Pressure Regulator Noise Attenuator Rod Support Against Plate Bending
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gas regulators with noise attenuation devices fail to maintain effective noise suppression due to high pressure forces causing the noise attenuation plates to bend and detach, disrupting the noise reduction function.
Innovation Solution
A fluid regulating device with a noise attenuation assembly retained by a plurality of rods, where each rod has a front end, middle portion, and rear end, equidistantly disposed around the outer edges of multiple plates within a cylindrical body, distributing stress and securing the plates to prevent bending and enhance noise suppression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rod is used to support noise attenuation plates, then the device structure is simple, but the plates bend and detach under high pressure forces
Solution Approach 1:
The single rod support is segmented into multiple rods (at least three) equidistantly distributed around the cylindrical body. Each rod independently supports the noise attenuation plates, distributing the high pressure forces across multiple points rather than concentrating them on a single rod, thereby preventing plate bending and detachment while maintaining structural reliability.
2Reliability
If multiple rods are used to support noise attenuation plates, then plate stability is improved, but the device complexity increases
Solution Approach 1:
The multiple rods are positioned at specific locations equidistantly around the cylindrical body, creating localized support points that strategically distribute stress. This localized quality approach ensures that each rod supports a specific sector of the plates, providing optimal stability while minimizing overall structural complexity through symmetric, regular spacing.
3Device complexity
If stress is concentrated at the center of plates, then the support structure is simple, but the plates bend under high pressure
Solution Approach 1:
The support structure transitions from a single central rod (one-dimensional support) to multiple rods distributed in a circular pattern (two-dimensional radial distribution). This dimensional change distributes stress from the plate centers across multiple peripheral attachment points, preventing stress concentration and plate bending while maintaining structural simplicity through symmetric geometry.
