Abstract

The invention belongs to the technical field of double-layer casing hole plugging design, and particularly relates to a hole plugging structure. The hole plugging structure comprises a mounting plate,a first spring and a plug, wherein one end of the first spring is connected to the inner wall of a mounting cavity; and the plug is connected to the other end of the first spring. In addition, the invention relates to a double-layer casing hole plugging structure, and the double-layer casing hole plugging structure comprises the hole plugging structure.

Description

technical field [0001] The application belongs to the technical field of hole-plugging design of double-layer casings, and in particular relates to a hole-plugging structure and the hole-blocking structure of double-layer casings. Background technique [0002] In order to facilitate the inspection and maintenance of the compressor parts in the engine, a borescope hole is usually set on the casing. Carry out the borescope inspection. After the inspection is completed, take out the borescope and plug the hole of the borescope on the casing with a plug to ensure engine performance. [0003] The current plug can well block the hole of the borescope on the single-layer casing to effectively ensure the performance of the engine. Due to the multi-layer casing structure, the existing plugs cannot effectively block the probe holes on the upper holes, and cannot guarantee engine performance. [0004] In view of the existence of above-mentioned technical defect, propose this applicat...
