CONSIDERATIONS REGARDING THE BUTTERFLY VALVE MODEL DESIGN TO PERFORM THE EXPERIMENTAL RESEARCH
The paper presents a model of butterfly valve designed to perform experimental research in the laboratory to determine the functional parameters of industrial (prototype) butterfly valve. The model is designed considering the Froude similarity criterion based on the geometric dimensions and the design of the prototype valve having a nominal diameter of 4.9 m and operates at a pressure of 17.1 bar. The paper presents adaptations designed model can be mounted on the test bench for hydraulic turbines and experimental research can be obtained putting in optimal conditions.
