VÁLVULA ANTI-RETORNO DE DOBLE CLAPETA DE ALTA SENSIBILIDADHIGH SENSITIVITY DOUBLE CLAPPER ANTI-RETURN VALVE
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a una válvula anti-retorno de doble clapeta de alta sensibilidad, prevista para controlar la transferencia de aire entre un volumen de control y el exterior, de manera tal que ese volumen de control y el exterior están conectados precisamente mediante la válvula de la invención, la cual está dotada de dos orificios que comunican con el exterior y otros dos que comunican con el volumen de control. Uno de dichos orificios siempre es de salida y el otro siempre es de entrada.The present invention refers to a highly sensitive double-flap non-return valve, designed to control the transfer of air between a control volume and the exterior, in such a way that that control volume and the exterior are precisely connected by means of the valve of the invention, which is equipped with two orifices that communicate with the outside and another two that communicate with the control volume. One of these holes is always an outlet and the other is always an inlet.
La válvula de la invención es aplicable en distintos sectores como son el sub-acuático, salvamento, atmósferas tóxicas, bombeo de fluidos, respiración asistida, válvulas de uso sanitario y otros.The valve of the invention is applicable in different sectors such as underwater, rescue, toxic atmospheres, pumping fluids, assisted breathing, valves for sanitary use and others.
El objeto de la invención es proporcionar una válvula anti-retorno de alta sensibilidad en su funcionamiento, que no se vea afectada en dicho funcionamiento por la gravedad, ni precise de elementos elásticos que requieran niveles de presión mínimos mantenidos para su correcto funcionamiento.The object of the invention is to provide a highly sensitive non-return valve in its operation, which is not affected in said operation by gravity, nor does it require elastic elements that require minimum pressure levels maintained for its correct operation.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Las válvulas anti-retorno existentes actualmente en el mercado requieren de un gradiente de presión para activar su apertura, de manera que para realizar el cierre es necesaria la desaparición o inversión de tal gradiente de presión.The non-return valves currently on the market require a pressure gradient to activate their opening, so that in order to close it, the disappearance or inversion of such pressure gradient is necessary.
En tal sentido, existen válvulas anti-retorno que funcionan de forma gravitatoria, de manera que almacenan energía o se bloquean cuando hay un gradiente de presión, y se liberan cuando cesa dicho gradiente. Estas válvulas disponen de elementos que suben y que regresan a su posición inicial cuando desaparece el gradiente de presión. In this sense, there are non-return valves that work gravitationally, so that they store energy or are blocked when there is a pressure gradient, and are released when said gradient ceases. These valves have elements that rise and return to their initial position when the pressure gradient disappears.
Las válvulas de clapeta oscilante, almacenan energía elástica, disponiendo de elementos tales como muelles o diafragmas que permiten su funcionamiento sin depender de la gravedad como sucede en el caso anteriormente descrito.Oscillating flap valves store elastic energy, having elements such as springs or diaphragms that allow their operation without depending on gravity as in the case described above.
Sin embargo en este tipo de válvulas el gradiente de presiones debe mantenerse por encima de la resistencia elástica que ofrece el material.However, in this type of valve, the pressure gradient must be kept above the elastic resistance offered by the material.
En otro grupo de válvulas anti-retorno están las de pistón o bola que, además de verse afectadas por la gravedad, pueden estar adicionalmente asistidas por elementos elásticos tales como muelles, con las limitaciones anteriormente descritas.In another group of non-return valves, there are piston or ball valves which, in addition to being affected by gravity, can be additionally assisted by elastic elements such as springs, with the limitations previously described.
En cualquiera de los casos las válvulas descritas son complejas estructuralmente y lo más importante, su fiabilidad y funcionamiento está limitado por un gradiente de presión mínima mantenida que debe superar en todo momento la gravedad o elasticidad de un material para accionarse.In any of the cases the valves described are structurally complex and, most importantly, their reliability and operation is limited by a minimum maintained pressure gradient that must at all times overcome the gravity or elasticity of a material in order to actuate.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
La válvula anti-retorno de doble clapeta de alta sensibilidad, que se preconiza, presenta una serie de características que resuelven los problemas de las válvulas anti-retorno convencionales, resultando una válvula sencilla, más precisa, con menores gradientes de presión y que no necesita mantener el gradiente para mantener accionada la válvula.The highly sensitive double-flap non-return valve, which is recommended, presents a series of characteristics that solve the problems of conventional non-return valves, resulting in a simple, more precise valve, with lower pressure gradients and that does not need maintain the gradient to keep the valve actuated.
