Air tightness testing device for air pipe centralized protection area

Abstract

The invention discloses an air tightness inspection device for an air pipe in a centralized protection area, and belongs to the technical field of ship inspection. The device comprises a plugging unit, an air source assembly, a vacuumizing assembly and a detection assembly; the plugging unit is arranged in the channel of an air pipe and can plug the air pipe to obtain an air pipe to be tested; theair source assembly is used for inflating the air pipe to be tested; the vacuumizing assembly is used for vacuumizing the air pipe to be detected; the detection assembly is communicated with the airpipe to be tested and used for detecting the pressure of the air pipe to be tested. According to the air tightness detection device for the air pipe in the centralized protection area, the air pipe issubjected to segmented detection, so that a leakage point is conveniently and quickly found, and the leakage detection efficiency is improved; the detection assembly can carry out positive pressure or negative pressure maintaining detection on the air pipe to be tested, so that detection indexes better accord with actual working conditions; the inspection device can carry out positive pressure ornegative pressure maintaining inspection on the air pipe firstly, when inspection indexes are qualified, inflation leakage detection does not need to be carried out on installation seams one by one,therefore, construction inspection workload and the leakage detection difficulty are reduced, and the inspection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of ship inspection, in particular to an air tightness inspection device for an air duct in a centralized defense area. Background technique [0002] The main function of the centralized defense area is to isolate the centralized defense area from the outside by taking protective measures and relying on the nuclear, biological and chemical filtration system to ventilate from the outside to prevent nuclear, biological and chemical substances such as toxic gases, chemical organisms, and radioactive suspended particles from entering with the air. Avoid harm in the biochemical environment, ensure the personal safety of the crew in the defense area, protect the hull and equipment from nuclear, biological and chemical substances, and maintain the safety of ship equipment and smooth communication. [0003] The air-tight air duct of the air-tight air-tight air duct of the special ship is an important part of the air-...

[0003] The air-tight air duct of the air-tight air-tight air duct of the special ship is an important part of the air-tight perimeter of the air-tight air-tight area of ​​the special ship. The outer end of the airtight duct is non-airtight facilities such as ventilation louvers, gooseneck ventilators and fungus-shaped ventilators. Inflating or negative pressure holding tests need to hermetically seal these facilit
