The invention discloses a pressure reducing valve. The pressure reducing valve comprises a main valve body. A valve cavity is formed inside the main valve body. The main valve body is provided with avalve outlet and a valve inlet, wherein the valve outlet and the valve inlet communicate with the valve cavity. Two or more pressure reducing devices are arranged between the valve inlet and the valveoutlet, wherein the pressure reducing devices are suitable for draining fluid at the valve inlet to the valve outlet after the fluid is depressurized. The pressure reducing valve is small in occupiedspace, low in cost and small in number of high-pressure leakage points; all the pressure reducing devices share the same main valve body, are independent of one another, do not interfere with one another and can be switched flexibly or used at the same time. 本发明公开了种减压阀。所述减压阀包括主阀体，所述主阀体内成型有阀腔；所述主阀体上设置有与所述阀腔连通的阀出口和阀入口；在所述阀入口和所述阀出口之间设置有至少两个适于将所述阀入口的流体进行减压后排至阀出口的减压装置。所述减压阀占用空间小、成本低且高压泄漏点少，各减压装置共用个主阀体，彼此之间相互独立，互不干扰，可灵活切换或者同时使用。
