Abstract

Device for the control of filling of tanks, characterized essentially by the fact of consisting of a valve body located superiorly inside the tank and provided with a liquid outlet connected to the supply network, in whose body is an elastic discoidal valve substantially horizontal relatable with a seat formed by the edge of the end of a conduit that comes from the inside of the valve body to the outside and empties into the tank, the device comprising a float threaded displaceably on a vertical tube attached inferiorly to the bottom of the valve body, whose float carries on its internal face a permanent magnet acting through said tube on a metal rod guided inside the tube and provided at its upper end with a shutter that, when the liquid level of the tank rises and the magnet drags the stem, closes a central hole in the valve that is maintained applied against its seat by the pressure of the liquid acting on the bottom of the valve body below it and reaching said bottom through a space formed around the aforementioned duct and above the valve, and through a perforation of this, all in such a way that, when the level of the liquid descends and lowers the float dragging with the magnet to the stem and, consequently, the obturator discovers the central orifice of the valve, the pressure of the liquid of the bottom of the valve body decreases and the pressure of the liquid of the space located on the valve separates it from its seat, allowing the passage of the liquid through the conduit to the interior of the tank.
