ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
En las instalaciones hidráulicas se conocen válvulas con una triple función consistente en:In hydraulic installations, valves with a triple function consisting of:
a) Extraer el aire de las conducciones a medida que se van llenando de líquido o agua (efecto cinético). Función que concluye cuando la llegada del agua o líquido a la válvula empuja hacia arriba un flotador, cerrando herméticamente el orificio de salida de dicha válvula;a) Extract the air from the pipes as they are filled with liquid or water (kinetic effect). Function that concludes when the arrival of water or liquid to the valve pushes up a float, tightly closing the outlet orifice of said valve;
b) Extraer el aire de las conducciones con flujo de agua o líquido bajo presión (efecto automático).

Como se decía, se conocen válvulas ventosas que cumplen las funciones anteriormente comentadas mediante mecanismos múltiples, es decir, compuestos por gran número de piezas o partes, y ninguna de ellas consiguen optimizar su funcionamiento mediante un sistema mecánico sencillo compuesto de flotador y obturador actuando de forma combinada que proporciona un cierre totalmente hermético que elimina cualquier fuga de agua o líquido a baja presión, además de extraer altos caudales de aire automático.As it was said, windy valves are known that fulfill the previously mentioned functions by means of multiple mechanisms, that is to say, composed of a large number of parts or parts, and none of them manage to optimize their operation by means of a simple mechanical system composed of float and shutter acting as combined form that provides a completely hermetic seal that eliminates any leakage of water or liquid at low pressure, in addition to extracting high automatic air flow rates.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La válvula ventosa de triple función y de gran caudal que se describe, ha sido concebida para resolver la problemática anteriormente expuesta, de manera que constituyéndose, como es convencional, a partir de un cuerpo general cilindrico y hueco en el que va montado un flotador asociado a un elemento de cierre, denominado obturador, que, en determinadas posiciones, evita la salida del aire e incluso del líquido o agua de la instalación en la que es aplicable la válvula. Se decía que a partir de estas características la válvula de la invención presenta la particularidad de que el obturador va montado con carácter desplazable dentro del cuerpo del flotador, y una parte del mismo formado por una cabeza, con junta de estanqueidad con perfil en "V", que queda enfrentada al orificio de salida cinético del cuerpo de la válvula, y por debajo de esa cabeza, comunicada con el correspondiente conducto de dicho obturador, unas derivaciones rígidas laterales o racores en las que se acoplan conductos de silicona que, en sus extremos libres, son portadores de esferas con un orificio de paso y un elemento de sujeción y acoplamiento al extremo del respectivo conducto de silicona. El obturador se vincula al flotador, a través de un vastago axial y pasante por todo el cuerpo del flotador y fijado mediante una tuerca prevista en el extremo inferior de ese vastago, todo ello de manera tal que el flotador en posición de reposo queda apoyado sobre la parte inferior del cuerpo de válvula, dejando salir el aire a través del conducto de salida cinético, como consecuencia de que el obturador, en virtud de estar vinculado al flotador, está igualmente desplazado hacia abajo, es decir separado de ese orificio de salida de aire cinético del cuerpo valvular, mientras que cuando va subiendo el nivel de líquido o agua en dicho cuerpo valvular, el flotador se va desplazando en sentido ascendente, arrastrando consigo al obturador que cierra, a través de la junta con perfil en "V",alojada en su cabeza, el propio orificio de salida cinético del cuerpo valvular, posibilitando al aire salir a través de los conductos de silicona en comunicación con el conducto del obturador. Ahora bien, cuando el nivel de agua o líquido asciende lo suficiente, entonces el flotador se desplaza hacia arriba, haciendo que los conductos de silicona se plieguen por los brazos de palanca que forman precisamente las esferas acopladas en los extremos libres de dichos conductos de silicona, previéndose para ello que las esferas, guiadas, se deslicen y roten, a lo largo de unas pistas de perfil - convexo en el desplazamiento ascendente del flotador y correspondiente introducción de parte de la cabeza del obturador en dicho orificio de salida cinético y sellado hermético efectuado por la junta de perfil en "V", en cuyo caso se produce el estrangulamiento de los comentados conductos de silicona y por lo tanto evitando la salida tanto de aire como de agua al exterior del cuerpo valvular.The triple function and high flow suction valve described, has been designed to solve the problem previously exposed, so that constituting, as is conventional, from a general cylindrical and hollow body in which a float associated with a closing element, called a shutter, is mounted, which, in certain positions, prevents the escape