Background

The pipes of the water supply and drainage pipelines are very rich, and the large-caliber pipelines for long-distance and large-flow transportation of urban water supply are mainly prestressed concrete pipes. Because the interfaces and the connection modes between pipelines of different materials are different, the interface connection is not tight, and the water leakage phenomenon occurs. The general interface mode of the prestressed concrete pipe and the steel pipe is that the faucet of the prestressed concrete pipe is made into a steel faucet, and sealing treatment is carried out by adopting rubber rings and the like. The method not only makes the manufacturing process of the pipeline complex, and leads to the improvement of manufacturing cost, but also has poor sealing property at the joint of the pipeline, and the water leakage phenomenon is generated when the gap of the pipeline is larger.

the utility model provides a steel pipeline socket joint formula interface, includes first bellmouth, first socket, and first bellmouth, first socket are located first pipeline both ends respectively, and wherein, first bellmouth passes through rubber circle sealing connection with the second socket of second pipeline, and first socket passes through rubber circle sealing connection with the second bellmouth of second pipeline.

The first bell mouth comprises a first annular plate, a bell mouth pipe is fixed at the end of the first annular plate, and the inner diameter of the bell mouth pipe is matched with the outer diameter of the second socket.

The first socket comprises a second annular plate, a socket pipe is fixed at the end of the second annular plate, and the outer diameter of the socket pipe is matched with the inner diameter of the second bell mouth.

The socket pipe is welded with annular ribs.

The first annular plate and the first pipeline and the second annular plate and the first pipeline are reinforced by a plurality of second rib plates.

The ends of the socket pipe and the spigot pipe are respectively provided with a chamfer angle.

The second annular plate and the spigot pipe are reinforced by the first rib plate.

The outer wall of the second socket is provided with a bulge.

The steel pipeline socket joint has the following technical effects: the two ends of the steel pipe are respectively provided with a first bell mouth and a first spigot, the first spigot of the steel pipe is in sealing connection with the second spigot of the prestressed concrete pipe, and the installation between the steel pipe and the prestressed concrete pipe is completed. The device overcomes the defect that the joint gap is too large due to different wall thicknesses of pipelines between different materials, so that the sealing is not thorough, has good durability, impermeability and joint water closure, has simple structure and good sealing performance, and greatly reduces the water leakage risk of the pipelines.
