Embodiment Construction

[0017] First refer to figure 1 , shows a joint according to the invention. The joint comprises a first part 1 in the form of a plug and a second part 2 in the form of a socket, into which the plug part enters and thus forms an annular aperture 3 at the interface between the plug part and the socket part. This annular aperture is along the axial direction of the plug part and the socket part, which are delimited by an inner limit 4 on the inside and an outer limit 5 on the outside. Moreover, from the outer surface of the socket part to the aperture 3, there are feed through holes 6 for injecting glue into the aperture, and feed through holes 7 for ventilation and glue leakage when filling the aperture with glue. It is evident from the figure that the feed through hole 7 for ventilation and glue leakage is arranged closer to the outside than the feed through hole 6 for injecting glue. Wherein the outer side refers to a place closer to the opening where the plug part enters th...

Abstract

Coupling, comprising a first part (1) in the form of a male part and a second part (2) in the form of a female part, the male part can be brought into the female part and thereby form a ring shaped void (3) between the facing surfaces of male and female parts, which ring shaped void in the axial direction of the parts are delimited with an inner restriction (4) at an inner side and an outer restriction (5) at an outer side, and a feed-through (6) is arranged from the outer surface of the female part to the void (3), for injection of glue into the void, and a feed-through (7) is arranged from the void to the outer surface of the female part, for venting and leakage of glue when filling the void with glue, distinguished in that the feed-through (7) for venting and leakage of glue is arranged closer to the outer side of the void than the feed-through (6) for injection of glue.

Description

technical field [0001] The invention relates to a joint between a first part in the form of a plug and a second part in the form of a socket, said parts being permanently connected together by means of glue. These parts are preferably pipes or fittings. Background technique [0002] The glue is particularly suitable for joining parts of non-weldable materials, such as reinforced thermoset polymer materials, such as fiber-reinforced polymer (FRP) pipes or pipe fittings. [0003] A glued joint and connection method is described in published patent NO311272. More particularly, the joint is formed by gluing together two objects, at least one of which includes a pipe-forming connection capable of being screwed to or placed on the other object, the distinguishing feature being that between the object and the first A demarcation aperture is formed between pipe-forming connection parts of an object, and a first aperture extends from an outer surface of the pipe-forming connection ...
