What is the role of Single Orifice Air Valve

Single Orifice Air Valve refers to an exhaust valve with only one orifice as the inlet and exhaust valve ports. There are two types: large port and small port. Then what is the role of Single Orifice Air Valve? Let's learn about it with the exhaust valve manufacturer.

Single Orifice Air Valve
The large-port exhaust valve is suitable for exhausting and sucking the atmosphere. When there is no pressure water in the main pipeline, the floating ball is located at the bottom of the valve, and the orifice is open. In the water filling process, the air is discharged and the rising water level supports the float ball to the valve seat hole, and then the water pressure in the pipe seals the valve outlet; when the drainage pressure in the pipe drops to close to atmospheric pressure, the float ball falls and the air flows from the outside. To prevent vacuum in the tube.
For small port exhaust valves, the floating ball is usually close to the sealing surface of the small hole of the valve seat. When the air accumulation in the valve cavity drops, until the floating ball loses buoyancy and automatically leaves the sealing surface of the valve seat, the valve opens, and the air in the valve opens automatically. The small port is discharged, and the water level rises, the float ball is floated, and the seal is resealed. The small port exhaust valve can remove the air continuously escaping from the water body on the pipeline.
