DESCRIPCIÓN DESCRIPTION
VÁLVULA DE SEGURIDAD PARA DEPÓSITOS DE COMBUSTIBLE.SAFETY VALVE FOR FUEL TANKS.
Objeto de Ia invenciónObject of the invention
La presente invención se refiere a una válvula de seguridad para depósitos de combustible, especialmente aplicable a depósitos de vehículos de gasóleo, con el fin de evitar el llenado del depósito con gasolina.The present invention relates to a safety valve for fuel tanks, especially applicable to diesel fuel tanks, in order to avoid filling the tank with gasoline.
Antecedentes de Ia invención.Background of the invention.
Las estaciones de servicio dedicadas al suministro de carburante para vehículos disponen de surtidores específicos de gasolina y de gasóleo, siendo el usuario del vehículo el que elige el tipo de carburante a utilizar.Service stations dedicated to the supply of fuel for vehicles have specific suppliers of gasoline and diesel, the user of the vehicle choosing the type of fuel to be used.
El problema que se plantea, principalmente en el caso de los conductores noveles y de usuarios de vehículos de alquiler, es el riesgo de equivocación a Ia hora de elegir el tipo de carburante, gasolina o gasóleo, ya que cuando se añade gasolina en un depósito de gasóleo, o cuando se añade gasóleo en un depósito de gasolina se produce una situación de riesgo, dado que el uso del combustible indebido puede acarrear averías considerables del motor y sus partes mecánicas, además de una costosa reparación que requiere el vaciado del combustible y Ia limpieza de las canalizaciones, bombas de presión, filtros, inyectores y otras piezas del sistema de alimentación.The problem that arises, mainly in the case of novice drivers and users of rental vehicles, is the risk of error when choosing the type of fuel, gasoline or diesel, since when gasoline is added to a tank of diesel, or when diesel is added to a fuel tank, a risk situation occurs, since the use of improper fuel can lead to considerable damage to the engine and its mechanical parts, in addition to an expensive repair that requires the emptying of the fuel and The cleaning of the pipes, pressure pumps, filters, injectors and other parts of the feeding system.
Así, las mangueras de los surtidores están dotadas de unos boquereles, de diferente diámetro para Ia gasolina y para el gasóleo, y a su vez las bocas de entrada de los depósitos de combustible están dimensionadas de acorde a estos diámetros. De esta forma no es posible echar gasóleo en un depósito de gasolina, porque el diámetro del boquerel correspondiente es sensiblemente mayor y no entra.Thus, the hoses of the jets are provided with nozzles, of different diameter for the gasoline and for the diesel, and in turn the inlets of the fuel tanks are sized according to these diameters. In this way it is not possible to put diesel in a gas tank, because the diameter of the corresponding nozzle is significantly larger and does not enter.
Sin embargo si es posible echar gasolina en un depósito de gasóleo, por Io que sigue existiendo el citado riesgo para los vehículos cuyos motores consumen gasóleo.However, it is possible to add gasoline to a diesel tank, so there is still the aforementioned risk for vehicles whose engines consume diesel.
Descripción de Ia invenciónDescription of the invention
La válvula de seguridad para depósitos de combustible, objeto de esta invención, está diseñada para evitar que se llene con gasolina un depósito de un vehículo de gasóleo, ya sea de forma accidental o por negligencia, bastando para ello con colocar dicha válvula en el conducto o boca de entrada del depósito.The safety valve for fuel tanks, object of this invention, is designed to prevent a tank of a diesel vehicle from being filled with gasoline, either accidentally or negligently, being sufficient for this. with placing said valve in the duct or inlet port of the tank.
La válvula comprende un cuerpo tubular, abierto por sus extremos, y destinado a posicionarse de forma ajustada en el interior de Ia boca del depósito de combustible; definiendo dicho cuerpo tubular un pasaje en cuyo interior se encuentran alojados: un elemento de obturación, movible entre una posición de apertura y una posición de cierre; un tope de retención del elemento de obturación en Ia posición de apertura, siendo dicho tope de un material soluble en gasolina e insoluble en gasóleo, y un elemento elástico que actúa sobre el elemento de obturación y provoca su desplazamiento hacia Ia posición de cierre cuando se disuelve el tope debido al repostaje inadecuado con gasolina.The valve comprises a tubular body, open at its ends, and designed to position itself tightly inside the mouth of the fuel tank; said tubular body defining a passage inside which are housed: a sealing element, movable between an open position and a closed position; a retaining stop of the sealing element in the opening position, said stop being of a material soluble in gasoline and insoluble in diesel, and an elastic element that acts on the sealing element and causes its movement towards the closed position when dissolves the stop due to improper refueling with gasoline.
