Gegenstand der Neuerung ist eine Muffenverbindung für.' innen mit Kunststoff ausgekleidete Stahlrohre.The object of the innovation is a socket connection for. ' Inside steel pipes lined with plastic.
Bei bekannten Muffenverbindungen wurden innen mit Kunststoff ausgekleidete Muffen verwendet, in die beidseitig die vom Mantelrohr vorragende Kunststoffauskleidung hineinragte. Die Muffe selbst mußte mit einem Innenbund.-. versehen werden, damit ■ die Mantelrohre Anlage finden konnten. Nachteilig bei den bisher bekannten Verbindungen ist, daß kein glatt durchlaufender Strömungsquerschnitt vorhanden war; ferner waren die aus den Mantelrohren vorragenden Kunststoffrohrenden sehr anfällig für Beschädigungen bei Lagerung und Transport. Ein weiterer Nachteil ist, daß die Dichtung zwischen dem vorragenden Kunststoffrohrende und der Muffenauskleidung ein Hinterwandern des Transportmediums nicht vollständig verhindern kann..In known socket connections, the inside was made of plastic lined sleeves are used, in which both sides of the Jacket pipe protruding plastic lining protruded into it. the The socket itself had to be fitted with an inner collar. be provided so that ■ the jacket pipes could find facility. The disadvantage of the connections known up to now is that there is no smooth passage Flow cross-section was present; also were those from the Jacket pipes protruding plastic pipe ends very susceptible to Damage during storage and transport. Another disadvantage is that the seal between the protruding plastic pipe end and the transport medium migrates behind the sleeve liner can not completely prevent ..
Aufgabe der Neuerung ist eine Muffenverbindung, die. durch einfaches Zusammenschrauben einer normalen Muffe auf die^ Rohrenden von innen mit Kunststoff ausgekleideten.Rohren eine dichte, den Strömungsquerschnitt nicht verändernde: Verbindung herstellt.The task of the innovation is a socket connection that. by simple Screw together a normal socket on the ^ pipe ends The pipes are lined with plastic on the inside. that does not change the flow cross-section: Establishes a connection.
Neuerungsgemäß wird vorgeschlagen, die-Kunststoffauskleidung der Rohrenden von außen nach innen flaehkonisch auszudrehen,- und ein entsprechend konisches, ringförmiges Gegenstück, welches vor dem Verschrauben an den konischen Flächen mit einem geeigneten Kunststoffkleber versehen wird, einzusetzen. Durch die neuerungsgemäße Muffenverbindung wird der Strömungsquerschnitt nicht verändert. Die Enden der Mantelrohre aus Stahl liegen fest aneinander und verhindern ein Verquetschen des Diehtringes.According to the innovation it is proposed that the plastic lining to twist out the tube ends from the outside to the inside flaehonisch, - and a correspondingly conical, ring-shaped counterpart, which before screwing to the conical surfaces with a suitable plastic adhesive is provided. Due to the socket connection according to the innovation, the flow cross-section not changed. The ends of the steel casing pipes are tight against each other and prevent the Diehtringes.

In der beigefügten Zeichnung ist eine neuerungsgemäße Muffenverbindung im Schnitt dargestellt. In the accompanying drawing, a socket connection according to the invention is shown in section.
Die mit Kunststoffrohren (l und 2) ausgekleideten Mantelrohre (3 und 4) werden durch die mit normalem oder mit Rechts- und Linksgewinde versehene Muffe (5) zusammengeschraubt, nachdem, ein außen flachkonisch ausgebildeter Dichtring (6) in die innen entsprechend konisch ausgearbeiteten Kunststoffauskleidüngen (7 und 8) der Rohrenden eingesetzt wurde.. Wenn die Muffe (5) bis zum Aneinanderliegen der Mantelrohr enden angezogen ist., liegt der Dichtring (6) genau an den konischen Flächen (7 und 8) der Innenauskleidung an.The jacket pipes lined with plastic pipes (1 and 2) (3 and 4) are replaced by the with normal or with right and Left-hand threaded sleeve (5) screwed together, after which a sealing ring (6) with a flat conical shape on the outside is inserted into the plastic lining, which is correspondingly conical on the inside (7 and 8) of the pipe ends was inserted .. If the socket (5) is tightened until the jacket pipe ends are in contact., the sealing ring (6) lies exactly on the conical surfaces (7 and 8) the inner lining.
