Abstract
The experimental profiles of the thrust from the fluid on the valve shutter and of the gate outlet flow volume on variation in the shutter height can be generalized to geometrically similar valves. Three sets of experiments confirm the viability of the numerical method for forecasting the practical performance of safety valves. But the profile experimental diagram has to be supplemented by the pressure flow volume diagram based on the spring rigidity and prestress, the nature of the fluid, the upstream temperature and the downstream pressure. Then the calculation procedure can be extremely rapid, and the functional parameters influencing the behaviour of a valve can undergo controlled variation to determine the performance data.
