<p>A fast-flow discharge valve (1) designed to be fitted to the mouth of tanks (2) containing inert gases for fire extinguishing systems is described. The discharge valve (1) comprises: an obturator (62) moveable axially in a lower chamber (52) of the valve body communicating with the inside of the tank (2) to impede/allow the flow of extinguishing fluid toward a radial discharge passage (56); a service valve (8) provided with an obturator (42) able to open/close the communication between said lower chamber (52) and respective service passages (86, 84, 82) destined to be connected respectively to a solenoid valve (110), to a manostat (150) and to a pressure gauge (140); and a recharge valve (46) provided with an obturator (45) able to open/close the communication between said lower chamber (52) and a recharge passage (48) formed in the valve body and designed to be connected to a hose for introduction of the recharging extinguishing fluid. <IMAGE></p> |
