Abstract

The invention relates to the technical field of engineering protection, and discloses a protective sealing gate valve of a through-wall air pipe and a sealing method of the protective sealing gate valve. The protective sealing gate valve comprises a box, a sealing cover plate assembly and a driving assembly, wherein the sealing cover plate assembly is arranged in the box, and the driving assemblydrives the sealing cover plate assembly to be opened or closed; the box includes a connecting pipe body and an equipment box communicating with each other; openings of the two ends of the connecting pipe body are correspondingly hermetically connected with a through-wall pipe fitting and the air pipe, wherein the through-wall pipe fitting is pre-embedded in a wall; the equipment box is located atone side of the connecting pipe body; the sealing cover plate assembly includes a sealing gate and sliding pieces, wherein the sealing gate fits in with the orifice of the through-wall pipe fitting and the sliding pieces are located on the surface of the sealing gate; the sliding pieces are arranged in a high-position slidway or a low-position slideway at the two sides in a fit sliding manner; thesealing gate is connected with the driving assembly through a connecting rod; and the driving assembly includes a transmission assembly used for outputting power and a guide assembly used for adjusting a power direction. The protective sealing gate valve does not need to be installed and disassembled, is convenient to use, time-saving and labor-saving and has high airtightness.

Description

technical field [0001] The invention relates to the technical field of engineering protection, in particular to a protective and airtight gate valve for a through-wall air duct and a sealing method thereof. Background technique [0002] According to the relevant provisions of my country's "Civil Air Defense Law", the construction of subway projects must take into account the needs of civil air defense during wartime. The civil air defense system in the urban subway is an extremely important part of the urban civil air defense. The construction of the underground railway should take into account the needs of the civil air defense, and achieve the combination of peacetime and wartime and comprehensive utilization. [0003] When air ducts and other pipelines pass through the airtight partition wall or the empty wall between protective units, plate-type protective airtight sealing plates or protective airtight doors are usually used for immediate sealing. These two solutions hav...
