Description
Technical field
The utility model relates to a kind of seal element, and in particular, it relates to a kind of seal ring.
Background technique
Seal ring is a kind of modal seal element in machine-building and flight-line maintenance field, current seal ring size is fixed, unadjustable, can only for seal diameter size suitable by the sealing of Sealing, if this size by Sealing differs, when this is installed by Sealing, need to change seal ring, operation is trouble very, and the using scope of seal ring is little.Therefore, be necessary seal ring to improve.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of seal ring of adjustable dimension, sealing circle can be used for different size size by Sealing, using scope is wide.
For achieving the above object, the utility model provides following technological scheme: a kind of seal ring, comprise body, described body comprises the fixing part of hollow, on described fixing part, be at least provided with a Collapsible structure, described Collapsible structure comprise be all located in fixing part and one end protrude fixing part head rod and the second connecting rod, described head rod and the second connecting rod are slidably matched, described the second connecting rod is provided with elastic component, and described head rod is provided with some through holes that wear for elastic component.
By adopting technique scheme, when seal ring is installed, head rod is located in fixing part, then the second connecting rod was also worn to the opposite side of fixing part, head rod and the second connecting rod are all fitted on fixing part inwall and can carry out slippage cooperation, when larger by the size of Sealing, head rod and the second connecting rod can be pulled out to fixing part, make head rod with the second connecting rod all towards moving relative to fixing part opposite side, head rod is socketed on the second connecting rod and is slidably matched, elastic component on the second connecting rod is compressed between head rod and the second connecting rod until elastic component wore the through hole of head rod, head rod and the second connecting rod are fixed, when if the size that occurs seal ring is still too small, elastic component is separated with this through hole, head rod and the second connecting rod continue mobile until elastic component wore next through hole, this Collapsible structure regulates seal ring size, can be used for different size size by Sealing, using scope is wide.
The utility model is further set to: described head rod one end is located in fixing part and the other end is socketed on the second connecting rod.
By adopting technique scheme, head rod be socketed on the second connecting rod and head rod and the second connecting rod between can be slidably matched, when head rod and the second connecting rod relatively move, Collapsible structure shortens, when head rod and the second connecting rod move in opposite directions, Collapsible structure is elongated, realizes the telescopicing performance of Collapsible structure.
The utility model is further set to: between described fixing part upper-end surface inwall and fixing part lower end surface inwall, be fixedly installed spring, described spring is axially disposed within fixing part.
By adopting technique scheme, utilize the flexible of spring, even if seal ring is out of shape also by compression, can recover elasticity at once, when seal ring be placed in two by Sealing between time, after being axially disposed within spring in fixing part and being squeezed there is deformation in compression, after removing by Sealing, spring recovers elastic potential energy and elastic potential energy is converted to kinetic energy, thereby moves back and forth, and spring has elasticity, strengthen the elasticity of seal ring, thereby strengthened its sealing effect, greatly improved sealability.
The utility model is further set to: the making material of described fixing part, head rod and the second connecting rod is 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 nitinol also has the advantages such as wear-resistant, anticorrosive and superelasticity, the fixing part, head rod and the second connecting rod that adopt nitinol to make also have the performances such as wear-resistant, anticorrosive and superelasticity, have greatly strengthened the sealing effect of seal ring.
The utility model is further set to: the outer surface of described fixing part, head rod and the second connecting rod is all coated with Si Taili cemented carbide.
By adopting technique scheme; Si Taili cemented carbide has good wear resistance and corrosion resistance; outer surface at fixing part, head rod and the second connecting rod all sprays or electroplates officials Tai Li 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: be provided with the Collapsible structure that regulates seal ring size, can be used for different size size by Sealing, using scope is wide.
