Abstract
The utility model provides an electro-hydraulic device of partial rotating valves, which is composed of a motor, a bracket, an oil pump, a hydraulic integrated block, a hydraulic cylinder, a rotating shaft, keys, a travel position limiting mechanism, etc. The utility model is characterized in that an oil cylinder driving rotating mechanism is a shifting fork sliding block mechanism. The utility model is mainly suitable for various partial rotating valves, particularly electro-hydraulic devices of large caliber ball valves and butterfly valves. The utility model has the advantages of small size, simple structure, light weight, integral structure, good outer housing protection and convenient installation and debugging.
Description
Affiliated technical field
The utility model relates to a kind of part turning valve electro-hydraulic device, belongs to a kind of valve actuator.
Background technique
Use the electro-hydraulic device on part turning valves such as ball valve, butterfly valve at present, the swirl gear of hydraulic oil cylinder driving mainly contains three kinds of pinion and racks, pull-rod type mechanism, piston rod mechanism, being characterized in exporting torque curve is a straight line, with the open and close torque characteristic curve of ball valve, butterfly valve be a parabola, promptly at the end moment of torsion is big in opening and closing, interstage, little characteristic was not inconsistent, and the output torque is little.Be not suitable for drive unit as heavy caliber ball valve, butterfly valve.
Summary of the invention
In order to overcome existing electro-hydraulic device control output torque curve and ball valve, the open and close torque characteristic curve of butterfly valve is not inconsistent, be not suitable for as the heavy caliber ball valve, the deficiency of the drive unit of butterfly valve, the electro-hydraulic device that the utility model provides a kind of part turning valve to use, the swirl gear of the electro-hydraulic device hydraulic oil cylinder driving that this part turning valve is used is the shift fork slide-block mechanism, it is a kind of boosting mechanism, the output torque characteristic of total travel and heavy caliber ball valve, the keying torque factor of butterfly valve matches, and volume is little, simple in structure, in light weight, adopt the integrated structure, shell protection is good, and Installation and Debugging are convenient.
The technological scheme that its technical problem that solves the utility model adopts is: part turning valve electro-hydraulic device, form by motor, support, oil pump, hydraulic manifold block, oil hydraulic cylinder, rotating shaft, key, stroke limit mechanism etc., motor links by support and coupling and oil pump, hydraulic manifold block and oil pump link, and oil pump is a two-way oil pump.Oil inlet and outlet joins on oil pipe and the oil hydraulic cylinder, and shift fork and turning axle are by key connecting, and piston is installed in the oil hydraulic cylinder, and piston and oil hydraulic cylinder are by seal with O ring, and slide block is installed on the axle that connects piston, and cooperates with the guiding groove of shift fork.A pair of position limit switch is installed on oil hydraulic cylinder, is carried out the stroke protection in unlatching and closed position.Driven by motor oil pump rotation during startup, the high-voltage oil liquid that produces is by the piston reciprocates of hydraulic manifold block, oil pipe control oil hydraulic cylinder, the slide block that links with piston slides in the guiding groove of shift fork, and shift fork wraparound shaft axis is swung, thereby realizes the keying of valve.
The beneficial effects of the utility model are that output torque is big, suitable drive unit as heavy caliber ball valve, butterfly valve, and volume is little, simple in structure, in light weight, adopts the integrated structure, and shell protection is good, and Installation and Debugging are convenient.
