Technique scheme is made to further refinement, and it is to regulate oil circuit to compose in parallel by least three tunnels that described pressure regulating part divides, and wherein multichannel is made up of a solenoid directional control valve and a Speed governing with micro-adjustment valve respectively above; Last road is the Speed governing with micro-adjustment valve independent by, between every branch road, is provided with one-way valve.Adopting multi-channel parallel mode, is mainly the control that is beneficial to oil circuit, is provided with each other one-way cock and prevents from flowing backwards, and every branch road all has selector valve, as whether real work regulator of oil circuit; In addition, the branch road is also provided with Speed governing with micro-adjustment valve, the pressure of setting every branch road with this, and the pressure that reaches every branch road is all not identical; This combination just can produce the adjusting pressure that is greater than branch road sum.
Technique scheme is carried out further perfect, before oil circuit enters indentation filler opening, be also connected to two straight moving relief valves and shock-proof pressure gauges.
Be connected to before first is solenoid directional control valve at main oil, be connected in addition a upper protection oil circuit; Described upper protection oil circuit is to connect a pipeline through working connection, finally takes back fuel tank through selector valve and a series of auxiliary oil way.Be connected to before first is solenoid directional control valve in Pressure Increasing Oil-Line, through a selector valve, a road is connected to protection oil circuit; Described upper protection oil circuit is to connect a pipeline through working connection, finally takes back fuel tank through selector valve and a series of auxiliary oil way, and the implementation of port of carrying out oil cylinder is received on another road.
Such scheme is in order to guarantee, Security and be the auxiliary oil way that pressure-regulating portion arranges, the more stable, safer of his pressure regulation some work thereby punching spares.
This patent adopts pressure-regulating device, realizes and allowing to same oil sector, produces the business of multiple pressure, realizes multistage variation, and pressure is adjustable, realize in work quite practical.
Accompanying drawing explanation
Fig. 1 is connection diagram of the present utility model.
Embodiment
As shown in the figure, a kind of Multi-stage adjustable hydraulic jack, it is by fuel feeding part, power section, flows to control section and do-part, between above-mentioned part, connects by oil pipe, and described do-part is to take blame for others; Described power part is to drive two oil pumps 21,22 to form two-way oil circuit by a stepper motor 11 to form; One road working connection 2, one tunnel Pressure Increasing Oil-Line 1; The described control section that flows to comprises two solenoid directional control valves 22,13; Divide 3 at two solenoid directional control valves to being provided with pressure regulating part between do-part 4; Described two-way oil circuit 1,2 connects with corresponding solenoid directional control valve 22,13 respectively; Pressure Increasing Oil-Line 1 by solenoid directional control valve 13 out after wherein a road and pressure regulating part divide series winding, after pressure adjusts pressure regulating part to divide, be connected to the propelling filler opening of do-part; By solenoid directional control valve 13, another Lu Zaijing mono-selector valve after is out connected with the indentation filler opening of do-part Pressure Increasing Oil-Line 1, or is connected with pressure guard 4; Described working connection 1 through solenoid directional control valve out Hou Yi road and pressure regulating part divide 3 in parallelly, be finally connected to by the road the propelling filler opening of do-part; Another road is connected with the indentation filler opening of do-part.Described pressure regulating part divides 3 to be to regulate oil circuit to compose in parallel by least three tunnels, and the present embodiment is that wherein multichannel is made up of a solenoid directional control valve 31,33 and a Speed governing with micro-adjustment valve 32,34 respectively above; Last road is the Speed governing with micro-adjustment valve 35 independent by, between every branch road, is provided with one-way valve.Before oil circuit enters indentation filler opening, be also connected to two straight moving relief valves and a shock-proof pressure gauge.Be connected to before first is solenoid directional control valve at main oil, be connected in addition a upper protection oil circuit 6; Described upper protection oil circuit 6 is to connect a pipeline through working connection 2, finally takes back fuel tank through selector valve and a series of auxiliary oil way 61.Be connected to before first is solenoid directional control valve in Pressure Increasing Oil-Line, through a selector valve, a road is connected to protection oil circuit; Described upper protection oil circuit is to connect a pipeline through working connection, finally takes back fuel tank through selector valve and a series of auxiliary oil way, and the implementation of port of carrying out oil cylinder is received on another road.
