Line Connector Valve Seat Geometry for Low Flow Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing line connectors with valves exhibit high flow resistance due to their design, which is not present in connectors without valves.
Innovation Solution
The line connector features a valve with a non-circular flow aperture, such as star or flower-shaped, and an axially sliding valve guide integrated into the valve seat, eliminating the need for a separate valve holder, thereby reducing flow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a valve is arranged in the internal channel of the line connector, then fluid losses are prevented during detachment of the coupling arrangement, but flow resistance increases
Solution Approach 1:
The valve seat features a non-circular flow aperture (star-shaped, flower-shaped, or with enlarged peripheral area) that creates an asymmetric flow path. This asymmetric design enlarges the effective flow perimeter while maintaining the valve's sealing capability, thereby reducing flow resistance without compromising fluid loss prevention
2Stability of the object's composition
If a separate valve holder is used to mount the valve guide, then the valve structure is stable, but device complexity and flow resistance increase
Solution Approach 1:
The valve guide is integrated directly into the valve seat, merging two previously separate components (valve holder and valve seat) into a single unified structure. This integration eliminates the need for a separate valve holder, reducing device complexity and removing additional flow resistance sources while maintaining structural stability through the unified design

AI summary
A line connector for fluidic coupling with a complementary line connector comprises a connecting body. A valve is arranged in an internal channel, wherein the valve has a valve guide, an axially movable valve body, and a valve seat. The valve guide defines the movement direction of the valve body, wherein the line connector is designed such that the valve body rests in a fluid-tight manner on the valve seat in a locked state of the valve. It is provided that the valve seat has at least one flow aperture which in cross section deviates from a circular shape arranged concentrically with respect to the central axis M, and/or the valve guide is mounted to slide axially in a guide receptacle of the valve seat.
