Abstract
The present invention relates to a kind of hatch board with modified rubber sealing ring, belong to deck machinery technical field.The hatch board with modified rubber sealing ring, including cover plate, coaming plate and multiple locking devices, the locking device is used to close hatch board, described cover plate has been fixedly mounted on the bottom surface with back-up ring, the back-up ring collectively forms frame structure by more than one reinforcement of solid welding and cover plate, sealing ring is provided between back-up ring and the flanging of cover plate, is provided with ceramic layer between cover plate and sealing ring, the ceramic layer to sealing ring projection be in circular arc.The present invention between cover plate and sealing ring by setting one to the pico- raised ceramic layer of sealing ring; so that sealing ring meeting both sides in stress and deformation can tilt slightly; it is filled into the raised both sides recess of circular arc; so that sealing effectiveness is more preferable; simultaneously when sealing ring fails; changing ceramic layer can also play a protective role to cover plate, prevent cover plate to be corroded.
Description
Technical field
The present invention relates to a kind of hatch board with modified rubber sealing ring, belong to deck machinery technical field.
Background technology
At present, International Association of Classification Societies (IACS) code requirement ship manufactured after 2004, in its ship
The small-sized hatch board of exposed section in the range of first 0.25 captain, it is the hatch board for needing with locking device to strengthen using cover plate.It is existing
Steel hatch cover standard can not meet its requirement.
The content of the invention
The technical problem to be solved in the present invention is, in view of the shortcomings of the prior art, proposing a kind of with modified rubber sealing ring
Hatch board.
The technical scheme that in order to solve the above-mentioned technical problem proposes of the present invention is:A kind of cabin with modified rubber sealing ring
Lid, including cover plate, coaming plate and multiple locking devices, the locking device are used to close hatch board, the bottom of described cover plate
Back-up ring is installed with face, the back-up ring collectively forms frame structure, back-up ring and cover plate by more than one reinforcement of solid welding and cover plate
Flanging between be provided with sealing ring, ceramic layer is provided between cover plate and sealing ring, the ceramic layer is convex to the sealing ring
It is in circular arc to rise;The composition of sealing ring includes by weight percentage, natural rubber 70-80%, double jealous woman pulullan polysaccharide 0.1-
0.2%, silk gum 0.1-0.3%, machine bentonite 2-5%, polyvinyl chloride 30-40%.
The improvement of above-mentioned technical proposal is:The radian of the raised circular arc formed of the ceramic layer is π/18 --- π/12.
It is of the invention to be using the beneficial effect of above-mentioned technical proposal:The present invention between cover plate and sealing ring by setting one
The individual ceramic layer to the pico- projection of sealing ring so that sealing ring meeting both sides in stress and deformation can tilt slightly, be filled into circular arc
Raised both sides recess so that sealing effectiveness is more preferable, while when sealing ring fails, changing ceramic layer can also play to cover plate
Protective effect, cover plate is prevented to be corroded.
Brief description of the drawings
The invention will be further described below in conjunction with the accompanying drawings.
Fig. 1 is a kind of structural representation of hatch board with modified rubber sealing ring of the embodiment of the present invention.
Fig. 2 is the X close-up schematic views of figure.
Embodiment
Embodiment
A kind of hatch board with modified rubber sealing ring of the present embodiment, including cover plate 1, coaming plate and multiple locking dresses
Put, the locking device is used to close hatch board, and described cover plate 1 has been fixedly mounted on the bottom surface with back-up ring 2, and the back-up ring 2 passes through weldering
Gu more than one reinforcement collectively forms frame structure with cover plate 1, sealing ring 4 is provided between back-up ring 2 and the flanging of cover plate 1,
Be provided with ceramic layer 3 between cover plate 1 and sealing ring 4, the ceramic layer 3 to the projection of sealing ring 4 be in circular arc;The ceramics
Layer includes refractory ceramic fibre or biosoluble inorganic fibers;Viscosity modifier;Colloidal inorganic oxide;Inorganic bond;
Inorganic particles;With glass fibre, leaching silicon dioxide fibre, alumina fiber, mullite fiber, Almasilate fiber, S-
At least one of 2 fibers, basalt fibre or thin diameter alumina silicate fibre.
The radian of the raised circular arc formed of ceramic layer 3 is π/18 --- π/12.
The present invention is not limited to above-described embodiment.All technical schemes formed using equivalent substitution, all fall within application claims
Protection domain.
