DISPOSITIVO PARA REALIZAR UN INJERTO EN UNA CONDUCCIÓNDEVICE FOR PERFORMING A GRAFT IN A CONDUCTION

Campo de la invenciónfield of invention

La presente invención se refiere a un dispositivo para realizar un injerto en una conducción de tuberías que reduce la cantidad de herramientas, y cantidad de estos elementos necesarios para realizar injertos en los distintos diámetros de tuberías disponibles. El dispositivo objeto de la invención es de aplicación en la industria de la construcción.The present invention refers to a device for making a graft in a pipeline that reduces the number of tools and the number of these elements necessary to make grafts in the different diameters of pipes available. The device object of the invention is applicable in the construction industry.

Antecedentes de la invenciónBackground of the invention

En un sistema o red de tuberías plásticas para la conducción de un fluido en cualquier aplicación (gas, agua potable, agua caliente sanitaria, climatización, riego, aguas residuales, evacuación por depresión, etc..) existen dos elementos básicos principales: las tuberías y sus elementos de unión o accesorios.In a system or network of plastic pipes for the conduction of a fluid in any application (gas, drinking water, sanitary hot water, air conditioning, irrigation, wastewater, evacuation by depression, etc.) there are two main basic elements: the pipes and their joining elements or accessories.

Dentro de los accesorios de unión hay diferentes elementos principales como pueden ser manguitos, codos, tes, portabridas, reducciones, elementos mixtos roscados, injertos, etc. Cada uno de ellos presenta una utilidad dentro de los elementos de conexión. En el caso del injerto, es una pieza diseñada para realizar una "toma” en una red sobre la superficie de la tubería principal de manera directa, sustituyendo el uso de una "T” reducida.Within the union accessories there are different main elements such as sleeves, elbows, tees, flange holders, reductions, mixed threaded elements, grafts, etc. Each of them presents a utility within the connection elements. In the case of the graft, it is a piece designed to make a "take" in a network on the surface of the main pipe directly, replacing the use of a reduced "T".

Actualmente para realizar injertos en conducciones es necesario contar con una pluralidad de utillajes que dependen tanto del diámetro de la tubería principal de la que se desea extraer el ramal que se injerta como del propio diámetro del ramal, lo que se traduce en la existencia de infinidad de elementos para injertos ya que la variabilidad de diámetros en la tubería principal y el ramal y la combinación de ambos da lugar a infinidad de combinaciones.Currently, to carry out grafts in pipes, it is necessary to have a plurality of tools that depend both on the diameter of the main pipe from which the branch to be grafted is to be extracted and on the diameter of the branch itself, which translates into the existence of infinity. of elements for grafts since the variability of diameters in the main pipe and the branch and the combination of both gives rise to an infinite number of combinations.

Las tuberías plásticas se caracterizan, entre otros métodos de unión, por su soldadura por termofusión en todas sus piezas y accesorios. En la actualidad la soldadura socket por termofusión es el sistema más extendido en instalaciones con tuberías plásticas. Consiste en calentar un extremo macho de un tubo y una parte hembra de un accesorio mediante un elemento calefactor denominado matriz y una vez calentado, retirar la matriz y proceder a introducir la parte macho del tubo en la parte hembra del accesorio, de esta manera se funden tubo y accesorio y la soldadura es perfectamente fiable.Plastic pipes are characterized, among other joining methods, by their thermofusion welding in all their parts and accessories. At present, socket welding by thermofusion is the most widespread system in installations with plastic pipes. It consists of heating a male end of a tube and a female part of an accessory by means of a heating element called a matrix and once heated, removing the matrix and proceed to insert the male part of the tube into the female part of the accessory, in this way the tube and accessory are fused and the welding is perfectly reliable.

