Abstract

The invention relates to a hatch cover with a ceramic layer and belongs to the technical field of deck machinery. The hatch cover with the ceramic layer comprises a cover plate, a coaming and a plurality of locking devices, wherein each locking device is used for tightly closing the hatch cover, a stop ring is fixedly arranged on a bottom surface of the cover plate and form a framework structure together with the cover plate by welding one or more reinforcing ribs, a sealing ring is arranged between the stop ring and a folding edge of the cover plate, the ceramic layer is arranged between thecover plate and the sealing ring, and the ceramic layer bulges towards the sealing ring in a circular arc shape. The ceramic layer slightly bulging towards the sealing ring is arranged between the cover plate and the sealing ring, so that two sides of the sealing ring slightly warp up when deformed under stress to fill sunken parts of two sides of the circular arc bulge, the sealing effect is better, and the ceramic layer can have a protection function on the cover plate to prevent the cover plate from being corroded when the sealing ring fails.

Description

technical field [0001] The invention relates to a hatch cover with a ceramic layer, 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 ceramic layer in view of the deficiencies in the prior art. [0004] The technical solution proposed by the present invention in order to solve the above technical problems is: a hatch cover with a ceramic layer, including a cover plate, a coaming plate and a plurality of locking devices, the locking devices are used to tightly close the hat...
