How should the valve be maintained in peacetime in order to better serve people?
1. Valve storage environment needs to be noted, should be stored in a dry and ventilated room, and blocked at both ends of the path.
2. Valves installed and in use should be regularly repaired to ensure their normal operation.
3. Should check whether the valve sealing surface is worn out, and repair or replace according to the situation.
4. Check the wear of trapezoidal threads on the stem and stem nuts, and whether the fillers are out of date, and make necessary replacements.
5. The sealing performance of the valve should be tested to ensure its performance.
6. Valves in operation should be intact, bolts on flanges and brackets are complete, threads are not damaged, and there is no loosening.
7. If the valve is used in a harsh environment and susceptible to rain, snow, dust, sand and other contaminants, it should be installed for the valve stem protective cover.
