Nuclear Engineering and Design 72 (1982) 297-301 297 North-Holland Publishing Company CAVITATION NOISE FROM BUTTERFLY VALVES William J. RAHMEYER Assistant Research Professor of Civil Engineering, Colorado State University, Fort Collins, CO 80523, USA Received 20 July 1982 Cavitation in valves can produce levels of intense noise.Butterfly valves are widely used in hydro power plants to regulate and control the flow through hydraulic turbines. That’s why it is important to design the valve in such a way that it can give best performance so that optimum efficiency can be.The paper proposes an idea of projection weighted area in designing a new control butterfly valve. A lot of three-dimensional numerical simulations are carried out on the new valve, and the numerical simulations give a good linear relationship between relative flow coefficient and relative valve opening. An experiment setup was established to verify the results of numerical simulations, and.

In this paper, a butterfly valve with the diameter of 1,800 mm was studied. Three-dimensional numerical technique by using commercial code CFX were conducted to observe the flow patterns and to measure flow coefficient, hydrodynamic torque coefficient and so on, when the large butterfly valve operated with various angles and uniform incoming velocity.

Abstract. Butterfly valves are widely used as on-off and control valves for industrial process. The importance of butterfly valves as control valves has been increasing because the pressure loss is smaller than other types of valves and compactness is very desirable for installation.

A butterfly valve is a valve that isolates or regulates the flow of a fluid. The closing mechanism is a disk that rotates. 1 Principle of operation. 2.1 Wafer-style butterfly valve. 2.2 Lug-style butterfly valve. 2.3 Rotary valve. 3 Use in industry. Principle of operation. Operation is similar to that of a ball valve, which allows for quick.
