Abstract
The utility model discloses a valve oil seal with an air sealing lip structure, which comprises a tubular framework. The cross section of the tubular framework is in an inversed L shape and is bent upwards. A rubber layer vulcanized into a whole with the framework is covered on the top end and the inner wall of the framework. A main annular lip opening is arranged on the inner side of the top end of the rubber layer, a spring groove is installed on the outer side of the top end of the rubber layer, and a clamping spring is assembled inside the spring groove. An annular air sealing lip opening is arranged on the inner side of the rubber layer positioned at the bent section of the framework, and the inner side of the annular air sealing lip opening is in a convex shape. The valve oil seal with the air sealing lip structure optimizes the design of the support framework, and keeps a main lip to be contacted with a valve rod under certain pressure, thereby guaranteeing the control function of the valve oil seal to engine oil leakage rate.
Description
Technical field
The utility model relates to a kind of oil sealing, mainly is a kind of valve oil seal with envelope gas procheilon structure.
Background technique
At present, traditional valve oil seal all is only single main procheilon structure, though it can satisfy the requirement of control valve stem lubricating oil leakage rate under conventional operating mode, but when particular application has certain pressure, when main lip is opened under pressure, the afunction of valve oil seal control lip leak-down rate.
The model utility content
The technical problems to be solved in the utility model provides a kind of valve oil seal with envelope gas procheilon structure, it has optimized the support frame design, guarantee under the certain pressure occasion, keep contacting of main lip and valve stem, thereby guarantee the control function of valve oil seal the lubricating oil leakage rate.
For addressing the above problem, the technical solution adopted in the utility model is:
A kind of valve oil seal with envelope gas procheilon structure includes cylindrical skeleton, and the cross section of described cylindrical skeleton is down L shaped and upwards bending, is coated with on the top of described skeleton and the inwall and its sulfuration all-in-one-piece rubber layer; There is annular lip the inboard on described rubber layer top, the outside on described rubber layer top has spring groove, be equipped with the lock ring spring in the spring groove, there is an envelope gas ring shape lip the described inboard that is positioned at the rubber layer of skeleton bend section, and described envelope gas ring shape lip inboard is convex.
The spring groove in the main loop lip of described rubber layer inboard and the rubber layer outside is at same horizontal position.
The skeleton and the vulcanization of rubber are as inwall assembling support or static seal effect in the utility model, and the lock ring spring is installed in the spring groove of main loop lip one horizontal position, and the maintenance lip is assembled to the power of holding tightly after axle is gone up.The skeleton optimal design improves main lip-openable pressure, seal in addition gas lip design when the main loop lip is opened, keep envelope gas lip with spool contact, avoid ambient atmos to enter the firing chamber, thereby influence engine combustion performance and overall performance.
The utility model has the advantages that:
The utility model has adopted envelope gas procheilon structure, and optimized frame design, guarantee under the certain pressure occasion, keep main loop lip, envelope gas ring shape lip to contact with valve stem, thereby guarantee the control function of valve oil seal to the lubricating oil leakage rate, and after the main loop lip was opened, envelope gas lip prevented that gas from entering the firing chamber and influencing engine performance, is applicable to the occasion that possesses certain working pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, a kind of valve oil seal with envelope gas procheilon structure includes cylindrical skeleton 1, and the cross section of described cylindrical skeleton 1 is down L shaped and upwards bends 2, is coated with on the top of described skeleton 1 and the inwall and its sulfuration all-in-one-piece rubber layer 3; There is annular lip 4 inboard on described rubber layer 3 tops, the outside on described rubber layer 3 tops has spring groove, be equipped with lock ring spring 5 in the spring groove, there is an envelope gas ring shape lip 6 the described inboard that is positioned at the rubber layer 3 of skeleton bend section 2, and described envelope gas ring shape lip 6 inboards are convex.
