Abstract
The utility model provides a control system of a vertical roller balance hydraulic cylinder. The control system mainly comprises a transmission-side vertical roller balance hydraulic cylinder working loop and an operation-side vertical roller balance hydraulic cylinder working loop, wherein a stop valve is connected on an oil pipe between an oil inlet and an oil outlet of a balance hydraulic cylinder in series, a direct-acting overflow valve is connected between the stop valve and an oil inlet pipe in series, a stacked bidirectional and unidirectional throttle valve is connected between an electromagnetic reversing valve and the stop valve in series, and the electromagnetic reversing valve is connected between the stacked bidirectional and unidirectional throttle valve and a pressure-reducing valve in series. The control system disclosed by the utility model has the benefits that the electromagnetic reversing valve is not charged in neutral position, even back pressure in return oil is increased, as two ports of the electromagnetic reversing valve and the balance hydraulic cylinder, which are connected, are not communicated, mis-actions of movement of a piston rod of the vertical roller balance hydraulic cylinder can be avoided, and the reliability of a hydraulic system can be further improved.
Description
Technical field
The utility model relates to a kind of hydraulic cylinder and controls system, particularly relates to a kind of edger roll balance hydraulic cylinder and controls system.
Background technology
Edger roll balance hydraulic cylinder control system is mainly become with fore side edger roll balanced hydraulic cylinder working loop sets by transmission side edger roll balanced hydraulic cylinder working loop.Under the effect of hydraulic control system; The edger roll balance hydraulic cylinder can realize advancing, retreat, stopping three kinds of actions, but in the roll change process, may produce a problem, when solenoid directional control valve is not charged; If return oil pressure raises; Because solenoid directional control valve and two mouthfuls of connections that the superposing type Double throttle check valve is connected with balance hydraulic cylinder under the effect of return oil pressure, can make the piston rod movable (load of edger roll compensating cylinder is not high) of edger roll balance hydraulic cylinder; Thereby plant equipment is caused certain damage, the user is managed loss economically.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the utility model provides a kind of edger roll balance hydraulic cylinder to control system, to prevent the movable misoperation of edger roll balanced hydraulic cylinder piston rod.
The technical scheme of the utility model is: a kind of edger roll balance hydraulic cylinder is controlled system; Mainly become with fore side edger roll balanced hydraulic cylinder working loop sets by transmission side edger roll balanced hydraulic cylinder working loop, transmission side edger roll balanced hydraulic cylinder working loop comprises: solenoid directional control valve, superposing type Double throttle check valve, direct-acting overflow valve, pressure-reducing valve, transmission side edger roll balance hydraulic cylinder and some stop valves; Fore side edger roll balanced hydraulic cylinder working loop comprises: solenoid directional control valve, superposing type Double throttle check valve, direct-acting overflow valve, pressure-reducing valve, fore side edger roll balance hydraulic cylinder and some stop valves; Wherein stop valve is serially connected in balance hydraulic cylinder on the oil pipe between the hydraulic fluid port; Direct-acting overflow valve is serially connected between stop valve and the oil inlet pipe; Solenoid directional control valve is serially connected between superposing type Double throttle check valve and the pressure-reducing valve, and two mouthfuls of being connected with balance hydraulic cylinder of solenoid directional control valve and superposing type Double throttle check valve are not communicated with.
The beneficial effect of the utility model is: solenoid directional control valve is when meta is not charged; Even return oil pressure raises; Because two mouthfuls of not connections that solenoid directional control valve is connected with balance hydraulic cylinder; The movable misoperation of piston rod of edger roll balance hydraulic cylinder can not occur, thereby improve the reliability of hydraulic system.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is an edger roll balance hydraulic cylinder control system schematic.
Wherein: 1-solenoid directional control valve 2-adds formula Double throttle check valve 3-direct-acting overflow valve
4-pressure-reducing valve 5-transmission side edger roll balance hydraulic cylinder 6-stop valve
7-fore side edger roll balance hydraulic cylinder A, B-solenoid directional control valve hydraulic fluid port
The specific embodiment
As shown in Figure 1, this edger roll balance hydraulic cylinder control system is mainly become by the transmission side edger roll balanced hydraulic cylinder working loop in left side and the fore side edger roll balanced hydraulic cylinder working loop sets on right side.
Transmission side edger roll balanced hydraulic cylinder working loop comprises: solenoid directional control valve 1, superposing type Double throttle check valve 2, direct-acting overflow valve 3, pressure-reducing valve 4, transmission side edger roll balance hydraulic cylinder 5 and some stop valves 6; Said fore side edger roll balanced hydraulic cylinder working loop comprises: solenoid directional control valve 1, superposing type Double throttle check valve 2, direct-acting overflow valve 3, pressure-reducing valve 4, fore side edger roll balance hydraulic cylinder 7 and some stop valves 6; Wherein stop valve 6 is serially connected in balance hydraulic cylinder on the oil pipe between the hydraulic fluid port; Direct-acting overflow valve 3 is serially connected between stop valve 6 and the oil inlet pipe; Superposing type Double throttle check valve 2 is serially connected between solenoid directional control valve 1 and the stop valve 6, and solenoid directional control valve 1 is serially connected between superposing type Double throttle check valve 2 and the pressure-reducing valve 4.
Solenoid directional control valve is when meta is not charged; If return oil pressure raises; Because solenoid directional control valve hydraulic fluid port A, B are not communicated with; Return oil pressure can not cause the piston rod movable telescopic of edger roll balanced hydraulic oil cylinder, the misoperation of edger roll balanced hydraulic oil cylinder piston bar can not occur, has improved the reliability of hydraulic system.
Above embodiment can not limit the scope of the utility model with this only in order to the technical scheme of explanation the utility model; The modification that the technical scheme that aforementioned each embodiment put down in writing is carried out; Perhaps be equal to replacement to what part technical characterictic wherein carried out; Do not make the essence of relevant art scheme break away from the spirit and the scope of each embodiment technical scheme of the utility model, all should still belong in the scope that the utility model patent contains.
