| description | The utility model relates to a pipeline movable joint, which comprises an inner connection pipe, a female lock and an outer connection pipe, wherein, the contact surface of the outer connection pipe and the inner connection pipe is provided with a circumferential flute, and a sealing ring is arranged in the flute. The utility model can also comprises a pipe core arranged between the inner connection pipe and the outer connection pipe, a sealing ring is arranged between the pipe core and the inner connection pipe, and the sealing ring is in a sealing head shape. The inner connection pipe and the outer connection pipe can be both provided with a section of outer screw for connection. The utility model improves a traditional movable joint structure and is added with a pipe core, a sealing ring and inner and outer connection pipes which are provided with inner and outer screws, so the use flexibility of the movable joint is enhanced, and the pipeline repair is convenient. The utility model has the advantages of simple structure, simple manufacture, easy and rapid operation, etc., and the utility model can be widely suitable for being used in gas transmission pipelines and water supply pipelines with various standards. |
