 further comprises an air flow guide 12, for instance made of synthetic material or cast aluminium, comprising an outer ring 34, an inner ring 38 situated radially within it and axially outside of it and a number of radial fins 26 formed as a unity with said inner ring.
  • an air flow guide 12 for instance made of synthetic material or cast aluminium, comprising an outer ring 34, an inner ring 38 situated radially within it and axially outside of it and a number of radial fins 26 formed as a unity with said inner ring.
  • the outer ring 34 is provided with snap protrusions (not shown), which can snap into the holes 29 in the second outer pipe 10, in order to fix the guide 12 on the pipe 10.
  • the fins 26 abut the outer surface of the second inner pipe 9.
  • the guide 12 thus provides a means for concentrically retaining the second inner pipe 9 with respect to the second outer pipe 10.
  • the inner ring 38 is provided with a shoulder flange 35 extending to the inside, against which the end edge of the second inner pipe 9 abuts.
  • the guide 12 provides a means for securing the second inner pipe 9 axially to the outside with respect to the second outer pipe 10.
  • the air flow guide 12 is provided with a little flange 37, on which a rubber sealing sleeve 14 can be attached.
  • the air flow guide 12 is provided with an opening bounded by the flange 35, in which opening a gas flow guide or gas flow grid 13, for instance made by casting aluminium or an alloy of aluminium, can be clamp fittingly accommodated.
  • Said grid 13 is provided with an middle bush 36 from which radial fins 27 extend.
  • the fins 27 and the bush 36 are wing-shaped in cross-section for lowered flow resistance.
  • the fins 27 at the outer end form an annular stop 39 extending to the inside, with which stop the end edge of the inner pipe 9 is retained.
  • the mounting takes place in the following manner.
  • the parts 9, 10, 12 and 13 and sleeve 14 are pre-assembled in the factory.
  • a snap connection is realised in the holes 29 and the gas flow guide 13 is clampingly fixed.
  • the outer pipes 8, 10 and the inner pipes 5 and 9 are brought at the correct length by extending or retracting.
