The working principle of automobile brake valve:
Automobile brake valve braking uses the engine rotation resistance generated by driving the engine in the reverse direction from the drive shaft to brake the car.
The braking device of the automobile brake valve is divided into: the electric control air pressure type that uses the electric device to control the compressed air to open and close the exhaust automobile brake valve, and the electric device to control the vacuum device to open and close the exhaust automobile brake valve Two types of electronically controlled vacuum type.
Electronically controlled pneumatic automobile brake valves are divided into: automobile brake valve system is mainly composed of air circuit switch solenoid valve, exhaust brake valve and longitudinal cylinder.
How to use automobile brake valve:
When a car is running, especially when the vehicle is going down a long slope, the vehicle needs to be decelerated. At this time, it is best to use the exhaust brake valve of the car brake valve to reduce the burden of wheel brakes and reduce driver fatigue.
If the exhaust brake device is required to work, turn on the exhaust brake switch, and the electrical system of the exhaust brake device is connected to the battery, thereby turning on the solenoid valve for controlling the supply of compressed air to the control cylinder and the exhaust of compressed air. The air cylinder compressed air enters the control cylinder. After the control cylinder works, the exhaust brake is in the closed state, and the engine brake is generated. The exhaust brake indicator light is on.
