Claim 0:
1. A protection device for a fluid flow line, comprising:
a valve, mobile in the flow line between an open position in which fluid is able to flow in the flow line and a closed position in which fluid is unable to flow in the flow line;
a valve actuator, configured to move the valve to the closed position when a pressure upstream of the valve exceeds a predetermined threshold pressure;
the valve actuator comprising:
a biaser, configured to maintain the valve in the open position;
an actuation mechanism, configured to act against the biaser to move the valve to the closed position, the actuation mechanism delimiting at least a fluid actuated surface able to receive fluid from the flow line;
a fluid sampling passage fluidly connecting the flow line to the fluid actuated surface;
at least one rupture element preventing the passage of fluid from the flow line in the fluid sampling passage downstream of the rupture element when the pressure upstream of the rupture element is lower than the predetermined threshold pressure, the rupture element being configured to break at the predetermined threshold pressure to let fluid from the flow line contact the fluid actuated surface; and;
a removable cartridge containing the at least one rupture element, the removable cartridge being at least partially inserted in the fluid sampling passage.
