Snubber assembly and gas barrier are depending on embody rule occasion, and other devices are then essential.
Summary of the invention
It is an object of the invention to provide a kind of multistage adjustable oil sector, meet in engineering, multistage different pressure is needed for same hydraulic gear, or multistage adjustable pressure demand.
1, for completing foregoing invention object, the present invention has designed like this: a kind of multi-level adjustable hydraulic oil cylinder, it is made up of fuel feeding part, power section, traffic organising part and execution part, is connected by oil pipe between above-mentioned part, and described enforcement division is divided into takes blame for others; It is characterized in that: described power section drives two oil pumps to form two-way oil circuit by a stepper-motor to form; One road working connection, a road Pressure Increasing Oil-Line; Described traffic organising part comprises two solenoid operated directional valves; Between two solenoid operated directional valves divide to enforcement division, it is provided with pressure regulating part divide; Described two-way oil circuit is connected with corresponding solenoid operated directional valve respectively; Pressure Increasing Oil-Line by solenoid operated directional valve out after wherein a road and pressure regulating part divide series winding, after pressure regulating part divides, be connected to the propelling oil-in of execution part; Pressure Increasing Oil-Line by solenoid operated directional valve out after another Lu Zaijing mono-reversing valve be connected with the indentation oil-in performing part, or be connected with pressure protector; Described working connection through solenoid operated directional valve out after a road divide in parallel with pressure regulating part, be finally connected to the propelling oil-in of execution part by the road; Another road is connected with the indentation oil-in performing part.
Present design adopts two pump to carry out oil pressure, it is possible to realizing having mutual use between two pumps or cooperating using, wherein a road oil is mainly used for dividing fuel feeding to pressure regulating part, allows pressure regulating part divide independence oil working stability, not by the restriction of working connection; Adopt working connection to divide scheme in parallel with pressure regulating part, ensure that the fully unimpeded of oil circuit; Boost pressure regulation part only carries out oiling for propelling end, at the other end owing to no pressure needs, therefore, it is not necessary to divide through pressure regulating part.
Technique scheme is done further refinement, and it is regulate oil circuit to compose in parallel by least three tunnels that described pressure regulating part divides, and wherein two-way is made up of a solenoid operated directional valve and a microflow-control valve respectively above; Last road regulates oil circuit to be made up of an independent microflow-control valve, and every road regulates and is provided with check valve between oil circuit. Adopting multi-channel parallel mode, be mainly beneficial to the control of oil circuit, be provided with one-way cock each other and prevent from flowing backwards, every bar branch road all has reversing valve, as the setter whether oil circuit really works; In addition, every bar branch road is also provided with microflow-control valve, sets the pressure of every bar branch road with this, and the pressure reaching every bar branch road is all not identical; This kind of combination just can produce to be greater than the adjustment pressure of branch road sum.
Technique scheme is carried out further perfect, before Pressure Increasing Oil-Line enters indentation oil-in, also it is connected to two direct acting surplus valves and a shock-proof pressure gauge.
Before main oil is connected to electromagnetic switch magnetic, it is connected on one in addition and protects oil circuit; Before working connection is connected to solenoid operated directional valve, it is connected on one in addition and protects oil circuit; Described upper protection oil circuit connects a pipeline through working connection, through the most terminating oil return box of solenoid operated directional valve and a series of auxiliary oil way. Before Pressure Increasing Oil-Line is connected to solenoid operated directional valve, through a reversing valve, a road is connected to protection oil circuit; Described upper protection oil circuit connects a pipeline through working connection, and through the most terminating oil return box of reversing valve and a series of auxiliary oil way, the implementation of port of execution part is received on another road.
Such scheme is to ensure, security and be the auxiliary oil way that pressure-regulating portion is arranged, thus fully allow his pressure-regulating portion divide the more stable of work, safer.
This patent adopts pressure regulation mechanism, it is achieved allows to same oil sector, produces multiple pressure, it is achieved multistage change, pressure adjustable, is realizing quite practicality in work.
Accompanying drawing explanation
Fig. 1 is the interface chart of the present invention.
Embodiment
As shown in the figure, a kind of multi-level adjustable hydraulic oil cylinder, it is by fuel feeding part, power section, traffic organising part and execution part, is connected by oil pipe between above-mentioned part, and described enforcement division is divided into takes blame for others; Described power part drives two oil pumps 21,12 to form two-way oil circuit by a motor 11 to form; One road working connection 2, tunnel Pressure Increasing Oil-Line 1; Described traffic organising part comprises two solenoid operated directional valves 22,13; It is provided with pressure regulating part to performing between part 4 at two solenoid operated directional valves to divide; Described two-way oil circuit 1,2 is connected with corresponding solenoid operated directional valve 22,13 respectively; Pressure Increasing Oil-Line 1 by solenoid operated directional valve 13 out after wherein a road and pressure regulating part divide series winding, after pressure pressure regulation power adjustment portion, be connected to the propelling oil-in of execution part; Pressure Increasing Oil-Line 1 by solenoid operated directional valve 13 out after another Lu Zaijing mono-reversing valve be connected with the indentation oil-in performing part, or be connected with pressure protector; Described working connection 2 through solenoid operated directional valve out after a road divide in parallel with pressure regulating part, be finally connected to the propelling oil-in of execution part by the road; Another road is connected with the indentation oil-in performing part. It is regulate oil circuit to compose in parallel by least three tunnels that described pressure regulating part divides, and the present embodiment is, wherein multichannel is made up of a solenoid operated directional valve 31,33 and a microflow-control valve 32,34 respectively above; Last road is the microflow-control valve independent by, is provided with check valve between every bar branch road. Before oil circuit enters indentation oil-in, also it is connected to two direct acting surplus valves and a shock-proof pressure gauge. Before working connection is connected to first solenoid operated directional valve, it is connected to a upper protection oil circuit 6 in addition; Described upper protection oil circuit 6 connects a pipeline through working connection 2, through reversing valve and the most terminating oil return box of a series of auxiliary oil way 61.
