Definitions

  • the invention relates to a pipe press connection according to the preamble of claim 1.
  • the press fretting has an annular bead in the end region in which a sealing ring can be inserted.
  • the pipe to be connected is pushed into the press fitting and the press fitting is pressed radially onto the inserted pipe by means of a two-jaw press tool.
  • the sealing ring pressed onto the tube forms the sealing level.
  • a press ring is pushed axially onto an approximately cylindrical coupling body, which is provided with at least one tooth element on at least the inner surface.
  • the toothed means dig into the outer surface of the inserted tube and form the sealing plane in double function and at the same time the axial securing against pushing out of the tube.
  • a disadvantage of the Lokring system is that a completely different tool is required for pressing and, secondly, considerably more space is required to be able to move the press ring axially.
  • the object of the invention is to use the advantages of the Lokri ⁇ g system for a Roh ⁇ ress connection, using the pressing tools in large quantities on the market for radial pressurization.
  • the press fitting element is provided on the inner surface with at least one tooth compound, which digs into the outer surface of the inserted tube when pressed.
  • an at least outwardly extending collar which engages in a recess of the respective press jaw during radial pressing.
  • a plurality of tooth materials arranged at a distance from one another form the sealing plane and at the same time the axial securing.
  • the double function of axial securing and tightness is supported by an inwardly extending part of the collar.
  • the height of the inward extension corresponds to the height of the dental compound.
  • the sealing plane is formed by assembly, while the tooth means takes over the function of the axial securing.
  • the inner diameter of the sealing means corresponding to the inner diameter of the Zahnm 'rttels.
  • FIG. 1 in longitudinal section a first embodiment of a Roh ⁇ ressthetic designed according to the invention

  • the press fitting element 1 can be part of an elbow, a T-piece, a reducer or the like.
  • the press fitting element is characterized by a cylindrical sleeve 2, which is provided with a total of four teeths 3 - 3 "'on the inner surface.
  • each press jaw 7, 7 ' has at least two pressing jaws 9, 9' and a recess 10 arranged in the middle area.
  • the collar 5 of the press-fitting element 1 engages in this recess 10 during radial pressing a, so that the sleeve relative to the axial assignment of Zahnm 'rtteln 3 - 3 '"to the press bars 9, 9' is centered.
  • the inwardly extending part of the collar 5, like the tooth mortars 3 - 3 '", assumes the function of securing, but mainly that of tightness.

Abstract

L'invention concerne un raccord de tuyaux emmanché à la presse, constitué d'un élément d'emmanchement à la presse métallique (1, 1', 12, 12') pratiquement cylindrique et d'un tuyau de conduite métallique (6) à paroi mince s'insérant dans cet élément, grâce auxquels est formé un raccord de tuyaux emmanché à la presse étanche et inamovible à l'aide d'un outil de compression pourvu d'au moins deux mâchoires (7, 7') et entourant l'élément d'emmanchement à la presse, et ce après mise en place et fermeture radiale. Selon l'invention, l'élément d'emmanchement à la presse comporte, sur sa surface interne, au moins une denture (3, 3') qui s'enfonce lors de la compression dans la surface externe (11) du tuyau de conduite inséré. Sur la surface externe de l'élément d'emmanchement à la presse se trouve une collerette (5) s'étendant au moins vers l'extérieur et s'engageant lors de la compression radiale dans un évidement de la mâchoire correspondante.
