The invention relates to a check ash valve used for a sound wave ash blower. The check ash valve comprises a valve body, an upper valve element, a lower valve element, a valve seat assembly, a sliding rod and a flange plate. When airflow and sound waves enter the check ash valve, the valve elements are pushed open under the action of the airflow, the check ash valve is opened, and the sound waves and the airflow bring away smoke, small particles and the like through the check ash valve. When the pressure of the airflow is reduced or the airflow stops, the valve elements fall under the action of gravity, the lower valve element makes contact with the valve body, the check ash valve is closed, smoke and the like which flow back cannot enter the check ash valve, and it is ensured that a sound wave generation device is not corroded by smoke which flows back. A sound impedance matching technology and a damping sound insulation and noise reduction technology are adopted for the check ash valve, the problem of noise leakage in the working process is solved, it is ensured that sound wave energy is effectively transmitted, energy losses are reduced, and it is ensured that the sound wave ash blower runs safely and efficiently.
