Embodiment Construction

[0012] As shown in the figure: a drainage pipe joint, including a pipe fitting 9 and a pipe material 1, is characterized in that: the end of the pipe material 1 is inserted into the end of the pipe fitting 9, and the end of the pipe material 1 is provided with an inward shrinkage Segment 8, the first expansion section 7 that expands outward is arranged on the position corresponding to the pipe shrinkage section 8 on the pipe fitting 9; the minimum outer diameter of the pipe shrink section 8 is slightly larger than the inner diameter of the pipe fitting 9, so The end of the pipe fitting 9 is provided with an inwardly shrinking pipe fitting shrinkage section 2, the smallest inner diameter of the pipe fitting shrinkage section 2 is larger than the outer diameter of the pipe material 1, and a space is formed at the overlapping portion of the pipe material 1 and the pipe fitting 9, and in the space Rubber sealing ring 3 is arranged inside.

[0013] At the end of the first expansion...

Abstract

The invention relates to a drain pipe joint, in particular to a drain pipe joint for a siphon principle, a vacuum principle and a gravity principle. According to the technical scheme of the invention, the drain pipe joint comprises a pipe fitting and a pipe stock and is characterized in that the end part of the pipe stock is inserted into the end part of the pipe fitting; the end part of the pipe stock is provided with a contracting section which contracts inwards; the pipe fitting is provided with a first expanding section which expands outwards and corresponds to the contracting section of the pipe stock; the minimum outside diameter of the pipe stock contracting section is slightly longer than the inside diameter of the pipe fitting; the end part of the pipe fitting is provided with a pipe fitting contracting section which contracts inwards, and the minimum inside diameter of the pipe fitting contracting section is longer than the outside diameter of the pipe fitting; space is formed at an overlaid part of the pipe stock and the pipe fittings, and the space is provided with a rubber sealing ring. The invention can enhance the sealing effect of the connection of drain pipes and simplify the installation process.

Description

technical field [0001] The invention relates to a drainage pipe joint, in particular to a drainage pipe joint applicable to the principles of siphon, vacuum and gravity. Background technique [0002] Drainage pipes such as domestic sewage are mostly installed on buildings. In the prior art, the connection between the drainpipes usually only uses a simple method to connect the two drainage pipes together; Stainless steel is welded on site, and plastic is melted on site. The common defect of these connection modes is: there is no sealing measure when connecting, therefore, in the process of use, leakage occurs at the junction of two drainage pipes very likely. Contents of the invention [0003] The purpose of the present invention is to design a drainpipe joint to improve the sealing effect of the drainpipe connection and simplify the installation process. [0004] According to the technical solution provided by the present invention, the drainage pipe joint includes a pip...
