Description
Relate to the field
The utility model relates to a kind of floating top of flexible double plate that is used for vertical steel soldering oil jar, belongs to oil tank floating roof structure technical field, is used for vertical steel soldering oil jar.
Background technology
The floating outward top of vertical steel soldering oil jar has single-deck formula and two kinds of versions of double plate usually, and its merits and faults is respectively arranged.Single-deck formula floating roof structure is simple, and is in light weight, saves steel, and fabrication cost is low, and the ponding rear stability is good thereby the resistance to sinking energy is strong; But owing to be single-deck, its heat-insulating property difference and difficult realization insulation, heat dissipation capacity is big, wastes energy, and the single-deck distortion is big, and easy ponding is corroded easily, and single-deck is originally as a fexible film, and anti-high wind is poor than double plate; The floating top of double plate good heat insulating, top board is little with respect to the single-deck distortion, it is good to be difficult for ponding thereby antiseptic property, but shortcoming in general its ponding rear stability is bad, thereby resistance to sinking is poor, complex structure, weight is big, waste steel, fabrication cost height.
Technology contents
It is resistance to sinking that the purpose of this utility model is to provide a kind of existing good ponding stability, and good insulation, the floating top of flexible double plate anticorrosion, anti-high wind are arranged again.
The purpose of this utility model is achieved in that
Comprise outer shroud cabin 1, flexible base plate 2, bracing frame 3, top board 4, heat-insulation layer 5, hoop trough 6, central authorities' trough 7, connection pipe 8, catch pit 9, check valve 10, floating roof drain 11 and urgent drainage mechanism 12, breather pipe 13, the Fu Ding border is mutual fully enclosed outer shroud cabin 1, flexible base plate 2 peripheries are welded on 1 inboard, outer shroud cabin, bracing frame 3 is placed on the flexible base plate 2, top board 4 is fixedly connected on the bracing frame 3, heat-insulation layer 5 is arranged on the top board 4, the hoop trough connects 6 and is connected on 1 inboard, outer shroud cabin, central authorities' trough 7 places flexible base plate 2 middle parts, hoop trough 6 is linked to each other by connection pipe 8 with central trough 7, inside and outside central authorities' trough 7 catch pit 9 is set all, check valve 10 is set in the catch pit 9, check valve 10 links to each other with floating roof drain 11, and urgent drainage mechanism 12 is installed on the flexible base plate 2, and breather pipe 13 is installed on the top board 4.
The utility model also adopts following technical scheme:
Top board 4 can be taper or sphere shape, can also be the hoop arch.
The utility model uses as outer floating top, the top board and the heat-insulation layer on top play insulation effect, the single-deck of bottom plays the effect of accumulating rainwater, precipitation is by flowing into the hoop trough on the top board (when top board is annular roof plate, there is part precipitation to flow directly into central trough), flow into central trough by connection pipe, flow into central catch pit then, by check valve by outside the floating roof drain drain tank.The water of or other reason central authorities trough big when moisture conditions is when in time drain tank is outer, and water overflows on the outer flexible base plate of groove, makes flexible base plate produce high camber, and high camber makes ponding concentrate on middle part, floating top and center of gravity reduces, and floats and offends and disobey with rude remarks the performance enhancing of toppling; When the water on the single-deck surpasses the permission water accumulating volume on floating top, enter in the jar by the urgent freeing arrangement ponding that will overload, thereby protected the safety on floating top; Top board and heat-insulation layer can play the effect of insulation again simultaneously; Moisture conditions is little generally speaking, and water flows directly into central trough, long-term no ponding on the single-deck, thereby alleviated the corrosion on floating top greatly.
The utlity model has following advantage: precipitation concentrates on the flexible base plate, floating top good stability, thereby resistance to sinking is strong; Top board and heat-insulation layer have increased heat-insulating property, can save the energy; Long-term no ponding is gone up on floating top, has alleviated corrosion; More common double plate is simple in structure, and convenient construction is in light weight, can save construction investment, reduces use cost.
