The invention aims to provide the serial spring type flame suppressor which has the advantages that the valve is not easy to damage, the reliability is high, and the service life is longer. The series spring type flame suppressor comprises: a housing; the overpressure valve is arranged in the shell; the negative pressure valve is arranged outside the shell; the overpressure valve and the negative pressure valve are installed on the fixing shaft in the mode that the overpressure valve and the negative pressure valve can slide in the axis direction, and an inner limiting spring and an outer limiting spring which can stretch out and draw back in the axis direction are arranged on the fixing shaft in a series connection mode. The internal limiting spring is used for abutting against the overpressure valve to limit the sliding range of the overpressure valve on the fixing shaft, and the external limiting spring is used for abutting against the negative pressure valve to limit the sliding range of the negative pressure valve on the fixing shaft.
