Pressure Lock Mechanism for Rapid Gas Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas leak detection methods in gas systems are inefficient, often requiring up to half an hour to detect leaks, and can lead to false senses of security due to prolonged measurement times and the need for pressure equalization.
Innovation Solution
A pressure lock system is introduced, which temporarily blocks the flow of gas through the regulator, allowing for rapid leak detection by maintaining equal pressure throughout the system, and can be integrated with a directional gas leak detector to identify the location of leaks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pressure equalization is used for leak detection, then measurement accuracy is improved, but detection time increases significantly
Solution Approach 1:
The pressure lock pre-compresses a volume of gas and stores it under pressure before the actual leak detection is needed. When detection is required, this pre-compressed gas is rapidly released to equalize pressure throughout the system immediately, eliminating the lengthy pressure equalization wait time while still enabling accurate leak detection.
Solution Approach 2:
The system divides the gas storage function from the leak detection function by introducing a separate pressure lock component. The pressure lock handles the time-consuming gas compression and storage separately, allowing the main system to perform rapid leak detection without being burdened by the slow pressure equalization process.
2Reliability
If frequent leak testing is performed, then safety is improved, but user convenience deteriorates due to long testing time
Solution Approach 1:
The pressure lock maintains a ready supply of pre-compressed gas, enabling the system to perform rapid leak tests without requiring lengthy pressure equalization periods. This reduces each test to a matter of seconds, making frequent testing practical and encouraging users to test before every gas system use, thereby improving safety.
3Measurement precision
If manual pressure equalization waiting is required, then measurement accuracy is improved, but user comfort deteriorates due to lack of clear indication
Solution Approach 1:
The pressure lock provides immediate visual feedback through its indicator mechanism that shows when pressure equalization is complete and the system is ready for accurate leak detection. This eliminates the uncertainty and waiting period, giving users clear information about system status while ensuring measurement accuracy is achieved.
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 pressure lock system enables immediate leak detection, reducing the time required to identify leaks to less than a minute, and when integrated with a directional gas leak detector, allows for precise location of leaks, enhancing user safety and encouraging frequent leak testing.
Implementation Method 1
The pressure lock functions by compressing a volume of the gas in the gas system and thereby increasing the pressure to above the predetermined output pressure
Implementation Method 2
By blocking the inflow of gas, the pressure lock ensures that the pressure is the same everywhere between the regulator and the gas consumer of the gas system

AI summary
A pressure lock for a gas system with a regulator, the pressure lock comprises a pressure lock body to be fluidically connected in said gas system, whereby gas can pass from a chamber in the body via lock connection means to the gas system and activation means for delivering gas from said pressure lock body and into the gas system thereby providing a lock-up pressure, whereby the gas from said pressure lock body provides an increased pressure in the gas system, whereby the regulator is blocked for a short period of time thus allowing the detection of leaks in the gas system downstream of the regulator.
