Abstract
A floating roof of a tank for storing liquids consisting of a resilient disc-shaped diaphragm attached, leakproof fashion, all the way around its circumference to an annular seal and further attached to a floating chamber at the center which is fitted to an upright with provision for displacing along same when the level of liquid is changing. The resilient disc-shaped diaphragm is made hollow and is corrugated in the radial and circumferential directions so that the corrugations form a plurality of cells. The diaphragm rests on a series of radially disposed telescopic arms each attached with one of its ends to the floating chamber and resiliently connected at its free end to the annular seal. A rool of this type can practically be used with tanks of any shape.
Claims4
A floating roof of a tank for storing liquids, with an upright centrally secured therein, comprising a floating chamber fitted to said upright of said tank with provision for displacement along the upright when the level of liquid in the tank is changing;
- a space inside said floating chamber filled with a gaseous fluid under an excess pressure;
- an annular seal the outward edge whereof is in contact with the shell of the tank;
- said annular seal comprising a plurality of members pivotally interlinked one with another;
- a resilient disc-shaped diaphragm attached, leakproof fashion, to said floating chamber at the centre and to said floating seal all the way along its circumference;
- said resilient disc-shaped diaphragm made hollow and corrugated in the radial and circumferential directions;
- a plurality of cells formed by the corrugations of said resilient disc-shaped diaphragm;
- said plurality of cells enabling the disc-shaped diaphragm to expand up to the shell of the tank in all transverse directions when the level of liquid in said tank is changing;
- a framework resting whereon is said resilient disc-shaped diaphragm, said framework consisting of a plurality of radially disposed telescopic arms each attached with one of its ends to said floating chamber and resiliently connected at its free end to said annular seal.
