Description
SISTEMA PERFECCIONADO DE BLOQUEO ANTI FRAUDE PARA VÁLVULAS PERFECTED ANTI FRAUD LOCK SYSTEM FOR VALVES
OBJETO La presente invención, sistema perfeccionado de bloqueo anti fraude para válvulas, consiste en un novedoso y original sistema aplicable preferentemente para bloquear válvulas de suministro de fluidos, de manera que la válvula no pueda ser accionada por un tercero no autorizado a su manipulación. Por ello, este sistema será de especial interés para los proveedores de suministros de fluidos o de gases, como por ejemplo de agua y de gas natural, de manera que el proveedor pueda proceder a cortar un suministro cuando proceda, por ejemplo por impago del cliente, impidiendo que este pueda reabrir la válvula sin permiso del suministrador. Asimismo, será de utilidad para los propietarios de una instalación, por ejemplo el titular de una toma de agua en un puerto deportivo, impidiendo que terceros puedan hacer uso de su punto de suministro sin su permiso. OBJECT The present invention, an improved anti-fraud blocking system for valves, consists of a novel and original system preferably applicable for blocking fluid supply valves, so that the valve cannot be operated by a third party not authorized to handle it. Therefore, this system will be of special interest to suppliers of fluid or gas supplies, such as water and natural gas, so that the supplier can proceed to cut off a supply when appropriate, for example due to customer default. , preventing it from reopening the valve without permission from the supplier. It will also be useful for the owners of a facility, for example the owner of a water outlet in a marina, preventing third parties from using their supply point without their permission.
ANTECEDENTES: BACKGROUND:
El presente sistema tiene la finalidad específica denominada "anti fraude", consistente en evitar un uso fraudulento de las redes de distribución de fluidos y gases (agua, gas, etc .), en las que se requiere garantizar la inviolabilidad de las acometidas y puntos de suministro, que normalmente se encuentran dispersos en la proximidad de los puntos de consumo de cada cliente y por ello resultan de difícil vigilancia y control por parte del suministrador o proveedor del servicio. En la proximidad a dichos puntos de suministro se cuenta siempre con una válvula de corte de suministro. Estas pueden encontrarse agrupadas en determinadas dependencias, por ejemplo en un cuarto de contadores, donde el acceso sea relativamente restringido, pero en otras ocasiones dichas válvulas se encuentran en zonas de libre acceso en las que se dificulta mantener un control en lo que se refiere a la posible manipulación de dichas válvulas. This system has the specific purpose called "anti fraud", which consists in avoiding fraudulent use of fluid and gas distribution networks (water, gas, etc.), in which it is required to guarantee the inviolability of the connections and points of supply, which are normally dispersed in the vicinity of the points of consumption of each client and therefore are difficult to monitor and control by the supplier or service provider. In the proximity to these supply points there is always a supply shut-off valve. These can be grouped in certain units, for example in a meter room, where access is relatively restricted, but on other occasions these valves are in areas of free access where it is difficult to maintain control in regard to the possible manipulation of said valves.
Así, en aquellas situaciones en las que el proveedor deba cortar un suministro, por ejemplo por impago o por determinadas razones de seguridad, normalmente se procede a instalar un precinto sobre la llave de la válvula de corte, de manera que quede evidenciada toda posible manipulación posterior. Sin embargo, eso no implica poder determinar quién ha podido violar un precinto, por lo que esta cuestión genera frecuentes problemas a los proveedores frente
a determinados clientes que sistemáticamente manipulan las válvulas de corte para recuperar el servicio cortado, ocasionando importantes pérdidas al proveedor. En tales casos la única solución que se le plantea al proveedor es proceder a desmantelar parte de la instalación de manera que se dificulte la recuperación del servicio sin autorización, por ejemplo, desmontando parte de la conducción o la propia válvula, en lugar de precintarla. Evidentemente el coste de desmantelamiento y posterior reanudación del servicio se eleva, puesto que se requiere realizar complejos trabajos de instalación en lugar de manipular una válvula, lo que hace que esta solución no sea la preferida por los proveedores de suministros de fluidos y sustancias gaseosas. Thus, in those situations in which the supplier must cut off a supply, for example for non-payment or for certain safety reasons, a seal is normally installed on the key of the shut-off valve, so that all possible manipulation is evidenced later. However, that does not imply being able to determine who has been able to violate a seal, so this issue generates frequent problems for suppliers in the face of to certain customers who systematically manipulate the shut-off valves to recover the cut service, causing significant losses to the supplier. In such cases, the only solution that is proposed to the supplier is to proceed to dismantle part of the installation so that it is difficult to recover the service without authorization, for example, by dismantling part of the pipeline or the valve itself, instead of sealing it. Obviously the cost of dismantling and subsequent resumption of service is high, since complex installation work is required instead of manipulating a valve, which makes this solution not preferred by suppliers of supplies of fluids and gaseous substances.
