Description

T-shaped socket joint type plastic-coated steel pipe

Technical Field

The utility model relates to a steel pipe technical field especially relates to a T type socket joint formula plastic-coated steel pipe.

Background

The socket joint is mainly used for cast iron pipes, concrete pipes, ceramic pipes, plastic pipes and the like with socket joints. The socket pipe is divided into a rigid socket connection and a flexible socket connection. The rigid socket connection is characterized in that a spigot of the pipeline is inserted into a socket of the pipeline, and after alignment, caulking is performed by using caulking materials, and then sealing is performed by using sealing materials, so that the rigid socket connection is firmly closed. The flexible socket joint is characterized in that an elastic rubber ring is placed on the sealing end of the pipeline socket, and then the inserted end of the pipe is inserted by applying force to form a closed pipe capable of adapting to displacement and vibration within a certain range.

At present, in domestic markets, flexible connection can be used for connecting pipelines such as ductile iron pipes, concrete pipes, ceramic pipes, plastic pipes and the like, for steel pipes with huge market demands, connection is usually realized through other structures such as socket elbows, flanges or welding and the like, and the connection modes or the connection structures are complex, difficult to install or poor in sealing effect and cannot meet the use requirements. The field connection mode of the large-diameter water delivery steel pipes is mainly butt welding, the space of the bottoms of pipe ditches is narrow, the deviation of pipe orifices is large when the large-diameter pipelines slightly deform, the butt welding is difficult, the technical requirement on butt welding is high, labor and time are wasted (generally, one interface of DN2000 steel pipes needs 8 hours for butt welding), and the failure mode of domestic water delivery steel pipes is mainly weld joint cracking.

Although the flexible socket joint is provided with the notch for clamping the T-shaped rubber ring, in the actual use process, the insertion port is inserted into the socket and still pushes the T-shaped rubber ring, so that the sealing effect at the pipeline joint is poor.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a T type socket joint formula plastic-coated steel pipe, including setting up bellmouth and the interface at a steel pipe both ends, a steel pipe the interface inserts another steel pipe the bellmouth, be provided with the draw-in groove on the internal surface of bellmouth, install T type rubber circle in the draw-in groove, evenly be connected with a plurality of stoppers along circumference on the internal surface of bellmouth, the one end of stopper supports one side of T type rubber circle.

Furthermore, the inner diameter of the socket is larger than the outer diameter of the inserting port.

Furthermore, the surface of the steel pipe is provided with a plastic coating layer.

Furthermore, the limiting block is provided with at least 4 blocks.

Furthermore, a section of reducing port is arranged on the inserting port.

Further, the bellmouth is provided with a bulging section.

The utility model has the advantages that: because a plurality of limiting blocks are evenly connected to the inner surface of the bearing opening along the circumferential direction, the limiting blocks abut against one end of the T-shaped rubber ring to limit the movement of the T-shaped rubber ring, and when the inserting port of one steel pipe is inserted into the bearing opening of the other steel pipe, the T-shaped rubber ring cannot be pushed to move.
