<p>The invention concerns a safety valve for a containment chamber (16) comprising a tubular body consisting of a main branch (11) and a secondary branch (12) connected thereto and opening thereinto via a lateral opening. A piston (13) is slidingly mounted inside the main branch (11) in order to free the lateral opening therein, and an upper stop (14) and a lower stop (15) are mounted inside the main branch in order to restrict the movement of the piston (13) upwards and downwards. The lower part of the main branch (11) communicates with a reference pressure region, and an additional safety device (25) is positioned below the tubular body between the lower part of the main branch and the reference pressure region so as to allow the maximum flow rate permitted by the valve in the event of an incident.</p> |
