Problems solved by technology
[0004] The purpose of the present invention is to provide a machine sealing device made of carbon composite material to solve the problem that in the current common pipeline sealing proposed in the above background technology, due to the high corrosion of parts in the sealing environment, after a long time of sealing, it will cause The parts are corroded and rusted, which leads to the failure of the seal, and the fireproof, moisture-proof, corrosion resistance and other properties of the existing sealing materials are relatively general, especially the rubber ring and the welding place often fail. Once there is a problem with the sealing material, it will causing many inconveniences

The invention discloses a machine sealing device made of carbon composite material, comprising a sealing cover plate, a sealing device outer shell and a sealing base, a control valve is arranged at the middle position of the top end of the sealing cover plate, and the sealing cover plate It is fixedly connected with the control valve, a fixed seat is provided at the middle position of the bottom end of the sealing cover, the sealing cover is fixedly connected with the fixed seat, a fixed rod is arranged on the fixed seat, and the fixed seat and the fixed rod Fixedly connected, a sealing base is provided under the sealing cover, the sealing base is fixedly connected with the sealing cover, and a fixed beam is provided at the middle of the sealing base. This sealing device not only solves the problem of the original The fireproof, moistureproof, corrosion resistance and other properties of the sealing material are relatively general, and they are easy to corrode and rust, resulting in the problem of sealing failure. At the same time, two methods are combined to achieve the purpose of complementing each other, making it more reasonable and safe, and the sealing performance is more stable. .
Description
technical field [0001] The invention belongs to the technical field of machine sealing devices, and in particular relates to a machine sealing device made of carbon composite materials. Background technique [0002] There are two preparation methods for carbon-based composites: one is the impregnation method, that is, the molten petroleum or coal tar pitch is impregnated with reinforcements, and then treated with carbonization and graphite. Its matrix is graphite carbon, which is in a layered strip structure, and its performance is anisotropic. There is also a thermosetting resin such as furfuryl alcohol or phenolic formaldehyde impregnated with a reinforcement, and only after carbonization treatment, its matrix is glassy carbon, that is, an amorphous carbon structure, and its performance is isotropic; the other is the CVD method, that is, the heat of hydrocarbon compounds The carbon matrix of this method is pyrolytic carbon similar to glassy carbon, and the carbon comp...
