    • A two-step, self-regulating valve (16) controls gas flow from a gas cylinder (12) in a high pressure system. The valve (16) includes a valve body (24), a piston (26), a plug (28), a valve actuator (34), and a piston actuator (32). The piston (26) is movable within the valve body (24) along an axis between a first and a second position. The plug (28) is movable within the valve body (24) along the axis between a valve closed position, a partially open position, and a fully open position. The valve actuator (34) allows the plug (28) to move from the valve closed position to the partially open position. The piston actuator (32) causes the piston (26) to move from the first position to the second position when a gas pressure in the gas cylinder (12) is less than a setpoint. When the piston (26) moves to the second position, the piston (26) allows the plug (28) to move from the partially open position to the fully open position.
    • 两级自调节阀(16)控制来自高压系统中的气瓶(12)的气体流量。 阀(16)包括阀体(24),活塞(26),塞子(28),阀致动器(34)和活塞致动器(32)。 活塞(26)可以在阀体(24)内沿第一和第二位置之间的轴线移动。 塞子(28)可以在阀体(24)内沿着轴线在阀关闭位置,部分打开位置和完全打开位置之间移动。 阀致动器(34)允许塞子(28)从阀关闭位置移动到部分打开位置。 当气瓶(12)中的气体压力小于设定值时,活塞致动器(32)使活塞(26)从第一位置移动到第二位置。 当活塞(26)移动到第二位置时,活塞(26)允许塞子(28)从部分打开位置移动到完全打开位置。
