Abstract
An application for a flow control system includes a tapered plunger situated within an conduit. The conduit is open to a downstream drainage system. The tapered plunger is buoyant, assisted by one or more floats attached such that, when the water level around the flow control system increases to a predetermined level above a top rim of the conduit, the tapered plunger lifts due to the buoyancy. In such, the flow rate is maintained substantially constant. At the emergency level, alternate drain systems provide increased drainage to reduce the potential of flooding.
Claims19
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 open and leads to a drainage system;
- a tapered plunger, the tapered plunger fitting in place within the stationary riser hollow core defining a gap area between an outer surface of the tapered 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 tapered plunger, the at least one float providing buoyancy to the tapered 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 fluid communication with a liquid contained in the detention pond;
- a stationary riser, 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 top end of the stationary riser held within an aperture in a lid covering the holding box, liquid flowing through the stationary riser hollow core exiting the holding box through a drainage system;
- a tapered plunger, the tapered 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 tapered plunger;
- and
- at least one float interfaced to the tapered plunger, the at least one float providing buoyancy to the tapered plunger;
- whereas liquid from the detention pond flows over the rim, through the gap area, through the stationary riser hollow core and into the drainage system.
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, a shelf, and at least one opening located above the shelf and in fluid communication with a liquid contained in the detention pond;
- a stationary riser, 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 top end of the stationary riser held within an aperture in the shelf, liquid flowing through the stationary riser hollow core exits the holding box through a drainage system;
- a tapered plunger, the tapered 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 tapered plunger;
- and
- at least one float interfaced to the tapered plunger, the at least one float providing buoyancy to the tapered plunger;
- whereas liquid from the detention pond flows over the rim, through the gap area, through the stationary riser hollow core and into the drainage system.