Una solución alternativa, puede ser el empleo de válvulas especiales, que no pueden ser accionadas si no se utiliza una herramienta especial, de la cual dispone exclusivamente el personal autorizado de la empresa distribuidora o suministradora. Así, el Modelo de Utilidad español número 214.390 denominado "Dispositivo perfeccionado para enclavamiento de válvulas" de D. José Púa Bernal, de 18.10.1976 ya describe una válvula de seguridad que mediante el enclavamiento de un volante provisto en la llave de apertura y cierre, consigue bloquear la manipulación de la misma. Por otra parte, se puede citar el Modelo de Utilidad español número 258.127 de 07.05.1981 denominado "Válvula bajo cerradura para corte de suministros de líquidos y gases", solicitado por D. Eduardo Arteaga Velasco, que describe una válvula que permite el corte de suministro de cualquier fluido o gas que cuenta con un pivote de accionamiento susceptible de ser bloqueado por un mecanismo de cerradura que actúa sobre una membrana interior de la válvula impidiendo el paso del referido suministro. An alternative solution may be the use of special valves, which cannot be operated if a special tool is not used, which is exclusively available to the authorized personnel of the distribution or supply company. Thus, the Spanish Utility Model number 214.390 called "Improved device for interlocking valves" of Mr. José Púa Bernal, of 18.10.1976 already describes a safety valve that by interlocking a steering wheel provided in the opening and closing key , manages to block the manipulation of it. On the other hand, we can mention the Spanish Utility Model number 258.127 of 07.05.1981 called "Valve under lock for cutting supplies of liquids and gases", requested by Mr. Eduardo Arteaga Velasco, which describes a valve that allows the cutting of supply of any fluid or gas that has a drive pivot that can be blocked by a lock mechanism that acts on an inner membrane of the valve preventing the passage of said supply.
La presente invención representa un avance respecto a los sistemas y mecanismos conocidos para bloquear válvulas de suministro y por ello, la supone una novedosa solución y un avance respecto a los sistemas conocidos en el Estado de la Técnica. The present invention represents an advance with respect to the known systems and mechanisms for blocking supply valves and therefore, it is a novel solution and an advance with respect to the systems known in the prior art.
DESCRIPCION DESCRIPTION
La invención que constituye el objeto de esta patente y que se describe a continuación, responde a las necesidades antes aludidas, relativas a garantizar el bloqueo de un suministro. Este sistema comprende un mecanismo de bloqueo para una válvula, consistente en una cubierta que sustituye a la manilla de la válvula y que para su
accionamiento se requiere el empleo de una herramienta especial, estando además configurada su estructura de forma que resulte inaccesible la tuerca de seguridad que fija el referido dispositivo de bloqueo, así como la protección de los puntos de fijación del sistema o topes, para evitar la apertura de la válvula, resultando de esta manera imposible violar este sistema de bloqueo. The invention that is the subject of this patent and described below, responds to the aforementioned needs, relative to guarantee the blocking of a supply. This system comprises a locking mechanism for a valve, consisting of a cover that replaces the valve handle and for its The use of a special tool is required, and its structure is also configured so that the safety nut that fixes the said locking device is inaccessible, as well as the protection of the system fixing points or stops, to avoid opening of the valve, thus rendering it impossible to violate this blocking system.
Así, el presente sistema perfeccionado de bloqueo anti-fraude para válvulas se encuentra constituido por un sistema ideado para poder bloquear una válvula que dispone en su superficie exterior de una zona de un cuello de asiento de su llave de accionamiento, siendo este cuello de forma normalmente cilindrica y perpendicular al eje longitudinal entre la boca de entrada y salida de la válvula Thus, the present improved anti-fraud blocking system for valves is constituted by a system designed to be able to block a valve that has on its outer surface an area of a seat neck of its actuation key, this neck being shaped normally cylindrical and perpendicular to the longitudinal axis between the inlet and outlet of the valve
Este sistema es válido para válvulas en las que su llave puede encontrarse constituida por un mando de accionamiento, que puede ser de cualquier forma conocida (palanca, mariposa, cuadradillo, etc ..) y cuyo movimiento queda limitado por una serie de topes de accionamiento. This system is valid for valves in which its key can be constituted by a drive control, which can be of any known shape (lever, butterfly, square, etc.) and whose movement is limited by a series of actuation stops .
