DETAILED DESCRIPTION OF THE INVENTION

[0038] The present invention has several aspects, tending to improve the seal of the outlet valve of the urinals without water use. Said valve consists of a main body which in its upper part comprises a means of attachment to be fixed to the urinal. On the other hand, in its lower part also has a means of attachment to be fixed to the pipe that will hydraulically connect the main body of the valve, to the exit to the drainage. At the upper end, this main body comprises a disk with perforations, where the urination is to be directly impinged, when the user is urinating.

[0039] In one of their preferred modality, these fastening means consist of external threads for fixing to the urinal and the tube toward the outlet to the drain, by means of nuts.

[0040] In the interior, slightly below the middle, the structure comprises a disc with a central orifice to direct the urine towards the tube that connects to the drainage. This disk by its lower face has a tubular projection that is going to be obstructed or released by the component that would come to be the valve itself, although by extrapolation we call valve to the valve itself together with the main body with their respective threads, lower disk with its tubular projection and the upper disk with holes.

[0041] Said lower inner disk, at the top, has a very open conical configuration to facilitate the concentration of the urine in the center, and the subsequent evacuation towards the tube that will lead to the drainage.

[0042] In this aspect there are several modalities that will depend on the ease of manufacture and other factors. One modality of this valve is that the main body with its ropes or threads, as well as its upper disk with holes and the lower one with its central orifice and its central tubular projection are in one piece or, in other words, it is a monolithic piece.

[0043] However, in another preferred modality, for ease of manufacture and ease of maintenance, the main body is comprised of three parts, two telescopic cylinders, one shorter internal and the other external more longer. The third piece is the lower inner disc.

[0044] The longer outer cylinder is the one that comprises the upper outer threads for attachment to the urinal by means of a nut and the lower one for attachment of the main body of the valve to the tube which will lead the urine to the drainage pipe.

[0045] The shorter telescopic tube is the one that comprises the upper disk with holes, fixed or forming a single monolithic body and it is in this shorter telescopic inner cylinder where the inner lower disc is embedded with the upper face in open cone configuration and with the underside with tubular projection.

[0046] The lower tubular projection of the lower inner disc in turn has transverse cylindrical projections where will be install, depending the modality, the fulcrum of the rocker or one of the ends of the elastic bodies which maintained in closed position the valve itself, when this corresponding to a piston valve.

[0047] FIG. 1 illustrates the modality in which the urinal valve consists of a rocker valve 4 in the closed position, showing the lines representing the flow of gases 2.

[0048] In this figure the external telescopic tube 1 can be visualized with the thread Top 8 and the lower thread 9. The inner telescopic tube 3 has the lower disc 10 with the top face 5 in very open conical configuration and the tubular projection 6 on the underside of said disc.

[0049] The rocker valve 4, itself has the fulcrum 7 in the lateral projections of the tubular projection of the lower disk 10.

[0050] FIG. 2 illustrates the details of the rocker with the component in which the counterweight 20 is located and the component where the sealing element 21 is located, with the fulcrum 22 where the rocker is pendulously attached to the lateral projections of the lower tubular projection of the lower inner disc. In counterweight in the element 20 has a magnitude such that it maintains the rocker with the component with the sealing element slightly in contact with the seat comprised in the lower tubular projection of the lower inner disc. While this light contact would not seal completely to prevent passage through the rocker valve, but as the pressure of the drainage gases coalesce into the sealing member and increase said sealing.

[0051] FIG. 3 illustrates the modality in which the valve of the urinal consists of a valve of deformable elements consisting of springs 30, in a closed position showing the lines representing the flow of the gases 2. In this modality, to increase the seal surface between the tubular projection and the piston 31, so called by the movement within the tubular projection in the manner of a piston in a cylinder. In order to facilitate return to the closed position and to prevent the plunger from completely falling out, the plunger has a tapered configuration and a section which could be cylindrical where the lateral projections would be located to fix the ends of the springs, the opposing ends Are attached to the lateral projections of the lower tubular projection of the lower inner disc.

[0052] Somewhat further to guide the sealing plunger 31 towards the corresponding part of the tubular projection of the inner lower disk in its closed position the plunger carries at its distal end a rod 32. Again, the deformable elements do not require much pressure So that the plunger seals very strongly against the corresponding face of the tubular projection, it is sufficient that the deformable elements place the outer surface of the plunger in light contact with the corresponding surface of the tubular projection and the own pressure of the drainage gases will increase the contact force of the plunger and will result in a seal sufficient to prevent the exit of the drainage gases.

[0053] FIG. 4 illustrates the modality in which the urinal valve consists of a valve of deformable elements consisting of elastic bands 40, in a closed position, showing the lines representing the flow of the gases 2.

[0054] The elastic bands to be fixed on one side to the lateral projections of the tubular projection of the inner lower disk and on the other side to the lateral projections of the sealed piston, in one of its modality will consist of a hole with the edge reinforced in some way. This reinforcement could be an eye or a treatment of the edge of the hole.

[0055] To reduce the risk of these deformable elements separating from one of the two projections, there are various solutions such as deformation of the projections, such as a hook or even a flattening of the end in the manner of a rivet.

[0056] The conformation of the strips can be very diverse, having a conformation of round, triangular, rectangular, cross-sectional configuration, among others. The most efficient would be the round or square cross-section, with a bushing to attach a hook at its ends. A rectangular band would only employ a small longitudinal surface of the entire available area, so the thickness would have to be higher to reach the targets and much material would be wasted.

[0057] For issues regarding the sealing surface increase, it was chosen a 42 plunger with a tapered ending; with a zone of the tubular projection's internal walls below the disc. In its inferior endpoint 41 thickened in a tapered shape in a configuration that allows to accommodate the 42 plunger. As an additional detail, in order to guide the plunger to its closed position and avoid that it will completely get out, a 43 rod was added.

[0058] All of the other elements that integrate the valve's assembling they have already been mentioned in the description of the previous figures and we will only point the 40 lengthwise deformable band.

[0059] The FIG. 5 illustrated the association of the rocker's valve, with the sphere or little ball's valve in closed position, showing the lines that represents the gas flow.

[0060] As it may be appreciated, the difference between this figure and FIG. 1 only consists in the presence of the 50 little ball. This way it might be changed in the production process, the options of the valve with a little ball and the rocker or only the assemble of the rocker's valve, only by adding the little ball or sphere or not doing it.

[0061] Even though, as we previously stated the main body may be a single piece, for manufacturing and maintenance effects, within the figures of this description we are taking into consideration that the main body is formed by two telescopic cylinders, having the external cylinder, the bonds to the urinal and the hydraulic connection tube with the exit to the drain and the internal cylinder being shorter and including the superior adhered disc or constituting a part of the same thing and inlay the internal inferior disc with the superior shape in a very opened conic shape, and in the inferior shape the tubular projection for the rocker's valve setting.

[0062] FIG. 6 illustrate the association of the activation valve of deformable elements with the sphere or little ball valve in a closed position, showing the lines that represent the flow of gases.

[0063] FIG. 7 illustrates the modality of the sphere valve with rocker, and the sphere with deformable element and sphere, both in closed position.

[0064] The invention has been sufficiently described so that a person of ordinary skill in the art can to reproduce and obtain the results mentioned herein. However, any skillful person that in the field of art to which the present invention may be able to make modifications not described in this application, however, if required for the implementation of these changes in a process of free-lactose milk, it is required the matter claimed in the following claims, such systems must be within the scope of the invention.
