AST solenoid valve JZ-PK-001 plays a vital role in turbine control. During normal operation, the solenoid valve is energized and closed to ensure that the AST oil leakage channel on the emergency trip main pipe is blocked, thereby maintaining the emergency trip oil pressure (AST). When the solenoid valve is powered off and opened, the emergency trip main pipe leaks oil, causing the AST oil pressure to drop, which in turn triggers the closure of all steam valves and stops the turbine. This design ensures that in an emergency, the system can respond quickly and take protective measures to avoid equipment damage and safety accidents.

Technical parameters

• Working voltage: usually 220V AC or 110V DC, the specific voltage needs to be determined according to the actual application and system requirements.

• Response time: The response time is extremely short, ensuring that it can act quickly in an emergency and cut off the steam inlet of the turbine in time.

• Pressure range: Able to withstand higher working pressures, the specific pressure range needs to be determined according to actual working conditions and system design.

• Working medium: Suitable for oil medium in steam turbine control system.

• Action mode: Adopt the reverse logic design of power-on closing and power-off opening to ensure that the solenoid valve can operate reliably in emergency situations.

• Sealing performance: It has excellent sealing performance to prevent oil leakage and ensure the normal operation and safety of the system.

Application

AST solenoid valve JZ-PK-001 is mainly used in the control system of steam turbine units in power plants as a key component of emergency shutdown. It can quickly cut off the steam inlet of the steam turbine when the steam turbine fails or other emergencies occur, prevent the accident from expanding, and protect the safety of equipment and personnel. In addition, the solenoid valve can also be used in other industrial control systems that need to quickly cut off fluid media, such as petrochemical, metallurgy, machinery manufacturing and other industries.

Installation and maintenance

• Installation points: When installing the AST solenoid valve JZ-PK-001, it is necessary to ensure that the flow direction of the solenoid valve is consistent with the flow direction marked in the pipeline to avoid reverse flow caused by installation errors. At the same time, it is necessary to ensure the sealing of the connection between the solenoid valve and the pipeline to prevent medium leakage.

• Maintenance suggestions: Regularly check the sealing performance and operational flexibility of the solenoid valve to promptly identify and handle potential problems. During maintenance, pay attention to the protection of key components such as the solenoid valve to avoid damage caused by improper operation.

AST solenoid valve JZ-PK-001 has become an indispensable key component in the turbine control system with its high reliability and fast response. It can quickly cut off the steam inlet of the turbine in an emergency to protect the safety of equipment and personnel.
