Description

Teflon gasket resistant to high pressure Technical Field The utility model relates to the technical field of Teflon gaskets, in particular to a high-pressure-resistant Teflon gasket. Background The Teflon gasket is a sealing element made of polytetrafluoroethylene (PTFE, commonly known as Teflon), has excellent chemical resistance, high temperature resistance, low friction coefficient and insulating property, and is widely applied to the fields of industry, chemical industry, food, medicine and the like. The existing teflon gaskets have the following problems: The compression resistance of the Teflon gasket is a key consideration in the application of the Teflon gasket, but the existing Teflon gasket has poor compression resistance, is easy to generate plastic deformation under continuous pressure, and causes the problem of sealing failure. Disclosure of utility model The utility model aims to provide a high-pressure-resistant Teflon gasket so as to solve the problems in the background technology. In order to achieve the purpose, the high-pressure-resistant Teflon gasket comprises a gasket body, wherein a compression-resistant structure is arranged in the gasket body and comprises a compression-resistant pad, the compression-resistant pad is arranged in the gasket body, and an extension pad is arranged on the compression-resistant pad. Preferably, the pressure-resistant pad is provided with a bayonet, the surface of the extension pad is provided with a clamping plate, and the clamping plate is provided with a clamping head. Preferably, the surface of the extension pad is provided with a fibrous pad. Preferably, the surface of the extension pad is provided with a protruding part, and the protruding part protrudes from the surface of the fiber pad. Preferably, through holes are arranged in the extension pad and the pressure-resistant pad. Preferably, a stop block is arranged on the pressure-resistant pad. Compared with the prior art, the utility model has the beneficial effects that: Because compressive structure is located inside the gasket body, so compressive cushion and extension pad can support inside the gasket body, when the gasket body is installed and pressed, gasket body and compressive structure are pressed together, under the support of compressive cushion and extension pad, the compressive capacity of gasket body can be guaranteed for the gasket body has high-pressure resistance, bellying and fibre pad can make gasket body and the better combination of compressive structure, avoid compressive structure and gasket body to take place the skew dislocation, simultaneously when gasket body is pressed, the gasket body can be under the effect of fibre pad and bellying, the outward excessive extension of difficult atress of gasket body.
