Description
Technical field
The utility model relates to a kind of hydraulic control final controlling element, particularly relates to the supporting hydraulic control final controlling element of part turning valve such as a kind of and butterfly valve, ball valve, butterfly check valve.
Background technique
Current heavy hammer type hydraulic control slow closing valve hydraulic control final controlling element mainly is used as the transmission device of part turning valves such as pumping plant control valve, hydroturbine water intake valve.During work, utilize motor pump unit delivery pressure oil sources, promote the oil cylinder Open valve, the weight of the lifting simultaneously deposit energy, and can add and automatically lock or manually overhaul locking framework; Pull out lock earlier when closing valve, oil cylinder release then, weight falls rapidly, realizes the valve quick closing valve, cuts off most of current; Close to stroke control valve or the work of position limit switch control electromagnetic valve behind the several angle, valve enters the Slow Close state, effectively eliminates the water hammer that valve closing produces, the safety of protection pipeline main frame.Its deficiency is: in the valve closing process, only rely on weight potential energy throttle down, do not have the function of other superchargings.Make pumping plant control valve and hydroturbine water intake valve fast, hermetically closing, need enough driving torques that seal pressure is provided, this just requires to provide the weight that closes valve moment will do very heavyly, or support lever is very long, Oil pump electrical machinery power when large bore valves is supporting is joined very greatly, not only power consumption, and expend a large amount of steel, bring inconvenience for simultaneously the installation of equipment.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, provides a kind of energy-conservation, consumption reduction, the compound hydraulic control slow closing valve actuator of weight/accumulator easy for installation.
The technical solution of the utility model comprises driving mechanism, hydraulic station, weight accumulating mechanism, locking framework, electric control system; Driving mechanism mainly comprises oil cylinder, rocking arm and transmission bracket; Locking framework is made up of locked cylinder, locking solenoid valve; It is characterized in that: oil pump output circuit passage connects accumulator pressurize asphalt channel through one-way valve; Accumulator pressurize asphalt channel connects cylinder rod chamber through boost electromagnetic valve and closes the valve oil paths through driving the valve solenoid valve, opening the valve speed-regulating valve and connect oil cylinder rodless cavity and open the valve oil paths, connects locked cylinder through the locking solenoid valve.
In above technological scheme, oil cylinder rodless cavity links to each other with cylinder rod chamber by solenoid valve, stop valve and quick closing valve speed-regulating valve; After being connected in parallel, described solenoid valve, stop valve be connected in series with the quick closing valve speed-regulating valve.
The utility model beneficial effect compared with prior art is: be provided with accumulator pressurize asphalt channel between oil pump output circuit passage and locking framework, this accumulator pressurize asphalt channel is opened the valve oil paths by opening valve speed-regulating valve connection oil cylinder rodless cavity, connect cylinder rod chamber through boost electromagnetic valve and close the valve oil paths, accumulator and weight accumulating mechanism act on throttle down simultaneously when closing valve, can reduce weight volume and institute's gas-distributing motor power, has energy-conservation, consumption reduction, advantage such as easy for installation.
