US Patent 9719604 Check valve for a fluid flow regulation system

Embodiments include a flow regulating device. The flow regulating device may include a check valve. The check valve can have a first flange, a second flange and a ball seated against a seat defined by the first flange. The check valve is in a closed position when the ball is seated against the first flange. One or more stoppers may be positioned at a distance from the first flange. A fluid may flow through a first orifice and a second orifice defined in the first and second flanges respectively, when the first check valve is in an open position. The fluid lifts the ball from the first orifice, and pushes the ball towards the second orifice. The stoppers abut the ball when the first check valve is in a fully open position.
