Common faults and solutions of ball valves

Common faults and solutions of ball valves

Ball valve is a commonly used valve widely used in various industrial fields. However, ball valves also have some common faults that may affect their normal operation. Next, we will introduce common faults and solutions of ball valves.
1、 Ball valve leakage fault and solution:
1. Leakage at the bottom of the ball valve: This may be caused by aging or damage to the sealing ring. The solution is to replace the sealing ring and ensure that it is installed correctly.
2. Leakage at the joint of the ball valve: If the connection between the ball and the joint is not tight, it will cause leakage. The solution is to check the connection between the sphere and the joint, ensure a tight connection, and use appropriate sealing materials to fill the gaps.
3. Leakage at the packing of the ball valve: Leakage at the packing may be caused by aging or damage of the packing. The solution is to replace the packing and ensure that the packing is installed correctly.
2、 Ball valve oil leakage fault and solution:
1. Oil leakage at the bottom of the ball valve: This may be caused by aging or damage to the sealing ring. The solution is to replace the sealing ring and ensure that it is installed correctly.
2. Oil leakage at the ball valve joint: If the connection between the ball and the joint is not tight, it will cause oil leakage. The solution is to check the connection between the sphere and the joint, ensure a tight connection, and use appropriate sealing materials to fill the gaps.
3. Oil leakage at the packing of the ball valve: The oil leakage at the packing may be caused by aging or damage of the packing. The solution is to replace the packing and ensure that the packing is installed correctly.
3、 Malfunctions and solutions for ball valves that cannot be opened or closed:
1. Ball valve cannot open: This may be due to excessive friction between the ball and the sealing ring. The solution is to check the friction between the ball and the sealing ring, and lubricate with appropriate lubricant.
2. Difficulty in closing the ball valve: This may be due to excessive friction between the ball and the joint. The solution is to check the friction between the ball and the joint, and lubricate it with appropriate lubricant.
4、 Malfunctions and solutions of insensitive ball valve operation:
1. Inadequate ball valve operation: This may be due to loose or damaged connections between the operating rod and the ball. The solution is to check the connection between the operating rod and the sphere, ensure a tight connection, and repair or replace damaged components.
2. Inadequate ball valve operation: This may be caused by carbon or dirt accumulation inside the ball. The solution is to clean the carbon or dirt inside the sphere and lubricate it with appropriate lubricant.
The above is a brief introduction to common faults and solutions of ball valves. In practical applications, further maintenance or replacement of components may be necessary depending on the specific fault situation. When maintaining the ball valve, we should regularly check the working status of the ball valve, promptly handle any faults found, and ensure the normal operation of the ball valve.
