Definitions

• the invention relates to a pipe fitting connection, in particular for sanitary and heating systems, and radiators and the like.
• the fitting is sealingly inserted into a pipe profile, for example a radiator header pipe, which consists of cold-flowable material, for example aluminum, and that Fitting is provided with at least one sealing ring, which bears sealingly on the inner jacket of the tubular profile, and on at least two opposing ones
• heating radiators are a particular area of application for the fitting connection according to the invention.
• heating radiators are formed from a link strand made of light metal profiles, which consists of a series of links with riser pipes for the heat exchange medium and essentially H-shaped exchange webs and collecting pipes arranged at the ends.
• the header pipes represent the pipe profile of the fitting connection.
• the object of the invention is primarily to provide a fitting connection which seals better than the conventional connections in which both the pipe section and the fitting are provided with a thread, the fitting being screwed into the pipe section and for sealing, for example, hemp is used.
• Another object of the invention is to provide a fitting connection that can be established quickly, in particular that no thread has to be screwed onto the part to be cut to length, which is of course the pipe section.
• connection irrelevant whether it is a so-called blind plug, vent plug or connection plug.
• fitting connection according to the invention is suitable for use with twin and triple connectors.
• the fitting is made of harder material than the tubular profile, and in that the tubular profile is pressed in a toothed manner to the profile with deformation.
• the profile piece is preferably pressed by means of hydraulic pliers, but can also be done mechanically with a suitable ratio, with which a pressing pressure of, for example, approximately 500 kg can be achieved.
• An advantageous embodiment of the invention provides that the profiling is formed by webs surrounding the fitting.
• profiling is formed by a web which. is designed in the manner of a Gewilideganges.
• This design makes the fitting reusable, i.e. it can be unscrewed from the pipe section after pressing, while it is only inserted into the pipe section during assembly and then pressed.
• two sealing rings are provided, which are located on both sides of the profiling.
• sealing ring If only one sealing ring is provided, it will be located between the location or locations with the profiling and the outer end of the tubular profile.
• the fitting is flattened in the area of the profiles.
• the pipe profile is advantageously pressed point by point.
• the fitting is made of steel and further that the tubular profile is made of drawn aluminum.
• the tubular profile made of drawn aluminum ensures a particularly clean seal of the O-ring.
• FIGS. 2 to 4 show schematic side views of a fitting connection according to the invention
• FIG. 5 also shows schematically a radiator, the vent plug or connector according to of the fitting connection according to the invention
• FIGS. 6 to 8 show exemplary embodiments of the profiling according to the invention.
• the fitting connection according to the invention is based on the described in Fig. 5 radiator.
• the radiator consists essentially of riser tubes, which are formed by longitudinal profiles 1 and manifolds, which are formed by tube profiles 2.
• the fitting connection according to the invention exists between a header pipe and a fitting 3.
• a fitting connection is described in which the fitting 3 is a blind plug.
• the fitting 3 is provided on its jacket over the width d with a profiling 4 which is formed by webs 5 which run around the fitting 3.
• the fitting 3 is provided with an annular groove 7 on each side of the profiling 4, 7 sealing rings 8 being arranged in the annular grooves.
• the fitting 3 is inserted into the tubular profile 2, which is preferably formed from drawn aluminum, whereupon the plugs from the direction of the arrows Rohxprof.il 2 is pressed at points 9 with a pair of pliers, not shown, so that it with the profiling 4 pressed at two opposite points of the tube profile 2.
• two pipe profiles 2 can be connected to one another.
• the assembly is carried out in accordance with the exemplary embodiment described above, of course the pipe profiles 2 are pressed on both sides of the fitting 3 in the region of the profiles 4.
• the implementation of a fitting 3 with only one sealing ring 8 is advantageous if the profiling 4 is designed as a thread and thus the fitting 3 is screwed out of the tubular profile 2 and in another pipe profile 2 can be pressed again. Characterized in that the sealing ring 8 is between the profile 4 and the outer end of the tubular profile 2, it is not damaged when unscrewing.
• FIG. 8 shows a fitting in which the profiles 4 are made only in places and the fitting 3 is flattened in the area of the profiles 4.
