TEMPO DI ESSICAZIONE / DRYING TIME
Osservando i dati della tabella si potrebbe concludere
che i tempi siano elevati,specialmente alle
temperature basse, non è così in quanto la quantità
d’aria che si accumola giornalmente in un radiatore
è assolutamente trascurabile. Perciò alla valvolina
igroscopica il tempo di essicamento consente
tranquillamente di tenere il passo al ciclo formazione
aria/eliminazione aria. La valvola ha una durata media
di 5 anni, ciò dipende da quanto si siano degradati i
dischetti nel tempo in presenza di acque non ﬁltrate o
particolarmente calcaree.
Looking at the dare on the table, anyone could be
conclude that the time is high, especially at low
temperature basse. It is not, because the amount of
air that daily accumulation in a radiator is negligible.
Therefore, the valve hygroscopic drying time
allows easily to keep up the training cycle air / air
elimination. The valve has an average duration of 5
years, depending on how they are degraded over time
the discs. in the presence of water is not ﬁltered or
particularly limestone.
L’acqua che entra nel radiatore bagna
i dischetti facendoli espandere.
Water entering the valve from the
radiator expands the hygroscopic
washers.
I dischetti espandendosi chiudono la
valvola premendo verso il basso la
rondella bianca.
The expanded washers close
the valve by pushing the plastic
containing a vitol seal against the
inlet port.
La sostituzione della valvola deve
avvenire quando i dischetti perdendo
la proprietà igroscopica andranno a
chiudere in modo deﬁnitivo la valvola.
At the end of valve life the top safety
washers expand and close the valve
permanently.
La tabella si riferisce ad un ciclo di pressione di 1 bar. / The table refers to a cycle of 1 bar pressure.
