Abstract
The utility model relates to a valve control device, in particular to an aerodynamic and manual control device used for controlling valves of energy-saving and environmental-friendly equipment. An aerodynamic and manual control device includes a hand wheel, a gear, an inner gear, a worm, a worm wheel, a switch handle, a cam, a clutch, a spring and a main shaft; the hand wheel and gear are installed on the same shaft, the gear is meshed with the inner gear, the inner gear is disposed on the worm, the worm wheel is fit over the main shaft, the clutch is disposed on the main shaft by a slide key and supported on the cam, the worm wheel is connected with the worm, a circle of grooves is disposed on the side of the clutch and the cam is disposed in the groove and connected with the switch handle by a driving shaft. The utility model has the beneficial results that the principle and design is rational, structure is original and unique, the appearance is compact, the operation is convenient and the utility model can realize aerodynamic and manual control.
Description
Affiliated technical field
The utility model relates to a kind of valve control device, particularly relates to a kind of control gear of Pneumatic and manual of the valve control that is used for energy-conservation and environmental protection equipment.
Background technique
At present, use energy-saving equipment and environmental protection equipment along with advocating day by day, the using scope of valve Pneumatic actuator is more and more wider, but for a long time, Pneumatic actuator does not have manual operation function, is restricting it and is continuing development.The valve Pneumatic actuator complex structure that occurred on market in the past is awkward, and is easy to damage.A lot of users after use because of feeling to be inconvenient to abandon this device, therefore, in fact caused the valve Pneumatic actuator not have manually operated function, the utility model is well-designed in conjunction with domestic actual use condition, be mainly used in part turning valves such as opening and closing ball valve, butterfly valve, also can be separately and the supporting composition manually-operated gate of valve, can be widely used on the pipeline of industry such as oil, chemical industry, water power, coal, papermaking, food, light textile.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model proposes a kind of novel valve Pneumatic and manual device.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of valve Pneumatic and manual device, has handwheel, gear, internal gear, worm screw, worm gear, switch handle, cam, clutch, spring, main shaft, handwheel and gear are installed on the same axis, gear and internal gear engagement, internal gear is installed on the worm screw, the worm gear sky is enclosed within on the main shaft, clutch is contained on the main shaft by feather key, and prop up on cam, worm gear and worm screw are connected, also have a circle groove in the side of clutch, cam is arranged in the groove and by transmission shaft and is connected with the switching handle.
The beneficial effects of the utility model are, principle design is reasonable, the novel structure uniqueness, and compact appearance, easy to operate, can realize manually and pneumatic two kinds of state of a controls.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1, handwheel, 2, gear, 3, internal gear, 4, worm screw, 5, worm gear, 6, switch handle, 7, cam, 8, clutch, 9, spring, 10, main shaft.
Embodiment
Valve Pneumatic and manual device as shown in Figure 1, have handwheel 1, gear 2, internal gear 3, worm screw 4, worm gear 5, switch handle 6, cam 7, clutch 8, spring 9, main shaft 10, handwheel 1 and gear 2 are installed on the same axis, gear 2 and internal gear 3 engagements, internal gear 3 is installed on the worm screw 4, worm gear 5 skies are enclosed within on the main shaft 10, clutch 8 is contained on the main shaft 10 by feather key, and prop up on cam 7, worm gear 5 is connected with worm screw 4, also have a circle groove in the side of clutch 8, cam 7 is arranged in the groove and by transmission shaft and is connected with switching handle 6.Rotate and switch handle 6, cam 7 also rotates, and drives clutch 8 and slides on main shaft 10, during with the complete assembling of pneumatic valve, Pneumatic actuator is installed in the top of main shaft 10, and the output shaft on the Pneumatic actuator is connected with main shaft 10, valve is installed in the lower end of this device, and valve rod is connected with main shaft 10.When normal pneumatic operation, switch handle 6 and switch in pneumatic shelves, worm gear 5 is thrown off with the pawl of clutch 8, and when Pneumatic actuator moved, the output torque of Pneumatic actuator was passed to valve rod by main shaft 10, thereby realized pneumatic opening/shutting valve.When needs are manual, switching handle 6 switches to manual, to lower slider, clutch 8 is meshing with each other with the pawl of worm gear 5 clutch 8, rotates handwheel 1 then under the effect of spring 9, drive internal gear 3 by gear 2, drive worm screw 4 and rotate, worm gear 5 is given in worm screw 4 transmissions, and worm gear 5 is given clutch 8 by the pawl transmission, main shaft 10 is given in clutch 8 transmissions, thereby drives valve event.
