Overview of the composite high-speed powered air valve.
Composite high-speed power air valve is a kind of valve widely used in the water pump outlet and water supply and distribution pipelines, its main function is to eliminate the air gathered in the pipeline and prevent the pipe breaking phenomenon caused by negative pressure. The valve not only improves the efficiency of the pipeline and water pump, but also effectively avoids the problem of pipe breaking caused by negative pressure by quickly inhaling outside air.
The working principle of the composite high-speed powered air valve is quite unique. When the water pipe is filled with water, the piston or float stays in the open position and vents a lot. As the air is completely discharged, the accumulation of water in the valve causes the float to rise to the closed position, stopping the large amount of exhaust. In the process of normal water transportation in the pipe, if a small amount of air gathers to a certain extent, the water level in the valve drops, and the float drops accordingly. In this case, a small amount of air is discharged through a micro vent (integral type) or by an automatic exhaust valve vent (split type). When the water pump stops or the water flow in the pipe is emptied, generating negative pressure, the piston opens quickly to draw in air to ensure the safety of the pipeline.
In addition, the waterproof hammer exhaust valve is a special form of composite high-speed powered air valve. It further optimizes its performance by setting up a slow closing device, consisting of a throttle ring and a spring. When the water pipeline is filled with water and a large amount of gas is exhausted, the throttle ring moves until the closed position, and a large amount of gas flows out of the throttle ring hole, slowing down the exhaust speed. This effectively prevents and reduces the occurrence of shut-off water hammer. When inhaling a large amount of gas, the throttle ring is reset without throttling, ensuring that the valve can draw in a large amount of gas, further enhancing the safety of the pipeline.
In summary, the composite high-speed power air valve is an efficient and reliable valve, which provides a strong guarantee for the water pump outlet and water supply and distribution pipeline through its unique working principle and multiple functions. In the future, with the continuous progress of technology and the continuous growth of application demand, the composite high-speed power air valve is expected to play its advantages in more fields and make greater contributions to the safe and stable operation of various projects.
