Two-Stage Gas Pressure Regulator for Precise High-Pressure Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressure regulation devices for compressed gases often require multiple stages and complex mechanisms to achieve precise pressure adjustment, which can be cumbersome and inefficient, especially when dealing with high initial pressures exceeding the required application pressure.
Innovation Solution
A two-stage pressure-regulating device with a first stage regulator for coarse adjustment and a second stage regulator for fine-tuning, utilizing a piston and valve mechanism with adjustable biasing members and threaded connections to control gas flow and pressure, allowing for precise pressure reduction from high initial pressures to suitable lower pressures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-stage pressure regulator is used, then the device complexity is reduced, but the pressure adjustment precision deteriorates
Solution Approach 1:
The pressure regulation function is divided into two independent stages: a first stage regulator for coarse pressure reduction and a second stage regulator for fine pressure adjustment. This segmentation allows each stage to specialize in a specific adjustment range, achieving high precision without requiring a single complex regulator
2Measurement precision
If a two-stage pressure regulator is used, then the pressure adjustment precision is improved, but the device complexity increases
Solution Approach 1:
The first and second stage regulators are merged into a single integrated device with shared components including a common body, integrated valve mechanisms, and unified biasing member adjustment systems. This merging achieves precise two-stage pressure regulation while minimizing the increase in device complexity
3Adaptability or versatility
If high initial gas pressures are handled, then the applicability range is expanded, but the device complexity increases
Solution Approach 1:
The pressure regulation range is segmented into two distinct stages: the first stage handles large pressure reductions from high initial pressures, while the second stage manages fine adjustments to achieve target pressures. This segmentation enables the device to handle high initial pressures effectively without requiring a single overly complex regulator

Implementation Method 2
a first biasing member positioned to apply a force the first piston in the upstream direction
Implementation Method 3
a second stage pressure regulator positioned downstream from first stage pressure regulator and in fluid communication therewith, the second stage pressure regulator being configured to decrease gas pressure of a gas flowing therethrough
Implementation Method 4
an intermediate regulator body threadedly connected to the expansion body and securing at least a portion of the first stage pressure regulator therebetween in a manner that changing distance between the expansion body and the intermediate regulator body changes an amount of pressure decrease produced by the first stage regulator

AI summary
Embodiments described herein relate to a pressure-regulating device, systems that include the device, and related methods. For example, the pressure-regulating device may receive gas from a gas supply at a first pressure (e.g., on a supply side of the pressure-regulating device) and may regulate or reduce the pressure of the received gas to a selected or suitable second, different pressure.