La soldadura por termofusión presenta una serie de ventajas como son que no precisa de preparaciones iniciales de tubo y accesorio, como pelados, limpiezas, etc.; consigue la absorción de las diferencias dimensionales durante el proceso de soldadura, ya que tubo y pieza se calibran durante su fusión en la matriz, es decir la matriz las conforma dimensionalmente; se hace en un corto período de tiempo, (por ejemplo en un diámetro de 110 mm se puede tardar en hacer una soldadura completa del orden de 2 minutos); es un sistema muy cómodo de ejecutar en diámetros pequeños, de 20 mm a 63 mm lo puede hacer una sola persona manualmente con una herramienta muy sencilla; los accesorios son muy económicos, ya que tanto la maquinaria como los útiles para soldar diámetros hasta 63 mm son muy económicos.Thermofusion welding presents a series of advantages such as that it does not require initial preparation of the tube and accessory, such as stripping, cleaning, etc.; it achieves the absorption of dimensional differences during the welding process, since the tube and piece are calibrated during their fusion in the matrix, that is, the matrix shapes them dimensionally; it is done in a short period of time, (for example in a diameter of 110 mm it can take to make a complete weld of the order of 2 minutes); It is a very comfortable system to execute in small diameters, from 20 mm to 63 mm, it can be done manually by one person with a very simple tool; the accessories are very cheap, since both the machinery and the tools for welding diameters up to 63 mm are very cheap.

Ahora bien, esta soladura también presenta una serie de inconvenientes como son: a partir de diámetro 75 mm hay que realizarlas con un banco de soldadura; es muy complicado hacer soldaduras en diámetros grandes con el tubo colocado de forma aérea; no hay en el mercado accesorios para diámetro mayores de 125 o 160 mm que posibiliten todos los tipos de unión o su precio es muy elevado.However, this welding also presents a series of drawbacks such as: from a diameter of 75 mm it must be carried out with a welding bench; it is very difficult to make welds in large diameters with the tube placed overhead; There are no accessories on the market for diameters greater than 125 or 160 mm that make all types of joints possible or their price is very high.

Por este motivo, para transiciones en diámetros elevados, el sistema de conexiones con injertos con o sin rosca, mediante soldadura socket, permite realizar conexiones de salida o derivaciones en tubos de gran sección ya instalados, fusionando tanto en la superficie exterior de la tubería como en su espesor de pared. En este caso el paso inicial es perforar un tubo de gran diámetro utilizando un taladro con una corona de corte para injertar en el punto en el que se desee la nueva conexión.For this reason, for transitions in large diameters, the connection system with grafts with or without thread, by means of socket welding, allows outlet connections or derivations to be made in large-section pipes already installed, fusing both on the outer surface of the pipe and on the in its wall thickness. In this case, the initial step is to drill a large diameter tube using a drill with a cutting crown to graft at the point where the new connection is desired.

Posteriormente se calienta la parte del tubo insertando la matriz macho específica en el orificio del tubo hasta tocar la parte cóncava con la superficie externa del tubo. De forma paralela se inserta al mismo tiempo el accesorio injerto en la matriz hembra específica. Una vez terminado el calentamiento se inserta la pieza de injerto en el orificio calentado sin girarla. Estas matrices para realizar injertos son específicas y diferentes a todas las empleadas en el resto de los elementos de unión por su característica cóncava y convexa en los extremos.Subsequently, the tube part is heated by inserting the specific male die into the tube hole until the concave part touches the external surface of the tube. In parallel, the graft accessory is inserted into the specific female matrix at the same time. After heating is complete, the graft piece is inserted into the heated hole without turning it. These matrices for grafting are specific and different from all those used in the rest of the joining elements due to their concave and convex characteristics at the ends.

Actualmente, en los injertos que existen en el mercado para soldadura por termofusión, la soldadura es radial en el espesor del tubo principal sobre el que se hace la acometida y como generalmente el espesor de tubo es insuficiente para garantizar esa unión, estas piezas tienen una valona con el radio de curvatura del tubo al que se sueldan, que se fusiona también a la cara externa del tubo, esta fusión no garantiza la estanqueidad del sistema, la función de esta fusión es asegurar un apoyo entre la pieza injerto universal y el elemento de tubo para que en caso de esfuerzos mecánicos que se puedan producir en el ramal de salida conectado al injerto, no sea la soldadura radial la que tenga que soportar dicho esfuerzo, ya que esta soldadura correría el riesgo de romperse.Currently, in the grafts that exist in the market for thermofusion welding, the weld is radial in the thickness of the main tube on which the connection is made and as the thickness of the tube is generally insufficient to guarantee this union, these pieces have a flange with the radius of curvature of the tube to which they are welded, which is it is also fused to the external face of the tube, this fusion does not guarantee the tightness of the system, the function of this fusion is to ensure a support between the universal graft part and the tube element so that in case of mechanical stresses that may occur in the outlet branch connected to the graft, it is not the radial weld that has to support said effort, since this weld would run the risk of breaking.
