Abstract
The invention relates to engineering industry, in particular, to systems for shutoff of liquid feed in case of leakage detection, and to a method for liquid feed shutoff. The provided system and method offer significant advantages when used in water supply and heating networks of residential, public or industrial buildings, and in liquid transporting pipelines. The invented liquid feed shutoff system comprises at least one shutoff valve, at least one control unit, at least one detecting unit and at least one alarm unit. All units of the system are coupled by means of informing radio signals; the control unit is able to send a control signal to the shutoff valve for closing it. Power supply to all components of the system is provided by self-contained power sources. The shutoff valve is able to close automatically upon leakage detection by the detecting unit. Opening of the shutoff valve causes accumulation of energy sufficient for subsequent closure of the valve. The liquid feed shutoff system is designed for reuse and does not require replacement of any components after operation.
