Valve oil seal is a kind of oil seal, generally by the outer skeleton and fluorine rubber jointly vulcanized, oil seal diameter mouth is installed with a self-tightening spring or steel wire, for the sealing of the engine valve guide rod.
The valve oil seal can prevent the oil from entering the intake and exhaust pipes, avoid oil loss, prevent gasoline and air mixtures and emission gas leakage, and prevent engine oil from entering the combustion chamber. The valve oil seal is one of the important parts of the engine valve set, which is in contact with gasoline and oil at high temperatures, so it is necessary to use materials with excellent heat resistance and oil resistance, generally made of fluoroelastomer
Valve stem seals prevent oil from contaminating the air/fuel mixture in the engine’s combustion chamber. They also prevent intake and exhaust gases from contaminating the oil in the cylinder head and the rest of the engine. Valve stem seams are like any other round seal, only much smaller. The inside diameter fits over the valve stem.
Why your valve oil seal is aging?
If your car is slow to accelerate or the car is emitting blue smoke, then your valve oil seal is already aging. So what is the cause of this series of problems?
The first is the problem of valve oil seal installation: for example, mixing in during installation, or foreign matter in the pipeline, dust, entering the seal and causing leakage; Poor assembly caused by seal damage caused by leakage; The wrong direction of the seal installation leads to leakage or because the coating is processed unevenly, and the paint enters the sealing layer.
The second is the selection of the seal: the gap bite caused by excessive pressure, and then mixed with the air, the adiabatic compression causes the seal to burn; High-frequency reciprocating movement causes the seal to heat up and dry grind; Environmental dust causes abnormal wear of the sealing ring; Rusting of the sealing groove causes leakage and other problems.
The third is the design of sealing equipment. This includes
1. The improper selection of the material of the guide support parts damages the cylinder barrel and piston rod
2. The friction pair gap is not suitable, resulting in the gap extrusion bite
3. The thread guide angle of the cylinder barrel piston cylinder end is improper, and the sealing ring is damaged
4. Improper sealing and installation of the guide angle damages the sealing ring
5. The roughness of the sliding surface is not suitable and the sealing ring is worn
6. The electroplating is uneven, and the surface through which the seal passes is cut and the sealing ring is scratched
7. The roughness of the sealing groove, especially the shaft sealing groove, is not enough, and the wear damages the seal
Finally, it may be the problem of the product itself, or the problem of sealing and storage, which is subject to high temperature during transportation, causing the sealing material to deteriorate and deteriorate.
