Technical Field
The utility model relates to a mounting structure of check valve, concretely relates to oil cleaner's check valve mounting structure.
Background
When the engine works, metal abrasive dust generated on the friction surface of the part, dust in the atmosphere and carbon particles generated by incomplete combustion of fuel can permeate into engine oil, the engine oil is heated and oxidized to generate colloidal precipitates, and the impurities can be mixed in the engine oil. If such dirty oil is directly supplied to the surface of a moving part, mechanical impurities in the oil become abrasive materials, which accelerate wear of the part and cause clogging of an oil passage and cementation of parts such as piston rings, valves, etc. Therefore, an oil filter must be provided in the lubricating system to purify the circulating oil before it is sent to the surface of the moving parts. Ensuring good lubrication of the friction surface and prolonging the service life of the friction surface.
The check valve is an important component in the oil filter, and functions to prevent oil from flowing back and flowing out from the oil inlet. The valve body of the existing check valve is generally arranged in a horn shape and is reversely buckled on a chassis of the filter during installation, but because the inner side surface of the horn-shaped check valve body is of a straight inclined surface structure, the elasticity is small, the sealing performance is weak, the opening resistance is large after the horn-shaped check valve body is attached to the chassis, and a large amount of oil leakage can occur due to the fact that the horn-shaped check valve body cannot be influenced by pressure after being used for a period of time, so that improvement is needed.
