May 05, 2024| What are the advantages of valves with electric actuators?
Valve electric device refers to a driving device controlled by electricity (motor, electromagnet, etc.). Valves driven by electric devices have the following advantages: ① It can greatly reduce the time to open and close the valve; ② It can greatly reduce physical consumption; ③ The valve can be installed in any high-level situation that cannot be operated manually, is difficult to access or is far away; ④ It is conducive to the automated operation of the entire device and can reduce operating personnel; ⑤ Generally, it is equipped with an overload protection device to ensure that the valve of normal operation.
The electric device operated by the valve motor adopts an electric motor-driven device, which generally includes the following components: electric motor, reducer, mechanical super-torque device, travel switch and some necessary electrical components. It can achieve the following actions: press the button, open or close Valve; ② When reaching the limit position of opening and closing, due to the action of the travel switch, the power supply can be automatically cut off to stop the motor; ③ When the driving torque exceeds the specified limit, the power supply can be automatically cut off due to the action of the mechanical over-torque device, causing the motor to stop rotating. Stop rotating; ④ When the motor fails or the power supply is interrupted, it can be converted to handwheel manual operation; ⑤ Interlocked with other mechanisms and electrical driving devices such as units, when the relevant components of the automatic system (relays, photoelectric tubes, end switches and other ), the motor can automatically stop, rotate forward or reverse.
