Abstract
The utility model relates to a valve electric actuating mechanism which belongs to the technical field of valve control. The utility model is composed of a motor, Hall elements, a magnetic loop, a transmission mechanism and a data processing system, and is characterized in that one end of a worm and an output shaft of the transmission mechanism is provided with the magnetic loop and the Hall element. The rotation of the motor drives the transmission mechanism to rotate, the worm and the output shaft of the transmission mechanism drive the magnetic loop to induct the Hall element to produce pulse signals, and the pulse signals are transmitted to the data processing system to measure out a travel range of the valve electric actuating mechanism. The magnetic loop can rotate, the magnetic loop does not contact the Hall element, and thus the abrasion between components can not lead to reducing measurement precision. Two Hall elements simultaneously measure to improve the reliability of the measurement; the utility model makes the measurement precision reach a new level on the original basis by a speed transformation ratio.
Description
Technical field
The utility model relates to a kind of electric valve executing mechanism, belongs to technical field of valve control.
Background technique
The stroke of electric valve executing mechanism (or electric device for valve) and torgue measurement at present all is to adopt the Mechanical Contact formula, and not only measuring accuracy is not high, and along with the prolongation of service time, mechanical wear can make measuring accuracy progressively reduce.By retrieval, application number is 01224760 intelligent valve Electric actuator, in the motor special component internal, comprise a code-disc that rotates synchronously with electric machine main shaft, cylindrical magnetic iron signal source, Hall switch Detecting element along the circumferential direction evenly are set on the code-disc, by lead they are connected in the control module circuit, the deficiency of this technological scheme is that code-disc and cylindrical magnetic iron signal source and Hall switch Detecting element are arranged on the electric machine main shaft, thereby measured moment of torsion with control is the working condition of motor, rather than the practical working situation of output shaft.The stroke, the torque measuring device that change so must design that a kind of measuring accuracy height and precision can not passed in time.
Summary of the invention
The purpose of this utility model is the deficiency at above-mentioned Mechanical Contact formula electric valve executing mechanism (electric device for valve) and the existence of intelligent valve Electric actuator, the measuring accuracy height is provided, and it is never wornout, how long no matter use measuring accuracy on all four a kind of electric valve executing mechanism when dispatching from the factory.
The purpose of this utility model is achieved through the following technical solutions, a kind of electric valve executing mechanism, comprise motor, Hall element, magnet ring, driving mechanism, data processing system, it is characterized in that magnet ring is arranged on an end of driving mechanism worm screw and output shaft, the corresponding magnet ring setting of Hall element.
The utility model is provided with magnet ring and Hall element driving mechanism worm screw and output shaft one end, the rotation of motor drives driving mechanism and rotates, the worm screw of driving mechanism and output shaft drive magnet ring induction Hall element and produce pulse signal, be transferred to data processing system, measure the stroke of electric valve executing mechanism, magnet ring is rotatable, not contact between magnet ring and the Hall element, thereby guaranteed can not cause between the components and parts reduction of measuring accuracy because of wearing and tearing, two cover Hall elements are measured simultaneously, open the raising measuring reliability, the utility model has improved one-level to measuring accuracy by the speed no-load voltage ratio on original basis.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure, 1 magnet ring, 2 Hall elements, 3 data processing systems, 4 Hall elements, 5 magnet rings, 6 worm gears, 7 worm screws, 8 motors, 9 output shafts.
Embodiment
Further specify the utility model in conjunction with the accompanying drawings and embodiments, the utility model is by magnet ring 1,5, Hall element 2,4, and data processing system 3, worm gear 6, worm screw 7, motor 8 and output shaft 9 constitute.The rotating shaft of motor 8 connects worm screw 7, and the rotation of worm screw 7 drives magnet ring 5 and rotates, the rotation of Hall element 4 reaction magnetic rings 5, and Hall element 4 produces pulse signal, is transferred to data processing system 3; Worm screw 7 spins with worm gear 6 simultaneously, and worm gear 6 is connected with output shaft 9 again, rotates thereby drive output shaft 9, the rotation of output shaft 9 drives magnet ring 1 and rotates, the rotation of Hall element 2 reaction magnetic rings 1, and Hall element 2 produces pulse signal, be transferred to data processing system 3, finish the measurement of stroke.The S of magnet ring 1,5, N interpolar are every setting; Gapped between magnet ring 1,5 and the Hall element 2,4.
Claims (4)
1, a kind of electric valve executing mechanism comprises motor, Hall element, magnet ring, driving mechanism, data processing system, it is characterized in that magnet ring is arranged on an end of driving mechanism worm screw and output shaft, the corresponding magnet ring setting of Hall element.
