The invention discloses a pressure water-storage device sealing structure. The pressure water-storage device sealing structure comprises an outer shell, an elastic liner and a pipe joint. The elastic liner is located in the outer shell, an aeration cavity is formed between the elastic liner and the outer shell, and a water outlet is located in an opening; the pipe joint is provided with a water inlet channel, a water outlet channel and an aeration opening; the water inlet channel and the water outlet channel are both communicated with the water outlet; the pipe joint is connected with the upper end of the outer shell, and the elastic liner is compressed to the upper end of the outer shell; a first annular groove is formed in the outer edge of the upper end of the outer shell, and a first seal ring is disposed in the first annular groove; a second annular groove is formed in the inner wall of the opening of the outer shell, and a second seal ring is disposed in the second annular groove; expansion chambers are formed in both the first seal ring and the second seal ring; air inlet holes communicated with the expansion chambers are formed in the first seal ring and the second seal ring; air channels communicated with the air inlet holes of the first seal ring and the second seal ring are formed in the outer shell. By means of the pressure water-storage device sealing structure, a pressure water-storage device is good in airtightness, and leakage of compressed gas in the aeration cavity can be prevented.
