【Abstract】 This paper systematically describes the dynamic quality of synchronization valves and it’s influence on flow-dividing accuracy. Based on a set of nonlinear differential equations, transfer function of the valve is derived by means of replacing-variable and iinearization methods. The influence of the parameters of the valve(in particular the spring rigidity of the valve rod) on flow-dividing accuracy is analysed in the rate of self-regulation and the steady-state error. The results obtained are useful for the designing of synchronization valves.更多还原
