Pipeline joint capable of improving ring stiffness and tensile strength

Abstract

The invention relates to the technical field of pipeline joints, and discloses a pipeline joint capable of improving ring stiffness and tensile strength. The pipeline joint comprises a pipeline socketand a pipeline spigot, the wall of the pipeline socket is fixedly connected with a first annular boss, a first conical slope is arranged at the inner wall, far away from the pipeline socket, of the first annular boss, a plurality of annular reinforcing ribs are fixedly connected to the outer wall of the pipeline socket, a plurality of straight reinforcing ribs are fixedly connected to the outer wall of the pipeline socket, a plurality of second annular bosses are fixedly connected to the outer wall of the pipeline spigot, a second conical slope is formed in the outer wall, away from the pipeline spigot, of one of the second annular bosses, and the plurality of adjacent second annular bosses are combined to form a sealing ring groove. The pipeline joint capable of increasing the ring stiffness and the tensile strength has the advantages of being high in water tightness and capable of avoiding the problem that a pipeline has a leakage problem and pollutes the environment, improving theenvironment friendliness of the pipeline joint, avoiding the problem that the pipeline joint is blocked, guaranteeing the pipeline drainage efficiency and the like.

Description

technical field [0001] The invention relates to the technical field of pipe joints, in particular to a pipe joint with increased ring stiffness and tensile strength. Background technique [0002] Pipe joints are mainly used for quick connection between pipes. There are many ways to connect plastic or plastic composite sewage pipes. The rigid connection process is too complicated and difficult to construct. It is also faced with settlement, displacement, thermal expansion and contraction without compensation. Under the circumstances, it is easy to cause damage to the interface or the pipe body. The socket-type rubber ring seal belongs to the flexible interface, which is more convenient to install and widely used. [0003] The watertightness of the interface of the existing socket-type pipe joint is not ideal, mainly due to the large thermal expansion and contraction coefficient, and the axial compensation due to the temperature difference before backfilling is easy to cause t...
