Technical Field

[0001] This utility model relates to the field of sealing gasket technology, and in particular to a modular sealing gasket. Background Technology

[0002] In industrial equipment, piping connections, and mechanical assembly, gaskets are critical components for preventing fluid or gas leakage. Traditional gaskets are typically single-layer, integral structures, and their sealing performance deteriorates over time due to wear, corrosion, or aging, necessitating replacement of the entire gasket.

[0003] This design has the following drawbacks:

[0004] 1. Even if only a portion of the gasket is worn, the entire gasket still needs to be discarded, increasing resource consumption;

[0005] 2. A single material cannot simultaneously meet multiple requirements such as high temperature resistance, corrosion resistance, and elastic sealing.

[0006] To address these issues, those skilled in the art have provided a modular sealing gasket. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides a modular sealing gasket that solves the problems mentioned in the background section.

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0009] A modular sealing gasket includes a first gasket layer, which is annular and made of stainless steel; and a second gasket layer, which is located above the first gasket layer and made of synthetic rubber. The first and second gasket layers are in a movable engagement relationship, and an engagement structure is provided between them. The engagement structure includes an engagement groove formed on the side of the first gasket layer near the second gasket layer, an engagement ring provided at the bottom of the second gasket layer, the engagement ring being movably engaged in the engagement groove, and an anti-slip protrusion for limiting and preventing slippage between the first and second gasket layers.

[0010] According to the modular sealing gasket, the retaining ring is made of the same material as the second gasket layer, and the cross-section of the retaining ring is arrow-shaped.

[0011] According to the modular sealing gasket, the anti-slip protrusions are disposed at the bottom end of the second gasket layer. There are multiple sets of anti-slip protrusions, which are located on both sides of the locking ring and are distributed in a ring array on the second gasket layer.

[0012] According to the modular sealing gasket, the second gasket layer, the retaining ring, and the anti-slip protrusion are integrally formed.

[0013] According to the modular sealing gasket, the cross-section of the engagement groove is arrow-shaped, and the engagement groove is located below the engagement ring.

[0014] According to the modular sealing gasket, the top of the first gasket layer is also provided with multiple sets of anti-slip engagement holes, which are located on both sides of the engagement groove and are distributed in a ring array on the first gasket layer.

[0015] According to the modular sealing gasket, the number of anti-slip protrusions corresponds one-to-one with the anti-slip engagement holes, and the anti-slip protrusions can be movably engaged in the corresponding anti-slip engagement holes.

[0016] This utility model provides a modular sealing gasket with the following advantages: The modular sealing gasket of this application consists of two layers, a first gasket layer and a second gasket layer. An engaging structure is provided between the first gasket layer and the second gasket layer, and the second gasket layer can be locked in place with the first gasket layer. After a period of use, the sealing gasket can be removed. When it is found that some areas of the second gasket layer are worn, the second gasket layer can be replaced separately, which effectively reduces the later maintenance costs, saves costs and extends the service life.

[0028] Please see Figure 1-5 As shown, this utility model is a modular sealing gasket, including a first gasket layer 10, which is annular and made of stainless steel; a second gasket layer 11, which is located above the first gasket layer 10 and is made of synthetic rubber; the first gasket layer 10 and the second gasket layer 11 are in a movable engaging relationship, and an engaging structure is provided between them; the engaging structure includes an engaging groove 14 formed on the side of the first gasket layer 10 near the second gasket layer 11, an engaging ring 12 provided at the bottom of the second gasket layer 11, the engaging ring 12 being movable and engaging in the engaging groove 14, and an anti-slip protrusion 13 for limiting and preventing slippage between the first gasket layer 10 and the second gasket layer 11.

[0029] Specifically, the modular sealing gasket of this application consists of two layers: a first gasket layer 10 and a second gasket layer 11. An engaging structure is provided between the first gasket layer 10 and the second gasket layer 11, allowing the second gasket layer 11 to engage with the first gasket layer 10. After a period of use, the sealing gasket can be removed. When wear is found in a portion of the second gasket layer 11, the second gasket layer 11 can be replaced separately, effectively reducing later maintenance costs, saving costs, and extending service life.

[0030] Among them, such as Figure 1-2 As shown, the locking ring 12 and the second gasket layer 11 are made of the same material, and the cross-section of the locking ring 12 is arrow-shaped. Anti-slip protrusions 13 are provided at the bottom end of the second gasket layer 11. Multiple sets of anti-slip protrusions 13 are located on both sides of the locking ring 12, and are arranged in a ring array on the second gasket layer 11. The second gasket layer 11, the locking ring 12, and the anti-slip protrusions 13 are integrally formed.

[0031] Specifically, the cross-section of the locking ring 12 is arrow-shaped, and multiple sets of anti-slip protrusions 13 are set at the bottom of the second gasket layer 11 and located on both sides of the locking ring 12. The second gasket layer 11, the locking ring 12 and the anti-slip protrusions 13 are integrally formed, which facilitates installation and replacement.

[0032] Among them, such as Figure 3-4 As shown, the cross-section of the locking groove 14 is arrow-shaped, and the locking groove 14 is located below the locking ring 12. The top of the first gasket layer 10 also has multiple sets of anti-slip locking holes 15, which are located on both sides of the locking groove 14 and are arranged in a ring array on the first gasket layer 10.

[0033] Specifically, by setting the cross-section of the locking groove 14 to be "arrow" shaped, the locking ring 12 can be movably locked in the locking groove 14. By also opening multiple sets of anti-slip locking holes 15 at the top of the first gasket layer 10, the multiple sets of anti-slip locking holes 15 are located on both sides of the locking groove 14, and the multiple sets of anti-slip locking holes 15 are distributed in a ring array on the first gasket layer 10, which facilitates the anti-slip protrusion 13 to be locked in the corresponding anti-slip locking hole 15.

[0034] Among them, such as Figure 5 As shown, the number of anti-slip protrusions 13 corresponds one-to-one with the anti-slip engaging holes 15, and the anti-slip protrusions 13 can be movably engaged in the corresponding anti-slip engaging holes 15.

[0035] Specifically, by setting the number of anti-slip protrusions 13 to correspond one-to-one with the anti-slip engagement holes 15, the anti-slip protrusions 13 are movably engaged in the corresponding anti-slip engagement holes 15, thereby limiting and fixing the second gasket layer 11, preventing the second gasket layer 11 from rotating and sliding during use, which could cause local sealing leakage.

[0036] The specific working principle of this modular sealing gasket is as follows: the cross-section of the locking ring 12 is arrow-shaped, and multiple sets of anti-slip protrusions 13 are set at the bottom of the second gasket layer 11 and located on both sides of the locking ring 12. The second gasket layer 11, the locking ring 12, and the anti-slip protrusions 13 are integrally formed, which facilitates installation and replacement. After a period of use, the sealing gasket can be removed. When it is found that some areas of the second gasket layer 11 are worn, the second gasket layer 11 can be replaced separately, which effectively reduces the later maintenance costs, saves costs, and extends the service life. By setting the number of anti-slip protrusions 13 to correspond one-to-one with the anti-slip locking holes 15, the anti-slip protrusions 13 are movably locked in the corresponding anti-slip locking holes 15, thereby limiting and fixing the second gasket layer 11 and preventing the second gasket layer 11 from rotating and sliding during use, causing local sealing leakage.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
