A Trial to Reduce Cavitation Noises in Control Valves

A Trial to Reduce Cavitation Noises in Control Valves

Control valves have been applied to the water supply systems of collective and multistory buildings. The noise in control valves is unwanted and annoying sound. In order to reduce the cavitation noise in control valves, we tried to modify the shape of the valve casing and the length of the orifice i...

description Control valves have been applied to the water supply systems of collective and multistory buildings. The noise in control valves is unwanted and annoying sound. In order to reduce the cavitation noise in control valves, we tried to modify the shape of the valve casing and the length of the orifice in a practical control valve. We then compared the practical valve and the modified valve quantitatively in noise and vibrational acceleration for various discharges. Here, it is worth noting that a marked reduction in cavitation noise is possible by modifying a few parts in a practical control valve.
