Description
Technical field
The utility model relates to floating roof tank floating plate sealing arrangement, is specifically related to a kind of secondary sealer that can be applicable to External floating roof tank and internal floating roof tank.
Background technology
Current, floating roof tank all requires to install secondary sealer.Secondary sealer is made up of metal bearing plate, oil gas barrier film, static conductive sheet, rubber plate etc.Oil gas barrier film and rubber plate are fitted on tank skin by metal bearing plate by this device, but this device exists obvious safety problem.1, between once sealing device and secondary sealer, oil-gas space is comparatively large, and metal bearing plate expands outwardly, and makes inner space very large, and for 100,000 vertical storage tanks, this spatial volume can reach 50m
3-60m
3; 2, metal bearing plate because mounting means impact and finite elastic, tank skin distortion after, between secondary seal metal profile and tank skin, adhesive force reduces, and even may depart from tank skin, and this can cause oil and gas leakage; 3, hidden danger of striking sparks of being struck by lightning is had between metal bearing plate and storage tank shell.
Utility model content
In order to solve in prior art that having between metal bearing plate and storage tank shell is struck by lightning and strike sparks the problem of hidden danger, the utility model provides a kind of floating roof tank secondary sealer of sparking hidden danger of can avoiding being struck by lightning.
Floating roof tank secondary sealer, comprise oil gas barrier film and tilted-putted metal profile, described metal profile is made up of upper plate, central panel and lower plate from top to bottom successively, and described upper plate, central panel and lower plate are one-body molded; The outside horizontal buckling of described upper plate, upper plate is fixed with rubber plate; Described rubber plate is inverted L-shaped, and rubber plate is made up of the compartmented of horizontal linkage section and vertical shape, and linkage section and upper plate are bolted; Compartmented is between storage tank outer wall and central panel; The upper end of described oil gas barrier film is fixed on the top of upper plate, and the lower end of oil gas barrier film is fixed in lower plate.
Preferably, described lower plate upwards bends, and oil gas barrier film is connected by floating plate bolt with between lower plate, and described floating plate bolt is hollow.
Preferably, the contact surface of rubber plate and storage tank is provided with multiple well-distributed seal ring.
Preferably, described central panel is the arc to storage tank direction projection.
Preferably, described oil gas barrier film is provided with extension.
The utility model compared with prior art, has following beneficial effect:
Above-mentioned floating roof tank secondary sealer, the linkage section of rubber plate is connected with upper plate, the outside horizontal buckling of upper plate, the compartmented of rubber plate, between storage tank outer wall and central panel, can prevent metal profile and storage tank outer wall when being struck by lightning from occurring the spark phenomenon that is struck by lightning.Floating plate bolt is hollow, plays the effect of discharging ponding.The contact surface of described rubber plate and storage tank is provided with multiple well-distributed seal ring, seal ring can play the effect of sealing.Described central panel is the arc to storage tank direction projection, can increase the elasticity of metal profile.Described oil gas barrier film is provided with extension, can make oil gas barrier film under gravity, and the tank skin of laminating storage tank, reduces the oil-gas space between once sealing device and secondary seal, reduces the consequence that in oil-gas space, oil gas fires.
Accompanying drawing explanation
Fig. 1 is the cutaway view of floating roof tank secondary sealer.
1 rubber plate; 11 seal rings; 2 oil gas barrier films; 3 bolts; 4 metal profile; 5 floating plate bolts.
Detailed description of the invention
Below in conjunction with Fig. 1, the utility model is described in detail.
Floating roof tank secondary sealer, comprises oil gas barrier film 2 and tilted-putted metal profile 4, and described metal profile 4 is made up of upper plate, central panel and lower plate from top to bottom successively, and described upper plate, central panel and lower plate are one-body molded; The outside horizontal buckling of described upper plate, upper plate is fixed with rubber plate 1; Described rubber plate 1 is in inverted L-shaped, and rubber plate 1 is made up of the compartmented of horizontal linkage section and vertical shape, and linkage section is connected by bolt 3 with upper plate; Compartmented is between storage tank outer wall and central panel; The upper end of described oil gas barrier film 2 is fixed on the top of upper plate, and the lower end of oil gas barrier film 2 is fixed in lower plate.
Further, described lower plate upwards bends, and oil gas barrier film 2 is connected by floating plate bolt 5 with between lower plate, and described floating plate bolt 5 is hollow.Floating plate bolt 5 is hollow, plays the effect of discharging ponding.
Further, rubber plate 1 and the contact surface of storage tank are provided with multiple well-distributed seal ring 11.Described seal ring 11 can play the effect of sealing.
Further, described central panel is the arc to storage tank direction projection.The shape of described central panel can increase the elasticity of metal profile 4.
Further, described oil gas barrier film 2 is provided with extension.The setting of described extension, can make oil gas barrier film 2 under gravity, and the tank skin of laminating storage tank, reduces the oil-gas space between once sealing device and secondary seal.
Above-mentioned floating roof tank secondary sealer, after completing the installation of floating roof tank once sealing device, first oil gas barrier film 2 and metal profile 4 are stacked together, upper and lower two ends are fixed, and then by floating plate bolt 5, the floating plate on metal profile, oil gas barrier film and storage tank is fixed together, metal profile 4 put into afterwards, metal profile 4 relies on natural resiliency namely to conform to tank skin surface.Above-mentioned floating roof tank secondary sealer, the linkage section of rubber plate 1 is connected with upper plate, the outside horizontal buckling of upper plate, can prevent rainwater from falling into secondary sealer inside.The compartmented of rubber plate 1, between storage tank outer wall and central panel, can prevent metal profile 4 and storage tank outer wall when being struck by lightning from occurring the spark phenomenon that is struck by lightning.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
