Title
(EN) JOINT ASSEMBLY EMPLOYING MULTI-RING GASKET
(FR) RACCORD COMPRENANT UN JOINT D'ETANCHEITE STATIQUE A PLUSIEURS ANNEAUX
Abstract
(EN)
A multi-ring gasket (140) is for sealing the joint between two flanged general nonmetallic pipes. In one embodiment, the gasket has an inner ring (72) an outer ring (132) and a plurality of spokes (77) connecting the inner ring (72) to the outer ring (132). The various gasket embodiments have additional features, including having a substantially inset outermost ring (132) so that the gasket (140) may be used with a flange having a mating surface interior of the bolts employed to draw the flanges together; having spokes (96) that do not encircle the bolts but that provide for aligning the gasket with respect to the bolts and the flanges; having an outer periphery (102) that is at least partially rectilinear; having one or more peripheral notches (112) for receiving a thickness gauge; and having a tab (144) for manipulating the gasket (140) in the installation thereof.
(FR)
Joint d'étanchéité statique (40) à plusieurs anneaux, destiné à sceller un raccord entre deux tuyaux à bride, généralement non métalliques. Dans un mode de réalisation, le joint d'étanchéité comporte un anneau (72) intérieur, un anneau (132) extérieur ainsi qu'une pluralité de rayons (77) reliant l'anneau (72) intérieur à l'anneau (132) extérieur. Les divers modes de réalisation de ce joint d'étanchéité comportent des caractéristiques supplémentaires, à savoir notamment un anneau (132) situé le plus à l'extérieur, sensiblement en retrait par rapport à la bride, de manière à pouvoir utiliser ce joint (140) avec une bride possédant une surface de raccordement située en deçà des boulons utilisés pour rapprocher les brides; ou encore des rayons (96) n'encerclant pas les boulons mais permettant d'aligner le joint d'étanchéité par rapport aux boulons et aux brides; ou encore une périphérie (102) extérieure dont le contour est au moins partiellement rectiligne; ou encore une ou plusieurs encoches (112) périphériques destinée(s) à recevoir une jauge d'épaisseur; ou enfin une languette (144) destinée à la manipulation du joint d'étanchéité (140) aux fins de l'installation de celui-ci.
