该文提出一种检测溢流阀内泄漏量的新方法。提出应用气动量仪检测溢流阀液体泄漏量的理论依据。通过试验证实这种检测方法对于改进溢流阀的结构设计及制造工艺是一种准确、清晰的研究方法，对于溢流阀出厂试验时内泄漏量指标的在线测量是一种高效、省力、能耗低的方法。
This paper presents a new method for detecting the amount of leakage in a relief valve. A theoretical basis for detecting the amount of liquid leakage from a relief valve by using a pneumatic gauge is proposed. The test proved that this method is an accurate and clear method to improve the structural design and manufacturing process of the relief valve. The on-line measurement of the internal leakage index during the factory test of the relief valve is an efficient, Low consumption method.
