Description

Sprinkler device, water flow regulator-reducer applicable to taps and hoses.

This utility model refers to a device to disperse, regulate and reduce water flow emerging in taps and hoses, its purpose being to facilitate water consumption savings; based on the fact that there is a relationship between the outflow through this object of the invention, and the rotation of its outer body, such as It is represented in the graph of figure 6, attached hereto description. This spinning action of your outer body releases or throttles the flow of water.

Due to its own design, in maximum position opening results in a maximum flow rate lower than the supply in the network, being the own reduction of each design (in the example attached reduces 40% of the network flow). The characteristics Associates will be described later.

In the applications of this model of utility associated with the use of faucets (domestic, hospitality and similar), the maximum opening of the device does not result in a dispersed water outlet that causes inconvenience or inconvenience some, just a slight turn of the outer body to move from a null or minimal flow, to another of habitual use. Therefore, it is not it is necessary to modify this position when handling the tap, unless decide to limit the flow rate before use to another value required. In this way the water consumption is reduced. He device allows use with hot water from the Different known heaters.

In the applications associated with the use of hoses, such as the domestic case, gardening, land of cultivation, gives rise to a greater dispersion of water, since in This application, the device has fewer holes outlet than in the case of faucets, thus allowing water reach, the lower layers of the land, with obvious savings in its consumption, avoiding the traditional "flood" of land to achieve the same end.

It is therefore evident that the present model of utility, offers a practical and effective application in your utilization, attending sufficiently all the above aforementioned.

In order to carry out a Detailed description of the device referred to, it attached some drawings in which, by way of non-limiting example, a practical embodiment of the aforementioned has been represented device.

In these drawings,

Figure 1 is a sectional view of the body Of the device;

Figure 2 is a view, also sectioned, of the device core;

Figure 2bis is a detail in plan, and sectioned by AA of the core, showing the plans for the tightening tool;

Figure 3 is a sectional view of the device dispersing nozzle;

Figure 4 draws the device in section mounted, with the core located inside the body, and in the open position;

Figure 5 complements the previous figure, showing the device closed;

Figure 6 is a graph where it has been drawn over coordinates the relationship between flows and aperture of device, corresponding to a case study, will be considered as mode of example, and that, when generalizing, allows to have a behavioral reference, qualitatively but not quantitative, because each design will have its curve associated particular.

According to the drawings outlined, the device consists of the body (1), hollow inwardly, and by the sliding core (2), similar to a plunger, inside the body (1), the diameter of the core (2) slightly smaller than the inside diameter of the body (one). Which has a knurled area on its outer surface (1a) that facilitates grip.

The body (1) has in its front part a threaded area (3), of smaller diameter, on which it will be fixed, properly threaded, the diffuser nozzle (4), being located a O-ring (5), as a seal, on the part rear of that front threaded area (3), between the body and the flat back face of the diffuser nozzle (4).

This diffuser nozzle (4), cylindrical and internally threaded to be able to be fixed at the end (3) of the body (1), has a series of holes on its front face (4a) (6) that cause water to flow in small unit threads and parallel, and not in the form of a single jet, and therefore, this nozzle (4) has this dispersing effect.

The inside of this front face (4a) is slightly convex, in order to carry out a better water flow distribution to all holes (6) of this front face (4a) of the diffuser nozzle (4).

For the application of the device in hoses, the diffuser nozzle (4) will be equipped with fewer holes (6), with the purpose of producing a greater dispersion of water, allowing so that it reaches the lower layers of the ground, decreasing water consumption for garden irrigation, crops or the like.

The core (2) of the device is also hollow (7), presenting at its end a narrowing (2a), after a inclined plane, narrowing in which the holes (7a) that communicate the inside of the core (2), where the water comes from the tap or hose to which it is connected The device with the inside of the body.

Through these holes (7a), water passes through flood the front end part (8a) of this cylindrical cavity (8) of the body (1).

An O-ring (9), located in the area core core (2), guarantees the tightness of the interior (8) of the body, towards the rear threaded area (10) of the inside of the body (1).

The core (2) has in its back two threaded zones: A first zone (11), located before the end rear, which will thread on the rear threaded area (10) of the body (1), which thread will allow to give the movement manually circulate the body (1) over the core (2), to carry out the opening or closing action of the device.

And a second threaded zone (12), male or female, located at the rear end of the core (2) where it will be fixed the tap mouth (13) in which the device is placed, or the corner at the end of the irrigation hose to which, also, The device described must be placed.

The circular movement of the body (1) on the core (2), as indicated in previous paragraphs, is the one that causes the displacement, in axial direction, of the core (2) with with respect to the body (1) so that the conical end (2a) of the mentioned core (2), when approaching the opening (14a) of the final duct (14) of the body (1), smaller in diameter than the part front (8a) of the recess (8) where the core moves, will get to close the step, while separating, unscrewing in the opposite direction, the passage of the water flow will open which, to through the final duct (14) it will reach the diffuser nozzle (4).

The turn that will be given to the body (1) on the core (2) to regulate the flow, is limited by the pivot cylindrical (15), housed in the rear face (1a) of the body (1), which will meet the pivot (16), protruding from the face (2b), of the core (2). This pivot (16), threaded in said place, is the one will stop the rotation of the body by retaining the cylindrical pivot (15), the  which remains constantly pressed against the face (2b) of the core (2) by the action of the spring (17), located inside Your own accommodation.

As seen in Figure 6, through the opening of the device represented on the axis of the abscissa from C (closed) to MA (maximum opening), the flow rate obtained, represented on the axis of the ordinates (Q), it can be regulated up to a fraction of the total (Q_ {RED}) with the maximum opening of the device, all with the consequent saving of water that will result. Both the maximum turning position and the reduction (with respect to Q_ {RED}) of associated flow, depend on the design of Each particular application.

Describe the characteristics sufficiently basic of the device object of this utility model, it indicates that all variation in dimensions, shapes, exterior finish and types of materials used in the practical realization of device, will not alter the essentiality of it, leaving this summarized in the following claims.
