Description

Válvula de esfera.Ball valve

Objeto de la invenciónObject of the invention

La presente invención se refiere a una válvula, de las comúnmente denominadas "de esfera", por cuanto que el obturador consiste en una esfera giratoria capaz de adoptar dos posiciones límite, una de apertura y otra de cierre.The present invention relates to a valve, of the so-called "sphere", because the shutter consists of a rotating sphere capable of adopting two limit positions, one of opening and another of closing.

El objeto de la invención es conseguir una válvula resistente a las bajas temperaturas, concretamente una válvula cuyo obturador esférico no se pueda romper por efecto de la congelación del agua, merced a que en situación de cierre se mantiene vacío.The object of the invention is to achieve a low temperature resistant valve, specifically a valve whose spherical plug cannot break due to the water freezing, thanks to the closing situation keep empty.

Antecedentes de la invenciónBackground of the invention

Como es sabido las válvulas de esfera están constituidas mediante un cuerpo valvular, generalmente estructurado mediante dos piezas acoplables entre sí por rosca, definiendo entre ellas un alojamiento para un obturador esférico, asistido por una pareja de juntas, contando dicho obturador con un amplio paso diametral para el agua, prolongándose el cuerpo valvular en un cuello hueco a través del que accede hasta el obturador el eje de accionamiento del mismo, eje asociado por su extremidad exterior a una maneta de accionamiento manual, de manera que dicha maneta es susceptible de adoptar dos posiciones, una en la que el orificio o paso diametral del obturador queda alineado con los dos tramos de conducción en los que se encuentra intercalada la válvula, permitiendo el paso del agua, y otra en la que gira 90º quedando dicho paso diametral desfasado unos 90º con respecto al eje valvular, y consecuentemente en situación de cierre.As is known, the ball valves are constituted by a valvular body, generally structured by two pieces that can be attached to each other by thread, defining between they a housing for a spherical shutter, assisted by a couple of joints, counting said shutter with a wide step diametral for water, prolonging the valve body in a hollow neck through which the shaft of access to the shutter drive thereof, axis associated by its outer extremity to a manually operated handle, so that said handle is liable to adopt two positions, one in which the hole or diametral passage of the shutter is aligned with the two sections of conduit in which the valve is interleaved, allowing the passage of water, and another in which it rotates 90º being said diametral step offset about 90º with respect to the axis valve, and consequently in a situation of closure.

Este tipo de válvulas, funcionalmente muy eficientes, presentan en la práctica un problema derivado de que en el momento en que su obturador pasa de la situación de apertura a la situación de cierre, se queda lleno de agua, lo que trae consigo que ante una congelación de la misma se produzca la rotura del obturador.This type of valves, functionally very efficient, they present in practice a problem derived from that in the moment your shutter goes from the opening situation to the closing situation remains full of water, which brings with it that before a freeze of the same the breakage of the shutter.

Descripción de la invenciónDescription of the invention

La válvula de esfera que la invención propone, manteniendo las prestaciones de las válvulas convencionales de este tipo, resuelve de manera plenamente satisfactoria la problemática anteriormente expuesta, por cuanto que su estructuración específica permite y asegura el vaciado del obturador cada vez que se produce el cierre valvular.The ball valve proposed by the invention, maintaining the performance of the conventional valves of this type, solves the problem fully satisfactorily previously exposed, since its specific structuring allows and ensures shutter emptying every time it occurs the valve closure.

Para ello y de forma mas concreta la válvula que la invención propone está constituida de forma análoga a cualquier válvula convencional, en lo que se refiere a la estructura del cuerpo valvular, el obturador y sus medios de accionamiento, pero con la especial particularidad de que el citado cuerpo valvular incorpora un orificio radial, desfasado 90º con respecto al paso diametral de dicho obturador y situado perpendicularmente con respecto al eje de giro del mismo, de manera que cuando se produce el accionamiento de tal obturador en sentido de cierre valvular, el citado orificio queda enfrentado a la boca de salida del cuerpo valvular, es decir a la conducción que se queda sin presión con el cierre, lo que hace que dicho cuerpo valvular quede vacío, o al menos con una cantidad de agua totalmente insuficiente como para que su congelación pueda provocar la rotura del obturador.For this and more specifically the valve that the proposed invention is constituted analogously to any conventional valve, as regards the structure of the valve body, the shutter and its actuating means, but with the special feature that said valve body incorporates a radial hole, 90º offset with respect to the passage diametral of said shutter and located perpendicularly with with respect to the axis of rotation thereof, so that when it occurs the actuation of such a shutter in the direction of valve closure, the said hole is facing the mouth of the body valve, that is to say the conduction that runs out of pressure with the closure, which makes said valve body empty, or when less with a totally insufficient amount of water so that freezing may cause the shutter to break.

