The utility model is set to further: described spring side is welded with arc groove inwall.
By adopting technique scheme, corresponding arc groove one side of spring is welded on arc groove inwall, prevent spring from departing from arc groove, enhance the connectivity robustness between spring and arc groove, because spring has elasticity, the elasticity being wrapped in the first link on spring and the second link all strengthens, and while the elasticity of metal o-ring is strengthened, its structural strength is also enhanced.
The utility model is set to further: be installed with spring between described first link upper-end surface inwall and the first link lower end surface inwall, also be installed with spring between described second link upper-end surface inwall and the second link lower end surface inwall, described spring is all axially disposed within the first link and the second link.
By adopting technique scheme, utilize the flexibility of spring, even if make metal o-ring be out of shape by compression also can recover elasticity at once, when metal o-ring be placed in two by Sealing between time, after the spring be axially disposed within respectively in the first link and the second link is squeezed there is deformation in compression, when removing after by Sealing, spring recovers elastic potential energy and elastic potential energy is converted to kinetic energy, thus move back and forth, and spring has elasticity, enhance the elasticity of metal o-ring, thus strengthen its sealing effect, greatly improve sealability.
The utility model is set to further: the making material of described first link and the second link is nitinol.
By adopting technique scheme, nitinol is a kind of marmem, marmem is the special alloy that the plastic deformation of self can be automatically restored under a certain specified temp original-shape, and nitinol also has the advantages such as wear-resistant, anticorrosive and superelasticity, the first link adopting nitinol to make and the second link also have the performances such as wear-resistant, anticorrosive and superelasticity, greatly strengthen the sealing effect of metal o-ring.
The utility model is set to further: the outer surface of described first link and the second link is all coated with Si Taili cemented carbide.
By adopting technique scheme; Si Taili cemented carbide has good wear resistance and corrosion resistance; all spray or electroplate officials Tai Li cemented carbide at the outer surface of the first link and the second link; when metal o-ring carries out seal action; Si Taili hard alloy layer can well protect body not to be subject to the corrosion of external fluid or oxygen, extends the working life of metal o-ring.
The utility model has following advantage: can be for convenience detach, when this metal o-ring damages, as long as change the part damaged, saving resource, improves the utilization ratio of metal o-ring.
