El objeto de la invención es proporcionar al mercado y público en general, una abrazadera que repara uniones de tuberías con fugas, sin necesidad de tener que cortar el suministro del fluido que circula a través de las mismas. The object of the invention is to provide the market and the general public with a clamp that repairs leaking pipe joints, without having to cut off the supply of the fluid flowing through them.

Así pues, el objeto de la invención es proporcionar unos medios para llevar a cabo 15 reparaciones permanentes ante fugas en tuberías de una forma rápida y sencilla. Thus, the object of the invention is to provide means for carrying out permanent repairs to leaks in pipes quickly and easily.

BACKGROUND OF THE INVENTION

20 twenty

Como es sabido, el polietileno es un producto derivado de un hidrocarburo que se considera amigable con el medio ambiente y no se hincha fácilmente ni se disuelve en los disolventes más comunes, por lo que dichas características hacen del polietileno un material ideal para ser utilizado en la construcción de tuberías. As is known, polyethylene is a product derived from a hydrocarbon that is considered environmentally friendly and does not swell easily or dissolve in the most common solvents, so these characteristics make polyethylene an ideal material to be used in Pipeline construction

Pues bien, como consecuencia de lo anteriormente expuesto, el uso de las tuberías de polietileno en la conducción de fluidos se ha extendido exponencialmente en las últimas décadas, ya que ofrecen características deseables, tales como bajo peso, resistencia a la abrasión, resistencia a la corrosión, alta resistencia al impacto, y una flexibilidad superior. Well, as a result of the above, the use of polyethylene pipes in fluid conduction has expanded exponentially in recent decades, as they offer desirable characteristics, such as low weight, abrasion resistance, resistance to corrosion, high impact resistance, and superior flexibility.

30 30

La unión de los tubos de polietileno se suele realizar de dos formas diferentes, bien por soldadura a tope, es decir, calentando, presionando y soldando los extremos de los tubos a unir, o bien mediante el uso de manguitos electrosoldables que se introducen en los extremos de los tubos a unir y que mediante una corriente eléctrica se calientan los dos lados y el manguito, soldándolos con el exterior de los tubos. 35 The joining of the polyethylene pipes is usually carried out in two different ways, either by butt welding, that is, by heating, pressing and welding the ends of the tubes to be joined, or by using electroweldable sleeves that are introduced into the ends of the tubes to be joined and that by means of an electric current the two sides and the sleeve are heated, welding them with the outside of the tubes. 35

Pues bien, en los puntos de unión de los tubos de polietileno a veces se producen fugas que pueden estar motivadas por determinadas causas, como puede ser un calentamiento insuficiente que no ha permitido una soldadura eficaz, o bien por el uso de manguitos electrosoldables defectuosos, etc. 5 Well, at the junction points of the polyethylene pipes there are sometimes leaks that can be caused by certain causes, such as insufficient heating that has not allowed an effective welding, or by the use of defective electro-weldable sleeves, etc. 5

Para reparar esas fugas, actualmente la reparación se lleva a cabo mediante una única posibilidad que es la de cortar el tubo en el punto de la unión, para su posterior reparación, lo que supone la necesidad de tener que interrumpir la conducción del fluido de que se trate, con los problemas que ello puede ocasionar. 10 To repair these leaks, the repair is currently carried out by means of a single possibility that is to cut the tube at the point of the joint, for its subsequent repair, which implies the need to have to interrupt the conduction of the fluid from which be concerned, with the problems that this can cause. 10

Si bien en el modelo de utilidad 200400878 del que es titular el propio solicitante se describe una abrazadera de reparación para tuberías de polietileno, sin embargo este dispositivo está previsto para la reparación de un tubo de polietileno liso, y no en lo que es la zona o punto de unión de dos tramos de tubería. Es decir, en dicho modelo de utilizad no es posible el 15 uso de la abrazadera descrita en los puntos de unión de las tuberías de polietileno que han sido conectadas mediante manguitos electrosoldables o mediante soldadura a tope. Although in the utility model 200400878 of which the applicant himself owns a repair clamp for polyethylene pipes is described, however this device is intended for the repair of a smooth polyethylene tube, and not in what is the area or junction point of two sections of pipe. That is, in said use model it is not possible to use the clamp described at the junction points of the polyethylene pipes that have been connected by electroweldable sleeves or by butt welding.

