"Fitting for crossing and forwarding two, physically from each other in pipelines ■" separated without Loss of level of leading media streams "

The invention relates to a pipe shape piece. Fitting called which for Change of direction, branching or crossing of media flowing in pipe systems is used. The invention aims at improved shape of such fittings.

The crossing of two pipes, which usually carry different media, requires considerable space in the area of the intersection. This space is often not available when building a house, because with horizontally laid pipes every branch, for example in the flow and return of a heating system, means a loss of height of several cm. If such branches or crossings are repeated for reasons of line routing, the officially prescribed head height is often endangered. - _; ; \ ■

Making such junctions or crossings is time consuming and expensive. The manual work is often on ladders or scaffolding execute; Flaring tool for perfect expansion are not always available, so that 'often with the help of pliers a qualitatively poor connection is established. This connecting bend with its one-sided welding point inevitably causes a; Warping of the pipes, so that this point subsequently / with considerable expenditure of time, must be addressed.

For the bending of the connecting bends on the construction site, a pipe bracket and a welding device must also be available in the immediate vicinity be. Time-consuming journeys when transporting the devices are unavoidable, Not to mention the two workers required for bending. The visual appearance of the so-called overbows is pronounced bad.

The fittings developed so far for this purpose, for example after the Swiss patent 381 o3.o or the French patent 662 17ο, have the disadvantage »to only have screw connections that require precision during laying, which are used in the pipe assembly sector cannot be adhered to by reasonable means. A different fitting system, in which the straight media flow leads through the hollow core of a fitting housing at a conscious distance, is not applicable everywhere and its application is not necessary even if when pipe movements due to expansion as a result of warm media are not to be feared.

The invention has set itself the task of an improved Form of a fitting, in the case of intersecting media, which are shown To avoid disadvantages, to create a spatial shape that is not associated with any loss of height and both in sheet metal and cast construction is advantageous and easy to manufacture.

The invention is based on a device for cruising and Continuation of two media flows in pipelines without loss of level, physically separated from one another, in one fitting in which one of the media streams is divided into two parts to make the undivided ^ / a straight line and ausflies send media stream around, is guided, out and they know-

is characterized by the fact that around the straight pipe part, the connection openings for the two-part media flow are more load-bearing Ring, with side walls flanged at the ends, which form a positive fit connect to the outer wall of the straight pipe section, arranged and, forming an annular cavity, sealing is soldered, welded or glued to this.

Figure 1 shows a fitting according to the invention, designed as Sheet metal construction. The straight pipe part 1 is from a Enclosed ring 2, which has side walls 3 flanged at the ends. The side walls 3 adjoin the outer wall of the pipe part 1 in a form-fitting manner, which guides the undivided media flow in a straight line. This construction can be made by placing in the place where the crossing is to take place, the ring 2 "with the connection openings and the side walls 3 stripped over the pipe part 1 and fastened there in a sealing manner will. But you can also use the fitting with the inner pipe part 1 and ring 2 already welded and the four pipe connections e produce in the usual way. The visual indicators are marked with the number 6 marked.

Figures 2 to 4 show a fitting according to the invention in a cast construction with four connections for two media. In order to match the flow cross-sections in the crossing area as closely as possible to the cross-section of the pipelines and thus to avoid pressure losses as far as possible, but still enabling a compact design is straightforward running, i.e. crossed media flow inside the fitting in cross-section lenticularly drawn in width, as shown in the figures 3 and 4 clearly show. The intersecting, dividing media flow is divided by the outer wall of the pipe section 1 in such a way that it partly below, partly above the undivided, essentially straight line running stream runs through the fitting, after reaching the end of the crossing point in the sense of the flow direction again to unite into one stream.

Basically, see two media flows cross within the fittings according to the invention, which are or can be different in temperature and / or composition. The different relationships in the line routing of the previous system and of the system according to the invention are shown in FIGS. FIGS. 7 and 8 show the usual design with the significant loss of height due to the pipe bend 9, lo welded to the main line 7/8. Figures 9 and 10, but especially Figure 9, convincingly show that practically no loss of height occurs in the fitting 1, 6 according to the invention. \ \ \ - \ \. \ \ "/ ■

In the same type of representation are in Figures 11 to 13 the im; Principle with regard to the loss of space similar circumstances when using a double sheet 11, which, after the Kreuzurigsstelle, compensates for the loss of height, but has the same disadvantageous circumstances at the crossing point. In FIGS. 14 and 15 it is shown how, when using the fitting 6, any loss of height, even in the intersection area, is avoided. \ '. ·. ', ■

The tests showed a gain in time for each crossing point made with the fitting of the invention, of 12 minutes. The others The benefits are considerable. This means that the bending devices that were previously necessary are no longer necessary away. You save the thermal energy for bending and can .work with a minimum of tools. It is now possible the entire distribution line of a pipe system on one level embarrassed. The fitting can be used universally and in any position to be built in; the pipe system is now clear and adjacent Installations don't interfere with each other.

In pipeline construction, the fitting is the first step towards prefabrication, which so far, precisely because of the difficult connection and distribution problems; was considered impossible. '

With the fitting according to the invention is in all branches of industry that Use flowing media, an important means of. Compact design given. \, '
