The trip solenoid valve 165.31.56.04.01 plays a crucial role in the emergency shutdown protection system of the steam turbine. It can quickly act upon detecting abnormal equipment operation or receiving emergency shutdown signals to cut off the heat and power sources of the steam turbine, preventing further equipment damage or accidents. AST systems typically include multiple components, such as high-temperature and high-pressure shut-off valves, solenoid valves, sensors, control logic, etc.

Among these components, the trip solenoid valve 165.31.56.04.01 is responsible for quickly cutting off the heat or power flow of the turbine in emergency situations. When the system detects dangerous signals such as overspeed, abnormal temperature, and abnormal pressure, the AST control logic will quickly send signals to the solenoid valve, activate the solenoid coil to generate magnetic force, and push the valve mechanism to move, thereby achieving the goal of quickly cutting off the fluid medium.

The AST automatic trip solenoid valve 165.31.56.04.01 needs to have the following characteristics in its design:

• 1. Quick response: In emergency situations, the solenoid valve needs to be able to act within milliseconds to quickly cut off the fluid.
• 2. High temperature tolerance: The working environment temperature of the steam turbine is high, and the solenoid valve needs to be able to withstand high temperatures.
• 3. High pressure withstand: The solenoid valve needs to be able to withstand the high pressure in the turbine system.
• 4. Reliability: In emergency situations, the solenoid valve must be able to work reliably without any errors.
• 5. Material: The material of the solenoid valve needs to be able to resist the corrosion of the turbine medium (such as steam).
• 6. Protective measures: Electromagnetic valves need to have good protective measures to prevent external factors (such as dust, moisture, grease) from affecting the valve.

In the operation and maintenance of steam turbines, the normal operation and regular inspection of the AST trip solenoid valve 165.31.56.04.01 are important links to ensure the safe operation of the equipment. Regular inspection and maintenance of the solenoid valve can ensure its reliable operation in emergency situations, thereby ensuring the safe operation of the steam turbine.
