A device for reducing oil pressure in pipeline

Abstract

The invention provides a device for reducing petroleum pressure in a pipeline. The device comprises an inner gear which is arranged on the inner side wall of the pipeline and is used for scraping offoil sediments, a driving mechanism which is used for driving the inner gear to rotate, and a conversion mechanism which is connected with the driving mechanism and used for controlling the inner gearto rotate, the driving mechanism and the conversion mechanism are fixedly arranged on the inner wall of the pipeline, the inner side wall of the pipeline is further provided with a rotating mechanismwhich is used for driving the conversion mechanism to work, the rotating mechanism is arranged on the side opposite to the conversion mechanism, the driving mechanism is connected with a power mechanism which is arranged on the outer side of the pipeline, and the rotating mechanism is connected with a driving rotating disc which is arranged on the outer side of the pipeline. According to the provided device for reducing the petroleum pressure in the pipeline, when the flow speed of the petroleum in the pipeline is too high or too low, the pressure of the petroleum to the pipe wall can be reduced, and the problem that in the flowing process of the petroleum in a zigzag pipeline part, the pressure applied on the petroleum pipeline is too large is solved.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a device for reducing oil pressure in pipelines. Background technique [0002] Petroleum, also known as crude oil, is stored in parts of the upper crust, and its main components are mixtures of various alkanes, cycloalkanes, and aromatic hydrocarbons. Petroleum is mainly used as fuel oil and gasoline, and is also a raw material for many chemical industry products such as solutions, fertilizers, pesticides and plastics. Oil pipelines are pipelines that transport oil from mining sites or processing plants to urban oil distribution centers or industrial enterprise users, also known as oil pipelines. The use of oil pipelines to transport oil is the only way to transport large quantities of oil on land. In the total length of pipelines in the world, oil pipelines account for about half of the number. [0003] At present, the valves used on high-pressure pipelines such as oil pipel...

Problems solved by technology

[0004] The purpose of the present invention is to provide a device for reducing the oil pressure in the pipeline, which solves the problem that the oil in the pipeline cooperates to slow down the pressure of the oil on the pipe wall when the flow velocity is too large or too small, and avoids the oil in the zigzag pipeline during the flow process.
