Purpose of internal thread stainless steel micro exhaust valve: When water begins to fill the pipe, the plug remains in the open position to allow large amounts of air to escape. Once the air is completely expelled, water accumulates in the valve, causing the float ball to rise and drive the plug to the closed position, stopping the large-scale exhaust. During normal water transmission in the pipe, if small amounts of air accumulate in the valve to a certain extent, the water level inside the valve drops, and the float ball descends accordingly. At this point, air is released through a small hole. When the water pump stops, the pipe empties, or negative pressure occurs in the pipe, the plug quickly opens to吸入空氣, ensuring pipeline safety!
