TITOLO: TUBAZIONE RINFORZATA CONDUTTIVA PER LIQUIDI, SOLUZIONI CHIMICHE, VERNICI, OLI E GAS TITLE: CONDUCTIVE REINFORCED HOSE FOR LIQUIDS, CHEMICAL SOLUTIONS, PAINTS, OILS AND GAS
Forma oggetto del presente trovato una tubazione rinforzata e conduttiva per applicazioni quali pistole a spruzzo per vernici o liquidi chimici, ovvero in tutte quelle applicazioni dove occorre movimentare l'utensile o ottenere raggi di curvatura ridottissimi. The present invention relates to a reinforced and conductive pipe for applications such as spray guns for paints or chemical liquids, or in all those applications where it is necessary to move the tool or to obtain very small bending radii.
Scopo del presente trovato è quello di mettere a disposizione un tubo per il passaggio di liquidi chimici o vernici realizzante una migliorata resistenza all'azione dei solventi ed una minore resistenza alla piegatura, senza schiacciamento in modo da mantenere il passaggio interno del fluido, in quanto il suo utilizzo è favorevole in tutti i casi di movimentazione dell'utensile. The purpose of the present invention is to provide a tube for the passage of chemical liquids or paints which achieves an improved resistance to the action of solvents and a lower resistance to bending, without crushing so as to maintain the internal passage of the fluid, since its use is favorable in all cases of tool handling.
I vantaggi che si ottengono dal presente trovato sono dati dall'aumento di prestazioni tecniche, in quanto si osserva un aumento di oltre il 35% rispetto ai comuni prodotti, esempio della normativa SAE 100 da 1⁄4 di pollice e prestazioni fino al 60% in più rispetto ai diametri da 5/16 di pollice. The advantages obtained from the present invention are given by the increase in technical performance, as an increase of over 35% is observed with respect to common products, for example of the 1⁄4 inch SAE 100 standard and performance up to 60%. more than 5/16 inch diameters.
Aumenta il raggio minimo di piegatura ed aumentano Inoltre, altro vantaggio, il tubo, per come è costituito, presenta una inferiore resistenza alla curvatura, ossia è meno rigido: ciò è dovuto alla mescola termoplastica morbida e la maggior piegatura dovuto all'apposito rinforzo. It increases the minimum bending radius and increases Furthermore, another advantage, the pipe, as it is made, has a lower resistance to bending, that is, it is less rigid: this is due to the soft thermoplastic compound and the greater bending due to the special reinforcement.
Quanto sopra ne migliora l'utilizzo nelle applicazioni quali pistole a spruzzo per vernici o liquidi chimici, ovvero in tutte quelle applicazioni dove occorre movimentare l'utensile. The above improves its use in applications such as spray guns for paints or chemical liquids, or in all those applications where the tool needs to be moved.
Detti scopi e vantaggi sono tutti raggiunti dal tubo per liquidi o soluzioni chimiche o vernici, oggetto del presente trovato, che si caratterizza per quanto previsto nelle sotto riportate rivendicazioni. Said objects and advantages are all achieved by the tube for liquids or chemical solutions or paints, object of the present invention, which is characterized by what is provided in the following claims.
Questa ed altre caratteristiche risulteranno maggiormente evidenziate dalla descrizione seguente di alcune forme di realizzazione illustrate, a puro titolo esemplificativo e non limitativo nelle unite tavole di disegno in cui: This and other characteristics will be more clearly highlighted by the following description of some embodiments illustrated, purely by way of non-limiting example in the accompanying drawing tables in which:
- la figura 1 illustra Una rappresentazione semplificata della tubazione oggetto del trovato, secondo la configurazione di rivestimento dei componenti. Figure 1 illustrates a simplified representation of the pipe according to the invention, according to the configuration of the coating of the components.
- la figura 2 illustra Una ulteriore vista della tubazione in oggetto. Figure 2 illustrates a further view of the pipeline in question.
Con riferimento alla figura 1 si indica con 1 nel suo complesso un tratto di tubazione per utilizzo in applicazioni quali pistole a spruzzo per vernici o liquidi chimici, ovvero in tutte quelle applicazioni dove occorre movimentare lo strumento o l'utensile. With reference to Figure 1, 1 indicates as a whole a section of piping for use in applications such as spray guns for paints or chemical liquids, or in all those applications where the instrument or tool must be moved.
Detta tubazione 1 comprende un'anima più interna 2 in poliammide o poliestere: entro detta anima interna 2 scorre il liquido o il fluido. Said pipe 1 comprises an innermost core 2 made of polyamide or polyester: the liquid or fluid flows within said internal core 2.
Coassiale a detto strato 2, si osserva la presenza di due trecce di rinforzo 3 e 4. Coaxial to said layer 2, the presence of two reinforcing braids 3 and 4 is observed.
