Embodiment Construction

[0013] like figure 2 and image 3 As shown, the hinged pressure-resistant watertight door of the present invention includes a door frame 1 and a door panel 2, and one side of the door frame 1 and the door panel 2 is hinged together by means of a hinge. An inner convex edge 3 is processed around the outer edge of the door frame 1 , and the inner convex edge is formed by welding metal plates, and its thickness is greater than that of the door frame 1 . A frame is welded around the door panel 2 , and the perimeter of the frame protrudes outside the inside of the door panel 2 , so that an inward protrusion 5 is formed around the door panel 2 . The thickness of the inward protrusion 5 is equal to the thickness of the inner flange 3 of the door frame 1 .

[0014] A circumferential groove is processed on the outer surface of the inner flange 3 of the door frame 1, and a sealing strip 4 is embedded in the circumferential groove, and the sealing strip 4 protrudes outside the circumf...

Abstract

The invention discloses a hinged pressure-proof water tight door, in particular to a hinged pressure-proof water tight door with pressure-proof performance, which is applicable to cabin doors of various ships. The water tight door comprises a door frame and a door plate, wherein the edges of the door frame and the door plate are hinged together by hinges. A seal strip is arranged between the periphery of the door plate and the door frame. The water tight door is characterized in that the periphery of the outer edge of the door frame is provided with an inner convex edge, and the thickness of the inner convex edge is bigger than the thickness of the door frame. The water tight door has the advantages of favorable pressure-proof performance and low production cost.

Description

technical field [0001] The invention relates to a hatch on a ship. Specifically, it is a hinged pressure-resistant watertight door with pressure resistance, which is suitable for the hatch doors of various ships. Background technique [0002] It is well known in the shipbuilding industry that in order to ensure the watertight performance of ships, most of the cabin doors of ships use hinged watertight doors. like figure 1 As shown, a traditional hinged watertight door includes a door frame 1 and a door panel 4, and one side of the door frame 1 and the door panel 4 is hinged together by means of a hinge. Wherein, an outer flange 2 is processed around the inner edge of the door frame 1 , the outer flange is perpendicular to the outer surface of the door frame 1 , and the thickness of the outer flange 2 is equal to the thickness of the door frame 1 . The inner surface around the door panel 4 is provided with a groove, and a sealing strip 3 is embedded in the groove. When th...
