Problems solved by technology

[0002] The aero-engine is the core system of the aircraft. It is called the "Pearl in the Crown" of the industry because of its many disciplines, wide technical fields, high technical difficulty, and long development cycle. In order to obtain reliable aero-engine products, it is necessary to A large amount of experimental research work has been carried out on the engine. How to ensure that the numerous test leads can be successfully drawn from the inside of the engine and effectively reduce the leakage of internal gas is an important research content for engine researchers. The current method is to target each According to the type and quantity of test lead wires, design corresponding sealing caps. The advantage of this method is that the sealing caps are specially tailored for the lead ports, and the sealing effect is better. However, the specifications of each sealing cap are different, and they are universal Very poor, at the same time a large number of sealing plugs greatly increase the cycle and cost of engine development

Embodiment 1

[0035] Such as Figure 1-10 As shown, a sealing plug for aero-engine test lead wires includes an adjusting piece 1, a base 2, a spring 3 and a cover plate 4;

[0036] The side of the base 2 is provided with a threaded hole a2-1 and a light hole a2-2;

[0037] The center of the base 2 is provided with a sliding groove 2-3, and the bottom is provided with an installation groove 2-4;

[0038] The outline shape of the main body of the cover plate 4 is the same as that of the base 2, and there are threaded holes b4-1 and light holes b4-2 at the same opening positions as the base 2;

[0039] Both the threaded hole a2-1, the threaded hole b4-1 and the light hole a2-2, the light hole b4-2 are through holes;

[0040] One end of the cover plate 4 is provided with an installation edge 4-4, and an unthreaded through hole a4-3 is provided on the installation edge 4-4;

[0041] The outline shape of the main body of the sealing gasket 10 is the same as that of the base 2, and a non-thread...

Embodiment approach 2

[0053] combined with Figure 1 ~ Figure 2 The specific implementation of the present invention is described. The sealing plug of the embodiment adopts the design concept of split body and modularization. The central diameter of the cover is not affected by the test lead connector, which not only has high convenience in installation and disassembly, but also can complete the connection between the connector and the test lead before the lead, which improves the accuracy of the test.

Embodiment approach 3

[0055] combined with Figure 8 ~ Figure 10 Describe the specific embodiment of the present invention, the spring 3 of the embodiment is a key structure in the design of the sealing plug, the natural length of the spring 3 should be connected with the adjustment piece 1 according to the spring 3 and after being installed on the base 2, the adjustment piece and the base 2 The length of the front end surface is flat or slightly protruding. The purpose of this design is to ensure that the spring 3 always has a part of the elastic potential energy so that the adjustment piece 1 can press the test lead 8, reduce the leakage of the airflow along the radial direction of the engine, and ensure The sealing plug has a better sealing effect.
