FIELD: machine building.
SUBSTANCE: automatic safety system consists of system of sensors, of electric valve and of protected object. The protected object is connected to an actuating device. A signal controlling the actuating device is transmitted from a control device. The latter corresponds to the electric valve. The system of controlling the actuating device consists of a device for electric valve electric start-up. The device for electric start-up is mounted on a cover, The cover is fastened in an upper part of the electro-valve case and has two contacts: the central contact and contact "Case". The actuating device is actuated with a switch button only under an emergency mode. The electric valve is coupled with the system of dangerous zone probing. The latter consists of sensors set to excess of maximum permissible concentration of chemically hazardous substances and of a probe. The probe is set to excess of maximum permissible levels of radio-active substances. A micro-processor processes signals and transmits the control signal for electric valve start-up.
EFFECT: increased efficiency of process equipment protection from emergencies owing to raised performance and reliability of system actuation.
