Antecedentes de la invenciónBackground of the invention

En instalaciones del tipo de las anteriormente citadas, es habitual que parte de las mismas esté realizada en polietileno, mientras que otra parte está realizada en metal, de manera que es preciso realizar conexiones entre tubos o tuberías de diferente naturaleza.In installations of the type of the above cited, it is usual that part of them is made in polyethylene, while another part is made of metal, of so that it is necessary to make connections between pipes or pipes of different nature

Para llevar a cabo estas conexiones existen en la práctica diferentes soluciones.To make these connections exist in Practice different solutions.

Una de ellas consiste en utilizar tubos de diferente diámetro, de manera que uno cualquiera de ellos penetra ajustadamente en el interior del otro, lo que supone la existencia de un escalonamiento en la conducción general, que lógicamente determina una pérdida de carga.One of them is to use tubes of different diameter, so that any one of them penetrates tightly inside the other, which implies existence of a staggering in general driving, which logically Determines a loss of charge.

En estos casos y como el polietileno ocupa la posición interior, es decir es el tubo de menos diámetro, se hace preciso disponer a su vez en el interior del mismo de un casquillo rigidizador, lo que supone una estrangulación que aumenta aun mas la pérdida de carga.In these cases and how polyethylene occupies the inner position, that is the tube of less diameter, is made It is necessary to have a bushing inside stiffener, which is a strangulation that increases even more Loss of load

Tratando de obviar este problema es conocida la técnica de abocardar la extremidad libre del tubo metálico, para permitir la utilización de tubos de polietileno con el mismo diámetro interior, pero en este caso se hace imprescindible también la utilización del citado casquillo rigidizador ubicado en el interior del tubo de polietileno, lo que tan solo resuelve el problema de forma parcial, manteniéndose una pérdida de carga importante.Trying to ignore this problem is known the technique of flare the free end of the metal tube, for allow the use of polyethylene pipes with the same inner diameter, but in this case it is also essential the use of said stiffening bushing located in the inside the polyethylene tube, which only solves the Partial problem, maintaining a loss of load important.

Descripción de la invenciónDescription of the invention

El dispositivo de conexión para tubos de distinta naturaleza que la invención propone resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, asegurando un montaje rápido de los tubos componentes y un perfecto acabado superficial interno entre ellos, es decir una perfecta continuidad, que asegura una total inexistencia de pérdida de carga en la unión.The connection device for pipes different nature that the invention proposes solves in a way the problem described above is fully satisfactory, ensuring a quick assembly of the component tubes and a perfect internal surface finish between them, that is a perfect continuity, which ensures a total lack of load loss in the union.

Para ello y de forma mas concreta el dispositivo de conexión que se preconiza se materializa en un accesorio de plástico fabricado por inyección, con un diámetro general coincidente con el del diámetro normalizado del tubo de polietileno, lo que permite la conexión por uno de sus extremos a un tubo de polietileno de longitud indefinida, obtenido por el clásico sistema de extrusión, accesorio de plástico que en su otro extremo incorpora un ensanchamiento, en el que su diámetro interno pasa a ser igual que el diámetro externo del resto de su longitud, y consecuentemente en el que el diámetro interno es coincidente con el diámetro externo del tubo metálico al que ha de acoplarse el tubo de polietileno, lo que permite un enchufamiento ajustado y a presión del elemento metálico y del accesorio, con perfecta continuidad superficial interna entre ambos elementos.For this and more specifically the device of connection that is recommended is embodied in an accessory of plastic manufactured by injection, with a general diameter coinciding with that of the normalized tube diameter polyethylene, which allows connection at one of its ends to a polyethylene tube of indefinite length, obtained by the classic extrusion system, plastic accessory than in its other end incorporates a widening, in which its internal diameter becomes the same as the outer diameter of the rest of its length, and consequently in which the internal diameter is coincident with the outer diameter of the metal tube to which the polyethylene tube, allowing tight fitting and metal element and accessory pressure, with perfect internal surface continuity between both elements.

Por lo demás la fijación mecánica entre el dispositivo y el tubo metálico se llevará a cabo por cualquier sistema convencional, como por ejemplo mediante un casquillo exterior de presión, o cualquier otra solución que se estime conveniente en cada caso.Otherwise the mechanical fixation between the device and the metal tube will be carried out by any conventional system, such as by means of a bushing external pressure, or any other solution estimated convenient in each case.

De esta manera se lleva a cabo la unión entre los dos componentes de distinta naturaleza en ausencia de soldaduras, lo que aumenta la garantía de estanqueidad de la instalación, siendo además la longitud ajustable, dentro de unos límites, a las necesidades de la instalación, y en ausencia de cualquier estrangulación en el paso del fluido, es decir en ausencia de pérdida de carga, como repetidamente se ha dicho.In this way the union between the two components of different nature in the absence of welds, which increases the guarantee of tightness of the installation, the length being also adjustable, within about limits, to the needs of the installation, and in the absence of any strangulation in the passage of the fluid, that is in absence of load loss, as repeatedly stated.
