Description
Technical Field
The invention belongs to the technical field of automobile parts, and particularly relates to an oil-gas separation valve for an automobile.
Background
With the advance of society and the rapid development of automobile industry, the living standard of people is continuously improved, and automobiles become one of important transportation means for people to ride instead of walk. The engine is the heart of an automobile, the part for installing the crankshaft at the lower part of the engine cylinder body of the automobile is called a crankcase, the crankcase is divided into an upper crankcase and a lower crankcase, the upper crankcase and the cylinder body are cast into a whole structure, and the lower crankcase is used for storing lubricating oil and closing the upper crankcase.
When the engine works, part of combustible mixed gas and waste gas always flow into the crankcase through the piston ring, gasoline steam flowing into the crankcase is condensed to thin engine oil and deteriorate the performance, the waste gas contains water vapor and sulfur disulfide, the water vapor is condensed in the engine oil to form foam, the supply of the engine oil is damaged, the sulfur dioxide generates sulfurous acid when meeting water, the sulfurous acid generates sulfuric acid when meeting oxygen in the air, and the acidic substances not only deteriorate the engine oil, but also corrode parts; because the combustible mixed gas and the waste gas are blown into the crankcase, the pressure in the crankcase is increased, the engine oil can seep out from the crankshaft oil seal, the crankcase gasket and the like to be lost, and the engine oil vapor which is lost into the atmosphere can increase the pollution of the engine to the atmosphere; therefore, an oil-gas separation system is required to separate oil from gas in blow-by gas, and a check valve is usually arranged between the oil-gas separator and the gas inlet pipe and is used for guiding the oil gas separated by the oil-gas separator into the gas inlet passage, mixing the oil gas with fresh mixed gas in the gas inlet passage for re-combustion and preventing the phenomenon that the engine does not work or the fresh mixed gas in the small-load gas inlet pipe flows backwards.
In the existing oil-gas separation system, the valve core of the one-way valve is generally not smooth in movement, so that oil gas cannot smoothly flow into an air inlet channel, the situation that fresh mixed gas in the air inlet channel flows backwards when an engine is in a small load or does not work is caused, the ventilation of a crankcase is influenced due to the unsmooth movement of the valve core of the one-way valve, the pressure in the crankcase is too high due to long-term operation of the engine, the phenomena of gas leakage and oil leakage of joints are easy to generate, and meanwhile, the power of the engine is increased, so that the.
