A pipeline connection structure and connection method thereof

Abstract

The invention relates to a pipeline connecting structure and a connecting method thereof, and belongs to the technical field of pipeline butt joint. The connecting structure comprises connecting pipesand two connecting mechanisms, wherein pipelines are connected with the connecting pipes through the connecting mechanisms, and the connecting mechanisms comprises connecting inner cylinders, first sealing rings, connecting outer cylinders and clamping pieces; the connecting inner cylinders comprises inner cylinder bodies and a plurality of connecting arc plates, the outer surfaces of the connecting arc plates are provided with conical surfaces, and the outer diameters of the connecting arc plates are gradually reduced in the direction away from the inner cylinder bodies; the connecting outercylinders comprises outer cylinder bodies, connecting sleeves and fastening ring plates, wherein the outer cylinder bodies and the connecting sleeves are sleeved on the outer peripheral surfaces of the inner cylinder bodies and are in threaded connection with the inner cylinder bodies, and the fastening ring plates abut against the outer surfaces of the connecting arc plates, the clamping piecescomprises first circular ring plates, circular ring bottom plates and second circular ring plates, clamping circular ring plates are fixedly arranged on the second circular ring plates, and clamping grooves are formed in the first circular ring plates. According to the pipeline connecting structure, the connecting pipes can be recycled, the alignment of the connecting pipes and the pipelines is facilitated, and the butt joint of the two pipelines is more convenient and more stable.

Description

technical field [0001] The invention relates to the technical field of pipeline butt jointing, in particular to a pipeline connection structure and a connection method thereof. Background technique [0002] In the construction process, it is unavoidable to butt the two pipelines in order to realize the connection of the two pipelines. In the prior art, a connecting pipe is generally arranged between the two pipelines, and one end of the connecting pipe is connected to one of the pipes. Welding, and then weld the other end of the connecting pipe with another pipe to realize the butt joint of the two pipes. In this way, although the butt joint of the two pipes is realized, not only the connecting pipe cannot be recycled, but also the connecting pipe cannot be recycled. When the pipe and the pipe are welded, an external support is needed, so it is not convenient for the alignment of the connecting pipe and the pipe, that is, the butt joint of the two pipes is cumbersome.
