<p>PURPOSE:To prevent tank breakage when sloshing happens in a ship body by aggrandizing a difference between tank inside pressure and interbarrier space pressure and pressing the tank wall strongly to the secondary barrier with the differential pressure utilized. CONSTITUTION:An ejector 10 is actuated by a compressed air A, inhaling air of an interbarrier space 8. Like this, pressure of the interbarrier space 8 is always kept less than atmospheric pressure, differential pressure with pressure inside the tank is made large and, by this difference, the wall of a tank 5 is strogly pressed to a secondary barrier 9 so that even if sloshing phenomenon happens in a ship body, the tank 5 is supported by the ship body 1 through the secondary barrier 9 whereby no breakage will happen.</p> |
