Some wheel loaders steering system includes:Hydraulic Gear Pump, Loader Full Hydraulic Steering Gear, Loader Steering Control Valve, steering cylinder.
Direction control valve is the hydraulic system to control the direction of hydraulic oil flow valve parts, we also known as the hydraulic system reversing element, and flow valve, pressure valve in different direction control valve direct load control.
Hydraulic system direction control valve introduction:
Steering control valves require very little force to push the handle of the valve to control heavy loads. For example, excavators, loaders, truck cranes, etc., are controlled by the control handle. The characteristics of this kind of machinery are complex working conditions, delicate operation and complex action. Some old drivers complete a lot of incredible operations with this kind of machinery.
Hydraulic system direction control valve classification:
By function: direction control valve including one-way valve and reversing valve two categories.
According to the control mode: manual directional valve, hydraulic directional valve, electromagnetic directional valve, electro-hydraulic directional valve, etc. Multiple directional valves can be combined for multi-way valves, which can operate multiple groups of action.
Working principle of hydraulic system direction control valve:
Reversing valve is through the spool in the valve body to do axial movement, so that the corresponding oil connected or disconnected. The valve body has a plurality of sink groove, sink groove is connected with the external through the hole, the spool has a plurality of steps. Reversing valve is realized by changing the connection between the step on the spool and the sink groove on the valve body.
