Detailed Description of 2 Piece Stainless Steel Ball Valve
The 2 piece stainless steel ball valve
is a valve that rotates around the centerline of the valve body to open and close. The ball valve is mainly used in the pipeline to cut, distribute and change the flow direction of the medium. Ball valve is a new type of valve widely used in recent years, which has the following advantages:
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe length of the same length.
2. Simple structure. It is small in size and light in weight.
3. It is close and reliable. At present, the sealing surface material of the ball valve is widely used in plastic and has good sealing performance. It has also been widely used in vacuum systems.
4. The operation is convenient, the opening and closing is rapid, and the rotation is 90° from full opening to full closing, which is convenient for long-distance control.
5. The maintenance is convenient, the ball valve has a simple structure, and the sealing ring is generally movable, and the disassembly and replacement are relatively convenient.
6. When fully open or fully closed, the sealing surface of the ball and the valve seat is isolated from the medium, and the medium does not cause erosion of the sealing surface of the valve.
7. It has a wide range of applications. It is suitable for use from small to a few millimeters and as large as a few meters. It can be applied from high vacuum to high pressure.
2 piece stainless steel ball valve can be divided into straight-through, three-way and right-angle types according to their channel positions. The latter two ball valves are used to distribute the medium and change the direction of the medium. The following items should be noted for the installation and maintenance of 2 piece stainless steel ball valve:
1. Leave the position where the valve handle rotates.
2. It cannot be used for throttling.
3. The ball valve with transmission mechanism should be installed upright.
