Abstract
The invention discloses an oil pipe coupling which comprises a coupling body, wherein the outer surface of the coupling body is in sleeve joint with a cylinder; a heat insulation cylinder is arranged between the inner surface of the cylinder and the coupling body; the heat insulation cylinder coats the outer surface of the coupling body; elastic flanges are arranged at the two ends of the coupling body; the two ends of the heat insulation cylinder are placed against the elastic flanges; and a closed vacuum layer is formed between the outer surface of the heat insulation cylinder and the inner surface of the cylinder. In the invention, since a heat insulation cylinder is arranged on the outer surface of the coupling, the problems of the prior art are solved; and moreover, a vacuum layer is formed among the heat insulation cylinder, the elastic flanges and the cylinder and can realize a heat preservation effect.
Description
Technical field
The present invention relates to petroleum pipeline technical field, more particularly to a kind of tubing coupling.
Background technology
The oil pipe for using at present is generally operational in thousands of meters of down-hole, as well depth, the thick heat transfer temperature difference of down-hole in addition of oil are big,
And steel pipe thermal resistance is little, cause thermal loss big.The relatively low main original for being to cause the problems referred to above of the heat-insulating property of oil pipe and box cupling
Cause, is that this this oil pipe and box cupling must adopt the superior insulated tubing of heat-proof quality and heat-insulated box cupling.
Content of the invention
In order to overcome the problem of existing technical deficiency, the present invention provides a kind of tubing coupling.
The technical scheme is that and be achieved in that：A kind of tubing coupling, including box cupling body, in the box cupling body
Outer surface is socketed a cylindrical drum, is provided with heat insulation cylinder between the cylinder tube inner surface and box cupling body, the heat insulation cylinder cladding
In box cupling body outer surface, the box cupling body two ends are provided with elastic flange, and the heat insulation cylinder two ends are supported with the elastic flange
Lean on, between heat-insulated tube outer surface and cylinder tube inner surface, form containing vacuum layer.
Preferably, the cylindrical drum is provided with evacuation hole, and a diameter of 0.1-2cm of vacuum hole.
Preferably, the diameter with diameter greater than cylindrical drum of the elastic flange.
Present invention has the advantages that：In the present invention, heat insulation cylinder is arranged by the outer surface in box cupling, solve prior art
Present in problem, and, between heat insulation cylinder, elastic flange and cylindrical drum formed vacuum layer, insulation can be played a part of.
Description of the drawings
Fig. 1 is the structural representation of tubing coupling of the present invention；
In figure：1 box cupling body, 2 elastic flanges, 3 cylindrical drum, 4 vacuum layer, 5 heat insulation cylinders.
Specific embodiment
The present invention is described further in conjunction with the accompanying drawings and embodiments.
As shown in figure 1, a kind of tubing coupling, including box cupling body 1, is socketed a circle in 1 outer surface of box cupling body
Column casing 3, is provided with heat insulation cylinder 5 between 3 inner surface of the cylindrical drum and box cupling body 1, the heat insulation cylinder 5 is coated on box cupling body 1
Outer surface, 1 two ends of box cupling body are provided with elastic flange 2, and 5 two ends of the heat insulation cylinder and the elastic flange 2 are against heat-insulated
Containing vacuum layer is formed between 5 outer surfaces of cylinder and 3 inner surface of cylindrical drum.
Heretofore described cylindrical drum 3 is provided with evacuation hole, and a diameter of 0.1-2cm of vacuum hole, the vacuum hole
Being connected with vaccum-pumping equipment, after evacuation is finished, needs vacuum hole to be stoppered with piston, keep vacuum state, play the work of insulation
With.
The diameter with diameter greater than cylindrical drum of elastic flange 2 in the present invention, such setting can guarantee that elastic flange 2 with circle
3 both sides of column casing fit tightly, and form confined space.
In the present invention, heat insulation cylinder is arranged by the outer surface in box cupling, problems of the prior art are solved, and,
Vacuum layer is formed between heat insulation cylinder, elastic flange and cylindrical drum, insulation can be played a part of.
In this description, the present invention is described with reference to its specific embodiment.But it is clear that can still make
Various modifications and alterations are without departing from the spirit and scope of the present invention.Therefore, description is considered as illustrative rather than limit
Property processed.
