WOODWARD截止閥GSOV25產(chǎn)品介紹
Woodward GSOV25 HT 燃料截止閥旨在以最快的速度關(guān)閉工業(yè)燃?xì)鉁u輪發(fā)動(dòng)機(jī)中的氣體燃料。閥門關(guān)閉時(shí)，氣流完全停止，從入口到出口沒有泄漏。與標(biāo)準(zhǔn)版本相比，“HT”版本可以承受更高的燃料溫度和更高的背壓。它適用于 -20 至 +177 °C 的氣體溫度。該閥門在反向關(guān)閉時(shí)符合 ANSI Class IV 的關(guān)閉能力，壓差為 3450 kPa。
常閉閥可用于緊急和正常關(guān)閉。特殊的密封設(shè)計(jì)可防止泄漏并延長(zhǎng)使用壽命。不銹鋼結(jié)構(gòu)確保無論在何種腐蝕條件下都能保持高可靠性。
該產(chǎn)品適用于帶有單個(gè)或分支燃料入口歧管的 10 至 50 W 工業(yè)渦輪機(jī)。
描述
GSOV25 HT 燃料截止閥通過快速關(guān)閉氣體燃料的供應(yīng)，提供了一種關(guān)閉燃?xì)鉁u輪機(jī)的方法。施加的壓力用于移動(dòng)閥門中的彈簧活塞。當(dāng)閥門通電時(shí)，氣壓使彈簧活塞保持打開狀態(tài)，使燃料流向渦輪機(jī)。當(dāng)電磁閥的電信號(hào)丟失時(shí)，次級(jí)彈簧活塞將反轉(zhuǎn)以釋放主控制壓力。然后主彈簧迫使主活塞抵住密封件，從而停止流動(dòng)。
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.
