Abstract
The utility model relates to the technical field of sealing elements, in particular to a valve oil seal, which comprises a skeleton and a rubber sealing body covering one end of the skeleton, wherein a convex edge is arranged on a contact surface between the skeleton and the rubber sealing body; and an inclined plane is arranged between the rubber sealing body and the convex edge. According to the valve oil seal, the skeleton is designed on basis of the pure rubber, which brings great convenience to the mounting of the sealing ring, better ensures the sealing assembling location, avoids external leakage or seepage of lubricating oil of a rice transplanter lubricating system, ensures the sealing effect, and further prevents mug and meets the use requirement.
Description
Technical field
The utility model relates to the Sealing technical field, especially a kind of valve oil seal.
Background technique
Valve oil seal is used for the sealing to the engine valve guide rod, prevents that lubricant oil from entering the 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, 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 thermal diffusivity good valve oil seal, guaranteed the normal operation of valve and the service behaviour of motor.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of valve oil seal, comprise skeleton and the rubbery sealed body that is coated on skeleton one end, described skeleton and rubber seal contact level have the convex edge, the convenient location of installing, when valve guide rod carries out to-and-fro motion at a high speed and rotatablely moves, avoid valve oil seal to rotate together, in addition, have the plane of inclination between described rubbery sealed body and the convex edge, effectively prevent oil leakage.
Further, described skeleton adopts fluorine rubber for the iron-clad through antirust processing, described rubbery sealed body, so that strengthen again its thermal diffusivity when improving sealability.
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, satisfy usage requirement.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is generalized section of the present utility model.
1. skeletons among the figure, 1-1. convex edge, 2. rubbery sealed body.
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 skeleton 1 and the rubbery sealed body 2 that is coated on skeleton 1 one ends, skeleton 1 has convex edge 1-1 with rubbery sealed body 2 surface of contact, the convenient location of installing, when valve guide rod carries out to-and-fro motion at a high speed and rotatablely moves, avoid valve oil seal to rotate together.Secondly, have the plane of inclination between rubbery sealed body 2 and the convex edge 1-1, effectively prevent oil leakage.In addition, skeleton 1 is the iron-clad through antirust processing, and rubbery sealed body 2 adopts fluorine rubber, and the valve oil seal of this design is so that strengthen again its thermal diffusivity when improving sealability.
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.
Claims (2)
