Description

Technical Field

[0001] The utility model relates to the field of sealing rings, in particular to an adjustable sealing ring. Background Art

[0002] Sealing rings are widely used in various equipment and containers due to their good elasticity and water resistance. When the sealing ring is in use, the height of the sealing ring has a great direct relationship with its sealing performance. If the height of the sealing ring is too low, it may not provide sufficient compression, resulting in a loose seal and easy leakage. Therefore, providing a height-adjustable sealing ring has become an urgent problem to be solved. Utility Model Content

[0003] 1. Technical issues to be resolved

[0004] In order to solve the above problems in the prior art, the utility model provides an adjustable sealing ring.

[0005] (II) Technical solution

[0006] In order to achieve the above-mentioned purpose, the main technical solutions adopted by the utility model include:

[0007] An adjustable sealing ring comprises a sealing ring body and a metal gasket;

[0008] The metal washer has an annular structure, and an annular protrusion is provided on the top and bottom of the metal washer;

[0009] The upper and lower sides of the sealing ring body are both provided with an annular connecting groove adapted to the annular protrusion.

[0010] Adjacent sealing ring bodies are connected via the metal gaskets.

[0011] Preferably, the longitudinal section of the annular protrusion is a T-shaped structure.

[0012] Preferably, the annular protrusion and the connecting groove are connected by an adhesive.

[0013] Preferably, the inner and outer diameters of the metal gasket are the same as the outer diameter of the sealing ring body.

[0014] (III) Beneficial effects

[0015] The beneficial effect of the utility model is that: by adopting the above technical scheme, the sealing ring body can be used alone. If the height of the sealing ring body is insufficient, the two sealing ring bodies can be combined together by a metal gasket to increase the height of the sealing ring so that it can provide sufficient compression to ensure the sealing effect. After adding the metal gasket, the service life of the sealing ring can be improved due to the high wear resistance and corrosion resistance of the metal gasket, and the metal gasket can enhance the sealing performance of the sealing ring, especially in high pressure or high temperature environment, the high hardness and precision of the metal gasket can ensure a tighter fit and reduce the possibility of leakage.

[0022] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0023] Please refer to Figures 1 to 3 , the first embodiment of the utility model:

[0024] An adjustable sealing ring comprises a sealing ring body 1 and a metal gasket 2;

[0025] The metal washer 2 is an annular structure, and an annular protrusion 21 is provided on the top and bottom of the metal washer 2;

[0026] The upper and lower sides of the sealing ring body 1 are both provided with an annular connecting groove 11 adapted to the annular protrusion 21.

[0027] Adjacent sealing ring bodies 1 are connected via the metal gaskets 2;

[0028] When in use, the sealing ring body 1 can be used alone. If the height of the sealing ring body 1 is insufficient, the two sealing ring bodies 1 can be combined together through the metal gasket 2 to increase the height of the sealing ring so that it can provide sufficient compression to ensure the sealing effect. After adding the metal gasket 2, the metal gasket 2 has high wear resistance and corrosion resistance, which can increase the service life of the sealing ring, and the metal gasket 2 can enhance the sealing performance of the sealing ring, especially in high pressure or high temperature environments, the high hardness and precision of the metal gasket can ensure a tighter fit and reduce the possibility of leakage.

[0029] In this embodiment, the longitudinal section of the annular protrusion 21 is in a T-shaped structure, and the connection between the annular protrusion 21 in the T-shaped structure and the connecting groove 11 is more firmly connected.

[0030] In this embodiment, the annular protrusion 21 is connected to the connecting groove 11 by an adhesive, and the adhesive ensures the firmness of the connection between the sealing ring body 1 and the metal gasket 2 .

[0031] In this embodiment, the inner and outer diameters of the metal gasket 2 are the same as the outer diameter of the sealing ring body 1 .

[0032] The working principle of the utility model is as follows:

[0033] The sealing ring body 1 can be used alone. If the height of the sealing ring body 1 is insufficient, two sealing ring bodies 1 can be combined together through a metal gasket 2 to increase the height of the sealing ring so that it can provide sufficient compression to ensure the sealing effect. After adding the metal gasket 2, the metal gasket 2 has high wear resistance and corrosion resistance, which can increase the service life of the sealing ring, and the metal gasket 2 can enhance the sealing performance of the sealing ring, especially in high pressure or high temperature environments. The high hardness and precision of the metal gasket can ensure a tighter fit and reduce the possibility of leakage.
