Abstract

Skjøtekobling for rørledninger, f.eks. for skjøting av to rørender (10, 11) ved kaldt- eller varmtvanns- ledninger innen en bygning. Koblingen omfatter en skruehylse (13) som er dimensjonert for å romme rørendene (10, 11) og som ved hver av endene er forsynt med utvendige gjenger (12) og en mutterhylse (15) med tilsvarende innvendige gjenger (14). Skrue- og mutterhylsene (13, 15) er forsynt med overflater som samvirker med klamringer (17) som ved tiltrek- ning av mutterhylsene (15) deformeres rundt rør- endene og fikserer disse inne i mutterhylsene (15). Med formål å forenkle dannelsen av en tett skjøt er skruehylsen (13) forsynt med et innvendig anslag (18) for rørendene (10, 11). Dette anslag er plassert i en avstand fra den ene ende av skruehylsen som minst tilsvarer rørendens normale innstikksdybde, for dan- nelse av en skjøt med fullgod tetning. Avstanden mellom nevnte anslag (18) og den andre skruehylse- ende tilsvarer hovedsakelig dobbel normal innstikks- dybde.Connection for pipelines, e.g. for connecting two pipe ends (10, 11) by cold or hot water lines within a building. The coupling comprises a screw sleeve (13) dimensioned to accommodate the pipe ends (10, 11) and provided at each end with outer threads (12) and a nut sleeve (15) with corresponding internal threads (14). The screw and nut sleeves (13, 15) are provided with surfaces which cooperate with clamping rings (17) which, by tightening the nut sleeves (15), deform around the pipe ends and fix these inside the nut sleeves (15). For the purpose of simplifying the formation of a tight joint, the screw sleeve (13) is provided with an inner stop (18) for the pipe ends (10, 11). This stop is located at a distance from one end of the screw sleeve, which at least corresponds to the normal insertion depth of the pipe end, to form a joint with a full seal. The distance between said abutment (18) and the other screw sleeve end corresponds mainly to double normal insertion depth.
