Description
VALVOLA DI INTERCETTAZIONE A SFERA FLOTTANTE. FLOATING BALL SHUT-OFF VALVE.
La presente invenzione ? relativa ad una valvola di intercettazione a sfera flottante. In particolare, l?invenzione in oggetto viene vantaggiosamente impiegata nel settore degli impianti e apparecchiature antincendio, preferibilmente del tipo a spegnimento fiamme utilizzando fluidi di flusso come gas inerti o equivalenti, cui la descrizione che segue far? esplicito riferimento senza per questo perdere in generalit?. The present invention ? relating to a floating ball shut-off valve. In particular, the invention in question is advantageously used in the field of fire-fighting systems and equipment, preferably of the flame-extinguishing type using flow fluids such as inert gases or equivalent, to which the following description will refer explicit reference without losing in generality?.
Lo scopo della presente invenzione ? quello di realizzare una valvola di intercettazione a sfera flottante in grado di resistere a pressioni di lavoro molto elevate, con anche notevole resistenza in caso di esplosioni. The purpose of the present invention ? that of making a floating ball shut-off valve capable of withstanding very high working pressures, with also considerable resistance in the event of explosions.
Un altro scopo della presente invenzione ? quello di realizzare una valvola di intercettazione a sfera flottante che risulti di rapida manutenzione ed anche economicamente competitiva dal punto di vista dei costi di fabbricazione. Another object of the present invention ? that of realizing a floating ball shut-off valve which is quick to maintain and also economically competitive from the point of view of manufacturing costs.
Le caratteristiche strutturali e funzionali della presente invenzione e i suoi vantaggi risulteranno ancora pi? chiari ed evidenti dalle rivendicazioni sottostanti, ed in particolare da un esame della descrizione che segue, riferita alle figure allegate, che mostrano alcune preferite ma non limitative forme di realizzazione di una valvola di intercettazione in oggetto, in cui: The structural and functional characteristics of the present invention and its advantages will be even more clear and evident from the underlying claims, and in particular from an examination of the following description, with reference to the attached figures, which show some preferred but non-limiting embodiments of a shut-off valve in question, in which:
- la figura 1 mostra in una vista schematica in sezione ed in scala ingrandita di una preferita forma di attuazione della valvola di intercettazione a sfera flottante in oggetto; e figure 1 is a schematic view in section and on an enlarged scale of a preferred embodiment of the floating ball shut-off valve in question; And
- la figura 2 mostra in una vista schematica in sezione ed in scala ingrandita di un?altra forma realizzativa della valvola di intercettazione della figura 1. - figure 2 shows a schematic view in section and on an enlarged scale of another embodiment of the shut-off valve of figure 1.
Con riferimento alle figure 1 e 2 allegate, con V viene globalmente indicata e rappresentata una valvola di intercettazione e atta ad essere vantaggiosamente e preferibilmente impiegata nel settore degli impianti e apparecchiature antincendio operanti con fluidi di flusso come gas inerti o equivalenti. With reference to the attached figures 1 and 2, V globally indicates and represents a shut-off valve and suitable to be advantageously and preferably used in the sector of fire-fighting systems and equipment operating with flow fluids such as inert gases or equivalent.
La valvola V comprende un corpo 1 cavo ed una ghiera flangiata 2 cava all?interno della quale ? prevista una sede 5 per un otturatore o sfera 3 flottante dotata di foro interno F. The valve V comprises a hollow body 1 and a hollow flanged ring nut 2 inside which ? a seat 5 is provided for a floating obturator or ball 3 equipped with an internal hole F.
Alla sfera 3 ? fissato uno stelo 4 supportante una leva (non illustrata) atta ad essere utilizzata per provocare il movimento della sfera 3 stessa in modo da aprire o chiudere il canale C di circolazione del fluido definito all?interno della valvola V medesima, attraverso l?ausilio di mezzi di interposizione a bussola 6 e premibussola 7. At sphere 3 ? fixed a stem 4 supporting a lever (not shown) able to be used to cause the movement of the ball 3 itself so as to open or close the channel C for the circulation of the fluid defined inside the valve V itself, through the aid of bushing interposition means 6 and bushing holder 7.
La valvola V comprende inoltre dei mezzi a guarnizione 8 di tenuta atti a garantire la ottimale pressione di tenuta, in particolare in caso di elevate pressioni di lavoro. I citati mezzi 6 a bussola e a guarnizione 8 di tenuta sono preferibilmente realizzati in teflon (PTFE) con aggiunta di grafite o materiale equivalente. The valve V further comprises sealing gasket means 8 suitable for guaranteeing the optimum sealing pressure, in particular in the case of high working pressures. The aforementioned bushing means 6 and sealing gasket 8 are preferably made of Teflon (PTFE) with the addition of graphite or equivalent material.
In uso, in posizione aperta la valvola V diventa sostanzialmente una sezione di tubo cavo all?interno del quale ? atto a circolare il fluido in pressione (gas inerte), mentre in posizione chiusa il foro interno alla sfera ? isolato. In use, in the open position the valve V substantially becomes a section of hollow tube inside which ? capable of circulating the fluid under pressure (inert gas), while in the closed position the hole inside the sphere ? isolated.
Preferibilmente ma non limitatamente, le dimensioni ottimali della valvola V vanno da ? di pollice (Figura 2) fino a 3 pollici (Figura 1). Preferably but not limitedly, the optimal dimensions of the valve V range from ? inch (Figure 2) to 3 inches (Figure 1).
