Definitions

  • the invention relates to a device for tightly con ⁇ necting two mutually opposite pipe ends.
  • the invention has for its object to provide a device with which the pipe ends can be tightly connected, irre ⁇ spective of the material from which the pipes are manu ⁇ factured.
  • the device according to the invention is distinguished by a socket sleeve connected at one end, a tubular insert connected at the other pipe end and receiving the socket sleeve, wherein the tubular insert and the socket sleeve each have a flanged edge fixedly connected thereto which in mounted situation are mutually abutting, a divided U-shaped ring arranged round the flanged edge periphery and an element holding togeth- er the ring parts.
  • the pipes only have to be provided in this embodi ⁇ ment with a socket sleeve on one side and a tubular insert on the other side which are fixed to the head end of the pipe by means of for instance a butt weld.
  • the join is effected by sliding together the socket sleeve and the tubular insert, wherein sealing means can option ⁇ ally be arranged.
  • the mutually abutting flanges provide in the mounted situation a definitive fixing in axial direction, which can be brought about easily owing to the divided U-shaped ring.
  • the device is dis ⁇ tinguished in that a socket sleeve is connected in each case to the head end of a pipe for joining, wherein each socket sleeve has a flanged edge, which edges abut mutu- ally in the mounted situation, and a divided U-shaped ring is arranged round the flanged edge periphery, around which ring an element holding together the ring parts is placed and wherein a connecting insert is inserted into the socket sleeves.
  • the ends of the pipes are each provided with a socket sleeve and use is made of an insert piece for placing in the socket sleeve. The con ⁇ nection between the sleeves again takes place by means of the flanged edge and the divided annular parts arranged therearound.
  • both ring parts of the holding element are enclosed by a second ring, whereby these can be assembled in simple manner.
  • the socket sleeve and the tubular insert are prefer- ably manufactured of HDPE plastic which ensures a consid ⁇ erable tightness.
  • fig. 1 shows a perspective view of the device ac ⁇ cording to the invention with partly broken away parts
  • fig. 2 shows a lengthwise view, partly in section, of a second embodiment wherein each pipe end is provided with a socket sleeve.
  • the device consists of a tubular insert 4 connected to the pipe end 1, the outer periphery of this tubular insert being such that it fits into a socket sleeve 5 fixed to the right-hand pipe end 2.
  • the length of the internal space of the socket sleeve 5 takes up the whole length of tubular insert 4.
  • the socket sleeve is embodied with a flange 6 between the pipe end 1 and the tubular insert 4, wherein the free edge of the socket sleeve 5 is likewise provided with a protruding flanged edge 7. In a mounted situation both flanges lie with their end surfac ⁇ es mutually abutting.
  • an annular chan ⁇ nel 8 in which can be received a sealing means in the form of a rubber sealing ring 9.
  • a first ring 10 is arranged which consists of at least two parts. The separating surfaces 11 of these separate annular parts lie against each other and form a closed ring which must however by held in place by a holding element, here in the form of a second ring 12, the inner periphery of which fits closely onto the outer periphery of the first ring 10.
  • An annular channel 14 is recessed onto the separating surface 13 between the first and second ring 10, 12, this such that a flexible element in the form of a wire 15 can be carried therethrough via an axially extending opening to the outside in the ring 12.
  • the assembly of the device therefore takes place as follows.
  • the pipe is made suitable for joining by butt- welding the tubular insert 4 respectively the socket sleeve 5 against the head end of the pipe 1 respectively 2.
  • the tubular insert 4 is then inserted into the socket sleeve 5 until the flanges 6, 7 are mutually abutting.
  • the annular parts 10 are subsequently laid round the outer periphery of flanges 6, 7 such that the channel recessed therein comes to lie with the side walls thereof against the head ends of flanges 6, 7.
  • An axial displacement of flanges 6, 7 respectively the tubular insert 4 and socket sleeve 5 is hereby prevented.
  • the integral ring 12, which is pre-arranged round one of the pipe ends, is subsequently pushed back as far as the composite ring 10, whereby the parts thereof can no longer fall apart.
  • each pipe end 2 is connected to a socket sleeve 5, which connection can take place in any suitable manner, for instance with a weld 2' .
  • Each nor- mandy is embodied on the end remote from the pipe with a flanged edge 7 which have the same diameter and thick ⁇ ness.
  • a connecting insert 4' the length of which equals a maximum of twice the internal length dimension of the socket sleeve 5. It is herewith possible to slide the sleeves 5 fully over the insert 4' and to place the head ends of the flanged edges 7 in mutual contact.
  • the flanged edges 7 are mutually connected by means of the divided ring 10, the second ring 12 for arranging therearound which is locked in axial sense by the channel part 14 formed between both rings with flexible element 15 placed therein.

Abstract

Dispositif de raccordement étanche des extrémités (1, 2) de deux tuyaux situées l'une en face de l'autre. Le dispositif comporte un élément femelle (5) relié à l'extrémité (2) d'un des tuyaux, un élément mâle tubulaire (4) relié à l'autre extrémité (1) de l'autre tuyau et reçu dans l'élément femelle (5), à la fois l'élément mâle tubulaire (4) et l'élément femelle (5) étant pourvus d'un bord bridé (6, 7) solidaire de l'élément respectif, et ces bords bridés étant destinés à buter l'un contre l'autre en position d'assemblage, un anneau divisé en U (10) s'étendant autour de la périphérie des bords bridés, et un élément (15) destiné à solidariser les pièces de l'anneau (10) de sorte que le montage et le démontage sont très simples, et que tout moyen auxiliaire supplémentaire devient superflu.
