Definitions

  • the invention relates to a tubular coupling piece, particularly for use in a pipe system of a ventilation or flue gas discharge channel, and to an assembly of a coupling piece and pipe segment.
  • the invention also relates to a branch pipe for use with such a coupling piece, for instance for connecting thereto a combustion device in the case of a pipe system operating as flue gas discharge channel, or for instance a ventilation device or ventilation grille in the case of a pipe system operating as a ventilation channel.
  • Separate or combined ventilation and flue gas discharge channels are installed in practice for ventilation purposes, such as for instance for supplying and/or discharging fresh air to and/or from a space, for discharging flue gases from heating devices or other combustion devices such as ovens, and for instance for supplying combustion air thereto.
  • Such ventilation and flue gas discharge channels are constructed nowadays from plastic or metal tubes or pipes, such as tubes or pipes of polypropylene, aluminium or stainless steel.
  • the pipe material to be selected depends here on, among other factors, the type of combustion device, i.e. the type of combustion material such as gas, oil or wood, the final temperature of the flue gas to be discharged, which in higher efficiency devices will be lower than in the case of lower efficiency devices, and the degree of condensation in the pipe system.
  • these ventilation and flue gas discharge channels may still consist of brickwork or concrete or other stone or ceramic shafts or chimneys, or ventilation or flue gas discharge shafts assembled from galvanized pipes.
  • these galvanized pipes are highly susceptible to corrosion, whereby leakages occur in the pipe system after a period of time.
  • pipe systems constructed from mutually coupled pipe segments are arranged where possible in practice as ventilation and/or flue gas channels in the existing ventilation and flue gas discharge shafts. Not only ventilation and flue gas discharge channels to be replaced but also those to be newly installed are constructed in practice in the form of pipe systems assembled from mutually coupled pipe segments.
  • Tubular coupling pieces also referred to as sleeves, are usually applied for coupling the pipe segments in longitudinal direction.
  • these coupling pieces are provided internally with one or more stops, such as ribs or the like, running around the peripheral wall.
  • tubular coupling pieces are provided with at least one connecting opening for connection thereto of a branch pipe or branch pipe part.
  • the branch pipe then leads to an appliance to be connected to the pipe system.
  • the stop or stops formed in this coupling piece serves or serve the purpose, among others, that the connecting openings cannot be blocked by a pipe element received in the coupling piece.
  • vapour such as water vapour
  • this condensed fluid or condensed liquid flows downward in the pipe system under the influence of gravitational force.
  • a part of the condensed fluid will of course also evaporate again and be discharged with the flue gas when sufficiently hot flue gas is for instance discharged from a flue gas discharge connected to the pipe system.
  • German patent application DE 43 12 094 A1 and the British patent application GB 2 415 033 disclose a tubular coupling piece particularly for use in a pipe system of a ventilation or flue gas discharge channel, which coupling piece has an inlet end and an outlet end for connection to a pipe segment of the pipe system and wherein the coupling piece is provided in its peripheral wall between the inlet end and the outlet end with at least one connecting opening for connection of a branch pipe thereto, wherein the coupling piece is further provided with a stop for a pipe segment extending internally over a distance in radial direction around the peripheral wall, which stop is embodied as fluid collection channel for collecting fluid moving during use along the peripheral wall in the coupling piece, wherein the fluid collection channel connects to the at least one connecting opening.
  • This fluid collection channel can for instance consist of an approximately U-shaped peripheral channel, the open side of which is directed toward the inlet end of the coupling piece. Having the fluid collection channel also connect to a connecting opening achieves that the collected liquid can, if desired, be discharged via a branch pipe or branch pipe part connected to the connecting opening and a device, such as a combustion device, connected thereto. Modern combustion devices do after all generally themselves have a discharge for discharging, for instance via a sewer connection, condensed fluid formed in the device. A problem then however occurs when the collected fluid or condensate may not or cannot drain via the connecting opening.
