Abstract
The utility model relates to the technical field of sealing, in particular to an oil seal of a fluororubber valve rod. The oil seal of the fluororubber valve rod comprises a skeleton, a rubber body and a polytetrafluoroethylene (PTFE) sealing body, wherein the rubber body is arranged on the skeleton; a sealing lip is arranged on the inner side of the PTFE sealing body; and the skeleton is inserted at the lower end of the PTFE sealing body. The skeleton of the oil seal of the fluororubber valve rod is designed on the basis of pure rubber so as to greatly facilitate the assembling of the valve rod oil seal, ensure the assembling and positioning of the seal, avoid the escape or leakage of lubricating oil of an automobile lubricating system, guarantee the sealing effect, prolong the service life of the valve rod oil seal, and meet the using requirement.
Description
Technical field
The utility model relates to technical field of sealing technology, especially a kind of fluorine rubber stem oil seal.
Background technique
Seal ring is installed in vehicle lubricating system, traditional seal ring is generally single rubber material or other macromolecular materials, when the seal ring of this structure is the housing pairing, its sealing effect is difficult for guaranteeing, its material also follows the string because of aging distortion easily, thereby working life is shorter, needs frequent, affects the operational efficiency of equipment.In addition, because sealing effect is undesirable, the lubricant medium of lubrication system is leaked or seepage, can not satisfy user demand, serious entail dangers to personal safety.
The model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of easy for installation, the fluorine rubber stem oil seal of good sealing effect.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of fluorine rubber stem oil seal, comprise skeleton, be arranged on rubber body and PTFE seal on the skeleton, PTFE seal inner side surface is provided with sealing lip, and described skeleton is plugged on the lower end of PTFE seal.
Further, the outer of the corresponding sealing lip of described PTFE seal is provided with spring ring, can play the banding effect.
Further, described rubber body adopts fluorine rubber, the characteristic that fluorine rubber has is high temperature resistant, oil resistant and the medicine of anti-the number of chemical corrode, better tightness, long service life.
The beneficial effects of the utility model are, fluorine rubber stem oil seal of the present utility model design framework on the basis of gum, greatly facilitate the installation of stem oil seal, guaranteed better the assembling and positioning of sealing, avoid the lubricant oil of vehicle lubricating system to leak or seepage, guarantee sealing effect, in the working life of having improved stem oil seal, satisfy usage requirement.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. skeletons among the figure, 2. rubber body, 3.PTFE seal, 4. sealing lip.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Fluorine rubber stem oil seal as shown in Figure 1 comprises skeleton 1, is arranged on rubber body 2 and PTFE seal 3 on the skeleton 1, and PTFE seal 3 inner side surfaces are provided with sealing lip 4, and skeleton 1 is plugged on the lower end of PTFE seal 3.The outer of PTFE seal 3 corresponding sealing lips 4 is provided with spring ring, can play the banding effect.Rubber body 2 adopts fluorine rubber, the characteristic that fluorine rubber has is high temperature resistant, oil resistant and the medicine of anti-the number of chemical corrode, better tightness, long service life.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
