The invention relates to a brake relay valve regulator. The brake relay valve regulator is characterized in that two cylinders are included, a valve return spring is installed in a valve containing chamber located on the outer side of a valve of the main cylinder, and a valve fixing pressing piece is arranged in a valve containing chamber located on the outer side of a valve of the auxiliary cylinder, so that the valve of the auxiliary cylinder can be in a closed state all the time; an exhaust channel is formed in the centers of a big piston, a small piston and a valve ejector rod of the auxiliary cylinder, and the big piston, the small piston and the valve ejector rod are closely and sequentially connected; two air cylinders of the cylinders are connected and communicated with an air outlet of a relay valve through a big air cylinder tee joint, and two small air cylinders of the cylinders are connected and communicated with a piston stabilizing chamber of the relay valve through a small air cylinder tee joint. The brake relay valve regulator has the advantages that the brake pressure output by the brake relay valve can be gradually and steadily increased according to the input air pressure, therefore, a vehicle can be steadily braked, the vehicle can be firmly braked steadily and hastily even through hard braking is performed, safety and reliability are achieved, the performance is good, and traffic accidents can be greatly reduced; the brake relay valve regulator is high in cost performance, economical, practical and obvious in social benefit.
