Description
Technical Field
[0001] The utility model relates to the technical field of mechanical sealing mechanisms, in particular to a high-temperature resistant spring-type mechanical sealing mechanism. Background Art
[0002] A sealing device is a component or combination of components used to prevent fluids or solid particles from leaking from adjacent mating surfaces or to prevent external impurities such as dust and moisture from invading the interior of machinery and equipment. In the rapidly developing modern industry, it is necessary to seal between shafts and equipment to prevent the medium from leaking from the circumferential gap between the shafts and equipment. The mechanical sealing device includes a dynamic ring that can rotate with the shaft. The operating environment of mechanical seals is undergoing profound changes, and the requirements for their working conditions are more stringent.
[0003] The existing mechanical sealing devices have poor sealing effects and may leak after long-term use. Secondly, some mechanical sealing devices do not have springs to increase the connection force in the reinforcement mechanism, resulting in poor use effects and urgent need for development.

[0010] The beneficial technical effects of this technical solution are as follows:
[0011] The present application can effectively prevent water leakage after long-term use of the seal by setting and co-using a waterproof sealing rubber pad and a high-temperature resistant spring body. At the same time, it can effectively improve the connection force of each thread after the fastening bolt is connected when the high-temperature resistant spring body is used for reinforcement, thereby effectively improving the connection effect. The sealing device can be effectively reinforced by the setting of the fastening bolts, and the designed embedded screw holes can effectively prevent the fastening bolts from protruding after connection to hinder the reinforced connection.

[0012] This application increases the support area of the high-temperature resistant spring body by setting upper and lower support platforms on the upper and lower sides of the high-temperature resistant spring body, while also increasing the friction force of the contact surface between the high-temperature resistant spring body and mechanical parts, making the connection between the two tighter and effectively improving the stability of the high-temperature resistant spring body.
[0013] The present application can improve the corrosion resistance of the high-temperature resistant spring body by wrapping the anti-corrosion layer, and achieve a double-layer anti-corrosion effect in combination with the anti-corrosion sealant layer, thereby extending the service life of the high-temperature resistant spring body. The high-temperature resistant outer layer is in a wrapped shape, and combined with the high-temperature resistant coating layer set on the outside of the high-temperature resistant spring body, it can increase the high-temperature resistance of the high-temperature resistant spring body, so that it can be used in a high-temperature environment and improve its service life.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0021] See also Figure 1-5 The utility model provides an embodiment: a high-temperature resistant spring type mechanical sealing mechanism, including a mechanical sealing platform 1, a high-temperature resistant spring body 3, a buffering and fixing gasket 7 and a fastening bolt 8. The top surface of the mechanical sealing platform 1 is connected with a buffering and fixing gasket 7, and the high-temperature resistant spring body 3 is arranged inside the buffering and fixing gasket 7. The top of the buffering and fixing gasket 7 is provided with a waterproof sealing rubber pad 6. The arrangement and coordinated use of the waterproof sealing rubber pad 6 and the high-temperature resistant spring body 3 can effectively prevent water leakage after long-term use of the seal, and when reinforced by the high-temperature resistant spring body 3, the connection force of each thread after the fastening bolt 8 is connected can be effectively improved, thereby effectively improving the connection effect.
[0022] An upper sealing ring 5 is provided on the top of the waterproof sealing rubber pad 6, and a mounting positioning ring 4 is provided on the top of the upper sealing ring 5. A lower sealing cover 9 is provided on the bottom surface of the mechanical sealing platform 1. The internal annular array of the mechanical sealing platform 1 has embedded screw holes 15 and movable grooves 17. Matching fastening bolts 8 are provided in the embedded screw holes 15. The setting of the fastening bolts 8 can effectively reinforce the sealing device, and the designed embedded screw holes 15 can effectively prevent the fastening bolts 8 from protruding after connection to hinder the reinforced connection.
[0023] The top and bottom of the high-temperature resistant spring body 3 are connected to the upper and lower support platforms 2. The upper and lower support platforms 2 arranged on the upper and lower sides of the high-temperature resistant spring body 3 can increase the support area of the high-temperature resistant spring body 3, and also increase the friction force of the contact surface between the high-temperature resistant spring body 3 and the mechanical parts, making the connection between the two tighter.
[0024] The outer surface of the high-temperature resistant spring body 3 is connected to an anti-corrosion sealant layer 10, and the outer surface of the anti-corrosion sealant layer 10 is connected to an anti-corrosion layer 11. The anti-corrosion layer 11 is in a wrapped shape, which can improve the corrosion resistance of the high-temperature resistant spring body 3, and cooperate with the anti-corrosion sealant layer 10 to achieve a double-layer anti-corrosion effect, thereby extending the service life of the high-temperature resistant spring body 3.
[0025] The outer surface of the anti-corrosion layer 11 is connected to the heat-insulating layer 12, and the outer surface of the heat-insulating layer 12 is connected to the high-temperature resistant coating layer 13. The outer surface of the high-temperature resistant coating layer 13 is connected to the high-temperature resistant outer layer 14. The high-temperature resistant outer layer 14 is in a wrapped shape. In combination with the high-temperature resistant coating layer 13 provided on the outer side of the high-temperature resistant spring body 3, the high-temperature resistance effect of the high-temperature resistant spring body 3 can be increased, allowing it to be used in high-temperature environments and extending its service life.
[0026] A stopper 16 is installed within the movable groove 17. Both sides of the movable groove 17 are connected to stopper grooves 19 that match the stopper 16. The stopper 16 is connected to the inner surface of the movable groove 17 via an expansion spring 20. During installation of the mechanical seal platform 1, the expansion of the expansion spring 20 allows the friction-increasing block 18 to maintain close contact with the contact mechanism surface for a long period of time, increasing the contact area and achieving a more stable and reinforced connection. The friction-increasing block 18 is connected to the upper surface of the stopper 16.
[0027] The working principle of this equipment is as follows: the upper and lower support platforms 2 arranged on the upper and lower sides of the high-temperature resistant spring body 3 can increase the support area of the high-temperature resistant spring body 3, and also increase the friction between the contact surface between the high-temperature resistant spring body 3 and the mechanical parts, making the connection between the two tighter. The setting and coordinated use of the waterproof sealing rubber pad 6 and the high-temperature resistant spring body 3 can effectively prevent water leakage after long-term use of the seal, and when reinforced by the high-temperature resistant spring body 3, it can effectively improve the connection force of each thread after the fastening bolt 8 is connected, effectively improving the connection effect. The sealing device can be effectively reinforced by the setting of the fastening bolt 8, and the designed embedded screw hole 15 can effectively prevent the fastening bolt 8 from bulging after connection to hinder the reinforced connection. During the installation of the mechanical sealing platform 1, the expandability of the expansion connecting spring 20 enables the friction-increasing block 18 to maintain friction-increasing close contact with the surface of the contact mechanism for a long time.
