A ball valve is a fluid control valve that can control the opening and closing of the fluid by rotating the ball. Normally, the ball valve can be fully closed or fully opened to ensure the tightness of the fluid. However, if the ball valve cannot be fully closed after turning, there may be several reasons:
1. Damaged seal ring:
The ball valve uses a seal ring to ensure the tightness of the fluid. If the seal ring is damaged or aged, it will cause the ball valve to be unable to be fully closed. In this case, the seal ring needs to be replaced to repair the ball valve.
2. Dirt or impurities:
If there is dirt or impurities accumulated inside the ball valve, it will also cause the ball valve to be unable to be fully closed. In this case, it is necessary to clean the inside of the ball valve to ensure that there are no obstacles interfering with the rotation of the ball.
3. Locking or jamming:
The rotating parts of the ball valve may be locked or jammed, resulting in an inability to fully close. This may be caused by damaged parts or improper installation. The rotating parts of the ball valve need to be checked and any damaged parts need to be repaired or replaced.
In short, if the ball valve cannot be completely closed, it is necessary to check the seal ring, clean the inside of the ball valve and check the rotating parts to determine the problem and take appropriate repair measures. If the problem cannot be solved, Detsen recommends consulting a professional valve repair service.
