Valve Core Segmentation and Inversion for Water Purification Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional valve cores experience leakage due to back pressure and continuous water pressure on water purification devices when closing, leading to premature wear and unnecessary expenses from leak detection systems.
Innovation Solution
A novel valve core design with a redesigned flow channel and communication mode between the base, fixed valve plate, and movable valve plate, ensuring liquid tightness and preventing mixed purified and raw water by strategically positioning water inlet and outlet channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valve core uses a conventional flow channel design, then the water purification device can be installed, but the device sustains double pressure (back pressure and continuous water pressure) causing leakage and premature wear
Solution Approach 1:
The valve core is divided into multiple functional components: a base with inlet/outlet channels, a fixed valve plate with a flow channel, and a movable valve plate. This segmentation allows the flow channel to be strategically positioned and directed, enabling the outlet to face away from the water purification device and eliminate back pressure effects on the device.
Solution Approach 2:
Instead of having the outlet channel face the water purification device as in conventional designs, this invention inverts the orientation so the outlet faces away from the device. This reversal of direction prevents back pressure from acting on the purification device, resolving the harmful pressure effect while maintaining proper water flow control.
2Ease of operation
If the valve core closes the flow channel, then water flow is controlled, but back pressure is generated on the water purification device causing leakage
Solution Approach 1:
The outlet channel is oriented to face away from the water purification device rather than toward it. This inverted configuration allows the movable valve plate to close the flow channel effectively while preventing back pressure from being transmitted to the purification device, thus maintaining operational control without causing leakage.
3Productivity
If water inlet and outlet channels are positioned conventionally, then the valve core functions, but purified water may be mixed with raw water
Solution Approach 1:
The valve core structure segments the water flow paths into distinct channels: raw water inlet channels, purified water outlet channels, and intermediate flow channels. This segmentation, combined with the strategic positioning of the outlet channel facing away from the purification device, ensures complete separation between raw and purified water streams, preventing any mixing while maintaining efficient flow control.

AI summary
A valve core includes housing, which is a hollow cylindrical structure with both ends defined as an open end and a through end respectively; a base mounted on the housing to close the open end of the housing; a fixed valve plate mounted on the base, which is unable to rotate relative to the base; a movable valve plate which is rotationally arranged on the fixed valve plate; a manipulation assembly, one end of which is configured on the movable valve plate to manipulate the movable valve plate to rotate relative to the fixed valve plate, and the other end of which is extended to penetrate the through end of the housing.
