Abstract
Provided is an alternative automatic negative pressure water sealing drainage apparatus. A lower one-way valve is installed on a sealing separation plate at the upper end of a tank body, a water sealing tube is arranged in the tank body, and the upper end of the water sealing tube penetrates through the sealing separation plate at the upper end of the tank body to be connected with the lower end of a connecting tube. A stretchable drainage apparatus is connected with the position above the sealing separation plate at the upper end of the tank body, the upper portion of the lower one-way valve is communicated with a cavity of the stretchable drainage apparatus, a spring is arranged in the stretchable drainage apparatus, an air discharge nozzle is arranged on an upper cover of the stretchable drainage apparatus, an upper one-way valve is arranged in the air discharge nozzle, a liquid inlet is arranged on the upper cover of the stretchable drainage apparatus, an upper end for connecting with the connecting tube is arranged on a lower port of the liquid inlet of the stretchable drainage apparatus, and the upper end of the liquid inlet is connected with a drainage tube. A joint is arranged at the front end of the drainage tube, and a water stopping valve is arranged on the drainage tube. A clear liquid plugging cap is arranged at the bottom of the tank body. The alternative automatic negative pressure water sealing drainage apparatus enables an inside of a drainage bottle and an outside to be sealed, avoids polluting the environment, does not need a negative pressure source, and can produce drainage negative pressure through manual operation.
