<p>A safety device for a gas or steam pressure vessel, including at least one downstream valve (6) connected to the pressure vessel via a tubing (3) with a burst disc (4) dividing the tubing (3) into an upstream section (A) and a downstream section (B). The device is characterised in that the downstream section (B) comprises a protective assembly (15) for minimising the maximum pressure of a shock wave generated when the burst disc (4) is broken and striking the flap of the or each valve (6).</p> |