Realización preferente de la invenciónPreferred Embodiment of the Invention

A la vista de las figuras reseñadas, y en especial de las figuras 1 y 2, puede observarse como la válvula de esfera que se preconiza está constituida, como cualquier válvula convencional de este tipo, a partir de un cuerpo valvular materializado en dos piezas (1) y (2), acoplables entre sí mediante rosca (3) para permitir la interposición entre ellas del obturador esférico (4), con interposición de una pareja de juntas anulares (5-5') que aseguran la estanqueidad, prolongándose la pieza (1) en un cuello (6) hueco, a través del cual accede al interior del cuerpo el eje (7) de accionamiento del obturador esférico (4), fijado a una maneta (8) de accionamiento manual y rematado por su extremidad interna en una chaveta (9) que se acopla a una ranura (10) del obturador (4), rematándose las dos piezas unidas constitutivas del cuerpo valvular en sendos racores o sectores roscados (11-11'), coaxiales, susceptibles de resultar también coaxiales con el amplio paso (12) definido en el seno del obturador esférico (4), cuando la válvula se encuentra abierta, tal como muestra la figura 1, o de quedar desenfrentados a dicho paso (12) como en la situación de cierre mostrada en la figura 2.In view of the figures outlined, and in of figures 1 and 2, can be seen as the valve recommended sphere is constituted, like any valve conventional of this type, from a valve body materialized in two pieces (1) and (2), attachable with each other by thread (3) to allow interposition between them of the shutter spherical (4), with interposition of a pair of ring joints (5-5 ') that ensure the tightness, prolonging the piece (1) in a hollow neck (6), through which it accesses the inside the body the shutter drive shaft (7) spherical (4), fixed to a handle (8) of manual operation and topped by its inner tip in a key (9) that engages to a groove (10) of the shutter (4), finishing off the two pieces constitutive joints of the valvular body in two fittings or threaded sectors (11-11 '), coaxial, susceptible if it is also coaxial with the broad step (12) defined in the sine of the spherical plug (4), when the valve is open, as shown in figure 1, or to be discouraged to said step (12) as in the closing situation shown in the figure 2.

Pues bien, de acuerdo ya con la invención y a partir de esta estructuración básica y convencional, la válvula que se preconiza centra sus características en el hecho de que el citado obturador (4) incorpora además un orificio radial (13), perpendicular al amplio paso diametral (12) repetidamente citado, y a su vez perpendicular al eje (7) de accionamiento valvular, todo ello de forma que en la situación de apertura mostrada en la figura 1, el citado orificio (13) resulta inoperante por cuanto que queda enfrentado al cuerpo valvular (2), concretamente hacia una zona estanqueizada mediante las juntas (5-5') y la junta superior (14) o prensa-estopas que asiste al eje (7), mientras que cuando la válvula gira en sentido de cierre, tal como muestra la figura 2, el orificio (13) queda orientado hacia el racor de salida (11'), es decir hacia la zona de la conducción carente de presión, como anteriormente se ha dicho, lo que supone un vaciado al menos parcial del alojamiento definido en el seno del obturador (4) en tal situación de cierre, y lo que evita a su vez que una posible congelación del agua contenida en el mismo pudiera provocar su rotura, como anteriormente se ha dicho.Well, according to the invention and to from this basic and conventional structuring, the valve that it is recommended to focus its characteristics on the fact that the said shutter (4) also incorporates a radial hole (13), perpendicular to the broad diametral step (12) repeatedly cited, and in turn perpendicular to the valve actuator shaft (7), all this so that in the opening situation shown in the figure 1, said hole (13) is inoperative because it remains facing the valve body (2), specifically towards an area sealed by the seals (5-5 ') and the seal upper (14) or tow-press that assists the shaft (7), while when the valve rotates in the closing direction, such as shown in figure 2, the hole (13) is oriented towards the outlet fitting (11 '), that is to the driving zone devoid of pressure, as previously stated, what it means at least partial emptying of the housing defined within the shutter (4) in such a closing situation, and which in turn prevents that a possible freezing of the water contained therein could cause its breakage, as previously said.
