A self-cleaning oil pipeline connection flange

Abstract

The invention relates to the field of petroleum flange manufacturing. Specifically, it is a self-cleaning petroleum pipeline connecting flange, which includes a flange mounting seat and a cleaning device. The cleaning device is connected to the flange mounting seat, and the cleaning device includes Inner support ring, two annular racks, connecting support frame, cleaning broom, positioning gear and double-head motor. The inner support ring is connected to the flange mounting seat through the connecting support frame; the two annular racks They are installed on the inner support ring and the flange mounting seat respectively; the positioning gear meshes with two annular racks; the motor spindles at both ends of the double-head motor spindle are connected to the positioning gears respectively; the cleaning broom Installed on the outside of the positioning gear through interference fit. The underwater connecting flange of an oil pipeline described in the present invention adopts a ring rack and gear transmission method to realize regular cleaning of the oil pipeline flange connection, which is beneficial to the use of the oil pipeline and improves production efficiency.

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
