The invention relates to a heating circuit distributor, in particular for underfloor heating with a closed or draining heating medium receiving hollow body, one for each of the supply and return lines of the heating circuits screwed in armature or fitting.

Heating circuit distributors have the task of connecting the various heating circuits in parallel and connecting them to the relevant ones Inlet or outlet of the heater or a line

to connect the heater. The invention relates in particular on hot water heating systems such as those used for underfloor heating. In these In some cases, the heating circuit distributors are arranged either on one floor or in the basement and there depending on the local conditions on rising or horizontal Fastened surfaces. Usually one of the heating circuit distributors carries the valves that shut off and opening the heating circuits are used, while the other heating circuit manifold is used for the fittings for the pipelines the heating circuits. While these two heating circuit distributors are often used in single-family houses larger heating systems can also have several Make heating circuit distributor necessary.

In known heating circuit distributors, the hollow body consists of a pipe section. Because of the overview-11 clic j. cxx A-LUJAiiiiu-ug <iti.L "Fit Lings or Armaxures weraen Usually square pipes are used for the heating circuit manifold. For attaching the fittings or armatures holes are made in the pipe wall. Threaded sockets are inserted into these holes, which are located on the edge the hole to be soldered. Pipe clamps are used to attach such heating circuit distributors.

It is disadvantageous that leaks often show up in the soldering of the sleeves, which are difficult or cannot be eliminated afterwards at all. In addition, the drilling of the pipes is a relative one

7625947 03/10/77

difficult and comparatively expensive work ·. The sleeves used also have the disadvantage that the later fittings or armatures protrude quite far beyond the surface of the heating circuit distributor, so that difficulties can arise when attaching the heating circuit distributor.

C It must be possible to attach this in such a way that the

There are essentially three different types of attachment to be implemented: In the case of a rising V / and, the heating circuit distributor must be able to be attached in three positions, namely in such a way that the fittings or armatures point upwards, downwards or forwards. In the basement, it must be possible to attach the heating circuit distributor to a rising wall on the front side. In addition, it must be possible to mount two heating circuit distributors in a niche in such a way that the heating circuit distributors arranged one above the other do not interfere with each other with their armatures or fittings; e.g. this arrangement can be

The sealing of the armatures or fittings in the punched holes is special simply because by pressing the material is deformed inwards, which leads to a groove, in which the sight rings can be inserted. The time-consuming sealing with hemp and paste is no longer necessary. the fittings can easily be changed at any time.

The heating circuit distributor designed in this way can be implemented with flat outer surfaces »This makes it easier the orientation of the fittings or

Preferably and according to a further feature of the invention, the hollow body has a polygonal cross section composed of two sections, one of which on its long sides inside the hollow body arranged contact surfaces forming parts, frontal closures of the hollow body forming has further parts and the punchings, while a second section is attached to the outside of the hollow body Has parts forming contact surfaces.

This two-part design of the heating circuit distributor is particularly suitable for square to rectangular heating circuit distributor cross-sections.

7625947 03/10/77

Preferably and according to a further feature of the invention, diagonally arranged recesses with thread for a venting nozzle and a filling valve are provided on such a heating circuit divider on one of the end faces of the hollow body, and on the opposite side there is a recess for the fitting of the inlet and outlet line of the heating medium or a fitting arranged in the relevant line. In particular, the attachment of the vent and filling valves in these heating circuit distributors means a significant advance, because such fittings än so far ^; the known heating circuit distributors would be difficult or impossible to attach, and because of the diagonal arrangement with any normal position of the distributor, one connector is always on top (ventilation) and one connector is below (drainage).

It is preferable to save material by having the forms different sections of the hollow body with different wall thicknesses.

For this purpose it is provided that the first section

consists of a sheet metal blank, which has parallel folded edges on its long sides, between which the Punched-out areas are arranged and a plurality of further folded edges which run at an angle to this and which at am End of cutouts arranged at the edge of the blank.

This sheet metal blank can be folded down relatively easily and then forms a U-shape Section in two levels that can be accommodated in the second section. Since you are in this first section has accommodated all the punchings, you can see the second section, the also consists of a sheet metal blank, run relatively thin-walled.

