Problems solved by technology

However, this gap encourages water to pool between the end of the spigot and the end of the fitting, eventually causing dirt to settle in the gap between the end of the spigot and the bottom of the fitting
This stagnant water and / or these dirt deposits subsequently cause interruptions in the flow of water, which is not conducive to the proper flow of transported water

Embodiment Construction

[0022] figure 1 A pipe connection according to the invention, designated by reference numeral 2, is shown.

[0023] The coupling 2 comprises a spigot end 4 of a first pipe and a fitting end 6 of a second pipe. The socket end 4 extends along a central axis X-X and the fitting end 6 extends along a central axis Y-Y. The pipe joint 2 has an aligned configuration in which the two central axes X-X and Y-Y coincide and form the central axis of the pipe joint. In the following, the expressions "radial" and "axial" used in the context of an object refer to the central axis of the object. The pipe joint 2 also has an offset configuration with two central axes X-X and Y-Y forming a non-zero angle between them.

[0024] The socket end 4 includes a normal portion 4A and a beveled portion 4B. The normal part 4A has an outer spigot end surface 4C, which in the case to be described is cylindrical with a circular cross section. The beveled end portion 4B has a frusto-conical surface 4D. ...

Abstract

The invention relates to a pipe joint comprising a fitting end (6) connected to a shaft (8), and a spigot end (4) inserted into said fitting end ( 6), and includes the common part. The fitting end (6) comprises a base (10) provided with a fitting groove (12), a bottom groove (20) and a fitting bottom (22). The fitting end (6) comprises a protective element (26) which is located on the fitting bottom (22) and which protects the fitting bottom from contact with the socket end (4). Said protective element (26) comprises an axial bottom stop (27A) and a skirt (27B). Said skirt and said spigot end are adapted to position said spigot end (4) relative to said fitting end ( 6) An angular deviation of at least 2° occurs.

Description

technical field [0001] The invention relates to a pipe connection according to the preamble of claim 1 . Background technique [0002] Pipe fittings comprising a fitting end and an associated spigot end are known in the prior art. When the socket end is inserted into the fitting end, the socket end may collide with the bottom of the fitting and damage it. This is particularly problematic in the case of coatings provided on the inside and outside of the fitting end and the socket end, given that when the socket end hits the bottom of the fitting, it breaks the coating in the contact area, thereby promoting corrosion. [0003] In order to avoid such contact between the spigot end and the fitting bottom as much as possible, it is recommended not to insert the spigot end completely into the fitting end, thus leaving an axial gap between the spigot end and the fitting end. However, this gap promotes pooling of water between the end of the spigot and the end of the fitting, even...
