Problems solved by technology

Since the current marine flexible pipeline is mainly made of high molecular polymer and metal through special processing, the joint plays a role in connecting the ends of the flexible hose, and the material is made of steel, so the connection between the joint and the pipeline is relatively complicated
The traditional small-diameter marine flexible hose achieves high-pressure sealing connection through extrusion deformation, which cannot meet the high-pressure sealing connection requirements of large-diameter marine hose

Embodiment Construction

[0009] 1. Treatment of the connection end of the seabed flexible hose: cut off the end of the interlocking skeleton layer 16 so as to put the joint core 22 into it. The polymer coatings 12, 14, the hose steel tape layer 13 are cut off from the hose ends.

[0010] 2. Installation at the end of the hose joint: install the sealing flange 11, the rubber seal 10, and the end of the joint 9 into the end of the hose in sequence, and then tighten the high-strength screws 8 on both sides to fix the position.

[0011] 3. Installation of the front end of the hose joint: install the sealing flange 7, the rubber seal 19, the metal pressure ring 20, the Y-shaped sealing ring 21, the joint core 22, and the joint front end 2 into the end of the hose in sequence, and insert the joint core The sub 22 is pressed into the hose polymer wrap 15 and then held in place by tightening high strength screws. At the same time, the joint flange 7 and the joint front end 2 are connected together by welding...

Abstract

A hose coupler for a seabed flexible hose comprises a coupler flange, a coupler front end, a coupler sleeve, polyurethane rubber, a high-strength screw, a rubber sealing member, a metal compression ring, a Y-shaped sealing ring, a coupler core, a sealing flange and a coupler tail end. Tensile layer flat steel is respectively and fixedly connected with the hose coupler and the sealing flange at the front end of the coupler through the high-strength screw, then the coupler is integrated with the flexible hose in curing mode through the hose, and the connection of the hose coupler and the flexible hose has enough tensile strength. Annular grooves are designed at the front end and the tail end of the coupler, the Y-shaped sealing ring, the metal pressure ring and the rubber sealing member are placed in the annular grooves, and the sealing flange extrudes the rubber sealing member, the metal pressure ring and the Y-shaped sealing ring by screwing the high-strength screw to generate sealing effect.

Description

technical field [0001] The invention relates to an innovation of a seabed flexible hose end connection sealing device. Background technique [0002] Marine flexible hoses are beginning to replace traditional steel marine steel pipes for transporting oil and gas and other media. Since the current marine flexible pipelines are mainly processed by high molecular polymers and metals through special processes, the joints play a role in connecting the ends of the flexible hoses. The material is made of steel, so the connection between the joints and the pipeline is relatively complicated. The traditional small-diameter marine flexible hose achieves high-pressure sealing connection through extrusion deformation, which cannot meet the high-pressure sealing connection requirements of large-diameter marine hose. This patent relates to a new type of large-diameter marine flexible hose joint, which meets the requirements for the connection strength and sealing of marine hoses. Conten...
