Experimental study on vibration and noise of throttle valve in water-conveying systems
In the water conveying system, the throttle valve has a great impact on the vibration and noise, which needs to be controlled. In this paper, a noise test bench for throttle valve in water conveying system is established. The vibration, air noise and flow noise are measured under different pressure...

| description | In the water conveying system, the throttle valve has a great impact on the vibration and noise, which needs to be controlled. In this paper, a noise test bench for throttle valve in water conveying system is established. The vibration, air noise and flow noise are measured under different pressure differences and flow rates for throttle valves with different structures and diameters. The results show that the throttle valve vibration and air noise increase with the increase of pressure difference and flow when the noise is above 70 dB(A). When the pressure difference is more than 0.5MPa, the flow noise of ordinary ball valve is mainly in the high frequency range. The vibration, noise and pipeline flow noise of the low-noise valve with multistage throttling are significantly reduced, and the flow noise is mainly in the low frequency band below 315Hz. The pipe flow noise in front of the throttle valve is broadband which decreases with the increase of frequency. Increasing the pressure behind the throttle valve can reduce the valve vibration under the same pressure difference. |
