The working performance of the intelligent valve electric actuator will directly affect the working quality of the entire regulating system. Because the intelligent valve electric actuator is in direct contact with the regulated medium at the scene, the working environment is very harsh, so it is easy to produce various failures. In the production process, in addition to eliminating these faults at any time, regular maintenance and regular inspections must also be carried out. Especially for the control valve with particularly bad operating environment, more attention should be paid to maintenance and regular maintenance.
Daily maintenance of pneumatic control valve:
When the control valve uses graphite-asbestos as filler, lubricating oil should be added to the filler once every three months to ensure that the control valve is flexible and easy to use. If the packing pressure cap is found to be very low, the packing should be supplemented. If the PTFE packing is found to be hardened, it should be replaced in time; the operation of the regulating valve should be paid attention to during the tour inspection, and the valve position indicator and regulator output should be checked. Does it fit.
