Branched Orifice Channels for Faster Fluid Control Valve Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fluid control valves experience reduced responsiveness and flow rate due to inefficient fluid flow from vertical channels into horizontal channels, leading to suboptimal performance.
Innovation Solution
The fluid control valve design includes vertical channels that split into branch channels at the intersection with horizontal channels, allowing easier fluid flow into horizontal channels, with larger opening widths and a central channel that reduces pressure loss, and an annular recess to enhance flow rate and responsiveness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vertical channels are used without splitting, then the structure is simple, but the fluid flow into horizontal channels is inefficient and responsiveness deteriorates
Solution Approach 1:
The vertical channel is segmented into multiple branch channels that extend in different directions. This segmentation allows the fluid to be distributed to multiple horizontal channels more effectively, improving flow efficiency and responsiveness while maintaining a manageable structural complexity
Solution Approach 2:
The vertical channel transitions from a single-axis structure to a multi-branch three-dimensional structure. By adding spatial dimensions through branching, the channel system achieves better fluid distribution and responsiveness without excessive complexity
2Productivity
If only vertical channels are used, then the structure is simple, but the flow rate is limited
Solution Approach 1:
The design merges vertical channels with horizontal channels through strategic intersections and branching. This combination allows fluid to flow both vertically and horizontally, significantly increasing the overall flow rate while maintaining a unified channel structure rather than separate systems
Solution Approach 2:
The channel system is segmented into vertical and horizontal components that work together. The vertical channels feed into multiple horizontal channels through branching, creating a segmented yet integrated structure that achieves high flow rate without excessive complexity
3Productivity
If the vertical channel opening is small, then the structure is compact, but the fluid flow into horizontal channels is restricted
Solution Approach 1:
Instead of enlarging a single vertical channel, the design segments the flow path into multiple smaller branch channels. This segmentation allows the total fluid flow capacity to increase through parallel pathways while each individual channel remains compact, maintaining overall system compactness

AI summary
The present invention is intended to improve the responsiveness while increasing a flow rate, and is an orifice having a valve seat surface, the orifice includes: a vertical channel that opens to valve seat surface and a facing surface that faces the valve seat surface; and a horizontal channel that opens to an outer circumferential surface between the valve seat surface and the facing surface, and that intersects with the vertical channel. The vertical channel is split into a plurality of channel branches from an intersection with the horizontal channel, with a space therebetween, on a side of the facing surface.
