Definitions
- the invention relates to a device for the liquid-tight connection of a pipe with a flange sleeve or a flange pipe, the inner diameter of which corresponds at least to the outer diameter of the pipe and the flange has a front circumferential end face and a rear circumferential conical beveled surface, the pipe having one end in the inside of the flange sleeve or the flange tube is inserted and a sealing ring bears against the end face of the flange and the outer peripheral surface of the tube.
- pipe connections are usually designed as a socket connection, flange connection or clamp connection.
- welded, soldered or adhesive connections are known, but they can no longer be loosened subsequently! practice.
- flange connections between two pipes it is necessary for each pipe to have an end flange, which are connected to one another by fastening elements, for example screws, by inserting a seal between their end faces.
- fastening elements for example screws
- the inner diameter of the sleeve is somewhat larger than the outer diameter of the pipe to be inserted into the sleeve, so that although there is an easy connection option, these connections are very sensitive to tensile stress in the longitudinal direction of the pipes, since the connection can be easily released by pulling out the inner tube.
- there are leakage problems with this type of connection especially if the pipelines are subjected to higher pressures.
- the invention has for its object to provide a pipe connection between a pipe and a flange sleeve or a flange pipe, which is easy to manufacture and with a good sealing effect solve is.
- the sealing ring has on its side facing away from the end face of the flange a conically beveled surface, that the sealing ring by a clampable pipe clamp with a trapezoidal open cross section, the legs of which the conically beveled surface of the flange or the conically beveled surface partially overlap the sealing ring, can be pressed against the end face of the flange or the outer circumferential surface of the tube, and that the sealing ring is arranged in the interior of an angle ring which rests with its legs on the outer circumferential surface and the conically beveled surface of the sealing ring.
- a tensionable pipe clamp known per se with a trapezoidal open cross-section overlaps the conically tapered outer surfaces of the flange or the sealing ring, the sealing ring being arranged in the interior of an angle ring.
- the angular ring arranged between the limb of the pipe clamp and the bevelled surface of the sealing ring prevents the sealing material from migrating too strongly axially, so that the contact pressure acting in the radial direction on the outer circumferential surface of the pipe is not only sufficient to produce a good seal, but also an adequate fixation of the tube inside the Flange pipe or the flange sleeve is effected.
- the sealing ring can have an outer diameter that is approximately twice the wall thickness of the angle ring smaller than the outer diameter of the flange.
- the outer end edge of the sealing unit lies exactly on the height of the outer drainage surface of the flange.
- the legs of the angle ring only partially grip the corresponding sides of the sealing ring, so that there is enough space for the compression of the sealing material when the pipe clamp is contracted.
- the sealing ring In order to prevent the sealing ring from falling out of the angle ring during assembly, the sealing ring can be firmly connected to the angle ring by gluing or vulcanization.
- the sealing ring can have sealing lips running approximately parallel on its surface bearing against the outer circumferential surface of the tube. This increases the surface pressure in this area, so that the sealing effect is further improved.
- connection of a flange pipe 1 to a pipe 2 can be seen, a sealing ring 3 abutting against the end face 4 of the flange 5 and the outer circumferential surface 6 of the pipe 2.
- the sealing ring 3 has a conically beveled surface 7, which is opposite a conically beveled surface 8 of the flange 5! weighs.
- the sealing ring 3 is arranged in the interior of an angle ring 9, the upper leg 10 partially overlaps the outer circumferential surface 11 of the sealing ring 3 and the lateral leg 12 also partially overlaps the conically tapered surface 7 of the sealing ring.
- an inclined inclined surface 16 is formed, in which the sealing ring 3 engages with a nose 17. This not only facilitates a precisely fitting insertion of the sealing ring 3, it also prevents the sealing material from migrating radially. In the same way, the legs 10 and 12 prevent radial or axial migration of the sealing material.
- the tensionable pipe clamp 13 has a trapezoidal insert 18 over which a tensioning band 19 runs.
- the tensioning band 19 is pulled together in a known manner by the tensioning element 15.
- sealing lips 20 can be seen, which rest on the outer circumferential surface 6 of the tube 2 and allow increased surface pressure.

Abstract
Pour permettre un raccordement étanche aux liquides entre un tuyau à bride (1) et un tuyau (2), une bague d'étanchéité (3) à surface conique (7) est disposée à l'intérieur d'un cône de serrage (9). Pour obtenir un raccordement étanche aux liquides qui empêche le matériau d'étanchéité de s'échapper radialement ou axialement, et pour garantir que le tuyau (2) est solidement calé dans le tuyau à bride (1), on monte un collier de serrage (13) dont la branche trapézoïdale (14) s'emboîte sur une surface conique (8) de la bride (5) et sur la surface conique (7) de la bague d'étanchéité (3).
