Detailed Description

Example one

The embodiment is described based on the background of the closing stage of the pipeline connection construction, specifically, the water pipeline is generally horizontally arranged, the pipeline connecting piece is used for the final closing stage of the flange-connected pipeline, and in the construction engineering of the flange-connected pipeline, due to construction errors, the pipeline connecting piece can be used for performing quick connection construction at the final closing stage.

The pipeline connecting piece is a telescopic structure consisting of a core pipe 100, a sleeve pipe 200, a sliding pipe 300 and a locking nut 400, and the telescopic direction of the telescopic structure is axial.

The core tube 100, referring to fig. 1, in a horizontal arrangement, comprises, in order from left to right on the core tube: the pipeline flange comprises a flange plate I110, a ring-shaped chuck 120 and a sealing section 130, wherein bolt holes are formed in the flange plate I110, and the flange plate is used for being connected with a pipeline flange on one side. The ring chuck 120 is an annular projection at the middle section of the core tube, which is present to assist in securing the outer sleeve. The end far away from the flange plate I is provided with a sealing section 130 which is an outward convex annular body, the outer surface of the sealing section is provided with an annular sealing ring installation groove, and a sealing ring 140 is arranged in the installation groove. In order to further achieve the preferable effect, the number of the sealing rings is plural, for example, three are given in the nature of the example shown in fig. 1.