  • the invention has for its object to provide a solution for the purpose of allowing fluid, such as condensed fluid, collected by a fluid collection channel to also drain in a controlled manner when the connecting opening is closed or when collected fluid may not be discharged via the connecting opening and a branch pipe connected thereto.
  • the fluid collection channel debouches into the at least one connecting opening and the part of the fluid collection channel debouching into the at least one connecting opening is provided with a fluid throughflow channel connecting internally to the peripheral wall of the coupling piece for the purpose of draining through the coupling piece fluid collected by the fluid collection channel.
  • the part of the fluid collection channel debouching into the connecting opening is provided with a fluid throughflow channel connecting internally to the peripheral wall of the coupling piece and having a fluid throughflow opening for the purpose of draining through the coupling piece fluid collected by the fluid collection channel.
  • the solution according to the invention thus provides the option of guiding the collected fluid via the fluid throughflow channel or fluid overflow channel back into the coupling piece.
  • Such a situation can for instance occur when the connected device does not have its own condensation discharge, or for instance in the case of a ventilation grille or the like.
  • the fluid collection channel arranged, as seen in the direction from the inlet end to the outlet end of the coupling piece, at the bottom of the connecting opening and connects thereto. That is, the fluid collection channel is open from the connecting opening.
  • the dimensions of the channel i.e. the collecting volume thereof, can be adjusted to the extent of expected condensation.
  • a channel will generally suffice with a width and height of for instance 5-10 mm.
  • the fluid throughflow channel is provided in the direction towards the peripheral wall of the coupling piece with a fluid flow resistance.
  • a fluid or liquid flow resistance achieves that the collected fluid is preferably discharged in the first instance via a connected branch pipe. Only from a certain level will collected fluid also be able to flow back into the coupling piece via the fluid throughflow channel.
  • the quantity of fluid flowing into the branch pipe can be adjusted by adjusting the flow resistance.
  • the flow resistance ensures that, as soon as fluid begins to flow back into the coupling piece, a certain flow of fluid also occurs in the fluid collection channel, whereby the fluid in the collection channel is 'refreshed', resulting in no or far fewer aggressive substances remaining behind in the fluid collection channel than without such a flow.
  • the fluid flow resistance is formed by the fluid throughflow channel rising from the part of the fluid collection channel debouching into the connecting opening to the peripheral wall of the coupling piece.
  • the fluid throughflow channel preferably rises here with a uniform inclination.
  • the fluid throughflow channel or fluid return flow channel is arranged in the debouchment.
  • the coupling piece For connection of a branch pipe to a connecting opening the coupling piece is provided, in an embodiment, with a tubular flange protruding outward over a distance transversely of the peripheral wall of the coupling piece, wherein the fluid collection channel is formed over a distance along the flange and connects thereto.
  • the flange is formed inclining in the direction of the outlet end of the coupling piece.
  • the angle of inclination relative to the normal to the peripheral wall of the coupling piece amounts, in this embodiment, to only a few degrees.
  • the flange is provided on its outer periphery with at least one sealing ring so that the at least one sealing ring engages fluid-tightly on the inner periphery of a branch pipe to be arranged over the flange.
  • the flange is provided with attaching members for attaching a branch pipe or branch pipe part releasably to the coupling piece.
  • attaching members for attaching a branch pipe or branch pipe part releasably to the coupling piece.
  • attaching members in the form of a screw coupling.
  • An embodiment as screw coupling has the advantage that the force required to slide a branch pipe over the sealing ring or gasket on the outer periphery of the flange, which force can be relatively great in the case of a coupling piece received in a flue gas discharge channel because it is precisely here that an exceptionally good fluid-tight seal is essential, can be generated relatively easily by means of a screwing movement.
  • the attaching members comprise at least a first and second nose-shaped member protruding outward from the peripheral wall of the coupling piece, which nose-shaped members are disposed opposite each other at a distance from the flange adjacently thereof, with a connecting groove facing toward the flange for receiving therein a radially outward protruding connecting lip of a branch pipe to be arranged over the flange.
