Title (EN) DEVICE FOR FASTENING A MANOEUVRABLE PLUG FOR PLUGGING OF PIPES
(FR) DISPOSITIF POUR FIXER UN BOUCHON MANOEUVRABLE DESTINE A BOUCHER UN TUYAU
Abstract: front page image
(EN)Arrangement at a plug for sealing liquid- or gas-carrying pipes, comprising several slips (15) arranged peripherally on the plug, so as to allow them to be pushed up along a conical force ring (25) by means of a hydraulic cylinder (5), where the slips (15) are provided with a possibly divided sliding surface (19, 19') and at least one possibly divided sliding surface (20, 23) having an angle that differs from the angle of the sliding surface (19, 19'). The force ring (25) has sliding surfaces (27, 29, 29', 31) that correspond to the sliding surfaces (19, 19', 20, 23) of the slips. The first part of the sliding surfaces (20, 23, 27, 31) has a steep gradient and the second part of the sliding surfaces (21, 21', 29, 29') has a small gradient.
(FR)L'invention concerne un dispositif pour bouchon destiné à fermer un tuyau de transport de liquide ou de gaz, qui comprend plusieurs éléments glissants (15) disposés sur la périphérie du bouchon de façon qu'ils puissent être poussés vers le haut le long d'une bague de force conique (15) au moyen d'un vérin hydraulique (5). Les éléments glissants (15) sont pourvus d'une surface de glissement (19, 19') éventuellement divisée et d'au moins une autre surface de glissement (20, 23) éventuellement divisée, dont l'angle diffère de celui de la première surface de glissement (19, 19'). La bague de force (25) présente des surfaces de glissement (27, 29, 29', 31) qui correspondent aux surfaces de glissement (19, 19', 20, 23) des éléments glissants. La première partie des surfaces de glissement (20, 23, 27, 31) présente un fort gradient, et la seconde partie des surfaces de glissement (21, 21', 29, 29') présente un faible gradient.
