Integrated Control Valve for Water Softener Regeneration Flow Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing valve systems for controlling liquid flow in water treatment processes are complex and require multiple valves and piping for functions like ion exchange resin regeneration and liquid treatment, leading to inefficiencies and increased complexity.
Innovation Solution
A control valve with a movable piston and annular flow passages that allows selective direction of liquid flow through multiple paths, integrating functions like ion exchange resin regeneration, water shutoff, and bypass, eliminating the need for separate valves and piping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate valves and piping are used to control liquid flow for different process steps, then each function (shutoff, bypass, regeneration) can be independently controlled, but the system complexity and number of components increases
Solution Approach 1:
The patent combines multiple valve functions (shutoff valve, bypass valve, and regeneration control) into a single integrated valve assembly. The piston element simultaneously controls flow paths to multiple ports, enabling shutoff, bypass, and regeneration operations through one coordinated mechanism rather than separate valves, thereby reducing system complexity while maintaining functional versatility
Solution Approach 2:
The single valve assembly is designed to perform multiple functions: it can shut off liquid flow to process equipment, provide bypass flow paths, and control regeneration of ion exchange resin. The piston's ability to position itself to connect different ports enables one component to replace multiple specialized valves, achieving multi-functionality without increasing overall system complexity
2Reliability
If separate valves are used for shutoff and bypass functions, then each function can be precisely controlled, but the number of components and piping required increases
Solution Approach 1:
The shutoff and bypass functions are merged into a single piston-controlled valve assembly. The piston's position determines whether liquid flows through the main process equipment or through the bypass path, with both functions controlled by the same mechanism. This eliminates the need for separate shutoff and bypass valves while maintaining precise flow control through the piston's selective port connection

AI summary
An exemplary liquid treatment system includes at least one control valve in operative connection with a liquid treatment tank. The liquid treatment tank includes treatment material therein that is operative to treat the liquid that passes therethrough. The liquid treatment material is periodically regenerated to restore treatment function. At least one valve controller is operative to control the flow of liquid through the liquid treatment tank and to deliver treated liquid to liquid use devices. A further tank is operative to produce a saturated liquid solution of regeneration material that is usable to regenerate the liquid treatment material in the liquid treatment tank. The further tank includes at least one pressure sensor and at least one temperature sensor. The at least one pressure sensor and at least one temperature sensor are in operative connection with the at least one valve controller to determine that adequate saturated regeneration material is produced and delivered to the liquid treatment tank.
