OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención se refiere a un dispositivo de acoplamiento o terminal de enlace entre tubos y accesorios, y mas concretamente al acoplamiento que se realiza en el montaje de una válvula sobre una tubería para paso de fluidos.The present invention relates to a coupling device or link terminal between pipes and fittings, and more specifically to the coupling that is made in the assembly of a valve on a pipe for fluid flow.
El objeto de la invención es conseguir un acoplamiento estanco sencillo en su montaje y simple estructuralmente, que según el dispositivo a acoplar puede ir conjunta o sin ella.The object of the invention is to achieve a simple tight coupling in its assembly and structurally simple, which according to the device to be coupled can go together or without it.
ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION
Se conocen numerosos medios y dispositivos para llevar a cabo el acoplamiento de válvulas a tuberías destinadas al paso de fluidos, y en tal sentido puede citarse la solución consistente en una pieza bi-cónica que se dispone sobre la tubería, de manera que por un extremo sobre dicha pieza bi-cónica se sitúa el extremo correspondiente al cuerpo del accesorio, que se acopla a la comentada tubería, mientras que por el otro extremo se dispone una tuerca de apriete que rosca sobre el comentado extremo del cuerpo del accesorio, estableciendo el apriete correspondiente, con la particularidad de que para evitar deformaciones de la tubería en el apriete, se ha previsto que en la zona de acoplamiento se monte un casquillo interno
a la tubería que actúa como un alma interior, que cuando se presiona sobre el bi-cono no se deforma la tubería.Numerous means and devices are known for carrying out the coupling of valves to pipes intended for the passage of fluids, and in this regard the solution consisting of a bi-conical piece that is disposed on the pipe can be cited, so that at one end on said bi-conical piece the end corresponding to the body of the accessory is placed, which is coupled to the said pipe, while at the other end there is a tightening nut that threads on the commented end of the body of the accessory, establishing the tightening corresponding, with the particularity that to prevent deformation of the pipe in the tightening, it is provided that an internal bushing is mounted in the coupling area to the pipe that acts as an inner soul, which when pressed on the bi-cone does not deform the pipe.
Evidentemente, esta solución resulta ventajosa respecto de otros sistemas de acoplamiento conocidos, ya que evita la deformación de la tubería en el acoplamiento. Sin embargo, la realización del sistema o dispositivo de acoplamiento requiere dos piezas independientes, además de la tuerca de apriete correspondiente, ya que por un lado ha de montarse el casquillo en funciones de alma en el interior de la tubería y por otro lado ha de montarse la pieza en forma de bi-cono sobre el exterior de la tubería, lo que supone costes económicos, pérdida de tiempo de montaje, etc.Obviously, this solution is advantageous compared to other known coupling systems, since it prevents deformation of the pipe in the coupling. However, the realization of the coupling system or device requires two independent parts, in addition to the corresponding tightening nut, since on the one hand the bushing has to be mounted as a core in the interior of the pipe and on the other hand it has to The bi-cone shaped part can be mounted on the outside of the pipe, which means economic costs, loss of assembly time, etc.
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El dispositivo que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, en base a una solución sencilla y eficaz, ya que dicho dispositivo presenta la particularidad de que el alma para moldear la deformación de la tubería en el apriete y la pieza de bi-cono es un cuerpo monopieza, por lo que el montaje será mas sencillo, la estructura más simple e incluso se consigue una mejor estanqueidad en el acoplamiento.The device that is recommended has been designed to solve the above-mentioned problem, based on a simple and effective solution, since said device has the peculiarity of the soul to mold the deformation of the pipe in the clamp and the piece of bi -With it is a single piece body, so the assembly will be simpler, the structure simpler and even better sealing is achieved in the coupling.
