Abstract

Disclosed is a union coupling device, which relates to a pipeline connecting tool after perforating and damaging nonmetallic pipelines in oilfield production. The union coupling device which comprises two correspondingly arranged portions is characterized in that two assorted pipeline connectors are structured symmetrically, the outer end of each pipeline connector is provided with a press cap, a pipeline hole is disposed in the middle of the press cap, the outer end of a round pipe-shaped packing is locked with the press cap, and the inner wall of the packing is equipped with pipe threads. The utility model is capable of coupling breakages of pipelines without digging up or replacing the pipelines, thereby having the advantages of light workload, small labor intensity, less time and material consumption, low production cost and slight impact on production of an oil-water well. Moreover, the utility model is capable of performing a certain compensation function of expansion and contraction on pipelines.

Description

A kind of union coupling
Technical field
The utility model relates in a kind of field produces the nonmetal pipeline damaged rear line of boring a hole and connects apparatus.
Background technique
In field produces, promoted the use of a large amount of nonmetal pipelines, advantages such as every length is at 8-10 rice, connects by union, and that this pipeline has is anticorrosive, less scaling, construction is simple and direct, but because the local in recent years construction scale that strengthens, some constructions on pipeline etc. are often arranged, the damaged situation of pipeline takes place easily, in case damaged, needing to dig out one or two pipelines changes, workload is big, and labor intensity is big, has influenced the production of oil/water well.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of union coupling, and big to solve the damaged replacing of prior art pipeline workload, labor intensity is big, influences problems such as oil/water well production.
The technical solution of the utility model is achieved in that two corresponding settings of supporting pipe connector, symmetrical configuration, the outer end of two pipe connectors is provided with pressure cap, establish the pipeline hole in the middle of the pressure cap, tubular shape packing outer end and pressure cap fasten, and the packing inwall is provided with pipe thread.
Adopting good effect of the present utility model is to find the pipeline breakage, need not dig out or change pipeline, only implements to connect at the pipeline breakage spot, and workload is little, labor intensity is little, save time, material-saving, cost of production are low, very little to the production influence of oil/water well.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified:
Accompanying drawing 1 is the utility model structural representation;
1 preceding former pipeline, 2 pressure caps, 3 pipe thread, 4 stuffing box packing, 5 sizing vats, 6 new pipelines, the former pipeline in 7 backs among the figure.
Embodiment
As shown in the figure; Pressure cap (2) is a bottle cap shape structure, establishes the pipeline hole in the middle of the pressure cap (2), and tubular shape sizing vat (5) outer end and pressure cap (2) fasten, and packing (5) inwall is provided with pipe thread (3), and stuffing box packing (4) places the chamber in the sizing vat (5).
In the working procedure, after the pipeline breakage takes place, pipeline is carried out digging out the depot siding place after pipeline purging, the emptying, and elder generation cuts preceding former pipeline (1), back former pipeline (7) interface according to the length of the new pipeline of the utility model flat with cutting machine, former pipeline (1), back former pipeline (7) before sizing vat (5) cover being installed to again, to last new pipeline (6), again sizing vat 5 is enclosed within on the new pipeline (6), behind the dependence pipe thread seal, can adds packing 4 on both sides, add stuffing box packing (4), compress pressure cap (2) and get final product.The journey that flows backwards is at last carried out pressure testing to pipeline, then can put into production as non-leakage.The utility model also can play certain flexible compensation effect to pipeline.

Claims (1)

1, a kind of union coupling is made up of two-part that correspondence is provided with, and it is characterized in that two supporting pipe connector symmetrical configuration, the outer end of two pipe connectors is provided with pressure cap, establish the pipeline hole in the middle of the pressure cap, tubular shape packing outer end and pressure cap fasten, and the packing inwall is provided with pipe thread.
