"RACCORDO DI USCITA PARTICOLARMENTE PER POMPE A VIBRAZIONE" "OUTLET FITTING PARTICULARLY FOR VIBRATION PUMPS"
DESCRIZIONE DESCRIPTION
Il presente trovato si riferisce ad un raccordo di uscita particolarmente per pompe a vibrazione . The present invention relates to an outlet fitting particularly for vibration pumps.
Come è noto, nelle pompe a vibrazione che sono generalmente utilizzate su caldaie di alimentazione di elettrodomestici quali, ad esempio, le macchine dedicate alla preparazione delle bevande ottenute per infusione, quali caffè, tè o simili, viene normalmente previsto un raccordo di uscita per la connessione ai diversi componenti. As is known, in vibration pumps which are generally used on supply boilers for household appliances such as, for example, machines dedicated to the preparation of beverages obtained by infusion, such as coffee, tea or the like, an outlet fitting is normally provided for the connection to the different components.
I raccordi vengono attualmente realizzati per stampaggio utilizzando diverse materie plastiche, quali, ad esempio, nailon caricato con fibra di vetro o, eventualmente, vengono realizzati in materiale metallico, partendo da barre di ottone che vengono tornite. The fittings are currently made by molding using various plastic materials, such as, for example, nylon loaded with glass fiber or, possibly, they are made of metal, starting from brass bars that are turned.
I raccordi in materia plastica presentano indubbi vantaggi economici, ma comportano seri limiti sulle tolleranze dimensionali dei componenti con essa realizzati, determinando in molti casi una riduzione delle prestazioni attese dei dispositivi e obbligando a scegliere, come elementi di giunzione, raccordi in plastica della medesima tipologia o comunque dotati di filetti di innesto cilindrici . Plastic fittings have undoubted economic advantages, but involve serious limits on the dimensional tolerances of the components made with them, causing in many cases a reduction in the expected performance of the devices and forcing to choose, as joining elements, plastic fittings of the same type or in any case equipped with cylindrical coupling threads.
Il raccordo in materiale metallico consente di curare in modo ottimale la precisione costruttiva, incidendo però sensibilmente sul costo del prodotto, sia per la materia prima utilizzata, sia per la necessità di operare trattamenti superficiali che consentano l'impiego alimentare e la riduzione di fenomeni di incollaggio delle guarnizioni su sedi di tenuta dinamiche. The connection in metal material allows to take care of the construction precision in an optimal way, however significantly affecting the cost of the product, both for the raw material used, and for the need to operate surface treatments that allow the use of food and the reduction of phenomena of bonding of gaskets on dynamic sealing seats.
Il compito che si propone il trovato è appunto quello di risolvere i problemi sopra esposti realizzando un raccordo di uscita particolarmente per pompe a vibrazione che consenta di coniugare in sé gli aspetti ottimali delle due soluzioni sopra proposte, senza averne gli aspetti negativi connessi . The aim of the invention is precisely that of solving the aforementioned problems by providing an outlet fitting particularly for vibration pumps which allows to combine within itself the optimal aspects of the two solutions proposed above, without having the connected negative aspects.
Nell'ambito del compito sopra esposto, uno scopo particolare del trovato, è quello di realizzare un raccordo che consenta l'accoppiamento con qualsiasi tipo di filetto, compresi i filetti conici . Within the scope of the above aim, a particular object of the invention is to provide a fitting which allows coupling with any type of thread, including conical threads.
Un ulteriore del presente trovato è quello di realizzare un raccordo che non necessiti di finiture o trattamenti specifici sulle superfici di tenuta . A further feature of the present invention is to provide a fitting which does not require specific finishes or treatments on the sealing surfaces.
Un ulteriore scopo del presente trovato è quello di realizzare un raccordo di uscita che, per le sue peculiari caratteristiche realizzative, sia in qrado di dare le più ampie qaranzie di affidabilità e sicurezza nell'uso. A further object of the present invention is to provide an outlet fitting which, due to its particular constructive characteristics, is capable of giving the greatest guarantees of reliability and safety in use.
Non ultimo scopo del presente trovato è quello di realizzare un raccordo di uscita particolarmente per pompe a vibrazione che risulti facilmente ottenibile a partire da elementi e materiali di comune reperibilità in commercio, e che, inoltre, sia competitivo da un punto di vista puramente economico . Not least object of the present invention is to provide an outlet fitting particularly for vibration pumps which can be easily obtained starting from commonly available elements and materials on the market, and which, moreover, is competitive from a purely economic point of view.
