Daily maintenance of buried fully welded ball valve

    The good technical characteristics of the buried fully welded ball valve make the entire gas pipeline become one (all welded), which strengthens the overall stress resistance of the pipeline (including the valve) and the ability to resist geological disasters (such as geological collapse) and reduce The possibility of air leakage is reduced and the reliability of the valve is improved.

    The installation and maintenance of the buried fully welded ball valve is very convenient. Its daily maintenance includes the maintenance of the valve seat cavity and the auxiliary gas main line.

    1. The valve seat cavity is the most easily infected area of the pipeline valve. In order to ensure the free movement of the valve seat, it should be cleaned once a year. The sealing of the valve can be checked regularly through the drain nozzle.

    2. The valve of the auxiliary gas main line is often rarely adjusted. It should be opened and closed at least once a year and an appropriate amount of smooth grease should be injected to prevent the glue between the ball and the valve seat and the friction between the valve ball and the valve seat.

    In addition to the daily maintenance of the buried fully welded ball valve, its correct operation and use method is also very important for its performance. If the operation is improper, it will cause impurities to collect on the valve seat or the surface of the valve ball, causing the valve seat to be embedded The body part is worn, which affects its performance.

    In operation, the buried fully welded ball valve should pay attention to the requirements of the opening and closing time, and it should be kept within an appropriate range. In addition, it should not be in the semi-open or semi-closed position during operation, but should be fully open or fully closed.
