Electric valves are generally selected by the water supply and drainage professional. The water supply and drainage professional and technical personnel must put forward specific functional requirements for the electric device of the valve during the engineering design, and the professional manufacturer shall select the electric device. However, in actual engineering, there is often a mismatch between the valve electric drive device and the control system during on-site installation. This is usually due to unreasonable or imperfect aspects in determining the functional requirements of electric devices.
Look at the composition of the valve electric device
The electric device generally consists of the following parts: a dedicated motor deceleration mechanism to reduce the output speed of the motor; a stroke control mechanism to adjust and accurately control the opening and closing position of the valve; a torque limit mechanism to adjust the torque (or thrust) ) And make it not exceed the predetermined value; manual and electric switching mechanism, interlocking mechanism for manual or electric operation; opening indicator, used to show the position of the valve in the opening and closing process. Among them, the stroke control mechanism, torque limit mechanism, manual, electric switching mechanism, and opening indicator are collectively referred to as electric actuators.
