초록 ▼

A seal for long-time exposures in oil and gas well tools. The seal is adapted for use in a sealed joint between two relatively movable members. In particular, the seal is designed for relatively slidable members. The seal has a body portion with a pair of annular arms extending from opposite sides thereof. A lip on each of the arms is adapted for engaging one of the relatively movable members. An elastomeric sealing element may be disposed in a groove in the body portion for dynamic sealing between the first and second members. Pusher rings may be disposed on opposite sides of the seal so that the seal may be clamped against one of the relatively movable members without the lips or arms longitudinally engaging either of the relatively movable members or a lock ring used to clamp the seal in place.

A sealed joint comprising: a first member having a sealing surface defining first and second diameters; a second member having a sealing surface defining first and second diameters, said first and second members being relatively movable between first and second positions; an annular shoulder extending between said first and second diameters of said sealing surface of said second member; a seal disposed between said first and second members and comprising: a metal body portion defining a groove therein; first and second annular metal arms extending from a side of said body portion and defining an annular groove therebetween; third and fourth annular metal arms extending from an opposite side of said body portion from said first and second annular arms and defining an annular groove therebetween; first, second, third and fourth metal lips on said first, second, third and fourth arms, respectively, wherein: said first and third lips are spaced from said first diameter of said sealing surface of said first member when said first and second members are in said first position; said first and third lips are adapted for metal-to-metal sealing engagement with said second diameter of said sealing surface of said fist member when said first and second members are in said second position; and said second and fourth lips are adapted for metal-to-metal sealing engagement with said second diameter of said sealing surface of said second member; and an elastomeric sealing element disposed in said groove in said body portion and adapted for sealing engagement between said first and second diameter of said sealing surface of said first member when said first and second members are in said first position and for tighter sealing engagement with said second diameter of said sealing surface of said first member when said first and second members are in said second position; clamping means for clamping said seal in a position adjacent to said shoulder; a first pusher ring disposed between said seal and said shoulder; and a second pusher ring disposed between said seal and said clamping means.
