一种管道应急维修用密封装置及方法
摘要：
本发明公开了一种管道应急维修用密封装置及方法，所述装置包括：左上半法兰、左下半法兰、右上半法兰、右下半法兰、密封件、若干螺栓；左上半法兰与左下半法兰通过螺栓连接形成左法兰；右上半法兰与右下半法兰通过螺栓连接形成右法兰；左法兰和右法兰分别与管道安装抱紧左上半法兰与左下半法兰、右上半法兰与右下半法兰通过螺栓连接对密封件形成竖直方向的压缩负荷对密封件进行紧固；左上半法兰与右上半法兰、左下半法兰与右下半法兰通过螺栓连接对密封件形成水平方向的压缩负荷对密封件进行紧固；本装置解决狭小空间、高温高压苛刻环境下管道预防及应急维修技术难题，为管道类部件维修，提供必备的设备和方法。
摘要（英）：

The invention discloses a sealing device and method for emergency maintenance of a pipeline. The sealing device comprises an upper left half flange, a lower left half flange, an upper right half flange, a lower right half flange, a sealing piece and a plurality of bolts, wherein the upper left half flange and the lower left half flange are connected through the corresponding bolt to form a left flange, and the upper right half flange and the lower right half flange are connected through the corresponding bolt to form a right flange; the left flange and the right flange are mounted on the pipeline in a clamping mode; the upper left half flange and the lower left half flange are connected through the corresponding bolt and the upper right half flange and lower right half flange are connectedthrough the corresponding bolt to form a vertical compression load applied to the sealing piece so as to fasten the sealing piece; and the upper left half flange and the upper right half flange are connected through the corresponding bolt and the lower left half flange and the lower right half flange are connected through the corresponding bolt to form a horizontal compression load applied to thesealing piece so as to fasten the sealing piece. By adoption of the sealing device and method for emergency maintenance of the pipeline, pipeline prevention and emergency maintenance in narrow spacesunder high-temperature and high-pressure severe environments are achieved, and the necessary device and method are provided for pipeline maintenance.
