nullIf Fig. 1 is front view of the present utility model，Fig. 2 is upward view of the present utility model，Safety valve door actuators，Including motor 1、Gear 1、Gear 23、Worm shaft 1、Worm gear 1、Worm shaft 26、Worm gear 27、Planetary gear 1、Planetary gear 29、Planetary gear 3 10、Sun gear 11、Planet carrier 13、Gear 3 14、Gear 4 15、Travelling nut 16、Encoder 17、Gear 5 18、Gear 6 19、Output shaft 20、Thread wheel case 21、Gear shaft 22、Butterfly spring 23、Worm shaft 3 24、Worm gear 3 25、External thread sleeve 26 and power transmission shaft 27，Motor 1 is connected with gear 23 by gear 1，Gear 23 and worm shaft 1 key connect，Worm gear 1 is connected with worm shaft 26 key，Worm shaft 26 is meshing mutually with worm gear 27，Worm gear 27 ring gear and planetary gear 1、Planetary gear 29 is mutually meshing with planetary gear 3 10，Sun gear 11 respectively with planetary gear 1、Planetary gear 29 is mutually meshing with planetary gear 3 10，Planet carrier 13 upper end and planetary gear 1、Planetary gear 29 and planetary gear 3 10 are rotationally connected，Fix with gear 3 14 bottom planet carrier 13 and be connected，Gear 4 15 and butterfly spring 23 are set on power transmission shaft 27，Threaded with thread wheel case 21 in travelling nut 16 upper end，Lower end and external thread sleeve 26 are interlocked，Thread wheel case 21 side is provided with gear shaft 22，Power transmission shaft 27 top is provided with encoder 17，Tail end is provided with gear 5 18，Gear 6 19 is mutually meshing with gear 5 18 and worm gear 3 25 respectively，Gear 6 19 is connected with output shaft 20，Worm shaft 3 24 matches with worm gear 3 25，Planet carrier 13 is connected by screw 12 is fixing with gear 3 14.
This utility model realizes remote auto control valve spool position and on-site manual quickly adjusts 2 critical functions of valve spool of valve position and automatic mode and manual mode can carry out and easy and simple to handle simultaneously.Device has overload and automatically disengages the unique function realizing protection automatically.Device can realize input torque is carried out the amplification of 150～200 times.
The drive path of remote auto pattern is: motor 1 is by the revolution of gear 1 driven gear 23, worm shaft 1 and gear 23 form entirety by key connected mode, worm shaft 1 drives worm gear 1 revolution to realize the primary speed-down of device, worm gear 1 and worm shaft 26 form entirety by key connected mode, and worm shaft 26 drives worm gear 27 revolution to realize the double reduction of device.Worm gear 27 is the gear ring in planetary gear speed reducing mechanism simultaneously, worm gear 27 rotates the ring gear against rotation being planetary gear speed reducing mechanism and drives planetary gear 28, planetary gear 39 and sun gear 10 to rotate, planetary gear 28, planetary gear 39 and sun gear 10 rotate around fixed sun gear 11, the rotation of planetary gear 28, planetary gear 39 and sun gear 10 drives planet carrier 13 to rotate simultaneously, it is achieved three grades of decelerations of device.Planet carrier 13 is rotated by gear clutch and screw 12 driven gear 3 14.Gear 3 14 driven gear 4 15 rotates, and gear 4 15 makes the roller ball type clutch between power transmission shaft 27 form frictional force under the effect of butterfly spring 23, it is achieved deliver torque to power transmission shaft 27.Power transmission shaft 27 upper end, is co-axially mounted encoder 17 and realizes record and the feedback of angle rotary size.Clutch shaft 27 lower end is co-axially mounted gear 5 18, and gear 5 18 driven gear 6 19 rotates.Gear 6 19 drives the output shaft 20 being coaxial therewith to turn round, it is achieved power exports.
The drive path of manual adjustment mode is: manual adjustments worm shaft 3 24 rotates, and drives worm gear 3 25 to rotate.Worm gear 3 25 drives the sun gear 11 that is coaxial therewith to rotate, and the gear ring that now worm gear 27 maintains static in both planetary gear speed reducing mechanisms is fixed, planetary gear and sun gear motion.Sun gear 11 rotates and drives planetary gear 28, planetary gear 39 and sun gear 10 and planet carrier 13 to rotate simultaneously.Planet carrier 13 is rotated by gear clutch and screw 12 driven gear 3 14.Gear 3 14 driven gear 4 15 rotates, and gear 4 15 makes the roller ball type clutch between power transmission shaft 27 form frictional force under the effect of butterfly spring 23, it is achieved deliver torque to power transmission shaft 27.Power transmission shaft 27 lower end is co-axially mounted gear 5 18, and gear 5 18 driven gear 6 19 rotates.Gear 6 19 drives the output shaft 20 being coaxial therewith to turn round, it is achieved the adjustment to output shaft 20 angle.
Overload protection and elimination: when the moment of torsion that output shaft 20 under automatic mode exports is not enough to open valve, gear 5 18, gear 6 19 and power transmission shaft 27 cannot work.Now gear 3 14 delivers torque to gear 4 15, and the frictional force of the ball clutch between gear 4 15 and power transmission shaft 27 is less than the moment of torsion needed for rotating drive shaft 27 so that produce relative rotation between gear 4 15 and power transmission shaft 27.Now gear 4 15 is surely opened butterfly spring 23 and is produced skidding, it is achieved overload protection.Overload eliminate, turning gear wheel shaft 22, drive thread wheel case 21 rotate, thread wheel case 21 drive external thread sleeve 26 move compression butterfly spring 23 the ball frictional force between gear 4 15 and power transmission shaft 27 is increased.Overload protection just can be eliminated again through manual adjustments.
