摘要： PURPOSE:To lower production cost of storage tank by providing a number of division plates between the shell plates of a tank, thus constituting pressure control chambers and by communicating the pressure control chambers to a pressure medium source through a pressure control valve. CONSTITUTION:Pressure control chambers 2 are produced by installing division plates 1 between the shell plates 5 and 8 of a multicore storage tank. The pressure control chambers 2 are communicated to a pressure medium header 19 through a pressure control valve 4. This construction allows the pressure control valve 4 to control the pressure in the pressure control chambers 2 responding to the differential pressure produced therein so that the differential pressure may be minimized. As a result the construction makes it possible to reduce the thickness of shell plates and to fabricate division plates 1 with smaller rigidity and to minimize weld penetration, thereby reducing production cost of storage tank sharply.

摘要： PURPOSE:To prevent evaporation loss of oil, inflammation trouble, etc., by placing a pressure gauge etc. under a fixed roof and controlling water pressure so as to constantly bring the roof into close contact with oil, in an oil-water replaceable tank for storing crude oil etc. solid at normal temp. CONSTITUTION:An oil-water replaceable tank for storing, in solid state, crude oil, heavy oil, etc. solid at normal temp. is filled with water, and then a predetermined amt. of a liquid oil is introduced via distributer 6 and stored by replacing the water. A vapor zone formed with solidification and shrinkage of the liquid oil, is detected by pressure gauge or stress gauge 8 placed under the roof 2, and pressure control valve 9 is automatically opened corresponding to the signal of detection, applying a required pressure on water tank 3 from pressure medium tank 10, so that the oil is raised and brought into close contact with the roof 2, making the vapor zone disappear. Thus the oil is prevented from vaporizing.
