The installation of electric control pneumatic valve

。 Electric control pneumatic valve is better position installed in a horizontal pipe, any special needs can also be installed, in addition to the electric regulating the use of pneumatic valve upside down. Greater impact pneumatic valve add dumping or weight should be installed in the rack.
。 Calibration should be installed to make the flow direction of medium pneumatic direction of the arrow on the valve body. General electric control pneumatic valve should be set the by-pass pipe. Pneumatic valve diameter is not in conformity with the tube diameter, taper pipe should be used. Electric control pneumatic valve installation location should leave enough space, convenient debugging and maintenance.
。 Electric regulating pneumatic valve should be installed in the pneumatic valve, in order to avoid additional pressure, when the control place long, pneumatic valve is installed in the pipe bracket shall be installed, the use of vibration, shock absorber should take appropriate measures.
。 Electric control pneumatic valve before installation should clean pipe, remove dirt, completely open the pneumatic valve is installed in the pipeline, pneumatic valve, cleaning and tightness test connection.
。 Notice moistureproof, dustproof, speeds up the dry place of wear and soy sauce, leakage caused by packing, in the open BBS equipment installation shield should also be added, to prevent exposure to moisture.
。 Open the external connector housing. Before starting work pneumatic valves, actuators and actuator housing and remove money should cut off the main power supply.
。 In the electrical wiring is properly check the optical switch, artificial major travel agencies have no, for the first time send electrical signals after shell short putt and stem were observed, in two direction installation errors, if the actuator for single-phase motor only opening and closing of the connection communication, pneumatic valve stroke help no more than more.
。 Phase V power line for the 'L' on both sides of the centerline of the connected to: 'N' side. 。 In order to avoid the actuator into the condensate in the case of environmental temperature or humidity change, you need to install thermal resistance. 。 Handwheel: you must first disconnect the power supply, and then artificial hand wheel. 。 In electric regulating pneumatic valve installation, do not use welding operation, directly inside line on the low side with bad people.
