The utility model discloses a kind of tubing coupling, including box cupling body, a cylindrical drum is socketed in the box cupling body outer surface, heat insulation cylinder is provided between the cylinder tube inner surface and box cupling body, the heat insulation cylinder is coated on box cupling body outer surface, the box cupling body two ends are provided with elastic flange, the heat insulation cylinder two ends and the elastic flange against formation containing vacuum layer between heat-insulated tube outer surface and cylinder tube inner surface.Heat insulation cylinder is set by the outer surface of box cupling in the utility model, 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.

Description

A kind of tubing coupling
Technical field
The utility model is related 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 underground, because well depth, the thick heat transfer temperature difference of underground in addition of oil are big, And steel pipe thermal resistance is small, cause thermal loss big.It is to cause the main original of above mentioned problem that the heat-insulating property of oil pipe and box cupling is relatively low Cause, is that this this oil pipe and box cupling must be using heat-proof quality superior insulated tubings and heat-insulated box cupling.
Utility model content
In order to overcome the problem of existing technical deficiency, the utility model provides a kind of tubing coupling.
What the technical solution of the utility model was realized in:A kind of tubing coupling, including box cupling body, in the box cupling Body outer surface is socketed a cylindrical drum, and heat insulation cylinder, the heat insulation cylinder are provided between the cylinder tube inner surface and box cupling body Box cupling body outer surface is coated on, the box cupling body two ends are provided with elastic flange, and the heat insulation cylinder two ends are convex with the elasticity Edge against, between heat-insulated tube outer surface and cylinder tube inner surface formed containing vacuum layer.
Preferably, the cylindrical drum is provided with and vacuumizes hole, and vacuum hole a diameter of 0.1-2cm.
Preferably, the diameter with diameter greater than cylindrical drum of the elastic flange.
The utility model beneficial effect is:Heat insulation cylinder is set by the outer surface of box cupling in the utility model, is solved Problems of the prior art, and, vacuum layer is formed between heat insulation cylinder, elastic flange and cylindrical drum, insulation can be played Effect.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model tubing coupling;
In figure:1 box cupling body, 2 elastic flanges, 3 cylindrical drums, 4 vacuum layers, 5 heat insulation cylinders.
Specific embodiment
The utility model 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, it is socketed a circle in the outer surface of box cupling body 1 Column casing 3, is provided with heat insulation cylinder 5 between the inner surface of the cylindrical drum 3 and box cupling body 1, the heat insulation cylinder 5 is coated on box cupling body 1 Outer surface, the two ends of box cupling body 1 are provided with elastic flange 2, and the two ends of the heat insulation cylinder 5 and the elastic flange 2 are against heat-insulated Containing vacuum layer is formed between 5 outer surfaces of cylinder and the inner surface of cylindrical drum 3.
Cylindrical drum 3 described in the utility model is provided with and vacuumizes hole, and vacuum hole a diameter of 0.1-2cm, it is described true Emptying aperture is connected with vaccum-pumping equipment, vacuumizes after finishing, it is necessary to stopper vacuum hole with piston, holding vacuum state plays insulation Effect.
The diameter with diameter greater than cylindrical drum of elastic flange 2 in the utility model, such setting can guarantee that elastic flange 2 It is brought into close contact with the both sides of cylindrical drum 3, forms confined space.
Heat insulation cylinder is set by the outer surface of box cupling in the utility model, 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 utility model is described with reference to its specific embodiment.But it is clear that still can be with Various modifications and alterations are made without departing from spirit and scope of the present utility model.Therefore, specification is considered as illustrative And it is nonrestrictive.
