Abstract

In the process of assemblage, it is often a case that the pressure of load chambers inside the valve is unstable. A cavitation model of deflector jet valve’s internal fluid cavity is established so that the formation of cavitation inside deflector jet valve is related to flow field internal pressure distribution, and how to cavitation impact of valve stability. The formation of cavitation at the end of surface is simulated and analyzing that cavity gives rise to violent cavitation how to impact of valve stability. Qualified and unqualified valves are made to work under continuous high pressure so that the erosion of top and bottom end faces and the result highly proves the correctness of simulations experiments. The reasons for the failure of the valve body have been found out, and the improvement measures have been proposed.
