The maintenance of gate valve is very important to ensure its normal operation and working performance. The following are some suggestions for gate valve maintenance:
Regular inspection: check the gate valve regularly, including sealing surface, packing, valve stem, fluid channel, etc. Check for leakage, wear, corrosion, etc. and debris blockage.
Keep clean: regularly clean the debris and dirt inside the gate valve to ensure smooth fluid passage. At the same time, keep the external surface clean to prevent rust and dirt accumulation.
Lubrication: regularly lubricate the rotating parts of the gate valve to prevent abrasion and jamming. Select the appropriate lubricant according to the actual situation and operate according to the operating instructions.
Fastening: regularly check and tighten the bolts and nuts of the gate valve to ensure that they are firmly fixed and prevent looseness and falling off.
Replacement of sealing ring and packing: regularly replace the sealing ring and packing according to the actual situation. The performance of the sealing ring and packing will be reduced with the change of service time and environmental conditions, so they need to be replaced in time to ensure the performance.
Adjustment: if the sealing performance of the gate valve is reduced or the operation is not flexible, appropriate adjustment can be made. For example, adjust the compression amount of the seal ring, and adjust the fitting degree of the valve stem to restore its normal performance.
Repair and replacement of parts: repair or replacement shall be carried out in time in case of damage or performance degradation of gate valve parts. For example, replace worn seals, repair damaged stems, etc.
Record and tracking: establish the maintenance record of gate valve, record the time, content, operator and other information of each inspection, lubrication and replacement of parts. This will help track the status and maintenance history of the gate valves, identify potential problems in a timely manner and take appropriate actions.
To sum up, regular inspection, cleaning, lubrication, fastening, replacement of sealing ring and packing, adjustment, repair and replacement of parts and other measures are required for the maintenance of gate valve. At the same time, the establishment of a record and tracking system is conducive to timely identifying potential problems and taking corresponding measures. Reasonable maintenance can extend the service life of gate valve, improve its reliability and reduce the risk of failure.