Así, los topes delimitan el movimiento del mando de válvula en su operativa normal de apertura o cierre, pero se puede contar con ellos también para el bloqueo del movimiento de la cubierta o capuchón con la que se cubre el mecanismo de accionamiento de la válvula, impidiendo abrir la llave haciendo girar la cubierta o capuchón como si se tratara de una llave. Thus, the stops delimit the movement of the valve control in its normal opening or closing operation, but they can also be counted on for blocking the movement of the cover or cap with which the valve actuation mechanism is covered, preventing the key from being opened by turning the cover or cap as if it were a key.
Dicho capuchón se encuentra a su vez, formado por una cubierta de forma cilindrica o troncocónica disponiendo de medios mecánicos para fijarse al vástago de accionamiento de la válvula, en el asiento del vástago donde se fija el mando o llave, normalmente mediante una tuerca de seguridad Said cap is in turn formed by a cylindrical or truncated conical cover having mechanical means to be fixed to the valve actuation stem, in the stem seat where the control or key is fixed, usually by means of a lock nut
La referida tuerca de seguridad debe ser ligeramente inferior al diámetro interior de la cavidad del extremo del capuchón de manera que se pueda introducir entre ambas una llave o herramienta para permitir el accionamiento de la tuerca. Said safety nut must be slightly smaller than the inside diameter of the end cavity of the cap so that a wrench or tool can be inserted between them to allow the nut to drive.
Asimismo, en el extremo de mayor diámetro del capuchón, que cubre el mecanismo de accionamiento de la válvula, se puede disponer de un resalte interno de manera que una vez colocado sobre la válvula, encaje entre los topes salientes de la válvula para bloquear está en la posición de cerrado, imposibilitando el accionamiento del vástago de la válvula.
A su vez, la tuerca de seguridad para la fijación de dicho capuchón al vástago de la válvula, tiene forma de tapón cilindrico abierto por un extremo con una rosca interior que se rosca al extremo del asiento del vástago de la válvula. Para su accionamiento, esta tuerca finaliza en el extremo opuesto en una cara plana, en cuyo centro se encuentra un resalte de forma irregular para poder encajar y ser accionado por una llave de tubo hembra, o un bajo relieve, para poder encajar y ser accionado en este caso por una llave de tubo macho, cuyo perfil no debe corresponder con ninguna configuración o figura estándar de llave existente en el mercado. De esta manera, dicho tapón rosca, que es la tuerca de seguridad, puede ser accionado únicamente con una llave de tubo (hembra o macho) del mismo perfil, que no es accesible al público en general y de la que dispone únicamente el titular de la instalación, que puede desbloquear el sistema de seguridad desenroscando el tapón rosca que es dicha tuerca de seguridad. Likewise, at the larger diameter end of the cap, which covers the valve actuation mechanism, an internal projection can be arranged so that once placed on the valve, it fits between the protruding stops of the valve to block is in the closed position, making it impossible to operate the valve stem. In turn, the lock nut for fixing said cap to the valve stem is in the form of a cylindrical cap open at one end with an internal thread that is threaded to the end of the valve stem seat. For its operation, this nut ends at the opposite end on a flat face, in whose center there is an irregularly shaped projection to fit and be operated by a female socket wrench, or a low relief, to fit and be operated in this case by a male tube wrench, whose profile must not correspond to any configuration or standard figure of wrench existing in the market. In this way, said screw cap, which is the safety nut, can only be operated with a socket wrench (female or male) of the same profile, which is not accessible to the general public and which only the holder of the installation, which can unlock the safety system by unscrewing the screw cap which is said safety nut.
Por todo esto, para proceder al bloqueo de una válvula de suministro, el titular de la instalación acudirá con la llave de tubo especial, antes descrita, y procederá en primer lugar a cerrar la válvula accionando el mando que esta tiene originalmente (ya sea con forma de palanca, mariposa, cuadradillo o la que corresponda). Una vez cerrada, se desmontará este mando, y se acoplará el capuchón, haciendo que la patilla formada por el referido resalte interno de este quede encajada entre los dos topes paralelos del cuello de la válvula. A continuación se rosca la tuerca de seguridad For all this, to proceed with the blockage of a supply valve, the owner of the installation will come with the special tube wrench, described above, and will first proceed to close the valve by operating the control that it originally has (either with lever, butterfly, square or corresponding shape). Once closed, this control will be disassembled, and the cap will be attached, causing the pin formed by the said internal protrusion of this one to fit between the two parallel stops of the valve neck. Then the lock nut is threaded
Como únicamente los operarios de la compañía suministradora disponen de la llave especial, el usuario no será capaz de volver a abrir la válvula, quedando así cortado el suministro. Since only the operators of the supply company have the special key, the user will not be able to reopen the valve, thus cutting off the supply.