  • the connecting lip of the branch pipe and the connecting groove in the attaching members form a fitting screw thread connection in the form of a bolt/nut connection, the attaching members of which form the nut part and the branch pipe the bolt part.
  • the screw coupling is embodied as self-positioning screw coupling, wherein an end of a branch pipe for use with a coupling piece is formed for receiving the flange therein, wherein the radially outward protruding connecting lip is a single helical revolving connecting lip with a pitch distance such that, when the revolving connecting lip is placed against the nose-shaped members and in this position the branch pipe is then rotated, the connecting lip engages automatically in the connecting grooves of the nose-shaped members.
  • Such a self-positioning screw coupling facilitates the connection of a branch pipe to the coupling piece, particularly in the case of connections at locations which are difficult to access, or for instance a connection via an opening in an existing shaft.
  • the revolving connecting lip takes a resilient form over a distance in axial direction of the branch pipe such that at the position of this resilient part the pitch distance of the revolving connecting lip differs.
  • this resilient part forms a discernible indication that the branch pipe has been screwed a sufficient distance over the flange, and also forms a barrier, in the form of a safety catch, against loosening of the branch pipe due to vibrations or temperature fluctuations or the like.
  • a similar effect is obtained with another embodiment of the branch pipe wherein the revolving connecting lip takes a resilient form over a distance in radial direction of the branch pipe such that at the position of this resilient part the connecting lip protrudes further outward in radial direction than the remaining part of the revolving connecting lip.
  • Such a screw coupling provides for a safe and mechanically secure connection of a branch pipe to a coupling piece.
  • the invention also provides a cover for fluid-tight closure of a connecting opening, this cover corresponding in respect of the part to be connected to the coupling piece to the end of the branch pipe to be connected to the connecting opening, and wherein the other end of the branch pipe is closed.
  • the internal diameter of the part of the branch pipe not engaging on the flange is smaller than the internal diameter of the flange. This creates an effective barrier to condensation discharge via the branch pipe so that the fluid collected in the fluid collection channel flows via the fluid throughflow channel back into the coupling piece.
  • the branch pipe can of course be provided, with the same effect, with an internal radially protruding elevation or the like which acts as barrier to condensation discharge via the branch pipe. This can in fact also be interpreted however as a reduction in the diameter of the branch pipe as described above.
  • the fluid collection channel is formed as double-sided collection channel for collecting both from the inlet end and from the outlet end fluid moving along the peripheral wall during use.
  • the invention also provides an assembly of a coupling piece and a pipe segment connected fixedly to each other, particularly wherein the pipe segment and the coupling piece are welded together.
  • a pipe system 15 which in the shown example and as seen in the direction from the ground floor 11 to the roof 13 comprises a first cylindrical pipe segment 25, a second cylindrical pipe segment 26 and a third cylindrical pipe segment 27 which have connecting thereto in each case a first cylindrical tubular coupling piece 28, a second cylindrical tubular coupling piece 29 and a third cylindrical tubular coupling piece 30 located at a distance from each other in longitudinal direction in the flue gas discharge shaft 14.
  • the first pipe segment 25 is received fitting with an end in the first coupling piece 28 and received fitting with another end in the second coupling piece 29.
  • the second pipe segment 26 is received fitting with an end in the second coupling piece 29 and received fitting with another end in the third coupling piece 30.
  • the third pipe segment 27 is received fitting with an end in the third coupling piece and the other end of the third pipe segment 27 ends on the roof 13 of the building in an end 19 of the pipe system 15 which is open to the outside air.
  • the first and second coupling pieces 28, 29 are attached to each other by an elongate connecting element 31 extending in longitudinal direction of the first pipe segment 25.
  • the second and third coupling pieces 29, 30 are attached to each other via an elongate connecting element 32 extending in longitudinal direction of the second pipe segment 26, and extending from the third coupling piece 30 in longitudinal direction of the third pipe segment 27 in the direction of the roof 13 is a third elongate connecting element 33, which is attached to the roof.
