The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention;
fig. 2 is a side view of the present invention;
fig. 3 is a cross-sectional view of the actuator.
Detailed Description
Referring to fig. 1 to 3, the present invention discloses a pneumatic butterfly valve, which comprises a valve body 1, a valve plate 2 rotatably connected to the valve body 1, and a driver fixedly connected to the valve body 1, the driver comprises a shell 4 and a cylinder body 3 fixed with the shell 4, a driving shaft 5 arranged in the shell 4 through a bearing 6 is arranged in the shell 4, the bearing 6 is a self-lubricating bearing 6, the driving shaft 5 is provided with a gear 7, the gear 7 is a straight gear 7, a piston rod 8 and a piston are arranged in the cylinder body 3, the piston rod 8 is provided with a plurality of driving teeth 9, and a section of the piston rod 8 with the driving teeth 9 is positioned in the shell 4 and is meshed with the gear 7, the driving shaft 5 is connected with the shaft end of the valve plate 2, the end of the driving shaft 5 is provided with a hole, the hole wall is provided with a key groove, and the shaft end of the valve plate 2 is provided with a key matched with the key groove, so that the connection and transmission are facilitated.
The working principle of the structure is briefly described, when the valve plate 2 needs to be rotated, air is introduced into the cylinder body 3, the piston drives the piston rod 8 to move, the driving teeth 9 on the piston rod 8 drive the gear 7 to rotate, the gear 7 drives the driving shaft 5 to rotate, the driving shaft 5 drives the valve plate 2 to rotate, and therefore the valve is opened, and otherwise, the valve is closed.
As shown in the figure, an adjusting screw 10 in threaded connection with the housing 4 is further arranged in the housing 4, a limiting nut 11 is arranged on the adjusting screw 10, and the adjusting screw 10 can be in contact with the piston rod 8 and limit the movement of the piston rod 8, because the cylinder cannot accurately position the stroke of the piston rod 8, and only has the maximum stroke and the minimum stroke, we set the adjusting screw 10 to control the stroke of the piston rod 8, the stroke of the piston rod 8 is controlled by the length of the adjusting screw 10 in the housing 4, and the end of the adjusting screw 10 can be clamped with the end of the piston rod 8, so we can control the opening angle of the valve plate 2.
As shown in the figure, a signal switch 12 is further arranged in the housing 4, and a plectrum 13 for triggering the signal switch 12 is arranged on the driving shaft 5, so that a controller can be informed when the valve plate 2 is opened to a predetermined angle, and the signal switch 12 can be a proximity switch.
As shown in the figure, casing 4 includes half upper shell 14, half lower shell 15 and drain pan 16, gear 7 is arranged in half upper shell 14, just signal switch 12 and plectrum 13 are arranged in half lower shell 15, be equipped with the upper shaft hole in half upper shell 14, be equipped with lower shaft hole in half lower shell 15, gear 7 passes through bearing 6 and upper shaft hole card, and is equipped with the step on the drive shaft 5, and this step passes through bearing 6 and lower shaft hole looks card, half upper shell 14 passes through screw connection with half lower shell 15, and half lower shell 15 passes through screw connection with drain pan 16, through the aforesaid structure of separating we can be convenient for manufacturing and installation driver relevant part.
The pneumatic butterfly valve provided by the embodiment of the present invention is described in detail above, and the principle and the implementation of the present invention are explained by applying specific examples herein, and the description of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
