Abstract

The invention relates to a valve electric device which comprises a box body, wherein one end of the box body is provided with a transmission device moving back and forth; the other end of the box body is provided with a torque sensor; the transmission device is acted to a bearing base through a bearing; the middle part of the bearing base is connected to a sleeve; the sleeve is connected to the torque sensor by virtue of a connecting plate; and a disc spring is arranged on the bearing base in a sleeving mode. The disc spring can bear relatively great load within a relatively small space; and the valve electric device is relatively free to combine, and is wide in scope of application.

Description

technical field [0001] The invention specifically relates to a valve electric device, which belongs to the field of mechanical manufacturing. Background technique [0002] In the intelligent valve electric device, the push-pull torque sensor is installed on the other end of the worm part. When the valve is opened or closed, the motor of the valve electric device drives the worm to move left or right. It is transmitted to the push-pull torque sensor, and the corresponding signal is transmitted to the central processing unit of the valve electric device to implement the required control. However, when the output speed of the valve electric device is very high, the speed of the worm is higher, and the impact force is very large, the push-pull torque sensor undergoes plastic deformation, and the measured torque data is distorted. Contents of the invention [0003] The purpose of the present invention is to provide a valve electric device, by adding a disc spring to the transm...
