Problems solved by technology
[0003] The air release valve is also suitable for the oil circuit system of the engine. In the existing engine oil circuit system, due to the poor emptying capacity of some oil pumps, there are problems such as starting for the first time, changing the machine filter, or stopping for a long time (oil When restarting after the passage of oil to the oil pan), since the air in the oil passage cannot be removed in time, the oil pressure in the main oil passage of the engine takes too long to build up, and the gas can only be drained from the friction pair and other gaps, resulting in the failure of the friction pair Wait for the lubricating oil to be squeezed away by the air, causing the parts to wear out due to lack of oil and affecting the life of the engine

The invention discloses an oil-resisting gas-discharging valve for an engine. The oil-resisting gas-discharging valve comprises a hollow bolt, a valve core, a spring and a cotter pin, wherein the spring is sleeved on the main body of the valve core; one end of the spring is fixed on a base of the valve core; the main body of the valve core sleeved with the spring is inserted in a bolt main body; a through pin hole is formed on a side wall of the bolt main body; the cotter pin is assembled in the pin hole; a through gas-discharging hole is formed on the base of the valve core; and the oil-resisting gas-discharging valve is mounted behind an oil way of the engine. In a working process, after the pressure of the oil way is formed, gas can be quickly discharged from a gas-discharging channel according to a negative pressure principle; when the valve core meets a large amount of oil, the pressure generated by the spring is overcome by the pressure of the oil; the gas-discharging hole of the valve core is moved till the valve core and the gas-discharging hole are sealed, and the gas-discharging channel is closed by the valve core; and the oil-resisting gas-discharging valve for the engine is characterized by high gas-discharging speed, high oil resisting sensitivity, capability of adjusting the selected spring according to a specific requirement and capability of setting a suitable pressure scope.
Description
technical field [0001] The invention relates to an engine oil circuit system, in particular to an engine oil resistance and air release valve for automatically exhausting the oil circuit system when the engine is started. Background technique [0002] Air release valve, also called exhaust valve, is used in independent heating system, central heating system, heating boiler, central air conditioning, floor heating and solar heating system and other pipeline exhaust. Because there is usually a certain amount of air dissolved in water, and the solubility of air decreases with the increase of temperature, so that the gas gradually separates from the water during the water circulation, and gradually gathers together to form large bubbles or even air columns. Because of the replenishment of water, gas is often generated. When there is gas overflowing in the system, the gas will climb up along the pipeline and finally gather at the highest point of the system, and the exhaust valv...
