Embodiment

[0011] A hatch cover with a modified rubber sealing ring in this embodiment includes a cover plate 1, a coaming plate and a plurality of locking devices, the locking devices are used to tightly close the hatch cover, and the cover A retaining ring 2 is fixed on the bottom surface of the plate 1. The retaining ring 2 forms a frame structure together with the cover plate 1 by welding more than one reinforcing rib. A sealing ring 4 is arranged between the retaining ring 2 and the folded edge of the cover plate 1. A ceramic layer 3 is arranged between the cover plate 1 and the sealing ring 4, and the ceramic layer 3 protrudes toward the sealing ring 4 in an arc shape; the ceramic layer includes refractory ceramic fibers or biosoluble inorganic fibers; a viscosity modifier ; colloidal inorganic oxides; inorganic binders; inorganic particles; and, glass fibers, leached silica fibers, high alumina fibers, mullite fibers, magnesium aluminosilicate fibers, S-2 fibers, basalt fibers or ...

Abstract

The invention relates to a hatch cover provided with a modified rubber seal ring, and belongs to the technical field of deck machinery. The hatch cover provided with the modified rubber seal ring comprises a cover plate, a coaming and a plurality of locking devices, the locking devices are used for locking the hatch cover, a retaining ring is fixedly arranged on the bottom face of the cover plate,and the retaining ring with more than one reinforcing rib being fixedly welded and the cover plate jointly form a frame structure; and a seal ring is arranged between the retaining ring and the edgefold of the cover plate, a ceramic layer is arranged between the cover plate and the seal ring, and the ceramic layer protrudes towards the seal ring to be in a circular arc shape. According to the hatch cover provided with the modified rubber seal ring, the ceramic layer slightly protruding towards the seal ring is arranged between the cover plate and the seal ring so that the two sides of the seal ring can slightly upwarp when the seal ring deforms under stress, the concave positions on the two sides of the circular-arc protrusion are filled with the seal ring, therefore the sealing effect can be better, meanwhile when the seal ring loses efficacy, the modified ceramic layer can further achieve a protective effect on the cover plate, and the cover plate is prevented from being corroded.

Description

technical field [0001] The invention relates to a hatch cover with a modified rubber sealing ring, which belongs to the technical field of deck machinery. Background technique [0002] At present, the International Association of Classification Societies (IACS) regulations require that for ships manufactured after 2004, the small hatch covers exposed within the 0.25 length of the bow should be reinforced with cover plates and locking devices. . The existing steel hatch cover standards can no longer meet its requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a hatch cover with a modified rubber sealing ring in view of the deficiencies in the prior art. [0004] The technical solution proposed by the present invention in order to solve the above-mentioned technical problems is: a hatch cover with a modified rubber sealing ring, including a cover plate, a coaming plate and a plurality of locking devices...
