Electric control pneumatic valve common operation skills

Electric adjustment pneumatic valve is a common adjustment pneumatic valve model, by the electric actuator with regulating pneumatic valve body of two parts. With electric operation instead of manual operation, make higher controlling accuracy, and save the human, also can realize the remote control. Has two kinds of straight stroke and stroke, straight travel electric regulating pneumatic valve is driven by electric actuator pneumatic valve do rectilinear motion from top to bottom, angular travel electric regulating pneumatic valve driven by electric actuators in regulating pneumatic valve is 0 Rotate 90 °. Electric adjustment are heavily dependent on electric pneumatic valve actuator drive the adjustment of pneumatic valve opening and closing, line of electric actuators are acceptable from current or voltage analog signal control system, by controlling the different opening of pneumatic valve to achieve the purpose of adjusting parameters such as flow, pressure pipeline medium, realize remote automatic control. According to different medium, the pneumatic valve body material also accordingly have different choices, common carbon steel, the choice of corrosive materials such as stainless steel 304 or 316, 316 l, also can choose lining fluorine pneumatic valve adjustment.
electric regulating pneumatic valve operating skills:
1. Electric adjustment pneumatic valve electric device starts up, should be in accordance with the electrical plate on the start button, the motor immediately start, to a certain time after pneumatic valve opens, motor automatically shut down, on the electrical panel had 'open' signal lights; If electric regulating pneumatic valve closing, should press the close button on the electrical panel, pneumatic valve close direction function, fitted to the pneumatic valve, 'closed' signal 'light. Pneumatic valve operation, is opened, is closed, somewhere in the middle of light should be the corresponding instructions. Pneumatic valve indicator signal accords with the practical action, and can be locked tightly, nail, electric apparatus is normal. If pneumatic valve, open and close operation, the light is not bright, sold in the accident, the light, transmission device is not normal, should check the reason, repair, debugging. Electric actuator has a fault, closed lax, to deal with, when action should be the dial to the manual position, turn the handwheel clockwise close the pneumatic valve, pneumatic valve counterclockwise to open. Electric actuator cannot reverse button in the running, if need to correct, due to misoperation should first press the stop button, and then start again.
