Design and Modeling of a Pressure Reducing Valve
Abstract：Comparing and analysis the design of two different schemes of valve structure, we select the pipe-thread pilot pressure relief valve to research, which is widely used nowadays. Refer to the structure and technical parameters of JF series of pilot pressure reducing valve, and on this basis, we can increasing the sensitivity of the valve and make it more economical and reasonable once it meet the design requirements by changing the valve plug’s core material and redesigning the values of the structural parameters; get the assembly and disassembly process flash of Pilot pressure reducing valve through drawing the three-dimensional model of it; using ANSYS software to analyzing dynamic characteristic, through calculate and optimize to increase the performance of the valve, and finally the results show that the valve can meet the expected requirements.
Key Words： pilot pressure reducing valves ; tube type conjunction; the valve core structure parameters
