A hatch cover pressure adjustable sealing device

Abstract

The invention discloses a hatch cover pressure-adjustable sealing device, which comprises a cabin coaming, a cover plate is hingedly arranged on one side of the upper end of the cabin coaming, and a handwheel pressing mechanism is provided in the middle of the cover plate. The bottom edge of the cover plate is provided with a vertically downward annular groove, the inside of the annular groove is provided with an annular sealing rubber, and the cover plate is provided with a pressure regulating mechanism. The invention conveniently adjusts the pressing strength of the cover plate, which can not only ensure the sealing effect between the hatch and the cover plate, but also prevent the cover plate from being deformed and damaged when the pressing force is high, and the setting of the pointer and the pressure scale is convenient for people to see To better understand the compression force of the cover plate, the setting of the card groove, sealing sub-plate, annular sealing air bag and annular sealing block can make the sealing effect of the cover plate better, and the use of multiple sealing sub-plates and cabin coamings and annular sealing rubber Multiple sealing layers are formed between them.

Description

technical field [0001] The invention relates to the technical field of hatch cover sealing, in particular to a hatch cover pressure-adjustable sealing device. Background technique [0002] The cabin is the various spaces below the nail plate, including the bow, stern, cargo, machinery and boiler rooms, etc. The hatch refers to the door or lattice cover that can enter the cabin vertically, that is, the opening on the deck of the ship for loading and unloading of goods, machinery or personnel. The hatch is generally equipped with a hatch cover, which is a device for closing the hatch on the ship. [0003] The traditional hatch cover sealing device only uses the sealing rubber and the coaming plate to squeeze each other to achieve a sealing effect, and the cover plate is moved up and down through the rotation of the handwheel to realize opening and closing. Sealing, and the pressing force of the cover plate is not easy to control. When the pressing force of the cover plate is...

AI Technical Summary

Problems solved by technology

[0003] The traditional hatch cover sealing device only uses the sealing rubber and the coaming to squeeze each other to achieve the sealing effect, and the cover is moved up and down by the rotation of the hand wheel to realize the opening and closing. The sealing effect of this device is not ideal, and a lot of pressure is required to Sealing, and the pressing force of the cover plate is not easy to control. When the pressing force of the cover plate is too high, it is easy to deform the cover plate and shorten the service life. When the pressing force of the cover plate is small, the sealing effect of the cover plate is insufficient and cannot be well To achieve the effect of sealing the hatch
