What is the function of the trailer brake valve?
The trailer brake valve has three vents: one through cylinder, one through main vehicle, a brake valve, and one through disconnecting switch. When braking, the brake valve from the main vehicle to the compressed air into the trailer brake valve, close the air reservoir (wet air reservoir) the intake passage, cut off the gas supply, the trailer brake valve to switch the air separation tube in the compressed air is discharged rapidly
The function of the trailer brake valve is to cut off the gas supply pipeline of the trailer according to the driver's control, and meanwhile, the air supply pipe is connected with the atmosphere for braking.
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.
