Structural Features Of Ball Valves
1. No friction between opening and closing.
This function completely solves the problem that the traditional valve affects the seal due to the friction between the sealing surface. 2. Mounted structure.
Valves mounted on pipes can be checked and repaired directly online, which can effectively reduce device parking and reduce costs. 3. Single seat design.
It eliminates the problem that the cavity medium of the valve affects the safety of use due to abnormal boost. 4. Low torque design.
Special structure design of the stem, just with a small handwheel valve can be easily opening and closing. 5. Wedge-shaped sealing structure.
The valve is based on the mechanical force provided by the stem, the ball wedge is pressed to the seat and sealed, so that the sealing of the valve is not affected by the change in the pipeline pressure difference, in a variety of operating conditions have a reliable guarantee of sealing performance. 6. Self-cleaning structure of the sealing surface.
When the sphere is tilted away from the seat, the fluid in the pipeline passes evenly through the spherical sealing surface, which not only eliminates the local scour of the seat by the high-speed fluid, but also washes away the accumulation on the sealing surface to achieve the purpose of self-cleaning.
