Fluid Control Valve Bypass Flow Path for Lower Pressure Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The occurrence of pressure loss due to the reduction in flow path area when fluid flows from a larger area to a smaller area in conventional fluid control valves leads to deterioration in water permeability.
Innovation Solution
A fluid control valve design that includes a bypass flow path portion guiding fluid to bypass facing flow path portions, maintaining a continuous flow direction in the circumferential direction, reducing pressure loss by avoiding radial flow direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If fluid flows from a larger area to a smaller area in conventional fluid control valves, then the valve structure is compact and functional, but pressure loss occurs due to reduction in flow path area
Solution Approach 1:
The patent introduces a bypass flow path that extends in the circumferential direction, perpendicular to the axial flow direction. This dimensional change allows fluid to bypass the restricted axial flow path through a longer but wider path, maintaining flow area and reducing pressure loss while keeping the valve compact
2Ease of operation
If fluid flows radially from a larger area to a smaller area, then the valve achieves flow control function, but water permeability deteriorates due to flow path area reduction
Solution Approach 1:
The patent divides the flow path into multiple segments: a facing flow path portion for direct axial flow and a bypass flow path portion for circumferential flow. This segmentation allows fluid to choose different paths, maintaining overall flow control functionality while improving water permeability through the bypass path that avoids area reduction
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design reduces pressure loss and enhances fluid permeability by guiding fluid through a bypass flow path that maintains a continuous flow direction, thereby improving the efficiency of fluid circulation systems.
Implementation Method 1
a bypass flow path portion configured to guide fluid flowing in from the end-portion fluid inlet to the end-portion fluid outlet while bypassing a portion facing the plurality of opening portions in the valve outer wall portion

AI summary
A housing has two or more opening portions in the axial-center direction and in the circumferential direction. A fluid inlet includes an end-portion fluid inlet on one side or the other side in the circumferential direction. A fluid outlet includes an end-portion fluid outlet on one side or the other side in the circumferential direction. The flow path portions include a facing flow path portion that guides fluid flowing from the fluid inlet directly to the fluid outlet, and a bypass flow path portion that guides fluid from the end-portion fluid inlet to the end-portion fluid outlet while bypassing the valve outer wall portion. The bypass flow path portion is continuously formed in the circumferential direction with respect to the facing flow path portion.
