Abstract
The utility model discloses a kind of petroleum pipeline with spiral choke apparatus, described pipeline cone structure, heavy caliber one end is connected with big-diameter pipeline, another small-bore one end is connected with small-caliber pipeline, interlock in described buffering pipe and be provided with spiral choke apparatus, described spiral choke apparatus is volute, and the screw diameter of described volute increases from heavy caliber one end gradually to small-bore one end.The buffering petroleum pipeline of the utility model cone structure, the oil entered under can making high pressure is well cushioned, and the effect of flow-disturbing is played in the setting of spiral choke apparatus, pressure when more effectively cushioning oil from extra heavy pipe to tubule and impact force.Thus effectively prevent the oil leakage problem of thickness joint.
Description
Technical field
The utility model relates to a kind of for the transition petroleum pipeline between thickness pipeline.
Background technique
Oil transport pipeline (also claiming pipeline, pipeline) is made up of oil pipe and annex thereof, and according to the needs of technological process, be equipped with corresponding oil pump unit, design and installation becomes a complete pipe-line system, unloads in order to complete oil plant and defeatedly turns task.When needs oil transport pipeline is from coarse to fine, due to the impact that pipeline attenuates, the pressure being easy to make middle joint to hold to can't stand liquid and the problem such as out to leak.
Model utility content
The technical problems to be solved in the utility model overcomes existing defect, provides and can effectively prevent oil pressure from changing the buffering petroleum pipeline with spiral choke apparatus causing leakage.
The purpose of this utility model carrys out specific implementation by the following technical programs:
A kind of buffering petroleum pipeline with spiral choke apparatus, described pipeline cone structure, heavy caliber one end is connected with big-diameter pipeline, another small-bore one end is connected with small-caliber pipeline, interlock in described buffering pipe and be provided with spiral choke apparatus, described spiral choke apparatus is volute, and the screw diameter of described volute increases from heavy caliber one end gradually to small-bore one end.
Preferably, the spacing of neighbouring two spiral choke apparatus is 8-12cm.
Preferably, described volute is evenly crisscross arranged between buffering pipe inner arm, forms meter-shape structure staggered up and down.
The beneficial effects of the utility model:
The buffering petroleum pipeline of the utility model cone structure, the oil entered under can making high pressure is well cushioned, and the effect of flow-disturbing is played in the setting of spiral choke apparatus, pressure when more effectively cushioning oil from extra heavy pipe to tubule and impact force.Thus effectively prevent the oil leakage problem of thickness joint.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:
Fig. 1 is the buffering petroleum pipeline plan structure schematic diagram of the utility model with spiral choke apparatus;
Fig. 2 is the generalized section of Fig. 1 along A-A direction.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
embodiment 1:
A kind of buffering petroleum pipeline 3 with spiral choke apparatus, described pipeline 3 cone structure, heavy caliber one end is connected with big-diameter pipeline 1, another small-bore one end is connected with small-caliber pipeline 2, interlock in described buffering pipe and be provided with spiral choke apparatus, described spiral choke apparatus is volute 4, and the screw diameter of described volute increases from heavy caliber one end gradually to small-bore one end.The spacing of neighbouring two spiral choke apparatus is 8-12cm.Described volute is evenly crisscross arranged between buffering pipe inner arm, forms meter-shape structure staggered up and down.
When oil carries out thin pipe by extra heavy pipe road, through buffering petroleum pipeline, under the flow-disturbing effect of spiral choke apparatus, decrease instantaneous pressure and the impact force of thin pipe.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
