Abstract

A valve with a silicon diaphragm was developed to control the working fluid flow rate of a fluid coupling which was used to maintain the discharge pressure of a pump. The silicon diaphragm was deformed by the discharge pressure of the pump. The working fluid flow was controlled by changing the valve throat area determined by the deformation. The performance of the flow rate control valve was assessed in a test facility. Due to the characteristics of the hyper-elastic material, the trends of deformation, throat area of the valve, and flow rate were not identical during pressurization and depressurization processes. However, the control valve demonstrated an excellent performance during a test of a pressure control system consisted of the flow rate control valve, fluid coupling and a pressurizing pump. An average deviation of 2.1% was observed from the discharge pressure setting in the system.


Keywords: Diaphragm valve, Flow rate control, Fluid coupling, Hyper-elastic material, Pressurizing pump