Asimismo, el sistema puede contar además con un tapón de inaccesibilidad, de forma cilindrica hueco y abierto por uno de sus extremos, que actúa como revestimiento de protección externo de la tuerca de seguridad. Dicho tapón encaja a presión en el interior cilindrico del capuchón de bloqueo, impidiendo el acceso directo a la tuerca de bloqueo que hace de tuerca de seguridad, no siendo posible su extracción solo con las manos. Likewise, the system can also have an inaccessible plug, hollow and open in a cylindrical shape at one of its ends, which acts as an external protective covering of the lock nut. Said cap snapped into the cylindrical interior of the locking cap, preventing direct access to the locking nut that acts as a lock nut, and its removal is not possible only with the hands.
Dicho tapón protector, este oculta la tuerca de seguridad, haciendo menos evidente su existencia y evitando un posible intento de manipulación por parte del usuario, aunque no cuente con una llave especial. Asimismo, sirve para evitar la entrada de suciedad.
Por otra parte y para mayor seguridad, el referido capuchón incorpora un taladro transversal situado próximo a su extremo más alejado del eje longitudinal entre la boca de entrada y salida de la válvula, por donde se puede pasar y colocar un candado de seguridad impidiendo el acceso a la tuerca de seguridad con forma de tapón rosca, no pudiendo ser desenroscado aunque se dispusiera de la llave herramienta especial de manipulación. Said protective cap, this hides the safety nut, making its existence less evident and avoiding a possible attempt of manipulation by the user, although it does not have a special key. It also serves to prevent dirt from entering. On the other hand and for greater security, the aforementioned cap incorporates a transverse bore located near its end furthest from the longitudinal axis between the inlet and outlet of the valve, through which a safety lock can be passed and placed preventing access to the nut with the form of a screw cap, it cannot be unscrewed even if the special handling tool wrench was available.
Finalmente, el sistema se completa con la referida herramienta especial para el bloqueo o desbloqueo de la tuerca de seguridad. Esta herramienta es una llave hembra o macho de tubo con la misma forma de perfil, del resalte o del bajo relieve, que el definido en la cara exterior de la tuerca de seguridad descrita más arriba, pero al contrario que ésta en bajo relieve o en resalte, para poder encajar entre ambas pudiendo la herramienta especial accionar la tuerca de seguridad. Esta llave es de forma preferentemente cilindrica y de dimensiones lo suficientemente estrecha y de suficiente longitud para poder entrar con holgura en el interior cilindrico del capuchón, accediendo a la tuerca de seguridad. Finally, the system is completed with the aforementioned special tool for locking or unlocking the lock nut. This tool is a female or male socket wrench with the same profile, protrusion or low relief shape, as defined on the outer face of the lock nut described above, but unlike in low relief or highlight, in order to fit between them, the special tool can actuate the lock nut. This key is preferably cylindrical in shape and of sufficiently narrow dimensions and of sufficient length to be able to easily enter the cylindrical interior of the cap, accessing the lock nut.
Por otra parte, dicha llave o herramienta especial, acaba en el extremo opuesto al útil descrito, en forma de mango para facilitar su giro, por eso preferiblemente el mango será de forma en T, pudiendo ser de otras formas también. On the other hand, said special tool or wrench ends at the opposite end to the described tool, in the form of a handle to facilitate its rotation, that is why preferably the handle will be T-shaped, and it may also be in other ways.

In this case said stops are constituted by protruding appendages of said neck (2), two of them (3) and (4) being tangential thereto and arranged at 90 e , while a third stop (5) is transverse to the neck and parallel to the stop (3).
En este caso, los referidos topes salientes (3) y (4) delimitan el movimiento del mando de la válvula en su operativa normal de apertura o cierre, mientras que el tope saliente (5) se ha ideado para ser utilizado con el tope (4) para la operación de bloqueo de la válvula. In this case, the said protruding stops (3) and (4) delimit the movement of the valve control in its normal opening or closing operation, while the protruding stop (5) is designed to be used with the stop ( 4) for the valve blocking operation.
