Abstract
PURPOSE: To improve the efficiency of liquid filling and exhausting, by fixing a floating-roof type tank in a concrete case and forcibly adjusting the sealing water filled in the clearance between the side plate and the case wall and also inside the tank being communicated with the case.
CONSTITUTION: A floating-roof 10''' equipped with floats 15 of a tank 10 vertically moves along a side plate 10' as the level of sealing water 14 varies. When the sealing water 14 increases by exhausting oil 4 stored, the level of the sealing water 14 in the clearance h is adjusted to the level the underground water 8 by means of a pump 12. For improving the exhaust pressure against the oil 4, the sealing water is increased in the clearance h by the pump 12 to increase water as a water bed in the tank 10.
