摘要

A safety valve (1), particularly for releasing gas in overpressure, which includes a cylindrical chamber (2) provided with a plurality of lateral holes (3) and with an opening (4) which is provided on the bottom and connects it to the inside of a tank which contains gas; the cylindrical chamber (2) accommodates a flow control means (5) which is biased in abutment against the opening (4) by a spring (6). A fusible device (10) is joined to the top of the cylindrical chamber (2) in order to keep the spring (6) compressed and contrast the thrust of the gas exclusively in normal pressure and temperature conditions.
