Characteristics research of a cartridge type electrical closed-loop proportional throttle valve
Abstract:The electro-hydraulic proportional flow control valve is the core component of the proportional control technology, its role is to continuously control the flow of the hydraulic system. Among them, the proportional throttle valve structure is simple, low cost, fast dynamic response, stability and reliability,it is widely available in industrial production. Therefore, this paper presents a proportional throttle valve, the structure and working principle are introduced, and the valve through the simulation software simulationX modeling and simulation analysis to determine the parameters of the main structure of the valve. Simulation results show that the electrical closed-loop control proportional throttle valve has good accuracy and dynamic response. Little change in the load to use the occasion is relatively economical and reasonable choice.
Keywords: proportional throttle valve electrical closed-loop characteristics research
