Abstract

La présente invention concerne une vanne de régulation de fluide. La vanne de régulation comprend un corps de vanne et un ensemble noyau de vanne ; l'ensemble noyau de vanne comprend un premier noyau de vanne et un second noyau de vanne ; la vanne de régulation est pourvue d'une cavité de vanne ; le corps de vanne comporte des orifices ; le premier noyau de vanne et le second noyau de vanne sont situés dans la cavité de vanne ; et les orifices correspondant aux cavités de communication de l'ensemble noyau de vanne peuvent être ouverts ou fermés par rotation de l'ensemble noyau de vanne. La vanne de régulation comprend, en outre, une première partie de transmission et une seconde partie de transmission, la première partie de transmission et le premier noyau de vanne sont formés d'un seul tenant ou raccordés en transmission, et la seconde partie de transmission et le second noyau de vanne sont formés d'un seul tenant ou raccordés en transmission ; un arbre de vanne et le premier noyau de vanne sont raccordés de manière transmissive ; et lorsque le premier noyau de vanne se met en rotation, la première partie de transmission est en contact avec la seconde partie de transmission et entraîne la rotation du second noyau de vanne, de sorte que différents modes d'écoulement sont obtenus au moyen de deux noyaux de vanne. La structure d'assemblage entre les noyaux de vanne de la vanne de régulation est simple, l'impact est faible, et différentes combinaisons et modes de commutation de canal d'écoulement du premier noyau de vanne et du second noyau de vanne peuvent être obtenus.
