Abstract
The utility model discloses a seal ring, comprising a body, wherein an annular groove penetrating the whole inner wall circumference is formed in the inner wall of the body; a spring adaptive to the annular spring is arranged on the annular groove; one side of the spring is welded with the inner wall of the annular groove. The annular groove used for fixedly containing the spring is formed in the inner wall of the body, one side, opposite to the annular groove, of the spring is occlusal with threads on a fastening piece, a sealing effect is achieved by the sealing ring, and a fixing effect is also achieved between the sealing ring and the fastening piece.
Description
Technical field
The utility model relates to a kind of seal ring.
Background technique
The existing seal ring for pipeline equipment end face seal is generally single rubber material or other macromolecular materials, the seal ring of this structure is when for the higher occasion of relatively large equipment and some temperature, pressure, its sealing effect is difficult for guaranteeing, and seal ring is not fixedly connected with when fastening piece in pipe fitting is connected, just contact, easily rock, its material is also easily because aging distortion is followed the string, thereby working life is shorter, need frequent replacing, affect the operational efficiency of equipment.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of good sealing effect, can be fixedly connected with fastening piece and the seal ring of long service life.
For achieving the above object, the utility model provides following technological scheme: a kind of seal ring, comprise body, described inner body wall is provided with the annular groove that runs through whole inwall circumference, described annular groove is provided with the spring suitable with annular groove, described spring one side and the welding of annular groove inwall.
By adopting technique scheme, in inner body wall, offer the annular groove for spring fixed placement, crooked wire in relative annular groove one side of spring and the threaded engagement on fastening piece, be fixed on screw thread, make seal ring not only play sealing effect, but also play the fixation between seal ring and fastening piece.
The utility model is further set to: on described body outer wall and inwall, all scribble resin layer.
By adopting technique scheme, in body outer wall surface and inner wall surface, all scribble resin layer, even if be full of under the environment that water, air etc. easily get rusty, seal ring still can work, the setting up the working life that can extend seal ring of resin layer.
The utility model is further set to: the material of described spring is stainless steel or titanium alloy.
By adopting technique scheme, the material of spring is stainless steel, and due to features such as stainless steel have high mechanical properties, corrosion resistance, the spring 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 spring that adopts titanium alloy to make also has the performances such as intensity is high, corrosion resistance good, heat resistance is high, has greatly strengthened the mechanical strength of spring.
The utility model is further set to: the material of described body 1 is titanium alloy.
By adopting technique scheme, titanium is a kind of important structural metal, and because having, intensity is high, corrosion resistance good, heat resistance high is widely used in every field for titanium alloy; The seal ring that adopts titanium alloy to make also has the performances such as intensity is high, corrosion resistance good, heat resistance is high, has greatly strengthened the mechanical strength of seal ring.
The utility model is further set to: described resin layer is 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: in inner body wall, offer the annular groove for spring fixed placement, make the threaded engagement on relative annular groove one side of spring and fastening piece, seal ring not only plays sealing effect, but also plays the fixation between seal ring and fastening piece.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model seal ring.
In figure: 1, body; 2, annular groove; 3, spring.
Embodiment
Shown in Fig. 1, the seal ring of the present embodiment, comprises body 1, and described body 1 inwall is provided with the annular groove 2 that runs through whole inwall circumference, described annular groove 2 is provided with the spring 3 suitable with annular groove 2, described spring 3 one sides and annular groove 2 inwall welding.
By adopting technique scheme, on body 1 inwall, offer the annular groove 2 for spring 3 fixed placement, crooked wire in relative annular groove 2 one sides of spring 3 and the threaded engagement on fastening piece, be fixed on screw thread, make seal ring not only play sealing effect, but also play the fixation between seal ring and fastening piece.
On described body 1 outer wall and inwall, all scribble resin layer, in body 1 outer wall surface and inner wall surface, all scribble resin layer, even if be full of under the environment that water, air etc. easily get rusty, seal ring still can work, the setting up the working life that can extend seal ring of resin layer.
The material of described spring 3 is stainless steel or titanium alloy, and the material of spring 3 is stainless steel, and due to features such as stainless steel have high mechanical properties, corrosion resistance, the spring 3 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 spring 3 that adopts titanium alloy to make also has the performances such as intensity is high, corrosion resistance good, heat resistance is high, has greatly strengthened the mechanical strength of spring 3.
The material of described body 1 is titanium alloy, and titanium is a kind of important structural metal, and because having, intensity is high, corrosion resistance good, heat resistance high is widely used in every field for titanium alloy; The seal ring that adopts titanium alloy to make also has the performances such as intensity is high, corrosion resistance good, heat resistance is high, has greatly strengthened the mechanical strength of seal ring.
Described resin layer is Si Taili cemented carbide; Si Taili cemented carbide has good wear resistance and corrosion resistance; at body 1 outer 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 1 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 body 1 inwall, offer the annular groove 2 for spring 3 fixed placement, make the threaded engagement on relative annular groove 2 one sides of spring 3 and fastening piece, seal ring not only plays sealing effect, but also plays the fixation between seal ring and fastening piece.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technological schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
