| Abstract: | The flow characteristic of the diaphragm load regulating valve for marine fresh water generator is simulated by using the CFD code of Fluent software. The open degree and mass flow rate varying with the inlet pressure under different spring rigidity is calculated and analyzed. It offers the design considerations and guidance for selecting the stiffness of spring to satisfy different regulating properties. |
