Multi-Port Valve Core Layout for Lower Water Flow Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-port valves experience high flow resistance due to the small circumferential interval between water connection ports, causing inefficiencies in fluid transport.
Innovation Solution
A multi-port valve design featuring a valve core with a first channel that penetrates the valve core, allowing for increased axial interval between interfaces and reducing flow resistance. The first channel can be straight or inclined, optimizing flow efficiency.

Engineering Contradiction Analysis
1Volume of moving object
If water connection ports are disposed close to each other on the valve body, then the valve structure is more compact, but the flow resistance increases due to sharp curves in the fluid path
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement of water connection ports to a three-dimensional spatial configuration. The first and second water connection ports are positioned on opposite sides of the valve core in the axial direction, with the first channel penetrating through the valve core to connect them. This dimensional change allows the ports to be spatially separated while maintaining compact overall valve dimensions, eliminating sharp curve flows and reducing flow resistance.
Solution Approach 2:
The patent divides the fluid passage into distinct segments: the first channel that penetrates the valve core and connects the first water connection port to the second water connection port. This segmentation allows each part of the flow path to be optimized independently, creating straighter flow paths with fewer sharp curves, thereby reducing flow resistance while maintaining compact valve structure.
2Loss of energy
If the first channel penetrates the valve core along the radial direction, then the flow resistance is reduced and flow velocity increases, but the channel length through the valve core increases
Solution Approach 1:
The patent optimizes the geometric parameters of the first channel, including its penetration direction (radial or inclined), diameter variations along the length, and curvature radius. By adjusting these parameters, the channel achieves a balance between reduced flow resistance (through smoother flow paths) and controlled channel length, ensuring efficient fluid transport while maintaining reasonable valve core dimensions.
