Abstract
A sealing gasket (9, FIG. 1 ) has a spiral wound element 10 secured to a surrounding locating plate 11 which is thinner than usual locating rings and may include bolt apertures 23.sub.1 etc. The plate 11 has a central aperture 22 which is surrounded by simple embossment 26 inclined to the longitudinal axis at an angle corresponding to the inclination of the ridge 21 presented by the outer turn of the spiral wound element. The aperture 22 receives the sealing face 18 of the element thereby and overlies the ridge 21 to which it is spot welded at a plurality of points. The plate has some resilience permitting the spiral wound element to compress properly under load, but being simple to fabricate and assemble.
Claims21
A sealing gasket arrangement comprising
- (1) a spiral wound element, wound about a longitudinal axis, and including, between sealing faces that are separated along its longitudinal axis and extend orthogonally thereto, a resilient section comprising a ridge extending outwardly from said longitudinal axis and formed by metallic surfaces inclined to said axial direction, and
- (2) a locating plate having a through-aperture, corresponding in outline to the spiral wound element and dimensioned greater than the sealing faces but smaller than the element as a whole, and an embossment surrounding said aperture and inclined with respect to a plane of the plate to one side only thereof at an angle corresponding to the inclination of a said metallic surfaces said ridge, said embossment being secured to one surface of said ridge at a plurality of locations about the periphery of the through-aperture.
A sealing gasket arrangement comprising
- (1) a spiral wound element, wound about a longitudinal axis, and including, between sealing faces that are separated along its longitudinal axis and extend orthogonally thereto, a resilient section comprising a ridge extending outwardly from said longitudinal axis and formed by metallic surfaces inclined to said axial direction, and
- (2) a locating plate having a through-aperture, corresponding in outline to the spiral wound element and dimensioned greater than the sealing faces but smaller than the element as a whole, and an embossment surrounding said aperture and inclined with respect to a plane of the plate to one side thereof at an angle corresponding to the inclination of a said metallic surfaces of said ridge, said embossment being secured to said ridge at a plurality of locations about the periphery of the through-aperture, and wherein said embossment extends from the through-aperture for a distance greater than the inclined surface of said ridge whereby the plane of the plate surrounding said embossment is not centrally disposed axially between said sealing faces of the spiral wound element.
A method of manufacturing a sealing gasket arrangement comprising
- (1) forming a spiral wound element, wound about a longitudinal axis, and including, between sealing faces that are separated along its longitudinal axis and extend orthogonally thereto, a resilient section comprising a ridge extending outwardly from said longitudinal axis and formed by metallic surfaces inched to said axial direction, and
- (2) forming a locating plate having a through-aperture, corresponding in outline to the spiral wound element and dimensioned greater than the sealing faces but smaller than the element as a whole,
- (3) providing at the periphery of the through-aperture an embossment surrounding said aperture and inclined with respect to the plane of the plate to one side only thereof at an angle corresponding to the inclination of a said metallic surfaces of the ridge of the element, and
- (4) securing said embossment to one surface of said ridge at a plurality of locations about the periphery of the through-aperture.

- (4) resistance welding said embossment to said ridge at a plurality of locations about the periphery of the through-aperture;
- and wherein said through-aperture in the locating plate and said inched embossment are formed by punching the material of said aperture from the plate and simultaneously therewith deforming the periphery of the aperture to form the embossment.
