High-Pressure Gas Regulator Bypass Valve and Leak Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-pressure gas supplying apparatuses face issues such as valve seat damage due to high flow rates, increased leaks, and the need for complete repair when safety valves operate, as well as the inability to reuse condensate water or gas from leaks.
Innovation Solution
The apparatus includes a main flow path, a regulator, a first inlet valve, a bypass flow path, a second inlet valve, and a leaking gas discharge unit, which minimizes impact on the valve seat by gradually discharging leaking gas and using a collector to reuse condensate water and gas produced by the Joule-Thomson effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If gas is applied to the regulator at a high flow rate, then the gas supply efficiency is improved, but impact is exerted on the valve seat of the regulator, causing damage and increased leaks
Solution Approach 1:
The inlet valve is divided into a main inlet valve and a bypass inlet valve, creating separate flow paths. The bypass inlet valve provides an alternative route that reduces impact on the main valve seat, allowing high flow rates without damaging the primary valve seat while maintaining gas supply efficiency.
2Object-affected harmful factors
If the safety valve operates to discharge leaking gas, then the safety issue is resolved, but the entire gas supplying apparatus needs to be repaired and gas service must cease
Solution Approach 1:
The leaking gas discharge function is extracted from the safety valve and assigned to a dedicated leaking gas discharge unit. This unit can continuously and gradually discharge leaking gas without requiring the safety valve to operate, allowing gas service to continue while safely managing leaks.
Solution Approach 2:
The leaking gas discharge unit acts as an intermediary between the regulator and the environment, providing a controlled path for leaking gas to be gradually discharged. This prevents the need for complete system shutdown while maintaining safety.
3Reliability
If the valve seat of the regulator is replaced to solve the fundamental problem, then the reliability is improved, but gas service needs to be ceased and the apparatus needs to be repaired
Solution Approach 1:
The bypass inlet valve is activated in advance when leaks are detected, providing an alternative flow path before the main inlet valve needs to be replaced. This preliminary action allows gas service to continue during maintenance operations.
Solution Approach 2:
The bypass inlet valve maintains continuous gas supply to the regulator even when the main inlet valve is being replaced or repaired. This ensures that gas service continues without interruption, maintaining the continuity of useful action during maintenance.
