CA 2662360
A flow control device includes a fitting having three portals. One of the portals is an entry portal for a liquid, one of the portals is an entry portal for a gas, and the other portal is an exit portal for either the liquid or the gas. A normally closed back flow prevention valve is located in fitting. The back flow prevention valve prevents back flow of liquid through the fitting. The fitting and the backflow prevention valve also minimize or eliminate the formation of air bubbles in the liquid.
La présente invention concerne un dispositif de commande de débit qui inclut un raccord comprenant trois portiques. Un des portiques est un portique d'entrée pour un liquide, un des portiques est un portique d'entrée pour un gaz, et l'autre portique est un portique de sortie soit pour le liquide ou le gaz. Une vanne anti-retour normalement fermée est située dans le raccord. La vanne anti-retour empêche le retour de liquide à travers le raccord. Le raccord et la vanne anti-retour minimisent également ou éliminent la formation de bulles d'air dans le liquide.
