2017年11月16日 · I just want to share and confirm an information that i have about using two gas valves (SRV and GCV) in the frame 5 GTs. The first valve SRV (speed regulating valve) regulates the infravalve pressure (between srv and gcv). This pressure depends on the hp speed.

2006年6月8日 · One of the most common "failures" of GCV and SRV components is the valve stems wear excessively in one area if run for long periods of time at constant load with a fairly constant gas fuel supply pressure.

2024年6月18日 · The SRV is used to control the intervalve gas pressure—the pressure of the gas fuel between the outlet of the SRV and the inlet of the GCV. This is also called the P2 pressure, and its signal name is usually FPRG.

The double-container valve is an innovative design which consists of two parts, SRV (Stop Ratio Valve) followed by GCV (Gas Control Valve), in a compact unit. SRV maintains a significantly low pressure upstream of the GCV during gas turbine firing to establish flame and control fuel flow during acceleration.

Figure 1 represents a schematic diagram of a double-container valve; it consists of a primary stop/ratio valve (SRV), the left part, followed by a secondary gas control valve (GCV), both in a...

2018年10月1日 · A first-order linear function was also used for the stop/ratio valve (SRV), and the coefficients of this function were derived from the data provided in the monitoring system. Since the fuel valve of the studied turbine has SRV and GCV valves, the ISA standard relationships were used for its modeling.

Learn the stroke checking procedure for GCV, SRV, IGV, and LFBV using the Mark V gas turbine control system. Make sure that cool down, crank, or off mode is selected (L3ADJ should be 1). …

2019年7月1日 · The double-container valve is an innovative design which consists of two parts, SRV (Stop Ratio Valve) followed by GCV (Gas Control Valve), in a compact unit. SRV...

2017年3月24日 · Two valves, usually within the same valve body, control two variables: pressure and flow. Gas pressure “upstream of” the gas control valve (abbreviated GCV) is controlled by the Gas Stop Speed/Ratio Valve (abbreviated SRV). The SRV receives two signals for the purpose of control: turbine speed (NHP) and the inter-valve pressure, P2.

srv应该是控制阀后压力控制阀吧，srv开度是高压轴转速的函数， gcv是根据负荷来控制燃气流量，虽然对燃料进行压力和温度的修正， 二者之间应该没关系
