摘　　要：比例式减压阀是近年来逐步推广应用的一种新型减压阀,其工作原理与传统类型的减压阀有所不同。该阀利用阀体内部活塞两端不同截面积产生的压力差来改变阀后的压力,达到减压目的。实际应用结果表明,该型减压阀结构简单,减压比例准确可靠,具有安装维护方便、可大流量通行等优点,可在电站、消防、供水等单位推广应用。The proportional pressure reducing valve （PPRV） is a new type of pressure reducing valve that promoting in recent years. It is different from the traditional type of pressure reducing valve, It achieves decompression through the difference pressure at two end of cross-sectional area of piston. The application results show that this valve structure is simple, the decompression ratio is accurate and reliable and the installation or maintenance is convenience. Therefore, it can applied in power plant, fire control and water supply company.
