How to properly install, maintain and operate the valve
One, installation 1. Direction and location 2. Construction work. Be careful when installing to avoid the effects of valves that are made of brittle materials.
3. Protective facilities 4. Bypass and meter 5. Filler replacement
Second, maintenance (1) inspection and maintenance. The purpose is to keep the valve safe from damage and reduce the quality.
(2) Maintenance. The purpose is to extend the life of the valve to ensure reliable opening and closing.
Third, operation 1. Open and close the valve. Use force to open and close smoothly, valve, not shocking. Clean the sealing surface regularly.
2. Note.
(1) Above the high temperature valve of 200 degrees Celsius, after the normal use temperature increases, the gap increases when the belt is heated. Therefore, we must tighten the bolts again, otherwise leakage may occur.
(2) In the cold climate, water valves, such as long-term closure, should be water drain valves.
(3) No metal valve, some hard and brittle, low strength, can not be too large in opening and closing operation, especially can not make. The valve should be careful not to bump.
(4) When using the valve, the packing should not be too tight so as not to leak, so as to avoid too much pressure of the valve stem, quickening the wear and opening and closing work.
