The invention discloses a pipeline connecting structure which comprises a first connecting piece, a second connecting piece, a first sealing lantern ring, graphite packing and a second sealing lantern ring, the second connecting piece is provided with an extending sleeve, the sleeve is provided with a main body part and a limiting part, and the limiting part is arranged on the periphery of the main body part; the graphite packing is arranged between the first connecting piece and the sleeve, the first connecting piece is sleeved with the first sealing lantern ring, the first end of the first sealing lantern ring extends to the position between the first connecting piece and the sleeve and abuts against the graphite packing, and the second end of the first sealing lantern ring abuts against the graphite packing. The second sealing lantern ring is arranged on the periphery of the main body part in a sleeving mode and abuts against the limiting part, and the first sealing lantern ring is fixedly connected with the second sealing lantern ring. Axial and radial sealing between the first connecting piece and the second connecting piece is achieved through axial and radial extrusion of the first sealing lantern ring and the second sealing lantern ring on the graphite packing, and good sealing performance is achieved under the working conditions of high temperature and high pressure.

    本发明公开了一种管路连接结构,包括第一连接件,第二连接件,第一密封套环,石墨盘根及第二密封套环,所述第二连接件设有延伸的套筒,所述套筒具有主体部和限位部,限位部设置于主体部外周,所述石墨盘根设置在所述第一连接件与套筒之间,所述第一密封套环套设于所述第一连接件外,所述第一密封套环的第一端部延伸至所述第一连接件与套筒之间,并抵压所述石墨盘根,所述第二密封套环套设在主体部外周并抵压所述限位部,所述第一密封套环与第二密封套环固定连接。通过第一密封套环和第二密封套环对石墨盘根的轴向和径向挤压,实现第一连接件与第二连接件之间的轴向及径向密封,在高温高压工况下具有良好的密封性能。
