摘要：
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.
