A self-cleaning oil pipeline connection flange

Abstract

The invention relates to the field of petroleum flange manufacturing, and specifically relates to a self-cleaning connection flange for a petroleum pipeline. The self-cleaning connection flange for the petroleum pipeline comprises a flange installation seat and a cleaning device, wherein the cleaning device is connected with the flange installation seat, the cleaning device comprises an inner support ring, two annular racks, a connection support frame, a cleaning besom, a location gear and a double-end motor, and the inner support ring is connected with the flange installation seat through the connection support frame; the two annular racks are installed on the inner support ring and the flange installation seat respectively; the location gear is engaged with the two annular racks; motor main shafts at the two ends of the main shaft of the double-end motor are connected with the location gear respectively; and the cleaning besom is installed at the outer side of the location gear in a manner of interference fit. The underwater connection flange for the petroleum pipeline, which is disclosed by the invention, adopts an annular rack-gear transmission manner to realize periodic cleaning for the junction of the flange of the petroleum pipeline, thus use of the petroleum pipeline is benefited, and the production efficiency is increased.

Description

technical field [0001] The invention relates to the field of oil flange manufacturing, in particular to a self-cleaning oil pipeline connection flange. Background technique [0002] Nowadays, with the continuous development of human civilization, the continuous innovation of industrial level, and the continuous improvement of oil extraction technology, the longest problem encountered in the process of oil extraction is the transmission problem encountered in the process of oil extraction. In the prior art, pipelines are usually used for oil extraction. It can be seen that the requirements for oil transmission pipelines are relatively high in the process of oil extraction, and the selection of connectors for oil transmission pipelines is also important during the transmission process. Pipeline connectors are usually connected by flanges. In the existing oil pipeline connection flanges, it is usually aimed at the connection between two pipelines, and oil pipelines usually form...

[0002] Nowadays, with the continuous development of human civilization, the continuous innovation of industrial level, and the continuous improvement of oil extraction technology, the longest problem encountered in the process of oil extraction is the transmission problem encountered in the process of oil extraction. In the prior art, pipelines are usually used for oil extraction. It can be seen that the requirements for oil transmission pipelines are relatively high in the process of oil extraction, and the selection of connectors for oil transmission pipelines is also important during the transmission process. Pipeline connectors are usually connected by flanges. In the existing oil pipeline connection flanges, it is usually aimed at the connection between two pipelines, and oil pipelines usually form oil at the flange connection during the oil transmission process. The accumulation of impurities, long-term accumulation can easily cause blockage of oil pipelines, resulting in technical problems in oil exploitation. In view of this, the present invention provides a self-cleaning oil pipeline connection flange, which adopts the transmission of ring rack and gear The method realizes the regular cleaning of the flange connection of the oil pipeline, which is beneficial to the use of the oil pipeline and improves the production efficiency
