Description

Technical Field

[0001] This utility model relates to the field of graphite sealing ring technology, specifically a high-temperature resistant graphite sealing ring. Background Technology

[0002] Graphite self-sealing rings are molded from low-sulfur expanded graphite, with precise dimensions and a fixed density. They contain no external fillers or binders and possess all the properties of expanded graphite, capable of withstanding drastic temperature and pressure changes. They are ideal packings for water pumps, valves, and various static seals. However, most existing graphite sealing rings are integrally molded, resulting in high internal stress. Once worn or damaged, the entire ring needs to be replaced, leading to high costs. Therefore, a high-temperature resistant graphite sealing ring is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A high-temperature resistant graphite sealing ring includes a central body, an outer retaining ring on the side of the central body, an outer retaining groove on the outer retaining ring, an inner retaining groove on the inner side of the central body, a protective ring I sleeved on the central body, an inner retaining ring sleeved on the inner side of the central body, an inner retaining buckle on the inner retaining ring that fits into the inner retaining groove, a retaining ring installed on the central body, a second protective ring installed on the outer side of the retaining ring, and an outer retaining buckle installed on the side of the retaining ring, the outer retaining buckle being adapted to the outer retaining groove.

[0006] Preferably, the inner diameter of the central body is equal to the outer diameter of the inner retaining ring, and the inner retaining buckle is engaged in the inner retaining groove.

[0007] Preferably, the outer diameter of the outer retaining ring is equal to the inner diameter of the protective ring.

[0008] Preferably, the bottom of the locking ring abuts against the central body, and the outer locking buckle is engaged in the outer locking groove.

[0009] Preferably, the outer diameter of the second protective ring is equal to the outer diameter of the inner retaining ring, and the inner diameter of the second protective ring is equal to the inner diameter of the inner retaining buckle.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0011] In this invention, the original integrated graphite sealing ring is divided into three parts: a central body, a first protective ring, and a second protective ring. The central body is enclosed by the first and second protective rings, thus providing protection for the central body during use. As the first and second protective rings wear out over time, they can be replaced with new parts instead of the entire ring, reducing material waste and saving costs. Furthermore, even if damage occurs, the split design significantly weakens the force that could cause the damage, improving the reliability of the device. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a high-temperature resistant graphite sealing ring.

[0021] Example:

[0022] Combination Figure 1-5As shown, this utility model provides a high-temperature resistant graphite sealing ring, including a central body 101. An outer retaining ring 103 is provided on the side of the central body 101, and an outer locking groove 104 is formed on the outer retaining ring 103. An inner locking groove 102 is formed on the inner side of the central body 101. A protective ring 105 is sleeved on the central body 101. The outer diameter of the outer retaining ring 103 is equal to the inner diameter of the protective ring 105. An inner retaining ring 106 is sleeved on the inner side of the central body 101, and an inner retaining buckle 107 is provided on the inner retaining ring 106 to engage with the inner locking groove 102. The inner diameter of the central body 101 is equal to the inner diameter of the inner retaining ring 106. The outer diameter of the inner locking buckle 107 is engaged in the inner locking groove 102. A locking ring 108 is installed on the center body 101. A second protective ring 110 is installed on the outer side of the locking ring 108. An outer locking buckle 109 is installed on the side of the locking ring 108. The outer locking buckle 109 is adapted to the outer locking groove 104. The bottom of the locking ring 108 abuts against the center body 101. The outer locking buckle 109 is engaged in the outer locking groove 104. The outer diameter of the second protective ring 110 is equal to the outer diameter of the inner locking ring 106. The inner diameter of the second protective ring 110 is equal to the inner diameter of the inner locking buckle 107.

[0023] Specifically, the protective ring 105 supports the position of the central body 101, and the locking ring 108 fills the space above the central body 101. With the inner locking ring 106 and the protective ring 110, a smooth and round graphite sealing ring is obtained, which ensures the appearance of the device and improves its reliability. At the same time, the dimensions of each component are precisely matched, so the components can be firmly fixed together. Therefore, a slight inward supporting force can make the device stable to use, thus improving the practicality of the device.

[0024] The working principle and usage process of this utility model are as follows: First, take out the center body 101 and place it on the first protective ring 105. Position it by engaging the inner locking buckle 107 with the inner locking groove 102. After engagement, take out the second protective ring 110 and align the outer locking buckle 109 of the locking ring 108 with the outer locking groove 104. Then, fasten it tightly to enclose the center body 101 between the first protective ring 105 and the second protective ring 110, completing the assembly. After that, install it in the position where it is needed and inspect it regularly. Replace the corresponding parts in time if wear or damage occurs.

[0025] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