DESCRIPTION OF THE INVENTION 20

El dispositivo que se preconiza resuelve de forma plenamente satisfactoria la problemática anteriormente expuesta, en base a una estructura sencilla pero sumamente eficaz, estando prevista para reparar fugas que se producen en los puntos de unión de dos tramos de tubería de polietileno. 25 The recommended device solves in a fully satisfactory manner the above-mentioned problem, based on a simple but highly effective structure, being planned to repair leaks that occur at the junction points of two sections of polyethylene pipe. 25

Así pues, mediante la abrazadera de la invención se pueden eliminar fugas de fluidos que se suceden en los puntos de unión de tuberías de polietileno conectadas con manguitos electrosoldables o mediante soldadura a tope, y todo ello sin tener que cortar el tubo o tener que interrumpir la conducción del fluido. 30 Thus, by means of the clamp of the invention fluid leaks that occur at the junction points of polyethylene pipes connected with electroweldable sleeves or by butt welding can be eliminated, and all this without having to cut the tube or have to interrupt the conduction of the fluid. 30

Para ello, y de forma más concreta, la abrazadera de la invención está constituida por un cuerpo formado por dos mitades esencialmente semi-cilíndricas que se disponen directamente sobre la zona de unión de los dos tramos de tubería a sellar, de manera que esas dos mitades se unen y fijan entre sí mediante tornillos pasantes por orejetas laterales 35 To do this, and more specifically, the clamp of the invention is constituted by a body formed by two essentially semi-cylindrical halves that are arranged directly on the area of union of the two sections of pipe to be sealed, so that those two halves are joined and fixed together by means of through screws through lateral lugs 35

de los bordes laterales de cada mitad, al objeto de llevar a cabo un apriete y presionado del cuerpo constitutivo de la abrazadera sobre la zona de unión de la tubería a reparar, con la especial particularidad de que esas dos mitades se complementan internamente con respectivas juntas de hermeticidad, con un dentado interno que permite una adaptación hermética de ambas mitades que constituyen el cuerpo de la abrazadera sobre la superficie 5 de la tubería en la que se aplica la abrazadera en cuestión. of the lateral edges of each half, in order to carry out a tightening and pressing of the constituent body of the clamp on the area of union of the pipe to be repaired, with the special feature that these two halves are internally complemented with respective seals of tightness, with an internal toothing that allows a hermetic adaptation of both halves that constitute the body of the clamp on the surface 5 of the pipe in which the clamp in question is applied.

Como se ha dicho con anterioridad, la unión de las dos mitades se realiza a través de tronillos pasante por orejetas con orificios enfrentables y emergentes lateralmente de cada mitad, de manera que esos tornillos se complementan con respectivas tuercas de apriete y 10 junta intermedia de estanqueidad. As mentioned previously, the joining of the two halves is done through threads through lugs with facing holes and emerging laterally from each half, so that these screws are complemented with respective clamping nuts and 10 intermediate seal .

Cabe decir que las partes extremas de las mitades presentan unos mordientes de bloqueo que adoptan la forma de un tronco de cono. It should be said that the extreme parts of the halves have blocking mordants that take the form of a cone trunk.

15 fifteen

Mediante esta abrazadera se consigue una hermeticidad total y completa sobre la zona de unión de dos tramos de tubo de polietileno de manera que la abrazadera internamente presenta un diámetro ligeramente mayor que el de los tubos a los que se acopla, permitiendo incluir en su seno los elementos sobresalientes en la fijación de dos tuberías sin que éstos estorben en su acoplamiento, siendo las citadas juntas, de menor diámetro, las 20 que se adaptan por deformación elástica de las mismas al diámetro exacto de las tuberías, consiguiéndose así un cierre totalmente hermético. Through this clamp, a total and complete tightness is achieved on the joining area of two sections of polyethylene tube so that the clamp internally has a diameter slightly larger than that of the tubes to which it is attached, allowing it to include the Outstanding elements in the fixation of two pipes without clogging them in their coupling, said joints being of smaller diameter, the 20 that are adapted by elastic deformation of the same to the exact diameter of the pipes, thus achieving a completely hermetic seal.