Para el bloqueo de la válvula, se retira la llave, aquí no representada, que iría sujeta al extremo del vástago (6) de accionamiento de la válvula, en una zona de asiento (7) de sección rectangular, por una tuerca. To lock the valve, the key, not shown here, which would be attached to the end of the valve actuating rod (6), in a seating area (7) of rectangular section, is removed by a nut.
Posteriormente se cubre y protege la zona de accionamiento de la válvula antes descrita constituida por el cuello (2) del asiento y los topes salientes (3, 4 y 5) mediante un capuchón (8) de protección que constituye el sistema de protección. Dicho capuchón (8) se encuentra formado por una cubierta de forma cilindrica constituida en dos tramos cilindricos (9 y 10) de diámetro decreciente, a medida que nos alejamos del eje longitudinal entre la boca de entrada y salida de la válvula, conectados por un tramo intermedio troncocónico (1 1 ), estando interiormente separados ambos tramos cilindricos por un plano interno (12) transversal, provisto de un orificio interno (13), de forma rectangular
donde encaja y por donde pasa el extremo del vástago (6) que adopta una sección rectangular de la misma sección que el referido orificio (13), pudiendo fijarse el capuchón al vástago por mediación de una tuerca de seguridad (17), que penetrando por la cavidad interior cilindrica del extremo del capuchón (14) es roscada en la zona de asiento (7) del extremo del vástago (6) de accionamiento de la válvula. Subsequently, the actuation zone of the valve described above is constituted and protected, consisting of the neck (2) of the seat and the projecting stops (3, 4 and 5) by means of a protective cap (8) that constitutes the protection system. Said cap (8) is formed by a cylindrical cover consisting of two cylindrical sections (9 and 10) of decreasing diameter, as we move away from the longitudinal axis between the inlet and outlet of the valve, connected by a Intermediate trunk section (1 1), both cylindrical sections being internally separated by a transverse internal plane (12), provided with an internal hole (13), rectangular in shape where it fits and where the rod end (6) passes which adopts a rectangular section of the same section as the aforementioned hole (13), the cap can be fixed to the rod by means of a lock nut (17), which penetrating through the cylindrical inner cavity of the end of the cap (14) is threaded into the seating area (7) of the end of the valve actuator stem (6).
Para ello, el diámetro exterior de la tuerca de seguridad (17) debe ser ligeramente inferior al diámetro interior de la cavidad cilindrica (14) del extremo del capuchón de manera que sin existir roce entre dichas superficies, se pueda introducir entre ambas una llave o herramienta, de la longitud suficiente para alcanzar la tuerca y permitir el accionamiento de la misma. For this, the outer diameter of the lock nut (17) must be slightly smaller than the inside diameter of the cylindrical cavity (14) of the end of the cap so that without existing friction between said surfaces, a wrench or tool, of sufficient length to reach the nut and allow its actuation.
Por otra parte, en el extremo de mayor diámetro del capuchón (8) se puede disponer de un resalte interno (16), de manera que una vez colocado sobre la válvula, encaje entre los topes salientes (4) y (5) de la válvula (1 ), cuando se desea bloquear la válvula en la posición de cerrado, imposibilitando el accionamiento del vástago (6) de la válvula, que mueve el obturador interior que cierra el paso del fluido por su interior. On the other hand, at the larger diameter end of the cap (8) an internal projection (16) can be arranged, so that once placed on the valve, it fits between the projecting stops (4) and (5) of the valve (1), when it is desired to lock the valve in the closed position, preventing the actuation of the valve stem (6), which moves the inner plug that closes the passage of the fluid inside.
Asimismo, la referida tuerca de seguridad (17) para la fijación de dicho capuchón (8) al vástago (6) de la válvula (1 ), tiene forma de tapón cilindrico abierto por un extremo con una rosca interior (20) que se rosca al extremo del asiento (7) del vástago (6) de la válvula, mientras que por el extremo opuesto finaliza en una cara plana (19), en cuyo centro se encuentra un resalte de forma irregular (18) con la formado de un determinado perfil coincidente con el de una llave de tubo hembra de características especiales, como es la herramienta especial (22), con la que encaja y que no corresponde a ninguna configuración o figura estándar de llave existente en el mercado. De esta manera, dicho tapón rosca que es la tuerca de seguridad (17) puede ser es accionado únicamente con la llave citada de un perfil coincidente, que no es accesible al público en general, pudiendo únicamente el titular de la instalación desbloquear el sistema de seguridad desenroscando el tapón rosca que es la tuerca de seguridad (17). Likewise, said safety nut (17) for fixing said cap (8) to the stem (6) of the valve (1), has the form of a cylindrical cap open at one end with an internal thread (20) that is threaded at the end of the seat (7) of the valve stem (6), while at the opposite end it ends on a flat face (19), in whose center there is an irregularly shaped shoulder (18) with the shape of a certain profile coinciding with that of a female socket wrench with special characteristics, such as the special tool (22), with which it fits and that does not correspond to any configuration or standard figure of the existing wrench in the market. In this way, said screw cap which is the lock nut (17) can be operated only with the key mentioned of a matching profile, which is not accessible to the general public, and only the installation holder can unlock the system safety by unscrewing the screw cap which is the lock nut (17).
