    摘要: A pressure-reducing valve for an automatic fire-extinguishing system comprises a valve housing (7) having a longitudinal axis (8), with an inlet opening (9) for connecting the pressure-reducing valve (5; 5a; 5b; 5c; 5d; 5e; 5f; 5g) to a pressure container (2) in which an extinguishing medium is stored under high pressure (p
    H ), with an outlet opening (10) for connecting the pressure-reducing valve (5; 5a; 5b; 5c; 5d; 5e; 5f; 5g) to an extinguishing-medium-dispensing device (6), and with a flow channel (14) which is arranged between the inlet opening (9) and the outlet opening (10), and comprises a pressure-regulating piston (24; 24a; 24b; 24c; 24d; 24f; 24g) which is displaceable in the valve housing (7) along the longitudinal axis (8) between an open position and a closed position, a first sealing element (19; 19c; 19d; 19, 19e; 19f, 51), which is arranged along the flow channel (14), for bearing in a sealing manner against the pressure-regulating piston (24; 24a; 24b; 24c; 24d; 24f; 24g) in the closed position, a force accumulator element (33) for exerting an opening force (F
    1 ) on the pressure-regulating piston (24; 24a; 24b; 24c; 24d; 24f; 24g) for shifting the latter into the open position, wherein, in the closed position of the pressure-regulating piston (24; 24a; 24b; 24c; 24d; 24f; 24g), the first sealing element (19; 19c; 19d; 19, 19e; 19f, 51) separates a high-pressure chamber (36), which faces the inlet opening (9), of the flow channel (14) in a fluid-tight manner from a low-pressure chamber (37), which faces the outlet opening (10), of the flow channel (14), wherein the extinguishing medium is stored under high pressure (p
    H ) in the high-pressure chamber (36) and under low pressure (p
    N ) in the low-pressure chamber (37), and wherein the extinguishing medium causes a closing force (F
    2 ), which opposes
    the opening force (F
    1 ) on the pressure-regulating piston (24; 24a; 24b; 24c; 24d; 24f; 24g) for shifting the latter into the closed position.

    摘要: The invention relates to a valve for a pressure vessel of an automatic fire extinguishing system, comprising a valve housing (14) having a valve outlet opening (30) for connecting an extinguishing line (6), a valve inlet opening (16) for connecting the valve (3) to the pressure vessel (2), a valve seat (25) disposed between the valve outlet opening (30) and the valve inlet opening (16), a low pressure chamber (24) for connecting an initiating device (5), and a high pressure chamber (33) that can be connected to the low pressure chamber (24), wherein a closing piston (26) comprising a valve seat seal (27) is disposed in the valve housing (14) and can be displaced between a closing piston closed position and a closing piston open position, a pressure regulating unit (21) having a pressurized connection to the valve inlet opening (16) and the low pressure chamber (24) for regulating a low pressure (p
    N ) in the low pressure chamber (24) relative to a tank pressure (p
    B ) of the pressure vessel (2), and a control piston (52) that can be displaced between a control piston closed position and a control piston open position, wherein the closing piston (26) is disposed on the valve seat (25) with the valve seat seal (27) in a fluid tight manner in the closing piston closed position, such that the valve outlet opening (30) is sealed off relative to the valve inlet opening (16), wherein the closing piston (26) is disposed at a distance from the valve seat (25) in the closing piston open position, such that the valve outlet opening (30) and the valve inlet opening (16) have a pressurized connection, wherein the control piston (52) seals off a pressure channel (42, 43) between the high pressure chamber (33) and the low pressure chamber (24) in a fluid tight manner in the control piston closed position, and wherein the control piston (52) exposes the pressure channel (42, 43) in the control piston open position, so that the high pressure chamber (33) and the low pressure chamber (24) have a pressurized connection.
