Objeto de la invenciónObject of the invention

Ya existen en el mercado, como es sabido, dispositivos en forma de brida, para permitir el empalme de tuberías con diámetros exteriores iguales. Otras están diseñadas para tuberías con diámetros distintos pero sin embargo las conocidas hasta la actualidad, son bridas de extrema complejidad y coste, lo que encarece la realización en instalaciones cada vez más frecuentes.They already exist in the market, as is known, flange shaped devices, to allow splicing of pipes with equal outside diameters. Others are designed for pipes with different diameters but nevertheless the known to the present, are flanges of extreme complexity and cost, which makes the realization in installations more and more expensive frequent.

Efectivamente, los cada vez más necesarios trabajos de modernización y mantenimiento de las conducciones soterradas de fluidos, obligan a eliminar total o parcialmente tramos de tuberías defectuosas o incapaces de garantizar un servicio útil y seguro, a causa de su envejecimiento y deterioro por las acciones agresivas de agentes internos y externos.Indeed, the increasingly necessary modernization and maintenance of the pipes buried of fluids, force to eliminate totally or partially sections of defective pipes or unable to guarantee a useful and safe service, because of its aging and deterioration due to the aggressive actions of internal and external agents.

En trabajos de sustitución parcial, no será raro encontrarse con la incompatibilidad entre la nueva tubería, elaborada con materiales modernos y de total garantía, y la tubería existente, presentándose dificultades para empalmarlas de forma rápida e inmediata y con bajo coste de realización, ya que los diámetros exteriores de ambas tuberías difícilmente coincidirán.In partial replacement work, it will not be rare encounter incompatibility between the new pipe, made with modern materials and full warranty, and the pipe existing, presenting difficulties to splice them in a way fast and immediate and with low cost of realization, since the outer diameters of both pipes will hardly match.

Esta es la característica esencial de la brida objeto de la presente patente de invención, la cual permitirá, dado su diseño técnico, su adaptación a los extremos de ambas tuberías, aunque sean de diámetro diferente, e incluso tuberías que en superficies lisas, ya que el diseño de la brida permite la fácil y correcta ubicación de los elementos de retención indispensables para esta aplicación.This is the essential characteristic of the flange object of the present invention patent, which will allow, given its technical design, its adaptation to the ends of both pipes, although they are of different diameter, and even pipes than in smooth surfaces, since the flange design allows for easy and correct location of the retention elements essential for This application.

Antecedentes Background

Haciendo una breve referencia al estado de la técnica, deben citarse patentes diversas de bridas estancas para empalmes de tuberías (patentes británicas 1.462.886, 1.528.859 y 1.582.858, modelos de utilidad 235.619, 8600595, 6800609 y 8600639, patentes de invención P8803941 y P0401300), en las cuales se presentan empalmes diversos, con anclajes de diferentes características, pero que no permiten de forma inmediata el empalme de tuberías de diámetro exterior distinto.Making a brief reference to the state of the technique, various patents of watertight flanges must be cited for pipe joints (British patents 1,462,886, 1,528,859 and 1,582,858, utility models 235.619, 8600595, 6800609 and 8600639, invention patents P8803941 and P0401300), in which they present diverse splices, with anchors of different features, but that do not allow splicing immediately of pipes of different outside diameter.

La realización que se propone en la presente patente de invención, permite realizar los empalmes que se han citado anteriormente con la total garantía de una total estanqueidad y de que ninguna de las dos tuberías pueda escaparse de la acción de la brida a causa de una sobrepresión interior o de una acción exterior de sobretensión, todo ello gracias a los diversos elementos que componen la brida.The embodiment proposed herein invention patent, allows to realize the joints that have been cited above with the total guarantee of a total tightness and that neither pipe can escape  the action of the flange due to an internal overpressure or a external overvoltage action, all thanks to the various elements that make up the flange.

Esencialmente, la brida estanca para empalme de tuberías de diámetro exterior distinto y extremos lisos, objeto de esta invención, se caracteriza por estar constituida por un cuerpo anular cilíndrico, elaborado en material elástico, que constituye el elemento de estanqueidad de la brida y que presenta como característica esencial que los relieves interiores de sus extremos, que permiten conferir al conjunto la estanqueidad requerida, son de diámetro distinto, lo que permitirá su fácil y correcto acoplamiento sobre la cara exterior de las tuberías a empalmar de diámetro, externo, asimismo diferente. Los diámetros internos del cuerpo anular y de las dos tuberías estarán, por ello, debidamente relacionadas.Essentially, the tight flange for splicing of pipes of different outside diameter and smooth ends, object of This invention is characterized by being constituted by a body cylindrical ring, made of elastic material, which constitutes the sealing element of the flange and presenting as essential feature that the interior reliefs of its ends, that allow to confer to the set the required tightness, are of different diameter, which will allow its easy and correct coupling on the outer face of the pipes to be spliced of diameter, external, also different. The internal diameters of annular body and the two pipes will therefore be duly related.

