WebFlow-profile distortion and swirl — the two most prominent types of fluid disturbance that affect a meter’s flow coefficients — are typically the products of improper piping configuration. Fluid profile distortion occurs when an obstruction — such as a partially open valve or a poorly mounted flange gasket — partially blocks the pipe. WebSet Pressure occurs during the Proportional Opening. This is the largest increase in flow area of the valve.

WebA constant sectional area design allows the flow to be canalized into an annular flow pattern, uniformly guided by the shape of the inner and outer valve body: this design provides the fluid a symmetrical flow path with a smooth flow transition to the throat control zone, with low vibrations and low material erosion. WebCauses of Cavitation. Different specific sources of pressure changes cause cavitation, but they all arise from the flow of the liquid through the control valve. Cavitation usually begins in the low-pressure regions associated with boundary layer separation. This may occur even though the mean pressure is greater than the vapor pressure.

WebFeb 26, 2024 · In this study, a novel viscous damping system with opposing symmetrical hydraulic cylinders that can guarantee the smoothness of vibration absorption in a single degree of freedom is proposed.
