Abstract
The utility model discloses a stopless-conveying external bypass four-way piece for an in-service oil and gas pipeline. The stopless-conveying external bypass four-way piece aims to achieve the purpose of arranging an external bypass pipeline on the in-service oil and gas pipeline under the stopless conveying condition. A reinforcing plate is arranged outside a reinforcing three-way piece of the bypass four-way piece, the side way of the bypass four-way piece is connected with the in-service oil and gas pipeline, and the middle way of the bypass four-way piece is connected with the side way of a single three-way piece. A blocking bar is arranged in an embedded barrel, a hole is formed in the wall of the embedded barrel, and the top of the barrel is connected with a plug handle provided with a sealing ring and a clamping ring groove. The single three-way piece is mounted outside the embedded barrel in a sleeved mode, and the middle way of the single three-way piece penetrates out of the hole in the embedded barrel and is connected with an external pipeline. The other side way of the bypass four-way piece is connected with a flange and a press-fitting blind plate. According to the stopless-conveying external bypass four-way piece, two three-way pipe fittings are connected to form the four-way pipe fitting connected to the in-service oil and gas pipeline, a perforated device and the external pipeline, and therefore the bypass pipeline can be externally arranged under the stopless conveying condition of the in-service oil and gas pipeline. The stopless-conveying external bypass four-way piece can save the cost of the external bypass pipeline, operation processes are simplified, beneficial measures are provided for repairing and transformation of a pipeline, and the bypass four-way piece has great application prospects under the situation that requirements for construction of stopless-conveying external bypass pipelines increase continuously.
Description
Technical field
The utility model relates to a kind of using as a servant oil and gas pipes with not drawing collateral branch's four-way outside the stopping transportation, belongs to energy source conveying technology field.
Background technique
Be accompanied by the development of modern industry and the raising of living standards of the people, also expand continuous the extension as the oil and gas pipes of major impetus energy delivery vehicles.The energy Adds User usually can be from drawing collateral branch's pipeline outside the labour oil and gas pipes.Yet in the general stopping transportation easily of labour oil and gas pipes, stopping transportation can have a strong impact on the user and produce, and causes economic loss difficult to the appraisal.In addition, in the repairing rebuilding construction of pipeline, if " shutoff " technology that " perforate " with pressure can reach effectively in conjunction with using, just can be implemented in use as a servant oil and gas pipes not the outer of collateral branch's pipeline during stopping transportation draw.
Summary of the invention
The purpose of this utility model be to provide a kind of at the labour oil and gas pipes with not drawing collateral branch's four-way outside the stopping transportation, it can be in conjunction with stopping transportation pressure perforate technology, using as a servant oil and gas pipes not during stopping transportation, draws collateral branch's pipeline outward.
Concrete technological scheme of the present utility model is as follows:
Reinforcement threeway outer circumferential face connects semicircular upper stiffening plate and lower stiffening plate; The side reduction of fractions to a common denominator of reinforcement threeway is not connected to the labour oil and gas pipes, in to lead to the side of order body threeway logical;
The embedding cylinder is provided with the base arcuate edge that cooperates pipeline to connect, and cylinder inwall bottom connects blend stop, and the barrel middle part is provided with perforate, cylinder top connection plug handle, and plug handle outer circumferential face is provided with seal ring and annular groove;
It is outside that single-body tee is sleeved on the embedding cylinder, and wherein logical perforate from the embedding cylinder passes and connects outer skirt road; Its opposite side leads to acting flange, namely buckles into the annular groove of filling in handle by flange inner peripheral surface snap ring and connects; The connection of flange other end press-fits blind plate.
The utility model is in conjunction with stopping transportation pressure perforate technology, and two tee pipe fitting windings are become to be connected to the four-way pipe fitting in labour oil and gas pipes, tapping equipment and outer skirt road, thus can be implemented in the labour oil and gas pipes not the outer of collateral branch's pipeline during stopping transportation draw.The utility model can be saved the outer cost that draws collateral branch's pipeline, and the technique that simplifies the operation is for the repairing transformation of pipeline provides useful means.Draw under the demand of collateral branch's pipe-line construction outside ever-increasing not stopping transportation, application prospect of the present utility model is full of light.

Embodiment
Further specify referring to figs. 1 through 9 couples of embodiments of the present utility model:
Embodiment:
This collateral branch four-way comprises reinforcement threeway 1, single-body tee 2, embedding cylinder 3, flange 4, press-fits blind plate 5 and outer skirt road 6:
Embedding cylinder 3 is provided with the base arcuate edge that cooperates pipeline to connect, cylinder inwall bottom welding blend stop 31, and the barrel middle part is provided with rectangle opening 32, cylinder welded top plug handle 33, plug handle 33 outer circumferential faces are provided with seal ring 34 and annular groove 35;
Single-body tee 2 is sleeved on embedding cylinder 3 outsides, and wherein logical rectangle opening 32 from embedding cylinder 3 passes and weld outer skirt road 6; Its opposite side leads to acting flange 4, namely buckles into the annular groove 35 of filling in handle 33 by flange 4 inner peripheral surface snap rings and connects; The connection of flange 4 other ends press-fits blind plate 5.
The function of this collateral branch each parts of four-way is as follows:
Lower stiffening plate 7 and upper stiffening plate 8 can guarantee the requirement of strength after reinforcement threeway 1 perforate, increase the intensity of docking with single-body tee 2.Embedding cylinder 3 can guarantee the integrity of this collateral branch four-way pipeline, is convenient to pigging and the detection of pipeline.Flange 4 can guarantee the complete detachability of facility in order to connect the not press and open holes facility of stopping transportation, does not leave over excessive too much auxiliary equipment.Press-fit blind plate and be used for press-fiting and sealing embedding cylinder 3, be convenient to anti-corrosion material and directly act on its surface.
