The three piece ball valve has the following advantages:1. The fluid resistance is small, and its resistance coefficient is equal to that of a pipe segment 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 in plastic, with good sealing performance, and has also been widely used in vacuum systems.
4. Easy to operate, quick to open and close, with only a 90 ° rotation from full open to full close, facilitating remote control.
5. Easy to maintain, the ball valve has a simple structure, and the sealing ring is generally movable, making disassembly and replacement more convenient.
6.When fully open or fully closed, the sealing surfaces of the ball and valve seat are isolated from the medium. When the medium passes through, it will not cause erosion of the valve sealing surface.
7. It has a wide range of applications, with diameters ranging from a few millimeters to several meters, and can be applied from high vacuum to high pressure.
Aatters needing attentionThe installation and maintenance of ball valves should pay attention to the following matters:
1. Leave a position for the valve handle to rotate
2. Cannot be used for throttling
3. Ball valves with transmission mechanisms should be installed upright.
Structural characteristics1. No friction during opening and closing. This feature completely solves the problem of traditional [wiki] valves [/wiki] affecting sealing due to friction between sealing surfaces
2. Top mounted structure. Valves installed on pipelines can be directly inspected and repaired online, which can effectively reduce device downtime and lower costs.
3. Single seat design. Eliminated the problem of abnormal pressure rise in the chamber medium of the valve, which affects the safety of use.
4. Low torque design. The valve stem with a special structural design can be easily opened and closed with just a small handwheel valve.
5. Wedge sealing structure. Valves rely on the mechanical force provided by the valve stem to press the ball wedge onto the valve seat and seal, ensuring that the sealing performance of the valve is not affected by changes in pipeline pressure difference, and reliable sealing performance is guaranteed under various working conditions.
6. Self cleaning structure of sealing surface. When the sphere tilts away from the valve seat, the fluid in the pipeline passes uniformly along the sealing surface of the sphere at a 360 ° angle, which not only eliminates the local scouring of the valve seat by high-speed fluid, but also washes away the accumulation on the sealing surface, achieving the purpose of self-cleaning.
