Three-piece Ball Valve
Introduction:
The three-piece ball valve is connected by internal thread, and the valve body is composed of three parts. It is usually used for relatively large and important valves.
The three-piece ball valve is composed of three parts, the bonnet on both sides and the middle valve body. The difference between the three-piece ball valve and the two-piece ball valve is that it is easy to disassemble and maintain. Stronger pressure resistance.
Advantage:
1. The fluid resistance is small, and its resistance coefficient is equal to the pipe section of the same length.
2. Simple structure, small size and light weight.
3. Tight and reliable, the sealing surface material of the ball valve is widely used plastic, with good sealing performance, and it has also been widely used in vacuum systems.
4. Easy to operate, open and close quickly, just rotate 90° from fully open to fully closed, which is convenient for long-distance control.
5. It is easy to maintain, the ball valve has a simple structure, the sealing ring is generally movable, and it is more convenient to disassemble and replace.
6. When fully open or fully closed, the sealing surfaces of the ball and the valve seat are isolated from the medium, and when the medium passes through, it will not cause erosion of the valve sealing surface.
7. Wide range of applications, diameters ranging from small to several millimeters, large to several meters, and can be applied from high vacuum to high pressure.
