Abstract
Description
La invención se refiere a un depósito de gas con una membrana exterior y una interior, encerrando la membrana interior una parte de un espacio variable de almacenamiento de gas, así como con un dispositivo para la medición del nivel de llenado del espacio de almacenamiento de gas, que comprende un soporte de sensor y un sensor de nivel de llenado que está fijado en el soporte de sensor, estando previsto en la membrana exterior un orificio de membrana para el dispositivo para la medición del nivel de llenado del espacio de almacenamiento de gas y estando unido el soporte de sensor mediante un elemento de unión al borde del orificio de membrana. The invention relates to a gas tank with an outer and an inner membrane, enclosing the inner membrane a part of a variable gas storage space, as well as with a device for measuring the level of filling of the gas storage space , which comprises a sensor support and a filling level sensor that is fixed in the sensor support, a membrane orifice for the device for measuring the filling level of the gas storage space and in the outer membrane being provided. the sensor support being connected by means of an attachment element to the edge of the membrane hole.
Ha resultado ser imprescindible una medición fiable del nivel de llenado para un servicio seguro y económico de un depósito de gas de este tipo. Las cúpulas de membrana con sensores de nivel de llenado de ultrasonidos que se emplean en la medición convencional del nivel de llenado, como se muestra en el documento EP 1647760 A2 están hechas de acero fino y presentan por lo tanto un peso correspondientemente elevado, habiendo resultado ser poco ventajosos tanto desde el punto de vista de los costes de fabricación, como del transporte y la solicitación de la membrana exterior. Reliable measurement of the filling level has proved to be essential for a safe and economical service of a gas tank of this type. The membrane domes with ultrasonic filling level sensors that are used in the conventional measurement of the filling level, as shown in EP 1647760 A2 are made of stainless steel and therefore have a correspondingly high weight, having resulted to be little advantageous both from the point of view of manufacturing costs, as well as the transport and solicitation of the outer membrane.
En el documento DE 202007007060 U1 se muestra un depósito de gas con un orificio de paso exterior con cierre, que está delimitado por una brida anular y que es adecuado para realizar mediciones del nivel de llenado. No obstante, en este documento no está descrito un dispositivo de medición para la medición del nivel de llenado o un elemento de unión para un dispositivo de medición de este tipo. In DE 202007007060 U1 a gas tank with an outer passage opening with closure is shown, which is delimited by an annular flange and is suitable for filling level measurements. However, this document does not describe a measuring device for measuring the filling level or a connecting element for such a measuring device.
Por lo tanto, el objetivo de la invención es indicar un depósito de gas del tipo indicado al principio para el que no existan los inconvenientes indicados. Therefore, the objective of the invention is to indicate a gas tank of the type indicated at the beginning for which the indicated drawbacks do not exist.
Según la invención esto se consigue porque el elemento de unión está formado por un tubo flexible, estando unido un orificio final del tubo flexible al borde del orificio de membrana y estando fijado en el otro orificio final del tubo flexible el soporte de sensor con el sensor de nivel de llenado, de modo que, durante el uso, la presión de apoyo existente entre la membrana interior y la membrana exterior extiende el tubo flexible encima del orificio de membrana posicionándose de este modo el sensor de nivel de llenado a una distancia del orificio de membrana. According to the invention, this is achieved because the connecting element is formed by a flexible tube, an end hole of the flexible tube being attached to the edge of the membrane hole and the sensor support with the sensor being fixed in the other end hole of the flexible tube of filling level, so that, during use, the support pressure between the inner membrane and the outer membrane extends the flexible tube above the membrane hole thereby positioning the filling level sensor at a distance from the hole of membrane.
El elemento de unión en forma de tubo flexible realizado de este modo se caracteriza por una fabricación económica, que puede hacerse mediante un material flexible sustancialmente más ligero que metal y que puede ser procesado de forma sencilla. Condición previa es la realización estanca a gas y bajo presión del tubo flexible y de sus puntos de unión al orificio de membrana, por un lado, y del soporte de sensor, por otro lado, porque sino no puede mantenerse la presión de apoyo entre la membrana exterior y la interior. También se simplifican sustancialmente el transporte y el montaje, puesto que el tubo flexible realizado según la invención es sustancialmente más ligero que la cúpula de membrana de acero fino convencional. Además, puede mejorarse claramente el comportamiento de la técnica del sonido, puesto que los ruidos son reducidos gracias a la realización en forma de tubo flexible. The flexible tube-shaped connecting element thus made is characterized by an economical manufacture, which can be made by a flexible material substantially lighter than metal and which can be processed simply. A precondition is the gas-tight and low pressure realization of the flexible tube and its points of attachment to the membrane hole, on the one hand, and of the sensor support, on the other hand, because otherwise the support pressure between the outer and inner membrane. Transport and assembly are also substantially simplified, since the flexible tube made according to the invention is substantially lighter than the conventional stainless steel membrane dome. In addition, the behavior of the sound technique can be clearly improved, since the noises are reduced thanks to the embodiment in the form of a flexible tube.
Como era habitual hasta la fecha, el sensor de nivel de llenado puede ser un sensor de ultrasonidos, siendo la longitud del tubo flexible mayor que la altura de la zona muerta del sensor de ultrasonidos. Para la medición de distancia por reflexión de ultrasonidos, esta altura de zona muerta era un impedimento para la medición en cúpulas convencionales de acero fino. En el depósito de gas según la invención, este inconveniente puede superarse en el sentido de que la membrana interior puede llevarse hasta la membrana exterior, puesto que la altura de la zona muerta puede cubrirse mediante el tubo flexible con una adaptación correspondiente de la longitud del tubo flexible. De este modo se aumenta el volumen útil del depósito de gas según la invención. As usual to date, the filling level sensor may be an ultrasonic sensor, the length of the flexible tube being greater than the height of the dead zone of the ultrasonic sensor. For distance measurement by ultrasonic reflection, this dead zone height was an impediment to measurement in conventional stainless steel domes. In the gas tank according to the invention, this drawback can be overcome in the sense that the inner membrane can be carried to the outer membrane, since the height of the dead zone can be covered by the flexible tube with a corresponding adaptation of the length of the flexible tube. This increases the useful volume of the gas tank according to the invention.
