FEM Analysis and Structure Improvement of Pinch Valve

Abstract:

Pinch valve is an important flow adjusting device in the operating system of polymer materials with characteristics of high viscosity and high solid content, and its service life limits its application and popularization. In this study, for the special application environment and requirements of clevis pinch valve in the operating system, the dual-parameter Mooney-Rivlin constitutive model of rubber and Linear Elastic model of clevis were used. The stress and strain distributions of the rubber hose, while completely closed, were obtained by means of FEM (Finite Element Method) analysis. Parameters of hose thickness and cone length of the rubber hose were optimized, and the structure-improved pinch valve was obtained as well. The strain energy release rate and fatigue life were analyzed for the improved rubber hose at the most dangerous cell.
