Abstract

The invention discloses a trailer control valve of a port mechanical brake system. The trailer control valve of the port mechanical brake system is provided with a valve body and a piston; the valve body of the trailer control valve is provided with an air inlet connected a switch valve, a first air inlet connected with a foot valve, a second air inlet connected with the foot valve, a first air outlet and a second air outlet; the first air outlet is connected with a trailer manual brake connector; the second air outlet is connected with a trailer foot brake connector; the air inlet connected with the switch valve communicates with the second air outlet; a valve port is formed in the position where the piston and the valve body make contact with each other; under the function that a spring pushes the piston, the valve port is closed; and under the air pressure function of the air inlet connected with the switch valve, the valve port is opened, and air paths of the first air inlet connected with the foot valve, the second air inlet connected with the foot valve and the first air outlet communicate with one another. By the adoption of the technical scheme, the two valves are integrated into one valve, the product structure is simplified, the production period is shortened, the product capacity and performance are improved, and the product production cost is greatly lowered.

Description

technical field [0001] The invention belongs to the technical field of port mechanical equipment, and relates to the brake system technology thereof. More specifically, the present invention relates to a trailer control valve for a port machinery braking system. Background technique [0002] In the prior art, the mechanical brake system of the port is a valve jointly controlled by the foot brake valve and the manual brake valve to realize the brake of the trailer. It weighs 2.3kg and has a volume of 146×138×188. The M8 is fixed to the chassis of the tractor. [0003] The trailer control valve described above has complicated structure, heavy weight, and inconvenient installation and connection. Contents of the invention [0004] The invention provides a trailer control valve for a mechanical brake system of a port, and its purpose is to simplify the structure of the control valve. [0005] In order to achieve the above object, the technical scheme that the present invent...
