Ball valve and plug valve belong to the same type of valve. The opening and closing part of the ball valve is a circular sphere. Influence. So what is the opening and closing direction of the ball valve?
Structure diagram and switch direction picture of ball valve
As shown in the above figure, the direction of the ball valve switch:
1. Drive the ball to the left through the valve stem, rotate it by 90 degrees, and all the ball valves will be opened.
2. Drive the ball to the right through the valve stem, rotate it for 90 degrees, and all the ball valves will be closed.
The function of ball valve in pipeline is to cut off, distribute and change the flow direction of medium. In recent years, ball valves have been widely used. Compared with other valves, ball valves have their own advantages:
Advantages of ball valve:
1. The fluid resistance is small, and its resistance coefficient is equal to that of the pipe section with the same length.
2. Tight and reliable, the sealing performance of the ball valve is better than that of the butterfly valve. In some pipelines that need to be sealed, ball valves have more advantages.
3, simple operation, fast opening and closing, only need to rotate 90 degrees from full opening to full closing, and can be equipped with pneumatic and electric driving devices, which is convenient for remote control.
4, convenient maintenance, simple ball valve structure, generally movable sealing ring, more convenient for disassembly and replacement.
6. When the ball valve is fully opened or closed, the sealing surface between the ball and the valve seat is isolated from the medium, and the sealing surface of the valve will not be eroded when the medium passes.
7. The scope of application is wider. The diameter of the ball valve is as small as a few millimeters and as large as several meters. It can be applied to media from vacuum to high pressure.
Nowadays, ball valves have been widely used in petroleum, chemical industry, power generation, paper making, heat and other fields. The demand for ball valves is huge. If you need to purchase ball valve products, you can contact us.
