WOODWARD截止阀GSOV25产品介绍
Woodward GSOV25 HT 燃料截止阀旨在以最快的速度关闭工业燃气涡轮发动机中的气体燃料。阀门关闭时，气流完全停止，从入口到出口没有泄漏。与标准版本相比，“HT”版本可以承受更高的燃料温度和更高的背压。它适用于 -20 至 +177 °C 的气体温度。该阀门在反向关闭时符合 ANSI Class IV 的关闭能力，压差为 3450 kPa。
常闭阀可用于紧急和正常关闭。特殊的密封设计可防止泄漏并延长使用寿命。不锈钢结构确保无论在何种腐蚀条件下都能保持高可靠性。
该产品适用于带有单个或分支燃料入口歧管的 10 至 50 W 工业涡轮机。
描述
GSOV25 HT 燃料截止阀通过快速关闭气体燃料的供应，提供了一种关闭燃气涡轮机的方法。施加的压力用于移动阀门中的弹簧活塞。当阀门通电时，气压使弹簧活塞保持打开状态，使燃料流向涡轮机。当电磁阀的电信号丢失时，次级弹簧活塞将反转以释放主控制压力。然后主弹簧迫使主活塞抵住密封件，从而停止流动。
The Woodward GSOV25 HT Fuel Shutoff Valve is designed to provide the fastest shutoff possible for gaseous fuel in industrial gas turbine engines. Gas flow is completely stopped when the valve closes, and there is no leakage from inlet to outlet. The “HT” version can withstand higher fuel temperatures and higher back pressure than the standard version. It is suitable for gas temperatures from -20 to +177 °C. The valve meets the shutoff capability of ANSI Class IV in the reverse direction with a pressure differential of 3450 kPa.
The normally-closed valve can be used for both emergency and normal shutoff. Special seal design prevents leakage and prolongs service life. Stainless steel construction ensures high reliability regardless of corrosive conditions.
The product is suitable for use on industrial turbines from 10 to 50 W with a single or branched fuel inlet manifold.
Description
The GSOV25 HT Fuel Shutoff Valve provides a means of shutting down a gas turbine by quickly shutting off the supply of gaseous fuel. The applied pressure is used to move a spring-loaded piston in the valve. When the valve is energized, the gas pressure holds the spring-loaded piston open, allowing fuel to flow to the turbine. When the electrical signal to the solenoid is lost, the secondary spring-loaded piston reverses to relieve the primary control pressure. The main spring then forces the primary piston against the seal, stopping the flow.
