Abstract
A Z series valve electric executing mechanism comprising an electric control mechanism, a handle control mechanism, a shifter for handle control and electric control, an output mechanism, a motion control mechanism, a torque control mechanism and a position indication mechanism is characterized in that: the handle control mechanism is provided with a three-step gear pair reducing mechanism comprising a first-step bevel gear pair, a second-step spur gear pair and a third-step worm gear pair shared with an electric output mechanism, wherein, the first-step bevel gear pair driven by a hand wheel through a hand wheel shaft. The utility model which is applicable for valves with great moment and similar equipments can provide easy manual operation.
Description
Technical field:
The utility model relates to electric valve executing mechanism, the Z series of valves electric actuator of more specifically saying so and having manual control function.
Background technique:
Electric valve executing mechanism is to utilize manual and electric to carry out two formulas of open and close to turn round mode of operation more, can directly be used in valve rods such as gate valve, stop valve and make multi-turn revolution or straight-line valve and other similar devices, also can be used in turning valves such as dish valve, ball valve with the isostructural gear box combination of worm and gear.But in existing structural type, the speed ratio of man-operated mechanism generally is 1: 1 or too small, for the electric actuator that is applied on the big moment valve, shakes motionless when manually opened valve especially painstakingly or at all.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology deficiency, the Z series of valves electric actuator of manually-operable light and flexible being provided.
The technological scheme that the utility model technical solution problem is adopted is:
Structural feature of the present utility model is that the secondary reducing gear of manual control tertiary gear is set, and comprises one-level bevel gear pair, secondary commutating tooth wheel set and three grades of worm couples shared with motor, and described one-level bevel gear is driven by hand wheel shaft by handwheel.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, in the utility model man-operated mechanism tertiary gear secondary slow down free and relaxed when making under installation, debugging or the state of emergency manually operated valve.
2, the utility model is simple in structure, easy to implement.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is that Fig. 1 A-A is to view.
Number in the figure: 1 electric control mechanism, 2 manual control mechanisms, the moving switching mechanism of 3 torch, 4 output mechanisms, 5 range controlling mechanisms, 6 torque controling mechanisms, 7 position indicating devices, 8 handwheels, 9 hand wheel shafts, 10 housings, 11 bevel pinions, 12 bevel gear wheels, 13 small gears, 14 gearwheels, 15 splined shafts, 16 hollow worm screws, 17 tooth embedding worm gears, 18 clutches.
Below by embodiment the utility model is further described:
Embodiment:
Referring to Fig. 1, comprise electric control mechanism 1, manual control mechanism 2, the moving switching mechanism 3 of torch, output in the present embodiment
Mechanism 4, range controlling mechanism 5, torque controling mechanism 6 and position indicating device 7.
Referring to Fig. 2, in the present embodiment be, the secondary reducing gear of manual control tertiary gear is set, comprise one-level bevel gear pair, secondary commutating tooth wheel set and three grades of worm couples shared with motor to what prior art made improvements, wherein, the one-level bevel gear is driven by hand wheel shaft by handwheel.
In concrete the enforcement, as shown in Figure 2, handwheel 8 is installed in the outer end of hand wheel shaft 9, and be positioned at the outside of electric actuator housing 10, connect with flat key, bevel pinion 11 is contained in the other end of hand wheel shaft 9, and be meshed with bevel gear wheel 12 in being contained in gear cavity, small gear 13 in the commutating tooth wheel set of the second level is coaxial with bevel gear wheel 12, and fixedly connected with flat key, be connected for the gap between the small gear 13 and gearwheel 14 engagements that are contained in the band tooth embedding on the splined shaft 15, splined shaft 15 and the gearwheel 14 of being with the tooth embedding, hollow worm screw 16 is contained on the splined shaft 15, be meshed with band tooth embedding worm gear 17, band tooth embedding worm gear 17 is connected with being with the 4 tooth embeddings of tooth embedding output mechanism, and hollow worm screw 16 and splined shaft 15 are connected by spline, clutch 18 is contained on the splined shaft 15, and clutch 18 and splined shaft 15 are connected by spline.
When clutch 18 meshes with gearwheel 14, form dead axle system between gearwheel 14 and splined shaft 15 and the worm screw 16 and rotate synchronously, thereby the driving output mechanism rotates.Adopt said structure, required reduction speed ratio can be set very easily, the steering force during with change manual drives valve.
