Description

A kind of clean type tubing coupling component
Technical field
The utility model relates to tubing coupling technical fields, and in particular to a kind of clean type tubing coupling component.
Background technique
Tubing coupling is one kind of oilfield wellbore tools, is mainly used for the connection of oil pipe.The structure of tubing coupling is box cupling Body both ends vehicle has screw thread, is connected two oil pipes with the screw thread at box cupling body both ends.The shortcomings that this traditional tubing coupling, exists In: two between oil pipe end and tubing coupling there are annular gap, in long-term use process, can be hidden in the annular gap and receive dirt Dirt is directly contacted with tubing coupling, therefore, can be caused to corrode to tubing coupling, be reduced the service life of tubing coupling, even if Disassemble maintenance, it is also difficult to clear up the dirt of its inner wall.
Utility model content
The purpose of this utility model is that in view of the drawbacks of the prior art and insufficient, provide that a kind of structure is simple, design is closed Reason, clean type tubing coupling component easy to use.
In order to achieve the above purposes, the technical solution adopted by the utility model is: it include outer box cupling, it is oil pipe, interior box cupling, outer Screw thread, internal screw thread, burr, sealing ring annular groove, sealing ring;The end outer wall of the oil pipe is provided with external screw thread, the end of oil pipe Portion's inner wall circumference uniform distribution is jagged, and internal screw thread is provided on the inside of burr, and the both ends of interior box cupling pass through internal screw thread with oil pipe respectively Connection, the outer wall of interior box cupling are provided with sealing ring annular groove, are equipped with sealing ring in sealing ring annular groove;The outer box cupling and two The end of oil pipe is connected by external screw thread.
Preferably, being symmetrical arranged there are two the outer wall settings of the interior box cupling, and the sealing ring of outward opening Slot.
Preferably, the sealing ring annular groove is welded on the outer wall of interior box cupling.
Preferably, the outer box cupling is convex character shape structure.
When the utility model operates, first the end of an oil pipe and one end of interior box cupling and outer box cupling are screwed on, interior box cupling It is screwed in place, that is, is threaded to sealing ring ring groove position, outer box cupling is first spun on the outer wall of the oil pipe completely;Then by another oil pipe It is spun on the other end of interior box cupling, outer box cupling is finally threaded to the right to the outer wall of the oil pipe, overlaps outer box cupling by two oil pipes;It is close Seal annular groove can not only install sealing ring, but also play the position-limiting action to oil pipe;The reinforcing that the outer box cupling plays junction is made With;It is sealed between the end of oil pipe and interior box cupling using sealing ring, makes crude oil that must not leak outside, after using one end time, tieed up Shield: unscrewing outer box cupling to side, exposes interior box cupling, then the box cupling in the back-out of the end of oil pipe, precession repeatedly, and at this moment burr can be clear The dirt of Zang Na between brush oil pipe and interior box cupling.
After adopting the above structure, the utility model is the beneficial effects are as follows: a kind of clean type described in the utility model Tubing coupling component clears up dirt using ejected wash water without disassembling completely, and whens spinning in and out clears up dirt automatically, uses the longevity Life length, is connected firmly, seals, and the utility model has many advantages, such as that structure is simple, setting is reasonable, low manufacture cost.
Detailed description of the invention
Fig. 1 is the structure chart of the utility model;
Fig. 2 is the structure chart of the utility model outer box cupling and interior box cupling;
Fig. 3 is the portion the A enlarged drawing in Fig. 1.
Description of symbols:
Outer box cupling 1, oil pipe 2, interior box cupling 3, external screw thread 4, internal screw thread 5, burr 6, sealing ring annular groove 7, sealing ring 8.
Specific embodiment
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.
Referring to such as Fig. 1 --- shown in Fig. 3, present embodiment adopts the following technical scheme that it includes outer box cupling 1, oil Pipe 2, interior box cupling 3, external screw thread 4, internal screw thread 5, burr 6, sealing ring annular groove 7, sealing ring 8;The end outer wall of the oil pipe 2 is set It is equipped with external screw thread 4, the inner wall of end circumference uniform distribution jagged 6 of oil pipe 2, the inside of burr 6 is provided with internal screw thread 5, interior box cupling 3 Both ends are connect with oil pipe 2 by internal screw thread 5 respectively, and the outer wall of interior box cupling 3 is provided with sealing ring annular groove 7, peace in sealing ring annular groove 7 Equipped with sealing ring 8;The outer box cupling 1 is connect with the end of two oil pipes 2 by external screw thread 4.
Preferably, being symmetrical arranged there are two the outer wall settings of the interior box cupling 3, and the sealing ring of outward opening Slot 7.
