The safety valve is a device which allows
to establish the minimum pressure of a
system by keeping it as integral in case of
circuit overpressure.
When pressure inside it practises a highter
strenght compared to the spring which
holds it as closed, the spring opens by
giving fire to the excess-pressure.
La valvola di sicurezza è un dispositivo
che permette di determinare la pressione
massima di un impianto e di mantenerlo
integro in caso di sovrapressione nel
circuito. Quando la pressione all’interno di
quest’ultimo esercita una forza superiore
a quella della molla che lo tiene chiuso,
questa si apre dando libero sfogo alla
pressione in eccesso.
