The safety pressure regulating device is provided with two parallel main oilway electromagnetic valves and two parallel secondary brake oil supplementing electromagnetic valves between a hydraulic station oil tank and a brake oil tank so as to provide redundancy protection. An overflow valve and a safety pressure limiting overflow valve are respectively connected with the main oilway electromagnetic valves and the secondary brake oil supplementing electromagnetic valves to regulate oil pressure. A proportional overflow valve is connected with the main oilway electromagnetic valves to control oil pressure providing for a disc brake so as to realize constant deceleration. By the constant-deceleration hydraulic station system, oil pressure of the disc brake can be regulated automatically to allow an elevator to obtain different braking torque and perform deceleration brake according to setting. If constant-deceleration safety brake fails, the constant-deceleration hydraulic station system can automatically switch to a secondary brake manner.
