Operation and use of ball valves and analysis of common faults
First, the use of ball valve
A ball valve is a valve that uses a sphere to control the passage of fluid. His work is relatively simple and is mainly divided into two stages: opening and closing.
1. Opening operation: slowly rotate the valve shank so that the sphere is parallel to the valve seat channel, and the liquid can pass smoothly at this time.
2. Closing operation: Turn the valve knob in the reverse direction so that the sphere fits snugly to the valve seat to prevent the liquid from passing through.
During use, you should ensure smooth and slow operation to avoid sudden opening and closing caused by exposure to fluid and damage to the valve. At the same time, it is necessary to regularly check the tightness of the ball valve to make sure that it is working properly.
Second, common ball valve faults
1. Leakage: The ball valve seal performance is reduced, resulting in liquid leakage. Possible causes include ball and valve seat wear, seal ring aging, etc. D. The solution is to replace worn parts, regular inspection and maintenance.
2. Rotary caton: The rotation of the valve shank is not flexible, which may make it difficult to open or close. The cause may be rust or dust in parts such as the valve shank and bearing. The solution is to lubricate bearings, remove dust or replace rusty parts.
3. Working torque too much: Too much resistance to overcome when opening or off. A possible cause is the accumulation of impurities and valve wear between the valve sphere and the valve seat. The solution is to clean up impurities, repair or replace valves.
4. The valve cannot be opened or turned off: maybe the valve is stuck due to long-term use. The solution is to check and replace wear parts inside the valve, such as the O-ring and support seats.
5. Valve weakening: Due to long-term use or improper installation may cause the valve to loosen. The solution is to re-install the mount and check regularly.
Third, summary
The ball valve, as a common liquid control device, is relatively easy to operate, but still need to pay attention to the details during use to avoid sudden opening and closing and excessive effort. For common faults such as leakage, rotating katon, etc. D., Timely inspection and repair is required. During the repair, attention should be paid to the replacement of worn parts, cleaning of impurities, and regular inspection and maintenance to ensure the normal operation of the ball valve. In addition, correct installation and use are also the key to preventing failures. I hope that this article will help you better understand the operation and use of ball valves and the handling of common faults.
