Description
Technical field
The utility model is related to pipe fitting technical field, especially a kind of split type petroleum pipeline pipe nipple.
Background technology
Tubing nipple is the mechanical part of oil pipe connection in oil development, is mainly used in the connection of oil pipe.In petroleum transportation
In, tubing nipple plays connected pipes, and because multiple petroleum pipelines are threadedly coupled with pipe nipple, certainly existing needs rotation one
The larger petroleum pipeline of individual length, this operation is arduously dangerous, and easily connection occurs built on the sand.
Utility model content
The utility model in view of the shortcomings of the prior art, proposes a kind of split type petroleum pipeline pipe nipple, easily clever structure, behaviour
Make, good airproof performance.
In order to realize above-mentioned utility model purpose, the utility model provides following technical scheme：A kind of split type petroleum pipeline
Pipe nipple, including inner and outer tubes, inner tube one end are external thread structure, and the other end is plugged in one end of outer tube vertically, outer tube
The other end be provided with external thread structure；Inner tube plugs end periphery and is provided with elastic spacing projection, and it is convex that outer tube is provided with correspondence elastic spacing
The groove and spacing hole for rising.
Further, the outer tube wall is provided with sealing ring, and it is solid with outer tube wall sealing that the inner tube plugs the sealed circle in end
It is fixed.
Further, the outer tube lateral wall is provided with enhancement layer.
Compared with prior art, the utility model has advantages below：Pipe nipple is divided into two and plugs butted part, grasped
Make easy, install easy, good airproof performance.
Brief description of the drawings
Fig. 1 is the cross section structure diagram of the split type petroleum pipeline pipe nipple of the utility model.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings, the description of this part be only it is exemplary and explanatory,
There should not be any restriction effect to protection domain of the present utility model.
As shown in figure 1, a kind of split type petroleum pipeline pipe nipple, including inner tube 1 and outer tube 2, the one end of inner tube 1 is external screw thread knot
Structure, the other end is plugged in one end of outer tube 2 vertically, and the other end of outer tube 2 is provided with external thread structure；It is outer that inner tube 1 plugs end
It is provided with elastic spacing projection 11 week, outer tube 2 is provided with the raised groove and spacing hole 21 of correspondence elastic spacing.
Inner tube 1 and outer tube 2 before docking, outside termination connect petroleum pipeline respectively, convenient and swift due to being threaded connection,
It is easily operated；Then inner tube 1 and outer tube 2 are carried out into Butt sealing, reaches two petroleum pipelines and quickly connect.
The inwall of outer tube 2 is provided with sealing ring 3, and the inner tube 1 plugs the sealed circle 3 in end and fixed with the inner wall sealing of outer tube 2, seals
Circle 3 causes to be effectively sealed against between the inner tube 1 docked and outer tube 2.
The lateral wall of outer tube 3 is provided with enhancement layer 4, improves the intensity of whole pipe nipple.
The above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
