Fill in the blanks: The function of the breather valve flap is (), it is installed below () and extends into the tank. Answer: Reduce evaporation losses of oil products; fire extinguisher
Reduce evaporation losses of oil products, fire suppressors
Reduce evaporation losses of oil products; fire suppressors
Reduce evaporation losses of oil products; fire suppressors
When the pressure inside the tank drops rapidly and a large amount of air is drawn into the tank, the airflow blocked by the baffle is unable to strike the oil surface directly, thereby reducing further evaporation of the oil. At the same time, due to the deflection effect of the baffle, the airflow is directed from a vertical direction to a horizontal one; the fresh air drawn in first mixes with the gas at the top of the tank, where the oil and gas concentration is low, thereby further reducing its concentration. When the oil tank stops dispensing oil and starts receiving it, what is expelled is a mixture with a lower concentration of oil and gas at the top, thereby reducing losses. Fire suppressor
