Under the conditions of at the scene, when electric operator is out of service, because valve pressure is excessive, actuator can be made to send out Raw reversion, electric operator of the present utility model is designed with braking mechanism, as shown in figure 3, can effectively prevent from inverting, braking machine Structure mainly comprises：Travelling gear 15, shaft gear 19, brake 23, Brake Block 25, steel ball 17, spring press-cover 21, compression spring 22nd, flat key 20, shaft gear frame 18 etc., braking mechanism is fixed on installing plate 12, by screw 24 by shaft gear frame 18, installing plate 12nd, Brake Block 25 is screwed together, and shaft gear frame 18 is simultaneously used for fixing shaft gear 19.Biography on motor gear and braking mechanism Moving gear 15 engages, and when electric operator runs, motor gear band nutating gear 15 rotates, travelling gear 15 and axle tooth Wheel 19 is coaxial, and is coordinated by deep groove ball bearing 16 with Brake Block 25, because the mating surface of brake 23 and steel ball 17 is V-type Slot structure, Brake Block 25 is similarly V-groove structure with the mating surface of steel ball 17, while therefore travelling gear 15 rotates, can lead to Crossing steel ball 17 forces brake 23 to overcome the pressure of compression spring 22 to move up and rotate, and brake 23 is carried by flat key 20 Moving axis gear 19 rotates, because there are spring press-cover 21 and compression spring 22 in the top of brake 23, therefore in travelling gear 15 not During rotation, brake 23 is fitted tightly all the time with the taper surface of Brake Block 25, and frictional force is larger.When electric operator stops fortune The moment of torsion of one reversion of electric operator during row, because valve pressure is excessive, can be applied to, when this moment of torsion is delivered to axle tooth When taking turns 19, shaft gear 19 delivers torque to brake 23 by flat key 20, due to the taper surface of brake 23 and Brake Block 25 Remain and fit tightly, frictional force is big.The generation of electric operator reversion can effectively be prevented, then prevent butterfly valve, air door Etc. being rushed to open.

Fig. 4 is electric operator deceleration box installation diagram, and when motor 10 runs, motor gear drives in braking mechanism Travelling gear 15 rotates, and travelling gear 15 finally drives shaft gear 19 to rotate, and shaft gear 19 drives horizontal gear 27 to rotate, due to flat The internal tooth of gear 27 is engaged with the external tooth of centre wheel 30, and when horizontal gear 27 rotates, centre wheel 30 equally follows rotation, centre wheel 30 With planetary gear 28 and gear ring worm gear 33 and planet carrier 32, constitute a planetary gear set, planetary gear 28 passes through planet wheel spindle In 26 fixing planet carriers 32, because gear ring worm gear 33 is fixed by worm screw 35, Worm Wheel System has self-locking performance, can achieve anti- To self-locking, gear ring worm gear 33 can only be driven by worm screw 35, and worm screw 35 can not be driven by gear ring worm gear 33, in 30 turns of centre wheel While dynamic, planetary gear 28 can be driven to rotate, planet carrier 32 also can be to be rotated at a slow speed.Planetary gear 28 drives 34 turns of internal gear Dynamic.Moment is exported interface by internal gear 34, is connected with valve rod by actuating sleeve.

Fig. 5 overlooks installation diagram for electric operator deceleration box, passes through to shake handwheel 40 during manual operation, and handwheel 40 will Moment passes to manual shaft 38, and manual shaft 38 is connected by flat key 37 with worm screw 35, and worm screw 35 is followed manual shaft 38 and rotates, then leads to Cross worm screw 35 driven gear ring worm gear 33 to rotate.Gear ring worm gear 33 drives planetary gear 28, planet carrier 32, internal gear 34 to do synchronous rotation Turn, output interface is passed torque to by the rotation of internal gear 34, final control valve.The manual operation of present embodiment passes Motivation structure stable drive, safe and reliable, laborsaving.Manual/electric operation need not switch, and directly rotates handwheel during manual operation Can.Under motoring condition, in motor operation, handwheel will not follow rotation.

Valve position signal detects, joining work as shown in Figure 4 on internal gear 34 has a splined shaft 31, and splined shaft 31 is followed Internal gear 34 rotates, and splined shaft 31 top is connected with the spline gear 29 being assemblied on installing plate 12, spline connection mode, thus Spline gear 29 is driven to rotate, simultaneously equipped with potentiometer on installing plate 12, potentiometer is engaged with spline gear also by gear. Potentiometer resistance changes in the running to make electric operator by this kind of connected mode.Adjusted by control unit Whole and demarcate, can according to the resistance of potentiometer determine valve be located position.

Plug-in double containment wiring construction of the present utility model, overcome traditional actuator wiring safeguard inconvenient, Sealing is poor, and extraneous air easily corrodes these defects of box house, be respectively arranged with O-ring seal at patchboard two ends it is ensured that With dual-seal in rosette in control chamber body, do not interfere with each other, though pull down connector cover at the scene rewiring when, also will not Impact controls the sealing of box house, and binding post adopts connector to connect, and disconnects line very convenient.

Electric operator of the present utility model is provided with force moment protection function, in the handss at electric operator worm screw 35 two ends The disk spring 39 of equivalent is provided with moving axis 38, the load of butterfly spring 39 and deflection calculate through accurate, work as valve During bite, moment can be gradually increased, and gear ring worm gear 33 can be made to rotate, and then makes worm screw 35 that axial float, dish-shaped bullet to occur Spring 39 is compressed, and deflection is gradually increased, and the arm shaft due to installing moment rotating assembly 36 on a mounting board is embedded in all the time Worm screw 35 recessed grain in, moment rotating shaft can be made to rotate, corner is gradually increased, when valve moment increase to actuator When crossing force moment protection value, moment shaft rotary corner can be made to reach maximum, the magnet steel above now moment rotating shaft can trigger moment plate 11, Moment plate 11 sends intelligent control unit 3 to by crossing torque signals, and intelligent control unit 3 cuts off the power supply of motor 10 and showed Moment is reported to the police.

As shown in Figure 6 the LCD display 42 with backlight can clearly show valve location, valve state, operator scheme with And warning message etc., these display informations all can be checked through form 44, simultaneous with green, yellow, red three LED instruction Lamp 43 is used for indicating valve terminal location and fault alarm, also can be checked through form.Electric operator the machine button 45 are used for electric operating on the spot, and that is, non-intrusion type sets, and does not stretch into the insertion axle within actuator case lid, pushes button 45, the compression spring 47 of button 45 lower section is compressed, when button 45 is pressed to bottom, positioned at magnet steel 46 meeting of button 45 bottom Hall element on the PCB operation panel 41 of triggering actuator enclosure interior, instruction is then delivered to intelligent control unit.
