"RACCORDO PER LA GIUNZIONE DI TUBAZIONI IN GENERE" "FITTING FOR THE JOINT OF PIPES IN GENERAL"
DESCRIZIONE DESCRIPTION
Il presente trovato si riferisce ad un raccordo per la giunzione di tubazioni in genere. The present invention refers to a fitting for joining pipes in general.
Come à ̈ noto, in molti campi di applicazione industriale, vengono utilizzati dei raccordi per applicazioni a pressioni medio-basse, cioà ̈ nell'ordine di 200 bar massimi, che sono realizzati con il principio del cosiddetto "anello tagliato" . As is known, in many fields of industrial application, fittings are used for applications at medium-low pressures, ie in the order of 200 bar maximum, which are made with the so-called "cut ring" principle.
Con le soluzioni della tecnica nota si ha che, nel caso in cui si debba procedere alla connessione tra due raccordi disassati, Ã ̈ necessario utilizzare tubi metallici rigidi che debbono essere direttamente sagomati durante le operazioni di montaggio e messa in opera dell<1>impianto. With the solutions of the known technique, it is necessary to use rigid metal pipes that must be directly shaped during the assembly and installation operations of the system, in the case in which it is necessary to proceed with the connection between two misaligned fittings. .
Questi tipi di raccordo creano inevitabilmente una discontinuità in una tubazione e sono dei punti critici dove possono manifestarsi perdite e gocciolamenti, soprattutto quando la tubazione non à ̈ perfettamente stabile o à ̈ sottoposta a vibrazioni e a colpi di ariete . These types of fittings inevitably create a discontinuity in a pipe and are critical points where leaks and dripping can occur, especially when the pipe is not perfectly stable or is subjected to vibrations and water hammers.
Con la soluzione della tecnica nota, si ha quindi la necessità di utilizzare, nella realizzazione di giunzioni fra tubazioni, staffe di fissaggio che vengono posizionate a distanza prefissata dai raccordi stessi, in modo da irrigidire la giunzione. With the solution of the known art, it is therefore necessary to use, in making joints between pipes, fixing brackets which are positioned at a predetermined distance from the fittings themselves, so as to stiffen the joint.
Il compito che si propone il trovato à ̈ appunto quello di risolvere il problema sopra esposto, realizzando un raccordo per la giunzione di tubazioni in genere, che dia la possibilità di realizzare la connessione in modo particolarmente semplice e riducendo al minimo l'utilizzazione di staffe di supporto. The aim of the invention is precisely that of solving the problem described above, creating a fitting for joining pipes in general, which gives the possibility of making the connection in a particularly simple way and minimizing the use of brackets. support.
Nell·'ambito del compito sopra esposto, uno scopo particolare del trovato à ̈ quello di realizzare un raccordo che, durante le operazioni di montaggio, non crei sollecitazioni torsionali sulle parti da connettere, contribuendo così alla continuità della connessione. Within the scope of the aim described above, a particular object of the invention is to provide a joint which, during the assembly operations, does not create torsional stresses on the parts to be connected, thus contributing to the continuity of the connection.
Ancora uno scopo del presente trovato à ̈ quello di realizzare un raccordo che consenta un abbattimento dei tempi e dei costi relativi alle operazioni di preparazione dei tubi, riducendo inoltre la rigidità strutturale del collegamento raccordo-tubo per effetto dell'assorbimento delle vibrazioni direttamente da parte del tubo di connessione . Another object of the present invention is to provide a fitting which allows a reduction in the times and costs relating to the operations for preparing the tubes, also reducing the structural rigidity of the fitting-tube connection due to the absorption of vibrations directly by of the connection pipe.
Non ultimo scopo del presente trovato à ̈ quello di realizzare un raccordo per la giunzione di tubazioni in genere che, per le sue peculiari caratteristiche realizzative, sia in grado di dare le più ampie garanzie di affidabilità e sicurezza nell 'uso. Not least object of the present invention is to provide a fitting for joining pipes in general which, due to its particular constructive characteristics, is capable of giving the greatest guarantees of reliability and safety in use.
