WOODWARD燃气阀GSOV50产品描述
GSOV50 燃料隔离阀通过快速切断气体燃料的流动，实现燃气轮机的停机。供气压力用于推动阀门内的弹簧活塞。阀门通电后，气压驱动弹簧活塞打开，使燃料进入涡轮机。当电磁阀的电流信号中断时，弹簧式二级活塞会改变状态，释放主控制压力。然后，主弹簧将主活塞压向密封圈，从而停止所有燃料流动。
The GSOV50 fuel isolation valve provides shutdown on a gas turbine by rapidly halting the flow of gaseous fuel. The supply pressure is used to move a spring-loaded piston in the valve. When the valve is energized, gas pressure drives the spring-loaded piston open, admitting fuel to the turbine. When the current signal to the electrical solenoid is interrupted, the spring loaded second-stage piston changes states to vent off primary control pressure. The main spring then forces the primary piston to the seal, stopping all flow.
