Abstract
The utility model relates to the technical field of automobile spare parts, in particular to a valve oil seal. The valve oil seal comprises an L-shaped metallic framework and rubber seal bodies which wrap the inner side and the upper end of the L-shaped metallic framework, spring rings are arranged on the outer edges of the rubber seal bodies, and corrugations are arranged on the inner circumferential faces of the rubber seal bodies. According to the valve oil seal, the framework is designed on the basis of pure rubber, the installation of a seal ring is greatly facilitated, sealing positioning is well ensured, lubrication oil of an engine lubrication system is prevented from leaking and seeping, the sealing effect is ensured, and the operating requirement is met.
Description
Technical field
The utility model relates to the auto-parts technical field, especially a kind of valve oil seal.
Background technique
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 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 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 valve oil seal, comprise " L " type metal frame and the rubbery sealed body that is coated on skeleton inboard and skeleton upper end, described rubbery sealed body outer is provided with spring ring, and the inner peripheral surface of described rubbery sealed body is provided with ripple.
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, 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. spring ring, 4. 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.
Valve oil seal as shown in Figure 1, comprise " L " type metal frame 1 and the rubbery sealed body 2 that is coated on skeleton 1 inboard and skeleton 1 upper end, rubbery sealed body 2 outers are provided with spring ring 3, and the inner peripheral surface of rubbery sealed body 2 is provided with ripple 4, 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.
Claims (2)
