Axial flow type pressure reducing valve

The invention provides an axial flow type pressure reducing valve, and belongs to the technical field of pressure reducing valves. The valve comprises a closed cavity, a valve element and a corrugated pipe assembly. One end of the corrugated pipe assembly is contacted with the valve core, and the other end is contacted with the outlet; a medium flows from the inlet along the axis of the closed cavity and flows out through the outlet. The axial flow type pressure reducing valve is simple and compact in structure, long in service life and capable of continuously outputting at constant pressure and flow for a long time, a medium flows along the axis of the pressure reducing valve from the inlet and flows out through the outlet, the defects of indirect flowing of the medium and change of the flowing direction are completely avoided, the flowing direction of the medium is stable, and the flowing speed of the medium is uniform. 本发明提供了一种轴流式减压阀，属于减压阀技术领域。本发明包括密闭腔体、阀芯和波纹管组件；波纹管组件一端与阀芯相接触，另一端与出口相接触；介质从进口沿密闭腔体的轴线流动，经出口流
