Porous Filter for Gas Pressure Regulator Vent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gas pressure regulators in dirty environments, such as animal confinement buildings, often become clogged due to dust and moisture, leading to reduced reaction times and incorrect operation, as the small vent holes are prone to blockage by fine particles and condensation.
Innovation Solution
A gas porous filter, made from materials like foam, interlocking metallic shavings, steel wool, or porous cloth, is positioned adjacent to the vent to prevent dust and debris from blocking the vent opening, allowing for easy cleaning or replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a small vent hole is used in the gas pressure regulator, then the regulator can be compact and efficient, but the vent hole becomes easily clogged with dust and debris in dirty environments
Solution Approach 1:
The patent applies a porous filter material positioned over the vent hole that allows gas molecules to pass through while blocking dust particles and debris. The porous structure provides multiple flow paths that maintain ventilation functionality while preventing clogging, resolving the contradiction between small vent size and blockage resistance in dirty environments like animal confinement buildings.
2Reliability
If the gas pressure regulator is exposed to the atmosphere for ventilation, then it can operate correctly under varying air pressure, but dust and moisture accumulate on the regulator causing clogging
Solution Approach 1:
The patent introduces a porous filter as an intermediary element between the atmosphere and the vent hole. This filter mediates the interaction by allowing beneficial gas flow and pressure equalization while blocking harmful dust particles and moisture. The filter maintains atmospheric exposure for proper operation while protecting against contamination in dirty environments.
3Reliability
If the vent hole is covered to prevent dust accumulation, then clogging is reduced, but the regulator cannot vent properly to the atmosphere
Solution Approach 1:
The porous filter material provides a covered appearance that prevents dust accumulation while maintaining ventilation functionality. The porous structure allows gas molecules to pass through freely for proper pressure equalization and venting operation, while the external surface prevents dust and debris from entering and clogging the vent hole.
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 gas porous filter effectively prevents clogging of the vent opening, ensuring the gas pressure regulator operates correctly even in harsh, dirty conditions by allowing airflow while filtering out dust and debris.
