Description of drawings
Fig. 1 is the utility model structural representation.
In figure, the 1-cabinet, the 2-control valve, the 3-filter, 4-manifold block, 5-are arranged solenoid valve soon, 6-hand-operated direction valve, 7-hand pump.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail, but mode of execution of the present utility model is not limited to this.
Embodiment:
The utility model structure as shown in Figure 1, actuator and control mechanism adopt the split-type structural design, described actuator is lineal travel or angle stroke motion device, in order to control valve.The utility model is provided with cabinet 1.The working environment of actuator is scarcely fine, and dust is many, and vibration is large, and temperature is high.Extraneous vibration usually can make the element of hydraulic system get loose, and vibration also can cause certain damage to electronic parts and components for a long time, affects system lifetim.Cabinet 1 of the present utility model is contained in inside with hydraulic control system, has eliminated external vibration, also a large amount of dusts is isolated in outside cabinet 1, and hydraulic system has been played good protective action.In the utility model, the fondational structure of hydraulic control system is manifold block 4, is provided with filter 3, control valve 2 on manifold block 4, arranges solenoid valve 5 and hand-operated direction valve 6 soon, and hand-operated direction valve 6 place one side joints are to hydraulic station.Wherein, control valve 2 is Proportional valve or servovalve.The quantity of filter 3 is two, and operator can use hand-operated direction valve 6 to realize two switchings between filter 3.