Il compito sopra esposto, nonché gli scopi accennati ed altri che meglio appariranno in seguito, vengono raggiunti da un raccordo per la giunzione di tubazioni in genere, secondo il trovato, caratterizzato dal fatto di comprendere un corpo dì raccordo definente un corpo centrale dotato di imbocco inseribile in un tubo flessibile retinato e di una bussola serrabile su detto tubo flessibile, a detto corpo centrale essendo girevolmente connesso a tenuta un adattatore presentante un codolo accoppiabile, con un raccordo fisso ad anello tagliato. The aforementioned aim, as well as the aforementioned purposes and others which will appear better later, are achieved by a fitting for joining pipes in general, according to the invention, characterized in that it comprises a fitting body defining a central body provided an inlet which can be inserted into a meshed flexible tube and of a bush which can be tightened on said flexible tube, an adapter having a coupled tang with a fixed cut ring fitting being rotatably connected to said central body.
Ulteriori caratteristiche e vantaggi risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita, ma non esclusiva, di un raccordo per la giunzione di tubazioni in genere, illustrata a titolo indicativo e non limitativo con l'ausilio degli uniti disegni in cui : Further characteristics and advantages will become clearer from the description of a preferred but not exclusive embodiment of a fitting for joining pipes in general, illustrated by way of non-limiting example with the aid of the accompanying drawings in which:
la figura 1 rappresenta schematicamente in sezione il corpo di raccordo; Figure 1 is a schematic sectional view of the connecting body;
la figura 2 evidenzia il corpo di raccordo connesso all'estremità di un tubo flessibile; e figure 2 shows the fitting body connected to the end of a flexible pipe; And
la figura 3 rappresenta in scala ingrandita e parzialmente in sezione il particolare della connessione del corpo di raccordo ad un raccordo fisso . Figure 3 is an enlarged and partially sectional view of the detail of the connection of the fitting body to a fixed fitting.
Con riferimento alle citate figure, il raccordo per la giunzione di tubazioni in genere, secondo il trovato, comprende un corpo di raccordo, indicato globalmente con il numero di riferimento 1, il quale presenta un corpo centrale 2 che presenta una flangia poligonale 3 per l'impegno con un utensile ed à ̈ dotato di un imbocco 4 con resche anti-sfilamento 4a sul quale viene preventivamente connesso il tubo flessibile retinato 5 e successivamente serrata una bussola 6 con dentatura interna 6a che viene cianfrinata con una pressa oleodinamica, in grado di conferire la deformazione permanente necessaria al mantenimento del tubo. With reference to the aforementioned figures, the fitting for joining pipes in general, according to the invention, comprises a fitting body, generally indicated with the reference number 1, which has a central body 2 which has a polygonal flange 3 for the engagement with a tool and is equipped with an inlet 4 with anti-slipping barb 4a on which the braided flexible tube 5 is previously connected and subsequently a bush 6 with internal toothing 6a is tightened which is caulked with an oleodynamic press, capable of give the permanent deformation necessary to maintain the pipe.
Al corpo centrale 2 risulta connesso un adattatore 10 il quale presenta una porzione a bicchiere 11 con flangiatura poligonale 12 che risulta girevolmente associato a tenuta con una porzione cilindrica 7 del corpo centrale 2. An adapter 10 is connected to the central body 2 which has a cup portion 11 with polygonal flanging 12 which is rotatably associated in a seal with a cylindrical portion 7 of the central body 2.
In particolare, viene previsto un filo metallico 13 inseribile in corrispondenti gole 14 definite sul corpo centrale e sulla superficie interna della porzione a bicchiere in modo da impedire lo sfilamento meccanico, mentre la tenuta fluidodinamica viene ottenuta mediante mezzi di tenuta costituiti da un doppio OR 15 che à ̈ posto in sedi anulari 16 definite sul corpo centrale, così da avere un impegno di tenuta sulla superficie interna della porzione a bicchiere. In particular, a metal wire 13 is provided which can be inserted into corresponding grooves 14 defined on the central body and on the internal surface of the cup portion so as to prevent mechanical extraction, while the fluid-dynamic seal is obtained by means of sealing means consisting of a double OR 15 which is placed in annular seats 16 defined on the central body, so as to have a sealing engagement on the internal surface of the cup portion.
