Introduction：
JF3 emergency valve is generally used for locomotive brakes. It is connected to the train pipe and the 1.5L emergency room. When the train pipe drops at the emergency braking rate, the emergency valve can be activated to quickly open the train pipe to exhaust the atmosphere, accelerate the exhaust of the train pipe, and turn on the JF3 emergency valve at the same time. The micro switch changes the on-off state to connect the relevant emergency protection circuit. Once the JF3 emergency valve is activated, it must be held for a certain period of time before resetting.
