The regulating valve is a non-negligible part of the automatic control and should be inspected and maintained regularly. Maintenance is performed when the equipment has not failed. From the analysis of the currently used regulating valve data, the state of the regulating valve is foreseen, and the maximum limit of the regulating valve is utilized, which can greatly reduce the probability of failure.
The regular maintenance of the regulating valve is as follows:
1. Regularly check the connection status of each connection point, corrosion, and replace the connection if necessary.
2. Regularly adjust the packing box and other sealing parts of the regulating valve. If necessary, replace the sealing parts to maintain the sealing of the static sealing point.
3. Regularly clean the outside of the regulating valve.
4. Regularly discharge and clean the gas source or hydraulic filtration system.
5. Add lubricant to the parts to be lubricated regularly.
