Damit füllt die Dichtung zunächst alle 004 921 beiderseits des Kunststoff-Dichtungsringes Unebenheiten aus, die an der Rohroberfläche oder dünnwandige, verformbare, etwa kegelsäumpfförmige auch in der Muffenringkammer vorhanden sein kön-Ringscheiben von etwas größerer Ringflächenbreite nen. Die metallischen Ringscheiben verpressen sichThe invention relates to a pipe connection sleeve think to create a permanent tight connection the mechanically secured clamp 50 fen. It has confirmed the assumption that it is on smooth end sections of small-caliber tubes made of steel the interaction of the between crimpable od. The like. Which in an axially tensionable arrangement Bewchrungsringscheibe enclosed art between an end wall within the socket and fabric sealing ring with those in the same socket Nut type ring chamber screwed to the end of the socket, guided, jamming-free, rear rings Pressure sleeve a deformable plastic seal 55 arranged on the same sleeve-like processing ring as well as a terminal caps next to the outer end face, of which the ausdes Sealing ring arranged hard, in the end of the mechanical jamming of the Knife about the same size spacer pressure ring with inner tube end serving rings of claws in the cone cone in a ring surrounding the pipe see bores of spacer pressure rings placed in front of it chamber and one with locking claws are exposed to the deformation one after the other, stretched, sleeve-like clamping cap next to the die between the special reinforcement ringschci-compression sleeve having, the claws by means of the ben enclosed plastic seal allows a Inner cone of the disiance pressure ring after clamping increase of your pressing without the possibility tion of the sealing ring in the outer surface of a pressure loss due to the drainage of synthetic pipe can be pressed in, according to the main patent 65 material mass. The seal initially fills them all 004 921 on both sides of the plastic sealing ring from unevenness on the pipe surface or thin-walled, deformable, approximately frustoconical rings can also be present in the socket ring chamber of a slightly larger ring surface width. The metallic ring disks are pressed together

Only after this good, permanent Only the Wreaths of claws due to the different hallmarks Deformation resistance ties brought into the clamping position.
Durch die Vielzahl der Krallen werden die mechanischen Klemmstellen in der Zahl vergrößert und die Oberfläche des Rohres weitestgehend schonend behandelt. Damit sind gute Voraussetzungen dafür geschaffen, daß die Verbindungen auch nach mehrmaligem Lösen immer wieder neu an den gleichen Rohrenden zuverlässig abgedichtet und festeeklemmt hergestellt werden können. Erneuert wircflediglich der Kunststoff-Dichtungsring einschließlich seiner Bewehrungsscheiben. Es sind gute, dichte und feste Verbindungen unter Aufwendun» normaler Drehmo- «icnic beim Einschrauben der Druckhülsen zu erzielen, und es ist ein Vorteil der Verbindung daß auf Crund des sehr dichten Erfassens der Rohrenden die Neiaung zum wiederholten Nachspannen der mecha-•ischen Klemmittel geringgehalten wird.Due to the large number of claws, the mechanical Terminal points increased in number and the surface of the pipe treated as gently as possible. This creates good conditions for the connections even after repeated Loosen again and again at the same pipe ends, reliably sealed and clamped can be produced. Really renewed the plastic sealing ring including its reinforcing washers. They are good, dense, and firm To achieve connections with the use of »normal torque« icnic when screwing in the pressure sleeves, and it is an advantage of the connection that the pipe ends be gripped very tightly Requirement for repeated re-tensioning of the mechanical • Clamping means is kept low.
In der Zeichnung ist die Rohrverbindungsmuffe einschließlich Rohrverbindung nach dem Verspanten veranschaulicht.In the drawing, the pipe connection socket including the pipe connection is shown after the trimming illustrated.

Zum Dichten und Festklemmen eines außenseit.g glatten Rohrendes dienen folgende, in der Ringkammer 13 zwischen einer inneren Kammerstirnwand 7 und einer mit dem Muffenende verschraubten mutterartigcn Druckhülse9 in axial verspannbarer Anordnung nach rückwärts gestaffelte Körper, und zwar ein verformbarer Kunststoff-Dichtungsring 6 — der zwischcn in unverformtem Zustand etwa kegelstumpfförmicen Ringscheiben 15 aus Stahl od. dgl. angeordnet ist —, ein harter Distanzdruckring 5 mit Innenkonus 10 und die mit in die Mantelfläche des Rohres eindrückbaren Sperrkrallen 14 versehene Klemmkappe 4, dahintcrgeschaltet ein weiterer Distanzdruckring 5' und eine Klemmkappe 4'.The following are used to seal and clamp a smooth tube end in the annular chamber 13 between an inner chamber end wall 7 and a nut-like screw screwed to the socket end Pressure sleeve9 in an axially tensionable arrangement to the rear staggered body, namely a deformable plastic sealing ring 6 - which is roughly frustoconical in the undeformed state Ring disks 15 made of steel or the like is arranged - a hard spacer pressure ring 5 with an inner cone 10 and the clamping cap provided with locking claws 14 which can be pressed into the outer surface of the pipe 4, followed by another spacer pressure ring 5 'and a clamping cap 4'.
Der Außendurchmesser beider Klemmkappen 4, 4' entspricht etwa dem Innendurchmesser der Ringkammer 13.

Wesentlich ist bei der Rohrverbindungsmuffe die Ausrüstung mit mehreren angleichen buchsenartigen Klemmkappen 4', deren Buchsenabschnitte stark profiliert sind, wobei an Stelle des zweiten Distanzdruckringcs 5' der Büchsenabschnitt der Klemmkappe 4 mit dem Innenkonus versehen sein *ann, Die beiden vorgesehenen angleichen Klemmkappen 4. 4' weisen einen unterschiedlichen Vertomungswiderstand auf, und zwar derart dali die Klemmkappe 4 mit dem geringeren Verformungswiderstand jeweils näher zum Dichtungsring 6 angeordnet ist als die Klemmkappe 4 mit dem höheren Vcrformungswidersland. Beim Einschrauben aer Druckhülse 9 wird der axiale Schub durch die Klemmkappen und Distanzdruckringe erst aut den Dichtungsring 6 weitergelebt und dieser zwischen seinen Ringscheiben 15 verpreßt. Ers dann vernegeln sich die Krallen der buchsenartigen Klemmkappe 4 im Rohrmantel. Zuletzt werden dann die Krallen der Klemmkappe 4 in den Rohrmantel eingepreßt. It is essential in the pipe connection socket equipment with multiple align receptacle terminal caps 4 ', the socket portions are strongly profiled, wherein instead of the second Distanzdruckringcs 5' bear the bushing section of the clamping cap 4 with the inner cone * ann, the two provided adjust terminal caps 4. 4 'have a different vertical resistance, namely in such a way that the clamping cap 4 with the lower deformation resistance is arranged closer to the sealing ring 6 than the clamping cap 4 with the higher resistance to deformation. When the pressure sleeve 9 is screwed in, the axial thrust through the clamping caps and spacer pressure rings is only continued into the sealing ring 6 and this is pressed between its annular disks 15. Then the claws of the socket-like clamping cap 4 in the pipe jacket are nailed up. Finally, the claws of the clamping cap 4 are then pressed into the pipe jacket.
