Object of the invention

La presente invención, según se expresa en el enunciado de esta memoria descriptiva, se refiere a un dispositivo de unión para tubos, en general para conducciones de fluidos, que ha sido concebido para asegurar una perfecta hermeticidad en el acoplamiento entre dos tramos de tubos o elementos correspondientes a una conducción, todo ello en base a unos medios que faciliten el montaje/desmontaje de los propios componentes integrantes de una instalación para conducir fluidos.The present invention, as expressed in the set forth in this specification, refers to a device of union for tubes, in general for fluid conduits, which It has been designed to ensure perfect tightness in the coupling between two sections of tubes or corresponding elements to driving, all based on means that facilitate the assembly / disassembly of the components of a installation to drive fluids.

El objeto de la invención es proporcionar al sector de las conducciones de fluidos una nueva forma de unir tramos de tubos, que resulta hermética cualquiera que sea el régimen de presión, utilizando una junta especial que queda presionada entre los extremos de los tramos de tubos a unir, con la colaboración de una brida perimetral. El dispositivo es aplicable en la unión de cualquier elemento integrante de una instalación de conducción de fluidos (brida, manguito, válvula, codo, etc.).The object of the invention is to provide the fluid conduction sector a new way of joining sections of tubes, which is hermetic whatever the pressure regime, using a special gasket that remains pressed between the ends of the pipe sections to be joined, with the collaboration of a perimeter flange. The device is applicable in the union of any element of an installation of fluid conduction (flange, sleeve, valve, elbow, etc.).

Background of the invention

En ocasiones es necesario y conveniente llevar a cabo el desmontaje de conductos o tubos de conducción de fluidos, para su adaptación, previéndose para ello numerosos tipos de uniones y acoplamientos que permita llevar a cabo ese desmontaje.Sometimes it is necessary and convenient to carry carry out the disassembly of conduits or fluid conduction tubes, for its adaptation, anticipating numerous types of unions and couplings that allow to carry out that disassembly

En tal sentido puede citarse la Patente Europea 94307930 en la que se describe un acoplamiento basado en un manguito que se dispone sobre la zona de unión de dos tubos que se pretenden acoplar, presentando los extremos del manguito un tramo inclinado que se apoya sobre una junta de estanqueidad que queda retenida y presionada mediante una brida con unas conformaciones apropiadas para efectuar la sujeción y presionado de la junta, así como para permitir el posicionado y adecuada fijación del manguito, todo ello complementado con tornillos como elementos de apriete de la brida.In this regard, the European Patent can be cited 94307930 describing a coupling based on a sleeve that is arranged on the junction zone of two pipes that are they intend to couple, presenting the ends of the sleeve a section inclined that rests on a seal that remains retained and pressed by a flange with conformations appropriate to hold and press the joint, as well as to allow the positioning and proper fixation of the sleeve, all complemented with screws as tightening elements of the flange

El acoplamiento referido resulta estructuralmente complejo debido a que incluye un número elevado de componentes, a lo que hay que añadir una forma de configuración especiales que permiten obtener un acoplamiento hermético de los dos tubos a unir, todo lo cual da lugar a que el dispositivo de acoplamiento en sí resulte de elevado costo.The referred coupling is structurally complex because it includes a large number of components, to what to add a special configuration form that allow to obtain a tight coupling of the two tubes to be joined, all of which results in the coupling device itself It is expensive.

Por otro lado, la presión hidráulica en el acoplamiento descrito se transmite a la brida, con los inconvenientes derivados de ello, obligando a realizar la retención entre las partes a unir mediante ranuras anulares practicadas en las embocaduras. Asimismo, en ese acoplamiento la junta trabaja sobre la superficie de los tubos a unir, como consecuencia de que la expansión de dicha junta produce un aplastamiento de sus labios contra superficie externa, todo lo cual adolece de falta de eficacia en su función.On the other hand, the hydraulic pressure in the described coupling is transmitted to the flange, with the inconveniences arising from it, forcing the retention between the parts to be joined by annular grooves made in the mouthpieces Also, in that link the board works on the surface of the tubes to be joined, as a result of the expansion of said joint produces a crush of your lips against external surface, all of which lacks Efficiency in its function.

Además del documento anteriormente referido, puede citarse el Modelo de Utilidad Español n° 261302, que comprende una abrazadera formada por dos partes enfrentadas y fijadas entre sí mediante tornillos de apriete pasantes por orejetas laterales de dichas dos partes de la abrazadera, de manera que entre esta última y el tubo se dispone una junta materializada en un manguito de goma de configuración en "U", con sus extremos acodados hacia el interior, determinando tramos dentados que quedan apoyados en los tubos a unir, mientras que la rama intermedia transversal de tal junta en "U" apoya sobre la superficie interna de la abrazadera.In addition to the aforementioned document, the Spanish Utility Model n ° 261302 can be cited, which it comprises a clamp formed by two facing parts and fixed to each other by means of tightening screws through side lugs of said two parts of the clamp, so that between the latter and the tube there is a materialized joint in a rubber "U" configuration sleeve, with its ends angled inwards, determining toothed sections that are supported by the tubes to be joined, while the branch Transverse intermediate of such a "U" joint rests on the internal surface of the clamp.