L'adattatore 10 Ã ̈ dotato di un codolo 20 a conformazione liscia che definisce una rientranza anulare 21 per l'impegno con l'anello tagliato 22 a sezione troncoconica che viene serrato da porzione troncoconica del bullone di serraggio 23 connesso ad un raccordo fisso 24 che, ad esempio, Ã ̈ del tipo raccordo a parete. The adapter 10 is equipped with a smooth-shaped shank 20 which defines an annular recess 21 for engagement with the truncated-conical section cut ring 22 which is tightened by the truncated-conical portion of the tightening bolt 23 connected to a fixed fitting 24 which, for example, is of the wall connection type.
L'anello 22 agisce su un elemento di tenuta 25 che viene pressato al serraggio dell'anello tagliato, tramite una rondella 26. The ring 22 acts on a sealing element 25 which is pressed when the cut ring is tightened by means of a washer 26.
Con la disposizione descritta si ha che anche in caso di allentamento del bullone di serraggio 23 à ̈ impedito lo sfilamento, in quanto l'anello tagliato à ̈ alloggiato nella rientranza anulare 21, per cui, in caso di allentamento, al massimo si hanno delle perdite che evidenziano la necessità di procedere al serraggio del bullone. With the arrangement described, it is obtained that even in the event of loosening of the tightening bolt 23 it is prevented from slipping, since the cut ring is housed in the annular recess 21, so that, in the event of loosening, at most there are leaks that highlight the need to tighten the bolt.
Con la disposizione descritta, à ̈ possìbile predisporre un raccordo che à ̈ costituito dal tubo flessibile 5 al quale vengono connessi alle estremità due corpi di raccordo 1, realizzati nel modo in precedenza descritto, che danno la possibilità di eseguire connessioni stabili, senza incorrere nelle difficoltà attualmente riscontrabili con la tecnica nota, dove si ha la necessità di tagliare e sagomare correttamente un tubo rigido. With the arrangement described, it is possible to provide a fitting which is constituted by the flexible pipe 5 to which two fitting bodies 1 are connected at the ends, made in the manner previously described, which give the possibility of making stable connections, without incurring the difficulties currently encountered with the known technique, where it is necessary to cut and shape a rigid tube correctly.
Con la disposizione descritta, si ha inoltre che l'adattatore risulta girevolmente connesso al corpo centrale del raccordo per cui, durante la fase di installazione, non si vengono a creare delle forzature torsionali, dal momento che la parte di raccordo, rigidamente collegata al tubo flessibile, à ̈ scollegata da quella che si innesta nella filettatura prevista sul raccordo fisso, che à ̈ generalmente posizionato a parete. With the arrangement described, the adapter is also rotatably connected to the central body of the fitting so that, during the installation phase, no torsional forces are created, since the fitting part, rigidly connected to the pipe flexible, it is disconnected from the one that engages in the thread provided on the fixed fitting, which is generally positioned on the wall.
Con la soluzione descritta si ha quindi un sensibile abbattimento della tempistica di installazione e dei costi relativi alle operazioni di installazione dei tubi che prevedevano taglio, sagomatura degli spigoli, piegatura. With the described solution there is therefore a significant reduction in the installation time and in the costs relating to the installation operations of the pipes which provided for cutting, shaping of the edges, bending.
Inoltre, la peculiarità di utilizzare un tubo flessibile consente di ridurre drasticamente il numero di staffe da impiegare per irrigidire la tubazione ed inoltre si ha un ottimale assorbimento delle vibrazioni da parte della tubazione flessibile. Furthermore, the peculiarity of using a flexible pipe allows to drastically reduce the number of brackets to be used to stiffen the pipe and furthermore there is an optimal absorption of vibrations by the flexible pipe.
A quanto detto va anche aggiunto che vengono eliminati tutti i possibili infortuni derivanti dalle rischiose operazioni di saldatura, piegatura e taglio dei tubi rigidi. To what has been said it must also be added that all possible injuries deriving from the risky welding, bending and cutting operations of rigid pipes are eliminated.
Il trovato così concepito à ̈ suscettibile di numerose modifiche e varianti tutte rientranti nell'ambito del concetto inventivo. The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept.
Inoltre, tutti i dettagli potranno essere sostituiti da altri elementi tecnicamente equivalenti . Furthermore, all the details can be replaced by other technically equivalent elements.
In pratica, i materiali impiegati, purché compatibili con l'uso specifico, nonché le dimensioni e le forme contingenti potranno essere qualsiasi a seconda delle esigenze. In practice, the materials employed, so long as compatible with the specific use, as well as the contingent shapes and dimensions, may be any according to requirements.
