Study on Corrosion Mechanism and Structure Optimization of Butterfly Valve
In order to improve the corrosion resistance of the sealing amplitude and the front face of a cut-off butterfly valve,this paper studies the corrosion mechanism of the cut-off butterfly valve and the front face structure of the valve plate.A new surfacing process is put forward to increase the service life of the sealing pair of the cut-off butterfly valve,and three types of cut-off butterfly valves with different spool structures are simulated by ANSYS software.The pressure distribution of the cut-off butterfly valve plate is obtained,and ANSYS software is used to optimize the cut-off butterfly valve plate front structure.The results show that the anti-corrosion ability of the sealing pair of the butterfly valve is improved using the new surfacing technology,and the pressure distribution of the cut-off butterfly valve plate is improved by optimizing the front structure of the cut-off butterfly valve plate.The corrosion resistance of the cut-off valve front is also improved.
