Research on the optimal design of a pilot valve controlling cut-off valve
The cut-offvalve based on pilot valve controlling is a new kind of valve which opens and closes fast and has low driving energy consumption.Because of the complexity of the internal flow and uncertainty of the internal pressure,there is uncertainty in the design of the key structure.We simulate the whole opening process of the valve under different key structural dimensions with Fluent Dynamic Mesh and UDFs,and we do experiments to authenticate simulation results.The turn-on time we get from the simulation is the same as that from experiments under the valves actual operating conditions,in other words,the simulation results are correct,so we can identify the valve flow and get the internal pressure data which provides a reliable basis for the design of the key structural dimensions.
