The hand wheel is connected with the worm through a rotating shaft. The worm is opposite to the worm gear. Automatic control and manual control can be switched; and the actuator is convenient to use, and can be reliably arranged.
Description
Technical field
The utility model relates to the switch actuator technical field, particularly a kind of auto-manual Two purpose valve switch actuator.
Background technique
As everyone knows, valve is widely used in the pipe-line equipment to control the flow of fluid.The switch actuator of valve is divided into two kinds of recloser final controlling element and hand switch final controlling element.The recloser final controlling element exists easy to use, need not manually-operated advantage, but has complex structure simultaneously, and the deficiency that breaks down easily in case break down, will directly influence equipment pipe work.The hand switch final controlling element is then opposite, and is simple in structure, and rate of fault is low, but troublesome poeration.So development a kind of automatically with the valve switch final controlling element of dual-use manual, become the focus of studying in the industry.
The model utility content
The purpose of the utility model is defective and the deficiency to existing technology, and a kind of simple and compact for structure, auto-manual Two purpose valve switch actuator that control accuracy is high is provided.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
The described a kind of auto-manual Two purpose valve switch actuator of the utility model; Comprise handwheel, housing and clutch, said clutch comprise excentric sleeve and the worm screw of being located in the excentric sleeve; Be provided with worm gear in the said housing; Be arranged with coupling shaft in the said worm gear, said coupling shaft one end stretches out outside the housing, and the other end is connected with axle sleeve; Said handwheel is connected with worm screw through rotating shaft, and said worm and wheel becomes corresponding and is provided with.
Further, said rotating shaft one end is fixedly connected handwheel through spring pin, and the rotating shaft the other end passes the worm screw center hole, and is fixedly connected with worm screw through spring pin, is equipped with bearing unit in the rotating shaft at said worm screw two ends.
Further, said housing is formed by connecting bearing and lid.
Further, said excentric sleeve is provided with spanner.
After adopting said structure, the utility model beneficial effect is: said coupling shaft one end of the utility model stretches out outside the housing, and the other end is connected with axle sleeve; During use, with the utility model axle sleeve fixed valve running shaft, coupling shaft stretches out the outer end of housing and automatically performs device and be connected; When need automatically perform the device automatic switch valve; The excentric sleeve of rotary clutch makes worm and wheel separately, and valve is by automatically performing device control; When the need manual control valve, will automatically perform device control and separate with coupling shaft, the excentric sleeve of rotary clutch cooperates worm and wheel.The utility model can switch between controlling automatically and manually controlling each other, and is easy to use, arranges reliably.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Like Fig. 1, shown in Figure 2, the described a kind of auto-manual Two purpose valve switch actuator of the utility model comprises handwheel 6, housing and clutch, and said clutch is located on the housing.Also be handwheel 1, housing and clutch constitute the utility model integral outer structure.
Said clutch comprises excentric sleeve 12 and the worm screw of being located in the excentric sleeve 12 5, and said excentric sleeve 12 is provided with spanner 3, and spanner 3 is used for rotation adjustment excentric sleeve 12, thereby adjusts worm screw 5 positions indirectly.
Said handwheel 6 is connected with worm screw 5 through rotating shaft 4.Particularly, said rotating shaft 4 one ends are fixedly connected handwheel 6 through spring pin 10, and rotating shaft 4 the other ends pass worm screw 5 center holes, and are fixedly connected with worm screw 5 through spring pin 10, are equipped with bearing unit 11 in the rotating shaft 4 at the two ends of said worm screw 5.Bearing unit 11 mainly is convenient to rotating shaft 4 realization rotation smoothly.
Be provided with worm gear 9 in the said housing, be arranged with coupling shaft 1 in the said worm gear 9, promptly worm gear 9 can drive coupling shaft 1 rotation.Worm screw 5 and worm gear 9 vertical corresponding matching settings.
Said coupling shaft 1 one ends are connected with axle sleeve 8, and coupling shaft 1 the other end stretches out outside the housing.Said axle sleeve 8 is used to connect the fixed valve running shaft, and coupling shaft 1 stretches out the outer end of housing and is used for and automatically performs device and is connected, promptly automatically performs the switch that device can pass through coupling shaft 1 realization valve.
Said bearing unit 11 outsides can be provided with oil sealing, mainly play seal action.
Said housing is formed by connecting bearing 7 and lid 2, is provided with like this, is convenient to the installing/dismounting and the maintenance of worm gear 9 in the housing.
Working principle:
When needing with the utility model autocontrol valve gate switch; The axle sleeve 8 of being located at coupling shaft 1 one ends is fixedly connected the valve running shaft; Coupling shaft 1 stretches out the outer end connection of housing and automatically performs device, through spanner 3 rotation adjustment excentric sleeves 12 positions, makes worm screw 5 and worm gear 9 be in separated state; Like this, automatically perform directly control valve switch of device.
When needing, separate automatically performing device and coupling shaft 1, through spanner 3 rotation adjustment excentric sleeves 12 positions with the utility model hand control valve gate switch; Make worm screw 5 and worm gear 9 be in mated condition; Through rotation hand wheel 6, successively through rotating shaft 4, worm screw 5; Worm gear 9 and coupling shaft 1 drive the rotation of valve running shaft, realize that valve switch opens and closes.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
