Pneumatic control valve also named pneumatic regulating valve. A valve that regulates the flow of a fluid. The actuator is operated by compressed air.If the pneumatic control valve fails during use, it will cause great harm to the normal and stable operation of the system. Therefore, the pneumatic control valve should be maintained regularly.
1. Passive Maintenance
When the pneumatic control valve fails, the regulating valve should be overhauled to find out the cause of the fault and timely repair.
2. Preventive Maintenance
Regularly clean the control valve, keep the hygienic valve and the complete and durable parts, regularly flush the pipeline, pay attention to the blockage and garbage in the pipeline, and regularly check the fixed joints of the control valve to ensure the components. The corrosion resistance is good for lubrication.
When installing the pneumatic regulating valve, it reduces the hard-bending hard bending phenomenon during installation, reducing the pressure and reducing the deformation. Keep the distance between the regulator valve and the compressor to reduce vibration from the vibration source. Regular inspection of the control valve should pay close attention to the operation of the control valve, check whether the packing leaks and regularly add lubricating oil to the packing.
3. Predictive maintenance
The operation information of the control valve is obtained through a smart meter or other diagnostic devices, and the regulating quality and diagnostic function of the control valve are enhanced. Through the diagnosis of smart meters or other diagnostic equipment, problems in the control valve can be discovered in time, and solutions can be found in time for maintenance. Increase the development and use of intelligent valve positioners.
