Abstract

According to the invention, this device is characterised in that it comprises a rigid hub 1 blocked off at its inside by a plate 2 to which an expandable sleeve 3 judiciously reinforced by strong cables or fibres 6 is fixed at its ends in a sealed and mechanically strong fashion.

Description

La présente invention concerne les système d'obturation de canalisations, et plus particulièrement un type nouveau d'obturateur dilatable. The present invention relates to pipe shutter systems, and more particularly to a new type of expandable shutter.

L'obturation temporaire de canalisations est un problème fréquemment rencontré lors de travaux, de tests, ou d'autres cas. Le principe consistant à avenir gonfler une structure à l'intérieur de la canalisation jusqu'à obturation totale de celle-ci est bien connu. Les obturateurs dilatables permettent en outre l'obturation de canalisations de différents diamètres selon leur gamme de dilatabilité. Temporary plugging of pipes is a problem frequently encountered during work, tests, or other cases. The principle of inflating a structure inside the pipeline until it is completely blocked is well known. The expandable shutters also allow the sealing of pipes of different diameters according to their range of expansion.

Le matériel existant présente différents inconvénients qui viennent nuire à sa commodité, son efficacité, ou sa fiabilité. Entre autres citons ceux-ci - rémanence mécanique de l'enveloppe préjudiciable au passage d'un diamètre maxi à un diamètre mini - hétérogénéité des contraintes en les différents points de l'obturation. The existing equipment has various drawbacks which affect its convenience, its efficiency or its reliability. Among others, let us cite these - mechanical persistence of the envelope detrimental to the passage from a maximum diameter to a minimum diameter - heterogeneity of the stresses at the different points of the obturation.

- vulnérabilité des extrémités fragilisées par des moyeux mécaniques d'ancrages et par des dispositifs de gonflage et de passage.- Vulnerability of the weakened ends by mechanical anchoring hubs and by inflation and passage devices.

- volume à remplir relativement important pour les obturateurs de grande section.- relatively large volume to fill for large section shutters.

La présente invention a pour but de remédier à ces inconvénients. Elle concerne un dispositif d'obturation de canalisations composé d'un moyeu rigide (1), obturé en son intérieur par une plaque (2). Sur cet ensemble est monté un manchon cylindrique dilatable (3) fixé périphériquement à ses extrémités (5) et (5') de façon étanche et résistance sur le moyeu. The present invention aims to remedy these drawbacks. It relates to a device for closing pipes consisting of a rigid hub (1), closed inside by a plate (2). On this assembly is mounted an expandable cylindrical sleeve (3) fixed peripherally at its ends (5) and (5 ') in a sealed manner and resistance on the hub.

Un dispositif (4) permet par injection d'un fluide, air ou eau par exemple, de gonfler l'espace compris entre le moyeu et le manchon. La plaque d'obturation (2) du moyeu peut être équipée avantageusement d'un système d'ancrage ou d'accrochage (7). Elle peut aussi être pourvue, accessoirement, d'un dispositif (8) permettant le raccordement d'une tuyauterie traversant de façon étanche l'obturateur; ce dispositif destiné à épuiser d'un côté de l'obturation, ou à mettre en pression l'espace compris entre deux obturateurs.A device (4) makes it possible by injecting a fluid, air or water for example, to inflate the space between the hub and the sleeve. The hub cover plate (2) can advantageously be fitted with an anchoring or attachment system (7). It can also be provided, incidentally, with a device (8) allowing the connection of a pipe passing tightly through the shutter; this device intended to exhaust one side of the shutter, or to pressurize the space between two shutters.

Le manchon (1) est une membrane cylindrique en matériau souple et élastique du type élastomère, ou plastomère par exemple. Cette membrane (3) comprendra une zone centrale de très grande souplesse permettant un allongement tant longitudinal que transversal important, et deux zones situées de part et d'autre de la première. Celles-ci seront renforcées par des fibres ou des cables (6) en matière synthétique, métallique ou autre - disposés de telle manière qu'ils permettent la dilatation diamétrale tout en reprenant les efforts longitudinaux dûs à la pression de gonflage interne. The sleeve (1) is a cylindrical membrane of flexible and elastic material of the elastomer type, or plastomer for example. This membrane (3) will include a central zone of great flexibility allowing a significant longitudinal and transverse elongation, and two zones located on either side of the first. These will be reinforced by fibers or cables (6) made of synthetic, metallic or other material - arranged in such a way that they allow diametrical expansion while taking up the longitudinal forces due to the internal inflation pressure.

La fixation des extrémités du manchon (5) et 5') sur le moyeu sera rendue étanche par collage, vulcanisation ou intercalage d'un joint, ou par tout autre procédé. Un blocage mécanique du type cerclage (9) ou manchonnage par exemple interdira toute dilatation à ce niveau et reprendra les éventuels efforts de traction suivant le mode d'étanchéité choisi.  The attachment of the ends of the sleeve (5) and 5 ′) to the hub will be made leaktight by gluing, vulcanization or intercalation of a seal, or by any other method. A mechanical blocking of the strapping (9) or sleeving type for example will prevent any expansion at this level and will take up any tensile forces according to the sealing mode chosen.
