[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-4 This utility model provides a technical solution: an industrial high-airtightness rubber sealing ring, including a sealing body 1, a sealing lip 2 fixedly connected to the outer side of the sealing body 1, and a mating ring 3, with a reinforcing part 4 fixedly connected to the outer side of the mating ring 3; the reinforcing part 4 includes an outer ring 41, an arc-shaped ring 42 fixedly connected to the inner side of the outer ring 41, an inner ring 43 fixedly connected to the side of the arc-shaped ring 42 away from the outer ring 41, a reinforcing ring 44 fixedly connected to the inner side of the inner ring 43, a support ring 47 fixedly connected to the inner side of the arc-shaped ring 42, a buffer ring 45 fixedly connected to the inner side of the outer ring 41, and a protective ring 46 fixedly connected to the inner side of the buffer ring 45. When this rubber sealing ring is installed in the sealing part of industrial equipment, the sealing body... Body 1, relying on its own rubber elasticity, fits tightly against the sealing part, initially forming a sealing barrier to prevent gas leakage. The sealing lip 2 can fit tightly against the surface of the sealing part. Even if there are minor unevenness or irregularities on the surface, it can fill the gaps through its own elastic deformation, preventing gas from leaking from the outside of the sealing body 1. The reinforcing part 4 plays a key supporting and strengthening role in the entire sealing ring, preventing the sealing body 1 from being excessively deformed and resulting in poor sealing performance. The outer ring 41 provides a stable external frame for the reinforcing part 4, ensuring a tight connection between the reinforcing part 4, the sealing body 1, and the mating ring 3. The arc-shaped ring 42 not only increases the structural strength of the reinforcing part 4 but also disperses the pressure from the outside to a certain extent. When the sealing body 1 is under pressure, the arc-shaped ring 42 can evenly transmit the pressure to the entire reinforcing part 4, avoiding excessive local pressure that could cause deformation of the sealing body 1.

[0024] The outer side of the reinforcing part 4 engages with the inner side of the sealing body 1, and the outer side of the mating ring 3 contacts the outer side of the sealing body 1. There are four sealing lips 2, arranged in a ring along the outer side of the sealing body 1. The reinforcing part 4 can be removed from the sealing body 1 through the mating ring 3. The reinforcing part 4 can be easily separated from the sealing body 1 by operating the mating ring 3. After removing the reinforcing part 4, a new sealing body 1 can be replaced, and then the reinforcing part 4 can be reinstalled inside the new sealing body 1, restoring the sealing ring to its good sealing performance. This replaceable design greatly improves the service life and maintenance efficiency of the sealing ring, and reduces operating costs.

[0025] The outer side of the outer ring 41 engages with the inner side of the sealing body 1, and the outer side of the outer ring 41 is fixedly connected to the outer side of the mating ring 3. The outer side of the arc-shaped ring 42 is arranged in a ring along the inner side of the outer ring 41. The buffer ring 45 is located between the arc-shaped ring 42 and the outer ring 41. Both the buffer ring 45 and the support ring 47 are arranged in a ring along the inner side of the outer ring 41. The support ring 47 provides additional support for the arc-shaped ring 42. When the sealing body 1 is subjected to impact or pressure changes, the buffer ring 45 can absorb some energy and reduce the impact on the sealing body 1. The protective ring 46 protects the buffer ring 45 and prevents it from being deformed by excessive compression.

[0026] Working principle:

[0027] When the rubber sealing ring is installed on the sealing part of industrial equipment, the sealing body 1 relies on its own rubber elasticity to fit tightly with the sealing part, initially forming a sealing barrier to prevent gas leakage. The sealing lip 2 can fit tightly with the surface of the sealing part. Even if there are slight unevenness or irregularities on the surface, it can fill the gap through its own elastic deformation to prevent gas from leaking from the outside of the sealing body 1.

[0028] The reinforcing part 4 plays a crucial supporting and strengthening role in the entire sealing ring, preventing excessive deformation of the sealing body 1 that could lead to poor sealing performance. The outer ring 41 provides a stable external frame for the reinforcing part 4, ensuring a tight connection between the reinforcing part 4, the sealing body 1, and the mating ring 3. The arc-shaped ring 42 not only increases the structural strength of the reinforcing part 4 but also disperses external pressure to a certain extent. When the sealing body 1 is subjected to pressure, the arc-shaped ring 42 can evenly transmit the pressure to the entire reinforcing part 4, preventing excessive local pressure from causing deformation of the sealing body 1.

[0029] The reinforcing ring 44 within the inner ring 43 further enhances the internal structural strength of the reinforcing part 4, enabling it to better resist external pressure and protect the sealing body 1 from excessive deformation. Simultaneously, the support ring 47 provides additional support for the arc-shaped ring 42. When the sealing body 1 is subjected to impact or pressure changes, the buffer ring 45 can absorb some energy, reducing the impact on the sealing body 1. The protective ring 46 protects the buffer ring 45, preventing it from being excessively compressed and deformed.

[0030] In practical use, if the sealing body 1 wears or is damaged due to long-term use, the reinforcing part 4 can be removed from the sealing body 1 through the mating ring 3. The reinforcing part 4 can be easily separated from the sealing body 1 by operating the mating ring 3. After removing the reinforcing part 4, a new sealing body 1 can be replaced, and then the reinforcing part 4 can be reinstalled inside the new sealing body 1, restoring the sealing ring to good sealing performance. This replaceable design greatly improves the service life and maintenance efficiency of the sealing ring, and reduces operating costs.
