Abstract
The utility model provides an advantage makes this electronic jar can switch over under the outage condition to manual mode continuation work again, and switches over convenience, reliable and stable between electronic mode and the manual mode that flow control valve is with the structure of electronic jar, and it has increased a manual control mechanism on the basis of original electronic jar, kept the high accuracy of electronic jar promptly, the high reliability, it is convenient to safeguard.
Description
Technical field
The utility model belongs to a kind of modified node method of electric cylinder, for adjust flux adjuster valve valve port flow, and especially can with manually regulating with automatic two kinds of modes.
Background technology
At present, known electric cylinder structure is made up of servomotor, synchronous pulley, feed screw nut pair, piston rod, cylinder barrel etc., controls the thrust of electric cylinder, speed and displacement by controlling servomotor.But the electric cylinder of this form can quit work under the situation of power-off, causes flow control valve out of service.And in some particular job occasion, having the possibility of the power-off that meets accident, this just needs a kind of electric cylinder having electronic and manual two kinds of control modes.
Summary of the invention
Can only power-actuated deficiency in order to overcome existing electric cylinder, the utility model provides a kind of electric cylinder structure, and this electric cylinder can drive flow control valve to work on by handwheel in the event of a power failure.
The utility model solves the technical scheme that its technical problem adopts: increase a Coupling Shaft at electric cylinder screw mandrel tail end, Coupling Shaft reaches outside rear base plate, is connected with man-operating mechanism.Man-operating mechanism is made up of brake fixing seat, electromagnetic brake, dust cover, handwheel, is connected by screw into an entirety.Pulley cover is provided with index pin, and index pin coordinates with the index hole on brake fixing seat.Under electric cylinder is in Electronic control pattern, index pin is screwed in brake fixing seat index hole, makes man-operating mechanism static, does not follow electric cylinder motion.After electric cylinder power-off, brake bush contacts with main body, and man-operating mechanism is connected by parallel key with Coupling Shaft, index pin of now back-outing, and just can drive electric cylinder by rotating handwheel.
After electric cylinder, base plate is processed with cannelure, disc-type slide ring glue is bonded on rear base plate, is powered to electromagnetic brake by disc-type slide ring.
