DETAILED DESCRIPTION OF THE INVENTION

A novel drain valve that is used manually with automatic opening, just before the overflow or spillage of the liquid through the upper edges of the container, is used even with the traditional drainage systems in the basins at home, as are the decorative , antique, marble, etc., whose characteristic is that they do not have superior overflow holes. 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 content 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 guide tube of the valve in order to fill an internal lower reservoir in a cylindrical manner, when the liquid reaches a preset height in the reservoir, the magnets that hold the valve body will not be strong enough to retain the weight of the accumulated liquid or water column, then the valve body slides down by gravity and allows the accumulated liquid outlet and at the same time the internal cylindrical container is drained through a check or check valve, once the containers are empty, the valve will it keeps in its open position, waiting for it to be returned manually to the closed position and that another amount of accumulated water makes it actuate automatically to the open position to make another drain of the basin or container that contains liquid, with the Automatic opening prevents deliberate spillage.

Figure 3 represents the second group of components of the automatic valve of the present invention consisting mainly of the support of the valve (6), tubular body or housing (1 1) and the adjustment cover (15); The valve support (6) has a round donut-type lid with perimeter drainage holes for the drain, regularly distributed at every 90 ° that allow the flow of liquid downwards, said holes marked with (6a, 6b, 6c and 6d ) when the valve is in operation the holes are occluded with the upper seal not shown, the magnet (7) or the spring is located interchangeably in the center of the round cover, the two elements (spring magnet) can also be included, The washer-type magnet that allows the free passage of the guide tube (5) of the valve, this tube conducts a certain flow that fills a calibrated receiver receiver downstream to open with the weight of a certain volume of water or liquid in said reservoir that is located in the inner part of the tubular body or housing (1 1). The valve support (6) covers and holds some of its own and associated elements of the upper end of the housing (1 1) such as the upper magnet (7) attached to the inner face of the cover of said housing, the guide tube (5) of the valve, the seal (9) of the same located inside the housing (1) and attached to it, the references (6 a and 6b) indicate the drainage space of the drain holes; The housing (1 1) has an internal flat surface (1 1 a) that defines the empty space where the seal (9) is placed and the valve receiving tube (not shown), the lower end of the housing has an external thread (12) where the internal thread (15a) of the adjustment cover (15) is coupled, in greater detail a plan view of the lower surface (16) of the cover (15) is shown, with a plurality of holes ( 16a, 16b, 16c and 16d) regularly distributed at every 90 ° allow the flow of liquid through them and through them the valve discharge, the central section (17) serves as support for actuating the check or check valve that is not shown.

Figure 4 shows the exploded view of the valve body that is located inside the casing or tubular body (not shown), the plan view indicates the axial location of each of the component elements, such as the receiving cylinder (10) , the magnet (20), the upper pin (10 a) and the discharge nozzle of the receiving cylinder that is occluded by means of the round body of the check or check valve (13) which is calibrated by means of the contact end (13 a) thereof, it should be mentioned that the check valve (13) is located inside the valve receiving cylinder to conveniently occlude the opening of the outer nozzle; on the other hand the lower magnet (20) is shaped like a washer and is placed on the spike (10 a) of the receiving tube or cylinder; The location of the plurality of magnets allows the automatic valve of the present invention to remain in the closed position while the liquid accumulates in the sink and receiving cylinder, at the same time the holes that fill the receiving cylinder of the valve allow the passage of liquid gradually so that it reaches a full or full height regulated within it, with the weight of the accumulated volume, the valve opens automatically when sliding down, because the weight of the volume of the liquid manages to overcome the magnetic force of union between the magnets and allows the fall of the receiving tube and the opening of the check or check valve to allow the evacuation of liquid from the receiving tube and the washbasin, because the upper seal allows the liquid to pass through the drain holes already through the valve holder. Figure 5 shows the automatic drainage device of the present invention in the open position, it is to highlight the position of the check or check valve (13) and the cover (1) together with the upper seal (3), in this position allows the flow of liquid through the holes in the valve support and the external discharge nozzle (14) that dislodges through the adjustment cover (15); the drainage of the volume of liquid from the sink passes outside the tubular body or housing (11) and downstream of the tube (35) is combined with the liquid that is discharged from the receiving cylinder (10), thereby allowing complete drainage of the sink. In the open position of the device the base cylinder (4) of the cover is outside or above the upper edge of the valve support, thereby separating the seal (3) from said edge and from the retaining flange (30 ) or support washer to the drain pipe, the magnets (7 and 8) interact to keep the valve in the open position, are located in the proximity position that allow the interaction of each of its fields to keep the housing in a raised position , in the closed position of the valve they will have a position of moving away or displaced downwards, whose sliding axis is the guide tube (5) of the valve. In the opening position the interaction relationship between the intermediate (8) and lower (20) magnets is distancing and with minimal interaction force.

Figure 6 shows the automatic drainage device of the present invention in the closed position, it is to highlight the position of the check or check valve (13) and the cover (1) together with the upper seal (3), In this position, the flow of liquid through the holes in the valve support and the discharge nozzle (14) that dislodges through the adjustment cap (15) is not allowed. The cylinder or base (4) of the upper cover (1) is located inside or below the upper edge of the drain pipe (35) or beyond the position of the support washer (30), the seal (3 ) occludes the drain holes of the valve holder (6) and does not allow flow to the drain; on the other hand, the lateral holes of the support (6) are free and allow the filling of the receiving tube or cylinder (10) through the guide tube (5) whose lower end extends to beyond the upper end of the receiving tube; the round-type magnets (7 and 8) now far apart do not interact to keep the valve in the closed position, they are located in the away position that does not allow the interaction of each of its fields to keep the housing in a raised position, in the position closed from the valve will have a position of moving away or moved down, whose axis of sliding is the guide tube (5) of the valve. In the closed position the interaction relationship between the intermediate (8) and lower (20) hands is of proximity to allow the interaction of their respective fields and generate an out of retention which must be overcome by the weight of the volume of the liquid received in the cylinder (10) that when filled causes the automatic separation of the valve to keep it in the open position in which the discharge flow is allowed to drain the upper tank or sink, tub, etc., the drainage system performs vertical displacements whose sliding axis is the guide tube (5) of the valve. In the closed position the check or check valve (13) is regulated by the position of the adjustment cap (15) and occludes the duct defined by the nozzle (14), the weight of the volume of the liquid inside the receiving tube or cylinder (10) moves it downwards releasing the nozzle orifice (14) to allow the drainage of said tube. The seal (9) functions as a retainer and prevents the entry of liquid into the housing (1 1) and thus allows free vertical sliding of the receiving tube (10) of the valve.
