The trailer control valve is also called trailer brake valve. The function is to cut off the gas supply pipeline of the trailer according to the driver's control, and connect the gas supply pipeline with the atmosphere to brake. The trailer brake valve has three ventilation ports: one through storage tank, one through main vehicle brake valve and one through disconnect switch. When the car is braking, the compressed air from the main brake valve of the main car enters the brake valve of the trailer, closes the inlet channel of the storage cylinder (wet storage cylinder) and cuts off the gas source, so that the compressed air of the trailer brake valve to the separation switch air pipe is quickly discharged. At this time, the distribution valve on the trailer stops the compressed air in the storage tank of the trailer and enters the brake chamber of the trailer, resulting in braking effect with the main vehicle. When the brake pedal is relieved, the compressed air from the main vehicle brake valve is discharged into the air, and the trailer is released at the same time.
