Bend-position shunting and mutual-weakening type self-protective petroleum pipeline

Abstract

The invention discloses a bend-position shunting and mutual-weakening type self-protective petroleum pipeline, and belongs to the field of petroleum pipelines. The bend-position shunting and mutual-weakening type self-protective petroleum pipeline is characterized in that petroleum which flows into an elbow pipe is divided into inner-layered fluid and outer-layered fluid with unequal flow througha shunting deformation sleeve; the outer-layered small-flow petroleum acts upon an inner bending pipe and an outer bending pipe, and the inter-layered large-flow petroleum acts upon the shunting deformation sleeve, and thus, on one hand, impact force of the petroleum against the outer bending pipe and the inner bending pipe can be greatly weakened, and the impact of the petroleum against the elbowpipe is primarily weakened; and meanwhile, under impact flowing of the petroleum, a turning force ball is rotated on the inner bending pipe, so that the outer-layered petroleum realizes mutual convection and collision, and the impact of the petroleum against the elbow pipe can be weakened secondarily; and on the other hand, the shunting deformation sleeve is impacted through the inner-layered petroleum, so that expansion deformation on an elastic sack toward the outside occurs, and stacking on the outer-layered petroleum occurs, and thus, the outer-layered petroleum sprays inwards through overflow holes, and convection between the outer-layered petroleum and the inner-layered petroleum is formed, and impact force of the inner-layered petroleum is weakened, and therefore, tertiary protection on the elbow pipe is realized.

Description

technical field

[0001] The invention relates to the field of oil pipelines, more specifically, to a self-protecting oil pipeline of the bending point diversion and mutual elimination type. Background technique

[0002] With the rapid development of today's society, energy is an indispensable resource. Petroleum is a kind of naturally stored energy. The exploitation of petroleum requires drilling to extract oil, petroleum smelting, and then transporting it to various sites for use. Oil transportation is carried out through the oil pipeline system, which is mainly composed of oil pipelines, oil stations and other auxiliary related equipment. It is one of the main equipment in the oil storage and transportation industry and the most important transportation equipment for crude oil and petroleum products. Compared with railway and road oil transportation, pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high saf...
