FIELD: machine building.
SUBSTANCE: invention relates to mechanical engineering, in particular to safety devices of safety systems. Automatic safety device of safety systems in emergency situations contains a system of sensors and an electrovalve, whose housing is located vertically, and the device for electrolessing the solenoid valve is mounted on the locking and clamping nut, inside the body of the solenoid valve, coaxially with it, a piston fixed in the standby state by a latch located perpendicular to the axis of the piston and fixed in the opening of the piston and in two coaxial holes with it in the body of the solenoid valve, and when the solenoid valve operates, the piston performs the function of a cutter, which cuts off the retainer, made in the form of annealed wire with a diameter ∅ 1.0 mm, with one end of the clamp fixed to the body of the solenoid valve, and the other at the end of the trigger lever, the actuator is only actuated in the emergency mode from the power button entering the actuator start-up system. System for sounding a hazardous area includes, sensors configured to exceed the maximum permissible concentrations of chemically hazardous substances present in this zone, and a probe configured to exceed the maximum permissible levels of radioactive substances, the signals from which are fed to a common microprocessor that processes these signals and issues a control signal to turn on the solenoid valve.
EFFECT: increase the effectiveness of protection of technological equipment from emergency situations by increasing the speed and reliability of the system's operation.