La solución descrita en este modelo de utilidad español es válida únicamente cuando los extremos de los tubos a unir son de igual diámetro que el resto del tubo, es decir, tienen que tener un diámetro externo constante para formar una continuidad superficial sin escalonamiento alguno, sin olvidarse que la configuración de la junta es talque requiere un proceso de fabricación complejo y requiriendo la abrazadera estar afectada de un cajeado de ubicación de la propia junta, con lo que el apoyo de dicha abrazadera sobre los tubos se efectúa únicamente a través de los extremos de aquélla.The solution described in this utility model Spanish is valid only when the pipe ends are join are of the same diameter as the rest of the tube, that is, they have have a constant external diameter to form a continuity superficial without any stepping, without forgetting that the board configuration is such that it requires a process of complex manufacturing and requiring the clamp to be affected by a recessed location of the board itself, with which the support of said clamp on the tubes is made only through the ends of that one.

Para solucionar los problemas anteriormente referidos, se concibió el Modelo de Utilidad U 200100841, de la misma solicitante que el modelo que ahora nos ocupa, referente a un dispositivo de unión de elementos o tubos para conducciones de fluidos, basándose en incluir una junta que queda dispuesta en cajeados enfrentados establecidos al efecto en ensanchamientos practicados al efecto en los extremos de los dos elementos a unir, dando lugar a un cajeado frontal y a un resalte perimetral, determinando en el primer caso una cavidad de ubicación para la junta, y en segundo caso para determinar un relieve perimetral sobre el que se posiciona la correspondiente abrazadera o brida de apriete, determinada ésta por dos mitades fijables y apretables entre sí mediante dos simples tornillos laterales.To solve the problems above referred to, the Utility Model U 200100841, of the same applicant as the model that concerns us now, referring to a connecting device of elements or tubes for pipes fluids, based on including a gasket that is arranged in slapped faces set to the effect in widening practiced for this purpose at the ends of the two elements to be joined, giving rise to a frontal recess and a perimeter projection, determining in the first case a location cavity for the joint, and in the second case to determine a perimeter relief on which is positioned the corresponding clamp or flange of tighten, determined by two adjustable and tightened halves each other using two simple side screws.

El dispositivo de unión descrito en este Modelo de Utilidad 200100841, cumple con eficacia su función, pero presenta el inconveniente de que es necesario mecanizar los cajeados en los sistemas de los elementos a acoplar o unir, lo cual supone un encarecimiento, sin olvidarse de que la junta por su configuración resulta difícil de aplicar, de manera tal que a consecuencia del apriete tiende a doblarse y deformarse si no es exacta su ubicación y posicionado de la misma.The joining device described in this Model of Utility 200100841, effectively fulfills its function, but It has the disadvantage that it is necessary to machine the embedded in the systems of the elements to be coupled or joined, which It is an increase, without forgetting that the board for its configuration is difficult to apply, so that consequence of the tightening tends to bend and deform if it is not Exact location and positioning of it.

Description of the invention

El dispositivo de unión objeto de la invención presenta la particularidad de que la junta queda dispuesta entre los extremos enfrentados de las dos expansiones correspondientes a los elementos o tubos a unir, sin necesidad de los cajeados que se requerían con anterioridad, lo que evita que la junta pueda deformarse, evitándose igualmente la necesidad de mecanizar los cajeados, todo lo cual deriva en un ahorro económico considerable.The joining device object of the invention It has the peculiarity that the board is arranged between the opposite ends of the two expansions corresponding to the elements or tubes to be joined, without the need for the recesses previously required, which prevents the board from being able to warp, also avoiding the need to mechanize cajeados, all of which leads to economic savings considerable.

Además, la junta presenta una configuración rectangular con su borde interno de forma angular determinando una configuración bilabial, en tanto que en proximidad al borde opuesto presenta un aro de acero inoxidable que dota a la junta de gran rigidez y por lo tanto de una capacidad indeformable.In addition, the board presents a configuration rectangular with its inner edge angularly determining a bilabial configuration, while in proximity to the opposite edge features a stainless steel ring that gives the board great rigidity and therefore of an undeformable capacity.

La junta en este caso presenta el mismo diámetro que el de las partes extremas y ensanchadas de los dos elementos o tubos a unir, o lo que es lo mismo, de las partes correspondientes a lo que se denomina portabridas, ya que sobre ellas queda situada la brida de apriete correspondiente.The gasket in this case has the same diameter that the one of the extreme and widened parts of the two elements or tubes to be joined, or what is the same, of the corresponding parts to what is called flange holder, since on them it is located the corresponding clamping flange.
