Valve coupling device forming metal-to-metal seal

摘要

A coupling element is disclosed that is capable of axial and lateral movement for use in connecting fluid lines such as control lines used in subsea drilling. The coupling element has a male sealing element with a first end, a second end, and a longitudinal axis extending between the first end and the second end. The male sealing element defines a generally frusto-conical sealing surface. A fluid passageway for the transmission of fluids is defined through the male sealing element along the longitudinal axis. The generally frusto-conical sealing surface forms a metal-to-metal seal when mated with a female sealing element. A female sealing element with a sealing surface that is complementary to the generally frustoconical sealing surface of the male coupling element is also disclosed. The female sealing element forms a pressure energized metal-to-metal seal with the male sealing element when the two are mated. A poppet valve element may be positioned within the fluid passageway of the female sealing element.
