Description

Technical Field

[0001] The present application relates to the technical field of sealing elements, and in particular to a sealing ring. Background Art

[0002] A reactor is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process can be achieved. High-pressure reactors have higher requirements for the sealing of the reactor cover, and sealing rings are often used to improve the sealing performance of the reactor cover.

[0003] In the prior art, for example, the Chinese patent document publication number is CN214020707U, and the patent name is a safety sealing structure for a reactor, wherein the reactor comprises a reactor body and a reactor cover movably arranged on the reactor body, and further comprises a driving device and a heat-deformable sealing member, wherein the sealing member is arranged between the reactor cover and the reactor body. The sealing member rapidly expands at the connection between the plug-in end and the reactor body through the heat circulation loop in the reactor body, thereby directly sealing the reactor body.

[0004] Regarding the above-mentioned related technologies, the edge of the above-mentioned seal is a vertical structure, and then placed in the cavity to achieve sealing. However, due to the general clearance fit during the placement process, it is difficult for the sealing ring to achieve a sufficient sealing effect, and there will be a gap between the edge of the sealing ring and the cavity. Therefore, the sealing ring needs to be further improved. Utility Model Content

[0005] In order to improve the sealing effect of the seal in the reactor, the present application provides a sealing ring.

[0032] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.

[0033] The present application embodiment discloses a sealing ring. Figure 1 and Figure 2 The sealing ring includes a sealing ring body 1, which is made of plastic material. The plastic material may be, but is not limited to, polyvinyl chloride, polystyrene, etc. These hard plastic materials have the advantages of light weight, low cost, safety and non-toxicity, so that the sealing ring body 1 is light in weight and easy to carry, while reducing the manufacturing cost. Among them, the outer surface of the sealing ring body 1 is polished, and the surface of the sealing ring body 1 after polishing has good smoothness, which can improve the comfort of the staff when holding it.

[0034] The sealing ring body 1 is provided with a circular cavity 2, so that the sealing ring body 1 is in the shape of a closed circular ring. One side of the sealing ring body 1 is a sealing surface 3, and the other side is a contact surface 4. Among them, the sealing ring body 1 is provided with a first outer gap 5 and a first inner gap 6, both of which are located on the side where the sealing surface 3 is located, and both of the first inner gap 6 and the first outer gap 5 are arranged along the circumference of the sealing ring body 1. The first inner gap 6 is located on the inner ring of the sealing ring body 1, and the first outer gap 5 is located on the outer ring of the sealing ring body 1, and the diameter of the first outer gap 5 is greater than the diameter of the first inner gap 6.

[0035] When in use, the sealing surface 3 of the sealing ring body 1 faces the kettle body, so that the sealing surface 3 is in contact with the high-temperature and high-pressure gas. After the gas enters the first outer gap 5 and the first inner gap 6, the arc angle of the edge of the sealing ring body 1 can be appropriately expanded, so that the sealing ring fits more closely with the inner wall of the cavity, reducing the possibility of gas leakage and improving the sealing effect.

[0036] In some embodiments, reinforcing sheets 7 are arranged at intervals along the circumferential direction in the first outer gap 5, and reinforcing sheets 7 are arranged at intervals along the circumferential direction in the first inner gap 6. The reinforcing sheets 7 can increase the structural strength of the first outer gap 5 and the first inner gap 6, and extend the service life. The reinforcing sheets 7 are made of stainless steel. The reinforcing sheets 7 made of stainless steel have good strength on the one hand and are not prone to bending and breaking; on the other hand, they have good corrosion resistance, reduce the possibility of rusting of the reinforcing sheets 7, and extend the service life.

[0037] In addition, the sealing ring body 1 is provided with a mounting groove 8, which is located on the side where the sealing surface 3 is located, and is used for plugging in an external plug-in block. The external plug-in block is plugged into the mounting groove 8 on the sealing ring body 1, and the position of the sealing ring body 1 is restricted by the action of friction, thereby reducing the displacement of the sealing ring body 1 and improving stability. An anti-slip layer (not shown in the figure) is also provided in the mounting groove 8, and the anti-slip layer is made of an anti-slip material, which can be but is not limited to rubber. The anti-slip layer can increase the static friction between the sealing ring body 1 and the external plug-in block, and improve the stability of the sealing ring body 1 after installation.

[0038] The implementation principle of a sealing ring in an embodiment of the present application is as follows: the sealing ring body 1 is installed between the kettle cover and the kettle body. When in use, the sealing surface 3 of the sealing ring body 1 faces the kettle body, so that the sealing surface 3 is in contact with the high-temperature and high-pressure gas. After the gas enters the first outer gap 5 and the first inner gap 6, the arc angle of the edge of the sealing ring body 1 can be appropriately stretched, so that the sealing ring fits more closely with the inner wall of the cavity, reducing the possibility of air leakage and improving the sealing effect.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
