Definitions

  • the invention relates to a pipe distributor for heating systems, the interior of which is preferably divided into a supply and a return chamber by a partition and has the connecting piece for the connection of supply and return lines.
  • pipe distributors are used to distribute the heat transfer medium to different heating circuits.
  • Such a pipe distributor is known from DE-OS 3 006 784.
  • This known pipe distributor has several connecting pieces arranged side by side, which lead alternately to the flow chamber and the return chamber. Two adjacent connecting pieces, one of which leads to the flow chamber and the other to the return chamber, form a heating group.
  • the required number of heating groups results from the number of heating circuits that are to be connected to the pipe distributor.
  • Pipe distributors with eight or more connection groups are quite common and have a correspondingly large length.
  • the invention has for its object to provide a pipe distributor which has a smaller length expansion with the same number of heating groups.
  • a particularly simple construction for the pipe distributor is obtained by dividing the housing of the pipe distributor on the inside by a horizontal partition into the flow and return chambers; that the inner connecting pieces are inserted vertically into openings in the partition and are led out of the housing through larger housing openings into which the outer connecting pieces are inserted.
  • the partition should be arranged so that the inner connecting pieces have a sufficient length so that they can be moved within certain limits at their ends. This mobility namely makes the connection of fittings or double pipelines considerably easier, since small manufacturing tolerances can be compensated for by simply moving the ends that are brought out.
  • a preferred embodiment of the invention provides that the inner connection piece is led further out of the housing than the outer connection piece.
  • the lead-out end of the inner connecting piece is preferably provided with at least one circumferential sealing ring and can be conical in shape.
  • a fitting to be connected or an inner tube can then be attached in a self-sealing manner to the inner connecting piece.
  • At least one of the two connecting pieces of a double connecting piece has a thread or a flange at the end led out of the housing.
  • the inner connecting pieces are in particular designed such that they are connected to the pipe distributor only at their distributor end and are at least twice as long as their diameter. In this way, a certain degree of mobility is obtained for these connecting pieces, which considerably simplifies the assembly of devices to be connected. It is particularly advantageous to design the inner connecting piece as a thin-walled brass tube, whereas the rest of the tube distributor can be made from sheet steel. In this connection, it is pointed out that the pressure of the heating medium inside and outside the inner connection piece is essentially the same, which is why this connection piece can be made more thin-walled than the outer connection piece.
  • the pipe distributor according to the invention shown in Fig. 1 is partially drawn in section.
  • the housing 1 of the pipe distributor is divided on the inside by a partition 2 into a flow chamber 3 and a return chamber 4.
  • the outer connecting piece 8 can each be provided with an external thread section 9 or with a flange 15. Pipes or shut-off elements 11 can be screwed onto the pipe distributor by means of a screw 10.
  • the tubes can consist of an outer tube and an inner tube, which are simultaneously fastened to the tube distributor by means of a screw 10.
  • the connecting pieces 6, 8 can also be soldered or welded to pipes to be connected.
  • shut-off devices designed as double valves can be arranged between these and the associated double connecting piece, with which the connected lines can be closed or opened at the same time.
  • One of the two inner connecting pieces 6 has at its end 12 led out of the housing 1 a flange 13, which offers an enlarged contact surface for a sealing ring.
  • the led out ends 14 of the outer connecting piece 8 may also have a flange 15 which holds a union nut 16 on the connecting piece 8. 2 shows such an arrangement with a union nut 16.
  • the inner connecting piece 6 are preferably passed so far through the outer connecting piece 8 that their end 20 protrudes beyond the end 14 of the associated outer connecting piece.
  • the end 20 is provided with a sealing ring 21. 1 shows part of a fitting 22 to be connected, the inner tube 23 of which is attached to the inner connecting piece 6.
  • the sealing ring 21 seals the flow against the return.
  • the valve 22 only needs to be attached to the connecting piece 8 with a union nut 16 and a sealing washer 24.
  • Fig. 1 shows a concentric arrangement of the inner connecting piece and a fitting 22 which has a correspondingly concentrically arranged inner tube 23. Due to manufacturing tolerances, inner tube 23 and connecting piece 6 cannot always be arranged exactly concentrically, which is why the inner connecting piece 6 has a certain elasticity so that it can always be moved into the position of the inner tube 23.
  • the inner connecting piece 6 is made as a thin-walled brass tube, which can absorb the bending stresses caused by moving the outer end 20.
  • the end 20 can be conical.
  • Fig. 3 shows an asymmetrical arrangement of the two associated connecting pieces 6, 8. This arrangement can be advantageous, for example, if double pipes with an asymmetrical inner pipe are to be connected.
  • a cover plate 17 can be attached, which has holes 18, 19, of which one hole 18 leads into the inner connection piece 6 and the other hole 19 into the outer connection piece 8.
  • the cover plate 17 can also be designed as a seal.
  • inner connecting pieces 6 are preferably fastened in the openings 5 by means of press fits.
  • the outer connecting pieces 8 can also be held by means of press fits, but they can also be soldered or welded to the housing 1 in order to increase the mechanical stability.
