DISPOSITIVO DI CONNESSIONE PER TUBI CONNECTION DEVICE FOR PIPES
DESCRIZIONE DELL'INVENZIONE DESCRIPTION OF THE INVENTION
La presente invenzione s'inquadra nei settori dell’idraulica e della termo-tecnica e si riferisce ad un dispositivo di connessione per tubi particolarmente adatto a realizzare impianti ed anche condutture per i pavimenti radianti. The present invention falls within the fields of hydraulics and thermo-technology and refers to a connection device for pipes particularly suitable for making systems and also pipes for radiant floors.
Il dispositivo oggetto dell’invenzione comprende la sagomatura delle estremità di tubi da collegare e connettere. Tali tubi, ad esempio, sono realizzati in rame od altro materiale malleabile e con un eventuale strato esterno sintetico di rivestimento. Il dispositivo comprende collettori, nippli, giunti, collari e tenute destinati a cooperare con dette sagomature per realizzare il collegamento e le connessioni dei tubi. The device object of the invention comprises the shaping of the ends of pipes to be connected and connected. Such pipes, for example, are made of copper or other malleable material and with a possible external synthetic coating layer. The device comprises manifolds, nipples, joints, collars and seals intended to cooperate with said shapes to make the connection and connections of the pipes.
Le connessioni di tipo noto in genere prevedono collettori e specifici raccordi per tubi che, una volta fissati, provocano un restringimento della sezione interna riducendo la portata e creando perdite di carico sull’impianto. Known connections generally include manifolds and specific pipe fittings which, once fixed, cause a narrowing of the internal section, reducing the flow rate and creating pressure drops on the system.
Altre connessioni note sono molto complesse da realizzare o richiedono elementi molto costosi e, comunque, anch’esse sono sovente affette da restringimento del lume. Other known connections are very complex to make or require very expensive elements and, in any case, they too are often affected by lumen narrowing.
Inoltre molte delle connessioni di tipo noto non sono in grado di assicurare la tenuta per tutto il tempo necessario e, a causa di vibrazioni, corrosioni ed usura, possono causare perdite che, particolarmente nel caso di installazioni a pavimento o inglobate nella muratura, possono avere conseguenze molto onerose. Furthermore, many of the known connections are not able to ensure the seal for as long as necessary and, due to vibrations, corrosion and wear, can cause leaks which, particularly in the case of floor installations or embedded in the masonry, may have very onerous consequences.
Uno scopo della presente invenzione à ̈ quello di proporre un dispositivo di connessione per tubi senza restringimenti. An object of the present invention is to propose a connection device for pipes without restriction.
Altro scopo à ̈ di proporre un dispositivo per realizzare rapidamente e facilmente connessioni tra tubi, valvole, apparati, anche in cantiere ed in fase di messa in opera. Ulteriore scopo à ̈ di proporre un dispositivo in grado di realizzare connessioni e giunzioni sicure e durature. Another purpose is to propose a device for quickly and easily making connections between pipes, valves, apparatuses, even on site and during the installation phase. A further aim is to propose a device capable of making safe and long-lasting connections and junctions.
Altro scopo à ̈ di proporre un dispositivo particolarmente adatto per realizzare pavimenti radianti e circuiti inglobati nella muratura in genere. Another purpose is to propose a device particularly suitable for making radiant floors and circuits incorporated in the masonry in general.
Ulteriore scopo à ̈ di proporre un dispositivo componibile per realizzare connessioni modulari. A further aim is to propose a modular device for making modular connections.

Con riferimento alle figure da 1 a 37, con 1 viene indicato il dispositivo di connessione per tubi 2, oggetto della presente invenzione, in grado di realizzare i collegamenti e le interconnessioni tra i tubi stessi, tra tali tubi ed un impianto di alimentazione, valvole e strumenti e simili, in impianti idraulici anche di tipo per riscaldamento a pavimento. With reference to Figures 1 to 37, 1 indicates the connection device for pipes 2, object of the present invention, capable of making the connections and interconnections between the pipes themselves, between these pipes and a supply system, valves and tools and the like, in plumbing systems, including those for underfloor heating.
