Integrated intelligent valve electric device

Abstract

The invention discloses an integrated intelligent valve electric device. The integrated intelligent valve electric device comprises a two large parts including a transmission end and a circuit systemend; and the integrated intelligent valve electric device is characterized in that the transmission end comprises a motor, a first transmission gear, a second transmission gear, a third transmission gear, a worm gear, a worm, a stroke controller, a middle gear, an adjustable opening position indicator, a torque controller, a disc spring assembly, an input shaft and an output shaft. The motor and the first transmission gear are coaxially rotated; the first transmission gear is in gear meshed with the second transmission gear I; the second transmission gear and the input shaft are coaxially rotated; the input shaft and the worm are coaxially rotated; a gear positioned above the worm is meshed with the worm gear; the output shaft is vertically embedded in the center of the worm gear; the input shaft is also connected with the torque controller, the disc spring assembly and the third transmission gear; and the worm gear is coaxially connected with the stroke controller, the middle gear andthe adjustable opening position indicator. The integrated intelligent valve electric device disclosed by the invention has the characteristics of being accurate in control and high in anti-interference property.

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