Para ello, y de forma más concreta, la válvula de la invención se constituye a partir de un cuerpo base en el que están establecidos dos orificios para ubicación de sendas clapetas que van montadas sobre un mismo eje, cuyos extremos apoyan en sendas tapas, interior y exterior, del propio cuerpo base.For this, and more specifically, the valve of the invention is constituted from a base body in which two holes are established for the location of the clappers that are mounted on the same shaft, the ends of which are supported by the respective covers, inside and outside, of the base body itself.
Las clapetas pueden girar tanto en sentido horario como en sentido anti-horario, siempre solidariamente para sumar los esfuerzos, de manera que tanto en un sentido como en otro una de las clapetas realiza, por ejemplo, el cierre del orificio de entrada del exterior al volumen de control, permitiendo la salida por el orificio de salida, o bien permitiendo la entrada del exterior al volumen de control, cerrando la salida de éste y abriendo el orificio de entrada. En todos los casos la entrada de fluido desde el exterior al volumen de control se realiza por el orificio de entrada y la salida de fluido proveniente del volumen de control se realiza por el orificio de salida.The flaps can rotate both clockwise and anti-clockwise, always jointly and severally to add the forces, so that both in one direction and in the other one of the flaps performs, for example, the closure of the entrance hole from the outside to the control volume, allowing the exit through the outlet orifice, or allowing the entrance of the outside to the control volume, closing the outlet of it and opening the inlet orifice. In all cases the fluid inlet from the outside to the control volume is performed through the inlet port and the fluid outlet from the control volume is performed through the outlet port.
El principio de funcionamiento de la válvula está basado en la diferencia de presiones entre el volumen de control y la presión exterior, de manera que cuando la presión exterior es mayor que la presión dentro del volumen de control, las clapetas que conforman el mecanismo de cierre giran un determinado ángulo en el sentido contrario a las agujas del reloj, permitiendo la entrada del fluido a través de la boca de entrada y bloqueando la entrada de fluido proveniente de la boca de salida, mientras que cuando la presión exterior es menor que la presión dentro del volumen de control, entonces el sistema de cierre gira un determinado ángulo en el sentido de las agujas del reloj, permitiendo la salida de fluido hacia la boca de salida y bloqueando la salida del fluido hacia la boca de entrada.The operating principle of the valve is based on the pressure difference between the control volume and the external pressure, so that when the external pressure is greater than the pressure within the control volume, the clappers that make up the closing mechanism rotate a certain angle in an anti-clockwise direction, allowing the entry of the fluid through the inlet and blocking the entry of fluid from the outlet, while when the external pressure is less than the pressure within the control volume, then the closure system rotates a certain angle in a clockwise direction, allowing the fluid to exit towards the outlet port and blocking the outlet of the fluid to the inlet port.
De esta forma se consigue una válvula anti-retorno con una alta sensibilidad en su funcionamiento, que no se ve afectada en su funcionamiento por la gravedad, ni precisa de elementos elásticos que limiten la presión o niveles de presión mínimos para su correcto funcionamiento. Además de no requerir un gradiente de presión mantenido para que la válvula mantenga su estado, bien de apertura o de cierre.In this way, a non-return valve is achieved with a high sensitivity in its operation, which is not affected in its operation by gravity, nor does it require elastic elements that limit the pressure or minimum pressure levels for its correct operation. In addition to not requiring a sustained pressure gradient for the valve to maintain its state, either opening or closing.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION
A la vista de las figuras reseñadas, puede observarse como la válvula anti-retorno de doble clapeta de alta sensibilidad objeto de la presente solicitud comprende un cuerpo base (1), con dos tapas, una tapa exterior (2) y una tapa interior (3), cuerpo base (1) en cuyo interior van montadas dos clapetas (4,5), que pueden girar respecto de un eje común (6) al que ambas son solidarias, estando dichas clapetas (4,5) desfasadas entre sí.In view of the figures outlined, it can be seen how the high-sensitivity double-flap non-return valve object of the present application comprises a base body (1), with two covers, an outer cover (2) and an inner cover (3), base body (1) inside which two clappers (4,5) are mounted, which can rotate with respect to a common axis (6) to which both they are joint, said flaps (4,5) being out of phase with each other.
