ABSTRACT:
A fluid packing comprising a stacked assembly of V-ring seal elements, special backup/energizing rings interspersed between the seal elements, and a spring-energized lip seal ring that is retained in functional position by an adapter ring having a generally tee-shaped cross-sectional configuration. As the assembly is installed in a stem packing chamber of a valve or choke, or in the packing chamber of a wellhead lockdown screw, with the T-adapter ring at one end of the assembly and a backup ring for the V-ring seal elements at the other end, the lip seal ring and the V-ring seal elements are radially compressed to establish an initial seal between the stem or screw and the chamber wall. When the assembly is subjected to internal valve, choke or wellhead pressure, the V-ring seal elements and the lip seal ring are additionally compressed and deformed to fill annular spaces that may still exist between the seal elements, their backup/energizing rings and the lip seal ring, thereby establishing an essentially void-free dynamic packing between the stem or screw and the chamber wall that is capable of withstanding a large amount of stem or screw movement.
