摘要： A poppet valve arrangement is described such as can be used in a pipe terminal and/or flow coupler, said arrangement comprising: a poppet valve comprising a biasing device; and a housing comprising an inlet, an outlet and a flow channel configured to provide fluid communication between said inlet and said outlet when said poppet valve is open; wherein: said fluid communication provided by said flow channel is blocked by the poppet valve under action of said biasing device when the poppet valve is closed; and the poppet valve is supported with respect to the housing by a channel splitter that radially sections the flow channel into a sectioned substantially annular flow channel portion around the poppet valve.

摘要： Disclosed herein is a bellow for use in a ball valve, the bellow comprising: a metallic seat at an end of the bellow for providing a contact surface with a ball of a ball valve; and a metallic body integral with the seat; wherein the metallic body has a longitudinally elastic property such that, when the bellow is in use in a ball valve and the bellow is arranged within the housing of the ball valve so that it is always under longitudinal compression, substantially only the compression in the bellow causes the seat to apply a sealing force against the ball of the ball valve that maintains a mechanical seal between the seat and the ball valve. Advantageously, embodiments allow a new design of ball valve that maintains a high standard of performance in subsea environments over long time periods.

摘要翻译： 本文公开了一种用于球阀的波纹管，波纹管包括：在波纹管端部的金属座，用于提供与球阀的球的接触表面; 以及与所述座体一体的金属体; 其中金属体具有纵向弹性，使得当波纹管在球阀中使用时，波纹管布置在球阀的壳体内，使得其总是处于纵向压缩之下，基本上仅在波纹管中的压缩 使得座椅对球阀的球施加密封力，其在座椅和球阀之间保持机械密封。 有利地，实施例允许在长时间段内在海底环境中保持高标准性能的球阀的新设计。
