An integrated intelligent valve electric device

Abstract

The invention discloses an integrated intelligent valve electric device, which includes two parts: a transmission end and a circuit system end. Stroke controller, intermediate gear, adjustable opening indicator, torque controller, disc spring assembly, input shaft and output shaft, the motor and the transmission gear rotate coaxially, the first transmission gear and the second transmission gear meshing, the transmission gear 2 rotates coaxially with the input shaft, the input shaft rotates coaxially with the worm, the gear above the worm meshes with the worm wheel, the center of the worm wheel is vertically embedded with an output shaft, and the input shaft is also connected with a rotating Torque controller, disc spring assembly and transmission gear 3. The worm gear is coaxially connected with a stroke controller, an intermediate gear and an adjustable opening indicator. The present invention has the characteristics of precise control and strong anti-interference.

Description

technical field [0001] The invention relates to the technical field of intelligent control devices for industrial general valves, in particular to an integrated intelligent valve electric device. Background technique [0002] The valve electric device is the main mechanism for driving and controlling the valve, and it has been widely used in various industrial sectors of our country since the 1950s. Our country needs about tens of thousands of valves every year. At present, the products designed in the 1960s and 1970s are still mass-produced and used, and their main function is to replace manpower to operate those large-caliber valves. [0003] With the improvement of modern industry's requirements for valve electric devices, the shortcomings of existing valve electric devices, especially their control systems, are exposed more and more obviously in terms of function and use. For example, the control error is large and difficult to overcome, there is no reliable fault handl...

AI Technical Summary

Problems solved by technology

For example, the control error is large and difficult to overcome, there is no reliable fault handling and timely alarm mechanism, the man-machine interface is not good, it is difficult to calibrate and maintain on site, and the working conditions of the valve electric device are often in bad conditions. In order to ensure long-term normal work, There are high requirements on the anti-interference performance and reliability of the system
