Model utility content
The deficiency existing for prior art, the purpose of this utility model is the seal ring that a kind of good sealing effect is provided and can accurately installs.
For achieving the above object, the utility model provides following technological scheme: a kind of seal ring, comprise body and the stuffing that is located at body interior, the axial seal face of described body is provided with at least two annular convex ribs, the cross section semicircular in shape of described annular convex rib, between described annular convex rib, form oil storage tank, the radial sealing surfaces of described body is provided with annular sealing positioning bar.
By adopting technique scheme, on the axial seal face of seal ring, be provided with semicircle annular convex tendon, make formation between annular convex rib prevent the oil storage tank that sealing medium is revealed, in the radial sealing surfaces of seal ring, be provided with annular sealing positioning bar, make seal ring and the mounting hole by Sealing form interference fit, guarantee that seal ring is in place, effective enhanced leaktightness effect, and guarantee that seal ring is in place.
The utility model is further set to: described body interior is fixedly installed elastic component, and described elastic component is step-like.
By adopting technique scheme, utilize the flexible of elastic component, and the shape setting of elastic component is to step-like, increase the flexible of elastic component, even if seal ring is out of shape also by compression, can recover elasticity at once, thereby move back and forth, and elastic component has elasticity, strengthen the elasticity of seal ring, thereby strengthened its sealing effect, greatly improved sealability.
The utility model is further set to: described body consists of nitinol.
By adopting technique scheme, nitinol is a kind of marmem, marmem is the plastic deformation of self automatically to be reverted under a certain specified temp to the special alloy of original-shape, and the advantages such as that nitinol also has is wear-resistant, anticorrosive, high damping and superelasticity, adopt seal ring that nitinol is made also to there is the performances such as wear-resistant, anticorrosive, high damping and superelasticity, greatly strengthened the sealing effect of seal ring.
The utility model is further set to: the material of described elastic component is stainless steel or titanium alloy.
By adopting technique scheme, the material of elastic component is stainless steel, and due to features such as stainless steel have high mechanical properties, corrosion resistance, the elastic component of therefore being made by stainless steel also has the features such as high mechanical properties and corrosion resistance; Titanium is a kind of important structural metal, because having, intensity is high, corrosion resistance good, heat resistance high is widely used in every field for titanium alloy, the elastic component that adopts titanium alloy to make also has the performances such as intensity is high, corrosion resistance good, heat resistance is high, greatly strengthen mechanical strength and the working life of elastic component, thereby strengthened the elasticity enhancing sealing effect of seal ring.
The utility model is further set to: described external surface is coated with Si Taili cemented carbide.
By adopting technique scheme; Si Taili cemented carbide has good wear resistance and corrosion resistance; at this external surface, spray or be coated with Si Taili cemented carbide; when seal ring carries out seal action; Si Taili hard alloy layer can well protect body not to be subject to the corrosion of extraneous fluid or oxygen, has extended the working life of seal ring.
The utlity model has following advantage: on the axial seal face of seal ring, be provided with semicircular annular convex rib, and between annular convex rib, form the oil storage tank that prevents that sealing medium from revealing, in the radial sealing surfaces of seal ring, be provided with annular sealing positioning bar, make seal ring and the mounting hole by Sealing form interference fit, guarantee that seal ring is in place, effective enhanced leaktightness effect, and guarantee that seal ring is in place.
