Abstract

The invention discloses a valve electric device for manual safety power-off. The worm is movably connected to the lower surface of the worm wheel. There is a cavity inside the worm wheel. The temperature protection switch is electrically connected to the inner cavity of the worm wheel. The temperature protection switch is composed of an insulating shell, a ceramic rod, and a bimetallic sheet. , the present invention can use the bimetal sheet as a temperature-sensing component in the process of electric control to perform automatic induction operation when the motor is overheated, and cut off the power supply of the motor in time to protect the motor, avoiding the failure or even damage of the motor, and effectively improving the performance of the equipment. safety performance.

Description

technical field [0001] The invention relates to a valve electric device for manual safety power-off, which belongs to the technical field of valve electric control. Background technique [0002] Due to the increasing automation of production processes such as power stations, petroleum, and chemical industries, control technologies such as remote control, centralized control, program control, and automatic control have been widely used. , Easy adjustment, small size, light weight valve electric device to meet the needs of various performance valves. 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, wh...
