摘要
介绍了减压阀的噪声允许值的确定方法，分析了减压阀运行时产生噪声的机理，并对大口径大流量提升套筒式减压阀提出了有效的降噪措施，取得了令人满意的效果。
The method
determining a decompressing valves tolerance of noise and the mechanism of noise produced
by the working valve is analyzed. The noise reduction measure for a heavy caliber and flow lifting
telescopic feed decompressing valve is adopted to get a satisfactory effect.
