Abstract
The utility model discloses a roller sealing device for metal roof. The sealing device comprises a floating roof and a guide tube vertically penetrated through the floating roof. The floating roof comprises a lower boarding plate positioned at the external part of the guide tube, a double-layer rubber bearing and a fixation plate which are positioned sequentially from the bottom to the top of the upper part of the lower boarding plate and a foam bearing positioned between the double layers of the double-layer rubber bearing. The fixation plate is equipped with a guiding bar. The guiding bar comprises a plurality of pairs of connector which surround the periphery of the guide tube and are evenly distributed on the fixation plate, and a plurality of rollers which are respectively positioned on each pair of connector via a roller shaft. The number of connectors is three to eight pairs, and the numbers of the roller and the roller shaft are all three to eight. The roller sealing device for metal roof has the advantages of the reasonable structure, the reliable guidance, ensuring the good sealing and simultaneously maintaining the stable and vertical ascending and descending of the floating roof, and has substantive features and improvement by comparing to that of the existing technology.
Description
Technical field
The utility model relates to a kind of internal floating roof tank, and in particular, the utility model relates to a kind of metal roof sealing arrangement that is used for internal floating roof tank.
Background technology
Because internal floating roof tank is compared with the vault storage tank, the boil-off loss that can reduce liquid storage also can effectively reduce atmospheric contamination more than 95% simultaneously, and therefore, range of use is more extensive.Metal roof (being generally aluminum products and stainless steel products) belongs to a kind of of inner floating roof, it be arranged on tank inside and can be with the ascending, descending of medium liquid level in the storage tank upper and lower unsteady top.Those skilled in the art know that all when gauging conduit, radar level gauge wave guide or servo liquid meter protection sleeve were set, various gauge pipes were all wanted vertically to stay in the storage tank for a long time by floating top and as the part of instrument in internal floating roof tank.Existing metal roof all is in the junction of floating top and gauge pipe a simple sealing arrangement of means to be set, the upper and lower of floating top floats then by other steel wire guiding, therefore, can not guarantee good guide function, influence the upper and lower unsteady stability in floating top.
The utility model content
Problem to be solved in the utility model overcomes the above deficiency that prior art exists exactly, provide a kind of be used for metal roof, not only can guarantee good sealing effectiveness, but also can keep the stable vertical uplift in floating top and the roller sealing arrangement of decline simultaneously.
The utility model is used for the roller sealing arrangement of metal roof, comprise floating top and the vertical guide pipe that passes floating top, described floating top comprises and is arranged on the exterior down coaming plate of described guide pipe, the described upper end of coaming plate down is sequentially set with double-layer rubber pad and adapter plate from bottom to top, be provided with foam pad between the bilayer of described double-layer rubber pad, on described adapter plate, also be provided with ways, described ways by around described guide pipe circumference uniform distribution on described adapter plate some to attaching parts and respectively by rolling shaft be installed in described each the scroll wheel on the attaching parts is constituted.
Described attaching parts is 3～8 pairs, and described scroll wheel and rolling shaft are 3～8;
Described attaching parts is 6 pairs, and described scroll wheel and rolling shaft are 6.
The utility model is used for the roller sealing arrangement of metal roof, because on the basis of existing technology, be provided with the ways that constitutes by attaching parts, rolling shaft and scroll wheel, obtained all good beneficial effect of leak tightness and guidance quality, had substantive distinguishing features and progress than prior art.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to view.
The specific embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is done to describe in detail:
Fig. 1, Fig. 2 have illustrated formation situation of the present utility model with the A of front view and front view to view respectively.As seen from the figure, the utility model is used for the roller sealing arrangement of metal roof, comprise floating top 9 and the vertical guide pipe 6 that passes described floating top 9, described floating top 9 is by being centered around described guide pipe 6 exterior coaming plates 1 down, being set in sequence in the described foam pad 2 that descends double-layer rubber pad 3, the adapter plate 4 of coaming plate 1 upper end and be arranged between the bilayer of described double-layer rubber pad 3 from bottom to top and constituting; Described coaming plate 1 down plays the pad effect, and described double-layer rubber pad 3 and foam pad 2 seal, described adapter plate 4 fixing, squeezing actions; The beneficial effect that the utlity model has excellent sealing and guidance quality obtains by following improvement: some around described guide pipe 6 circumference uniform distributions on described adapter plate 4 to attaching parts 5, at each attaching parts 5 is installed scroll wheel 7 by rolling shaft 8 respectively near the front end of described guide pipe 6.Aforesaid guide pipe 6 can be various gauge pipes.
In order to adapt to the gauge pipe of various diameter ranges in actual applications, around quantity is set can between 3～8 pairs, selects arbitrarily of the attaching parts 5 of described guide pipe 6 circumference uniform distributions, described rolling shaft 8 and be installed in quantity is set also can be arranged between 3～8 of scroll wheel 7 on the described attaching parts 5 by described rolling shaft 8.In the present embodiment, described attaching parts 5 is 6 pairs, and described rolling shaft 8 and the scroll wheel 7 that is installed on the described attaching parts 5 by rolling shaft 8 are 6.
The utility model is used for the roller sealing arrangement of metal roof, and is rational in infrastructure, and guiding is reliable, can keep stable vertical uplift and the decline in floating top when guaranteeing excellent sealing, possesses practicality.
Below schematically the utility model and embodiment thereof are described, this description does not have restricted, and shown in the accompanying drawing also is one of embodiment of the present utility model.If those of ordinary skill in the art is enlightened by it, under the situation that does not break away from the utility model creation aim,, all should belong to protection domain of the present utility model without creationary structure similar and the embodiment of designing to this technical scheme.
