FIELD: construction.
SUBSTANCE: proposed method comprises initiation by pickup signal for shutoff of water feed to water supply line and room draw-off valves in emergency. Said signal is generated at standard conditions as well. Note here that after initiation actual situation is evaluated during the procedure terminated in emergent and standard conditions. Said signal is generated by water motion in the line. Proposed device comprises shutoff valve arranged at pipeline and pickups interconnected via signal processing unit. One of said pickups arranged at pipeline represents a water motion sensor while another pickup is integrated with draw-off valves and represents the valves opening actuator.
EFFECT: simplified design and enhanced operating performances.
