Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
The present embodiment provides the sealing structures between a kind of interior floating plate and tank skin, as depicted in figs. 1 and 2, including sliding elastic force
Plate 301 and sealing diaphragm 302.As shown in figure 3, the one end and the interior floating plate of the sliding elastic plate 301 close to interior floating plate 100
100 are fixedly connected, and specifically can be and are connect by bolt with the enhanced margin plate of interior floating plate 100.Far from the interior floating plate 100
One end extend downwardly, and extend downwardly position be close to tank skin 200；Specifically, the length that interior floating plate 100 extends downwardly can be big
In equal to 100mm.Sliding elastic plate 301 described in muti-piece is end to end, covers between the interior floating plate 100 and the tank skin 200
Gap.The sealing diaphragm 302 is attached at the bottom surface of the sliding elastic plate 301, covers adjacent two pieces of sliding elastic plates
Gap between 301.
Sealing structure between interior floating plate and tank skin provided in this embodiment, including sliding elastic plate 301 and sealing diaphragm
302, wherein sliding elastic plate 301 is used as main seal structure, and one end is fixedly connected with interior floating plate 100, and the other end is to downward
It stretches, sliding elastic plate 301 has elasticity after extending downwardly, and allows to be tightly attached on tank skin 200.When tank body deformation is serious or outer
Power effect keeps interior floating plate 100 mobile, cause interior floating plate 100 between tank skin 200 at a distance from when becoming larger, slide elastic plate 301 with interior
Floating plate 100 moves together.The sliding elastic plate 301 protruded into liquid phase at this time moves up, and 301 length of elastic plate is slided in liquid
It shortens, but remains in a liquid.Again due to sliding elastic plate 301 have favorable elasticity, sliding elastic plate 301 always with tank
Wall 200 is kept in contact does not separate, so that oil-gas space is not present between interior floating plate 100 and tank skin 200, the effective guarantee sealing
The sealing effect of structure.Since storage tank is usually cylindrical shape, and it is relatively large in diameter, and interior floating plate 100 must be covered by sliding elastic plate 301
With the annular slot between tank skin 200, it is clear that use a monolith board making, difficulty is larger, higher cost, so the present embodiment
End to end using sliding elastic plate 301 described in muti-piece, production is more convenient simple, and manufacturing cost can be greatly lowered；This
Embodiment is also equipped with sealing diaphragm 302 in the bottom surface of sliding elastic plate 301, and sealing diaphragm 302 covers adjacent two pieces of slidings elastic force
Gap between plate 301 plays effective sealing function to the oil gas of volatilization, can be further improved whole sealing effect.
Optionally, as shown in figure 4, the sealing structure further includes elastic force pressing plate 303, the elastic force pressing plate 303 is close to interior floating
One end of disk 100 is fixedly connected with the interior floating plate 100, and one end far from the interior floating plate 100 is pressed on the sealing diaphragm
302 bottom surface.In the bottom surface of sealing diaphragm 302, elastic force pressing plate 303 is set, it can be to sealing diaphragm 302 and sliding elastic plate 301
Pressure is generated, fits closely sealing diaphragm 302 with elastic plate 301 is slided.
Wherein, as long as since elastic force pressing plate 303 plays the role of pressure to sealing diaphragm 302 and sliding elastic plate 301,
So the elastic force pressing plate 303 can slide elastic plate 301 with endless all standing, as long as being arranged at equal intervals in order to save raw material
Muti-piece.Specifically, 303 spacing of elastic force pressing plate can be 600mm or so.
Further, which further includes support plate 304, the support plate 304 close to interior floating plate 100 one end with
The interior floating plate 100 is fixedly connected, and one end far from the interior floating plate 100 is pressed on the bottom surface of the elastic force pressing plate 303.Rest
Plate 304 can effectively be enhanced, compensated and be adjusted to sliding elastic plate 301, to guarantee sliding elastic plate 301 and tank skin
Between 200 have the enough power of being adjacent to, thus guarantee the sealing structure sealing effect and good flatness.
Optionally, as shown in figure 5, in order to further increase the sealing effect of the sealing structure, which further includes
Secondary seal plate 305.The secondary seal plate 305 is fixedly connected close to one end of interior floating plate 100 with the interior floating plate 100, far
One end from the interior floating plate 100 is pressed on the tank skin 200, and is oppositely arranged with the sliding elastic plate 301.Setting two
Secondary sealing plate 305, not only further improves sealing effect, can also play certain compensating action to sliding elastic plate 301,
Reduce or offset to a certain extent the buoyancy that sliding elastic plate 301 is subject to.
Optionally, as shown in Figure 3 and Figure 5, the lower ora terminalis of the sliding elastic plate 301 upsweeps.Slide elastic plate
301 lower end forms arc groove, and when sliding the floating upwards of elastic plate 301, the liquid in groove produces sliding elastic plate 301
Raw certain resistance, so that sliding elastic plate 301 is contacted with liquid always.
Optionally, in order to guarantee to slide the elasticity and oil resistivity and corrosion resistance of elastic plate 301, sliding elastic plate 301 is selected
With sheet metal, it is specifically as follows the stainless steel plate of thick 0.3mm~0.7mm, preferably thickness 0.5mm.
Optionally, in order to further ensure the sealing effect of the sealing structure, the sealing diaphragm 302 is one whole, first
Tail overlap joint, and one end far from the interior floating plate 100 is shorter than the sliding elastic plate 301.In this way, seam is reduced, it can be into one
Reduced volatilization is walked, to improve the sealing effect of sealing structure.
Optionally, the material of the sealing diaphragm 302 is the anti-aging high molecular material of oil resistant.Since sealing diaphragm 302 is long
Phase contacts with oil liquid, so the material of sealing diaphragm 302 is the anti-aging macromolecule material of oil resistant.
Optionally, due to coating the glass fabric of polytetrafluoroethylene ethylene layer, -70 DEG C~+400 DEG C of heatproof, and acidproof alkali soluble
Liquid and a variety of organic solvents, have excellent weather resistance, and tension failure strength, extension at break and Tear strength are also not less than JC/T171.2
Specified in I class requirement.So the sealing diaphragm 302 is including glass layer and is coated in the glass fibre layer surface
Polytetrafluoroethylene ethylene layer.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