Mas concretamente, el dispositivo de la invención se constituye a partir de una pieza tubular, que por uno de sus extremos presenta dos alas concéntricas, una interior y otro exterior, entre las que se determina una acanaladura en la que se posiciona precisamente el extremo correspondiente a la tubería en la que se pretende acoplar el accesorio, con la especial particularidad de que el ala o faldón interno es de mayor longitud y
constituye un alma interno para la tubería, alma que tiene por finalidad moldear en la canaladura la deformación de la tubería en el apriete de la tuerca.More specifically, the device of the invention is constituted from a tubular piece, which at one of its ends has two concentric wings, one inside and one outside, between which a groove is determined in which the corresponding end is precisely positioned to the pipe in which the accessory is intended to be coupled, with the special feature that the internal wing or skirt is longer and It is an internal core for the pipe, which aims to mold the deformation of the pipe in the tightening of the nut in the gutter.
La pieza descrita presenta externamente la configuración bi- cónica ya comentada, de manera que sobre la parte cónica externa se posiciona el correspondiente tramo tubular del cuerpo del accesorio, mientras que sobre la tubería y en correspondencia con la parte opuesta va montada la tuerca que por una parte asienta sobre el otro extremo de la pieza, roscando sobre la superficie externa del accesorio, de manera que en el apriete de la tuerca, se establece una fuerza de presión sobre las dos superficies y en definitiva un presionado de dicha pieza sobre la tubería, obligando que ésta se deforme en virtud de la canaladura del alma que constituye el ala o faldón interno de la pieza bi-cónica descrita.The piece described externally presents the biconical configuration already mentioned, so that on the external conical part the corresponding tubular section of the body of the accessory is positioned, while on the pipe and in correspondence with the opposite part the nut is mounted that by one part sits on the other end of the piece, threading on the external surface of the accessory, so that in the tightening of the nut, a pressure force is established on the two surfaces and ultimately a pressing of said piece on the pipe , forcing it to deform by virtue of the groove of the soul that constitutes the inner wing or skirt of the described bi-conical piece.
Por consiguiente, mediante el dispositivo de la invención se consiguen ventajas y prestaciones respecto del sistema descrito en el apartado de antecedentes de la invención, entre las cuales pueden citarse las siguientes:Accordingly, the device of the invention achieves advantages and benefits with respect to the system described in the background section of the invention, among which the following may be mentioned:
- En el montaje únicamente existe una pieza, que es la terminal de enlace, en contra de lo que ocurre en sistema descrito en el estado de la técnica en el que existen dos piezas, la bi-cónica y el alma interior.- In the assembly there is only one piece, which is the link terminal, contrary to what happens in the system described in the state of the art in which there are two pieces, the bi-conical and the inner soul.
- En virtud de la única pieza utilizada en el acoplamiento, únicamente actúa un cierre contra la tubería, eliminando con ello fugas que en ocasiones se originan en los dos cierres que se establecen cuando existe una alma interna y la pieza bi-cónica externa.- By virtue of the only piece used in the coupling, only one closure acts against the pipe, thereby eliminating leaks that sometimes originate in the two closures that are established when there is an internal core and the external bi-conical part.
- Mediante el dispositivo de la invención se consigue siempre un cierre
centrado, al disponerse el tubo en la canaladura establecida en la pieza bi-cónica, lo cual a veces resulta imposible de conseguir cuando las piezas que constituyen el alma y la pieza bi-cónica son independientes.- By means of the device of the invention a closure is always achieved centered, when the tube is arranged in the groove established in the bi-conical piece, which is sometimes impossible to achieve when the pieces that constitute the soul and the bi-conical part are independent.
Por otro lado, en caso de tubos multicapa en los que hay que aislar del contacto con el fluido la parte de corte de la tubería, dicho sector o corte queda totalmente aislado del fluido que contenga en su interior, en virtud lógicamente del faldón o alma establecido interiormente por parte de la pieza terminal de enlace de la invención.On the other hand, in the case of multilayer pipes in which the cutting part of the pipe must be isolated from the contact with the fluid, said sector or cut is totally isolated from the fluid it contains inside, logically by virtue of the skirt or core established internally by the connecting end piece of the invention.
