A water well recharge throttle valve ( ) is configured as a hydraulic actuated flow control device ( ) 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.

A water well recharge throttle valve is configured as a hydraulically actuated flow control device 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 eliminate the entrainment of air which may cause air fouling, bio-fouling, and 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. In each arrangement, the inner member contains fixed flow control openings in which an outer, upwardly based flow regulating tubular member is axially moved by a double acting hydraulic actuator to adjust flow through the flow control openings. The inner member has a wall with two passages therein for directing hydraulic fluid to opposite sides of a flow barrier thereon which separates a main chamber in the double acting hydraulic actuator into two sub-chambers.

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. Wherein the VoSmart 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, 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 the drop pipe, with a blind flange connected to the bottom end of the valve, a dedicated recharge well application. The inner member contains fixed flow control openings which an outer upwardly based flow regulating tubular member is axially moved with double acting hydraulic actuator to adjust the flow through the flow control openings. The axial position of the valve is controlled by a double acting hydraulic actuator built into the unit and completed through small stainless steel tubes to a hydraulic flow control valve and a hydraulic pump.

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. The axial position of the valve piston is controlled by a double acting hydraulic actuator completed through small stainless steel tubes to a hydraulic flow control valve and a hydraulic pump.

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.
