Description

Technical Field

[0001] The utility model relates to the technical field of sealing components, in particular to a high temperature resistant rubber sealing component. Background Art

[0002] Seals are materials or parts that prevent fluids or solid particles from leaking between adjacent mating surfaces and prevent external impurities such as dust and moisture from invading the internal parts of machinery and equipment. They are one of the basic components and accessories in major national economic industries such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing. In particular, the production scale of the rubber seal manufacturing industry continues to grow, and it occupies a very important position in the development of the national economy.

[0003] When in use, rubber seals are required to have high high temperature resistance in high temperature environments to improve their durability. Traditional high temperature resistant rubber seals still have some problems when in use. First, some existing high temperature resistant rubber seals are mainly closed connections when connected to objects that need to be sealed. When the heat is high, the temperature accumulates at the connection for a long time, and heat dissipation is inconvenient, which can easily cause damage to the seals and reduce the service life of the seals. Secondly, after long-term use, the rubber material of some existing rubber seals is prone to relaxation and shrinkage, and the sealing effect of the sealed connection is easily reduced. In addition, the cost of continuous replacement and maintenance is high, which reduces the use effect. Utility Model Content

[0029] A high temperature resistant rubber seal provided by some embodiments of the utility model is described below in conjunction with the accompanying drawings.

[0030] Embodiment 1:

[0031] Combination Figure 1-Figure 3 As shown, the utility model provides a high temperature resistant rubber seal.

[0032] Specifically, it includes a sealing body 1, a sealing convex ring 2 is sleeved on the outer side of the sealing body 1, a heat-conducting compression component 4 is embedded and installed on the inner side of the connection between the sealing convex ring 2 and the sealing body 1, and the heat-conducting compression component 4 is respectively composed of a heat-conducting clamping plate 401, a slide groove 402, a first metal gasket 403, an extrusion ejector rod 404, a compression chamber 405 and a sealing compression plunger 406. The slide groove 402 is mainly used to facilitate the movement of the first metal gasket 403. One end of the heat-conducting compression component 4 is located on the inner side of the sealing body 1 and is embedded and clamped with a rubber sealing ring 5. The sealing convex ring 2 An inner mounting groove 6 is provided on the inner side of the inner mounting groove 6, which is mainly for facilitating the installation of various components, and at the same time facilitates the heat conduction compression component 4 to guide the heat therein, so as to facilitate the subsequent heat dissipation. A plurality of groups of transverse heat dissipation vents 3 are provided on the outer side of the sealing convex ring 2, and a porous compression air bag 8 is provided on the inner side of the inner mounting groove 6 corresponding to the plurality of groups of heat dissipation vents 3. A second metal gasket 11 is connected to one end of the porous compression air bag 8. The second metal gasket 11 and the first metal gasket 403 are mainly for facilitating the installation of the metal spring 7, and at the same time facilitate the respective installation of the porous compression air bag 8 and the extrusion top The rod 404 is squeezed, and the other end is connected with a plurality of heat dissipation holes 3. A plurality of metal springs 7 are evenly installed between the second metal gasket 11 and the first metal gasket 403. A plurality of compression holes 12 are correspondingly provided at the connection point between the second metal gasket 11 and the porous compression airbag 8. A vent hole 10 is provided on one side of the rubber sealing ring 5 and the abutting surface of the heat-conducting compression component 4. The compression chamber 405 is connected with the inside of the rubber sealing ring 5 through the vent hole 10. The porous compression airbag 8, the heat dissipation holes 3, the compression holes 12 and the inner mounting groove 6 are all connected with each other. The slide groove 40 2 is opened at the end surface of the heat-conducting card plate 401 located inside the inner installation groove 6, and the first metal gasket 403 is slidably connected to the inner side of the slide groove 402. The operation and use of the above-mentioned components allows the heat accumulated in the connection of the seal to be transferred to the metal spring 7 through the guidance of the heat-conducting card plate 401 composed of the heat-conducting compression component 4, so that the metal spring 7 is continuously contracted and stretched due to the heat expansion, squeezing the porous compression airbag 8, and the heat in the inner installation groove 6 is discharged to the outside through the heat dissipation vents 3, thereby improving the heat dissipation effect, reducing the damage to the seal by heat, and increasing the service life of the seal.

[0033] Embodiment 2:

[0034] Combination Figure 2-Figure 3 As shown, based on the first embodiment,

[0035] Specifically, one end of the extrusion push rod 404 is connected to the first metal gasket 403, and the other end is connected to the sealing compression plunger 406. The compression chamber 405 is opened inside the middle part of the heat conductive clamping plate 401, and the sealing compression plunger 406 is sealingly and slidably connected to the compression chamber 405. The above-mentioned components, including the contraction and extension of the metal spring sheet 7 in the first embodiment, make the sealing compression plunger 406 expand and contract in the compression chamber 405, and make the gas fill into the rubber sealing ring 5, which actually expands continuously and increases the sealing performance. Such components improve the sealing effect of the seal, reduce the replacement cost, and improve the use effect.

[0036] Combination Figure 2 As shown, in the above embodiment,

[0037] Specifically, sealing connection threaded sleeves 9 are symmetrically embedded and clamped at both ends of the inner side of the sealing body 1. The sealing connection threaded sleeves 9 are mainly used to facilitate the connection and installation of the sealing member.

[0038] The working principle and use process of the utility model are as follows: First, when the seal is in use and the temperature is too high due to the heat generated at the connection, the heat is guided by the heat-conducting card plate 401 composed of the heat-conducting compression assembly 4, and is conducted to the multiple groups of metal springs 7 through the first metal gasket 403 slidably connected to the heat-conducting card plate 401. Due to the principle of thermal expansion and contraction, the metal springs 7 continuously shrink and stretch, and squeeze the porous compression airbag 8, so that it also continuously shrinks and stretches. In this way, through the connection of the compression hole 12 on the second metal gasket 11, the porous compression airbag 8 discharges the heat in the inner mounting groove 6 to the outside through the heat dissipation vent 3, and at the same time External gas can be introduced into the interior to circulate and cool down the heat, which not only improves the heat dissipation effect, reduces the damage of heat to the seal, but also increases the service life of the seal. Secondly, during use, when the above-mentioned components are in operation, especially the metal spring sheet 7 is continuously contracted and stretched, the first metal gasket 403 composed of the heat-conducting compression component 4 is squeezed and squeezed. The top rod 404 causes the sealing compression plunger 406 connected at the bottom to move and retract in the compression chamber 405, generating a compressed airflow and pressing it into the interior of the rubber sealing ring 5 through the vent hole 10, causing it to expand, thereby increasing the sealing performance, reducing the replacement and maintenance costs, and improving the use effect.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
