Technical analysis of electro-hydraulic hitch control valve
The technical characteristics and control principle of the current mainstream electro-hydraulic hitch control valve were systematically analyzed,and the technical differences between the electric proportional control valve and the digital valve were put forward,which provided constructive suggestions for the design of the electro-hydraulic hitch control valve.The inherent development law of the technical route of electro-hydraulic lifting control valve was analyzed from the level of working conditions.As the core component of electro-hydraulic lifting system,the development route of electro-hydraulic lifting valve represents the development trend of electro-hydraulic lifting system,which poined out the direction for the design and selection of hydraulic system as well as machine.
