The rubber seal ring for flexible interface is a ring structure, and the contour line of its section shape is closed from the upper dovetail shaped curve part and the inner and outer side and bottom line segments. The upper dovetail shaped curve part of the new model increases the compression sealing stress while facilitating the installation, and improves the sealing performance of the rubber ring,With the increase of water pressure in the pipeline system acting on the curved surface where curve L1 is located and the curved surface where the second curve L2 is located, the curved surface and the sealing ring are more closely attached, and the sealing performance of the sealing ring is better. At the same time, the 50 and 90 degree hardness composition of the rubber ring in the past is changed to a single 60-80 degree rubber material, which improves the production efficiency and quality of the rubber ring,The new structure of rubber ring improves the safety and stability of pipeline interface sealing As the "lifeline" of cities, underground pipelines are becoming more and more important in the development of modern cities. All kinds of underground pipelines play a role in the "metabolism" of cities. As the importance of underground pipeline system is gradually recognized, various forms of improvement, from the selection of pipeline materials to pipeline joints, have been improved. Most of the damage to underground pipelines is mainly caused by earthquake,Therefore, in addition to meeting the functional requirements, better seismic performance has become the main criteria for the selection of pipes and pipeline joints. Flexible pipeline interfaces have many characteristics, especially their excellent seismic performance. Therefore, flexible interfaces have been widely used in pipeline laying Sealing the flexible interface of the double rubber ring pipeline can not only avoid the leakage caused by the undercut, adhesion and shear damage of the traditional pipe sealing rubber ring, but also solve the leakage problem caused by the uneven compression ratio of the sealing rubber ring. It also has the automatic sealing function of automatically increasing the compression ratio of the rubber ring to withstand the greater pressure of the pipeline and compensate for the decrease of the rebound force caused by the aging of the rubber ring,Therefore, this interface not only solves the problem that traditional pipe rubber ring sealing interface is prone to leakage, but also its sealing capacity can withstand the limit pressure of pipeline allowable stress, so that the pressure bearing capacity and effective sealing time of the interface are synchronized with the pressure bearing limit and service life of the pipeline. This interface is particularly suitable for traditional steel pipe forming by expanding forming process The material used for double sealed self-locking socket and spigot composite solid wall pipe shall be mainly polyethylene (PE), and additives to improve the processing performance or other properties of the pipe shall be added.The pipe is wound to increase the strength and toughness of the pipe, which is processed by the lathe later, thus forming a new type of pipe with high precision, high adhesion, high strength and convenient construction. The pipes are generally black, and other colors can be agreed by both parties.The inner and outer surfaces of the pipes shall be clean, and the black pipes shall be produced by composite winding, with clear and regular lines, and free of bubbles, obvious scratches, depressions, impurities, and uneven colors.The pipe end shall be cut flat and perpendicular to the pipe axis.