of air and even of the liquid or water of the installation in which the valve is applicable. It was said that from these characteristics the valve of the invention has the peculiarity that the plug is mounted with a movable character inside the body of the float, and a part thereof formed by a head, with a sealing gasket with a "V" profile ", which faces the kinetic outlet orifice of the valve body, and below that head, communicated with the corresponding duct of said shutter, rigid lateral shunts or fittings in which silicone conduits are coupled which, in their free ends, are carriers of spheres with a passage hole and a fastener and coupling element to the end of the respective silicone conduit. The plug is connected to the float, through an axial rod and through the entire body of the float and fixed by a nut provided on the lower end of that rod, all in such a way that the float in rest position is supported on the lower part of the valve body, letting the air out through the kinetic outlet duct, as a consequence of the fact that the plug, by virtue of being connected to the float, is also displaced downwards, that is to say separated from that outlet port of kinetic air of the valvular body, while when the level of liquid or water in said valvular body is rising, the float moves upwards, dragging with it the closing shutter, through the joint with a "V" profile, housed in its head, the kinetic orifice of the valvular body itself, allowing air to exit through the silicone ducts in communication with the duct of the shutter. Now, when the level of water or liquid rises sufficiently, then the float moves upwards, causing the silicone ducts to fold down the lever arms that precisely form the spheres coupled at the free ends of said silicone ducts. , provided that the spheres, guided, slide and rotate, along some profile tracks - convex in the upward displacement of the float and corresponding introduction of part of the head of the shutter in said kinetic exit hole and hermetic seal made by the "V" profile joint, in which case the throttling of the said silicone ducts occurs and therefore avoiding the escape of both air and water outside the valve body.
De acuerdo con las características mencionadas, en base a la particular disposición del obturador sobre el flotador y en general sobre el cuerpo de la válvula, y permaneciendo dicho obturador fijo cerrando el orificio de salida cinético mediante la junta de perfil enAccording to the aforementioned characteristics, based on the particular disposition of the shutter on the float and in general on the valve body, and said shutter remaining fixed by closing the kinetic outlet opening by means of the profile joint in
"V", el movimiento vertical del flotador hacia arriba provoca el plegado de los conductos de silicona conectados a dicho obturador, produciendo el cierre hermético de la salida del líquido o agua y de aire de la instalación, mientras que su movimiento vertical hacia abajo provoca el despliegue de dichos conductos de silicona, dejando salir el aire "libre" o "automático" de la instalación."V", the vertical movement of the float upward causes the silicone conduits connected to said shutter to be folded, causing the liquid or water and air outlet of the installation to be hermetically sealed, while its downward vertical movement causes the deployment of said silicone ducts, letting the "free" or "automatic" air out of the installation.
Igualmente cabe destacar que el diseño dinámico y ligado del flotador y el obturador, permiten la purga de aire a alta velocidad, evitando el cierre prematuro.It should also be noted that the dynamic and linked design of the float and the shutter allow high-speed air purging, preventing premature closure.
También es de destacar el hecho de que el mecanismo de cierre formado por el obturador con la junta con perfil en "V" y los conductos de silicona, accionándose aquel por el flotador a través de los brazos de palanca rígidos que forman las esferas unidas en los extremos de los conductos de silicona, resulta un cierre totalmente hermético, no produciendo gotas de agua o líquido a baja presión, con la particularidad de que en el plegado y desplegado de los conductos de silicona y su posicionamiento en estado de reposo, constituyen un mecanismo de auto-limpieza, así como el drenaje del agua, al vaciarse la instalación a través del orificio axial del flotador por donde se desplaza la varilla o vastago del elemento de cierre.Also noteworthy is the fact that the closing mechanism formed by the shutter with the "V" profile gasket and the Silicone conduits, the one being activated by the float through the rigid lever arms that form the spheres joined at the ends of the silicone conduits, results in a completely hermetic closure, not producing drops of water or liquid at low pressure, with the particularity that in the folding and unfolding of the silicone ducts and their positioning in a state of rest, they constitute a self-cleaning mechanism, as well as water drainage, when the installation is emptied through the axial hole of the float where displaces the rod or rod of the closure element.
