How to solve the poor sealing of ball valves?

As a key equipment in the field of fluid control, the sealing performance of ball valves is crucial. Once the sealing performance of the ball valve is poor, it will not only cause medium leakage and affect production safety, but also lead to resource waste and environmental pollution. So, how can we solve the problem of poor sealing of ball valves?

The poor sealing performance of ball valves may be due to aging of the seals. During long-term use of ball valves, sealing components such as rubber rings and gaskets will gradually age, harden, and lose elasticity due to corrosion of the medium, temperature changes, and frequent switching operations, making it difficult to tightly fit the ball and valve seat, resulting in leakage. At this point, new seals should be replaced promptly, and high-quality sealing materials that are compatible with the medium, corrosion-resistant, and heat-resistant should be selected to ensure the sealing effect.

Improper installation of ball valves can also affect their sealing performance. If the ball valve is not installed in the correct direction and position during installation, or if uneven force is applied during installation, resulting in a deviation in the fit between the ball and the valve seat, it will prevent the sealing surface from fully fitting and cause leakage. Therefore, when installing the ball valve, it is necessary to strictly follow the installation instructions to ensure that the installation direction of the ball valve is correct, the installation force is uniform, and the concentricity between the ball and the valve seat is guaranteed.

In addition, impurities inside the ball valve can also damage its sealing performance. Impurities such as particles and rust in the medium may enter the interior of the ball valve, get stuck between the ball and the valve seat, scratch the sealing surface, and affect the sealing effect. Regular cleaning and maintenance of ball valves to remove internal impurities can effectively prevent such situations from occurring. Filters can be installed at the inlet and outlet of the ball valve to intercept impurities in the medium and reduce the chance of impurities entering the ball valve.

In short, solving the problem of poor sealing of ball valves requires starting from multiple aspects and taking corresponding measures for different reasons to ensure the normal operation of ball valves and ensure smooth production.
