Stainless steel ball valve is a kind of valve with easy opening and closing, small size, reliable sealing and simple structure. It is the same type of valve as the plug valve, only the closing part is a ball, and the purpose of opening and closing is achieved by rotating the ball around the center line of the valve body.
The maintenance of stainless steel ball valves has always been a very important point, both in use and in storage. If it is not kept well, it is likely to cause corrosion and rust. How should stainless steel ball valves be maintained and maintained? Let’s listen to Junkai Valve’s introduction for you.
1. Regularly check the pipeline to ensure that there are no impurities such as rust and welding slag on the surface.
2. Regularly check the support.
3. The air source must not be faulty.
4. If the gasket at the joint between the valve body and the upper bonnet has been used for a long time, it should be replaced in time. When replacing, you only need to remove the bonnet to install a new gasket.
5. Once leakage is found in the stuffing box, it should be replaced in time. When replacing, the valve stem should be disengaged, and the pressure plate and packing gland can be removed to install new packing.
6. Regularly overhaul it.
7. If it is not used for long-term storage, a protective cover for the connecting flange should be installed, so the interface is all plugged with plastic plugs, and the overall vertical or horizontal position of the valve should be ensured when parking.
8. Do not support the valve on sensitive parts, such as valve positioners, joints, connecting lines, etc.
The above is an introduction to the maintenance of stainless steel ball valves.