Il compito sopra esposto, nonché qli scopi accennati ed altri che meqlio appariranno in seguito, vengono raggiunti da un raccordo di uscita particolarmente per pompe a vibrazione, secondo il trovato, caratterizzato dal fatto di comprendere un corpo di attacco ad una pompa a vibrazione, realizzato in materia plastica, ed una bussola esterna, realizzata in materiale metallico, detta bussola esterna essendo connessa a tenuta a detto corpo di attacco, detta bussola esterna definendo una sede filettata in materiale metallico per la connessione dei componenti a valle della pompa a vibrazione . The aforementioned aim, as well as the aforementioned objects and others which will appear more clearly in the following, are achieved by an outlet fitting particularly for vibration pumps, according to the invention, characterized in that it comprises a body for attachment to a vibration pump, made made of plastic material, and an external bush, made of metal material, said external bush being connected tightly to said attachment body, said external bush defining a threaded seat in metal material for the connection of the components downstream of the vibration pump.
Ulteriori caratteristiche e vantaggi risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita, ma non esclusiva, di un raccordo di uscita particolarmente per pompe a vibrazione, illustrato 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 an outlet fitting particularly for vibration pumps, illustrated by way of non-limiting example with the aid of the accompanying drawings in which:
la figura 1 rappresenta il raccordo di uscita, secondo il trovato, in sezione assiale; Figure 1 is an axial section view of the outlet fitting according to the invention;
la figura 2 evidenzia la bussola esterna; le figure 3 e 4 rappresentano in sezione assiale due varianti realizzative del raccordo di uscita; figure 2 shows the external bush; Figures 3 and 4 show in axial section two embodiments of the outlet fitting;
la figura 5 rappresenta il raccordo di uscita applicato ad una pompa a vibrazione. figure 5 represents the outlet fitting applied to a vibration pump.
Con riferimento alle citate figure, il raccordo di uscita particolarmente per pompe a vibrazione, che viene indicato nella sua modalità con il numero di riferimento 1, comprende un corpo di attacco 2, che è realizzato in materia plastica preferibilmente, ma non necessariamente, costituita da nailon caricato con fibra di vetro che definisce ad una sua estremità mezzi di attacco ad una pompa a vibrazione 3; tali mezzi sono, ad esempio, costituiti da una flangiatura di estremità 4. With reference to the aforementioned figures, the outlet fitting particularly for vibration pumps, which is indicated in its modality with the reference number 1, comprises an attachment body 2, which is made of plastic material preferably, but not necessarily, consisting of nylon reinforced with glass fiber which defines at one end means for attachment to a vibration pump 3; such means are, for example, constituted by an end flanging 4.
Al corpo di attacco 2 viene connessa una bussola esterna 10 che è realizzata in materiale metallico, ad esempio ottone, lavorato per tornitura . An external bush 10 is connected to the attachment body 2 which is made of a metal material, for example brass, worked by turning.
La bussola 10 viene connessa a tenuta al corpo di attacco 2 tramite mezzi di connessione costituiti da un codolo 11 che è definito sulla bussola e presenta alla estremità libera un collare di attacco 12 affiancato ad una fascia a profilo zigrinato 13 a fianco del quale risulta prevista una gola 14 per l'inserimento di una guarnizione di tenuta 15. The bush 10 is connected tightly to the attachment body 2 by means of connection means consisting of a tang 11 which is defined on the bush and has at its free end an attachment collar 12 flanked by a knurled profile band 13 alongside which it is provided a groove 14 for the insertion of a sealing gasket 15.
La bussola esterna 10 definisce una sede filettata 16 in materiale metallico per la connessione dei componenti a valle della pompa a vibrazione 3. The external bush 10 defines a threaded seat 16 in metallic material for the connection of the components downstream of the vibration pump 3.
La bussola, come illustrato nelle figure 1 e 2, viene forzata all'interno del corpo di attacco in materia plastica tramite un procedimento termico o ad ultrasuoni e grazie alla zigrinatura elicoidale della fascia 13 risulta in grado di resistere sia a coppie meccaniche che a sollecitazione di trazione. The bush, as illustrated in Figures 1 and 2, is forced inside the plastic material attachment body by means of a thermal or ultrasonic process and thanks to the helical knurling of the band 13 it is able to withstand both mechanical torques and stress of traction.
Il riscaldamento indotto sulla bussola esterna 10 consente il suo inserimento all'interno del corpo di attacco 2 in materia plastica e al tempo stesso permette alla plastica rammollita di aggrapparsi efficacemente al profilo zigrinato 13. The heating induced on the external bush 10 allows its insertion inside the attachment body 2 made of plastic material and at the same time allows the softened plastic to cling effectively to the knurled profile 13.
Per garantire una ottimale tenuta nella gola 14 viene previsto un OR 15 che completa l'azione di tenuta . To ensure an optimal seal in the groove 14 an OR 15 is provided which completes the sealing action.
Secondo quanto illustrato nelle soluzioni illustrate nelle figure 3 e 4 vengono previste varianti realizzative in cui i mezzi di connessione presentano sulla bussola esterna una filettatura per l'accoppiamento al corpo di attacco. According to what is illustrated in the solutions illustrated in Figures 3 and 4, embodiment variants are provided in which the connection means have a thread on the external bush for coupling to the attachment body.
