The oil seal   is one of the important parts of the engine valve set, and   the valve oil seal of the car  is generally replaced once every 20,000 to 30,000 kilometers, how much do you know about the valve oil seal? Please follow   Honglei   to learn more about the valve oil seal! What is a valve oil seal?   Valve oil seal  is a kind of oil seal, generally by the outer skeleton and fluorine rubber vulcanized together, oil seal diameter mouth installed with a self-tightening spring or steel wire, for the engine valve guide rod seal. Valve oil seal can prevent the oil from entering the intake and exhaust pipe, causing oil loss, preventing the gasoline and air mixture and exhaust gas leakage, and preventing the 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 temperature, so it is necessary to use materials with excellent heat and oil resistance, usually made of fluo

The combination seal  must be composed of two or more independent but correspondingly complementary components. According to the structure and role characteristics of the combination seal, it is divided into one-way seal, two-way seal. What are the sealing principles and characteristics of these combination seals? Please follow   Honglei   to understand!   COMBI F6 58*80*16.5 for Tractor DANA 000051719   Sealing principle   Combined sealing device  (seal) principle is: make full use of the seal material has a separate excellent performance and components of the most reasonable structural form, made of independent components, two independent components of the organic combination, one of the components mainly play a sealing role, while the other component i mainly play the role of force; Glei ring combination seal in the Glei ring to play a sealing role, while the O-ring compression deformation of the elastic force applied to the Glei ring, so that the Glei ring tight seal. to make the G
