Definitions

  • Figures Ia to Id are several different views of a joint of the present invention for connecting two lengths of pipe, which comprises two opposite pipe unions, coassially joined in an intermediate area at the annular abutment shoulder that acts as a limit stop for the pipe on the corresponding unit.
  • Figures 2a to 2d are several different views of the pipe locking nut cooperating with a pipe union for locking a pipe end thereon .
  • Figure 3 is a sectional view as taken along a central plane parallel to the axis of the union of an enlarged detail of the pipe union .
  • the inner surface of the tabs 203 may either be smooth or have projections arranged over one or more circumferences or at different points of said surface to increase the crimping action exerted by the inner surface of the nut 3 on the outer surface of the pipe 2.
  • extension tabs 203 also form an extension of the threaded conical surface ⁇ on the inner side of the nut 3 , the internal threads
  • Figure 3a shows three tabs 203 the number of tabs 203 can change according to the diameters of the unions 1.
  • the joint opening condition i.e. when the pipe
  • the tabs 203 effectively increase the pull-out resistance of the joint.
  • the axial force in the pull-out direction of the pipe 2 causes the tabs 203 to bend and act as a clamp, thereby allowing the teeth and/or the projections to further penetrate the pipe 2. Therefore, the tabs 203 have an additional clamping effect as compared with similar joints, thanks to the action of the helical teeth and/or projections, and prove to be an important component for connection of the pipe 2 on the joint.

Abstract

La présente invention concerne un raccord de tuyau comprenant un raccord union tubulaire (1) pour l'extrémité d'un tuyau (2) qui est destinée à être introduite dans le raccord union tubulaire, ledit raccord union (1) présente une section cylindrique intermédiaire (101) avec une partie conique s'élargissant (201) au niveau de l'extrémité qui est conçue pour être emboîtée dans le tuyau (2). Un écrou (3) est fourni afin de verrouiller le tuyau (2) sur le raccord union (1), ledit écrou (3) présentant une surface intérieure conique, ladite surface conique s'élargissant vers l'extrémité et étant conçue afin d'être ajustée sur le raccord union (1). Le tuyau (2) est encastré entre la surface conique intérieure de l'écrou (3) et la surface conique extérieure au niveau de l'extrémité du raccord union (1) par le déplacement axial de l'écrou (3) vers la partie conique s'élargissant (201) au niveau de l'extrémité du raccord union (1). L'écrou (3) présente des filetages intérieurs (103) s'étendant le long de la section conique de l'écrou (3), ce qui fait que le verrouillage ou le serrage définitif du tuyau (2) sur le raccord union (1) peut avoir lieu.
