| 摘要 | PURPOSE:To reduce the amount of water used and to reduce the amount of antifreezing agent by disposing an outer tank filled with water between an inner cylinder and an outer cylinder, and disposing a float tank in the outer tank. CONSTITUTION:An outer tank 5 filled with water is disposed between an inner cylinder 6, the upper end of which is closed, and an outer cylinder 7, and a freely floating float tank 8 is disposed in the outer tank. A weight 9 is mounted on the lower end of the float tank 8 to keep gas pressure constant, and an outlet/ inlet pipe 10 for gas is disposed on the top surface of the inner cylinder 6. The outer tank 5 is of a double-cylinder structure, so that the sealed water is a small quantity. Accordingly, an antifreezing agent mixed in water may be a small quantity to reduce the running cost. At the initial operation of a gas tank, if the float tank 8 is placed at the lowermost position, as the inner cylinder has a raised bottom, a space between the float tank 8 and the inner cylinder 6 is very small, and the air to be substituted in the float tank 8 is a little, so that substitute gas may be a little quantity to improve the efficiency of substitute work. | ||||||
