The solenoid valve J-220VDC-DN6-D-20B/2A, as an important component of the steam turbine control system, plays a crucial role in regulating the flow direction of EH oil and ensuring the safe operation of the system. It can be integrated with control systems to achieve automatic control of steam turbines. By receiving signals from the control system, the valve automatically opens or closes to achieve the preset power output and operating state. During the operation of the steam turbine, abnormal situations may occur, such as overspeed, overload, etc. The electromagnetic directional valve can quickly cut off the oil supply in these situations, prevent accidents from expanding, and ensure system safety.

The fault monitoring methods for solenoid valve J-220VDC-DN6-D-20B/2A include sensor monitoring, control system analysis, fault diagnosis system, visual and sound inspection, etc. Sensors can monitor key parameters such as oil flow rate, pressure, and temperature in real-time. After receiving sensor signals, the control system will analyze and judge. If it detects that the electromagnetic directional valve cannot work or respond properly, the control system will automatically trigger an alarm or make adjustments. Advanced steam turbine systems may be equipped with fault diagnosis systems that can monitor the working status of electromagnetic directional valves in real-time and diagnose potential faults through data analysis. Operators can also preliminarily determine whether there is a malfunction by observing the appearance of the electromagnetic directional valve and listening to its working sound.

In case of emergency, if the electromagnetic directional valve fails, the operator can manually close the relevant emergency stop device, cut off the oil supply, and stop the operation of the turbine. When the automatic control system fails, the operator can manually operate the valve to control the direction and flow of oil. If the main electromagnetic directional valve malfunctions, the operator can manually switch to the backup electromagnetic directional valve to ensure the stable operation of the turbine. Manual intervention also includes inspection and maintenance of the electromagnetic directional valve. Operators can regularly open the valve, inspect internal components for damage or wear, and perform necessary cleaning and replacement. During manual intervention, operators may need to adjust the operating parameters of the system, such as oil pressure and temperature, to adapt to the effects of valve failures.

By means of real-time monitoring, manual operation, and fault handling, the safe and reliable operation of the electromagnetic directional valve can be ensured, energy utilization efficiency can be improved, and the risk of faults can be reduced. Operators should be proficient in relevant skills to ensure that they can respond quickly and effectively in case of malfunctions.
