For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of many device for revolving and driving of valve control usefulness, comprise motor 11, main box body 6, reducing gear, range controlling mechanism and long cable section of ingoing line sealing mechanism,
Said reducing gear comprise the worm shaft 9 that in bearing support 13, is connected with motor shaft 12 through key, with the worm gear 2 and the live axle that passes worm gear 2 and be connected 1 of worm shaft 9 Vertical Meshing;
Said range controlling mechanism comprises the stroke cover 3 that is connected with live axle 1 one ends, be through the stroke levers combination 4 of installing in the stroke cover 3, make up counter that 4 one ends are connected with the stroke lever that stretches out the stroke lever cover casing outside makes up 5 and make up 5 explosion-proof travel switch 8 that install with counter;
Said long cable section of ingoing line sealing mechanism is made up of the inlet wire cover 17 that baffle plate 15, sealing plug 19, packing ring 16 and gland nut 18 are housed in it successively;
Said main box body 6 is fixedly connected with bearing support 13, is fixed with control box cover 7 through concavo-convex seam on the main box body 6;
Said worm shaft 9 the other ends expose to main box body 6 sides, only are useful on interior six sides of the moving handle 14 of connection hand on its end.
Advantage and good effect that the present invention has are: owing to adopt technique scheme, strengthened the assembling intensity of main box body 6 with control box cover 7, made its junction plane possess the explosion-proof criteria requirement, improved the Security of operation; Reducing gear is one-level bull worm gear 2 auxiliary structures, has high output speed and can reach 70r/min; The permanent protective property that has guaranteed drive unit can; Have simple in structurely, easy to maintenance, processing cost is low, the manufacturing efficiency advantages of higher.Go for fire-fighting monitor producer.

Embodiment
Like Fig. 1, shown in 2 and 3, the present invention is a kind of many device for revolving and driving of valve control usefulness.
The structure of present embodiment: a kind of many device for revolving and driving of valve control usefulness; Comprise motor 11, main box body 6, reducing gear, range controlling mechanism and long cable section of ingoing line sealing mechanism, reducing gear comprise the worm shaft 9 that in bearing support 13, is connected with motor shaft 12 through key, with the worm gear 2 and the live axle that passes worm gear 2 and be connected 1 of worm shaft 9 Vertical Meshing; Range controlling mechanism comprises the stroke cover 3 that is connected with live axle 1 one ends, be through the stroke levers combination 4 of installing in the stroke cover 3, make up counter that 4 one ends are connected with the stroke lever that stretches out the stroke lever cover casing outside makes up 5 and make up 5 explosion-proof travel switch 8 that install with counter; The long cable section of ingoing line sealing mechanism is made up of the inlet wire cover 17 that baffle plate 15, sealing plug 19, packing ring 16 and gland nut 18 are housed in it successively; Main box body 6 is fixedly connected with bearing support 13, is fixed with control box cover 7 to form the explosion-proof chamber of drive unit through concavo-convex seam on the main box body 6; Worm shaft 9 the other ends expose to main box body 6 sides, only are useful on interior six sides of the moving handle 14 of connection hand on its end.The input power of motor 11 is through reducing gear and have stroke shaft to spread out of, and the output torque can reach 70r/min.Explosion-proof travel switch 8 mainly is used for controlling the end position of fire-fighting monitor.
The working procedure of present embodiment: after energized, motor 11 work, motor shaft 12 is through key and 9 coaxial connections of worm shaft; Thereby drive worm shaft 9 rotations; Worm shaft 9 drives worm gear 2 rotations, and worm gear 2 passes to power on the live axle 1, realizes the power output that motor 11 drives then.Live axle 1 rotation drives stroke cover 3 and stroke overlaps stroke lever combination 4 rotations of 3 the insides, and then drives counter combination 5, comes the stroke of controlling and driving axle 1 through the adjustment of the explosion-proof travel switch 8 in the counter combination 5.Take off control box cover 7; And take off inlet wire and overlap baffle plate 15, sealing plug 19, packing ring 16 and gland nut 18 in 17; Inlet wire cover 17 is installed on the main box body 6; Import cable into gland nut 18, sealing plug 19 successively again, then import cable into control box cover 7 through inlet wire cover 17, then can wiring debugging running.This moment, baffle plate 15 was inoperative, and it only seals when product export.
When the needs manually-operable, manual handle 14 is inserted worm shaft 9 the other ends expose among interior six sides, rotation manual handle 14 can drive worm gear 2, live axle 1 via worm shaft 9, realizes manually-operable.
More than one embodiment of the present of invention are specified, but said content is merely preferred embodiment of the present invention, can not be considered to be used to limit practical range of the present invention.All equalizations of doing according to application range of the present invention change and improve etc., all should still belong within the patent covering scope of the present invention.
