Abstract: A water well recharge throttle valve (1) is configured as a hydraulic actuated flow control device (5) that permits calibrated throttling of water used in Artificial Storage and Recovery (ASR), Salt Water Barrier, Dedicated Recharge and Injection Wells to prevent the free cascading of water and thereby eliminating the entrainment of air which may cause air fouling, bio-fouling, calcite formation with a resultant reduction in permeability of the aquifer.

The valve includes a fixed tubular member which is selectively mounted in one of three ways: (1) to the lower end of the pump column, below the pump with a check valve/strainer mounted below the unit and including a co-generation/recharge feature; (2) to the lower end of the pump column, and above the check valve and submersible pump; and (3) to the lower end of a drop pipe, with a blind flange connected to the bottom end of the valve, a dedicated recharge well application.

Abstract: The VoSmart (a Variable Orifice/ Selective Monitored Artificial Recharge Throttle) Valve is a disclosed and the preferred embodiment of a hydraulically actuated flow control device that permits the calibrated throttling of water used in Artificial Storage and Recovery (ASR), Salt Water Barrier, Dedicated Recharge and Injection Wells to prevent the free cascading of water and thereby eliminate the entrainment of air which may cause air fouling, bio-fouling, and calcite formation with the resultant reduction in permeability of the aquifer.

Abstract: The Variable Orifice Valve is disclosed and the preferred embodiment of a hydraulically acruated.sub.-- flow control device that permits the calibrated throttling of water used in a Artificial Storage and Recovery (ASR), Dedicated Recharge, Injection, Salt Water Barrier Wells used in aquifer storage.sub.-- or utilized in other industries where fluid flow control is required and desired. Aquifer storage of treated drinking water is the placement of water in aquifers during periods of surplus water for recovery of the water during peak demands or forming a barrier to protect a fresh water aquifer. This invention, when installed in a recharge well, is a device installed below the static water level and at or near the bottom of the drop pipe and near the top of the well screen. The size of the orifice and the liquid flow is varied by the axial positioning or adjustment of a double acting hydraulic actuator connected to valve piston.

Abstract: The Variable Orifice Valve is disclosed and the preferred embodiment of a hydraulically actuated device that permits the calibrated throttling of water used in an Aquifer Storage and Recovery (ASR). ASR is the storage of treated drinking water in an aquifer during periods of surplus water for recovery during peak demands. This device is installed below the static water level and at or near the bottom of the column pipe in the recharge well. The size of the orifice and the flow of water is varied by the axial adjustment of a hydraulic piston. The axial position of the piston is controlled by a hydraulic actuator competed through steel tubing to a hydraulic pump at the well head. The flow is monitored by using a flow meter and pressure gage in the hydraulic fluid passageway. The desired flow is set by adjusting the Variable Orifice Valve hydraulically while monitoring the flow. The operator may adjust the flow of water to any increment within the range of the valve.
