Flow Regulation Valve Spring Support for Pressure-Independent Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing flow regulation valves for liquid conduction heating and cooling installations face challenges in maintaining consistent flow rates independent of pressure variations and improving flow efficiency.
Innovation Solution
The introduction of a separate spring support for the flow-regulation spring, mounted to the valve insert housing, and a ring element with a diaphragm connected to the second valve body, which interacts with pressures upstream and downstream to maintain constant flow, along with a clear clip mounting mechanism for the ring element, enhances flow regulation and efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a separate spring support is introduced for the flow-regulation spring, then flow efficiency is improved, but device complexity increases
Solution Approach 1:
The spring support is separated from the valve body into an independent component that can be mounted to the valve insert housing. This segmentation allows the spring support to be optimized for flow efficiency while keeping the valve body structure relatively simple, resolving the contradiction between improved flow efficiency and increased device complexity.
2Productivity
If the spring support protrudes axially and radially inwardly beyond the end section of the valve insert housing, then flow efficiency is improved, but manufacturing complexity increases
Solution Approach 1:
The spring support is designed with a dynamic geometry that protrudes axially and radially inwardly beyond the end section of the valve insert housing. This dynamic configuration optimizes the flow path and improves flow efficiency while maintaining manufacturability through standard machining operations.
3Manufacturing precision
If the diaphragm is connected to both the second valve body and the ring element, then flow regulation precision is improved, but device complexity increases
Solution Approach 1:
The ring element serves as an intermediary component that connects the diaphragm to the valve insert housing. This intermediary structure allows the diaphragm to be properly positioned and supported, improving flow regulation precision while distributing the structural complexity across multiple simpler components rather than one complex integrated part.
