    • A composite pressure vessel (1) including a fluid port (22) extending through the composite sidewall structure (2) formed by providing a radial hole (26) through the sidewall structure (2) for receipt of an externally removable porting plug (24). The porting plug (24) is retained within the radial hole (26) by threaded engagement in an internally threaded grommet (28) which may either be incorporated into the composite windings (4, 6) of the sidewall structure (2) or held in place against the exterior surface of the sidewall structure (2) by local composite windings (30). At the inner end of the porting plug (24) is a seal groove (38) containing a ring seal (40) which is sized to form a fluid-tight seal around a porting hole (48) in a liner member (8) in the interior of the sidewall structure (2) to prevent fluid leakage between the porting plug (24) and liner member (8). The inner diameter of the seal groove (38) is formed by a reduced diameter end portion (36) at the inner end of the porting plug (24), whereas the outer diameter of the seal groove (38) is formed by a back-up ring (42) surrounding such reduced diameter end portion (36) in radial spaced relation therefrom. The back-up ring (42) is preloaded against the liner member (8) during threading of the porting plug (24) into the grommet (28) to ensure a tight fit between the back-up ring (42) and liner member (8).
    • 复合材料压力容器(1)包括一个流体出口(22)通过复合侧壁结构(2)延伸通过所述侧壁结构(2)用于接收从外部可移除移植插头提供的径向孔(26)(24)而形成 , 移植插头(24)被保持在径向孔(26)通过螺纹接合其可以是结合到所述复合绕组的内部护环螺纹(28)(4,6)的侧壁结构(2)或保持在内 放置靠在侧壁结构(2)由本地复合绕组(30)的外表面。 在移植塞的内端部(24)是含有一个环形密封件(40)的所有其尺寸,以形成围绕在衬套部件上的移植孔(48)以流体密封的密封件(8)的密封槽(38) 侧壁结构(2)的内部,以防止移植插头(24)和衬垫构件(8)之间的流体泄漏。 密封槽的内径(38)是通过在移植插头(24)的内端的直径减小的端部(36)形成,而所述密封槽的外径(38)由背FORMED 挡圈(42),从那里周围在径向间隔开的关系检查缩径端部(36)。 该支撑环(42)的移植插头(24)插入到护环(28)的纸期间靠在衬垫构件(8)预加载,以确保支撑环(42)和衬垫部件之间的紧密配合( 8)。