Asimismo, el sistema puede contar además con un tapón (21 ) de inaccesibilidad, de forma cilindrica hueca y abierta por uno de sus extremos, que actúa como revestimiento de protección externo de la tuerca de seguridad (17). Dicho tapón (21 ) encaja a presión en el interior cilindrico (14) del capuchón (8) de bloqueo, impidiendo el acceso directo a la tuerca de bloqueo que es la tuerca de seguridad (17), no siendo posible su extracción solo con las
manos. Este tapón oculta la tuerca de seguridad, haciendo menos evidente su existencia y evitando un posible intento de manipulación, a la vez que sirve para evitar la entrada de suciedad. Por otra parte y para mayor seguridad, el referido capuchón (8) incorpora un taladro transversal (15) situado próximo a su extremo más alejado del eje longitudinal entre la boca de entrada y salida de la válvula por donde se puede pasar y colocar un candado de seguridad impidiendo el acceso a la tuerca de seguridad (17) aun eliminando el tapón (21 ). Finalmente, el sistema se completa con la referida herramienta especial (22) para el bloqueo o desbloqueo de la tuerca de seguridad (1 7). Esta herramienta es una llave hembra de tubo con la misma forma de perfil (23) que el definido en la cara exterior de la tuerca de seguridad (1 7) descrita más arriba. Esta llave es de forma preferentemente cilindrica y de dimensiones lo suficientemente estrecha para poder entrar con holgura en el interior cilindrico del capuchón (8), accediendo a la tuerca de seguridad (17). En uno de sus extremos acaba en una cara plana donde define la referida forma de perfil (23) entrante similar a la forma saliente de la cara de la de la tuerca de seguridad (17), de manera que ambas piezas pueden acoplarse, pudiendo la herramienta especial (22) accionar la tuerca de seguridad (17). Likewise, the system can also have a plug (21) that is inaccessible, with a hollow cylindrical shape and open at one of its ends, which acts as an external protective covering for the lock nut (17). Said plug (21) snap into the cylindrical interior (14) of the locking cap (8), preventing direct access to the locking nut that is the lock nut (17), its removal not only possible with the hands. This plug hides the safety nut, making its existence less evident and avoiding a possible attempt at manipulation, while serving to prevent dirt from entering. On the other hand and for greater security, the aforementioned cap (8) incorporates a transverse bore (15) located near its end furthest from the longitudinal axis between the inlet and outlet of the valve through which a padlock can be passed and placed safety guard preventing access to the lock nut (17) even removing the cap (21). Finally, the system is completed with the aforementioned special tool (22) for locking or unlocking the lock nut (1 7). This tool is a female socket wrench with the same profile shape (23) as defined on the outer face of the lock nut (1 7) described above. This key is preferably cylindrical and narrow enough in size to be able to easily enter the cylindrical interior of the cap (8), accessing the lock nut (17). At one of its ends it ends in a flat face where it defines the aforementioned profile profile (23) similar to the protruding shape of the face of the lock nut (17), so that both pieces can be coupled, and the special tool (22) actuate the lock nut (17).
Por otra parte, dicha llave o herramienta especial (22), presenta en el extremo opuesto un taladro pasante y perpendicular a su eje que permite el acoplamiento de un pasador (24) fijado con una anilla en un extremo y un remache en el opuesto cuya misión consiste en facilitar el accionamiento manual de la herramienta especial (22) actuando como palanca, a modo de llave en T.
On the other hand, said key or special tool (22), has at its opposite end a through hole and perpendicular to its axis that allows the coupling of a pin (24) fixed with a ring at one end and a rivet at the opposite whose mission is to facilitate the manual operation of the special tool (22) acting as a lever, as a T-key.