De forma más concreta, en el cuerpo base (1) se definen sendas cámaras a uno y otro lado del mismo en el que juegan las clapetas (4,5), y que se cierran mediante las tapas exterior (2) e interior (3), cámaras que se comunican entre sí a través de un orificio central (1’) por el que es pasante ajustadamente el cuerpo central y cilindrico (4’-5’) hueco de ambas clapetas (4,5).More specifically, in the base body (1), chambers are defined on either side of it in which the clappers (4,5) play, and which are closed by means of the outer (2) and inner (3) covers. ), chambers that communicate with each other through a central hole (1 ') through which the central and cylindrical body (4'-5') of both clappers (4,5) is tightly passed.
De esta forma, la primera clapeta (4) asociada a la cara y consecuentemente tapa exterior (2) del dispositivo se comunica a través del hueco interior de su cuerpo central y cilíndrico (4’) con la boca de entrada (10) prevista para la válvula, haciendo de nexo de comunicación con la segunda clapeta (5) a través del hueco de su cuerpo central y cilindrico (5’), el cual presenta unos orificios (5’’) que comunican la boca de entrada (10) con la cámara interior del cuerpo principal (1) en la que se definen unas conducciones hacia un volumen de control (8), volumen de control (8) que se comunicará igualmente con la cámara exterior del cuerpo principal (1) en la que juega la primera clapeta (4), y en la que se definen unas conducciones que se comunican con respectivas bocas de salida (9) previstas en la tapa exterior (2).In this way, the first clapper (4) associated with the face and consequently the outer cover (2) of the device communicates through the inner hollow of its central and cylindrical body (4 ') with the inlet mouth (10) provided for the valve, acting as a communication link with the second clapper (5) through the hole in its central and cylindrical body (5 '), which has holes (5' ') that communicate the inlet mouth (10) with the inner chamber of the main body (1) in which conduits are defined to a control volume (8), a control volume (8) that will also communicate with the outer chamber of the main body (1) in which the first clapper (4), and in which pipes are defined that communicate with respective outlet openings (9) provided in the outer cover (2).
Así pues, el desfase entre clapetas (4,5) es tal que cuando la segunda clapeta (5) esté en posición de apertura, es decir permitiendo la admisión de fluido a través de la boca de entrada (10) hacia el volumen de control (8), la primera clapeta (4) bloquee la salida de dicho volumen de control hacia las bocas de salida (9).Thus, the phase shift between flaps (4,5) is such that when the second flap (5) is in the open position, that is, allowing the admission of fluid through the inlet port (10) towards the control volume (8), the first clapper (4) blocks the outlet of said control volume towards the outlet ports (9).
En la figura 3 se muestra la segunda clapeta (5) y en la figura 4 la primera clapeta (4), de manera que en correspondencia con el núcleo central (5’) de la segunda clapeta (5) se establece la boca de entrada (10) hacia el correspondiente volumen de control (8) establecido en el propio cuerpo de válvula (1), de manera que, volviendo nuevamente a la figura 4, la primera clapeta (4) es susceptible de girar un ángulo a mediante el que se comunica el volumen de control (8) con sendas bocas de salida (9), o bien girar en sentido contrario a las agujas del reloj para bloquear dicho volumen de control (8). In figure 3 the second clapper (5) is shown and in figure 4 the first clapper (4), so that in correspondence with the central core (5 ') of the second clapper (5) the inlet mouth is established (10) towards the corresponding control volume (8) established in the valve body (1) itself, so that, returning again to figure 4, the first clapper (4) is capable of turning an angle a by which the control volume (8) is communicated with the respective outlet ports (9), or it is rotated in an anti-clockwise direction to block said control volume (8).
Así pues, y tal y como se muestra de forma esquemática en la figura 5B, cuando la presión exterior a la boca de salida (9) es mayor que la presión dentro del volumen de control (8) entonces el mecanismo de cierre gira un ángulo a en sentido contrario a las agujas del reloj, permitiendo la entrada de fluido proveniente de la boca de entrada (10), y bloqueando la entrada de fluido proveniente de la boca de salida.Thus, and as shown schematically in figure 5B, when the pressure outside the outlet (9) is greater than the pressure inside the control volume (8) then the closing mechanism rotates an angle a in an anti-clockwise direction, allowing the entry of fluid from the inlet port (10), and blocking the entry of fluid from the outlet port.
