The CARX compound air valve features a cylindrical body with internal components including a stainless steel float ball, lever, and valve disc. It is installed at pump outlets or within water distribution pipelines to remove trapped air, enhancing pipeline and pump efficiency. In the event of negative pressure, the valve rapidly draws in external air to prevent pipeline damage. Working Principle: Initial Water Filling (Exhaust Phase): When water begins filling the pipeline, the valve disc remains open, enabling rapid air release. Once air is fully expelled, water fills the valve chamber, causing the float ball to rise and close the valve disc, stopping exhaust. Normal Operation (Minor Air Release): During regular water flow, air accumulating in the valve chamber gradually lowers the water level. The descending float ball opens small orifices, allowing trapped air to escape. Emergency Protection (Negative Pressure Scenarios): During pump shutdowns, pipeline drainage, or negative pressure, the valve plug instantly opens to intake air, safeguarding the pipeline from collapse. Key Features: Eliminates air pockets to optimize pump and pipeline efficiency. Prevents pipeline collapse under negative pressure via rapid air intake. Dual-function design: large-scale exhaust during filling + localized air release during operation. Durable stainless steel float ball ensures corrosion resistance and reliability.
