Abstract

The invention relates to the technical field of pipeline water plugging, and discloses a water plugging device for petroleum pipeline maintenance, which comprises a standby oil delivery pipe, one end of the standby oil delivery pipe is provided with an end fixing ring, the outer side of the standby oil delivery pipe is slidably provided with a first sliding ring, and a first plugging elastic layer is arranged between the first sliding ring and the end fixing ring. A first cavity is formed between the first blocking elastic layer and the outer side wall body of the standby oil conveying pipe, the standby oil conveying pipe, the first blocking elastic layer, the sliding barrel, the first blocking elastic layer and the like are arranged, the first blocking elastic layer expands outwards and abuts against the wall body of the petroleum pipeline, and the first blocking elastic layer expands and abuts against the wall body of the petroleum pipeline. The outer side of the first plugging elastic layer abuts against the petroleum pipeline, petroleum in the pipeline can continue to flow through the standby petroleum conveying pipe, the petroleum conveying process of the original pipeline cannot be interrupted for a long time in the plugging process, and the influence of overhauling on the petroleum yield is reduced.

Description

technical field [0001] The invention relates to the technical field of pipeline water blocking, in particular to a water blocking device for oil pipeline maintenance. Background technique [0002] Oil pipelines (also known as pipelines and pipelines) are composed of oil pipes and their accessories, and are equipped with corresponding oil pump units according to the needs of the technological process. Task, when the pipeline needs maintenance, production usually needs to be suspended, and the maintenance process takes a long time, which will greatly affect the oil production. Therefore, the present invention needs to solve the problem of how to reduce the impact of the oil pipeline maintenance process on the transportation efficiency and production. [0003] CN207555068U discloses a water blocking device for oil pipeline maintenance, comprising an umbrella-shaped rubber plate, a support rod, a positioning block and a plurality of reinforcing rods arranged on the umbrella-shap...
