Abstract
The utility model relates to the technical field of control valves, in particular to a pilot oil source valve bank. The pilot oil source valve bank consists of a valve block body, a control valve and an accumulator. The pilot oil source valve bank is characterized in that the valve block body is provided with a hydraulic control valve, the accumulator, a filter, and a command processor; after the control valve receives a command, the embedded command processor of the control valve operates valve core motion control software to realize set functions, thereby realizing complex system functions; as a pilot hydraulic valve block body is provided with the accumulator, not only can pressure fluctuation be absorbed, and a stable pilot pressure can be provided; moreover, another important function is as follows: when equipment is powered off, the energies stored by the accumulator can continuously control the work of the hydraulic valve.
Description
Technical field
The utility model relates to the control valve technical field, especially a kind of guide's oil sources valve group.
Background technique
Need bigger power to promote when the hydraulic control valve of big flow is worked, if use solenoid controlled, then winding volume is very big, and power just can meet the demands, and the coil cost is very high like this, and the volume of control valve can be very big simultaneously, and cost performance is bad; If with manually control, cost has been a step-down, but manipulation strength is big, poor working environment be the more important thing is and can not be realized telecontrol, inconvenient personnel operation.
Summary of the invention
In order to overcome the deficiencies in the prior art, it is a kind of simple in structure that the utility model provides, little and the guide's oil sources valve group that can telecontrol of volume.
Described a kind of guide's oil sources valve group, form by valve block, control valve, accumulator etc., be characterised in that described valve block has hydraulic control valve, accumulator, filter and instruction processing unit, after control valve receives instruction, its embedded instruction processing unit just moves spool action control software and realizes the function of setting, thereby realizes complicated systemic-function.
Guide's hydrovalve block is joined accumulator, except the absorption pressure Reeb, provides outside the stabilizes forerunner pressure, and the another one major function is when device powers down, and the energy of accumulator storage can also continue to control the work of hydraulic control valve.
The beneficial effects of the utility model: volume is little, and low price can be realized telecontrol and guarantee hydrovalve work when a merit machine is out of service.
Description of drawings
Fig. 1 is the utility model schematic diagram
Control valve 1, accumulator 2, filter 3, relief valve 4, valve block 5, runner 6, instruction processing unit 7
Embodiment
As shown in the figure, guide's oil sources valve group is the chief component of guide's hydraulic system in the modern hydraulic machinery, adopt with thread cartridge formula structure, it is little to have volume, compact structure, reduce pipe arrangement, good seal performance, advantages such as control range is big, can adapt to heavy duty and bad working environments etc., the design needs different according to the client, guide's oil sources valve piece can have single solenoid valve, dual-coil electromagnetic valve, forms such as three solenoid valves, also can increase accumulator and filter etc. as required, its typical case is by designing 6 mouthfuls of 6 of cuttings or a plurality of runners, in order with control valve 1 with valve block 5, accumulator 2, filter 3, relief valve 4 is installed respectively.Then, open the oil circuit mediation, accumulator 2 interfaces are got final product.Accumulator provides outside the stabilizes forerunner pressure except the absorption pressure Reeb, and the another one major function is when device powers down, and instruction processing unit 7 will can also continue to control the work of hydraulic control valve at the energy of accumulator 2 storages.
Claims (1)
1. guide's oil sources valve group is made up of valve block, control valve, accumulator, it is characterized in that described valve block is provided with hydraulic control valve, accumulator, filter and instruction processing unit.
