Definitions

  • the present invention relates to a heat-shrinkable sleeve for connecting pipes and cables.
  • connecting sleeves are required to wrap the connective positions of oil pipes, gas pipes, or many kinds of cables in order to protect those positions from water, moisture, distructing actions by insects or animals, or from chemical materials.
  • Such connecting sleeves are made of synthetic fiber materials or base materials of polymer which tend to be shrinked by heating.
  • the present invention has been made by way of the process such as wrapping a sealing member doubly with both ends of the sleeve and joining a C-type channel thereto, which brings forth complete sealing effect together with strong combination and results in a thorough protection of the inner side of the heat-shrinkable sleeve by holding off air, water, moisture and other invasions from outside.
  • rails 12 are formed at both ends of a sleeve 11 in a heat -shrinkable sleeve 11 being made and a C-type channel is joined to the rails 12, as shown in Fig.3.
  • Another design is that both ends of a.sleeve 21 are bent symmetrically to form hollow rails 22, into which a sealing member 24 is inserted, and then a C-type channel is joined to both the rails 22 to connect and attach the sleeve, as shown in Eig.4.
  • each position of the rails is shrinked not so constantly(i.e. contraction ratios are not constant based on thickness and width of the rails) that gaps can be left not only between two rails 12 but also between each end of the C-type channel and the rails 12.
  • the present invention has been made in view of the above -described problems of the prior art and an object of the invention is to provide a method for complete sealing and combining of a sleeve in which outside substances such as air, water, etc. can be entirely excluded.
  • the object mentioned above can be accomplished by providing a method comprising: making hollow rails of the ends of a sleeve; inserting a sealing member into the one of the hollow rails which is smaller than the other; wrapping the hollow rail including the sealing member in the other one; and joining a C-type channel thereto, thereby allowing the ends of the sleeve to be sealed.
  • Fig.l is a side view a sleeve according to the present invention.
  • Fig.2 is a side view showing the combined form of a sleeve according to the present invention.
  • Figs.3 and 4 are side views showing the combined forms of the known sleeves.
  • the heat-shrinkable sleeve 1 as shown in Fig.l is wrapped around the connective outer surface of a cable or a pipe 6 which is subject to being sealed and connected.
  • the former Upon pressing the hollow rail 3 toward the other hollow rail 2 combined with a sealing member 4, the former is joined to the latter as the open space of the former becomes wide.
  • the C-type channel 5 is fitted to the outer surface of the hollow rail 3, the preliminary steps for sealing and connecting are finished, as shown in Eig.2.
  • the hollow rail 3 formed integrally with the sleeve 1 is shrinked and the other hollow rail 2 pressed on the sealing member 4 is the same, and thus the first becomes pressed on the second.
  • hollow rails 2, 3 decrease in length, they occupy inner space of C-type channel 5 and, at the same time, one end of hollow rail 2 and that of hollow rail 3 adhere closely to inner surface and outer surface of sleeve 1, respectively and thus sealing for binding together is finished hereby.
  • thermosensitive adhesives such as hot melts
  • the thermosensitive adhesives to inner surface of hollow rail 3 are thermally melt and sticked to the outer surface of hollow rail 2 and thus the adhesion of both the hollow rails 2, 3 becomes stronger.
  • sealing member 4 serves as a wedge even after shrinking, that is, since hollow rails 2, 3 are pressed with occupying the space between C-type channel 5 and sealing member 4, C-type channel does not come off hollow rail 3.
  • the present invention has been made for the purpose not only of preventing a gap in a combining position by shrinking and attaching doubly hollow rails and thus excluding external substances but of maintaining complete sealing of the space between C-type channel and sealing member as the twofold hollow rails are pressed and bound tightly therein.

Abstract

Procédé d'étanchéification et d'intégration totales d'une gaine (1), selon lequel on plie les deux extrémités d'une gaine (1) pour former des rails creux (2, 3) dont l'un (2) est associé à un élément d'étanchéité (4) tandis que l'autre (3), plus grand, s'associe audit rail (2) pour former un rail double entrant en prise avec un profilé en C. Enfin, on réalise, par thermorétraction, l'étanchéification et l'intégration totales de la gaine (1).
