high-Pressure Ball Valves Manufacturers introduces the maintenance knowledge of ball valves:
1. Periodically check the tightness of the valve, and check it through the sewage nozzle. If there is internal leakage, complete the treatment according to the internal leakage treatment procedure;
2. Inject a certain amount of fresh lubricating grease into the valve seat in a timely manner. The amount and frequency of injection are determined according to the frequency of valve movement. Generally, after the valve moves once, an appropriate amount of lubricating grease should be injected. 1/8 of the system volume, the purpose of doing this is to prevent impurities in the pipeline from entering the back cavity of the valve seat to a large extent, affecting the movement of the valve seat, resulting in seal failure, and at the same time ensuring that the sealing surface is always in a "wet" state;
3. For valves that seldom move, move less once a year, and at the same time inject an appropriate amount of grease. This can prevent the ball and the valve seat from gluing, and at the same time prevent dry grinding when the ball moves, and protect the seat and the valve seat. Sphere:
4. Carry out comprehensive protection and maintenance of the ball valve before winter, and the key point is to drain the water in the valve cavity and the actuator to prevent thawing in winter and affecting the abnormal function;
5. Replace the grease in the gear transmission mechanism once a year;
6. Check the valve diameter seal regularly, and deal with it in time if any leakage occurs;
7. Eliminate rust and protect the exterior.