Più precisamente le suddette trecce di rinforzo 3 e 4 possono essere: More precisely, the aforementioned reinforcement braids 3 and 4 can be:
- in poliestere - made of polyester
- in fibra di polivinil alcol, fibra nota in termini tecnici con il nome di "kuralon", - in polyvinyl alcohol fiber, a fiber known in technical terms as "kuralon",
- in fibra aramidica, - in aramid fiber,
- in fibra basaltica. - in basaltic fiber.
Le guaine intrecciate 3 e 4 sono incollate sullo strato. The intertwined sheaths 3 and 4 are glued to the layer.
Le caratteristiche delle suddette guaine 3 e 4 sono oltre ad un'ottima tenacità e resilienza, un'elevata resistenza all'abrasione, un elevato modulo di elasticità nonché una buona resistenza agli agenti chimici e fisici. The characteristics of the aforementioned sheaths 3 and 4 are in addition to excellent toughness and resilience, a high resistance to abrasion, a high modulus of elasticity as well as a good resistance to chemical and physical agents.
Il poliestere / aramidica potrà essere impiegato puro o in mista con altre fibre naturali, artificiale o sintetiche. The polyester / aramid can be used pure or mixed with other natural, artificial or synthetic fibers.
Ancora, coassialmente a dette guaine intrecciate di rinforzo 3 e 4 si osserva la presenza di una gabbia 5 metallica di contenimento, calzante dette guaine, formata da filamenti metallici intrecciati allo scopo di realizzare una struttura intrecciata in materiale conduttivo in modo da togliere le cariche elettrostatiche che eventualmente si formano al passaggio del liquido nel tubo stesso; detta struttura metallica 5 funge da gabbia antischiacciamento assicurando al tubo la possibilità di eseguire raggi di piegatura anche strettissimi senza schiacciamento od ovalizzazione del passaggio interno. Furthermore, coaxially with said braided reinforcing sheaths 3 and 4 it is possible to observe the presence of a metal containment cage 5, fitting said sheaths, formed by interwoven metal filaments in order to create a braided structure in conductive material so as to remove the electrostatic charges which eventually form when the liquid passes through the tube itself; said metal structure 5 acts as an anti-crushing cage, ensuring the tube the possibility of making even very narrow bending radii without crushing or ovalizing the internal passage.
A differenza delle guaine trecciate 3 e 4, la suddetta struttura 5 è un trecciato a passo largo per creare rombi di superficie non coperta; come esempio si consideri che la superficie coperta dal filo metallico trecciato è compresa tra il 5% ed il 10% della intera superficie cilindrica definita dalla gabbia 5. Unlike the braided sheaths 3 and 4, the aforementioned structure 5 is a braided line with a large pitch to create diamonds with an uncovered surface; as an example, consider that the surface covered by the braided metal wire is between 5% and 10% of the entire cylindrical surface defined by the cage 5.
Quanto invece alle guaine 3 e 4, la percentuale è molto maggiore; si considera che la superficie di filo (poliestere/aramidico/basaltico) necessario copre una superficie di oltre il 95% della superficie definita dalla guaina (3 o 4) medesima. As for the sheaths 3 and 4, the percentage is much higher; it is considered that the yarn surface (polyester / aramid / basaltic) necessary covers a surface of over 95% of the surface defined by the sheath (3 or 4) itself.
Infine, la tubazione 1 è completata con una guaina 6 in mescola termoplastica o poliuretanica di rivestimento, resistente ad un eventuale contatto con carburanti e solventi esterni. Finally, the pipe 1 is completed with a sheath 6 made of a thermoplastic or polyurethane coating, resistant to any contact with fuels and external solvents.
Al fine di assicurare la continuità elettrica (in fase di scarico) con i corrispettivi raccordi d'estremità si prevede di inserire all'interno della boccola dei raccordi un dente tagliente che in fase di pinzatura incide il rivestimento 6 venendo a contatto con la gabbia metallica 5. In order to ensure electrical continuity (in the unloading phase) with the corresponding end fittings, a sharp tooth is inserted inside the bushing of the fittings which, during the pinching phase, affects the coating 6 coming into contact with the metal cage. 5.
La gabbia metallica realizzata 5 oltre che assicurare raggi estremamente piccoli senza deformare il passaggio interno (ovalizzazione del passaggio interno). The metal cage made 5 as well as ensuring extremely small radii without deforming the internal passage (ovalization of the internal passage).
Ancora, sempre la gabbia metallica 5, rende la tubazione resistente al calpestio (importante quando l'utensile viene movimentato dall'operatore in movimento) Still, still the metal cage 5, makes the pipe resistant to foot traffic (important when the tool is moved by the operator in motion)
