Abstract
A kind of oil tank safety sealing device, comprise, oil tank wall, floating roof and the once sealing device be placed in oil tank wall and floating roof cavity, it is characterized in that: the top of oil tank wall side, once sealing device is provided with sealant tape, in the sealant tape inside of toroidal cavity, isocyanurate foam is housed, be fixed with L-type pressing plate, sealant tape one side with oil tank wall together with the tight docile of once sealing device, its sealant tape one end is locked by bolt A and secondary seal rubber flap, and the other end is locked by bolt B and floating roof top.The utility model eliminates the annular space of once sealing and secondary seal, can not cause explosive combustion, thus play fireproofing function, eliminate potential safety hazard.Enhance the sealing effectiveness of secondary sealer, break the form only leaning on rubber flap and oil tank wall to seal of traditional secondary sealing arrangement.Greatly reduce the loss of oil gas, serve great role to economy, safety, environmental protection.
Description
Technical field
The utility model relates to a kind of sealing arrangement, particularly a kind of oil tank safety sealing device.
Background technology
At present, known sealing arrangement, as Chinese utility model patent, the patent No. is 201120400005.5 disclose a kind of explosion suppression type floating roof tank floating plate sealing arrangement, comprise once sealing device, secondary sealer and block blast-proof materials, the cavity between once sealing device and secondary sealer filled by block blast-proof materials, wrapped up and be fixed on floating plate by wire gauze.Its drawback is, block blast-proof materials is filled to the cavity between once sealing device and secondary sealer, has just carried out filling effect to its cavity, but has not had the effect of one sealing.Thoroughly do not eliminate the cavity formed between once sealing device and secondary sealer.
Summary of the invention
For the deficiency that above-mentioned technology exists, the purpose of this utility model is to provide a kind of oil tank safety sealing device.
A kind of oil tank safety sealing device, comprise, oil tank wall (1), floating roof (6) and the once sealing device (5) be placed in oil tank wall (1) and floating roof (6) cavity, it is characterized in that: in oil tank wall (1) side, the top of once sealing device (5) is provided with sealant tape (3), in sealant tape (3) inside of toroidal cavity, isocyanurate foam (4) is housed, be fixed with L-type pressing plate (8), sealant tape (3) one side is together with oil tank wall (1) and the tight docile of once sealing device (5), its sealant tape (3) one end is locked with secondary seal rubber flap (2) by bolt A (7), the other end is locked by bolt B (11) and floating roof (6) top.
Described isocyanurate foam (4) is used for supporting sealant tape (3), makes sealant tape (3) and oil tank wall (1) and once sealing device (5) closely docile.
Described L-type pressing plate (8) is locked by bolt B (11) and floating roof (6) top.
Be fixed with secondary seal bearing plate (9) in the bottom of secondary seal rubber flap (2) by bolt A (7), the lower end of its secondary seal bearing plate (9) is locked on the top of floating roof (6) by groove type press strap (10) afterwards through bolt B (11).
The beneficial effects of the utility model are: 1. the annular space eliminating once sealing and secondary seal, can not cause explosive combustion, thus play fireproofing function, eliminate potential safety hazard.2. strengthen secondary seal effect: compressing sealant tape (3) makes its docile in once sealing device (5) top and oil tank wall (1) side downwards, make the sealing effectiveness which increasing secondary sealer, break the form only leaning on rubber flap and oil tank wall to seal of traditional secondary sealing arrangement.3. compared with known technology, add a road sealing device, thus greatly reduce the loss of oil gas, serve great role to economy, safety, environmental protection.
Accompanying drawing explanation
Fig. 1 is cross-sectional side sectional structure schematic diagram of the present utility model.
In figure: oil tank wall 1, secondary seal rubber take scraper plate 2, sealant tape 3, isocyanurate foam 4, once sealing device 5, floating roof 6, bolt A7, L-type pressing plate 8, secondary seal bearing plate 9, groove type press strap 10, bolt B 11.
Detailed description of the invention
As shown in Figure 1, a kind of oil tank safety sealing device, comprise, oil tank wall 1, floating roof 6 and the once sealing device 5 be placed in oil tank wall 1 and floating roof 6 cavity, it is characterized in that: the top of oil tank wall 1 side, once sealing device 5 is provided with sealant tape 3, in sealant tape 3 inside of toroidal cavity, isocyanurate foam 4 is housed, is fixed with L-type pressing plate 8, its L-type pressing plate 8 is locked by bolt B 11 and floating roof 6 top.Sealant tape 3 and oil tank wall 1 are together with once sealing device 5 closely docile, and its sealant tape 3 one end is locked by bolt A7 and secondary seal rubber flap 2, and the other end is locked by bolt B 11 and floating roof 6 top.
Be fixed with secondary seal bearing plate (9) in the bottom of secondary seal rubber flap (2) by bolt A (7), the lower end of its secondary seal bearing plate (9) is locked on the top of floating roof (6) by groove type press strap (10) afterwards through bolt B (11).
