ABSTRACT:
A sealing mechanism capable of use in a valve subject to extended temperatures and pressures. The sealing mechanism comprises a seal ring positioned within a groove circumferential with respect to the passageway of the valve. A convex seating portion of the seal ring extends through an annular opening in the groove, for sealing engagement with a closure member. Shoulder portions, which extend from the sides of the seating portion, abut the sidewalls of the groove. The seal ring is compressed in width within the groove, so that a resilient side-sealing force is imparted to the contact of the shoulder portions with the sidewalls of the groove. Substantially leak proof sealing is achieved, which is maintained even in the event of high temperature conditions or fire.
