Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to an ozone corrosion resistant sealing ring. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of machinery and equipment. The best storage room temperature for seals is below 30°C to avoid high temperature aging of seals. Sealing rings are the most common seals, and the selection of sealing ring materials is of great significance to their sealing performance and service life. The performance of the material directly affects the performance of the sealing ring.

[0003] The existing sealing rings have poor corrosion resistance and wear resistance. Since the function of the sealing ring is to prevent liquid leakage, the sealing ring is very easy to come into contact with the liquid. Long-term contact with the liquid can easily cause the sealing ring to be corroded, thereby damaging the sealing ring. The sealing ring is generally installed in a sealing groove, and it is very easy to generate friction with the installation object during installation and use, causing damage to the sealing ring and affecting its service life.

[0004] For this purpose, a sealing ring resistant to ozone corrosion is specially proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an ozone corrosion resistant sealing ring to solve the problem in the above background technology that the existing sealing rings have poor corrosion resistance and wear resistance, which causes damage to the sealing ring and affects the service life. To achieve the above purpose, the utility model provides the following technical solutions: an ozone corrosion resistant sealing ring, comprising a sealing ring main body, a sealing ring reinforcement rib is arranged inside the sealing ring main body, a pressure-resistant layer is arranged on both sides of the sealing ring reinforcement rib, a wear-resistant layer is arranged on one side of the pressure-resistant layer, and an anti-corrosion coating is arranged on the outer side of the wear-resistant layer.

[0006] Preferably, the cross-sectional view of the sealing ring body is in the shape of a Chinese character "concave".

[0007] Preferably, the material of the anti-corrosion coating is Venus OCN-4000 anti-ozone coating, and the anti-corrosion coating is evenly coated on the outside of the wear-resistant layer.

[0008] Preferably, the wear-resistant layer is made of nitrile rubber, and the sealing ring reinforcement ribs are made of high-strength chemical fiber.

[0009] Preferably, a mounting groove is provided on one side of the sealing ring body, and the bottom end of the mounting groove extends into the interior of the sealing ring body.

[0010] Preferably, the material of the compression-resistant layer is bamboo fiber, and the compression-resistant layer is evenly distributed on both sides of the reinforcing ribs.

[0011] Compared with the prior art, the utility model provides an ozone corrosion resistant sealing ring having the following features:

[0012] Beneficial effects:

[0013] By providing a wear-resistant layer, a sealing ring body, a sealing ring reinforcement rib and an anti-corrosion coating, since the outer side of the wear-resistant layer is evenly coated with the anti-corrosion coating, the outer side of the sealing ring is evenly coated with the anti-corrosion coating, which can ensure the normal use of the sealing ring in an ozone environment, and improve the ability of the sealing ring to resist ozone corrosion, thereby greatly improving the service life of the sealing ring. Since the sealing ring reinforcement rib is installed inside the sealing ring body, the sealing ring reinforcement rib can enhance the overall tensile strength of the sealing ring body, thereby ensuring that the sealing ring will not be broken or damaged during the installation process.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1: It comprises a sealing ring body 1, a sealing ring reinforcement rib 2 is arranged inside the sealing ring body 1, pressure-resistant layers 3 are arranged on both sides of the sealing ring reinforcement rib 2, a wear-resistant layer 5 is arranged on one side of the pressure-resistant layer 3, an anti-corrosion coating 6 is arranged on the outer side of the wear-resistant layer 5, the material of the anti-corrosion coating 6 is Venus OCN-4000 anti-ozone coating, and the anti-corrosion coating 6 is evenly coated on the outer side of the wear-resistant layer 5.

[0021] Specifically, Figure 1 , Figure 2 and Figure 4As shown in the figure, since the outer side of the wear-resistant layer 5 is evenly coated with an anti-corrosion coating 6, and the material of the anti-corrosion coating 6 is Venus OCN-4000 anti-ozone paint, this paint has excellent weather resistance and chemical corrosion resistance, and can protect equipment and components in harsh environments such as ozone, pollutants, and ultraviolet rays. Evenly coating the outer side of the sealing ring with the anti-corrosion coating 6 can ensure the normal use of the sealing ring in an ozone environment, and improve the ozone corrosion resistance of the sealing ring, greatly improving the service life of the sealing ring. Since the sealing ring reinforcement 2 is installed inside the sealing ring body 1, the overall tensile strength of the sealing ring body 1 can be enhanced through the sealing ring reinforcement 2, thereby ensuring that the sealing ring will not break or be damaged during the installation process.

[0022] Embodiment 2: The cross-section of the sealing ring body 1 is in a "concave" shape. The material of the wear-resistant layer 5 is nitrile rubber, the material of the sealing ring reinforcement 2 is selected as high-strength chemical fiber. One side of the sealing ring body 1 is provided with an installation groove 4, and the bottom end of the installation groove 4 extends into the inside of the sealing ring body 1. The material of the compression-resistant layer 3 is bamboo fiber, and the compression-resistant layer 3 evenly covers both sides of the reinforcement 2.

[0023] Specifically, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, since an installation groove 4 is provided on one side of the sealing ring body 1, the installation of the sealing ring can be made more convenient through the installation groove 4, and the sealing performance is stronger. Since the material of the wear-resistant layer 5 is nitrile rubber, nitrile rubber has good wear resistance, oil resistance, acid and alkali resistance, and weather resistance, and has good mechanical properties within a wide temperature range. Since the material of the sealing ring reinforcement 2 is high-strength chemical fiber, the overall service strength of the sealing ring body 1 can be enhanced through the sealing ring reinforcement 2, and the service life of the sealing ring body 1 can be improved.

[0024] Working principle: During installation, since an installation groove 4 is provided on one side of the sealing ring body 1, the installation groove 4 can ensure that the sealing ring is more convenient to install and has a stronger sealing performance. Since the wear-resistant layer 5 is made of nitrile rubber, nitrile rubber has good wear resistance. Since the outer side of the wear-resistant layer 5 is evenly coated with an anti-corrosion coating 6, and the material of the anti-corrosion coating 6 is Venus OCN-4000 anti-ozone coating, the coating has excellent weather resistance and chemical corrosion resistance, and can protect equipment and components in harsh environments such as ozone, pollutants, and ultraviolet rays. Evenly coating the outer side of the sealing ring with the anti-corrosion coating 6 can ensure that the sealing ring is used normally in an ozone environment, and improve the sealing ring's ability to resist ozone corrosion, greatly improving the service life of the sealing ring. Since the sealing ring main body 1 is installed with a sealing ring reinforcement rib 2, the sealing ring reinforcement rib 2 can enhance the overall tensile strength of the sealing ring main body 1, thereby ensuring that the sealing ring will not be broken or damaged during installation.
