Embodiment Construction

[0026] specific implementation plan

[0027] The interlock joint shown in Figure 1 is of the type described in French patent FR-A-2505014 in the name of the present applicant, differing in the construction of the locking ring. The interlocking joint comprises: a connection end 1 belonging to the first pipe 2 of the pipeline, a coupling sleeve 3 belonging to the second pipe 4 of the pipeline, a radially compressed seal 5 which at least partially surrounds the connection end and is in the connection Welding rib 6 (or, as a variant, a cast-in stop projection) in the transverse plane of the end, and locking ring 7 . Both pipes 2 and 4 are made of gray or nodular cast iron, the locking ring 7 is metallic, for example also gray or nodular cast iron, and the seal 5 is an elastic part. The two tubes are shown fully aligned along a common axis X-X.

[0028] From the back to the front, that is, starting from the entrance, the inside of the adapter sleeve includes in turn: the entrance...

Abstract

An interlocking joint for piping components, the joint comprising a metallic split lock ring having a set of grooves (19) on at least one face (16) of the lock ring (19) for retaining the lock ring (7) when the joint is installed The required gathering, staggering of ends, and expansion occurs. Can be used for interlocking connections between cast iron pipes.

Description

technical field [0001] This invention relates to interlocking joints between piping components, particularly pipes, and metallic split locking rings usable in such joints. [0002] Said pipeline elements are not only pipes, but also accessories of pipelines, such as switching elements. In what follows, we assume that pipes are involved. Background technique [0003] The interlock joint between the tubes is a sealed assembly that resists the separation forces created by the line pressure. A typical interlock joint usually includes: a coupling sleeve on the first pipe; a connecting end on the second pipe, which is inserted into the coupling sleeve through an annular seal; a protrusion connected to the coupling end; A lock ring of the opening is provided, the lock ring is located just behind the protrusion; and a rear bearing surface of the lock ring is connected with the adapter sleeve. [0004] The rear bearing surface of the split ring can rest on a flange which engages i...
