Ventilating Valve Flow Channeling Against Dirt Deposition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ventilating and evacuating valves in conduit systems, particularly in sewerage conduits, are prone to functional impairment due to dirt contamination, which affects the valve mechanism's operation.
Innovation Solution
A ventilating and evacuating valve design that incorporates a channelling means to divert the evacuating flow away from the valve mechanism, protecting it from dirt particles and preventing dynamic pressure on the valve body, thereby maintaining functionality and reducing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the valve mechanism is exposed to the evacuating flow, then the valve can perform its ventilating and evacuating function, but dirt particles in the flow deposit on the valve mechanism and impair its functionality
Solution Approach 1:
A channelling means is introduced as an intermediary element between the evacuating flow and the valve mechanism. This channelling means directs the flow along a predetermined path that bypasses the valve mechanism, allowing the valve to remain exposed to the flow for functional operation while preventing dirt particles from depositing on sensitive components.
2Ease of operation
If the evacuating flow directly contacts the valve body, then the valve can operate, but dynamic pressure from the flow exerts force on the valve body and may affect its operation
Solution Approach 1:
The channelling means serves as a mediator that allows the evacuating flow to pass through the valve assembly without directly impacting the valve body. The flow is channeled along the outer circumference, preventing dynamic pressure forces from acting on the valve body while maintaining operational functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The channelling means effectively prevents dirt deposition on the valve mechanism, ensuring its operational integrity and preventing the evacuating flow from exerting force on the valve body, thus maintaining the valve's functionality and reducing contamination risks.
Implementation Method 1
a channelling means (8) which is configured to guide an evacuating flow at least partially past the valve mechanism
Implementation Method 2
the channelling means prevents the evacuating flow from exerting a dynamic pressure on the valve body

AI summary
The present invention relates to a ventilating and evacuating valve for fluid-guiding conduit pipes or braces. The valve includes a valve mechanism and a floating body which acts on the valve mechanism. The valve mechanism includes a valve body which can be moved into different opening or closing positions in order to open and close a valve outlet; a diaphragm cup; and a roll diaphragm which is arranged between the valve body and the diaphragm cup and can come to rest in different opening or closing positions over aperture openings of the valve body. The valve also includes a channelling mechanism which is configured to guide an evacuating flow past the valve mechanism.
