Maintenance Of Idle Valves
Maintenance of idle valves should be carried out together with equipment and pipelines, and the following tasks should be done:
Clean the valve
The inner cavity of the valve should be purged and cleaned without any residue or water solution. The outside of the valve should be wiped clean without any dirt, oil,
Two, complete valve parts
After the valve is missing parts, it cannot be disassembled to make up for the west. The valve parts should be equipped to create good conditions for the next use and ensure that the valve is in complete condition.
Three, anti-corrosion treatment
Take out the packing in the stuffing box to prevent electrochemical corrosion of the valve stem. The valve sealing surface, valve stem, valve stem nut, machined surface and other parts shall be coated with anti-rust agent and grease according to the specific situation; the painted parts should be painted with anti-corrosion Rust paint.
Four, protection and protection
Prevent the impact of other objects, manual manipulation and disassembly, when necessary, the movable parts of the valve should be fixed, and the valve should be packaged and protected.
Five, regular maintenance
Valves that have been idle for a long time should be inspected and maintained regularly to prevent rust and damage to the valve. For valves that have been idle for too long, they should be tested together with equipment, devices, and pipelines before they can be used.
