More Information
Summary:The utility model relates to a wear resistant long-term seal, which comprises two parts of a Teflon layer (1) and aramid fiber layers (2), wherein the aramid fiber layers (2) are positioned at positions at four corners of the Teflon layer (1) in the circumferential direction; contact surfaces between the Teflon layer (1) and the aramid fiber layers (2) are all saw-toothed so as to allow the aramid fiber layers (2) to be embedded in the Teflon layer (1). According to the wear resistant long-term seal, the aramid fiber layers are inserted in the Teflon layer, so that the wearing resistance of the seal is greatly increased; therefore, the service life of the seal is prolonged.
