Method for extending the service life of stainless steel hard seal butterfly valves
Let's take a look at the specific maintenance methods that can effectively avoid the corrosion of stainless steel hard-seal butterfly valves and extend the service life:
1.In the process of using stainless steel hard sealing butterfly valve, we should always clean the valve body and maintain and lubricate the transmission. We need to troubleshoot frequently to detect faults and clear them in time.
2. Fill the packing evenly and tighten the cover to prevent the media from leaking from the packing. This phenomenon can lead to rust after a long time.
3. Pay attention to the connection mode and direction of the valve to prevent leakage and erosion caused by misalignment.
4. Stainless steel hard seal butterfly valves are only used for adjustment. It will not be used for full opening or full closing. The reason is that the structural characteristics of the butterfly valve are not suitable for truncation. If it is cut off, it will cause the sealing surface to accelerate wear.
5. Valves that have been left unused for a long time need to be regularly checked and cleaned in time. Both ends of the butterfly valve passage should be closed to prevent long-term air oxidation. Keep the product in a dry and ventilated place and do not stack it or store it in the open air.
6. Eliminate the dirt of the valve parts before installation and carefully check the pressure of the valve mark to check whether the diameter meets the requirements of use, thus eliminating the defects caused by the transportation process.
7. Use the configured handwheel or electric and pneumatic devices for the product to be switched. Do not use the external force tools to cause damage to the valve. We turn the handwheel butterfly valve clockwise to turn it off, and vice versa.
