Support 20 is carried out during blocking gas outlet 12, and combustion gas leaks at gas outlet 12.
The drive mechanism includes motor 31, gear-box 32, drive gear 33, driving leading screw 34 and drive nut 35, its
Described in gear-box 32 be reduction box, its input is connected with the rotating shaft of motor 31, output end be output gear 321 and with drive
Moving gear 33 is meshed, that is, realizes being sequentially connected for motor 31, gear-box 32 and drive gear 33, is driven with being driven with motor 31
Moving gear 33 is rotated.In addition, the driving leading screw 34 is specifically located on the center of circle line of drive gear 33, and and sliding tooth
The rotation connection of wheel 33, a thread segment 341 is provided with the driving leading screw 34, to be threadedly coupled with drive nut 35.
In the present embodiment, the drive gear 33 is provided with a stop on the side face of gear towards driving leading screw 34
Post 331, correspondingly, actuator is provided with the driving leading screw 34, and especially by the stop post 331 on drive gear 33 with
The abutting between the actuator on leading screw 34 is driven to coordinate, to realize that the drive gear 33 drives to the rotation for driving leading screw 34.
Specifically, a pilot hole 332 is offered on the center of circle line of the drive gear 33, to assemble sliding tooth leading screw 34,
And the stop post 331 is specifically provided in the peripheral of pilot hole 332, and the actuator is specially latch 36, described to insert
Pin 36 coordinates relative to the split type dismounting of driving leading screw 34.
Wherein, the latch 36 is specifically to be arranged in a manner of socket on driving leading screw 34, and the latch 36 is in face
A limited post 361 is provided with to the side inwall of driving leading screw 34, and the part of the limited post 361 stretches to drive screw 34
It is interior, and relative to 34 spacing fixation of drive screw, so it is achieved that latch 36 with driving leading screw 34 in radial directions
It is spacing, that is, latch 36 can drive driving leading screw 34 to be rotated while rotating.In addition, the latch 36 is away from driving
The side of screw mandrel 34 is outwards provided with a projection 362, and the projection 362 on the latch 36 and the stop post on drive gear 33
331 partly overlap setting, that is, drive gear 33, during rotation, the stop post 331 on drive gear 33 can touch slotting
Projection 362 on pin 36, and then realize rotation driving of the drive gear 33 to latch 36.
From the foregoing, it will be observed that the drive mechanism of the present embodiment is at work, motor 31 drives drive gear 33 by gear-box 32
While rotation, stop that post 331 carries out rotation until touching the projection on latch 36 one in company with drive gear 33
362, then drive latch 36 to be rotated, because latch 36 and driving leading screw 34 are spacing fixation in radial directions, this
Sample is achieved that function of the drive gear 33 to the driving driving rotation of leading screw 34, and drive nut 35 is to be threaded in driving silk
On the thread segment 341 of thick stick 34, such drive nut 35 will be on the driving leading screw 34 rotated in company with drive gear 33
Moved back and forth, and then realize the driving operation to support 20.
It is appreciated that drive nut 35 driving leading screw 34 on moved back and forth during, its drive nut 35 with
The cooperation of driving leading screw 34 needs to carry out spacing stall, occurs to prevent the motor valve 100 after high voltage carries out valve opening driving
From situation generation that is locked, and carrying out not closing valve at lower voltages during the valve of pass.Therefore, the driving leading screw 34 of the present embodiment exists
The lower section of thread segment 341 is provided with a boss 342, and correspondingly, pilot hole 332 will open up into cooperation and drive on the drive gear 33
The structure of 34 external shape of dynamic leading screw.And nut block 351 is provided with the drive nut 35, and especially by drive nut
The abutting between the boss 342 on nut block 351 and driving leading screw 34 on 35 coordinates, to realize driving leading screw 34 and driving
Axial limiting between nut 35.Further, the nut block 351 is set to integral structure, and institute with drive nut 35
The outer direction without leave away from drive nut 35 for stating nut block 351 is gradually reduced, in order to the assembling of other parts.
On the other hand, multiple convex portions 352 are provided with the outer peripheral face of the drive nut 35, with being offered on support 20
Groove 22 abut coordinate.Specifically, in the present embodiment, two are opened up in inverted "L" shaped the end symmetric of the support 20
Groove 22, and two convex portions 352 are correspondingly provided with the outer peripheral face of drive nut 35, so not only can be by the driving spiral shell
Mother 35 is driving the progress in the radial direction of leading screw 34 mutually spacing with support 20, and can be with the drive nut 35 towards wherein one
Individual direction is driven to support 20；Further, since the drive nut 35 also carries out abutting cooperation with the end of support 20 so that
The drive nut 35 can be driven towards another direction to support 20, and then realize the drive nut 35 along driving leading screw
34 axial direction is to the bi-directional drive of support 20.
So the drive mechanism at work, by motor 31 the specific rotation for controlling driving leading screw 34, and utilizes driving
Being threadedly coupled to drive drive nut 35 to do moving back and forth relative to driving leading screw 34 between leading screw 34 and drive nut 35,
And then driving arm 20 does moving back and forth relative to gas outlet 12.That is, the motor valve 100 is when in use, by motor
31 control, so that it may realize the control closed logical to gas outlet 12 on the valve body 10, and then realize the motor valve 100 is opened or
The control that person closes.
In summary, motor valve of the present utility model, driving is driven by stopping the structure setting of post on drive gear
