Abstract
The utility model relates to the technical field of automobile accessories, in particular to an engine valve oil seal which comprises a framework, a rubber sealing body and a PTFE sealing body. The rubber sealing body and the PTFE sealing body wrap the inner side and the upper end of the framework respectively. A spring ring is arranged on the outer edge of the rubber sealing body, and ripples are arranged on the inner circumferential face of the rubber sealing body. According to the engine valve oil seal, the framework is designed based on pure rubber, installation of the sealing ring is greatly facilitated, sealed assembling locating is better guaranteed, lubrication oil of an engine lubrication system is prevented from leaking or seeping, the sealing effect is guaranteed, and the using requirement is met.
Description
Technical field
The utility model relates to the auto-parts technical field, especially a kind of engine valve oil seal.
Background technique
Engine valve oil seal, for the sealing to the automotive engine valves guide rod, prevents that lubricant oil from entering firing chamber, reduces engine performance.Traditional engine valve oil seal is generally single rubber material or other macromolecular materials, the seal ring of this structure is when matching with housing, its sealing effect is difficult for guaranteeing, radiating effect is poor, its material also easily follows the string because of aging distortion, thereby working life is shorter, need to frequently change, affect the operational efficiency of equipment.In addition, because sealing effect is undesirable, very easily make the lubricant medium of lubrication system leak or seepage, can not meet 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 the engine valve oil seal that a kind of thermal diffusivity is good, guaranteed the normal operation of valve and the service behaviour of motor.
The utility model solves the technological scheme that its technical problem adopts: a kind of engine valve oil seal, comprise skeleton and the rubbery sealed body and the PTFE seal that are coated on skeleton inboard and skeleton upper end, described rubbery sealed body outer is provided with spring ring, the inner peripheral surface of described rubbery sealed body is provided with ripple, has improved the servo-actuated property of oil sealing.
Further, described skeleton, for the iron-clad through antirust processing, described rubbery sealed body adopts fluorine rubber, makes when improving sealability and strengthens again its thermal diffusivity.
The beneficial effects of the utility model are, engine valve oil seal of the present utility model is design framework on the basis of gum, greatly facilitate the installation of seal ring, guaranteed better the assembling and positioning of sealing, avoid the lubricant oil of engine lubrication system to leak or seepage, guarantee sealing effect, meet usage requirement.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is generalized section of the present utility model.
1. skeletons in figure, 2. rubbery sealed body, 3.PTFE seal, 4. spring ring, 5. ripple.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram 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.
Engine valve oil seal as shown in Figure 1, comprise skeleton 1 and the rubbery sealed body 2 and the PTFE seal 3 that are coated on skeleton 1 inboard and skeleton 1 upper end, rubbery sealed body 2 outers are provided with spring ring 4, and the inner peripheral surface of rubbery sealed body 2 is provided with ripple 5, have improved the servo-actuated property of oil sealing.Skeleton 1 is the iron-clad through antirust processing, and rubbery sealed body 2 adopts fluorine rubber, makes when improving sealability and strengthens again its thermal diffusivity.
The above-mentioned foundation desirable embodiment of the present utility model of take is enlightenment, and 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 specification, must determine its technical scope according to the claim scope.
