Electric Knife Gate Valve is generally selected by water supply and drainage professional technical personnel in the engineering design of the valve electric device to put forward specific functional requirements, and professional manufacturers of electric device selection. However, in the actual project often occurs in the field installation, valve electric drive device and control system conflict and other mismatches. This is usually due to the determination of the functional requirements of the electric device when there is unreasonable or incomplete.
Knife Gate Electric Device Composition:
The electric device is generally composed of the following parts: Special motor speed reducer to reduce the output speed of the motor; stroke control mechanism to regulate and accurately control the opening and closing position of the valve; torque limiting mechanism, to adjust the torque (or thrust) and not to exceed a predetermined value; manual, electric switching mechanism, manual or electric operation of the interlocking mechanism; open degree indicator to show the valve in the open and close process. Among them, the stroke control mechanism, torque limit mechanism, manual, electric switch mechanism and opening degree indicator are collectively referred to as electric actuators.
Points To Note When Selecting And Determining Functional Requirements For Electric Installations:
When selecting the type of electric device and determining the function requirement, the key points need to be noticed include determining the IP protection grade, the power supply voltage, the 90 running time of the electric device and the form of the electric actuator.
