Abstract
The utility model relates to a drive device for opening a ball valve and closing a valve, which is composed of a shell body, a shell cover, a direction cover, a small shell body, a small shell cover, a shaft gear, a big gear, a worm rod shaft, a worm wheel and a hand wheel. A secondary drive is carried out through the engagement and the connection of the shaft gear and the big gear, and the worm rod shaft and the worm wheel are driven to drive the ball valve to be closed or to close the valve. The utility model is more labor-saving than single-stage drive and is particularly suitable for matching with a large ball valve.
Description
The utility model relates to the transmission device that ball valve opens and closes valve.
General ball valve open and close valve all is that labor intensity is big with manually-operated, renders a service not highly, and closing velocity is slow, even the accident that some jeopardize safety in production can take place, and is when the opening and closing of the large-scale ball valve of manual operations, just difficult more.The existing hoist of adapted on ball valve generally all is the one-level gear transmission, and it is big that its shortcoming remains operation labor intensity.
The purpose of this utility model is exactly the hoist that exploitation provides a kind of rapid operation.
The technological scheme that realizes this purpose is to adopt the secondary gear transmission, and it includes housing, cap, point to lid, small shell, small shell lid, shaftgear, gearwheel, worm shaft, worm gear and handwheel, its technical characterstic is that shaftgear and gearwheel are connected with a joggle, gearwheel connects worm shaft, and worm shaft and worm gear engagement connect, and are closed or Open valve by the worm gear drives ball valve.The transmission handwheel by the secondary transmission of shaftgear and gearwheel, drives worm shaft and drives the worm gear rotation.
The utility model adopts the structure of shaftgear and the transmission of gearwheel secondary, than existing hoist, has and operates more labour-saving advantage, longer operating life.Especially be fit to the supporting use of big ball valve.
Below, in conjunction with accompanying drawing of the present utility model, embodiment is further described.
Fig. 1 is the utility model topology view.
Fig. 2 is that the A of Fig. 1 is to topology view.
Shaftgear 9 connects with gearwheel 8 engagements, the other end connects handwheel 10, drive gearwheel 8 by handwheel 10, shaftgear 9 and gearwheel 8 be assemblied in the inner chambers that small shell 7 and small shell lid 11 forms and with small shell 7 and little cap 11 movingly, the center hole of gearwheel 8 connects with worm shaft 6 keyways, as shown in Figure 2, worm shaft 6 two ends and housing 1 and small shell 7 are movingly, worm shaft 6 connects with 4 engagements of the worm gear in housing 1 and the cap 5, worm gear 4 mesopores are respectively with housing 1, the center hole of cap 5 movingly, the mesopore of worm gear 4 connects with external ball valve axle by keyway, drives ball valve and opens or throttle down.Cap 5 is marked with the mark of "on" and "off", points to cover to have arrow on 3 and indicate, and " opens " or the position of " pass " with worm gear 4 sense of rotations.Worm gear 4 rotates with worm shaft 6 engagements, and the rotation angle of worm gear is finely tuned the angular dimension that spacing double-screw bolt 2 can change worm gear 4 rotations, the peak rate of flow of regulating valve and minimum discharge at 0-90 °.
