DETAILED DESCRIPTION OF THE INVENTION A new drainage valve that is used manually with automatic opening, just before the overflow or spill of the liquid by the upper edges of the container, is used even with the traditional systems of drainage in the washbasins in the home, as are the decorative ones , old, marble, etc., whose characteristic is that they do not have upper holes of overflow. When the drain is free or open the liquid is removed freely; but when the elimination is prevented by means of a plug or other element, the water continues to flow through the supply and causes the accumulation of liquid in the container whose level continues to increase until it reaches the height of spillage of the contents towards the floor, causing a flood zone in some cases with severe damage.

When the valve of the present invention remains closed a container container accumulates liquid, alternatively a small flow thereof passes through holes associated with the valve guide tube in order to fill an internal lower reservoir of cylindrical shape, when the liquid reaches a pre-set height in the reservoir, the magnets that hold the valve body will not have enough force to retain the weight of the column of liquid or accumulated water, then the valve body slides down by gravity and allows the exit of the accumulated liquid and at the same time the internal cylindrical container is drained through a check or check valve, once the containers are empty, the valve is kept in its open position, in standby If you manually return to the closed position and another amount of accumulated water activates it automatically to the open position to carry out another drain of the basin or container containing liquid, automatic opening prevents deliberate spillage.
