Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure regulators generate significant noise due to hypercritical pressure drop and turbulence, leading to complex and costly silencing solutions that are difficult to install, replace, and maintain, as they require complete disassembly.
Innovation Solution
A pressure regulator with an axially symmetric body and a flow dividing silencing element that can be easily inserted and removed, comprising a cylindrical wall with holes or wire mesh, allowing for noise reduction without disassembling the regulator, and enabling interchangeable silencing types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If sound absorption devices (porous cartridges) are used to reduce noise, then noise reduction is achieved, but device complexity and cost increase due to larger regulator body required to accommodate cartridges
Solution Approach 1:
The invention extracts the silencing function from the main regulator body by using a separate, removable silencing element that can be independently installed or removed. This allows noise reduction without permanently increasing the complexity of the regulator structure, as the silencing component is modular and can be adapted or replaced without affecting the core regulator design.
Solution Approach 2:
The silencing device is segmented into a separate removable element rather than being integrated into the regulator body. This segmentation allows the silencing function to be independently optimized and replaced without modifying the regulator structure, thereby reducing overall device complexity while maintaining noise reduction effectiveness.
2Object-affected harmful factors
If flow dividing silencing devices are installed to reduce noise, then noise production is reduced, but ease of operation deteriorates because complete disassembly is required to install or replace silencing devices
Solution Approach 1:
The silencing element is designed as a separate, removable component that can be independently handled. This segmentation enables the silencing device to be installed or replaced without disassembling the regulator body, significantly improving ease of operation and maintenance while maintaining the noise reduction functionality.
Solution Approach 2:
The silencing element is designed to be dynamically removable and replaceable rather than fixed permanently. This dynamic design allows users to easily install, remove, or replace silencing elements based on operational needs without requiring complete regulator disassembly, thereby improving ease of operation.
3Object-affected harmful factors
If complex silencing devices are used to reduce noise, then noise reduction is achieved, but ease of repair deteriorates due to difficulty in replacing silencing devices
Solution Approach 1:
The silencing element is segmented as a separate, self-contained component that can be independently removed and replaced. This segmentation dramatically simplifies repair operations, as technicians can replace silencing elements without disassembling the regulator body or other components, thereby improving ease of repair while maintaining effective noise reduction.
Solution Approach 2:
The silencing function is extracted as a separate removable element that can be independently serviced. This extraction allows the silencing device to be easily removed, inspected, and replaced without affecting the regulator system, significantly improving ease of repair and maintenance operations.
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 solution effectively reduces noise by dividing the gas flow into smaller streams, minimizing assembly complexity and cost, while allowing for easy maintenance and adaptation of silencing devices.
Implementation Method 1
a flow dividing silencing element that can be easily inserted and removed, comprising a cylindrical wall with holes or wire mesh, allowing for noise reduction by dividing the gas flow into smaller streams
Implementation Method 2
Pressure regulators currently used are also commonly known as 'pressure reducers' because their regulating action is achieved by reducing the gas delivery pressure through laminar flow elements
Implementation Method 3
The controlling and regulating means comprise at least one shutter, actuated by spring and diaphragm systems which enable the shutter to slide on its shaft
Implementation Method 4
a pilot device which measures the pressure of the gas upstream and downstream of the regulator and controls the shutter actuating diaphragm accordingly
Implementation Method 5
The gas flow is shut off by means of a ring seal or pad, normally fixed to the mobile shutter and adapted to engage the housing
