Embodiment 1

[0034] like Figure 1-Figure 3 As shown, the present invention is a pipeline connection structure, comprising a pipe sleeve 1, a flaring member 2 and two pipes 3 to be connected, the outer diameters of the two pipes are consistent, and the connection of the two pipes is at on the same line. The sleeve 1 is provided with a connection hole 1-1 corresponding to the pipe material 3 and a stop edge 1-2 that is press-fitted with the end of the pipe material. An inclined surface 1-3 is provided inside the connection hole to form a narrow entrance and a wide rear part. The trumpet-shaped structure, the inclined surface is provided with a seal 4, the flared piece is pressed tightly into the connection end of the pipe, and the pipe with the built-in flared piece is inserted into the connection hole. The flaring piece is an annular trumpet-shaped flaring structure, and the side of the flaring piece is provided with a tooth-2-1. It should be noted that the flaring member can also be con...

Embodiment 2

[0039] like Figure 4 As shown, in this embodiment, the pipe sleeve 1 is arranged in the form of an elbow, and the two pipes are correspondingly connected with each other, and the two pipes are connected through the cooperation of the pipe sleeve 1 to form a joint structure perpendicular to each other.

Embodiment 3

[0041] like Figure 5 As shown, in this embodiment, the pipe sleeve 1 is set in the form of a three-way pipe, correspondingly connected to three pipes.

Abstract

The invention discloses a pipeline connection structure and application thereof. The pipeline connection structure is characterized by comprising a pipe sleeve, flaring pieces and at least two to-be-connected pipes; the pipe sleeve is provided with connection holes corresponding to the pipes, and stop flanges matched with the ends of the pipes in an abutting mode; the connection holes are internally provided with inclined faces, thus, a horn-shaped structure which is narrow in inlet and wide in rear portion is formed, and the inclined faces are provided with sealing pieces; the flaring piecesare tightly pressed in the connection ends of the pipes, and the pipes internally provided with the flaring pieces are inserted into the connection holes. The pipeline connection structure is simple,convenient to assemble and good in stability.

Description

technical field [0001] The invention relates to the technical field of pipeline connection, in particular to a pipeline connection structure and its application. Background technique [0002] At present, the connection and installation of pipelines is generally to fix one pipe to the branch opening of another pipe by means of hot melting, electric melting, socket insertion, etc., which has a simple structure and is easy to install. However, for pipelines hidden underground, due to the complex underground conditions, it is difficult to install the pipes connected by hot-melt, electric fusion, and socket welding methods, and the connected pipes are prone to detachment due to the influence of external forces. have a great impact on users. Contents of the invention [0003] The purpose of the present invention is to provide a pipe connection structure with simple manufacturing process, convenient assembly and disassembly, and good stability in order to solve the deficiencies ...
