Abstract
The utility model discloses a valve electric actuator flashlight moves switching structure, including hand wheel, association, output shaft, worm, worm wheel, clutch, switching handle with switch the axle, it still includes lifting plate and lifting plate axle its characterized in that, lifting plate's one end and lifting plate axle clearance fit, lifting plate's the other end sticiss in the one end of switching the handle, and lifting plate can rotate around the lifting plate axle, lifting plate and clutch clearance fit. The superiority: because the utility model adopts the above structure, increase the one -level lever mechanism in other words and come the reinforcement, make the power of lifting plate when promoting the clutch increase, make that the clutch is easier to break away from with the worm wheel, it is easier that messenger's flashlight moves the switching, and to a great extent has increased the reliability that the flashlight moved the switching.
Description
(1) technical field:
The utility model relates to electric device for valve technical field, particularly a kind of electric device for valve hand-electric switching construction.
(2) background technique:
At present, electric device for valve be a kind of with valve with the use of, the electromechanical integration industry equipment that control valve opens and closes.When scene needs manually-operable electric device for valve, must ensure that hand-electric switching construction is safe and reliable.
Electric device for valve hand-electric in known technology switches to shown in Fig. 1, worm screw 3 is driven by motor and drives worm gear 5 to rotate, worm gear 5 is keeping dental inlay to be connected with while output shaft 4 Spielpassung with clutch 6 and is being with dynamic clutch 6 to rotate under motoring condition, clutch 6 and output shaft 4 spline joint can drive output shaft 4 to rotate and then drive the switch of valve, and clutch 6 can be slided up and down by spline on output shaft 4, when scene needs manually-operable electric device for valve, press by shown by arrow direction and switch handle 7, switching handle 7 with switching shaft 8 is Spielpassung, while pressing switching handle 7, switch handle 7 clutch 6 is lifted, make it to depart from the connection of worm gear 5 and form dental inlay with combination 2 and be connected, combination 2 with handwheel 1 for singly-bound is connected, now drive handwheel 1 can rotate and then drive the switch of valve by Direct driver output shaft 4.
But there is following shortcoming in this structure:
When valve occurs that stuck state needs manually-operable, larger torque is there is between output shaft 4 and clutch 6, dental inlay has very large frictional force between connecting, it is larger that now operation switches switching power needed for handle 7, likely there is the phenomenon of " switching motionless ", have a strong impact on valve electric drive scene behaviour in service.
(3) model utility content:
The purpose of this utility model is to provide a kind of electric device for valve hand-electric switching construction, and it can increase switching power, improves the reliability of switching construction.
The technical solution of the utility model: a kind of electric device for valve hand-electric switching construction, comprise handwheel, combination, output shaft, worm screw, worm gear, clutch, switch handle and switching shaft, described worm screw is driven by motor and intermeshes with worm gear, described worm gear coordinates with output shaft clearance, described output shaft and clutch spline joint, described clutch is slided up and down by spline on output shaft, when clutch lifts, the upper end of clutch is connected with combination dental inlay, when clutch falls, the lower end of clutch is connected with worm gear dental inlay, described switching handle and switching shaft Spielpassung, described handwheel is connected with combination singly-bound, it is characterized in that it also comprises riser and riser axle, one end of described riser coordinates with riser shaft clearance, the other end of riser is pressed on the one end switching handle, riser can rotate around riser axle, riser coordinates with clutch play.
Working procedure of the present utility model: under motoring condition, motor drives output shaft rotation and then actuating valve gate switch by the transmission of worm gear, worm screw, during switching, switching handle is pressed downwards with hand, switch handle rotate around switching shaft and provoke riser, riser around riser axle rotation, and then on push away clutch, clutch and worm gear are departed from, and forms dental inlay with combination and be connected to form manual operation state.
The advantage that the utility model has and good effect are: because the utility model adopts the mode increasing riser and riser axle to improve switching construction, be equivalent to increase primary lever mechanism and carry out reinforcement, the power of riser when lifting clutch is increased, make clutch more easily and worm gear depart from, hand-electric is switched easier, add the reliability that hand-electric switches to a great extent.
(4) accompanying drawing illustrates:
Fig. 1 is known technology structural representation.
Fig. 2 is the structural representation that involved by the utility model, electric device for valve hand-electric switching construction is in motoring condition.
Fig. 3 is the structural representation that involved by the utility model, electric device for valve hand-electric switching construction is in manual mode.
Wherein, 1 is handwheel, and 2 is combination, and 3 is worm screw, and 4 is output shaft, and 5 is worm gear, and 6 is clutch, and 7 for switching handle, and 8 be switching shaft, and 9 be riser 10 is riser axle.
(5) embodiment:
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Embodiment: a kind of electric device for valve hand-electric switching construction (see Fig. 2-3), comprise handwheel 1, combination 2, output shaft 4, worm screw 3, worm gear 5, clutch 6, switch handle 7 and switching shaft 8, described worm screw 3 is driven by motor and intermeshes with worm gear 5, described worm gear 5 and output shaft 4 Spielpassung, described output shaft 4 and clutch 6 spline joint, described clutch 6 is slided up and down by spline on output shaft 4, when clutch 6 lifts, the upper end of clutch is connected with combination 2 dental inlay, when clutch 6 falls, the lower end of clutch 6 is connected with worm gear 5 dental inlay, described switching handle 7 and switching shaft 8 Spielpassung, described handwheel 1 is connected with combination 2 singly-bound, it is characterized in that it also comprises riser 9 and riser axle 10, one end of described riser 9 and riser axle 10 Spielpassung, the other end of riser 9 is pressed on the one end switching handle 7, riser 9 can rotate around riser axle 10, riser 9 and clutch 6 Spielpassung.
The working procedure of the present embodiment: under motoring condition, motor drives output shaft rotation and then actuating valve gate switch by the transmission of worm gear, worm screw, during switching, press downwards with hand and switch handle 7, switch handle 7 rotate around switching shaft 8 and provoke riser 9, riser 9 rotates around riser axle 10, so on push away clutch 6, clutch 6 and worm gear 5 are departed from, and forms dental inlay with combination 2 and be connected to form manual operation state.
