Low leakage rate composite gasket

The present invention relates to a gasket (1) comprising a first discrete component and a second discrete component, wherein the first and second components (20) extend along the length of the gasket (1). The second component (20) is arranged relative to the first component (10) so as to separate the first component (10) at least from one of the two sealing surfaces (2, 4). The first component (10) is relatively hard in at least the thickness direction of the gasket (1) and preferably incompressible and the second component (20) is relatively soft in at least the thickness direction of the gasket (1) and compressible. When the gasket is compressed between two flanges (101, 102), there is a limited region of high compression, because the first component (10) increases the pressure by which the second component (20) is compressed between the surfaces of the flanges. This yields a high leak tightness of the sealing at a relatively low force.

The sealant strip comprises a pliable sealant material in which is embedded, along the length of the strip, one or more elastomeric cords (52, 52'). The invention provides an improved form of construction such that sealant in a non-hardened form, such as before setting or when of a non-setting form is not extruded from a joint overtime and thus the integrity of the joint is maintained.

Quand les portées (1, 2) à étancher s'approchent l'une de l'autre, le sac (9) est écrasé, le volume d'air supérieur (11) fuit à l'extérieur, les grains (10) transmettent une pression de contact importante entre les lèvres (5, 6) de l'enveloppe (4) et les portées (1 et 2). Ils ont pu subir des mouvements pendant l'écrasement de manière à uniformiser la pression en se répartissant dans le sac, même si des défauts de planéité importants existent entre les portées (1, 2).

HIGH COMPRESSIBILITY GASKET MATERIAL AND METHOD OF MAKING THE SAME

A highly compressible gasket material is formed by fusing two filled sheets of PTFE containing dispersed microballoons to a central unfilled sheet of PTFE which provides tensile strength to the material. The two unfilled sheets each constitute from 20% to 25% of the overall thickness of the gasket material. This method provides a unitary gasket assembly having an overall compressibility of 45% or more, but the thicker unfilled PTFE central area of the assembly provides excellent recovery characteristics and resistance to creep relaxation.

Seal between elements using corrugated rim - which is compressed to expand radially

Sealing between a pair of elements, such as between a polymer filter disc and a mounting housing, is effected by using a locking rim with a longitudinal corrugation. The rim is positioned in a peripheral recess of the disc and compressed to a flat state by applied pressure. The pressure causes radial inward and outward expansion of the rim to seal against the wall of the housing and the disc.
