Double Orifice Air Release Valve

Double orifice air release valve is a key equipment used in water supply and drainage systems to remove air from pipelines and maintain stable system operation. With its unique design and efficient performance, it plays an indispensable role in various fluid transportation projects.

The valve consists of a valve body, float, lever, valve seat and other components, and has two exhaust ports, one large and one small. Its working principle is based on the characteristic of the float rising and falling with the change of water level: when the pipeline is filled with water or running, the air inside the pipeline gathers at the exhaust valve. At this time, the float drops due to buoyancy, and the large exhaust port opens, quickly discharging a large amount of air; As the water flow fills the pipeline, the floating ball rises to block the large exhaust port. When small bubbles are generated and accumulate during system operation, the floating ball descends again, and the small exhaust port opens to continuously discharge tiny air, ensuring that the pipeline is always in a good full water state.

The advantages of a double orifice air release valve are significant. The design of the large and small dual exhaust ports takes into account the needs of quickly removing a large amount of air and continuously removing small bubbles. It can not only shorten the water injection time of the pipeline, improve the system startup efficiency, but also avoid air resistance and water hammer caused by residual air, reduce pipeline vibration and noise, effectively protect the pipeline and ancillary equipment, and extend the service life. At the same time, its structure is simple and compact, easy to install and maintain, with good sealing performance, and can adapt to water supply and drainage systems with different pipe diameters and pressure conditions.

In practical applications, double orifice air release valves are widely used in urban water supply networks, sewage treatment plants, industrial circulating water systems, agricultural irrigation pipelines, and other scenarios. Whether it is ensuring stable water supply for urban residents or maintaining smooth water circulation in industrial production, it can ensure efficient and safe fluid transportation through timely exhaust, becoming a reliable guarantee for the stable operation of the water supply and drainage system.
