Example Embodiment

[0018] The present invention will be described in detail below with reference to the drawings and examples.

[0019] Such as figure 1 , 2 As shown, the present invention includes the front end of the joint 1, the outer sleeve of the joint 2, the rear end of the joint 3, the fixing ring 4, the fixing sleeve 5, the fastening flange 6, the sealing flange 7, the holding sleeve 8, the clamping block 9, and the insulating pad 10. O-ring 11, sealing ring 12, steel ring 13, steel sleeve 14, and tapered sleeve 15. Put the sealing flange 7, the sealing ring 12, the steel ring 13, the sealing ring 12, the steel sleeve 14, the tapered sleeve 15, and the joint rear end 3 into the outer coating layer of the composite hose in turn, and pass the high-strength bolt through the sealing method The through hole of the flange 7 is screwed into the threaded hole of the rear end 3 of the joint, and the sealing ring 12 is deformed to achieve sealing; the tapered sleeve 15, the steel sleeve 14, the s...

Abstract

The invention relates to a glue injection joint accessory for a large-diameter composite hose. The glue injection joint accessory comprises a joint front end, a joint jacket, a joint rear end, a fixing ring, a fixing sleeve, a fastening flange, a seal flange, a holding sleeve, a clamping block, an insulating pad, an O-shaped ring, a seal ring, a steel ring, a steel bushing and a conical sleeve. By components mechanically fixed to each layer of the composite hose, mechanical fixation between each layer of the composite hose and the joint accessory can be realized, sealing of an inner pressure seal layer, an outer coating layer and a middle coating layer of the composite hose is guaranteed, and possibility of permeation of a joint is lowered; by the aid of exhaust valves in two specifications, a solution to discharge of permeation gas when the exhaust valve at the front end of the joint is in blockage is realized; owing to the insulating pad, corrosion is avoided, and strength and airtightness of the composite hose are guaranteed.

Description

[0001] technical field [0002] The invention relates to a pipeline joint fitting, in particular to a glue injection joint fitting used for a marine large-diameter composite hose. Background technique [0003] Traditional and conventional submarine pipelines are mainly made of steel pipes, and the hoses have long relied on foreign imports. The overall construction, installation and follow-up maintenance work cycle is long and expensive. The advantages of strong adaptability, fast laying speed, low cost, not easy to deposit wax and can be reused have begun to be applied to the transportation of subsea oil, gas and water. Due to the limited continuous length of the hose pipeline, each hose end must be equipped with Joint fittings are used to ensure the connection between pipelines. However, with the continuous improvement of domestic composite hose production technology and the trend of offshore oil and gas exploration to the deep sea, composite hoses have broad prospects for ...