To make it easier to attach, you can see his in a heating circuit distributor with a square outline Cross-section of three fastening means at an angle to one another before. Therefore, in one embodiment of the invention, the second section is off which the hollow body consists, provided with folded edges, which run parallel to its transverse sides. This are used to fold brackets for walls or ceiling brackets for on-site fastening of the hollow body.

The details, further features and other advantages of the invention will emerge from the following Description of an embodiment with reference to the figures in the drawing; show it

The heating circuit distributor shown as a whole in FIG. 7 according to the exemplary embodiment is for Underfloor heating determined. It consists of a hollow body, generally designated 1, which according to FIG the illustrated embodiment for the return lines has several fittings 2, wtiche on the side marked 4 of the heating circuit distributor 3 are screwed in. In addition, the heating circuit distributor has two connection options on its end face 5 6 or 7 »those for a not shown

? 6? 5947 03/10/77

Filling valve and one also not shown Ventilation are provided. There is a line valve on the opposite end 8th.

The hollow body 1 is divided in its longitudinal direction and consists of several; nested sections 9 or 10. Accordingly, the hollow body 1 is designed in two parts. First of all, the Section 9 described in more detail, which is shown in Figs.

O '' ■

This section consists of a sheet metal blank drawn in FIG. 1, which on its two long sides 12, 13 has two parallel folded edges 14, 15. There are several cutouts between the folded edges 15a, which are used to attach the fittings 2 explained in more detail below. The punchings 6 and 7 have already been explained. The punching is used to attach the line valve. Every struggle takes place in such a way that flaps C form in the punching direction, which ge in the heating circuit distributor 1 inwards

are directed. The tabs 19 are used to attach an internal thread 20 into which the external thread provided part 21 of the fitting 2 can be screwed in. The fitting in question has a flange 22. Between the underside 23 of the flange 22, which is stepped outwards at 24, and a groove 25, which occurs when making the relevant punching

7625947 ic.03.77

forms by itself, an O-ring is inserted, which is denoted by 26. In this way a completely tight connection of the fittings 2 achieved. Corresponding arrangements are at the punchings 6 and 7 and / or. 17 provided.

The sheet metal blank of the part 9 also has a plurality of folded edges 27, 28 and 29, 30, which are used for training of frontal tabs 31 or 32 or the End faces 5 and 33 of the heating circuit distributor are used. These transverse folded edges are in each case Cutouts 34, which start from the edge and have the shape of an equilateral triangle, the base line of which lies in the extension of the sheet metal edge.

The sheet metal blank is folded in one direction along the fold edges described. Through this the section 9 shown in FIG. 2 is produced, which is U-shaped in the longitudinal and transverse directions.

The corresponding part 10 shown in FIG. 5 arises from the sheet metal blank shown in FIG. 4, which is generally designated by 35 there. This sheet metal blank has two in its longitudinal direction running ialzkanten 36 and 37 as well as in the transverse direction running folded edges 38 and 39, respectively. Incisions 40 and 42, 43 extend from the transverse edges to the folded edges 38 and 39, respectively. Cutouts 44 and 45 are in each Tabs 46-48 or 49-51 provided through the

7625947 03/10/77

Incisions is formed. This creates the holder formed by the tabs, with which the heating circuit distributor 1 can be attached, which will be explained in more detail below.

The two described by edging the sheet metal cuts resulting sections 9 and 10 are plugged into each other, like the. ^ ig. 7 reveals. The contact surfaces are dimensioned so that there is a gap that is no larger than approx. 0.3mm. This creates a capillary effect, like hot solder between the contact surfaces Eight, for soldering, the solder is in the cold state on the edges between two touching surfaces applied, then the hollow body is placed in a soldering furnace. In this there is a reduced one Sphere and a temperature which melts the solder, which is now between aie -tserunruDgsilaciiei and the soldering of the two parts 9 and 10 causes. The reducing sphere in the furnace also causes a Desired removal of oxide layers so that the hollow body leaves the furnace bare.

Since the sheet metal blank of the section 9 has all the punchings, it can be made of thicker Produce sheet metal as the blank 35 for the part 10. This can save on material.

The fastening is done with the help of the tabs 46 »48, only one of the flaps is required at a time, see above
