The role of trailer valveIts function principle
The compressed air in the air pipe of the trailer brake valve to the separation switch is rapidly discharged. At this time, the trailer for gas distribution valve and the trailer cylinder of compressed air into the trailer brake chamber, and the main vehicle to produce the braking effect. When the brake pedal is relaxed, the compressed air from the main vehicle brake valve is discharged into the atmosphere, and the trailer is braked at the same time.
The trailer brake valve has three vents: one through cylinder, one through main vehicle, a brake valve, and one through disconnecting switch. When the car is braking, the compressed air from the main vehicle brake valve enters the trailer brake valve, and closes the air inlet passage of the air storage tank (the wet air storage tank) to cut off the gas source,
Trailer valve, also known as trailer brake valve, the role is to control the driver to cut off the trailer gas supply pipeline, while the gas supply pipe and the atmosphere through the brake.
