Description

Technical Field

[0001] This utility model relates to the field of Teflon gasket technology, specifically a high-pressure resistant Teflon gasket. Background Technology

[0002] Teflon gaskets are sealing elements made of polytetrafluoroethylene (PTFE, commonly known as Teflon). They have excellent chemical resistance, high temperature resistance, low coefficient of friction and insulation properties, and are widely used in industrial, chemical, food, and pharmaceutical fields.

[0003] Existing Teflon gaskets have the following problems:

[0004] The compressive strength of Teflon gaskets is a key consideration in their application. However, existing Teflon gaskets have poor compressive strength and are prone to plastic deformation under continuous pressure, leading to seal failure. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure resistant Teflon gasket to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-pressure resistant Teflon gasket, comprising a gasket body, wherein a pressure-resistant structure is provided in the gasket body, the pressure-resistant structure includes a pressure-resistant pad, the pressure-resistant pad is provided in the gasket body, and an extension pad is provided on the pressure-resistant pad.

[0007] Preferably, the compression pad is provided with a slot, the extension pad surface is provided with a clamping plate, and the clamping plate is provided with a clamping head.

[0008] Preferably, the surface of the extension pad is provided with a fiber pad.

[0009] Preferably, the surface of the extension pad is provided with a protrusion that protrudes from the surface of the fiber pad.

[0010] Preferably, the extension pad and the compression pad are provided with through holes.

[0011] Preferably, the pressure-resistant pad is provided with a stop.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Because the pressure-resistant structure is located inside the gasket body, the pressure-resistant pad and the extension pad are supported inside the gasket body. When the gasket body is under pressure during installation, the gasket body and the pressure-resistant structure are compressed together. With the support of the pressure-resistant pad and the extension pad, the pressure resistance of the gasket body is guaranteed, giving the gasket body high pressure resistance. The protrusions and fiber pads allow the gasket body and the pressure-resistant structure to be better integrated, preventing the pressure-resistant structure from shifting or misaligning with the gasket body. At the same time, when the gasket body is under pressure, the gasket body is less likely to stretch outward excessively under the force of the fiber pad and the protrusions.

[0019] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0020] Please see Figure 1 and Figure 2 This utility model provides a high-pressure resistant Teflon gasket, including a gasket body 1, which is a sealing element made of polytetrafluoroethylene (PTFE), commonly known as Teflon, and a pressure-resistant structure 2 is provided in the gasket body 1.

[0021] Please see Figure 2 , Figure 3 and Figure 4 This utility model provides a high-pressure resistant Teflon gasket. The pressure-resistant structure 2 includes a pressure-resistant pad 21, an extension pad 22 is provided on the pressure-resistant pad 21, and a slot 23 is provided on the pressure-resistant pad 21. A retaining plate 24 is integrally formed on the surface of the extension pad 22, and a retaining head 25 is integrally formed on the retaining plate 23. The retaining head 25 is engaged with the slot 23 to enable the extension pad 22 to be easily fixed on the pressure-resistant pad 21 for easy installation. Both the extension pad 22 and the pressure-resistant pad 21 are located inside the gasket body 1.

[0022] The extension pad 22 has a fiber pad 26 on its surface and a protrusion 27 on its surface. The protrusion 27 protrudes from the surface of the fiber pad 26 to achieve a better combination between the pad body 1 and the pressure-resistant structure 2, and to prevent the pressure-resistant structure 2 and the pad body 1 from shifting or misaligning. At the same time, when the pad body 1 is compressed, the pad body 1 will not be easily stretched outward due to the action of the fiber pad 26 and the protrusion 27.

[0023] The extension pad 22 and the pressure-resistant pad 21 are provided with through holes 28, and the pad body 1 flows into the through holes 28, making the connection between the pressure-resistant structure 2 and the pad body 1 more stable.

[0024] Among them, the pressure pad 21 is provided with a stop 29 to support the card plate 24, so that the connection between the card head 25 and the card slot 23 is more stable.

[0025] Specifically, since the pressure-resistant structure 2 is located inside the gasket body 1, the pressure-resistant pad 21 and the extension pad 22 will be supported inside the gasket body 1. When the gasket body 1 is installed under pressure, the gasket body 1 and the pressure-resistant structure 2 are compressed together. With the support of the pressure-resistant pad 21 and the extension pad 22, the pressure resistance of the gasket body 1 can be guaranteed, so that the gasket body 1 has high pressure resistance.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
