Above -mentioned power station is hydraulic control system for water intaking valve adopts the liquid accuse inlet valve of digital ball valve design, has overcome the shortcoming of above motor control flap, guiding valve liquid accuse valve, and the reliability, the security that have improved inlet valve greatly make unit running cost greatly reduced, have improved the generated energy in power station.
Description
Technical field
The utility model relates to hydraulic control system, specifically a kind of power station water intaking valve hydraulic control system.
Background technology
What power station conventionally adopted is that motor-driven valve carries out valve control, and because the particular surroundings in power station causes motor moisture-sensitive, Electric Machine Control fault rate is high, and Electric Machine Control adopts is mechanical gear box control, huge structure, and cost is high, poor reliability; Under power failure or other failure condition, cannot realize the open and close control to valve simultaneously, make hydroelectric station operation have uncontrollable potential safety hazard.
For solving the deficiency of said electric valve control, adopt guiding valve to solve these problems, but the control system of sliding valve structure exists that leakage rate is large, contamination resistance is poor, and the dwell time is short, pump start is problem frequently; A large amount of fluid is revealed the use cost that has increased power station, and the frequent starting of oil pump reduced the service life of system, has increased again the fault rate of system; Meanwhile, when situation about breaking down in system, without any aux. pressure, cannot realize the open and close control to valve, make power station operation have uncontrollable potential safety hazard.
Summary of the invention
Goal of the invention of the present utility model is: for above-mentioned the deficiencies in the prior art, provide a kind of stable, without leakage, environmental protection, safe and reliable power station water intaking valve hydraulic control system.
The technical scheme that the utility model adopts is: a kind of power station water intaking valve hydraulic control system, comprise hydraulic cylinder, and described hydraulic cylinder has rod chamber loop and rodless cavity loop; The oil-feed action in described rod chamber loop is moved by the second digital solenoid valve and the first hydraulic control one-way valve control by the first digital solenoid valve and check valve control, oil return; The oil-feed action in described rodless cavity loop is moved by the 4th digital solenoid valve and the 3rd hydraulic control one-way valve control by the 3rd digital solenoid valve and the second hydraulic control one-way valve control, oil return.
Further, the oil supply system in described rod chamber loop and rodless cavity loop is made up of check valve, oil pump, filter and fuel tank.
Further, the oil supply system in described rod chamber loop and rodless cavity loop is provided with at least one accumulator.
The beneficial effects of the utility model are: above-mentioned power station water intaking valve adopts the hydraulic control inlet valve of digital ball valve design by hydraulic control system, overcome the shortcoming of above Electric Machine Control valve, guiding valve fluid-control valve, reliability, the security of inlet valve are greatly improved, unit operation cost is reduced greatly, improved the generated energy in power station; Simultaneously, because system adopts the design of accumulator supplementary energy, under unexpected power failure or other failure condition, under the aux. pressure oil sources effect of accumulator, can realize the open and close control to valve, ensure the security of Hydropower Plant, overcome the major defect of above-mentioned Electric Machine Control valve and guiding valve fluid-control valve.
