AI Technical Summary
Technical Problem
The existing positioning methods of electric valves have problems such as damage and incomplete closing due to motor inertia, which are particularly noticeable when there is wear or changes in medium pressure.
Method used
The valve opening and closing is controlled by detecting changes in motor current using an E-shaped electromagnet and an armature torque limiting device. The torque limiting is adjusted by magnetic attraction to avoid rigid contact. The controller adjusts the electromagnet voltage to achieve precise limiting.
Benefits of technology
It effectively prevents valve damage due to excessive rotation, ensures reliable valve closure, adapts to wear and changes in medium pressure, simplifies the commissioning process, and can be completed by ordinary operators.

Abstract
一种电动阀门的控制方法，用来控制阀门的启闭，其通过一控制器控制电动机和转矩限制装置，转矩限制装置由E形电磁铁和条形衔铁构成，通过调节E形电磁铁上的电压，能改变磁吸力，即能方便地调节转矩限制值，以满足阀门关闭或开启所需的转矩；根据电机电流的拐点来对阀门限位，在阀门关闭时，可消除阀板或阀座磨损带来的影响，也可消除阀门内介质压力和温度变化带来的影响，使阀门可靠关闭。
