柴油发电机停机电磁阀是如何工作的？ How does the diesel generator shutdown solenoid valve work?

Diesel generator shutdown solenoid valve, also known as shutdown electromagnet, fuel cut-off solenoid valve, shutdown switch, etc., is an important component of diesel generator set and plays a crucial role in the shutdown process of the generator set. The shutdown solenoid valve is a key component of the generator set shutdown control system, responsible for quickly cutting off the fuel supply upon receiving a shutdown signal, enabling the generator set to shut down safely and quickly.

The structural design of the shutdown solenoid valve is unique, usually consisting of components such as an electromagnet, valve body, and valve core. When receiving a shutdown signal, the electromagnetic iron is energized to generate magnetic force, attracting the valve core to move, thereby cutting off the fuel supply. The response speed of the shutdown solenoid valve is crucial in this process, as it directly affects the shutdown speed and safety of the generator set. There are also shutdown solenoid valves that are electromagnetic mechanical in nature. They do not directly control the fuel, but instead cut off the current and use other components to move and intermittently control the throttle actuator switch, thereby disconnecting the fuel shutdown.

In order to ensure that the generator set can be quickly shut down in emergency situations, the shutdown solenoid valve needs to have high reliability and stability. During the design and manufacturing process, the shutdown solenoid valve needs to undergo strict quality control and durability testing to ensure that it can function properly in various harsh environments.