A questo scopo, come illustrato in figura 3 i mezzi di connessione del corpo di attacco indicato con 2', presentano una filettatura di accoppiamento 20 che è posizionata su una sporgenza assiale 21 alla cui base è prevista una rientranza anulare 22 per l'inserimento di una guarnizione di tenuta di accoppiamento 23. Corrispondentemente la bussola esterna, indicata con 10', definisce una filettatura femmina 25 che consente di sovrapporsi alla filettatura di accoppiamento 20 per realizzare l'accoppiamento ed eseguire la tenuta grazie alla guarnizione di accoppiamento 23. For this purpose, as illustrated in Figure 3, the connecting means of the attachment body indicated with 2 ', have a coupling thread 20 which is positioned on an axial projection 21 at the base of which an annular recess 22 is provided for the insertion of a coupling seal gasket 23. Correspondingly, the external bush, indicated with 10 ', defines a female thread 25 which allows to overlap the coupling thread 20 to make the coupling and perform the seal thanks to the coupling gasket 23.
Secondo quanto illustrato in figura 4, i mezzi di connessione del corpo di attacco indicato con 2", presentano una protuberanza assiale 30 che, alla sua estremità libera, definisce una sede frontale 31 per l'alloggiamento di una guarnizione anulare di accoppiamento 32. According to what is illustrated in Figure 4, the connecting means of the attachment body indicated with 2 ", have an axial protuberance 30 which, at its free end, defines a front seat 31 for housing an annular coupling gasket 32.
La protuberanza 30 presenta una zona filettata esterna 33 che si accoppia con una zona filettata interna 34 realizzata dalla bussola in materiale metallico, indicata con 10". The protuberance 30 has an external threaded area 33 which is coupled with an internal threaded area 34 made by the bush made of metal material, indicated with 10 ".
Anche in questo caso si realizza un accoppiamento a tenuta tra due componenti di diverso materiale e la tenuta viene direttamente effettuata dalla guarnizione anulare 32 che è posta all'estremità libera di accoppiamento. Also in this case a sealed coupling is made between two components of different material and the seal is directly carried out by the annular gasket 32 which is placed at the free coupling end.
A quanto detto va anche aggiunto che il corpo di attacco definisce al suo interno una sede conica 40 per l'impegno con eventuali guarnizioni di tenuta, potendo così realizzare le tenute dinamiche su una zona in materia plastica che elimina le difficoltà tipiche delle tenute dinamiche effettuate su materiali metallici. To what has been said it should also be added that the attachment body defines inside it a conical seat 40 for engagement with any sealing gaskets, thus being able to make dynamic seals on a plastic area that eliminates the typical difficulties of dynamic seals performed. on metallic materials.
Da quanto sopra illustrato si vede quindi come il trovato raggiunga gli scopi proposti ed in particolare si sottolinea come vengono superati i problemi di adesione della guarnizione con le superfici metalliche, poiché tutte le aree critiche sono realizzate in materia plastica. From what has been illustrated above, it can therefore be seen how the invention achieves the intended aim and objects and in particular it is emphasized that the problems of adhesion of the gasket with the metal surfaces are overcome, since all the critical areas are made of plastic material.
Inoltre il corpo di attacco realizzato in materia plastica, rappresenta una dimensione ridotta rispetto alle soluzioni analoghe in corpo unico in materia plastica, per cui si può ottenere una migliore precisione dimensionale da stampaggio. Furthermore, the attachment body made of plastic material represents a reduced size with respect to similar solutions in a single plastic body, so that a better dimensional precision by molding can be obtained.
A quanto detto va anche aggiunto che il componente ottenuto con una parte in materia plastica ed una parte in materiale metallico presenta un costo considerevolmente inferiore rispetto al raccordo realizzato interamente in materiale metallico, senza compromettere significativamente le prestazioni che sono influenzate dalla precisione dimensionale delle aree di tenuta. To what has been said it should also be added that the component obtained with a part in plastic material and a part in metal material has a considerably lower cost compared to the fitting made entirely of metal material, without significantly compromising the performances which are influenced by the dimensional accuracy of the areas of estate.
Inoltre l'aver realizzato una sede filettata in materiale metallico per la connessione dei componenti a valle della pompa a vibrazione consente il montaggio di giunzioni coniche e risulta dimensionalmente più preciso. Furthermore, having made a threaded seat in metal material for the connection of the components downstream of the vibration pump allows the assembly of conical joints and is dimensionally more precise.
Il trovato così concepito è suscettibile di numerose modifiche e varianti tutte ri ntranti nell'ambito del concetto inventivo The invention thus conceived is susceptible of numerous modifications and variations, all of which fall within the scope of the inventive concept
Inoltre tutti i dettagli potranno essere qualsiasi a seconda delle esigenze Furthermore, all the details can be any according to the needs
