Modular Valve Assembly With Flow Sensing for Precise Flow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fluid distribution systems, such as those for pool operations, face challenges due to the limitations of current valve actuators in precisely setting flowrates and the increased complexity and cost associated with the large number of valves and actuators required, leading to space and maintenance issues.
Innovation Solution
A valve assembly design that includes a first housing with an open chamber, an inlet, and a fluid output chamber, featuring a valve member and an actuator for precise flow control, along with a flow rate sensor to monitor and adjust flow rates, allowing for modular and easily serviceable components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple valves and actuators are used to control flow rates in fluid distribution systems, then flow control capability is improved, but system complexity and installation cost increase
Solution Approach 1:
The valve body is divided into multiple independent flow paths (first flow path, second flow path, third flow path) that can be independently controlled by separate actuators. Each flow path can be controlled individually while sharing common valve body infrastructure, reducing overall system complexity while maintaining flow control capability.
Solution Approach 2:
A single valve assembly performs multiple flow control functions by incorporating multiple flow paths within one device. The valve can direct fluid flow to different destinations (first component, second component, or bypass) through a unified structure, eliminating the need for multiple separate valve assemblies.
2Measurement precision
If multiple valves and actuators are installed to provide precise flow control, then flow rate precision is improved, but installation time and labor cost increase
Solution Approach 1:
The valve body is divided into multiple independent flow paths (first flow path, second flow path, third flow path) that can be independently controlled by separate actuators. Each flow path can be controlled individually while sharing common valve body infrastructure, reducing overall system complexity while maintaining flow control capability.
Solution Approach 2:
Multiple flow control functions are merged into a single valve assembly. The first valve member controls flow to the first component, the second valve member controls flow to the second component, and the third valve member controls bypass flow, all within one integrated valve body that can be installed as a single unit.

AI summary
A valve assembly includes a first housing that defines an inlet and a fluid output chamber. A second housing is engaged to the first housing and a cover is engaged to the second housing. A valve member is positioned within the first housing. An actuator is positioned between the second housing and the cover and is attached to the valve member through an engagement located within the first housing. A flow rate sensor, as a component of the valve assembly, may be positioned downstream of the inlet and the fluid output chamber.
