Pressure-Regulating Valve Cover Structure for Higher Fluid Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure-regulating valves face limitations in fluid flow due to restricted flow paths caused by gaps between components, which hinder efficient release of fluid when internal pressure exceeds a threshold.
Innovation Solution
A pressure-regulating valve design featuring a cover part with a circumferential edge, a seal part, and an elastic member that urges the cover part toward the enclosure, supported by a base part, allowing for increased fluid flow by minimizing obstruction and maximizing the gap for fluid release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the pressure-regulating valve uses gaps between components (base part and cover part, or valve and enclosure) for fluid release, then the structure is simple, but the fluid flow rate is restricted
Solution Approach 1:
The valve body is divided into a stationary base part and a movable cover part that can independently move relative to each other. This segmentation allows the cover part to be displaced by internal pressure, creating a larger fluid passage without requiring complex multi-component assemblies.
Solution Approach 2:
The cover part is designed to move dynamically in response to internal pressure changes. When internal pressure exceeds external pressure, the cover part displaces toward the external side, automatically enlarging the fluid passage area. This dynamic adjustment eliminates the need for fixed, restricted gaps while maintaining structural simplicity.
2Productivity
If the cover part is positioned close to the opening to maximize flow area, then fluid flow rate increases, but sealing becomes more difficult
Solution Approach 1:
A seal part is introduced as an intermediary element between the cover part and the enclosure. This seal part ensures reliable sealing when the cover part is in its retracted position (maximizing flow area) while allowing the cover part to move freely for pressure equalization. The seal part mediates between the conflicting requirements of open flow and sealed closure.
Solution Approach 2:
The seal part is positioned locally at the interface between the cover part and enclosure, providing sealing function only where needed. This localized sealing approach allows the cover part to be positioned close to the opening for maximum flow area while maintaining reliable sealing through the dedicated seal part.

AI summary
A pressure-regulating valve for escaping a fluid inside an enclosure from an opening of the enclosure when internal pressure of the fluid rises. The pressure-regulating valve includes a cover part that includes a circumferential edge surrounding the opening in a plan view and that covers the opening, a seal part positioned between the circumferential edge of the cover part and a surface of the enclosure, an elastic member configured to generate urging force urging the cover part toward the enclosure in a first direction, and a base part that is fixed to the enclosure and that supports the elastic member such that the elastic member expands and contracts in the first direction.
