Problems solved by technology

[0004] During the use of the control valve, there is always friction between the valve stem and the packing. If the valve stem moves too many times, it will cause damage to the valve stem and the packing, resulting in leakage of the control valve. At this time, it is necessary to stop production for maintenance. It will bring great economic losses to users
The traditional valve positioner has no valve position accumulation function, so it is impossible to predict the maintenance time of the control valve in advance

Abstract

The invention discloses a valve position accumulation method of an intelligent valve positioner. The method comprises: collecting valve position data according to a set sampling frequency; The amount of change in the position data is accumulated to obtain the cumulative value of the valve position; the cumulative value of the valve position is compared with the set value of the valve position; and an alarm prompt is output according to the comparison result. The present invention can accumulate valve position data, can predict in advance that the regulating valve needs to be maintained, and can issue a warning to the user, so that the user can maintain the regulating valve in a planned way in advance.

Description

technical field [0001] The invention relates to the field of valves, in particular to a valve position accumulation method, device, storage medium and electronic terminal of an intelligent valve positioner. Background technique [0002] Intelligent valve positioner is widely used in field control instruments in petrochemical and other fields. It is the main accessory of control valves. It is usually used in conjunction with pneumatic control valves. Its main function is to receive control commands from central control and precisely control the valve opening. [0003] The control of valve opening by intelligent valve positioner 1 is a closed-loop control, such as figure 1 As shown, it is mainly composed of several parts such as a sensor, a main board, and an I / P unit. The function of the sensor is to measure the position of the valve stem 3 in real time, and send the measured data to the main board for collection; the function of the main board is mainly to collect through th...