  • the pipe system 15 thus consists here of a cascade of pipe segments 25, 26, 27 and coupling pieces 28, 29, 30 freely suspended in the flue gas discharge shaft 14, this in accordance with the non-prepublished Netherlands patent application filed simultaneously with the present patent application in the name of applicant with the title "Pipe system, coupling piece and method for installing the pipe system in a shaft of a building”.
  • Located on the ground floor 11 in the shown embodiment of the pipe system are two combustion devices 17, 18, such as a central heating boiler and/or a hot water appliance, the flue gas discharge of each of which are connected via a branch pipe or branch pipe part 20, 21 to the first coupling piece 28.
  • a single combustion device 16 which is connected via a branch pipe 22 to the third coupling piece 30.
  • No devices are connected to the second coupling piece 29.
  • This coupling piece functions solely for the purpose of connecting the first and second pipe parts 25, 26.
  • combustion devices 16, 17, 18 are all shown mounted at the same height, it should be understood that these devices and their branches 19, 20, 21 to a respective coupling piece 28, 30 on the various floor levels 11, 12 can be located at different heights.
  • the end 23 of the pipe system 15 can be connected to an outlet for discharging fluid collected in the pipe system 15, such as condensed water from flue gas to be discharged.
  • the pipe system 15 can of course also be applied in new building projects.
  • One or more of the combustion devices 16, 17, 18 can be provided with its own condensation outlet to, for instance, the sewer (not shown).

  • the first, second and third coupling pieces 28, 29, 30 may substantially each be of differing form. From the viewpoint of costs and convenience of mounting it is advantageous to couple the pipe segments to each other by means of a uniform coupling piece and to connect the various devices hereto via a uniform branch pipe part.

  • the attaching elements 37, 38 have in the shown embodiment a strip-like or strip-shaped receiving slot 39 extending in longitudinal direction of the coupling piece 30 for movably receiving therein and attaching a strip-like or strip-shaped connecting element 31, 32, 33.
  • the coupling piece 30 is provided, in its peripheral wall 36, with first and second opposite connecting openings 40, 41 for connection of a branch pipe 20, 21, 22 thereto.
  • the branch pipe 22 is connected via a self-positioning releasable screw coupling 42 to the connecting opening 40.
  • the coupling piece 30 is provided in its peripheral wall 36 with first and second opposite connecting openings 40, 41 for connection of a branch pipe 20, 21, 22 thereto.
  • the branch pipe 22 is connected via a self-positioning releasable screw coupling 42 to the connecting opening 40.
  • Figure 3 shows a cross-sectional view along the line III-III in figure 2 .
  • Both connecting openings 40, 41 are provided with a tubular flange 43 protruding a distance outward transversely of the peripheral wall 36 of the coupling piece 30 for connection of the branch pipe or branch pipe part 22.
  • an approximately U-shaped fluid collection channel 45 extending internally in the coupling piece 30 over a distance in radial direction around the peripheral wall 36 is situated at the bottom of the connecting openings 40, 41.
  • the open side 46 of the fluid collection channel faces toward the inlet end 34 of the coupling piece 30 (see figure 2 ) and connects here to the connecting openings 40, 41 for the purpose of collecting fluid moving during use along the peripheral wall 36 in the coupling piece 30 and the connecting openings 40, 41 or a branch pipe 22 connected hereto.
  • the closed base side 47 of the fluid collection channel 45 forms a stop for preventing a pipe element received in the coupling piece from the outlet end 35, such as the second pipe element 26 shown in figure 1 , from being able to block the connecting openings 40, 41.
  • ribs 48 protruding radially along the peripheral wall are formed internally in longitudinal direction of the coupling piece 30 at the position of the connecting openings 40, 41.
  • the fluid collection channel 45 debouches approximately in the form of a spout in the connecting openings 40, 41.
  • the spout-like part 49 extends internally along the wall of the flange 43 over a distance transversely of a connecting opening 40, 41, i.e. in axial direction of a branch pipe 22 to be connected to the flange 43.
