摘要：

To investigate the noise radiation in the leakage of the safety valve. The acoustic fluid-solid coupling simulation analysis of the leakage process of the safety valve is used to study the flow field when the safety valve is leaking. The sound source characteristics of different inlet pressures and different leakage holes when the internal leakage of the safety valve occurs are analyzed, and the noise source is analyzed in combination with the flow field simulation. The results show that when the internal leakage of the safety valve occurs, the noise is mainly dominated by the quadrupole sound source caused by the jet, accompanied by the dipole sound source. At the same time, the noise sound pressure level is positively correlated with the working medium pressure of the safety valve and is quadratically correlated with the inner leakage hole.
