Abstract
The utility model belongs to high-pressure rubber hose coupling technical field, disclose a kind of its technological scheme that forms this composite pipe special joint that is used in and comprised the metal-cored pipe for being provided with connector element, this metal-cored pipe inserts between the inner tube layer of the composite pipe of having removed outer glue-line and middle pressure-bearing framework layer and forms Compound pipe, on this Compound pipe, be inserted in the pipe box that is provided with filling hole, in this pipe box, be perfused with resin layer.This composite pipe special joint not only simple in structure, there is enough high voltage performances and join strength, simple and reasonable and can assemble at the construction field (site).
Description
Technical field
The utility model belongs to high-pressure rubber hose coupling technical field, relates to concretely a kind of composite pipe special joint that is used in offshore oil high-pressure delivery pipe.
Background technique
Be widely used at present the composite pipe of transfer oil, its structure include conveying high-pressure medium inner tube layer, be wrapped in the middle pressure-bearing framework layer that its outside steel wire winding braid and middle glue bond layer form and the protective layer being made up of outer glue-line forms; And the jointing of this composite pipe, in order to meet join strength and bearing strength requirement, its structure has included external pressure tube cuff structure; And in the time of this pipe hoop structure of assembling, because its pressure greatly all can cause damage to the inner tube layer of internal structure, middle pressure-bearing framework layer.Therefore this jointing not only its structure and assembling very complicated, greatly improved manufacturing cost and use cost, and these jointings must complete processing assembling in factory and are transported to building site and use.
Model utility content
The purpose of this utility model be just to provide a kind of simple in structure, can meet composite pipe special joint high pressure and join strength requirement and that can assemble at the construction field (site).
For achieving the above object, the technical solution adopted in the utility model is:
A kind of composite pipe special joint, it is characterized in that: comprise the metal-cored pipe for being provided with connector element, this metal-cored pipe inserts between the inner tube layer of the composite pipe of having removed outer glue-line and middle pressure-bearing framework layer and forms Compound pipe, on this Compound pipe, be inserted in the pipe box that is provided with filling hole, in this pipe box, be perfused with resin layer.
The additional technical feature that forms above-mentioned composite pipe special joint comprises:
---described pipe box two ends are provided with seal ring;
---on described pipe box, be provided with vent hole;
---described inner tube layer end is provided with turnup structure at described metal-cored tube end.
Composite pipe special joint provided by the utility model compared with prior art, have the following advantages: one, because the metal-cored pipe that forms this special joint inserts between inner tube layer and pressure-bearing framework layer, therefore the inner tube layer that makes to form composite pipe has formed the inner tube layer of joint, make the interior caliber of this joint consistent with the caliber of composite pipe, overcome the problem that in prior art, caliber diminishes; They are two years old, because metal-cored pipe in this special joint inserts between the inner tube layer and middle pressure-bearing framework layer of composite pipe, and be inserted in and be perfused with the resin layer that pressure-bearing framework layer and metal-cored pipe can be solidified as to integrative-structure at this section, therefore make this special joint there is high withstand voltage properties and join strength; They are three years old, because the inner tube layer end that forms composite pipe is provided with turnup structure at the metal-cored tube end of special joint, therefore not only improved the join strength between Compound pipe, main is to make composite pipe special joint identical with the inner tube layer of composite pipe, the blockage problem while effectively overcoming mass transport.
Brief description of the drawings
The radial cross section structural representation of the composite pipe special joint that Fig. 1 provides for the utility model.
Embodiment
The structure of composite pipe special joint the utility model being provided below in conjunction with accompanying drawing is described in further details.
Be illustrated in figure 1 the structural representation of the composite pipe special joint that the utility model provides.The structure that forms this composite pipe special joint is included in its end and is provided with external screw (or interior spiral shell button) and forms the metal-cored pipe 2 of connector element 1, this metal-cored pipe inserts between the inner tube layer 3 of the composite pipe 12 of having removed outer glue-line 11 and middle pressure-bearing framework layer 4 and forms Compound pipe, on this Compound pipe, be inserted in the pipe box 6 that two ends are provided with seal ring 5, on this pipe box, be provided with the filling hole 7 of epoxy resin, and be perfused with therein the resin layer 8 that makes pressure-bearing framework layer and metal-cored pipe be solidified as integrative-structure.
In the structure of above-mentioned composite pipe special joint,
---be arranged between the seal ring 5 at pipe box two ends and pipe box spiral or welding and form integrative-structure, make the cavity that inner formation can retaining ring epoxy resins;
---in order to improve the integrity of epoxy resin layer, on pipe box, be provided with vent hole 9;
---the inner tube layer end inserting in metal-cored pipe is provided with turnup structure 10 at metal-cored tube end, can be connecting another special joint time by it compression, to improve the join strength between Compound pipe, and make composite pipe special joint identical with the inner tube layer of composite pipe.