Por su parte, cuando la presión exterior, es decir en la boca de salida (9) es menor que la presión dentro del volumen de control, entonces el mecanismo de cierre gira un ángulo a en el sentido de las agujas del reloj, permitiendo la salida del fluido contenido en el volumen de control (8) hacia la boca de salida (9), tal como muestra la figura 6B.On the other hand, when the external pressure, that is to say in the outlet mouth (9), is less than the pressure inside the control volume, then the closing mechanism rotates an angle a in a clockwise direction, allowing the outlet of the fluid contained in the control volume (8) towards the outlet port (9), as shown in figure 6B.
El dispositivo así descrito siempre realiza la absorción del fluido por la boca de entrada (10) y lo expulsa por la boca de salida (9), evitando la salida de fluido por la boca de entrada (10) y la entrada de fluido por la boca de salida (9).The device thus described always absorbs the fluid through the inlet port (10) and expels it through the outlet port (9), preventing the fluid from leaving the inlet port (10) and the fluid entering through the outlet mouth (9).
En las figuras 7, 8, 9 y 10 se muestran representaciones esquemáticas del funcionamiento de admisión y salida del fluido.Schematic representations of fluid intake and outlet operation are shown in Figures 7, 8, 9 and 10.
Así, en la figura 7 se muestra el flujo de entrada de aire en la posición de admisión y en la figura 8 el bloqueo de flujo de entrada de aire por la boca de salida.Thus, in figure 7 the air inlet flow is shown in the intake position and in figure 8 the air inlet flow blockage through the outlet mouth is shown.
Es decir, que cuando la presión exterior en la boca de entrada (10) es mayor que la presión en el volumen de control (8), la posición de la segunda clapeta (5) permite la entrada de fluido por la boca de entrada (10), mientras que en la figura 8 se puede ver como cuando la presión exterior en la boca de salida (9) es mayor que la presión en el volumen de control (8), entonces la posición de la primera clapeta (4) impide la entrada de fluido por la boca de salida (9).That is, when the external pressure in the inlet port (10) is greater than the pressure in the control volume (8), the position of the second clapper (5) allows the entry of fluid through the inlet port ( 10), while in figure 8 it can be seen how when the external pressure in the outlet mouth (9) is greater than the pressure in the control volume (8), then the position of the first clapper (4) prevents the fluid inlet through the outlet (9).
Sin embargo, en las figuras 9 y 10, se muestra el bloqueo de flujo de salida por la boca de entrada (10) y la salida de aire en la posición de expulsión, respectivamente. Es decir, que cuando la presión exterior en la boca de entrada (10) es menor que la presión en el volumen de control (8), entonces la segunda clapeta (5) impide la salida de fluido por la boca de entrada (10), mientras que cuando la presión exterior en la boca de salida (9) es menor que la presión en el volumen de control (8), entonces la posición de la primera clapeta (4) permite la salida del fluido por la boca de salida (9).However, in Figures 9 and 10, the outlet flow blockage is shown through the inlet port (10) and the air outlet in the expulsion position, respectively. That is, when the external pressure in the inlet mouth (10) is lower than the pressure in the control volume (8), then the second clapper (5) prevents the fluid from leaving the inlet mouth (10) , whereas when the external pressure in the outlet (9) is less than the pressure in the control volume (8), then the position of the first clapper (4) allows the fluid to exit through the outlet (9).
Se consigue así una válvula de alta sensibilidad, dado que la diferencia de presión entre el volumen de control y el exterior que acciona la doble clapeta es muy bajo, a lo que hay que añadir el hecho de que el único punto de apoyo del mecanismo de cierre son los extremos del eje, siendo el peso muy bajo, estando el mecanismo perfectamente equilibrado.In this way, a highly sensitive valve is achieved, since the pressure difference between the control volume and the exterior that operates the double flap is very low, to which must be added the fact that the only support point of the control mechanism closing are the ends of the shaft, the weight being very low, the mechanism being perfectly balanced.
Si bien y como se ha dicho con anterioridad la válvula así descrita puede tener múltiples aplicaciones, una de dichas aplicaciones podría ser la respiración en atmósferas tóxicas, en ausencia de oxígeno o bajo el agua, de manera que, añadiendo un segundo volumen de control, podrían solucionarse los problemas de vaho en los cascos en los que sería implantable este tipo de válvulas para controlar la respiración del usuario. Although and as previously mentioned, the valve thus described can have multiple applications, one of said applications could be breathing in toxic atmospheres, in the absence of oxygen or under water, so that, by adding a second control volume, Fog problems could be solved in helmets in which this type of valve would be implantable to control the user's breathing.
