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.

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.

In order to prevent cascading of water flowing through a recharge pipe used for recharging an underground aquifer and to thereby minimize or eliminate introduction of air into aquifers, a valve is provided at the lower end of the recharge pipe which controls the rate of flow of recharge water. This is accomplished by providing an array of elongated, vertically extending slots in a section of the recharge pipe proximate the lower end of the recharge pipe, which slots are progressively opened by an overlying valve sleeve. In order to prevent recharge water from spraying laterally from the recharge pipe when the recharge valve is open, a throttle skirt extends laterally from the valve sleeve in spaced relation to the pipe so as to deflect the recharge water downwardly and directly toward the aquifer. This prevents the recharge well from being blocked by debris from the wall of the recharge well.
