    SPRAYER FOR IRRIGATION NETWORKS WITH PERMANENT PRESSURE
    D E S C R I P C I O N
    OBJECT OF THE INVENTION
    The present invention relates to a sprinkler, and specifically to a sprinkler for irrigation networks with permanent pressure, for example of the type existing in some golf courses.
    BACKGROUND OF THE INVENTION
    Irrigation of large surfaces, such as a golf course, is often fed through water networks with continuous pressure on a sprinkler or a net under load, unlike for example the irrigation of gardens or other small areas. This is because it seeks to minimize the number of sprinklers, and they must cover large areas, so that sufficient water pressure is needed.
    The sprinklers used in this type of irrigation comprise a body with a connection to the network, at least, a spray nozzle of the environment with water coming from said network and an electric or hydraulic valve for external control, so that it can be opened and remotely close the irrigation fed from the network under pressure through the electric or hydraulic valve.
    They also include other elements, such as telescopic rods from the sprinkler body, where nozzles, filters, turbines, recoil springs, etc., are implemented, but which do not affect the present invention.
    The disadvantage of these sprinklers is that the valve controls a foot valve at the base of the sprinkler which is the one that allows the closure, and if in any case this foot valve fails for some reason it is necessary to cut the supply network with the consequent loss of water and time that entails.

    DESCRIPTION OF THE INVENTION
    The sprinkler of the invention has a configuration that solves the problem described, since it implements means that allow to cut the water of the supply network in case of failure of the electric or hydraulic or standing valve. It also has a simple configuration that even allows the adaptation of existing sprinklers. Indicate that the sprinkler can be of any size.
    The sprinkler is therefore of the type comprising a body with a connection to the network with pressure, at least, a spray nozzle of the environment with water from said network, and an electric or hydraulic valve for external control. You can also have other elements (telescopic rod for sprinklers, recoil springs, filters, turbines, etc.).
    With this configuration, according to the invention, the sprinkler comprises an additional cutting key in connection with the network, said cutting key comprising a control accessible from the views of the sprinkler.
    The accessible control allows the sprinkler cutting key to be operated without having to dig it up, which would not be very useful and would eventually deteriorate the key itself with moisture. In this way, in addition, it is possible to manipulate, clean or replace the sprinkler's foot valve without the need to cut the water from the irrigation circuit with the consequent loss of time and water.

    PREFERRED EMBODIMENT OF THE INVENTION
    The sprinkler (1) for irrigation networks (2) with permanent pressure of the invention comprises in this example (see figs. 1 and 3) a body (3) with a connection (4) to the network (2), at least, a nozzle (5) for spraying the environment -implemented in a telescopic rod (5a) in these examples- with water from said network (2) and an electric valve, not shown, with its plug (7) for electric control, being able to implement other elements not represented, such as spring return springs (5a), filters, turbines, etc.
    According to the invention, it is provided that the sprinkler (1) comprises an additional cutting key (8) in the connection (4) with the network (2), said cutting key (8) also comprising an accessible control (9) from the exposed parts of the sprinkler (1), such as the upper cover (3a) of the sprinkler (1) or of the rod (5a).
    The cutting key (8) can be integrated in the body (3) the sprinkler (1), or the sprinkler (1) can be attached to the body (3) through removable means, such as threads of various types (BSP, ACME, or any other). This last feature allows reconfiguring the existing sprinklers to sprinklers (1) of the invention, and is the variant shown in the figures, where the thread coupling (30) of the key (8) to the connection (4) is appreciated with the network (2) of the body (3) of the valve (1). The integrated configuration would be of application in sprinklers (1) new, with better manufacturing costs.
    The control (9) can comprise a deflection (10) of rotating rods (11). This variant is shown in Figures 1 and 2, where specifically in Figure 1 it can be seen that the offset (10) comprises intermediate cardan joints (12), and that the rods (11) and / or joints (12) comprise a cover (16) of protection against moisture, while in figure 2 it can be seen as the upper end (19) of the deflection (10)

    It is accessible on the cover (3a) of the body (3) of the sprinkler (1), and comprises drive machining (15) by means of a tool (specifically in the figure it would be an Allen key, which can obviously be of other configurations: star, plane etc). In addition, it is provided that said upper end (19) of the deflection (10) comprises markings (22) of signaling the open or closed position of the key (8).
    Another variant is shown in Figure 3, where the control (9) comprises a mobile cable (17) disposed inside a fixed sealed sheath (18), opened superiorly by the cover (3a) of the body (3) of the sprinkler (1) and inferiorly in a receptacle (24) for connection with the key (8), the cable (17) comprising an upper handle (28) integrated in a cap (20) of the sheath (18) (see detail of the Figure 4), and a lower hitch (21) for connection with the key (8). In this way, pulling the handle (28) simultaneously pulls the cable (17), and through the lower hitch (21) activates the key (8), the plug (20) being closed to close the sheath (18) superiorly preventing the entry of moisture. Both this plug (20) and the upper end (19) of the deflection of the previous variant comprise seals or seals, not shown, which prevent moisture from entering the sheath (18) and the cover (3a) achieving a Low maintenance operation.
    Finally, indicate that the key (8) is preferably made of plastic materials, to minimize corrosion.
    Describing sufficiently the nature of the invention, it is indicated that the description thereof and of its preferred embodiment should be interpreted in a non-limiting manner, and that it encompasses all possible embodiments that are deduced from the content of the present specification. and of the claims.
