Title
(EN) ARTICULATE CONNECTION PIECE FOR TUBES
(FR) PIECE DE RACCORDEMENT ARTICULE POUR TUBES
Abstract
(EN)
The invention relates to a connection piece (1) for the articulate connection of a first and a second tube (3, 5), in particular a first and a second tube (3,5) of a hot air supply system fed from the power unit of an aircraft, with the possibility of compensating for tolerances, wherein an interval (40) between a tube end (2) of the first tube (3) and a tube end (4) of the second tube (5) is enclosed by a sealing mechanism (6). According to the invention both tube ends (2, 4) each have a support ring (14, 15), wherein the support rings (14, 15) are connected to each other by at least two connection means arranged outside the sealing mechanism (6). At least two metal bellows (7, 8) are preferably used as the sealing mechanism (6), which enable almost maintenance-free operation. Steel ropes (22, 23) are preferably used as connection means. In particular, tubes (3, 5) with a diameter of up to 160 mm, which are intended, depending on the material used, to conduct media with temperatures of up to 8500C and pressures of up to 20 bars, can be connected in an articulate manner to each other by means of the connection piece (1) of the invention.
(FR)
L'invention concerne une pièce de raccordement (1) destinée au raccordement articulé d'un premier et d'un second tubes (3, 5), en particulier un premier et un second tubes (3, 5) d'un système d'alimentation en air chaud animé par le bloc de puissance d'un aéronef, avec possibilité de compenser des tolérances, un intervalle (40) situé entre une extrémité (2) du premier tube (3) et une extrémité (4) du second tube (5) étant enfermé par un mécanisme d'étanchéité (6). Selon l'invention, les deux extrémités de tube (2, 4) présentent chacune une bague de support (14, 15), les bagues de support (14, 15) étant raccordées l'une à l'autre par au moins deux raccords disposés à l'extrémité du mécanisme d'étanchéité (6). Au moins deux soufflets métalliques (7, 8) sont, de préférence, utilisés pour servir de mécanisme d'étanchéité (6), ce qui permet une exploitation quasiment exempte d'entretien. Des cordes métalliques (22, 23) sont, de préférence, utilisées pour servir de moyens de raccordement. En particulier, des tubes (3, 5) d'un diamètre pouvant atteindre 160 mm, destinés, selon le matériau utilisé, à acheminer des supports dont les températures et les pressions peuvent atteindre 850 °C et 20 bars, respectivement, peuvent être raccordés l'un à l'autre de manière articulée, au moyen de la pièce de raccordement (1) de l'invention.
