Description

Pipeline connecting structure

Technical Field

The invention belongs to the technical field of pipe fittings, and particularly relates to a pipeline connecting structure.

Background

In the existing pipeline butt joint technology, flange connection is a common pipeline connection mode. The required connecting bolt nut quantity of current flange joint is more, wastes time and energy, and simultaneously, at some small pipe diameter pipelines, in using the flange to carry out the connection process, the cross-sectional area that the method was even in the outside is great relatively, and is inconvenient during the installation.

Disclosure of Invention

In view of the above problems in the prior art, an object of the present invention is to provide a pipe connection structure, which can avoid connecting pipes by using a flange connection method, and has relatively good sealing performance.

In order to achieve the above object, the present invention provides a technical solution as follows:

a pipeline connecting structure comprises a first pipeline and a second pipeline, wherein a first positioning ring is arranged at one end, close to the second pipeline, of the first pipeline, a second positioning ring is arranged at one end, close to the first pipeline, of the second pipeline, and a connecting assembly for connecting and pressing the first positioning ring and the second positioning ring is arranged on the outer sides of the first positioning ring and the second positioning ring; and a sealing element is arranged between the first positioning ring and the second positioning ring.

Preferably, the connection assembly comprises a first sleeve comprising a first abutment end and a first threaded section and a second sleeve comprising a second abutment end and a second threaded section; the first abutting end abuts against one side, away from the second positioning ring, of the first positioning ring, and the second abutting end abuts against one side, away from the first positioning ring, of the second positioning ring; the first thread section and the second thread section are respectively sleeved on the outer sides of the first positioning ring and the second positioning ring and are in threaded connection with each other.

Preferably, the sealing element comprises a sealing ring annularly arranged at the outer side of the first positioning ring and the outer side of the second positioning ring, a first sealing gasket arranged at the inner side of the sealing ring and positioned between the first positioning ring and the second positioning ring, and a second sealing gasket positioned at the side, far away from each other, of the first positioning ring and the second positioning ring; and the first sealing gasket is provided with an annular convex rib.

The pipeline connecting structure provided by the invention can avoid the adoption of a flange connection mode for connecting pipelines, and has relatively good sealing property.
