[0053] Where S is the contact width, σ max —Maximum contact stress

[0054] The compression rate W of the first rubber ring 71, the second rubber ring 81 or the third rubber ring 83 is usually expressed by the following empirical formula:

[0055]

[0056] Wherein D0 is the cross-sectional diameter of the first rubber ring 71 or the second rubber ring 81 or the third rubber ring 83 in a free state, and h is the distance between the bottom of the first mounting groove 72 or the second mounting groove 82 and the sealing surface (i.e., the cross-sectional height of the first rubber ring 71 or the second rubber ring 81 or the third rubber ring 83 after compression).

[0057] The first rubber ring 71 or the second rubber ring 81 or the third rubber ring 83 can have a longer service life when the compression rate does not exceed 15%-20% of the original cross section.

[0058] In summary, after relevant calculations and structural design, the flange 21 provides pressure to control the compression rate of the first rubber ring 71 or the second rubber ring 81 or the third rubber ring 83 to 17%, and at the same time, a small amount of silicone grease is applied to the first rubber ring 71 or the second rubber ring 81 or the third rubber ring 83 to compensate for the insufficient smoothness of the sealing surface of the first rubber ring 71 or the second rubber ring 81 or the third rubber ring 83 and to play a lubricating role.
