Automatic fluid spill prevention and shut off safety valve

A fluid flow control system that detects and prevents fluid leakage comprising a valve system wherein said valve system comprises;

• a. a main fluid inlet,
• b. a main fluid outlet,
• c. a plurality of chambers, wherein said plurality of chambers comprises a first chamber, a second chamber and a third chamber
• d. a plurality of internal paths, wherein said plurality of internal paths comprises a first internal path for a flow, wherein said first internal path is located between the first chamber and the second chamber,
• e. a plurality of sub-systems, wherein said plurality of subsystems comprises a pressure regulator sub-system, a continuous measuring sub-system and a automatic shut off sub-system, wherein said pressure regulator sub-system comprises a first device that regulates the flow by means of a first device displacement with respect to said first internal path;
• and
• f. wherein said automatic shut off system comprises a second device that regulates the flow by means of a second device displacement, wherein said second device displacement is induced by said first device displacement that overrides the first device pressure and flow controlling action at an adjustable flow rate,
• g. wherein said plurality of internal paths comprise a second internal path for the flow located between the second chamber and third chamber;
• and
• wherein said pressure regulator sub-system comprises a first resilient mechanism having reciprocal motion, wherein said first resilient mechanism is mechanically connected to said first device and actuates said first device displacement in response to the flow at the second internal path, and wherein said first device displacement is arranged to control the flow at said first internal path and gradually closes or opens said first internal path, wherein said automatic shut off system comprises a third device that regulates the flow, wherein said third device controls the flow at said second internal path by means of closing or opening said second internal path, wherein said third device is activated by an external actuator, wherein said external actuator is mechanically coupled to a pressure normalization and timer sub-system, wherein the pressure normalization and timer sub-system comprises a differential pressure regulator valve and a timing device, wherein said timing device is selected from a fluid timing device, a mechanical timing device, and an electrical timing device.
