Abstract

Selon l'invention, des raccords de conduite pour le raccordement de conduites comprennent une enveloppe creuse (1) avec un filetage extérieur (2) créé d'un côté pour le vissage sur un filetage intérieur (10) d'un écrou (3) et avec un alésage (4) pour une douille creuse, une bande (5) de diamètre extérieur supérieur située dans l'alésage (4) de l'enveloppe (1), et une bande (6) avec un diamètre extérieur inférieur avec des stries (7) pour le tuyau raccordé. La bague fendue du dispositif de serrage (9) comprend un échelon sur la surface cylindrique extérieure et la surface cylindrique intérieure pour l'installation sur le tuyau, de façon concentrique à la bande (6) avec les stries extérieures (7). L'écrou (3) comprend une section conique intérieure (11) permettant d'agir sur la surface extérieure de la bague fendue (9). L'enveloppe (1) comprend un canal conique (18) s'élargissant entre l'alésage (4) et le trou avec le filetage (13) pour le raccord à la pompe. L'invention permet d'éviter le changement brutal de la section transversale d'écoulement dans l'enveloppe tout en offrant une augmentation de la résistance et de la fiabilité de l'enveloppe ; elle simplifie les procédures de construction et d'assemblage, et réduit les qualifications nécessaires pour les installateurs.
