The purpose of this utility model is to be to provide a kind of being convenient to make, safeguard that can guarantee is not again influencing under the oil tank ordinary production situation, changes the floating top of the inside and outside buoyancy module formula of external floating top tank single-deck fast.
The purpose of this utility model is to realize like this, the floating top of the inside and outside buoyancy module formula of external floating top tank single-deck, comprise floating top edge buoyancy module, single-deck and foam dam, it is characterized in that: floating top edge buoyancy module is connected by bolt arrangement with fan-shaped plate by fan-shaped plate and surrounds belt buoyancy module; Each quadrant of edge buoyancy module and annular slab connect into the cross section by bolt arrangement and are " h " shape, seal by ring seal between fan-shaped plate and the annular slab; Annular slab horizontal-extending to the inside is connected by bolt arrangement with single-deck.Described single-deck central authorities are connected with central removable buoyancy module by bolt arrangement.
The removable buoyancy module in described middle part is to connect into belt buoyancy module by fan-shaped plate by bolt arrangement.
The removable buoyancy module of described central authorities is an integral type.
Described single-deck can be to be connected as one by bolt arrangement by plate and plate, and the joint close face of plate and plate has face seal.
Be provided with radial seal between the described fan-shaped plate joint face.
Be welded with foam dam on the described floating top edge buoyancy module, soft seal is adopted in the gap between the foam dam on the floating top edge buoyancy module.
There is sealing gyratory intersection joint with annular slab between the described floating top edge buoyancy module.
Joint face has vertical connection side between described fan-shaped plate and the fan-shaped plate, between the vertical connection side radial seal is arranged, and is connected by bolt arrangement between the vertical connection side again.
Characteristics of the present utility model are: floating top edge annular buoyancy module, the removable buoyancy module in middle part (or central removable buoyancy module) are designed to the piecemeal formula by single buoyancy module, and plate plate and all buoyancy modules adopt bolted connection, and all junctions are provided with special hermetically-sealed construction.The whole batch production of manufacturing work on floating top can reduce field activity greatly, improve workman's work situation; In service if certain buoyancy module leakage in floating top can be prefabricated in the factory earlier, is transported to on-the-spotly directly to change, thereby has avoided the safety that traditional floating top causes because of maintenance and the stopping production problem of oil tank, guarantees the oil tank long-term use.
