The correct use, installation and maintenance of Ball Valves is very important, and it is also a content that heating companies must refer to when formulating operating procedures. Scientific management and maintenance of ball valves during the construction period can not only ensure safety, but also reduce construction and operation management. The cost of the period, mainly pay attention to the following aspects:

1. Use the correct method to load and unload the valve to avoid mechanical damage to the valve. When lifting the valve, the lifting strap cannot be tied to the valve stem or actuator for lifting. If the valve is operated in violation of regulations, it will cause the valve stem to bend, the valve stem seal failure and the turbine The box was destroyed.

2. Before the valve leaves the factory, blind plates or caps should be sealed on both ends of the valve to prevent water, sand, and other impurities on the construction site from entering the valve cavity during transportation and on the construction site, causing damage and corrosion to the seal.

3. At the construction site, the Valves should be placed neatly and should not be placed randomly, which will cause the valve drain valve or grease injection valve to be broken and damaged.

4. Before the welding construction of the fully Welded Ball Valve, confirm that the valve is welded in the fully open position to avoid welding spatter from causing damage to the ball and scratching the sealing surface. The welding temperature of the valve seat is controlled at 140 degrees.

5. After completing the water pressure test, drain the water from the valve cavity to prevent rust and icing.
