Abstract

Valve dans laquelle les pertes hydrauliques au niveau de l'entrée de la valve et à l'interieur de cette dernière ont un effet négligeable sur la variation de l'écoulement, produite par la valve. Elle comprend un corps 12 ayant un alésage intérieur 14, des orifices d'entrée 18 et de sortie 22 ménagés dans ce corps et un tiroir 16 comportant des surfaces évidées 19 sur la circonférence qui coopèrent avec les parois intérieures du corps pour définir une voie d'écoulement limitée axialement entre les orifices d'entrée et de sortie, le tiroir comportant une portée 24 permettant de modifier la surface de sortie de la voie d'écoulement pour régler de ce fait l'écoulement du fluide dans la valve et un tube 26 traversant le corps et dont une extrémité communique avec la voie d'écoulement à proximité de la sortie, tandis que son autre extrémité débouche à l'extérieur du corps, ce qui permet de mesurer à l'intérieur de la valve la pression amont à 1a sortie de la valve. Application au réglage du débit d'un fluide.