Finalmente cabe añadir que el obturador puede materializarse con una simetría axial de "n caras", permitiendo alojar "n vías" o "n orificios de salida de aire automático", para lo que el obturador dispondrá de "n conectores o racores" para "n conductos de silicona", con sus correspondientes "n brazos de palanca esféricos", disponiendo a su vez el flotador de "n pistas de deslizamiento y rodadura", por donde se desplazan los "n brazos de palanca esféricos".Finally, it should be added that the shutter can materialize with an axial symmetry of "n faces", allowing to accommodate "n tracks" or "n automatic air outlet holes", for which the shutter will have "n connectors or fittings" for " n silicone ducts ", with their corresponding" n spherical lever arms ", in turn providing the float with" n sliding and rolling tracks ", where the" n spherical lever arms "move.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
Como se puede ver en las figuras, la válvula de la invención incluye un cuerpo de válvula (1), con un conducto de salida (2), y en oposición al mismo un tramo de rosca (3) sobre el que se acopla una pieza denominada base de la válvula en forma cilíndrica(4) que cierra dicho cuerpo hueco (1) de válvula, estando esta base(4) dotada de un cuello roscado (5) para su acoplamiento al correspondiente conducto de la instalación en la que es aplicable la válvula en cuestión.As can be seen in the figures, the valve of the invention includes a valve body (1), with an outlet duct (2), and in opposition thereto a thread section (3) on which a part is coupled denominated cylindrical shaped valve base (4) that closes said hollow valve body (1), this base (4) being provided with a threaded neck (5) for its coupling to the corresponding conduit of the installation in which it is applicable The valve in question.
En el interior del cuerpo valvular, es decir el determinado por el cuerpo (1) y base(4), va montado un flotador (6), facultado de desplazarse axialmente en el interior, y de forma guiada a través de dos cursores verticales (7) en oposición diametral ubicados en su superficie lateral, que deslizan en respectivas guías establecidas al efecto en la parte interna del cuerpo valvular (1).Inside the valve body, that is, determined by the body (1) and base (4), a float (6) is mounted, capable of moving axially inside, and guided through two vertical cursors (7) in diametral opposition located on its lateral surface, which slide in respective guides established for this purpose in the internal part of the valvular body (1).
Ese flotador (6) se complementa con un obturador(8) que presenta una cabeza (9) con una configuración periférica apropiada para recibir el acoplamiento de una junta con perfil en "V" (10) que realiza un cierre perfectamente hermético sobre el asiento interno del conducto de salida cinético(2) del cuerpo valvular (1), ese obturador(8) presenta dos cursores verticales en oposición diametral ubicados en su superficie lateral(ll) que deslizan en respectivas guías situadas en el interior de una cavidad (12) ubicada en el propio flotador (6), en dicha cavidad se construyen unas pistas de deslizamiento y rodadura (13) para unas esferas (14) que seguidamente se comentarán.This float (6) is complemented by a shutter (8) that has a head (9) with an appropriate peripheral configuration to receive the coupling of a joint with a "V" profile (10) that makes a perfectly tight seal on the seat internal of the kinetic outlet duct (2) of the valve body (1), that obturator (8) has two vertical cursors in diametral opposition located on its lateral surface (ll) that slide in respective guides located inside a cavity (12 ) located in the float itself (6), in said cavity, sliding and rolling tracks (13) are constructed for spheres (14) that will be discussed below.
