Background technique
At present, the pressure and flow compound control that propulsion hydraulic system many adoption rates relief valve combines with proportional velocity regulating valve, this controlling method element is many, structure relative complex, pressure is grouping control, and often organize pressure relatively stable be with by the invalid overflow of each group of proportional pressure control valve for cost obtains, energy loss is large, and cost overall operation is high.
Summary of the invention
In order to overcome the pressure controlled circumscribed deficiency of advancing hydraulic pressure in above-mentioned prior art, the utility model provides a kind of proportional pressure-reducing valve of having connected on propelling cylinder control loop, during driving, passing ratio reduction valve realizes the propulsion control valve group of the single pressure adjustable that oil cylinder working-pressure controls.
The purpose of this utility model is achieved in that
Single pressure adjustable propulsion control valve group, comprise valve body, be arranged on the unloading valve 4 on valve body, proportional pressure-reducing valve 6, safety overflow valve 7, cartridge valve 8, pressure transducer 10, pressure measuring tie-in 12 and cover plate 13, the damping port 3 be connected with cover plate 13, and for controlling the PLC of said modules;
Described pressure transducer 10 connects propelling cylinder 11;
Described Solenoid ball valve 9 is connected in reclaim line, connects cartridge valve 8 simultaneously; Cartridge valve 8 connects unloading valve 4, the management between unloading valve 4 and cartridge valve 8 is provided with damping port 3;
Described propelling cylinder 11 connects the second one-way valve 5, second one-way valve 5 by pipeline and connects proportional pressure-reducing valve 6;
Described propelling cylinder 11 connects between the second one-way valve 5 pipeline is parallel with the first one-way valve 1 and follow-up one-way 2.
positive beneficial effect:the utility model is according to actual applying working condition and hydraulic characteristic, and it is adjustable that passing ratio reduction valve realizes single oil cylinder working-pressure, can realize the servo-actuated action of oil cylinder simultaneously, be divided into groups arbitrarily simultaneously by PLC to propelling cylinder, the efficient attitude controlling shield structure.Can be applicable to shield driving control system; Cost is lower, easy to maintenance.
Accompanying drawing explanation
Fig. 1 is hydraulic schematic diagram of the present utility model;
Fig. 2 is structural representation one of the present utility model;
In figure be: the first one-way valve 1, follow-up one-way 2, damping port 3, unloading valve 4, second one-way valve 5, proportional pressure-reducing valve 6, safety overflow valve 7, cartridge valve 8, Solenoid ball valve 9, pressure transducer 10, propelling cylinder 11, pressure measuring tie-in 12, cover plate 13.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 2, single pressure adjustable propulsion control valve group, comprise valve body, be arranged on the unloading valve 4 on valve body, proportional pressure-reducing valve 6, safety overflow valve 7, cartridge valve 8, pressure transducer 10, pressure measuring tie-in 12 and cover plate 13, the damping port 3 be connected with cover plate 13, and for controlling the PLC of said modules;
Described pressure transducer 10 connects propelling cylinder 11;
Described Solenoid ball valve 9 is connected in reclaim line, connects cartridge valve 8 simultaneously; Cartridge valve 8 connects unloading valve 4, the management between unloading valve 4 and cartridge valve 8 is provided with damping port 3;
As shown in Figure 1, described propelling cylinder 11 connects the second one-way valve 5, second one-way valve 5 by pipeline and connects proportional pressure-reducing valve 6;
Described propelling cylinder 11 connects between the second one-way valve 5 pipeline is parallel with the first one-way valve 1 and follow-up one-way 2.
The utility model passing ratio reduction valve can electrodeless adjustment propelling pressure; Control valve group is furnished with follow-up one-way, oil cylinder can be made to be undertaken servo-actuated by low pressure; Control valve group is furnished with safety overflow valve, overload protection is carried out to system., by PLC electrical control, propelling cylinder is divided into groups meanwhile, realize the tuning action of shield structure four direction.
Under assembled pattern: carry out by the cartridge valve of large discharge the control that oil cylinder stretches out and reclaim, simultaneously in reclaim line, string has Solenoid ball valve, when oil cylinder reclaims Solenoid ball valve first electric off-load is carried out to pressure, reduction oil cylinder affects the impact of cartridge valve.
Under boring mode: the electrodeless adjustment being carried out pressure by the proportional pressure-reducing valve often organized in controll block, valve group is equipped with safety overflow valve, limits system pressure maximum, overload protection is carried out to system, also by host computer interface, oil cylinder is divided into groups arbitrarily simultaneously.
Follower model: when tunneling, if do not need certain to follow oil cylinder to exert oneself, especially with the oil cylinder of displacement transducer, now this controll block proportional pressure-reducing valve does not work, provides low pressure oil sources to carry out low pressure to this oil cylinder by follow-up one-way and follows.
The utility model is according to actual applying working condition and hydraulic characteristic, and it is adjustable that passing ratio reduction valve realizes single oil cylinder working-pressure, can realize the servo-actuated action of oil cylinder simultaneously, be divided into groups arbitrarily simultaneously by PLC to propelling cylinder, the efficient attitude controlling shield structure.Can be applicable to shield driving control system; Cost is lower, easy to maintenance.
Above embodiment is only for illustration of preferred implementation of the present utility model; but be of the present utility modelly not limited to above-mentioned mode of execution; in the ken that described exercising ordinary skill possesses; the any amendment done within spirit of the present utility model and principle, equivalently to substitute and improvement etc., it all should be encompassed within the technological scheme scope of request protection of the present utility model.
