Because the utility model discloses it in order to realize prescribing a limit to control, manual open, open and close steady, makes to have increased manual ball valve, hand -operated direction valve, balanced valve the utility model discloses can artifically prescribe a limit to and open and close, and permit to open once more and close under the circumstances of outage.
Description
Technical field
The utility model relates to building field, particularly relates to the improved structure of a kind of worm conveyor gate opening/closing hydraulic control system.
Background technology
After current worm conveyor, gate is closed rapidly in the event of a power failure, is not easy to the operations such as the repair and maintenance after power-off, inspection, and meanwhile, gate is closed rapidly may to serviceman's security presence hidden danger.
Summary of the invention
The purpose of this utility model be to provide a kind of can artificial limit's improved structure of worm conveyor gate opening/closing hydraulic control system of opening and closing and allowing again to open and close in the event of a power failure.
For achieving the above object, technical solution of the present utility model is:
The utility model is the improved structure of a kind of worm conveyor gate opening/closing hydraulic control system, comprises three-position four-way electromagnetic directional valve, equilibrium valve, check valve, manually operated directional valve, bi-bit bi-pass Solenoid ball valve, manual ball valve, gate oil cylinder, energy storage, safety unloading valve, safety valve; Described three position four-way directional control valve, equilibrium valve, manual ball valve are connected by pipeline successively with gate oil cylinder, are provided with check valve on the oil-in of three-position four-way electromagnetic directional valve; Described energy storage, safety unloading valve are connected with bi-bit bi-pass Solenoid ball valve by pipeline, and bi-bit bi-pass Solenoid ball valve is connected with manually operated directional valve by pipeline, and manually operated directional valve is connected with gate oil cylinder by pipeline; Described safety valve is other to be connected on safety unloading valve.
The pipeline road of the room, two chambeies of described gate oil cylinder is all provided with manual ball valve.
Described gate oil cylinder has two.
After adopting such scheme, control is limited owing to the utility model adds manual ball valve, use bigger energy storage instead with the pressure demand of the keying that stores 1.5 times simultaneously, when increasing a manually operated directional valve to realize power-off manually opened, increase equilibrium valve simultaneously and ensure the steady of keying, the utility model artificial limit can be opened and closed, and allow in the event of a power failure again to open and close.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is structure iron of the present utility model;
Fig. 2 is the schematic diagram of the utility model closed shutter;
Fig. 3 is the schematic diagram of the utility model starting gate.
Embodiment
As shown in Figure 1, the utility model is the improved structure of a kind of worm conveyor gate opening/closing hydraulic control system, comprises three-position four-way electromagnetic directional valve 1, equilibrium valve 2, check valve 3, manually operated directional valve 4, bi-bit bi-pass Solenoid ball valve 5, manual ball valve 6, two gate oil cylinders 7, energy storage 8, safety unloading valve 9, safety valve 10.
Described three position four-way directional control valve 1, equilibrium valve 2, manual ball valve 6 are connected with two gate oil cylinders 7 respectively successively by pipeline, are provided with check valve 3 on the oil-in of three-position four-way electromagnetic directional valve 1. The pipeline road of the room, two chambeies of gate oil cylinder 7 is all provided with manual ball valve 6.
Described energy storage 8, safety unloading valve 9 are connected with bi-bit bi-pass Solenoid ball valve 5 by pipeline, and bi-bit bi-pass Solenoid ball valve 5 is connected with manually operated directional valve 4 by pipeline, and manually operated directional valve 4 is connected with gate oil cylinder 7 by pipeline; Described safety valve 10 is other to be connected on safety unloading valve 9.
As shown in Figure 1-Figure 3, principle of work of the present utility model:
Under normal circumstances, 1) hydraulic system control oil circuit high-pressure oil is connected with gate oil cylinder 7 through three position four-way directional control valve 1, equilibrium valve 2, ball valve 6 by the P mouth of three position four-way directional control valve 1. When equipment normally runs, bi-bit bi-pass Solenoid ball valve 5 electric, the oil circuit of energy storage 8 hydraulic circuit and gate oil cylinder 7 is disconnected, by the switch of three position four-way directional control valve 1 thus realize stretching of gate oil cylinder 7.
2) in energising maintenance situation, serviceman, by the manual ball valve 6 of closed shutter oil cylinder 7, limits the automatic closedown that gate causes because of unexpected power-off, ensures that serviceman enters the safety of maintenance from mud mouth.
3) in abnormal power-down situation, three position four-way directional control valve 1 dead electricity is in middle position, and bi-bit bi-pass Solenoid ball valve 5 dead electricity makes energy storage 8 oil circuit and gate oil cylinder 7 oil circuit UNICOM, impels gate oil cylinder 7 to reclaim fast, ensures equipment use safety.
4) in power-off maintenance situation, gate is carried out repair and maintenance inspection, need to manually pull solenoid operated directional valve 4, gate is opened, and manual ball valve 6 is closed, thus carry out inspection and the repair and maintenance of gate oil cylinder 7, open manual ball valve 6 after maintenance, energy storage 8 oil circuit again with gate oil cylinder 7 UNICOM, gate is closed again.
Emphasis of the present utility model is just: is provided with manual drain charge ball valve, is provided with manually operated directional valve, Large Copacity energy storage, be provided with equilibrium valve.
The above, it is only the better embodiment of the utility model, therefore the scope of the utility model enforcement can not be limited with this, the equivalence namely done according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
