Abstract
A leak detection and shut-off system designed to detect a liquid leak or excess moisture at key locations in a piping system. The system includes a wireless detector comprising a sensor and transmitter which sends a signal to a receiver. The receiver triggers a control board to activate the closing of a valve to stop the flow of the liquid into the internal system or a block of a closed system.
Claims4
A leak detection and shut-off system comprising:
- at least one moisture detector;
- said moisture detector including a sensor for sensing the presence of moisture and a transmitter;
- said sensor generating a sensor signal when moisture is sensed;
- said transmitter receiving said sensor signal, and, in response thereto, generating a transmitted signal indicative of the detection of moisture;
- a receiver remote from said detector;
- said receiver receiving said transmitted signal and generating a shut-off signal in response to said transmitted signal;
- and
- a solenoid activated valve having a solenoid switch and a valve element;
- said valve element being movable between an opened position and a closed position in response to activation and deactivation of the solenoid switch;
- the solenoid of said valve receiving said shut-off signal from said receiver, and in response thereto, moving said valve from its open position to its closed position.

In a piping system comprising piping through which liquid passes and a plurality of appliances which use the liquid;
- the improvement comprising a leak detection and shut-off system comprising:
- at least one moisture detector positioned adjacent said piping at a desired position along said piping;
- said moisture detector including a sensor for sensing the presence of moisture and a transmitter;
- said sensor generating a sensor signal when moisture is sensed;
- said transmitter receiving said sensor signal, and, in response thereto, generating a transmitted signal indicative of the detection of moisture;
- a receiver remote from said detector;
- said receiver receiving said transmitted signal and generating a shut-off signal in response to said transmitted signal;
- and
- a solenoid activated valve positioned near a start of said piping system and having a solenoid switch and a valve element;
- said valve element being movable between an opened position and a closed position in response to activation and deactivation of the solenoid switch;
- the solenoid of said valve receiving said shut-off signal from said receiver, and in response thereto, moving said valve from its open position to its closed position.
