Pipeline flange joint device for petroleum refining

Abstract

The invention discloses a pipeline flange joint device for petroleum refining, which comprises a sealing adjusting device, a connecting disc, a positioning hole, a rubber sealing ring and a flange plate, wherein the sealing adjusting device is electrically welded on the right side of the connecting disc and is vertical to each other, the four positioning holes are embedded in the four corners of the surface of the connecting disc and are connected to each other, the rubber sealing ring is arranged at the inner side of the positioning hole and is adhesively connected with the surface of the connecting disc, the flange plate is arranged behind the rubber sealing ring and is welded with the connecting disc. The pipeline flange joint device for petroleum refining adopts a closed adjusting device provided, seals the two ends of the pipeline together when there is no petroleum transmission is carried out, temporarily closes the two ends of the pipeline when petroleum is transferred by petroleum transmission device while staffs operating the device, so that the two ends of the pipeline are closed and separated, thereby the refined petroleum cannot be transferred temporarily, and the lossof petroleum leakage and other accidents could be reduced.

Description

technical field [0001] The invention relates to a pipe flange butt joint device for oil refining, which belongs to the field of oil pipelines and pipe joints. Background technique [0002] Oil Extraction: Oil is extracted from oil shale. Oil shale, also known as kerogen shale, is converted from sapropelic mud deposited in shallow seas and lakes. In addition to ancient aquatic plants, spores and pollen, its original material also has some animal matter. The current technical public equipment only has a simple fixed connection function. When loosening occurs, the pipes at both ends cannot be closed, and the flow at both ends cannot be controlled. , will make the phenomenon of oil leakage and oil leakage continue, resulting in huge losses. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the object of the present invention is to provide a pipe flange butt joint device for petroleum refining, so as to solve the problem that the common equipment...
