An Analytical Investigation of the Characteristics of Four-Nozzle Flapper Valve
4-노즐 플렙퍼 밸브 특성에 대한 해석적 고찰
Abstract
The static characteristics of four-nozzle flapper valves are investigated with both constant flow and constant supply pressure. The ranges, in which linearization of these characteristics would be valid, are discussed. Linearized dynamic model is also derived. Numerical simulations of nonlinear dynamic model are carried out by HyPneu to make an assessment of the effect of input step size in both cases of no-load and blocked-load operation.
