Abstract

Un raccord (20) sert à raccorder des radiateurs (12, 13, 14, 15) faisant partie d'un circuit de chauffage d'une installation de chauffage d'un bâtiment à leur chaudière d'eau chaude. Les radiateurs sont montés entre le raccord au conduit d'alimentation et le raccord au conduit de retour de la chaudière et sont à leur tour pourvus chacun d'un raccord au conduit d'alimentation et d'un raccord au conduit de retour, par l'intermédiaire desquels l'eau chaude à la température d'alimentation est introduite dans les radiateurs ou ramenée à la chaudière. Un régulateur du débit (74) constitué par une vanne à 4/3 voies peut être commuté d'une première position d'écoulement (I) à une deuxième position d'écoulement (II) complémentaire de la première, en passant par une position d'obturation (0). Dans la première position d'écoulement (I), un manchon de raccordement (34 ou 36) du raccord (20) fixé au raccord (16) du conduit d'alimentation du radiateur (12, 13, 14, 15) est reliée à un manchon (42, 44) du raccord d'alimentation du raccord (20), alors qu'un manchon de raccordement (36, 34) du raccord (20) fixé au raccord (17) du conduit de retour du radiateur est relié à un manchon (43, 46; 82) de raccord au conduit de retour. La vanne à 4/3 voies (74) est conçue comme une vanne proportionnelle.
