Abstract
The utility model relates to a valve electric actuator, which comprises a shell, a motor, a deceleration mechanism, a control box, a control circuit board mechanism, a display screen, a moment transducer component, a patching panel and an end shield. The deceleration mechanism consists of a worm wheel-worm mechanism; a worm is installed inside the shell via a bearing; a worm wheel is fixed on a principal axle; the moment transducer component is installed on the external side of the worm; the worm and the rotor axis of the motor are connected with each other via a pin shaft; the worm can move along the axial direction on the rotor axis of the motor. When the worm move to the left or right, the rotor of the motor keep unchanged, which resolves the problem of magnetic field loss resulted from the movement of the rotor of motor brought by the worm in prior art as well as realize the advantages of little power loss and high transmission efficiency. Besides, because the display screen consists of an upper part and a lower part that respectively displays the actual valve position and the target valve position, the display is direct and obvious. Therefore, the utility model can be applied to the openness regulating and control device of various valves.
Description
Technical field
The utility model relates to the electric actuator that a kind of control valve opens and closes.
Background technique
In the prior art, adopt the intelligent electric activator product of microprocessor technical control and regulation valve a lot, its structure generally comprises motor, the digital operator that shows of band, reducing gear, position feedback mechanism, function translator, torque transducer etc., it can realize the Flow characteristics correction of various valves, and can carry out online detection, diagnosis, malfunction alarm to the working condition of electric actuator.Reducing gear is made up of worm gear, worm transmission structure, worm screw and motor reel are structure as a whole or are fixedly connected on the motor rotary shaft, fixed installation torque transducer assembly on worm screw, in transmission process, worm screw produces axial displacement makes torque transducer produce torque signals.Subject matter is: will drive motor rotor during worm screw axial displacement simultaneously and produce displacement, and make between motor rotor and the stator to be subjected to displacement, and the motor effective magnetic field be diminished, the loss power of electric motor.Same output torque, institute's distribution motivation rated power will increase the motor inefficiency.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, and the intelligent electric activator that a kind of motor power (output) loss is little, transmission efficiency is high is provided.
The technical solution of the utility model comprises housing, motor, reducing gear, control box, control circuit board mechanism, display screen, the torque transducer assembly, patchboard, end cap, motor, control box, control circuit board mechanism, end cap respectively by screw on housing, patchboard is fixedly mounted on the housing, each tenminal block on the patchboard is respectively by conducting wire and motor power guide line, the power supply of control circuit board mechanism and control signal end connect, reducing gear is made up of worm gear-endless screw mechanism, worm screw by Bearing Installation in housing, worm gear is fixed on the main shaft, the torque transducer assembly is installed on the worm screw outside, mainly be to interconnect by pin between worm screw and the motor rotary shaft, and on motor rotary shaft, can move axially.
In above technological scheme, display screen is made up of physical location display screen and target location display screen two-part.
In the technique scheme, patchboard and tenminal block are by an injection-compression molding.
The utility model has the advantages that: worm screw and motor rotary shaft are that two discrete parts axially flexibly connect by assembling set, the invariant position of motor rotor during the worm screw move left and right, solved prior art and produced the magnetic field loss because of worm screw drive motor rotor moves, its power loss is little, transmission efficiency is high.In addition, display screen adopts two-part composition up and down, shows actual valve position and target valve position respectively, and is simple and clear.
