Abstract
The utility model provides a 90-degree elbow PE end pipe fitting formed by steel-plastic conversion injection molding, which comprises a PE pipe fitting and a steel pipe; one end of the PE pipe fitting is formed into an integral 90-degree elbow pipe through injection molding; a rib plate is clamped between the 90-degree bent pipes; the joint surface of the PE pipe fitting and the steel pipe is a steel-plastic combined round surface connecting part, and the steel-plastic combined round surface connecting part is divided into a steel end and a plastic end; a stress ring is arranged outside the PE pipe fitting at the connecting part of the steel-plastic combined round surface; the steel end of the steel-plastic combined round surface is provided with a limiting spigot; and a sealing groove is formed in the end face of the limiting spigot. The utility model discloses a 90 jiaos of return bends department at the PE pipe fitting after injection moulding increases the gusset, is used for consolidating and strengthens the stability of PE pipe fitting, promotes the result of use.
Description
Technical Field
The utility model belongs to the technical field of natural gas pipe network and fluid transport pipe network. In particular to a PE end pipe fitting of a 90-degree elbow pipe formed by converting steel and plastic through injection molding.
Background
The steel-plastic conversion pipe fitting is used for a natural gas courtyard pipe network, is a conversion connecting device between a buried PE pipe and an outer wall steel pipe of an input building, and after the installation of a gas pipe network is completed, the courtyard backfill ground often can subside to a certain degree along with the lapse of time. The PE of the steel-plastic conversion pipe fitting moulds the interface with the steel pipe, receives the stress effect of ground subsidence, and easily produces pipe damage or even fracture, or causes the damage to ground steel pipe system through steel pipe transmission stress, makes the pipe network normally operate the interrupt.
Disclosure of Invention
To the weak point among the prior art, the utility model provides a conversion injection moulding 90 elbow formula PE end pipe fittings are moulded to steel. The utility model has the characteristics of conversion pipe fitting is moulded to protection steel.
In order to achieve the above purpose, the utility model discloses technical scheme as follows:
a90-degree elbow type PE end pipe fitting formed by steel-plastic conversion injection molding comprises a PE pipe fitting and a steel pipe; one end of the PE pipe fitting is formed into an integral 90-degree elbow pipe through injection molding; a rib plate is clamped between the 90-degree bent pipes; the joint surface of the PE pipe fitting and the steel pipe is a steel-plastic combined round surface connecting part, and the steel-plastic combined round surface connecting part is divided into a steel end and a plastic end; a stress ring is arranged outside the PE pipe fitting at the connecting part of the steel-plastic combined round surface; the steel end of the steel-plastic combined round surface is provided with a limiting spigot; and a sealing groove is formed in the end face of the limiting spigot.
Further, the 90-degree angle bent pipe is used for the plastic end of the steel-plastic conversion pipe fitting.
Furthermore, the rib plates are triangular and used for supporting the stability of the 90-degree bent pipe.
Furthermore, the wall thickness is increased through the steel-plastic combined round surface, so that the connection strength and the sealing performance are guaranteed, the influence of mechanical extrusion on the plastic end pipe body is reduced, the material structure stability of the pipe body is further guaranteed, and the service cycle is prolonged.
Has the advantages that: the utility model provides a conversion injection moulding 90 elbows PE end pipe fitting is moulded to steel is made into the shape of 90 elbows through the PE pipe fitting end with injection moulding to press from both sides the stability ability that is equipped with a gusset and supports the PE pipe fitting in 90 elbows department, strengthen the fastness of PE pipe fitting simultaneously, prevent that 90 elbows PE elbow pipe fitting from taking place to warp, increase life.

Detailed Description
The present invention is described below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
A90-degree elbow type PE end pipe fitting formed by steel-plastic conversion injection molding is shown in figures 1 to 4 and comprises a PE pipe fitting 1 and a steel pipe 2; one end of the PE pipe fitting 1 is formed into an integral 90-degree elbow 3 through injection molding; a rib plate 4 is clamped between the 90-degree bent pipes 3; the joint surface of the PE pipe fitting 1 and the steel pipe 2 is a steel-plastic joint round surface connecting part 5, and the steel-plastic joint round surface connecting part 5 is divided into a steel end and a plastic end; a stress ring 6 is arranged outside the PE pipe fitting at the steel-plastic combined round surface connecting part 5; the steel end of the steel-plastic combined round surface is provided with a limiting spigot; the end face of the limiting spigot is provided with a sealing groove.
Further, the 90-degree angle bent pipe 3 is used for the plastic end of the steel-plastic conversion pipe fitting.
Further, the rib plate 4 is triangular and used for supporting the stability of the 90-degree elbow 3.
Further, the wall thickness is increased to the combination disc is moulded to steel for guarantee joint strength and sealing performance, reduce and mould the influence that the end pipe body received mechanical extrusion, and then ensure the material stable in structure of body, increase life cycle.
