Abstract
Disclosed is a novel whole pipeline. The novel whole pipeline comprises a cylindrical pipeline body, a three-jaw nut, a shaft elastic check ring and a clamp ring, the three-jaw nut is arranged at one end of the pipeline body, a sealing washer is disposed on the inner diameter of the other end of the pipeline body, the clamp ring sleeves one end of the pipeline body in a clamping mode, the three-jaw nut sleeves the clamp ring, the shaft elastic check ring is arranged between the three-jaw nut and the clamp ring, and a section of the pipeline body, which is close to the three-jaw nut and the clamp ring, is provided with a limiting boss. By means of the technical scheme, main problems that when whole pipelines in the prior art move downwards, three-jaw nuts and clamp rings are prone to fall off along pipeline bodies, and installation and operation are affected can be solved.
Description
Technical field
The utility model belongs in oil field fixes control valve line apparatus technical field, relates to a kind of novel overall pipeline.
Background technology
In recent years, along with the development of drilling well, oil recovery technique, bore, adopt in process, thereby usually need control or transfer line to control the duty of downhole tool or the data that transmission downhole instrument gathers for transmitting hydraulic pressure or optical, electrical signal, the pipeline of these types often needs to use overall pipeline to be fixed on tubing string.
Overall pipeline is to adopt high strength alloy steel to forge to form, for high-pressure discharge pipeline, and intake pipeline, auxiliary flow pipeline, interim liquid flowing line, in the pipeline that under well logging pipeline and other high pressure operating mode, conveying liquid flows.Entirety pipeline is according to environment for use difference, and its rated pressure is also different, generally has 42MPa, 70MPa and 105MPa, and operating temperature is-29 DEG C ~ 121 DEG C.
Conventionally the on-the-spot overall pipeline using, structure as shown in Figure 1, comprises pipeline body 1, is arranged on three-jaw nut 2, circlip for shaft 3 and the collar 4 of pipeline body 1 one end; The other end inner end diameter of described pipeline body 1 is provided with seal washer 5; Wherein, collar 4 is fastened on the end of described pipeline body 1 one end, and described three-jaw nut 2 is set on described collar 4, and described collar 4 is provided with circumferential groove, and described circlip for shaft 3 is embedded in described groove.The middle part of described pipeline body 1 is cylindrical.
Although the overall pipeline of said structure has used for many years,, in use, overall pipeline is lowered in process, and three-jaw nut and collar easily drop along pipeline body, very inconvenient to operating personnel's fitting operation.
Therefore, how addressing the above problem, is the problem that those skilled in the art will study.
Summary of the invention
The utility model provides a kind of novel overall pipeline, and its object is mainly to solve in prior art, and overall pipeline is being lowered in process, and three-jaw nut and collar easily drop along pipeline body, affect the problem of fitting operation.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel overall pipeline, comprises columniform pipeline body, is arranged on three-jaw nut, circlip for shaft and the collar of pipeline body one end; The other end inner end diameter of described pipeline body is provided with seal washer; Wherein, collar is fastened on the end of described pipeline body one end, and described three-jaw nut sleeve is located on described collar, on described pipeline body, in the section near three-jaw nut and collar, is provided with positive stop lug boss.
Related content in technique scheme is explained as follows:
1, in such scheme, described positive stop lug boss is truncated cone-shaped near a side of collar, and described positive stop lug boss is taper type away from a side of collar.
2,, in such scheme, described positive stop lug boss is greater than the external diameter of described collar near the external diameter of collar one side.
3,, in such scheme, the outer edge surface of described overall pipeline body is provided with antirust coat.
4,, in such scheme, on described collar, along being circumferentially with groove, described circlip for shaft is embedded in described groove.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
1, because the utility model is provided with positive stop lug boss at pipeline body near on collar and three-jaw nut one section, this positive stop lug boss can be by fixing within the specific limits to three-jaw nut and collar, handled easily personnel operation, installs.Solved in prior art, overall pipeline is being lowered in process, and three-jaw nut and collar easily drop along pipeline body, affect the problem of fitting operation.
2, due to the design of the utility model positive stop lug boss structure, the size of collar can be unified, do not need to customize in addition collar, save cost.
Brief description of the drawings
Accompanying drawing 1 is integral tube line structure schematic diagram in prior art;
Accompanying drawing 2 is the utility model structural representation.
detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Embodiment:
As shown in Figure 2, a kind of novel overall pipeline, comprises columniform pipeline body 1, is arranged on three-jaw nut 2, circlip for shaft 3 and the collar 4 of pipeline body one end; The other end inner end diameter of described pipeline body 1 is provided with seal washer 5; Wherein, collar 4 is fastened on the end of described pipeline body 1 one end, and described three-jaw nut 2 is set on described collar 4, and described circlip for shaft 3 is arranged between described three-jaw nut 2 and collar 4; On described collar 4, along being circumferentially with groove (not shown), described circlip for shaft 3 is embedded in described groove.
On described pipeline body 1, in the section near three-jaw nut 2 and collar 4, be provided with positive stop lug boss 6.
Described positive stop lug boss 6 is truncated cone-shaped near a side of collar 4, and described positive stop lug boss 6 is taper type away from a side of collar 4.
Described positive stop lug boss 6 is greater than the external diameter of described collar 4 near the external diameter of collar 4 one sides.
The outer edge surface of described overall pipeline body 1 is provided with antirust coat.
Because the utility model is provided with positive stop lug boss 6 at pipeline body 1 near on collar 4 and three-jaw nut 2 one section, this positive stop lug boss 6 can be by fixing within the specific limits to three-jaw nut 2 and collar 4, handled easily personnel operation, installs.The design of positive stop lug boss 6 structures, can unify the size of collar 4, does not need to customize in addition collar, has saved cost.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
