Described fully-hydraulic electric fork truck multiway valve is characterized in that described inclined valve, a lift valve and walking valve are three six-way valves, is respectively equipped with overflow check valve group on it, can make safety valve usefulness, can play the slow supply oil effect again, realizes the multiple spot pressure control.
Described fully-hydraulic electric fork truck multiway valve is characterized in that offering on the attaching parts oil outlet; One end of valve block connects a reducing valve, and communicating with main hydraulic fluid port and oil outlet respectively into and out of hydraulic fluid port of reducing valve worked for the aux. controls element to export the operating on low voltage medium from oil outlet; One end of inclined valve connects a safety valve, and the communicating with main hydraulic fluid port and oil return line respectively into and out of hydraulic fluid port of safety valve is with control system pressure.
Described fully-hydraulic electric fork truck multiway valve, it is characterized in that being provided with three-position four-way valve between main hydraulic fluid port and the attaching parts, the oil inlet of described three-position four-way valve communicates with the reducing valve oil outlet, in order to stroking mechanisms such as control variable oil pump and oil motors, has expanded the function of former multiway valve.
The utility model is set up two oil inlets on the basis of an oil inlet of former multiway valve, respectively to dump ram, lift oil tank and driving oil circuit fuel feeding, output and the pressure controlled function of multiple spot have along separate routes been realized, thereby can operate separately or compound control a plurality of actuating units, satisfy the fluid control requirement of fully-hydraulic electric fork truck.Simultaneously, from be total to the pump oil circuit, tell relief circuit low pressure aux. controls element and stroking mechanism are controlled, realized the common oil pump feed of a plurality of actuating units.
