Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid flow regulation valves, such as butterfly and axial flap valves, face challenges in achieving optimal sealing and rapid variation of fluid passage sections while maintaining high flow rates and pressure, with complex leak management and slow fluid passage section variation.
Innovation Solution
A conical-shaped valve with a movable conical flap and fixed support, featuring fluid passage openings and a seal for axial displacement, allowing for contactless actuation and spontaneous movement to regulate fluid flow, ensuring complete sealing and linear fluid circulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a butterfly valve with a sealing element is used to control fluid flow, then sealing performance is improved, but the fluid passage cross-section is disrupted and the response speed is slowed
Solution Approach 1:
Instead of using a traditional butterfly valve where the sealing element rotates perpendicular to the flow axis, this invention inverts the approach by using a conical sealing element that rotates around an axis aligned with the fluid flow direction. This allows the sealing surface to remain parallel to the flow during rotation, maintaining both sealing performance and fluid passage efficiency.
Solution Approach 2:
The sealing element is designed with a conical shape rather than a flat butterfly shape. The conical geometry allows for optimized fluid flow patterns while maintaining effective sealing contact with the valve seat, eliminating the crescent-shaped disruption caused by traditional butterfly valves.
2Quantity of substance
If a butterfly valve is used to allow high flow rates, then fluid passage is improved, but the movement speed is slow and sealing complexity increases
Solution Approach 1:
The conical sealing element is designed to rotate dynamically around an axis aligned with the fluid flow, allowing rapid opening and closing movements. The conical geometry and axial rotation mechanism enable faster response times compared to traditional butterfly valves while maintaining high flow rates when open.
3Productivity
If an axial flap valve is used to align the rotation axis with fluid flow, then fluid circulation is improved, but actuation difficulty increases
Solution Approach 1:
The conical shape of the sealing element provides natural aerodynamic/hydrodynamic characteristics that facilitate rotation around the axial flow direction. The conical geometry reduces resistance to rotation and improves actuation ease compared to flat axial flaps, while maintaining aligned fluid circulation.

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 conical valve provides equivalent fluid passage sections to butterfly valves with improved sealing and rapid flow regulation, maintaining linear fluid circulation and reducing friction and wear, while eliminating the need for direct contact actuation, thus enhancing operational efficiency and reliability.
