Description

Technical Field

[0001] This utility model belongs to the field of sealing element technology, and in particular relates to a double-layer structure sealing gasket. Background Technology

[0002] Existing gaskets (such as rubber gaskets, metal flat gaskets, or graphite composite gaskets) generally have the following problems in industrial applications: traditional gaskets mostly adopt a single-layer structure, focusing only on sealing performance and lacking buffering and shock absorption functions. They are prone to deformation or creep under high pressure, vibration, or temperature fluctuation conditions, leading to sealing failure. Utility Model Content

[0003] The technical problem this invention aims to solve is that traditional single-layer gaskets only focus on sealing performance and lack buffering and shock absorption functions. Under high pressure, vibration or temperature fluctuation conditions, they are prone to deformation or creep, leading to sealing failure.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a double-layer sealing gasket, comprising a gasket body, wherein the gasket body is arranged in a circular shape and its interior is hollow, and further comprising...

[0005] A buffer assembly, located inside the gasket body, includes a stainless steel mesh fixedly connected to the inner wall of the gasket body, with partitions fixedly connected between the inner walls of the stainless steel mesh, and buffer mechanisms symmetrically distributed between the partitions and the stainless steel mesh.

[0006] Furthermore, the buffer mechanism includes buffer columns located between the stainless steel mesh and the partition, and the buffer columns are arranged in a ring. Multiple sets of buffer columns are provided, and an inner cavity is provided inside the buffer column. The inner cavity is wider on both sides and narrower in the middle.

[0007] Furthermore, the top wall of the partition is fixedly connected with symmetrically distributed limiting blocks, and the middle part of the top wall of the partition is fixedly connected with a locking block. The buffer column is located between the locking block and the limiting block, and both the locking block and the limiting block are arranged in a circular shape.

[0008] Furthermore, symmetrically distributed limiting rings are fixedly connected to the inner wall of the stainless steel mesh, and the buffer column is located between the opposite side walls of the limiting rings.

[0009] Furthermore, the interior cavity is filled with a non-Newtonian fluid.

[0010] Furthermore, the limiting ring, the limiting block, and the locking block all have C-shaped cross-sections.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows:

[0012] (1) Stainless steel mesh is used to provide rigid support for the whole structure;

[0013] (2) The partition can divide the internal space into two, separating the buffer space, and the upper and lower parts can be buffered separately without delaying either.

[0014] (3) The deformation of the buffer column compresses the non-Newtonian fluid inside the cavity, and the close contact of the three buffer columns gives it a good buffering effect.

[0015] (4) Limiting blocks, locking blocks and limiting rings can restrict the position of the buffer column to prevent it from shifting after the buffer absorbs energy, and can also reduce the overall deformation. Attached Figure Description

[0021] like Figure 1-2 As shown, a double-layer sealing gasket includes a gasket body 1, which is arranged in a circular shape and has a hollow interior, and also includes a buffer assembly disposed inside the gasket body 1.

[0022] like Figure 1-3As shown, in order to make the gasket body 1 have a buffering effect and prevent it from deforming or creeping under high pressure, vibration or temperature fluctuation conditions, the buffer assembly includes a stainless steel mesh 2 fixedly connected to the inner wall of the gasket body 1. A partition 3 is fixedly connected between the inner walls of the stainless steel mesh 2. A buffer mechanism is provided between the partition 3 and the stainless steel mesh 2, which is symmetrically distributed vertically. The buffer mechanism includes buffer columns 4 located between the stainless steel mesh 2 and the partition 3, which are arranged in a ring. There are three sets of buffer columns 4, and each has an inner cavity 5. The inner cavity 5 is wider on both sides and narrower in the middle. The inner cavity 5 is filled with a non-Newtonian fluid. The partition 3 divides the internal space into two, separating the buffer space. The upper and lower parts can be buffered separately without delay. The deformation of the buffer column 4 compresses the non-Newtonian fluid inside the inner cavity 5. The close contact of the three buffer columns 4 gives it a good buffering effect.

[0023] In order to limit the rubber column, the top wall of the partition 3 is fixedly connected with symmetrically distributed limiting blocks 6, and the middle of the top wall of the partition 3 is fixedly connected with a locking block 7. The buffer column 4 is located between the locking block 7 and the limiting block 6. The locking block 7 and the limiting block 6 are both arranged in a circular shape. The inner wall of the stainless steel mesh 2 is fixedly connected with symmetrically distributed limiting rings 8. The buffer column 4 is located between the opposite side walls of the limiting rings 8. The limiting rings 8, the limiting blocks 6 and the locking block 7 are all arranged in a C-shape.

[0024] In practical use, the stainless steel mesh 2 provides rigid support for the interior of the gasket body 1, and the partition 3 divides the internal space into two, separating the buffer space so that the upper and lower parts can be buffered separately without delay. The buffer column 4 can be made of rubber. When subjected to external force, the deformation of the buffer column 4 compresses the non-Newtonian fluid inside the inner cavity 5. The close contact of the three buffer columns 4 gives it a good buffering effect. The limiting block 6, the locking block 7, and the limiting ring 8 can limit the position of the buffer column 4 to prevent displacement after buffering and absorbing energy, and also reduce the overall deformation.

In conclusion, if those skilled in the art, inspired by this description, design similar structural methods and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