En Ia posición normal de uso Ia válvula está abierta, permitiendo el paso del gasóleo por su interior hacia el depósito. Sin embargo, cuando se intenta repostar con gasolina, se produce Ia disolución rápida del tope y se cierra Ia válvula automáticamente por Ia acción del elemento elástico mencionado anteriormente. Al cerrarse Ia válvula, Ia gasolina que suministra el boquerel se acumula rápidamente en el interior del cuerpo tubular de Ia válvula, activando el sistema de seguridad de dicho boquerel, el cual deja de suministrar gasolina. La pequeña cantidad de gasolina que pueda haber caído en el depósito se diluye sin problemas con el gasóleo de relleno, evitando Ia avería del vehículo. En caso de estar realizando un llenado manual, por ejemplo mediante una garrafa, el bloqueo de Ia válvula evita también Ia entrada del líquido, rebosando dicho líquido hacia al exterior cuando alcanza Ia cota de Ia boca de llenado.In the normal position of use, the valve is open, allowing the passage of diesel fuel inside to the tank. However, when trying to refuel with gasoline, the rapid dissolution of the stop occurs and the valve is automatically closed by the action of the elastic element mentioned above. When the valve is closed, the gasoline that supplies the nozzle quickly accumulates inside the tubular body of the valve, activating the safety system of said nozzle, which stops supplying gasoline. The small amount of gasoline that may have fallen into the tank is diluted without problems with the filling diesel, avoiding the breakdown of the vehicle. If a manual filling is being carried out, for example by means of a bottle, the blocking of the valve also prevents the entry of the liquid, said liquid overflowing towards the outside when it reaches the level of the filling mouth.
El elemento de obturación es preferentemente tipo mariposa y se encuentra articulado por su zona media sobre el cuerpo tubular mediante un eje transversal.The sealing element is preferably butterfly type and is articulated by its middle area on the tubular body by a transverse axis.
De acuerdo con Ia invención el cuerpo tubular presenta en su extremo posterior una pluralidad de prolongaciones laminares dispuestas de forma divergente, configurando un embudo que facilita el posicionamiento centrado del cuerpo tubular en el conducto de entrada del depósito de combustible y que permite orientar el flujo de combustible entrante hacia el interior del cuerpo tubular. Esto asegura el correcto funcionamiento de Ia válvula, ya que el paso de fluido por el interior del conducto, mojando el tope, está asegurado al repostar el depósito.In accordance with the invention, the tubular body has at its rear end a plurality of laminar extensions arranged in a divergent manner, configuring a funnel that facilitates the centered positioning of the tubular body in the inlet duct of the fuel tank and which allows to guide the flow of incoming fuel into the tubular body. This ensures the proper functioning of the valve, since the passage of fluid through the inside of the duct, wetting the stop, is assured when refueling the tank.
A su vez, el cuerpo tubular presenta en su extremo posterior una tira alargada que remata en un aro abierto de sujeción. Esta tira queda lateralmente próxima a las paredes del conducto de entrada de combustible y el aro queda fácilmente accesible en Ia boca del depósito. Su expansión dentro de Ia boca de llenado permite su ajuste óptimo y evita que se introduzca excesivamente en el conducto citado.In turn, the tubular body has at its rear end an elongated strip that ends in an open clamping ring. This strip is laterally close to the walls of the fuel inlet duct and the ring is easily accessible in the mouth of the tank. Its expansion within the filling mouth allows its optimal adjustment and prevents it from being excessively introduced into the said duct.
Dicho aro abierto comprende un asa abatible, de forma aproximadamente semicircular, para facilitar Ia extracción de Ia válvula. El asa, preferentemente metálica, queda a un lado en posición inoperante, evitando toda molestia al introducir el boquerel de llenado o el tapón de cierre en Ia boca de llenado. A su vez, es fácil disponer el asa en una posición operativa, sobresaliendo hacia el exterior, para permitir Ia extracción Ia válvula simplemente tirando de ella. El aro abierto presenta en su cara interior, al menos, una prominencia para el apoyo estable del asa en Ia posición abatida o inoperante.Said open ring comprises a folding handle, approximately semicircular, to facilitate the removal of the valve. The handle, preferably metal, is placed in an inoperative position, avoiding any discomfort when introducing the filling nozzle or the closure plug in the filling mouth. In turn, it is easy to arrange the handle in an operative position, protruding outwards, to allow the valve to be removed simply by pulling it. The open ring has at least one prominence in its inner face for the stable support of the handle in the collapsed or inoperative position.
