Technical field
This utility model is related to a kind of sealing device and in particular to a kind of floating roof tank torsionspring foamed plastic form is close
Seal apparatus.
Background technology
Floating plate edge seal is that Large Oil Tank controls one of most important device of oil gas volatilization, after sealing,
The volatilization loss of oil product can be reduced in a large number.Floating plate edge seal is mainly made up of two parts: once sealing and secondary seal, and one
Inside the secondary annular space being sealingly mounted between floating plate and tank skin, usual and oil product directly contact.In order to reduce oil further
Product evaporating loss, adds a set of sealing device, i.e. secondary seal above original once sealing.
Once sealing is broadly divided into three types: mechanical seal, elastic soft sealing and tubular type topping up according to the difference of structure
Sealing.Mechanical seal is complicated due to internal structure, is likely to occur electric discharge in thunderbolt, leads to occur at edge seal hot
Fried accident.And, for the more serious storage tank of tank skin deformation, when device cannot meet seal request, can be in seal shoe plate and tank
Between wall formed must gap, do not only result in oil gas volatilization, and easily formed discharging gap when being struck by lightning.Elasticity is soft close
Envelope has that structure is simple, inside no metal parts (gap discharge will not occur during thunderbolt), preferably etc. excellent to tank skin deformation adaptability
Point.The mounting means of immersion type is generally taken in existing flexible foam sealing, rubber bag occurs after long-time use
The logy phenomenon of aging, filling sponge, and above sealing and secondary seal oil gas barrier film between, have larger oil
, still there is the possibility that Fire explosion occurs headroom when storage tank is struck by lightning.
Utility model content

The beneficial effects of the utility model are:
Above-mentioned sealing device includes bearing, torsionspring, support bar, sponge fixed plate, angle steel, rubber seal tape, rubber
Band and sponge, sealing is using the mounting means of immersion type.Rubber seal tape used is made using nitrile rubber, nitrile rubber
There is static conductive function, metal material should be zinc-plated structure.It is not enough that this sealing device solves foam seal structural elasticity
Problem, can adapt to the requirement of storage tank shell more large deformation, and, the oil gas that this sealing eliminates in floating plate marginal gap be empty
Between, can effectively reduce the generation of sealing ring fire incident.By using this sealing structure, particularly on External floating roof tank, right
In the serious storage tank of tank skin deformation, this sealing has the advantages that Flexible change is big, and deformation can meet gap and change r's (- x/+3x)
Require.And the part of inside configuration is isolated from the outside using rubber strip and comes by this sealing, it is allowed to inside and cannot produce oil gas
Space, it is to avoid occur the possibility of sealing ring fire incident inside sealing structure.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail:
In conjunction with Fig. 1 to Fig. 7, a kind of floating roof tank torsionspring foamed plastic form sealing device, including bearing 1, reverses
Spring 2, support bar 3, sponge fixed plate 4, angle steel 5, rubber seal tape 6, rubber band 7 and sponge 8.One end of described bearing 1
It is fixed on the top of floating plate margin plate 9, described floating plate margin plate 9 is floating roof tank floating plate edge present in prior art
Plate.The other end of described bearing 1 connects torsionspring 2 and support bar 3 by first rotating shaft, in 2 prior arts of torsionspring
Stress torsionspring.Described support bar 3 is made up of the body of rod 31 and the first contiguous block 32, and the left side connection of the bottom of the body of rod 31 is convex
The first contiguous block 32 going out.The side of the first contiguous block 32 in described support bar 3 passes through the second rotating shaft and connects sponge fixed plate
4.The right side of the bottom of the body of rod 31 is connected with rubber mat plate 33, and described rubber mat plate 33 is located at the front-right of the first contiguous block 32,
When support bar 3 plumbness, the bottom of support bar 3 is passed through rubber mat plate 33 and is connected with floating plate margin plate 9 support.
Described sponge fixed plate 4 is made up of plate body 41 and the second contiguous block 42, and the side at the middle part of plate body 41 connects protrusion
The second contiguous block 42, described second contiguous block 42 passed through the second rotating shaft and is connected with the first contiguous block 32 rotation.Described sponge is solid
The side setting angle steel 5 of fixed board 4, rubber band 7 and sponge 8, described angle steel 5 includes angle steel 51 and lower angle steel 52, upper angle steel
The 51 top sides being fixed on sponge fixed plate 4, lower angle steel 52 is fixed on the bottom side of sponge fixed plate 4.
Described rubber band 7 is made up of nitrile rubber, the lower surface of the outer face on the top of rubber band 7 and upper angle steel 51
It is connected, the outer face of bottom of described rubber band 7 is connected with the upper surface of lower angle steel 5, the side end face of sponge fixed plate 4.Institute
State in 7 in rubber band and be filled with sponge 8, sponge 8 is elastic sponge, sponge 8 is filled in rubber band 7.Described rubber is close
Envelope band 6 includes band 61 and lower band 62, and the bottom of upper band 61 is tightly connected with the upper end of upper angle steel 51, upper close
