Steam Turbine Emergency Trip Slide Valve
The steam turbine emergency trip slide valve is a core executive component of the power plant's steam turbine safety protection system. It is widely used in various high-pressure, ultra-high-pressure, and subcritical steam turbine units. As a key element of the emergency trip system, this valve slide valve can quickly and accurately cut off the main steam valve oil supply circuit when the unit experiences an emergency such as overspeeding, excessive vibration, or low lubricating oil pressure. This achieves an emergency shutdown of the steam turbine and effectively prevents equipment damage and safety accidents.
Product Features
- High-Reliability Design: Adopts a modular structural design. The action is sensitive, and the response is fast, ensuring the trip action is completed within milliseconds to guarantee unit safety.
- Precision Manufacturing Process: The core valve slide valve components are processed with high-precision CNC grinding, combined with strict surface treatment (such as chromium plating, nitriding, etc.). This significantly improves wear resistance and corrosion resistance, extending the service life.
- Excellent Sealing Performance: Adopts a multi-layer sealing structure design to effectively prevent oil leakage. This ensures stable system oil pressure and eliminates the risk of false trips or failure to trip.
- Strict Quality Control: Each valve slide valve undergoes pressure testing, action testing, and sealing testing before leaving the factory to ensure stable performance and reliability.
- Action Method: Triggered by a mechanical flyweight/fly-ring or by a solenoid valve linkage.
- Working Temperature: -20°C to +120°C.
- Material: High-quality alloy steel (such as 20CrMo, 38CrMoAl, etc.), with a surface hardening treatment.
- Connection Method: Flange connection or threaded connection.
- Compatible Unit Power: 50MW to 1000MW.
Application Range
Suitable for the emergency trip protection system of steam turbines in thermal power plants, co-generation plants, captive power plants, and industrial drives. It is especially suitable for the main steam valve and regulating steam valve linkage trip control that requires a high safety level.
