1. Ocean flexible composite line tip withhold and connect, including joint overcoat, joint core, discharge valve and loose cover flange, its characterized in that:

the joint outer sleeve is in double connection with the joint core through threads and welding, and the exhaust valve is in threaded connection with the joint outer sleeve;

the joint outer sleeve is provided with threads connected with the joint core, a spigot for mounting and positioning and a boss for mounting the exhaust valve;

a loose flange is arranged on the joint core;

and the outer surface of the joint core is provided with ring teeth.

Technical Field

The invention relates to a crimping connector, in particular to a crimping connector for an end part of a marine flexible composite pipeline.

Background

When the flexible composite pipeline is laid under water, the length of the pipeline cannot be determined temporarily or more extra cost needs to be added when the pipeline is measured in advance, and the pipeline needs to be cut and connected after the length is determined when the pipeline is laid on site. The end part joint of the traditional marine flexible composite pipeline is directly provided with a hole on a joint outer sleeve and is connected with an exhaust system through welding after the on-site buckling is finished; the two joints are connected by adopting direct welding or welding a connecting flange; performing welding operations at a job site increases the amount of work on the site and increases costs.

It is in this context that this patent application proposes marine flexible composite pipeline end swage joints.

Disclosure of Invention

The invention mainly aims to overcome the defects in the prior art and provide the buckling and pressing joint for the end part of the marine flexible composite pipeline.

The invention is realized by the following technical scheme:

the marine flexible composite pipeline end buckling joint comprises a joint outer sleeve, a joint core, an exhaust valve and a loose flange;

the joint outer sleeve is in double connection with the joint core through threads and welding, and the exhaust valve is in threaded connection with the joint outer sleeve;

the joint outer sleeve is provided with threads connected with the joint core, a spigot for mounting and positioning and a boss for mounting the exhaust valve;

a loose flange is arranged on the joint core;

and the outer surface of the joint core is provided with ring teeth.

Due to the adoption of the technical scheme, the invention has the following advantages: the loose flange and the joint core are integrated by the manufacturing process, so that the welding connection between the loose flange and the joint core is reduced, the safety coefficient is improved, and the cost is reduced.

The invention is further illustrated with reference to the following figures and examples.

Detailed Description

The present invention is described in detail below with reference to the accompanying fig. 1-3.

As shown in figure 1, the exhaust valve comprises a loose flange 1, a joint core 2 with external surface provided with ring teeth, an exhaust valve 3 and a joint jacket 4 with internal surface provided with ring teeth, wherein the joint core 2 is connected with the joint jacket 4 at one end through threads, and then the joint core 2 and the joint jacket 4 are welded together. The loose flange and the joint core 2 are integrated by the manufacturing process, so that the welded connection of the loose flange and the joint core 2 is avoided, the safety coefficient is improved, and the cost is reduced;

as shown in fig. 2 and 3, during installation, one end of the pipeline 6 is placed in a cavity formed by the joint core 2 and the joint outer jacket 4, wherein the outer cladding 9 of the pipeline 6 is partially cut off and the connecting gasket 5 is installed. The joint core 2 and the joint outer sleeve 4 are respectively buckled and pressed by a buckling and pressing machine, so that teeth on the outer surface of the joint core 2 are pressed into the inner liner layer 7 of the pipe body, teeth on the inner surface of the joint outer sleeve 4 are pressed into the outer coating layer 9 of the pipe body, and the pipeline 6 is fixed, sealed and connected by one joint. The crimped joint jacket 4 is electrically connected to the metal layer 7 inside the pipeline 6 through the connection pad 5, thereby achieving electrical communication between the two joints.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiment according to the technical spirit of the present invention still fall within the scope of the technical solution of the present invention.