Se completa la brida con los elementos ubicados junto al cuerpo anular cilíndrico, para permitir y garantizar su perfecta sujeción y anclaje sobre la superficie exterior de la brida y el cuerpo envolvente de la brida propiamente dicha, cilíndrico y provisto de los elementos característicos de apriete, tal como se describirá a continuación.The flange is completed with the elements located next to the cylindrical annular body, to allow and guarantee its perfect hold and anchor on the outer surface of the flange and the body of the flange itself, cylindrical and provided with the characteristic elements of tightening, as will be described below.

Optionally, between the outer rim (2) and the body void (1), may be arranged, if deemed convenient and with the purpose of increasing the strength of the assembly, a cover cylindrical metal, similar to outer rim, cover not drawn in the example represented in the figures.

En la representación gráfica, se observa la ubicación del aro de retención y anclaje (3), ya conocido, provisto de una serie de dobleces (4) en su perímetro, que determinan un conjunto sucesivo de vértices (5) que se apoyarán y fijarán sobre la cara exterior del extremo de la tubería (6), la de diámetro mayor de las que deben empalmarse, en un caso vértices que actuarían en el momento en que esta tubería se desplazase accidentalmente en sentido axial hacia el exterior de la brida, clavándose sobre la superficie de la tubería (6) e impidiendo su desplazamiento.In the graphic representation, the location of the retaining and anchoring ring (3), already known, provided of a series of folds (4) in its perimeter, which determine a successive set of vertices (5) that will be supported and fixed on the outer face of the end of the pipe (6), the one with the largest diameter of those that must be spliced, in one case vertices that would act in the moment this pipe accidentally moved in axial direction towards the outside of the flange, digging into the surface of the pipe (6) and preventing its displacement.

En lo que se refiere al otro extremo de la brida, se observa el mayor grosor de la embocadura del cuerpo anular (1), de modo que podrá adaptarse de inmediato sobre la superficie exterior de la tubería (7), de diámetro menor en este otro caso. Asimismo, la acción de los vértices (5) es la misma en este extremo de la tubería (7).As far as the other end of the flange is concerned, the greater thickness of the mouth of the annular body (1) is observed, so that it can adapt immediately on the surface outside of the pipe (7), of smaller diameter in this other case. Also, the action of the vertices (5) is the same at this end. of the pipe (7).

Ambas embocaduras o extremos del cuerpo anular cilíndrico (1), poseen un labio, configurado hacia adentro y de paredes sensiblemente inclinadas, siendo el labio (8a), correspondiente a la tubería (6) de diámetro exterior menor, mientras que el labio del otro extremo (8b), es de diámetro mayor, para poder adaptarse, como antes se ha indicado, sobre la respectiva cara externa de la tubería de menor diámetro. Se consigue pues la unión enrasando las extremidades de las tuberías por testa.Both mouths or ends of the annular body cylindrical (1), they have a lip, configured inward and of substantially inclined walls, the lip (8a) being, corresponding to the pipe (6) of smaller outside diameter, while the lip of the other end (8b) is larger in diameter, to adapt, as indicated above, on the respective external face of the smaller diameter pipe. I know get the connection by flush the ends of the pipes by testa.

El contorno interno de los labios extremos (8a) y (8b) del cuerpo anular (1) se completa con las oquedades tóricas (9) donde, opcionalmente podrán ubicarse sendos resortes espirales, no representados en los dibujos, para transmisión de una presión adicional en según qué exigencias de empalme.The internal contour of the extreme lips (8a) and (8b) of the annular body (1) is completed with the O-rings (9) where, optionally, two spiral springs may be located, not shown in the drawings, for transmission of a pressure additional according to what splice requirements.

La llanta exterior (2), así como los anillos de retención y anclaje (3), presentarán una discontinuidad en su perímetro circular, con el fin de permitir su adaptación al diámetro exterior de la respectiva tubería a empalmar. Por el contrario, el cuerpo anular cilíndrico (1), será, por razones evidentes, uniforme y continuo.The outer rim (2), as well as the rings of retention and anchoring (3), will present a discontinuity in their circular perimeter, in order to allow its adaptation to outer diameter of the respective pipe to be spliced.
