Abstract
The utility model provides a multichannel electrohydraulic servo high pressure and low pressure oil separation device. The device comprises a general oil inlet pipe and a general oil return pipe, wherein the general oil inlet pipe is sequentially connected with a valve block, a filter, an accumulator and oil inlet pipelines of a plurality of channels; the general oil return pipe is connected with oil return pipelines of a plurality of channels; and a pilot pressure reducing valve, a direct relief valve and an electromagnetic reversing valve are sequentially arranged on the oil inlet pipeline of each channel along the oil intake direction. The multichannel electrohydraulic servo high pressure and low pressure oil separation device has the advantages that high pressure and low pressure switching operation of each channel is convenient, flexible and effective, each channel does not interfere with one another when high pressure and low pressure of each channel are switched independently, so that the expected effect is achieved.
Description
Technical field
The utility model relates to a kind of multi-channel servo high low pressure and divides oily device.
Background technique
The general shared hydraulic power unit of the hydraulic actuator of a plurality of passages; But each passage can produce interference each other when each actuator used; And the high low pressure of each passage can not regulate separately, because hydraulic pressure demand varies in size, this just need switch and adjust continually; Therefore the operation more complicated uses also very inconvenient.
Summary of the invention
Be technical deficiency more than solving, it is a kind of easy to operate that the utility model provides, and the multi-channel servo high low pressure divides oily device flexibly and effectively.
The utility model is realized through following measure:
A kind of multi-channel servo high low pressure of the utility model divides oily device; Comprise total oil inlet pipe and total return tube; Said total oil inlet pipe connects the in-line of valve piece, filter, accumulator and some passages successively; Said total return tube connects the return line of some passages, and the in-line upper edge oil-feed direction of each passage is disposed with piloted reducer, direct-acting overflow valve and solenoid directional control valve.
Be provided with pressure gauge on the in-line of above-mentioned each passage.
The beneficial effect of the utility model is:
Use this model utility, can make each passage under to the situation that does not have each other to disturb, carry out a high low pressure switching, thereby lay a good foundation for each passage works alone.Each passage high low pressure handover operation is convenient, and is effectively, noiseless each other when each passage independently switches high low pressure flexibly, arrived Expected Results.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the side structure schematic representation.
Among the figure: 1 total oil inlet pipe, 2 total return tubes, 3 accumulators, 4 filters, 5 solenoid directional control valves, 6 direct-acting overflow valves, 7 piloted reducers, 8 in-lines, 9 return lines.
Embodiment
Like Fig. 1, shown in 2; A kind of multi-channel servo high low pressure of the utility model divides oily device; Comprise total oil inlet pipe 1 and total return tube 2; Total oil inlet pipe 1 connects the in-line 8 of valve piece, filter 4, accumulator 3 and some passages successively, and total return tube 2 connects the return line 9 of some passages, and the in-line 8 upper edge oil-feed directions of each passage are disposed with piloted reducer 7, direct-acting overflow valve 6 and solenoid directional control valve 5.Be provided with pressure gauge on the in-line 8 of each passage.
The pilot port of piloted reducer 7 is communicated with direct-acting overflow valve 6, the break-make of the straight moving relief valve of solenoid directional control valve 5 controls.The high pressure of each passage is set up by piloted reducer 7, and low pressure is set up by direct-acting overflow valve 6.Hydraulic oil enters into the valve piece by total oil inlet pipe 1; Through filter 4, accumulator 3, be divided into a plurality of passages, the hydraulic oil of each passage passes through piloted reducer 7, direct-acting overflow valve 6, solenoid directional control valve 5 successively; The completion high low pressure switches, and gets into actuator then.Simultaneously, have pressure gauge, can show the system pressure of each passage.Increased piloted reducer 7, direct-acting overflow valve 6, solenoid directional control valve 5, pressure gauge, therefore possessed the high low pressure switching function, each passage is high pressure or low pressure simultaneously, can independent mutual noninterference ground work.
The foregoing description is said to be in order to specify this patent; Though describe through specific term in the literary composition; But can not limit the protection domain of this patent with this; The personage who is familiar with this technical field can change or revise it after the spirit of understanding this patent and principle and reach equivalent purpose, and this equivalence change and modification all should be covered by the claim scope and define in the category.
Claims (2)
1. a multi-channel servo high low pressure divides oily device; Comprise total oil inlet pipe and total return tube; Said total oil inlet pipe connects the in-line of valve piece, filter, accumulator and some passages successively; Said total return tube connects the return line of some passages, it is characterized in that: the in-line upper edge oil-feed direction of each passage is disposed with piloted reducer, direct-acting overflow valve and solenoid directional control valve.
