Sleeve-shaped connecting link for pipe plug-in

end up

The invention relates to a sleeve-shaped connecting member For receiving the spigot ends of pipes at both ends, especially for installation lines.

When connecting pipe sections in installation lines, so-called double sleeves made of metal or plastic-coated metal are often used. Such double muffons are always straight. Even in the case of shorter pipes with a socket-type socket of this type, the socket-shaped expanded pipe section is always straight. The use of such straight double sleeves, however, always requires a straight pipe plug-in end. Particularly in the area of connections of sanitary objects or in the area of frequent pipe bends, this leads to construction dimensions, the planning and construction of connections of the pipe parts and sanitary objects very he bank account: Norddeutsche Landesbank, branch Bad Gandershelm, account no. 22,116,970 ■ Postal checking account: Hannover 667 15 «70

severe. Particularly in the case of compact installations, the straight line sections required can also Laying difficulties arise.

The invention is based on the object of a sleeve-shaped To create a connecting link of the type specified, the design of which also allows for the immediate introduction of curved pipe insertion ends, as well as the construction, planning and construction of line and property connections to simplify and facilitate, inshescndeie b-ii compact To fix installations and thus the disadvantage of previous constructions. This is done according to the invention basically achieved in that at least one tube receiving end of the link of the curvature of the. to be recorded Rohreinsteckendes is curved accordingly. This ensures that at least one of the receiving ends the connecting sleeve pipe bends can be inserted directly without straight ends. Not only does that result from this Advantage of less space requirements, but the additional advantage that curved pipe sections without straight Ends for one with the connecting links according to the invention To be created line can be used, so that the manufacturing costs in the manufacture of such lines suitable pipe sections and pipe bends, especially with automatic bending, significantly reduced and the hydraulic and fluidic values can be significantly improved. This is the case with walls and "ocken" and of particular importance in compact installations.

According to one embodiment of the invention, the connecting link is over its entire length corresponding to the pipe bend formed from the two pipe plug ends to be accommodated curved. Such a "design of the connecting member allows a direct connection of pipe bends together.

A particularly simple connecting link that is particularly lightweight and at the same time a simple one Allows assembly with high tightness of the connection, is achieved in a further embodiment of the invention that the Connecting member has a coating of sintered-on thermoplastic rubber inside and / or outside. One Inner coating made of thermoplastic rubber has the advantage that the outer diameter of the connecting link or the sleeve tube used as a connecting member is minimized because the usual sealing ring is omitted.

A particularly simple connecting link that is particularly lightweight and at the same time a simple one Allows assembly with high tightness of the connection, is achieved in a further embodiment of the invention that the The connecting member consists of an elastomer which can be heat-shrunk to form a seal on the pipe plug-in ends. The pipe plug-in ends are pushed into such a connecting link and it is then opened with a simple tool, e.g. heat tongs, a heat effect on the connecting sleeve exercised until the sealing and firmly shrunk onto the outer wall of the tube inserting ends and the connecting gap.

Further features, details and advantages of the invention emerge from the description of exemplary embodiments based on the drawing. The drawing shows a pipe section cut in half with three connecting links according to the invention.

As the drawing shows, for example, a pipe with two bends is to be composed of pipe sections. The line consists e.g. of two curved pipe bends 1 and 2 covering an angle of 45 °, the one Include connecting gap 3a, a straight pipe section with the connecting gap 4 and another, an angle of Curved pipe section 5 covering 45 ° with the connecting gap 6.

To connect these pipe sections 1, 2. 3 and '; te with each other to bridge the Verbindungssnal 3a, 4 and 6 are three connecting sleeves arranged according to the invention, the insertion ends of the curved pipe sections 1 and 2 are received by the connector sleeve 7, which at its (:. l ^Anzen; infe the male from the two pipe One enticing 1 and? formed pipe bend is correspondingly curved and covers the pre-binding gap 3a. The following pipe insertion probe dos / "" one receiving end is curved correspondingly to the curvature of the pipe plug-in end 2 to be received and runs straight at its other pipe receiving end corresponding to the straight pipe section 3. The connecting gap 4 is securely covered by the connecting sleeve 8.

In the further course of the line, the connecting sleeve 9 follows, on her the other insertion end of the straight pipe section 3 receiving end straight and on its following curved pipe section 5 receiving end of the curvature of this tube plug-in end 5 to be received is correspondingly curved. The connecting sleeve 9 securely covers the connecting gap 6.

The drawing clearly shows the simple form in which curved pipe sections can be connected to one another directly via the connecting sleeves according to the invention, while with the usual double sockets, the curved pipe sections always have a straight port setting as the pipe plug-in end require.

The connecting sleeves 7, 8 and 9 consist of inside and / or outside with sintered thermoplastic rubber coated metal, if required by the pipe made up of pipe sections 1, 2, 3 and 5. If it's the To enable use of the pipeline and the material of the pipe sections, the connecting sleeves 7, 8 are expediently made and 9 made of a plastic, in particular an elastomer,

the one on the respective pipe plug-in ends by the action of heat can be shrunk on in a sealing manner, namely by appropriate heating at the construction site, expediently by means of a so-called heat clamp.
