    摘要： A main seal assembly for a valve comprising a resilient seal ring carried in an annular groove or recess in one working surface to seal against an opposing working surface. The inner sidewall portions of the recess are sloped in converging relationship from the bottom surface and then merge into generally parallel outer sidewall portions forming a relatively narrow opening. The seal ring is of generally triangular cross section with lateral protuberances that seal against the sloping inner sidewall portions of the recess and is mechanically retained by the narrow outer recess opening. A relatively thin outer protuberance extends freely between the outer sidewall portions of the recess to seal against the opposing working surface.
