Detailed Description

The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the relevant invention and not restrictive of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

As shown in fig. 1, 2 and 3, the sealing disc spring device comprises a disc spring leaf a1 and a disc spring leaf b2, the disc spring leaf a1 and the disc spring leaf b2 are connected with each other to form a sealing disc spring with a cavity, the bottom of the disc spring leaf a1 is provided with a plurality of buffer pieces a3 around the circumference, the buffer pieces a3 are shaped like isosceles triangles, the bottom of the buffer pieces a3 is fixed at the bottom of the disc spring leaf a1, the upper end of the buffer pieces a3 is abutted against the top of the disc spring leaf b2, the top of the disc spring leaf b2 is provided with a plurality of buffer pieces b4 around the circumference, the buffer pieces b4 is shaped like isosceles triangles, the bottom of the buffer pieces b4 is fixed at the top of the disc spring leaf b2, the upper end of the buffer pieces b4 is abutted against the bottom of the disc spring leaf a1, the left side of the buffer pieces a3 is abutted against the right side of the buffer pieces b 5, the right side of the buffer pieces a 4 is abutted against the left side of the buffer pieces b 573, the buffer piece a3 and the buffer piece b4 are positioned in a cavity between the disc spring piece a1 and the disc spring piece b 2.

As shown in fig. 3, a plurality of the buffer pieces a3 are uniformly arranged at the bottom of the disc spring piece a 1. The buffer sheet b4 and the buffer sheet a3 are the same in shape and size.