  • the part 49 of the fluid collection channel 45 debouching in the connecting opening 40, 41 is provided with a fluid throughflow opening 50 which connects internally to the peripheral wall 36 of the coupling piece 30 via a fluid throughflow channel 51.

This achieves that collected fluid drains away in the first instance via a branch pipe 22 connected to the flange 43.
  • the bottom of the fluid throughflow channel or fluid return flow channel 51 inclines upward to some extent, i.e. upward as seen in the plane of the drawing, from the fluid throughflow opening 50 in the direction toward the peripheral wall 36 of the coupling piece.
  • This incline forms a fluid flow resistance with which the quantity of fluid flowing in the branch pipe and back into the coupling piece can be adjusted.
  • This flow resistance also achieves that, when for instance a connecting opening is closed, flow also occurs in the fluid collection channel 46 so that fluid residues do not accumulate herein.

  • the angle of inclination ⁇ relative to the normal to the outer periphery 36 of the coupling piece amounts in practice to about 3 degrees.
  • an effective barrier against condensation discharge via the branch pipe 22 can be brought about by selecting an internal diameter of the part of the branch pipe 22 not engaging on the flange 43 which is smaller than the internal diameter of the flange 43, so that the fluid collected in the fluid collection channel 46 flows via the fluid throughflow channel 51 back into the coupling piece 30.
  • the branch pipe 22 can of course be provided, with the same effect, with an internal radially protruding peripheral elevation 64 or the like which acts as barrier against condensation discharge via the branch pipe 22, as shown schematically with broken lines in figure 4 .

  • These nose-shaped members 53 are disposed opposite each other at a distance from the flange 43 adjacently thereof, with a connecting groove 54 facing toward the flange 43 for receiving therein a radially outward protruding connecting lip of a first end of the branch pipe 22 or the cover 44 to be arranged over the flange 43.
  • the radially outward protruding connecting lip 55 takes the form of a single helical revolving connecting lip along the outer periphery of the branch pipe 22 with a first end 61 and second end 62 lying opposite each other at a pitch distance s.
  • the pitch distance s of the helical revolving connecting lip 55 corresponds to the distance s between the outward protruding end 63 of the nose-shaped members 53 and the connecting groove 54 formed therein.
  • the helical progression of the connecting lip 55 forms together with the connecting grooves 54 a screw thread-like connection such that the force necessary to slide the branch pipe 22 over the sealing ring 52, which force can be relatively great because a highly fluid-tight seal can be envisaged, is generated from the screwing movement during connection of the branch pipe 22 to a coupling piece.
  • the branch pipe 22 is thus pulled over the sealing ring 52 by the relatively light force necessary for the screwing movement.
  • the positioning and pitch distance s of the single helical revolving connecting lip 55 and the corresponding distance s between the end 63 of the nose-shaped members 53 and their connecting grooves 54 facilitate a self-positioning screw coupling 42. That is, a branch pipe 22 to be connected can be placed initially with its revolving connecting lip 55 against the outer ends 63 of the nose-shaped members 53, wherein by subsequently rotating or screwing the branch pipe 22 to the right the revolving connecting lip 55 engages automatically in the connecting grooves 54, and by being rotated the branch pipe 22 can be screwed firmly onto the flange 43 in a second position of the branch pipe 22. By rotating an attached branch pipe 22 to the left back from the second position to the first position it can be uncoupled again and removed.
  • the revolving connecting lip 55 has close to the second end 62 a part 56 which takes a resilient form over a distance such that at the position of this resilient part 56 the pitch distance of the revolving connecting lip differs from the pitch distance s between the first and second ends 61, 62 of the revolving connecting lip 55.
  • This differing distance may be greater or smaller than the distance s.
  • this resilient part 56 forms a discernible indication that the branch pipe 22 has been screwed a sufficient distance over the flange 43, and also forms a barrier, in the form of a safety catch, against loosening of the branch pipe 22 due to vibrations or the like.
