[0038] Example 2

[0039] This embodiment is based on the specially designed inspection port in Embodiment 1, and elaborates on its specific use process.

[0040] During the application of the inspection hidden door, if the internal pipeline needs to be inspected, the movable door 2 needs to be pushed inward, and the movable door 2 rotates inward with the first rotating axis 3 as the center. The movable door 2 pushes the first connecting rod 601 inward through the second connecting shaft assembly 9, and the first connecting rod 601 pushes the second connecting rod 602 to move through the second rotating axis 603, and overcomes the elastic force of the compression spring 503, so that the second connecting rod 602 drives the guide block 504 to move away from the inspection port 1, thereby opening the movable door 2.

[0041] While the movable door 2 is opened, the rotating disk 404 is rotated to adjust the direction of the positioning rod 407, and the end of the positioning rod 407 is inserted into the positioning groove 7 through the first connecting shaft assembly 406, and the pushing of the movable door 2 is stopped. The guide block 504 is pushed outward by the elastic force of the compression spring 503, and the movable door 2 is pushed through the guide block 504 and the connecting rod assembly 6 to rotate the movable door 2 outward until the positioning rod 407 is stuck in the positioning groove 7, and an extrusion force is applied to the positioning rod 407 through the movable door 2 to prevent the positioning rod 407 from being separated from the positioning groove 7, and the movable door 2 is limited and fixed by the cooperation of the positioning groove 7 and the positioning rod 407, so that the movable door 2 remains in an open state, which is convenient for maintenance personnel to inspect the pipeline valve.

[0042] After the maintenance is completed, push the movable door 2 to rotate inward again, overcoming the elastic force of the compression spring 503. The positioning rod 407 loses the extrusion force, and the positioning rod 407 is taken out from the positioning groove 7. Release the movable door 2, and use the elastic force of the compression spring 503 to push the guide block 504 outward. Through the cooperation of the guide block 504 and the connecting rod assembly 6, push the movable door 2 outward until the movable door 2 is completely closed.

[0043] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
