By adopting technique scheme, annular groove and lower annular groove on being provided with in metal carbonyl coat, and be respectively equipped with at upper annular groove and lower annular groove convex platform and the lower convex platform of laying for elastic component, strengthen elasticity and the sealing effect of metal o-ring, due to elastic component can return action, metal carbonyl coat is out of shape by compression and plays seal action, improves the access times of metal o-ring, extends the working life of metal o-ring.
The utility model is further set to: described elastic component is spring.
By adopting technique scheme, elastic component is preferably spring, utilize the flexible of spring, even if being out of shape also by compression, metal o-ring can recover elasticity at once, thereby move back and forth, and spring has elasticity, strengthened the elasticity of metal o-ring, thereby strengthen its sealing effect, greatly improve sealability.
The utility model is further set to: the outer surface of described metal carbonyl coat scribbles resin layer, and described resin layer is epoxy coating.
By adopting technique scheme; outer surface at metal carbonyl coat scribbles epoxy coating as resin layer; epoxy coating does not singly have the chemical features such as excellent water-fast, oil resistant is dirty, chemicals-resistant corrosion; and have attachedly exert oneself, mechanical strength is high, wear-resisting function is good, makes protective layer fine and close; adhesion metal is firm; there is good anti-corrosion effect, and do not have environmental pollution, can effectively improve sealability and the working life of metal o-ring.
The utility model is further set to: described convex platform and lower convex platform are symmetrical up and down, described convex platform, lower convex platform all with elastic component clamping.
By adopting technique scheme, it is symmetrical up and down that convex platform and lower convex platform are, and between convex platform and lower convex platform, clamping is provided with elastic component, and elastic component is fixed, the elastic reaction that guarantees elastic component makes metal o-ring have elasticity, performance seal action.
The utility model is further set to: on described metal carbonyl coat, be coated with Si Taili cemented carbide.
By adopting technique scheme; Si Taili cemented carbide has good wear resistance and corrosion resistance; at metal carbonyl coat outer surface, be coated with Si Taili cemented carbide; when metal o-ring carries out seal action; Si Taili hard alloy layer can well protect metal carbonyl coat not to be subject to the corrosion of extraneous fluid or oxygen, has extended the working life of metal o-ring.
The utlity model has following advantage: in metal carbonyl coat, be provided with annular groove and lower annular groove, and be respectively equipped with at upper annular groove and lower annular groove convex platform and the lower convex platform of laying for elastic component, strengthen elasticity and the sealing effect of metal o-ring, improve the access times of metal o-ring, extend the working life of metal o-ring.
