Abstract
The utility model relates to a sandwich gasket seal, aiming at further improving the performance of the gasket seal. The polytetrafluoroethylene sandwich gasket seal with metal wrapping die and metal high strength graphite is a slice in a shape of ring, consisting of an outer layer( surface layer) and an inner layer(sandwich layer in the middle). The surface layer is polytetrafluoroethylene one, while the inner layer consists of soft graphite plates and metal plates for punching holes. The utility model is characterized in that the metal plate is arranged in the middle of the gasket seal layer and the soft graphite plate which has a symmetric structure centering on the gasket seal layer is provided with at least one layer. The outer edge of the middle sandwich layer is provided with metal wrapping die. The utility model can be applied to the interface of various liquid or gas tube valve.
Description
Technical field
The utility model relates to the gasket seal that flange-interface places such as pipeline use, and also claims seal washer, refers in particular to a kind of graphite interlayer gasket seal, or graphite interlayer seal washer.
Background technique
Existing teflon graphite interlayer gasket seal, intermediate filler layer is a multi-layer structure, include flexible graphite plate, metal spurt plate etc., through on-the-spot use for many years, still find to exist some deficiency, for example relatively poor to the protective value of Expanded graphite layer, shock strength is not enough, and the anti-damage intensity on surface, gasket seal outer ring is lower, particularly the narrow heavy caliber pad in limit, the usability instability, very easily decrease ring: in the occasion that is used to have the pump vibrations, pipeline on the boats and ships, submarine pipelines etc. often have under the situation of sea beat etc., use gasket seal therebetween very easily to damage, as produce crack even burst apart etc., cause the medium evaporating, emitting, dripping or leaking of liquid or gas in the pipeline; And the generation of this type of thing is one of major reason about the service property (quality) and the life-span quality of gasket seal often, and the performance of existing these gasket seals is still not ideal enough in a word.
Summary of the invention
The purpose of this utility model provides a kind of metal bound edge teflon high-strength graphite interlayer gasket seal with high strength, long lifetime, dominance energy.
The purpose of the utility model performance is achieved in that metal bound edge teflon high-strength graphite interlayer gasket seal, it is the round thin slice, by skin is that surface layer and internal layer are that intermediate course is formed, surface layer is a polytetrafluoroethylene floor, intermediate course is that the sheet metal in flexible graphite plate and spurt or hole is formed, it is characterized in that: sheet metal is positioned at the centre of sealing gasket lamella, and outwards is the symmetry properties structure with it; Flexible graphite plate is at least more than one deck, and the outer circumference of intermediate course is provided with the metal bound edge.
Above-mentioned design, being positioned at backbone that sheet metal in the middle of the whole sealing gasket lamella constitutes gasket seal becomes and has high-intensity skeleton, and the whole outer circumference of the intermediate course of gasket seal closely, firmly, high duty metal sheet package is arranged, but also can help utilizing regenerated resources, reduce environmental pollution.The gasket seal of this project organization has reached the good result that intensity is higher, the life-span is longer, performance is more excellent according to test.
