The invention provides an empty and heavy vehicle adjustment valve for a vehicle air braking system. The empty and heavy vehicle adjustment valve comprises a valve body, a sensing part and a first switching part, wherein the valve body is provided with a cavity, a first passageway for communicating the cavity with a control valve, a second passageway for communicating the cavity with a pressure reduction air cylinder and a third passageway for communicating the cavity with a braking cylinder; the sensing part is mounted on the valve body and is provided with a sensing end and a control end; the control end is provided with different control end positions according to vehicle loading conditions sensed by the sensing end; the first switching part is arranged in the cavity and can be switched between a heavy load working position and an empty load working position according to the difference of the control end positions of the sensing part; at the heavy load working position, the control valve is communicated with the braking cylinder and is not communicated with the pressure reduction air cylinder; at the empty load working position, the control valve can be communicated with both the braking cylinder and the pressure reduction air cylinder. According to the empty and heavy vehicle adjustment valve, the problems of complicated connection pipelines among all components of the empty and heavy vehicle adjustment valve and large occupation space in the prior art can be effectively solved.
