Abstract
The present invention discloses a kind of pressure release type petroleum pipeline deferent box cupling structure, including steel conduit, pipe box cupling, outer housing, it is characterized in that, steel conduit two ends respectively add a pipe box cupling, steel conduit inwall is provided with internal lining pipe, it is provided with closure vacuum layer between pipe box cupling and steel conduit, be socketed with outer housing outside pipe box cupling, pipe box cupling is connected with lever relief valve.
Description
Technical field
The invention belongs to petroleum pipeline technical field, more particularly to a kind of pressure release type petroleum pipeline deferent box cupling structure.
Background technology
Current oil liner oil pipe is all generally operational in the down-hole of hundreds of meters, using in built-in anticorrosion antiwear in oil pipe
Lining, can prevent sucker rod and the abrasion of tube inner wall and the internal corrosion of oil pipe.Due to well depth, oil thick down-hole in addition heat transfer temperature
Difference is big, and steel pipe thermal resistance very little, and result in by oil pipe to delivered downhole heating evaporation is that thermal loss is big, steel conduit simultaneously
It is also subjected to larger pressure, with the continuous development of heat-insulating technique, but the heat-insulating problem of vacuum oil tubing coupling never has
Solve to good, the proportion that the heat loss of tubing coupling accounts for heat loss in oil pipe pipeline is increasing, and heat insulation pressure-resistant effect is not
Too preferable.
Content of the invention
It is contemplated that overcoming the defect of prior art, a kind of pressure release type petroleum pipeline deferent box cupling structure being provided, there is knot
Structure is simple, low production cost, the feature of long service life.
In order to solve above-mentioned technical problem, the present invention provides technical scheme below：
A kind of release petroleum pipeline deferent box cupling structure, including steel conduit 1, pipe box cupling 2, outer housing 3 it is characterised in that 1 liang of steel conduit
End respectively adds a pipe box cupling 2, and steel conduit 1 inwall is provided with internal lining pipe 11, is provided with closure vacuum between pipe box cupling and steel conduit
Layer, is socketed with outer housing 3, pipe box cupling is connected with lever relief valve 4 outside pipe box cupling.
Further, lever relief valve is made up of needle valve, pressure gauge, main valve, pilot valve and connecting tube.
Further, described outer housing is tubular-shaped structures, and outer housing is made up of vinyon composite.
Further, described external be spliced by four mutually isostructural segmental arcs 31, segmental arc side wall radially respectively sets at two ends
It is equipped with an edge protector, be fixedly connected by bolt 32 between two adjacent shield sections.
Compared with prior art, the present invention has following beneficial effect：
Present configuration is simple, low production cost, long service life；By being socketed overcoat, pipe box cupling and steel in pipe box cupling appearance
The heat-insulating property that closure vacuum layer strengthens petroleum pipeline is installed between pipeline, when pipe box cupling uses, pipe box cupling is connected with lever
Formula relief valve can carry out release to the pressure in pipeline.
Brief description
Fig. 1 is the schematic diagram of pressure release type petroleum pipeline deferent box cupling structure of the present invention.
Fig. 2 is the schematic diagram of the outer housing of pressure release type petroleum pipeline deferent box cupling structure of the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated it will be appreciated that preferred reality described herein
Apply example to be merely to illustrate and explain the present invention, be not intended to limit the present invention.
As shown in Figure 1 and Figure 2, a kind of release petroleum pipeline deferent box cupling structure, including steel conduit 1, pipe box cupling 2, outer housing 3, steel
Pipeline 1 two ends respectively add a pipe box cupling 2, and steel conduit 1 inwall is provided with internal lining pipe 11, is provided with and closes between pipe box cupling and steel conduit
Close vacuum layer, outside pipe box cupling, be socketed with outer housing 3, described outer housing is tubular-shaped structures, outer housing is vinyon composite system
Become.Described external be spliced by four mutually isostructural segmental arcs 31, radially two ends are each provided with an edge protector to segmental arc side wall, two
It is fixedly connected by bolt 32 between adjacent shield section.Lever relief valve 4 is connected with pipe box cupling, lever relief valve is by aciculiform
Valve, pressure gauge, main valve, pilot valve and connecting tube are constituted.
The foregoing is only explanation embodiments of the present invention, be not limited to the present invention, for the technology of this area
For personnel, all any modification, equivalent substitution and improvement within the spirit and principles in the present invention, made etc., should be included in
Within protection scope of the present invention.
