General understanding of rolling bearing used in ball valve

2020-07-07 13:51:22

We usually use ball valve in our daily life work, but we know what is the summary of rolling bearing used in ball valve? Then I'll give you a specific explanation. I hope it will help you a lot.

Ball valve is widely used in petroleum refining, long-distance pipeline, chemical industry, papermaking, pharmaceutical, water conservancy, electric power, municipal administration, steel other industries. The fluid resistance is small. The full-size ball valve has almost no flow resistance is tight reliable. However, the opening closing torque of ball valve is one of the important parameters reflecting the performance of ball valve. It refers to the force torque required to be applied when the valve is opened closed The action of a comprehensive technical index under the action of mass pressure. With the development of the times, after entering the 21st century economy, with the remarkable optimization improvement of production manufacturing technology, in order to reduce the opening closing torque reduce the cost of ball valves, rolling bearings are applied in ball valves, which significantly reduces the opening closing torque, prolongs the service life improves the operability significantly.

In large diameter fixed ball valves such as ball valves for slurry transportation ball valves for coal water slurry service, the valve stem adopts dust-proof anti ejection design. In structure, the valve stem can only bear the opening closing moment of the valve. The thrust of the medium is carried by the upper lower support bearings to ensure that the valve stem can work reliably for a long time. The upper lower supporting shafts are equipped with rolling bearings sliding bearings, so as to reduce the operating force of the valve Moment. For small diameter floating ball valve, rolling bearing sealing ring are designed at stem journal.

The above is to introduce the ball valve ball bearings in the general understanding of the relevant content, I hope to help you. If you want to know more about low temperature stop valve, please continue to pay attention to us, we look forward to your call.
