Working principle of the electric proportional control pneumatic valve _ electric proportional control pneumatic valve applications

electric proportional control pneumatic valve working principle is what? Application field of electric proportional control pneumatic valve what? We all know that the electric proportional control pneumatic valve in control form is controlled by pneumatic valve opening Angle size to achieve the opening and the cross section area.
the control process of electric proportional control pneumatic valve is in the process of motor rotation, continuously in a linear feedback resistance to the control unit, control unit according to the measured values and electric pneumatic valve, compare and judge the feedback resistance and signal control to arrive at the target location stop action immediately. Then, fluid network in Asia to bring you the working principle of electric proportional control pneumatic valve and application field are introduced.
a,
electric proportional control pneumatic valve working principle of electric proportional control pneumatic valve working principle of the control principle of
electric proportional control pneumatic valve electric actuator and execution unit constitute a pneumatic valve body assembly. The electric actuator power supply for: usually used ACV or listed ACV, listed the most commonly used control signal is ~ mA, also have - at the same time V weaknesses such as signal system. Built-in electric actuator servo controller, the controller will current signal, Or the Angle of the voltage signal is converted to motor trip signal, driven by the motor output gear and worm drive the worm gear deceleration, do - to drive the pneumatic valve stem ° part of the rotary motion, angular travel control functions.

electric proportional control pneumatic valve working state feedback electric parts: motor drive gear is passed to the electrical control part of the operation of auxiliary shaft gear drive SanJieTou sliding potentiometer resistance value of the variable positioning signal output pneumatic valve, power line is composed of three wires and two sets of limit switch assembly ( Open, close, the public line
2, electric proportional control pneumatic valve applications
electric proportional control pneumatic valve is suitable for various industrial automation process control computer control system ( DCS system and measuring instrument of flow, temperature, pressure regulation of the process parameters such as automatic control equipment. Mainly used in: industrial automation process control field. For example: petrochemical refinery, pipeline oil transportation; Power plant steam turbine cooling and lubricating oil supply, combustion air regulation; In the environmental protection sewage treatment fluid delivery cut off, switch, flow control and so on all kinds of industrial automatic process control.
