Description

Technical Field

[0001] The utility model relates to the technical field of sealing gaskets, in particular to an integrated pipeline sealing gasket. Background Art

[0002] Graphite gaskets are cut or stamped from pure graphite plates or metal-reinforced graphite plates and have numerous excellent sealing properties. The current process uses metal-graphite sealing gaskets that use a metal ring with a sealing graphite ring fixed in a groove. However, during installation and use, pipe deformation and displacement can create shear forces on the graphite, which can easily cause graphite to fall off, affecting the sealing effect of the pipe and making it inconvenient for practical use. Therefore, we have introduced a new integrated pipe sealing gasket. Utility Model Content

[0003] The main purpose of the utility model is to provide an integrated pipeline sealing gasket, which can effectively solve the problems in the background technology.

[0008] Preferably, the two T-shaped positioning blocks are symmetrically distributed front to back, and the two T-shaped positioning blocks are respectively engaged with the two T-shaped positioning grooves.

[0009] By adopting the above technical solution: when the graphite ring is embedded in the groove, the two T-shaped positioning grooves on the graphite ring are respectively engaged with the two T-shaped positioning blocks inside the groove, which not only improves the fixing effect of the graphite ring, but also enables the two limiting clamping columns to be quickly positioned with the two limiting holes respectively, thereby improving the connection efficiency between the graphite ring and the groove.

[0011] By adopting the above technical solution, the limit clamping column can be connected to the spring through the connecting piece, thereby providing elastic potential energy to the limit clamping column.

[0012] Preferably, one end of the two limiting clamping posts close to the connecting piece is respectively inserted and connected with the two inner grooves.

[0013] By adopting the above technical solution, the two limiting clamping columns can squeeze the spring through the limiting piece.

[0014] Preferably, one end of the two limiting clamping columns away from the connecting piece is respectively engaged with the two limiting holes.

[0015] By adopting the above technical solution, when the pipeline is deformed and displaced, the two limiting clamping columns are respectively limited in the two limiting holes, which can prevent the graphite from falling off, thereby improving the sealing effect of the pipeline.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By pressing the two limit clamps, the two limit clamps move into the two inner grooves respectively, compressing the two springs, and then embedding the graphite ring into the groove.

When the pipeline is deformed and displaced, the two limit clamps are respectively limited in the two limit holes to prevent the graphite from falling off, thereby improving the sealing effect of the pipeline;

[0018] 2. When the graphite ring is embedded in the groove, the two T-shaped positioning grooves on the graphite ring are respectively engaged with the two T-shaped positioning blocks inside the groove, which not only improves the fixing effect of the graphite ring, but also enables the two limiting clamping columns to be quickly positioned with the two limiting holes respectively, thereby improving the connection efficiency between the graphite ring and the groove.

[0027] See also Figure 1-4 , the utility model provides a technical solution:

[0028] An integrated pipe sealing gasket comprises a metal ring 1 and a graphite ring 2. A groove 3 is provided at the upper end of the metal ring 1. T-shaped positioning blocks 4 are fixedly connected to the front and rear sides of the outer wall of the groove 3. Limiting holes 5 are provided at the left and right sides of the outer wall of the groove 3. T-shaped positioning grooves 6 are provided at the front and rear sides of the outer surface of the graphite ring 2. Inner grooves 7 are provided at the inner left and right sides of the graphite ring 2. Springs 8 are fixedly connected to the inner walls of the two inner grooves 7. A connecting piece 9 is fixedly connected to the ends of the two springs 8 away from the inner wall of the inner groove 7. A limiting column 10 is fixedly connected to the ends of the two connecting pieces 9 away from the springs 8.

[0029] In this embodiment, the inner wall of the graphite ring 2 fits with the inner wall of the groove 3, and the outer surface of the graphite ring 2 fits with the outer wall of the groove 3. The two T-shaped positioning blocks 4 are symmetrically distributed front to back, and the two T-shaped positioning blocks 4 are respectively engaged with the two T-shaped positioning grooves 6.

[0030] Through the above scheme: when the graphite ring 2 is embedded in the groove 3, the two T-shaped positioning grooves 6 on the graphite ring 2 are respectively engaged with the two T-shaped positioning blocks 4 inside the groove 3, which not only improves the fixing effect of the graphite ring 2, but also enables the two limiting clamping columns 10 to be quickly positioned with the two limiting holes 5 respectively, thereby improving the connection efficiency between the graphite ring 2 and the groove 3.

[0031] In this embodiment, the two limiting holes 5 are symmetrically distributed on the left and right, the two connecting plates 9 are respectively located inside the two inner grooves 7, the two limiting clamping columns 10 are respectively connected to the two inner grooves 7 at one end close to the connecting plate 9, and the two limiting clamping columns 10 are respectively engaged and connected with the two limiting holes 5 at one end away from the connecting plate 9.

[0032] Through the above scheme: by pressing the two limiting clamps 10, the two limiting clamps 10 move toward the inside of the two inner grooves 7 respectively, so that the two springs 8 are compressed, and then the graphite ring 2 is embedded into the inside of the groove 3. When the graphite ring 2 is completely embedded, the two limiting clamps 10 are respectively clamped into the inside of the two limiting holes 5 under the release of the elastic force of the springs 8, so that the graphite ring 2 can be conveniently and quickly fixed in the inside of the groove 3, so that the metal ring 1 and the graphite ring 2 can be conveniently and quickly combined into a metal-graphite composite sealing gasket, and when the pipeline is deformed and displaced, since the two limiting clamps 10 are respectively limited in the two limiting holes 5, the graphite can be prevented from falling off, thereby improving the sealing effect of the pipeline.

[0033] It should be noted that the present invention is an integrated pipe sealing gasket. During use, by pressing the two limit posts 10, the two limit posts 10 will slide inward along the preset inner groove 7 path. During this process, the built-in spring 8 will be compressed and store energy. Afterwards, the graphite ring 2 is placed in the groove 3 until it is fully embedded. Once the graphite ring 2 is in place, the spring 8 releases its stored elastic force, pushing the two limit clamps 10 to bounce into the corresponding limit holes 5 respectively, thereby realizing rapid fixation of the graphite ring 2 in the groove 3, so that the metal ring 1 and the graphite ring 2 can be quickly combined into a metal-graphite composite sealing gasket. In addition, when the graphite ring 2 is embedded in the groove 3, the two T-shaped positioning grooves 6 designed on its surface will accurately match and engage with the two T-shaped positioning blocks 4 pre-set in the groove 3, which not only enhances the fixing stability of the graphite ring 2, but also guides the rapid alignment and connection of the two limit clamps 10 with the limit holes 5, further accelerating the assembly process between the graphite ring 2 and the groove 3, and improving the overall connection efficiency. Even when the pipeline is deformed or displaced, the locking of the limit clamps 10 and the limit holes 5 can effectively prevent the graphite from falling off, ensuring that the sealing effect of the pipeline is not affected.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
