可固化介质充填管外封隔器
摘要：
一种可固化介质充填管外封隔器。为了克服现有化学介质充填固化型管外封隔器结构复杂，在操作中零部件失效将导致作业失败，影响施工作业的正常进行的不足，本实用新型包括上接头(1)、中心管(2)、连接管(17)、胶筒总成(9)，上接头(1)、中心管(2)、连接管(17)由上至下依次固定连接，胶筒总成(9)安装在中心管(1)外圆的中下部，安装在中心管(2)外圆的胶筒总成(9)端部依次安装有控制阀总成(8)、活塞总成(14)，控制阀总成(8)、活塞总成(14)上下对称、相向安装。其有益效果是结构合理，受力均匀，施工工艺简单，无需单独下管柱胀封，易于操作。
摘要（英）：

The utility model relates to an external packer for a solidifiable medium filling tube, aiming at overcoming the defects that the current chemical mediator filling solidifying tube external packer is complex in structure, the operation fails as parts are invalid in operation, and the normal operation is influenced. The external packer comprises an upper joint (1), a central tube (2), a connecting tube (17) and a rubber barrel assembly (9), wherein the upper joint (1), the central tube (2) and the connecting tube (17) are sequentially and fixedly connected from top to bottom; the rubber barrel assembly (9) is arranged at the lower middle part of the excircle of the central tube (2); and a control valve assembly (8) and a piston assembly (14) are sequentially arranged at the end part of the rubber barrel assembly (9) at the excircle of the central tube (2), and are arranged oppositely in an up and down symmetrical way. The external packer for the solidifiable medium filling tube has the benefits of being reasonable in structure, uniform in stress, simple in construction technology, free of an independent tubular column for expanding sealing, and easy to operate.
