Gas-powered appliances—like stoves and water heaters—depend on gas storage tanks. But if a pipe connected to the tank suddenly bursts or experiences abnormal pressure, gas can dangerously leak. To prevent this, many tanks use an “overflow valve” that automatically shuts off the gas flow when pressure spikes. However, once shut off, current valves must be physically removed and professionally reset—posing safety risks and inconvenience to users.
Invention
This patent introduces a smarter overflow valve that includes a built-in reset function. If an emergency occurs (like a pipe rupture), the valve still automatically shuts off gas flow to prevent leaks. But unlike older models, this valve can be easily reset by pressing a button, once the issue is resolved—no need to remove it or call a technician.
What’s New
The key innovation is a push rod reset mechanism that directly interacts with the valve’s internal stopper. When the gas flow is shut off, the push rod can be manually activated to move the stopper back into position. A spring and anti-slip design ensure safe, reliable operation. This compact reset system is integrated into the valve body without interfering with other safety functions.
Benefits
- Fast and easy reset after an emergency—no tools or professionals required
- Prevents gas leaks during and after abnormal events
- Minimizes downtime of gas systems
- Reduces risk of improper handling by end-users
Broader Impact
This resettable overflow valve improves gas safety for homes, businesses, and industrial users. It offers greater convenience and peace of mind, encourages safer DIY maintenance, and reduces reliance on costly service calls. Over time, this could make gas systems more sustainable and user-friendly by simplifying emergency recovery and minimizing gas waste.
