Develop the Low Pressure Large Flow Overflow Valve

Abstract

In the paper, for high-power marine overflow valve of low pressure big traffic problems, the design of the inside leaking mouth leaks in parallel structure ,that is suitable for the different oil and water flow, using additional flow beam, guiding type low pressure large flow overflow valve was developed and the experimental study, obtained the dynamic and static parameters of the valve. Invented the inside leaking and leaked mouth parallel connection structure, inside leaking and leaked mouth parallel connection is established the mathematical model of the overflow valve. Results show that compared with the traditional straight moving type overflow valve, the type overflow valve through a larger flow, has better dynamic and static performance and cavitation resistance.
