摘要： There is disclosed a safety valve for use in well bore operations, for example, in cooperation with a progressive cavity pump or rodpump. In one embodiment of the invention, a safety valve (1) disclosed which is designed for use with upper and lower conduits in the form of upper and lower pump rod strings (16, 18) located in wellbore production tubing (50). The safety valve comprises a housing (2) having a longitudinal bore (3) extending therethrough; a coupling member (14) for coupling the upper rod string to the lower rod string, the coupling member sealably mounted within the longitudinal bore; an annular flow passage (8) bypassing the coupling member; and valve means comprising a valve sleeve (23) located in the annular flow passage. In use, the valve sleeve is utilised to control flow of fluid through the flow passage bypassing the coupling member.

摘要： An annular sealing element (12) to seal between metal surfaces for use in flanges, joints, packers and the like, located in oil and gas exploration and production equipment. The sealing element has inner and outer metal deformable surfaces (20, 22) joined at ends (24, 26), defining an interior volume (30) which is entirely filled with a plastic deformable material (28). The surfaces are arranged such that on compression of the element (12) from the ends (24, 26), the element will deform in a controlled manner on a cantilever principle. The volume of filler (28) and the interior volume (30) remain substantially equal during compression so that delamination does not occur. Thus the sealing element provides a seal combining the flexibility of elastomer seals with the integrity of a metal to metal seal.
摘要翻译：用于密封在用于法兰，接头，封隔器等的金属表面之间的环形密封元件（12），其位于油气勘探和生产设备中。密封元件具有在端部（24,26）处接合的内部和外部金属可变形表面（20,22），限定内部容积（30），其完全填充有可塑性可变形材料（28）。表面布置成使得在从端部（24,26）压缩元件（12）时，元件将以受控的方式以悬臂原理变形。填料（28）和内部容积（30）的体积在压缩期间保持基本相等，因此不会发生分层。因此，密封元件提供将弹性体密封件的柔性与金属密封件的完整性相结合的密封件。
