Preparation process of sealing ring with embedded rib ring

Abstract

The invention discloses a preparation process of a sealing ring with an embedded rib ring, and belongs to the field of sealing rings. According to the preparation process of the sealing ring with the embedded rib ring, the preprocessed embedded rib ring is embedded in the center of the sealing ring, the hardness difference between the embedded rib ring and the sealing ring is small, on one hand, the bearing performance of the sealing ring during longitudinal stress is remarkably improved, the pressure resistance of the sealing ring is improved remarkably, the deadline of cracking due to the fact that the sealing ring is in long-term stress is prolonged effectively, the service life of the sealing ring is improved, and the sealing performance is better; on the other hand, when cracks are generated due to long-term stress, glue solution generates extrusion force on a sealing liquid drum ring under the action of pressure, so that the sealing liquid drum ring seeps outwards, gradually overflows to the contact surface of two half rings along through holes and extends gradually, and the effect that an inner crack is repaired is achieved. Meanwhile, after cracking, moisture enters the sealing liquid drum ring from the outside, so that a powder wrapping ball is slightly melted gradually, and under the action of paper pulp, the internal color of the powder wrapping ball is bloomed and seeps outwards, so that a certain reminding effect is achieved.

Description

technical field [0001] The invention relates to the field of sealing rings, more specifically, to a preparation process of a sealing ring embedded with a rib ring. Background technique [0002] The sealing ring has the following advantages: [0003] 1. The sealing ring should have good sealing performance within the working pressure and a certain temperature range, and can automatically improve the sealing performance as the pressure increases. [0004] 2. The friction force between the sealing ring device and the moving parts should be small, and the friction coefficient should be stable. [0005] 3. The sealing ring has strong corrosion resistance, is not easy to age, has a long working life, good wear resistance, and can automatically compensate to a certain extent after wear. [0006] 4. The structure is simple, easy to use and maintain, so that the sealing ring has a longer life. [0007] When the sealing ring is in use, generally the two end faces are uniformly subj...

AI Technical Summary

Problems solved by technology

[0007] When the sealing ring is in use, generally the two end faces are uniformly subjected to a large extrusion force and sealed by extrusion, but under long-term stress, it is prone to fatigue, resulting in internal cracking, low strength, and poor sealing effect. In the technology, the effect of enhancing its strength is generally achieved by embedding a rigid structure. For example, the patent No. CN201821228902.0 discloses "A Sealing Ring for Petroleum Machinery". However, in this way, although the sealing ring bears However, there is a large difference in hardness at the contact between the embedded object and itself, resulting in a high probability of cracking at the contact between the embedded object and itself. Its cracking situation rarely has a reminder function, and it is difficult to meet people's needs
