Title:
WATERPROOF PIPE JOINT FOR FLEXIBLE PIPE
Document Type and Number:
Japanese Patent JPS57204388
Kind Code:
A
Abstract:
1. An impervious connector for ductile tubes, comprising for each tube (2) to be connected, a sleeve nut (1) threaded (7) on the outside to be attached on the tube (2) and to be screwed in a sleeve tube (10) bearing on the inside corresponding threadings (11), the sleeve tube (10) bearing on the inside, from its core (12) in the direction of each of its extremities (13), a convergent truncated tapered rotation surface (14) which emerges from the lower side wall (15) at a depth greater than the length of penetration of the sleeve nut (1) in the sleeve tube (10), characterised in that, the truncated tapered rotation surface (14) ends, on the core side (12) of the sleeve tube (10), in a cylindrical rotation surface, arranging thus a free space (16) in which, after assembly by screwing, the extremity of the tube (2), deformed, comes to lodge itself and compress itself and in that, the interior diameter of the sleeve nut (1) is greater than the exterior diameter of the cylindrical rotation surface ending the truncated tapered rotation surface (14).
