Abstract
The utility model relates to a conic clamp for an anode two-piece set of a sleeve pipe bracelet, which mainly solves the problems that the connectivity of the existing anode and the existing sleeve pipe and the ability of external force resistance of the anode are bad. The utility model is characterized in that a sleeve pipe (1) is coated with an inner ring (4) which is provided with a step (2) on one end, an opening (3) transversely, and a screw thread (8) on the inner wall. The outside of the inner ring (4) is connected with an outer ring (6) of which one end is provided with a tapered hole (5) inside through a screw thread. 4-8 gaps (7) are arranged on the step (2). The utility model has the characteristicsof good connecting reliability between the anode and the sleeve pipe, strong ability of the external force resistance, and easy construction.
Description
Technical field:
The utility model relates to the used anticorrosion anchor clamps in oil field oil water well annular tube field, especially sleeve pipe bracelet anode Two Piece Set tapered fixture.
Background technology:
All to be lowered to sleeve pipe in the oil field in to oil and water well shaft building process.It is the protection borehole wall that telescopic mainly acts on, and sealing and separate each oil-water-layer reaches the purpose of oil and water well layer mining, zonation test, zonal injection, separate zone stimulation.And sleeve pipe adds down-hole high temperature, highly compressed influence for a long time in down-hole and process that resident fluid contacts, and sleeve pipe is easy to produce corrosion failure.In recent years; adopt the anodic protection sleeve pipe; but this protection is used to connect anode and the fixed structure is reasonable inadequately; make connectivity and anode external force resistance ability between anode and the sleeve pipe; cause the protective casing ability drop, construction simultaneously is complicated, has increased labor strength; reduce working efficiency, influenced the profit well yield.
The utility model content:
In order to overcome the connectivity between existing anode and the sleeve pipe and the deficiency of anode external force resistance ability, the utility model provides a kind of sleeve pipe bracelet anode Two Piece Set tapered fixture, and these anchor clamps have the characteristics that connection reliability is good, anode external force resistance ability reaches easy construction by force between anode and the sleeve pipe.
The technical solution of the utility model is: this sleeve pipe bracelet anode Two Piece Set tapered fixture comprises sleeve pipe, and sleeve pipe is with an end band stage outward and the interior ring of threaded on opening and the inwall (8) is laterally arranged, and interior ring is outer to be connected with the outer shroud that tapered hole is arranged in the end by screw thread.4-8 gap arranged on the stage.
4-8 gap arranged on the above-mentioned stage; Threaded on the interior ring inwall.
The beneficial effect that the utlity model has is: this anchor clamps owing to be with outside sleeve pipe on the transverse belt opening inwall encircle in threaded; interior ring is outer to be connected with outer shroud by screw thread; when tightening outer shroud; screw thread in making on the ring inwall is eaten into sleeve pipe; anchor clamps and telescopic bonding force have so just been increased; thereby electrode and telescopic connection reliability and anode external force resistance ability have been strengthened; improved the protective casing ability; make construction simple simultaneously; reduced labor strength; improved working efficiency, and simple in structure.
Description of drawings:
Accompanying drawing 1 is the utility model structure sectional view.
1-sleeve pipe among the figure, 2-stage, ring in the 3-opening, 4-, 5-tapered hole, 6-outer shroud, 7-gap, 8-screw thread.
Embodiment:
Below in conjunction with accompanying drawing will the utility model is described in further detail: by shown in Figure 1, this sleeve pipe bracelet anode Two Piece Set tapered fixture comprises sleeve pipe 1, ring 4 in sleeve pipe 1 outer being with, interior ring 4 one ends have stage 2,4 gap 7 are arranged on the stage 2, interior ring 4 laterally has opening 3, on interior ring 4 inwalls screw thread 8 is arranged, be connected with outer shroud 6 by screw thread outside the interior ring 4, in outer shroud 6 one ends tapered hole 5 arranged, interior ring 4 is enclosed within on the sleeve pipe, when rotation outer shroud 6, owing on the interior ring 4 transverse opening 3 is arranged, when interior ring 4 passed through the internal tapered hole 5 of outer shroud 6, ring 4 shrank in making, screw thread 8 on interior ring 4 inwalls is eaten into sleeve pipe, so just increase anchor clamps and telescopic bonding force, thereby strengthened electrode and telescopic connection reliability and anode external force resistance ability, improved the protective casing ability, make construction simple simultaneously, reduce labor strength, improved working efficiency, and simple in structure; Gap 7 is used for connection electrode, the intensifier electrode stability.
Claims (2)
1, a kind of sleeve pipe bracelet anode Two Piece Set tapered fixture, comprise sleeve pipe (1), it is characterized in that: the outer interior ring (4) that is with an end band stage (2) and threaded (8) on opening (3) and the inwall are laterally arranged of sleeve pipe (1), interior ring (4) is outer to be connected with the outer shroud (6) that tapered hole (5) are arranged in the end by screw thread.
