Definitions

  • the invention relates to a pipeline having two fixedly connected in a solderless connection pipe sections or with a pipe section which is firmly connected to a connection to a hose or other pipeline mediating tubular nipple or pipe socket, according to the features of the preamble of the claim.
  • a solid, non-detachable pipe connection is achieved in that in the firmly connected state of the pipe, the projection of the connection sleeve around the compression collar of the pipe socket is formed radially inwardly around that the pipe socket is not pulled out of the stepped bore of the connection sleeve, since the inner diameter of the supernatant now smaller than the outer diameter of the compression collar of the pipe socket.
  • the in the annular space between the compression collar of the pipe socket and the conical step of the stepped bore of the connection sleeve clamped or axially pressed sealing ring seals the pipe socket against the connection sleeve.
  • the sealing ring is pressed against the inclined annular surface of the conical step of the stepped bore of the connection sleeve.
  • the annular space lying obliquely to the pipe axis and receiving the sealing ring has no escape space when the sealing ring has become open due to media contact. There is thus the risk of destruction of the sealing ring. Due to the angles of the two annular space corners smaller than 90 °, the sealing ring is pressed into the resulting triangles and deformed there more than in an annular space with only right angles. The risk of a split extrusion is extremely high.
  • the sealing ring is forced through the pressure prevailing in the hydraulic line operating pressure in the gap of the components to be sealed. If the shear resistance of the sealing ring is insufficient, the sealing material migrates into the gap between the inner and outer part. Both components are subject to a manufacturing tolerance, so that at their junction depending on the tolerances of the components creates a gap. The sealing ring is there very soon extremely deformed and further destroyed. The case of the sealing body resulting plastic deformation is increasing with continuous pressurization. In the final stage it comes to the failure of the seal, as by the changed voltage distributions in the sealing body a sufficient sealing function is no longer guaranteed.
  • the invention has for its object to provide a solid and permanent pipe connection of the type described above, in which no screwing or thermal joining methods are necessary and an undefined compression of the Abdichtringes with the dangers of destruction of the Abdichtringes due to occurring gap extrusion is minimized.
  • the object is achieved in that the length of the region of the pipe socket between its front end and the compression collar is greater than the length of the second longitudinal section of the stepped bore, so that an annular space between the compression collar of the pipe socket and the shoulder formed between the second and third longitudinal section is, in which the sealing ring is defined axially defined unenclosed under axial clearance.
  • the sealing takes place only by a radial deformation of the Abdichtringes between the outer circumference of the nipple or pipe socket and the inner circumference of the undeformed third longitudinal portion of the connection sleeve.
  • the compression collar of the inserted pipe socket is arranged at a distance from the bottom of a stepped bore of the connection sleeve in the inserted state.
  • the O-shaped sealing ring is arranged so that no axial pressing forces act on this.
  • the sealing ring is merely tensioned radially and thus ensures the sealing effect.
  • the annular space receiving the sealing ring is formed by the compression collar and a shoulder of the stepped bore in the connection sleeve.
  • This arrangement has the advantage that the nipple or pipe socket is firmly and permanently connected to the connection sleeve, wherein the sealing ring experiences no gap extrusion.
  • the seat of the Abdichtringes has a symmetrical shape of an annular space.
  • both components After their connection, both components together create a defined symmetrical annular space which receives the sealing ring, which is pressed there only radially and the separation point radially seals these two components. The risk of leaks leading assembly errors is minimized.
  • the pipe socket undergoes no diameter reduction during pressing, a screw connection can be omitted. An elaborate groove in the bore of the connection sleeve for receiving a Abdichtringes is unnecessary.
  • Figure 1 is a connection point of a pipe in which in the end of a pipe section one end of a pipe socket is inserted, wherein the two parts are not yet firmly connected;
  • Fig. 2 shows the pipe connection of Figure 1 with firmly connected parts.
  • a connection point of a pipe 3 is shown, in which the ends of a pipe section 4 and a pipe socket 5 are inserted into one another.
  • a tubular nipple may be connected, which is configured at its other end for receiving a hose.
  • the pipe socket 5 has an upset, outwardly projecting compression collar 6, which is spaced from the front end 7 of the pipe socket 5.
  • the pipe section 4 has a connection sleeve 8, which is penetrated by a central stepped bore 9 coaxially.
  • the stepped bore 9 has a first longitudinal section with an inner diameter 11 which is smaller than the outer diameter 12 of the pipe socket 5.
  • the stepped bore 9 has a second longitudinal section with a second inner diameter 13, which is the outer diameter 12 of the pipe socket 5 corresponds and in which the pipe socket 5 is pushed. Is between the first and second length section by the diameter jump an annular shoulder 17 is present.
  • a third longitudinal section of the stepped bore 9 has an inner diameter 14 which is dimensioned such that the compression collar 6 of the pipe socket 5 fits into this inner diameter 14 in the circumference approximately adjacent to the bore inner wall of this longitudinal section.
  • annular shoulder 15 is provided by the diameter jump, which also forms an annular surface.
  • the compression collar 6 of the pipe socket 5 is in the inserted state shown spaced from the shoulder 15 of the connection sleeve 8, so that an annular space 10 is formed between the compression collar 6 of the pipe socket 5 and the shoulder 15, in which the sealing ring 18 is arranged axially unclamped under axial free space, ie the length of the annular space 10 is slightly larger than the width of the Abdichtringes 16th
  • connection sleeve 8 has at the free end on a projection 18 which projects beyond the compression collar 6 of the pipe socket 5 at fully inserted pipe socket 5.
  • Fig. 2 shows the pipe connection in a firmly connected state.
  • the projection 18 of the connection sleeve 8 is radially formed around the compression collar 6 of the pipe socket 5 in that the pipe socket 5 is not pulled out of the stepped bore 9 of the connection sleeve 8, since the inner diameter 21 of the supernatant 18 is now smaller than the outer diameter 22 of the compression collar 6 of the pipe socket 5.
  • the arranged in the annular space 10 between compression collar 6 of the pipe socket 5 and the shoulder 17 of the stepped bore 9 of the connecting sleeve 8 Abdichtring 16 is only radially clamped and seals the pipe socket 5 only radially against the connection sleeve 8 safely.

Abstract

L’invention concerne un assemblage de canalisation non détachable entre un manchon de raccordement tubulaire extérieur (8) et un embout intérieur (5) doté d’un collet de refoulement (6) inséré dans le manchon de raccordement (8), le manchon de raccordement (8) derrière le collet de refoulement (6) de l’embout (5) étant radialement déformé vers l’intérieur. De cette manière, l’embout (5) ne peut plus être extrait du manchon de raccordement (8). L’étanchéification s’effectue uniquement radialement grâce à une bague d’étanchéité (16) placée entre l’embout (5) et le manchon de raccordement (8).
