Abstract
The utility model discloses a driving device for an electronic control valve, which comprises a motor and a driven gear shaft arranged on a valve body support, and a driving gear and a baffle plate are respectively and fixedly installed on both ends of a motor output shaft; a transmission gear is sheathed in the middle of the motor output shaft, one end of the transmission gear is meshed with the driving gear as a saw-tooth gear, the other end of the transmission gear is meshed with the driven gear shaft as a straight-tooth cylindrical gear, and a spring is arranged between the transmission gear and the baffle plate; and one end of the driven gear shaft is provided with a manual knob, and the other end of the driven gear shaft is provided with an eccentric bulge connected with a piston connecting rod.
Description
Technical field
The utility model relates to a kind of drive unit of electronic control valve.
Background technique
The running of existing electronic type control valve can only be controlled by the pcb board drive motor, in case need not have electricity operation or operation then can not realize fast.And because the restriction and the requirement of products of electronic control valve self, running speed can not infinitely promote, and a lot of users are slowly very dissatisfied to electronic type control valve motion speed when debugging.
Summary of the invention
Goal of the invention: the purpose of the utility model provides a kind of possess electronic and manual two kinds of driving mode, the drive unit of the electronic control valve of can realize quick unlatching, closing.
In order to solve the problems of the technologies described above, the utility model has adopted following technological scheme:
A kind of drive unit of electronic control valve; It comprises motor and the driven gear shaft that is arranged on the valve body support; Two ends at motor output shaft fixedly mount actuation gear and baffle plate respectively, and the slip socket driving gear at the middle part of motor output shaft, an end of driving gear and actuation gear are the sawing shape gear engagement; The other end of driving gear and driven gear shaft are the straight toothed spur gear engagement, between driving gear and baffle plate, spring are set; One end of driven gear shaft is provided with hand knob, and the other end of driven gear shaft is provided with the eccentric boss that connects piston rod.
Beneficial effect: the electronic control valve drive of the utility model possesses electronic and manual two kinds of driving mode, when control valve detects or debugs, can realize fast opening and closing, also can manually move during power failure, guarantees to produce normal operation; The utility model operation simple in structure, easy for installation, easy.
Description of drawings
Fig. 1 is shown the structural representation of the utility model.
Fig. 2 is the gear engagement schematic representation of driving gear.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done explanation further.
As illustrated in fig. 1 and 2, the drive unit of the electronic control valve of the utility model comprises motor 2, driven gear shaft 3, actuation gear 4, baffle plate 5, driving gear 6, spring 7 and hand knob 8.
Motor 2 is installed on the valve body support 1 with driven gear shaft 3.Actuation gear 4 and baffle plate 5 are fixedly mounted on the two ends of motor 2 output shafts respectively, and driving gear 6 is in the slip socket of the middle part of motor 2 output shafts.One end of driving gear 6 and actuation gear 4 are the sawing shape gear engagement, and the other end of driving gear 6 and driven gear shaft 3 are the straight toothed spur gear engagement.Spring 7 is arranged between driving gear 6 and the baffle plate 5.Hand knob 8 is arranged on an end of movable gear shaft 3, and the other end of driven gear shaft 3 is provided with the eccentric boss 9 that connects piston rod.
The motorized motions state of this device is: motor 2 drives actuation gear 4 and rotates; Driving gear 6 is pressed on the actuation gear 4 and its engagement by spring 7; Actuation gear 4 drives driving gear 6 and rotates; Driving gear 6 and then drive driven gear shaft 3 rotate, and eccentric boss 9 rotations on the movable gear shaft 3 drive piston rods and move up and down, and then realize the keying function of control valve.
The manual drives state of this device is: can drive driven gear shaft 3 through operation hand knob 8 and rotate; Eccentric boss 9 rotations on the movable gear shaft 3 drive piston rod and move up and down; And then the keying function of realization control valve, hand knob 8 rotates fast more, and the opening and closing time of control valve is short more.Because during manually-operable, the speed that driving gear 6 rotates is than actuation gear 4 moving blocks, driving gear 6 can be held pressure spring 7 in 4 minutes along saw shape tooth inclined-plane and actuation gear.Under manual state, the sense of rotation of hand knob 8 need with the direction of rotation of motor 2 output shafts, if rotation direction is identical, then driving gear 6 can be blocked by the saw shape teeth groove of actuation gear 4, can't separate with actuation gear 4.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