En la parte inferior del obturador (8) y concretamente entre sus prolongaciones de guiado (11), queda situada una varilla o vastago (15) a través del cual se acopla con el propio flotador (6), al ser pasante ese vastago o varilla (15) axialmente al flotador (6) y fijarse mediante una tuerca (16) o elemento similar.In the lower part of the shutter (8) and specifically between its guide extensions (11), a rod or rod (15) is placed through which it is coupled with the float itself (6), when that rod or rod is through (15) axially to the float (6) and fixed using a nut (16) or similar element.
Además, el obturador (8) define por debajo de su cabeza (9), un conducto (17) del que se derivan externa y lateralmente de forma inclinada sendos racores (18) en los que se acoplan respectivos conductos de silicona (19) sobre cuyo otro extremo es donde se acoplan las esferas (14), siendo éstas los elementos que deslizan y rotan sobre las pistas (13)ubicadas en la cavidad (12) del flotador (6). Dichas esferas, (14) tienen una perforación diametral que permite el paso del aire y mediante unos conectores internos(20) fijar los conductos de silicona(19). En el acoplamiento entre el cuerpo de válvula (1) y la base de la válvula (4) interviene una junta tórica de estanqueidad (21).In addition, the shutter (8) defines below its head (9), a conduit (17) from which two fittings (18) are derived externally and laterally inclined in which respective silicone conduits (19) are coupled on whose other end is where the spheres (14) are coupled, these being the elements that slide and rotate on the tracks (13) located in the cavity (12) of the float (6). Said spheres, (14) have a diametral perforation that allows the passage of air and by means of internal connectors (20) fix the silicone conduits (19). In the coupling between the body of valve (1) and the valve base (4) intervenes an o-ring seal (21).
De acuerdo con las características de la válvula referida, el funcionamiento es como sigue:According to the characteristics of the referred valve, the operation is as follows:
Inicialmente, tanto la instalación como la válvula conectada a ella está descargada de líquido o agua, con lo que la válvula está en reposo y el aire en el interior a la presión atmosférica. En esa situación el flotador (6), por acción de la gravedad, se apoya en la base del cuerpo valvular (1), y el obturador(8) alojado en la cavidad (12) del flotador (6) en la posición más elevada respecto de éste, encontrándose los conductos de silicona (19) desplegados, manteniéndose en esta posición relativa inicial entre el flotador (6) y el obturador(8), como se representa en la figura 2. Cuando empieza a llenarse la instalación, el aire que hay en la misma, empujado por la presión del agua, comienza a salir libremente a través del orificio de salida cinético (2), debido a la diferencia de presión con el exterior. El obturador (8) se mantiene separado de las proximidades de ese orificio de salida cinético (2), ligado por la varilla o vastago (15) al flotador (6). El caudal de aire evacuado puede ser muy elevado, del orden de 200 m3/h, siendo la posición del flotador (6) y del obturadorInitially, both the installation and the valve connected to it are discharged from liquid or water, so that the valve is at rest and the air inside at atmospheric pressure. In that situation, the float (6), by gravity, rests on the base of the valve body (1), and the shutter (8) housed in the cavity (12) of the float (6) in the highest position with respect to it, the silicone conduits (19) being deployed, being kept in this initial relative position between the float (6) and the plug (8), as shown in Figure 2. When the installation begins to fill, the air that is in it, pushed by the pressure of the water, begins to leave freely through the kinetic exit hole (2), due to the difference in pressure with the outside. The plug (8) is kept separate from the vicinity of that kinetic exit hole (2), linked by the rod or rod (15) to the float (6). The evacuated air flow can be very high, of the order of 200 m 3 / h, the position of the float (6) and the shutter being
(8) la mostrada en la figura 2.(8) the one shown in figure 2.
Cuando el aire cinético ha salido, el agua entra en la válvula empujando al flotador (6) hacia arriba, de manera que en el desplazamiento de éste se arrastra consigo al obturador (8) y la cabezaWhen the kinetic air has gone out, the water enters the valve by pushing the float (6) upwards, so that in its displacement, the shutter (8) is dragged along with it and the head
(9) de éste entra parcialmente en el orificio de salida cinético (2), produciéndose el cierre hermético por apoyo de la junta con perfil en "V(IO) sobre el asiento interno de dicho orificio (2). Entonces el aire cinético entra ahora por las esferas (14) establecidas en los extremos de los conductos de silicona (19), accediendo al conducto axial (17) del obturador (8) y saliendo al exterior por el orificio (2) del cuerpo de válvula, como se representa en la figura 3.(9) of the latter partially enters the kinetic outlet opening (2), the seal being produced by support of the joint with a "V" (IO) profile on the internal seat of said hole (2). Then the air Kinetic now enters the spheres (14) established at the ends of the silicone ducts (19), accessing the axial duct (17) of the plug (8) and exiting outside through the hole (2) of the valve body, as It is represented in figure 3.
