Description

TECHNICAL FIELD

[0001] The utility model relates to pipeline technical field especially relates to a steel pipeline socket. BACKGROUND

[0002] In pipeline construction, it is often necessary to connect concrete pipes with steel pipes, one end of which is provided with a socket and the other end is provided with a socket. The end of the concrete pipe can be inserted into the socket, and the socket is used to insert the concrete pipe. Patent No. 202223490393.8 discloses a steel pipe socket interface, which comprises a first socket and a first socket. The first socket and the first socket are respectively located at the two ends of the first pipe. Among them, the first socket and the second socket of the second pipe are connected by a rubber ring, and the first socket and the second socket of the second pipe are connected by a rubber ring. The steel pipe socket interface can realize the sealing connection of pipes of different materials and reduce the risk of water leakage. However, the inner side of the socket adopts multiple first rib plates for reinforcement, although the cost is low, but the right angle corner formed between the second annular plate and the socket pipe increases the resistance of the water flow, and the particulate impurities are also easy to accumulate here. SUMMARY

[0003] The technical problem to be solved by the utility model is to provide a steel pipe socket in view of the above technical deficiencies.

[0004] To solve the above technical problems, the utility model adopts the following technical scheme: a steel pipe socket, comprising a pipe body, one end of the pipe body is provided with a ring plate, the side of the ring plate away from the pipe body is provided with a socket pipe, a support is arranged between the ring plate and the pipe body, a bevel ring is arranged between the inner side of the socket pipe and the ring plate, the outer side of the bevel ring contacts the inner side of the socket pipe, one side of the bevel ring contacts the end of the pipe body, the inner side of the bevel ring is a tapered surface, and the diameter of the tapered surface gradually decreases from the direction away from the pipe body to the direction close to the pipe body.

[0005] Further optimize the technical scheme, the outer edge of the end of the socket pipe away from the ring plate is provided with a chamfer.

[0006] Further optimize the technical scheme, the outer side of the socket pipe is further provided with a steel ring.

[0007] Compared with the prior art, the utility model has the following advantages: a bevel ring is arranged between the inner side of the socket pipe and the ring plate, the inner side of the bevel ring is a tapered surface, and the diameter gradually decreases from the direction away from the pipe body to the direction close to the pipe body, so that the resistance of the water flow is small, and the particulate impurities are not easy to accumulate here. BRIEF DESCRIPTION OF DRAWINGS

[0008] Fig. 1 It is a structural schematic diagram of a steel pipe socket.

[0009] Fig. 2 Structure diagram of the bevel ring.

[0010] In the figure: 1, pipe body; 2, ring plate; 3, reinforcing ring; 4, spigot pipe; 5, bevel ring; 51, taper surface; 6, support. DETAILED DESCRIPTION

[0011] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model is further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0012] DETAILED DESCRIPTION: in combination with Figs. 1-2 As shown in the figure, a steel pipe spigot comprises a pipe body 1 made of steel, one end of the pipe body 1 is provided with a ring plate 2 made of steel, the ring plate 2 is perpendicular to the pipe body 1, the side of the ring plate 2 away from the pipe body 1 is provided with a spigot pipe 4 made of steel, preferably the spigot pipe 4, the ring plate 2 and the pipe body 1 are coaxial. A support 6 is arranged between the ring plate 2 and the pipe body 1, a bevel ring 5 is arranged between the inner side of the spigot pipe 4 and the ring plate 2, the cross section of the bevel ring 5 is a right triangle, the outer side (i.e. one right angle side) of the bevel ring 5 is in contact with the inner side of the spigot pipe 4, one side (i.e. the other right angle side) of the bevel ring 5 is in contact with the end of the pipe body 1 and the ring plate 2, the inner side (i.e. the hypotenuse) of the bevel ring 5 is a taper surface 51, the taper surface 51 gradually decreases in diameter in the direction from away to close to the pipe body 1, and the diameter of the end with smaller diameter is equal to the inner diameter of the pipe body 1. Due to the existence of the taper surface 51, not only the resistance to water flow is small, but also the particulate impurities are not easy to accumulate here. The spigot of the present application is located at one end of the pipe body 1, and the other end of the pipe body 1 is generally provided with a socket.

[0013] Further, the outer edge of the end of the spigot pipe 4 away from the ring plate 2 is provided with a chamfer, and the chamfer is preferably 45°.

[0014] Further, the support 6 can be a plurality of rib plates.

[0015] Further, the outer part of the spigot pipe 4 is further provided with a reinforcing ring 3 for preventing the sealing ring from moving backward.

[0016] The above only describes the preferred embodiments of the utility model, and is not intended to limit the utility model, and any modification, equivalent replacement and improvement made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
