Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a high-temperature resistant silicon carbide ceramic sealing ring component. Background Art

[0002] The sealing ring is an annular seal. It is placed in the ring groove of the sleeve. The sleeve rotates with the shaft. The sealing ring plays a sealing role. All contact surfaces need to be hardened and polished.

[0003] Existing silicon carbide ceramic sealing rings have high temperature resistance. However, when the sealing ring components are spliced ​​together, gaps exist at the joints, so gaskets are generally required to ensure the tightness of the joints. However, when the sealing rings are used in high temperature environments, the gaskets are often made of rubber and are not resistant to high temperatures, which makes the gaskets easily damaged, resulting in poor sealing at the joints and failure of the sealing ring's sealing function, which brings inconvenience to people's use. Therefore, a high-temperature resistant silicon carbide ceramic sealing ring component has been introduced. Utility Model Content

[0004] The purpose of the utility model is to provide a high-temperature resistant silicon carbide ceramic sealing ring assembly, which has the advantage of high-temperature resistance and solves the problem that the existing silicon carbide ceramic sealing ring has high-temperature resistance, but when the sealing ring assembly is spliced ​​for use, due to the presence of gaps at the splicing, it is generally necessary to add a gasket to ensure the tightness of the connection. However, when the sealing ring is used in a high-temperature environment, since the gasket is often made of rubber and is not resistant to high temperatures, the gasket is easily damaged, resulting in poor sealing of the connection, making the sealing function of the sealing ring invalid, and causing inconvenience to people's use.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: A high-temperature resistant silicon carbide ceramic sealing ring assembly, comprising a first ceramic fiber connecting ring, a second ceramic fiber connecting ring provided at the bottom of the first ceramic fiber connecting ring, a sealing gasket provided between the first ceramic fiber connecting ring and the second ceramic fiber connecting ring, a first connecting block fixedly connected to both sides of the first ceramic fiber connecting ring, a second connecting block fixedly connected to both sides of the second ceramic fiber connecting ring, a slot provided at the top of the second connecting block, a clipping strip fixedly connected to a side of the first connecting block away from the second ceramic fiber connecting ring, the bottom of the clipping strip extending through the inner cavity of the slot, a connecting bolt threadedly connected to the bottom of the side of the clipping strip extending through the side of the connecting bolt extending through the side of the second connecting block extending through the side of the first ceramic fiber connecting ring, the sealing gasket comprising a base layer, a reinforcing layer bonded to a surface of the base layer, a high-performance layer bonded to a surface of the reinforcing layer, an elastic layer bonded to a surface of the high-performance layer, and a wear-resistant layer bonded to a surface of the elastic layer.

[0006] Preferably, the base layer is made of natural rubber, and the reinforcement layer is made of polyurethane rubber.

[0007] Preferably, the high-performance layer includes a first high-temperature resistant layer, and a second high-temperature resistant layer is bonded to the surface of the first high-temperature resistant layer.

[0008] Preferably, the first high temperature resistant layer is made of vinyl silicone rubber, and the second high temperature resistant layer is made of low phenyl silicone rubber.

[0009] Preferably, the elastic layer is made of butadiene rubber, and the wear-resistant layer is made of nitrile rubber.

[0010] Preferably, threaded holes adapted to the connecting bolts are formed on the bottom of the clamping strip away from the first ceramic fiber connecting ring and on the side of the second connecting block away from the first ceramic fiber connecting ring, and the two threaded holes are connected.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] 1. The utility model can make the sealing gasket have high temperature resistance through the first high temperature resistant layer and the second high temperature resistant layer. When used in a high temperature environment, it will not be damaged, ensuring the tightness of the connection between the first ceramic fiber connecting ring and the second ceramic fiber connecting ring, which is convenient for people to use.

[0013] 2. The utility model provides a reinforcing layer to make the sealing gasket have higher usage strength.