Le estremità da collegare di tali tubi 2 comprendono rispettive sagomature 3. The ends to be connected of these pipes 2 comprise respective shapes 3.
Ciascuna sagomatura 3 Ã ̈ realizzata in corpo unico con il rispettivo tubo 2 e presenta una porzione cilindrica 4 avente diametro interno DD superiore al diametro interno D del corrispondente tubo. Each shaping 3 is made in a single body with the respective tube 2 and has a cylindrical portion 4 having an internal diameter DD greater than the internal diameter D of the corresponding tube.
Preferibilmente i tubi 2 sono a doppio strato in cui il primo strato interno à ̈ composto da un tubo preferibilmente in rame avente spessore 0,3 mm, e lo strato di rivestimento esterno à ̈ di materiale plastico isolante avente spessore 1,7 mm saldamente aderente al tubo in rame. In alternativa lo strato interno del tubo può essere in leghe di rame o altri materiali deformabili plasticamente. Preferably the pipes 2 are double-layered in which the first internal layer is composed of a preferably copper pipe having a thickness of 0.3 mm, and the external coating layer is of insulating plastic material having a thickness of 1.7 mm, firmly adhering to the copper tube. Alternatively, the inner layer of the tube can be made of copper alloys or other plastically deformable materials.
La sagomatura 3 terminale di ciascun tubo à ̈ realizza tramite una deformazione plastica e presenta tre porzioni: The 3 terminal shaping of each tube is achieved by means of a plastic deformation and has three portions:
- una prima porzione troncoconica 10 il cui lume interno ha basi minore e maggiore di diametro uguale rispettivamente al diametro interno D del corrispondente tubo 2 ed al diametro interno DD della corrispondente porzione cilindrica 4 per raccordarli, ove l’angolo solido di detta prima porzione troncoconica 10 à ̈ compreso tra circa 20° e circa 45° e preferibilmente à ̈ di circa 30°. Tale valore di circa 30° à ̈ stato determinato per poter ottener la deformazione senza creare rotture nel tubo in rame ed anche con l’obiettivo di ridurre per quanto possibile gli sforzi necessari per ottenere la deformazione interna del diametro del tubo; - a first frusto-conical portion 10 whose internal lumen has smaller and larger bases of diameter equal respectively to the internal diameter D of the corresponding tube 2 and to the internal diameter DD of the corresponding cylindrical portion 4 to connect them, where the solid angle of said first portion truncated cone 10 is between about 20 ° and about 45 ° and preferably is about 30 °. This value of about 30 ° was determined to be able to obtain the deformation without creating cracks in the copper pipe and also with the aim of reducing as much as possible the efforts necessary to obtain the internal deformation of the pipe diameter;
- la porzione cilindrica 4 perfettamente cilindrica ed avente una certa lunghezza per alloggiare uno speciale mezzo a nipplo recante gli elementi di tenuta; - the cylindrical portion 4 perfectly cylindrical and having a certain length to house a special nipple means carrying the sealing elements;

La seconda porzione troncoconica 11 realizza un importantissimo smusso che serve, in fase di accoppiamento con altri elementi del dispositivo dotati di guarnizioni di tenuta, a facilitare tale accoppiamento ed a proteggere gli elementi di tenuta da eventuali danneggiamenti. The second frusto-conical portion 11 forms a very important chamfer which serves, during the coupling phase with other elements of the device equipped with sealing gaskets, to facilitate this coupling and to protect the sealing elements from possible damage.
Il dispositivo comprende un mezzo a nipplo 5 una cui estremità à ̈ dotata di un rispettivo mezzo di collegamento 30 tubolare di forma approssimativamente cilindrica. Tale mezzo di collegamento può essere relativamente corto presentando, ad esempio, uno sviluppo longitudinale del medesimo ordine di grandezza del proprio raggio massimo. The device comprises a nipple means 5, one end of which is provided with a respective tubular connection means 30 having an approximately cylindrical shape.
