Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
The percentage and angle indicating device for the valve limit switch comprises an indicating cover, a valve opening indicating disc 1, a magnetic attraction fixing device 2, a valve angle indicating disc 3, an indicating needle rotating shaft 4 and an indicating needle 5.
An indicating needle rotating shaft 4 is arranged at the center of the indicating cover, and one end of an indicating needle 5 can rotate around the indicating needle rotating shaft 4360 degrees. The indicating needle 5 is provided with two indicating arrows which are respectively used for indicating scales on the valve opening indicating dial 1 and the valve angle indicating dial 3 and can indicate the percentage and the angle of the valve opening and closing at the same time.
And engraving a valve opening indicating disc 1 and a valve angle indicating disc 3 at a second quadrant of the indicating cover, wherein the valve opening indicating disc 1 is positioned on the outer side of the valve angle indicating disc 3.