No obstante, también pueden realizarse otras formas de realización técnicas de sensores del nivel de llenado, como However, other technical embodiments of filling level sensors, such as
p. ej. sensores ópticos. p. ex. optical sensors
Según una forma de realización de la invención, el tubo flexible puede estar hecho de un material flexible, preferiblemente una lámina de plástico reforzada por tejido, que está realizada de forma tubular a lo largo de un cordón de soldadura longitudinal. En comparación con la conocida cúpula de acero fino, de este modo resulta una simplificación de la fabricación, pudiendo realizarse la misma con una frecuencia de errores sumamente reducida gracias a la sencillez del cordón de soldadura longitudinal. According to an embodiment of the invention, the flexible tube can be made of a flexible material, preferably a woven reinforced plastic sheet, which is made tubularly along a longitudinal welding bead. In comparison with the well-known stainless steel dome, this simplifies the manufacturing process, which can be done with a very low frequency of errors thanks to the simplicity of the longitudinal welding bead.
Otro ahorro de costes resulta si, según otra realización de la invención, el tubo flexible está hecho del mismo material que la membrana exterior. Another cost saving results if, according to another embodiment of the invention, the flexible tube is made of the same material as the outer membrane.
Ha resultado ser muy ventajoso para las propiedades de la técnica del sonido realizar el tubo flexible en una variante de la invención de forma cónica, siendo el diámetro del extremo unido al borde del orificio de membrana mayor que el diámetro del otro extremo unido al soporte de sensor. De este modo se minimizan las reflexiones molestas de las ondas acústicas reflejadas. No obstante, esto no va unido a una restricción a una forma determinada del tubo flexible. El tubo flexible puede estar realizado, p. ej., también de forma cilíndrica. It has proved very advantageous for the properties of the sound technique to make the flexible tube in a conical variant of the invention, the diameter of the end attached to the edge of the membrane orifice being greater than the diameter of the other end attached to the support of sensor. This minimizes the annoying reflections of the reflected sound waves. However, this is not linked to a restriction to a particular shape of the flexible tube. The flexible tube can be made, e.g. eg, also cylindrical.
En cuanto a la técnica de materiales, el borde del orificio de membrana está expuesto durante el uso a una mayor carga mecánica, que en la práctica puede resistirse de la mejor forma si, según otro ejemplo de realización de la invención, el orificio de membrana está realizado de forma circular estando limitado por una brida anular, que está unida a la membrana exterior y si uno de los orificios finales del tubo flexible está fijado mediante un anillo tensor de forma estanca en la brida anular. No obstante, también entra en el alcance de protección otra forma del orificio de membrana de la membrana exterior. As regards the material technique, the edge of the membrane orifice is exposed during use to a greater mechanical load, which in practice can be best resisted if, according to another embodiment of the invention, the membrane orifice It is made in a circular manner being limited by an annular flange, which is attached to the outer membrane and if one of the end holes of the flexible tube is fixed by a tension ring tightly sealed in the annular flange. However, another form of the membrane hole of the outer membrane also enters the scope of protection.
Una fijación sencilla del soporte de sensor en el tubo flexible realizado según la invención se consigue porque el soporte de sensor está formado por una placa circular y porque el sensor de nivel de llenado está dispuesto en el centro de la placa circular. El borde de la placa puede unirse de forma duradera y de forma estanca bajo presión mediante una construcción de brida al extremo alejado de la membrana exterior del tubo flexible. El otro extremo del tubo flexible unido al soporte de sensor puede estar unido correspondientemente a una brida anular, en la que está fijada la placa circular con el sensor de nivel de llenado. No obstante, en el marco de la invención también pueden estar previstas otras formas geométricas del soporte de sensor y otros tipos de unión entre el soporte de sensor y el tubo flexible. A simple fixation of the sensor support in the flexible tube made according to the invention is achieved because the sensor support is formed by a circular plate and because the filling level sensor is arranged in the center of the circular plate. The edge of the plate can be attached durably and tightly under pressure by means of a flange construction at the end away from the outer membrane of the flexible tube. The other end of the flexible tube attached to the sensor support can be correspondingly connected to an annular flange, in which the circular plate is fixed with the filling level sensor. However, other geometric shapes of the sensor support and other types of connection between the sensor support and the flexible tube can also be provided within the framework of the invention.
La realización del tubo flexible según la invención de un material flexible permite una mejora de las propiedades acústicas del dispositivo de medición del nivel de llenado, por lo que se ajusta una mejor reproducibilidad de los resultados de medición. Según otra forma de realización de la invención, una mejora adicional puede prever que la placa circular esté hecha de plástico, que reduzca las molestas reflexiones de sonido durante la medición. The embodiment of the flexible tube according to the invention of a flexible material allows an improvement of the acoustic properties of the filling level measuring device, whereby a better reproducibility of the measurement results is adjusted. According to another embodiment of the invention, a further improvement may provide that the circular plate is made of plastic, which reduces annoying sound reflections during measurement.
A continuación, la invención se explicará detalladamente con ayuda del ejemplo de realización mostrado en los dibujos. Next, the invention will be explained in detail with the aid of the exemplary embodiment shown in the drawings.
