Intelligent emergency shut down system and a method for emergency closing and regulation of fluid stream in fluid storage and dispensing systems during earthquake

A method for regulating a flow of a fluid stream in fluid storage and dispensing systems, the method comprising steps of:

• providing a valve arrangement at an exit of the fluid storage and dispensing systems to regulate an outflow of a fluid stream, wherein the valve arrangement includes a compressor which sucks in air, compresses the air to a density and supplies the compressed air to a compressed air unit bloated by a connecting air inlet tube, wherein said air is ambient air, and wherein said valve arrangement further comprises a valve elevating means which comprises a rack and pinion system that adjusts vertical height of the valve arrangement;
• detecting a presence of an at least one of a plurality of crisis factors using a plurality of sensors wherein said sensors comprise an acceleration sensor, a contact and light sensor, level meter sensor and a contaminant densimeter;
• processing a data received from the plurality of sensors;
• comparing the processed data with an actual data;
• providing a valve close signal to an actuator in response to a detection of a crisis factor;
• applying an actuation signal to the valve arrangement for a predetermined time upon receiving the valve close signal;
• shutting down the valve arrangement to prevent the outflow of the fluid;
• and informing a remote management system regarding an operating condition of the valve arrangement to take adequate safety measures.