El flotador (6) sigue ascendiendo hasta que el empuje que experimenta se traduce en sendas fuerzas hacia arriba aplicadas a las esferas (14), rotando éstas y deslizándose a lo largo de las pistas convexas (13) de la cavidad (12) del flotador (6), que producen, respectivamente, un momento de fuerzas con respecto al eje de giro situado en la zona de plegado de los conductos de silicona que provoca el plegado y estrangulamiento de los mismos (19), como se representa en la figura 4, posición que además corresponde a la de situación más baja del obturador con respecto al flotador(δ), evitando con ello que salga flujo alguno, ya sea de aire cinético y de agua al exterior.The float (6) continues to rise until the thrust it experiences translates into upward forces applied to the spheres (14), rotating them and sliding along the convex tracks (13) of the float cavity (12) (6), which produce, respectively, a moment of forces with respect to the axis of rotation located in the area of folding of the silicone conduits that causes them to be folded and strangled (19), as shown in Figure 4 , a position that also corresponds to that of the lowest location of the shutter with respect to the float (δ), thereby preventing any flow, either of kinetic air and water outside.
Ahora bien, cuando una bolsa de aire "libre" o "automático" se acumula en la parte superior del cuerpo (1) de la válvula, el nivel de agua desciende de la misma, descendiendo también el flotador (6), lo que hace que los conductos de silicona (19) se desplieguen y se abra el paso para que dicho aire automático salga al exterior. Cuando la citada bolsa de aire ha sido evacuada, la subida del nivel de agua en la válvula vuelve a elevar el flotador (6) y a producir el estrangulamiento de los conductos de silicona (19) y el cierre total de la válvula. Durante este proceso, el obturador (8) se encuentra adsorbido por medio de la junta de perfil en "V(IO) al asiento del orificio cinético del cuerpo de válvula, debido al diferencial de presión (la presión interior de la válvula es mayor que la atmosférica). Este proceso automático de purgado de aire se repite cada vez que una bolsa de aire de volumen suficiente desplaza al flotador (6) hacia abajo lo suficiente como para que los conductos de silicona (19) se desplieguen.However, when a "free" or "automatic" air bag accumulates in the upper part of the body (1) of the valve, the water level drops from it, the float (6) also descends, which makes that the silicone ducts (19) are deployed and the passage is opened for said automatic air to go outside. When the aforementioned air bag has been evacuated, the increase in the water level in the valve raises the float again (6) and causes the throttling of the silicone ducts (19) and the total closing of the valve. During this process, the plug (8) is adsorbed by means of the "V (IO) profile joint to the seat of the kinetic orifice of the valve body, due to the pressure differential (the internal pressure of the valve is greater than atmospheric) This automatic air purge process is repeated every time a volume air bag enough displaces the float (6) down enough for the silicone conduits (19) to deploy.
Cuando la instalación se vacía, el nivel de agua desciende, también descenderá el flotador (6) y se libera de su asiento la junta de perfil en "V" del obturador (8) que también desciende. En tales circunstancias, el orificio de salida (2) queda abierto para que entre aire a ocupar el lugar que deja el agua en la instalación, de manera que durante esta etapa la posición del flotador (6) y del obturador (8) es la mostrada en la figura 2. When the installation is emptied, the water level drops, the float (6) will also descend and the "V" profile seal of the plug (8) that also descends is released from its seat. In such circumstances, the outlet orifice (2) is open for air to occupy the place left by the water in the installation, so that during this stage the position of the float (6) and the shutter (8) is the shown in figure 2.
