The through hole shape that described chute is elongated, described slide-bar is installed in chute and the top of slide-bar is connected with axle cap.
On described driving cylinder, be fixed with cylinder scaffold, on cylinder scaffold, offer mounting hole.
On the front-end face of described driving cylinder piston rod, offer interior threaded hole, on described guide pad, be connected with and coordinate the screw column of installing with above-mentioned interior threaded hole.
The signal output part that the rear end of described driving cylinder is provided with cylinder location sensor and this sensor is connected on described controller.
Adopt said structure, slide-bar promotes leading arm and rotates, thereby band ovable valve stem connecting head rotates, realize the opening and closing of ball valve, utilize controller and solenoid valve to driving the flexible state of cylinder automatically to control, overall structure is simple, reliable transmission and control are convenient, have realized automation; Drive cylinder can be fixed on each position of machine by cylinder scaffold, easy accessibility; Cylinder location sensor is set, can monitors in real time the position of cylinder piston rod, controller can carry out accurate flow control according to the unlatching size of ball valve.
In sum, the utlity model has simple in structure, stable performance and control advantage easily.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is along the sectional view of A-A direction in Fig. 1.
Embodiment
With reference to accompanying drawing, ball valve driving mechanism of the present utility model comprises the valve body 2 that drives cylinder 1 and top to be provided with valve rod connecting head 21, on the valve rod connecting head 21 of valve body 2, be provided with on leading arm 3 and this leading arm 3 and offer long strip chute 4, drive the front end of cylinder piston rod 11 that guide pad 5 is installed, on guide pad 5, be connected with driving the vertically disposed slide-bar 6 of cylinder piston rod 11 and this slide-bar 6 and be slidably mounted in above-mentioned chute 4.In said structure, guide pad 5 is followed and is driven cylinder piston rod 11 to move forward and backward, and drives slide-bar 6 to move forward and backward, and moving forward and backward of slide-bar 6 drives leading arm 3 to rotate, and the rotation of leading arm 3 can complete the opening and closing action of valve body 2.Wherein, for chute 4, as shown in the figure, and the through hole shape that chute 4 is elongated, slide-bar 6 is installed in chute 4 and the top of slide-bar 6 is connected with axle cap 61.The effect that axle cap 61 is set is to avoid leading arm 3 landing from slide-bar 6, and the external diameter of axle cap 61 is greater than the width of chute 4.
For the control that drives cylinder 1, in the utility model, drive the control end that is connected with solenoid valve 7 and this solenoid valve 7 in the gas circuit of cylinder 1 to be connected on a controller 8.Break-make by 8 pairs of solenoid valves 7 of controller is controlled, thereby to driving cylinder piston rod 11 position automatically to control.Because transmission of the present utility model is very stable and reliable, therefore the utility model can be very easily for controlling the synchronous unlatching of two ball valves or closing, the utility model that is shown in Fig. 1 is applied in two schematic diagram on valve body 2, two valve bodies 2 are arranged side by side, and drive cylinder 1 to be all symmetrical arranged two covers with the transmission part being connected thereon.For solenoid valve 7, can each drive cylinder 1 correspondence to arrange one also can two to drive cylinders 1 to share one, shown in figure is the former.Controller 8 can be controlled two and drive cylinder 1 synchronization motion, and certainly, for shown in Fig. 1, each drives in the situation of a cylinder 1 corresponding solenoid valve 7, controller 8 also can be controlled respectively two course of action that drive cylinder 1 according to actual conditions.
