Abstract
An application for a flow control system includes a movable plunger held within a stationary riser, the stationary riser being in fluid communication with a drainage system. The movable plunger is buoyant, assisted by one or more attached floats such that, when the liquid level around the flow control system increases to a pre-determined level, the movable plunger lifts due to the buoyancy, thereby maintaining the pre-determined distance between the surface level and a bottom surface of the movable plunger, keeping the flow rate at an approximately constant level independent of the water level.
Claims20
A flow control system for integration into a detention pond, the flow control system comprising:
- a stationary riser, the stationary riser having a stationary riser hollow core, an axis of the stationary riser hollow core being vertical, a top end of the stationary riser has a rim and the opposing end of the stationary riser is fluidly connected to a drainage system;
- a movable plunger, the movable plunger fitting in place within the stationary riser hollow core defining a gap area between an outer surface of the movable plunger and an inner surface of the stationary riser hollow core, whereas liquid from the detention pond flows over the rim, through the gap area, through the hollow core and into the drainage system;
- and
- at least one float interfaced to the movable plunger, the at least one float providing buoyancy to the movable plunger.
A flow control system for integration into a detention pond, the flow control system comprising:
- a holding box, the holding box installed in a bed of the detention pond, the holding box having an interior cavity and at least one opening in communication with liquid contained in the detention pond;
- a stationary riser positioned within the holding box, the stationary riser having a stationary riser hollow core, an axis of the stationary riser hollow core being substantially vertical, a top end of the stationary riser having a rim, the stationary riser hollow core fluidly connected to a drainage system;
- a movable plunger, the movable plunger fitting within the stationary riser hollow core to form a gap area between an inner surface of the stationary riser hollow core and an outer surface of the movable plunger;
- and
- at least one float interfaced to the movable plunger, the at least one float providing buoyancy to the movable plunger;
- whereas liquid from the detention pond flows over the rim and through the gap area and through the stationary riser hollow core and into the drainage system.
