Abstract

Le due parti di corpo o contenitore (1, 2) di una valvola a membrana vengono serrate insieme mediante connessione a vite (5), ove fra le parti di contenitore (1, 2) è disposta una membrana elastomerica (3). Fra la parte inferiore (1) del contenitore ed un dado (9) avvitato su ciascun perno filettato (6) è disposta ogni volta una molla di compressione a spirale (10), che presenta una sezione trasversale (12) rettangolare delle spire.
