Example Embodiment
[0021] The present invention will be further described in detail below through specific embodiments:
[0022] See figure 1 , Which is a schematic structural view of a preferred embodiment of the involute type fingertip sealing device of the present invention. The involute type fingertip sealing device is composed of a front baffle 1, a back baffle 2, and six layers of fingertips 3 arranged between the two, and the front baffle 1, the back baffle 2 and the fingertips The tip piece 3 is connected by rivet riveting or welding. Wherein, the front baffle 1 is a ring-shaped plate-shaped structure, whose main function is to support and protect the fingertip sheet 3. This structure is similar to the front liner ring of the hydrostatic fingertip sealing structure, but has a front The function of the backing ring and the front spacer ring. The rear baffle 2 is also a ring-shaped plate structure, whose main function is to support and protect the fingertip sheet 3. This structure is simila...
