Electronic Flow Valve Outlet Geometry for Quiet, Clean Regulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic valves suffer from mechanical vibrations and noise due to turbulent flow throttling, and accumulate impurities in non-renewed fluid contact areas due to blind housings.
Innovation Solution
An electronic valve with a linear drive motor and a piston having a variable geometry profile and a guiding appendage, supported by a guiding housing that maintains coaxiality and is immersed in the liquid flow, with radial and transverse liquid outlets to reduce pressure loss and prevent impurity accumulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a blind housing is used to support and guide the shaft, then the shaft is supported and guided, but impurities accumulate in the area due to non-renewed fluid contact
Solution Approach 1:
The guiding function is extracted from the blind housing and transferred to a separate guiding element (such as a guide ring or guide surface) that is exposed to the fluid flow. This allows the housing to be open rather than blind, enabling fluid renewal and preventing impurity accumulation while maintaining shaft guidance through the separate guiding element.
Solution Approach 2:
A guiding element acts as an intermediary between the shaft and the housing. This guiding element is positioned to be exposed to fluid flow, allowing it to provide guidance while the fluid can flow around it, preventing impurity accumulation in the guidance area.
2Ease of operation
If the piston is displaced by a motorized shaft from one end, then the piston position is controlled, but mechanical vibrations and noise are produced due to turbulent flow throttling
Solution Approach 1:
The invention appears to address vibrations and noise by modifying the flow characteristics rather than using vibration-based solutions. The guiding element and housing configuration are designed to reduce turbulent flow and throttling effects that generate noise and vibrations during piston displacement.
Solution Approach 2:
The geometry of the guiding element and housing is optimized to change flow parameters (velocity, pressure distribution) in a way that reduces turbulent throttling. The guiding surface shape and positioning are designed to minimize sudden flow restrictions that cause noise and vibrations.
3Stability of the object's composition
If the guiding housing passage geometry is complementary to the guiding appendage, then coaxiality is maintained throughout displacement, but the structure becomes more complex
Solution Approach 1:
The guiding function is segmented into a separate guiding element rather than being integrated into the housing structure. This simplifies the housing design while maintaining coaxiality through the dedicated guiding element that works in conjunction with the piston appendage.
Solution Approach 2:
The guiding element serves multiple functions: maintaining coaxiality, supporting the piston, and being positioned to allow fluid flow. This multi-functionality reduces the need for additional components, simplifying the overall structure despite the precise geometric requirements.
