The invention relates to a working valve block and a braking energy supply system, the working valve block comprises an oil inlet valve, an energy accumulator and a three-way valve, the energy accumulator communicates with the oil inlet valve and the three-way valve, pressure oil can enter the energy accumulator through the oil inlet valve, the pressure oil can leave the energy accumulator through the three-way valve, and a sealing valve is further arranged between the three-way valve and the energy accumulator. The sealing valve is used for controlling on-off of the three-way valve and the energy accumulator. According to the working valve block and the braking energy supply system, the problem that a three-way valve is prone to leakage is solved.
