Working Principle of Double Orifice Air Valve

The working principle of the Double Orifice Air Valve is based on the principle of air pressure difference. When the internal pressure of the system is higher than the set value, the valve will automatically open to discharge the air or other gases inside the system; When the pressure returns to normal, the valve will automatically close to prevent external air or gas from entering the system. Specifically, double hole air valves are usually installed at high points or locations in pipeline systems where gas is prone to accumulate. When gas is present in the pipeline system, it accumulates above the valve, pushing the internal float or piston up, thereby opening the exhaust port. With the emission of gas, the float or piston descends and closes the exhaust port again to prevent liquid loss; When air needs to be introduced, the float or piston mechanism can also respond to pressure changes and automatically open the air inlet.

Structural characteristics 

Double Orifice Air Valve typically use a float or piston mechanism, which allows the valve to quickly expel or introduce a large amount of air in a short period of time. Its characteristics include efficiency, multifunctionality, reliability, and adaptability. Efficiency is reflected in the ability to remove or introduce a large amount of gas in a short period of time; The multifunctionality is reflected in the ability to emit both trace amounts of exhaust and large amounts of intake and exhaust, suitable for various working conditions; Reliability is demonstrated by the ability to operate stably even under large pressure differentials; Adaptability is reflected in its suitability for various media, such as clean water, sewage, seawater, etc.

Application scenarios

Double Orifice Air Valve are widely used in various industrial fields, including:

1.Water supply system: used to remove air from pipelines and avoid air blockage.

2.Drainage system: used to quickly introduce air and ensure smooth pipeline flow.

3.Wastewater treatment: used for automatic air discharge to prevent system blockage.

4.Seawater treatment: used to remove air from water tanks or pipelines to ensure that water quality is not affected.

5.Industrial pipelines: used for automatic exhaust to improve system efficiency and safety.
