A60-grade watertight airtight double-opening fireproof door

Abstract

The invention relates to an A60-grade watertight airtight double-opening fireproof door, and particularly relates to the A60-grade watertight airtight double-opening fireproof door which is used for adeck with A-grade segmentation requirement; the A60-grade watertight airtight double-opening fireproof door meets the requirements of fire resistance grade A60 and airtight test pressure requirementof 0.02MPa, and belongs to the technical field of ship air-tight doors. The A60-grade watertight airtight double-opening fireproof door comprises a door frame and door leaves, wherein the left side and the right side in the door frame are symmetrically provided with two door leaves, the two door leaves are hinged on the left side and the right side of the door frame through a plurality of door hinges, and the door frame can be completely sealed when the two door leaves are closed; the left side and the right side of the door frame are internally provided with a first sealing groove and a second sealing groove, wherein a first fireproof expansion sealing rubber strip is arranged in the first sealing groove, a second fireproof expansion sealing rubber strip is arranged in the second sealinggroove; the first fireproof expansion sealing rubber strip is in sealing contact with the hinge part of the door leaves connecting door, and the second fireproof expansion sealing rubber strip is in sealing contact with the inner side part of the door leaves. The A60-grade watertight airtight double-opening fireproof door has the advantages of large lighting size, sound insulation and heat insulation, thereby improving water tightness and air tightness; the A60-grade watertight airtight double-opening fireproof door has the advantages of safety, reliability, and convenient and fast in operation and maintenance.

Description

technical field [0001] The present invention relates to an A60 grade watertight and airtight double-leaf fire door, specifically an A60 grade watertight and airtight door for decks with A grade division requirements, meeting the fire resistance grade of A60 and the airtightness test pressure requirement of 0.02MPa. The utility model relates to a double-leaf fireproof door, which belongs to the technical field of airtight doors for ships. Background technique [0002] With the development of the ship industry, customers have higher and higher requirements for ship outfitting equipment. In the prior art, the A60 double-leaf steel weathertight fire door is mainly composed of a door frame, a door leaf, a hinge device, a pressing device and other connections. This kind of A60 double-leaf steel weathertight fireproof door leaf is connected to the connecting rod with multiple rolling buckles, and the handle is used to press and loosen in linkage, and there is no room for adjustmen...

AI Technical Summary

Problems solved by technology

This kind of A60 double-leaf steel weathertight fireproof door leaf is connected to the connecting rod with multiple rolling buckles, and the handle is used to press and loosen in linkage, and there is no room for adjustment; both the door frame and the inside of the door leaf must be milled and buckled. , the processing is difficult; the force is very large when closing and pressing, and it is difficult to open and close and maintain

Therefore, the existing A60 double-leaf steel weathertight fire door is not easy to maintain, it is too heavy, it takes a lot of effort to close and press, there is no square window, and there is no airtight performance, which can no longer meet the needs of customers in the new situation.
