The function of flanged three-piece ball valve is mainly used to cut off or connect the medium in the pipeline. Flanged three-piece ball valves require only 90 degrees of rotation and a small moment of rotation to control the opening and closing of the valve. Tight flanged three-piece ball valves are mainly used in petroleum industry, chemical industry, pharmaceutical engineering, water conservancy engineering, iron and steel industry, electric power industry, etc. There is a strong shearing force between the V-shaped core of the flanged three-piece hard-sealed V-shaped ball valve and the metal seat of carbide. It is especially suitable for medium containing fibers and small solid particles.
Structural characteristics of flanged three-piece ball valve
1. Flanged connection three-piece ball valve has fire safety structure: flanged connection three-piece ball valve has fire safety function, and its design and manufacture follow the requirements of national standards.
2. Dual blocking and discharge function: Flanged three-piece ball valve uses spring pre-tightening floating seat. Whether the valve is fully open or fully closed, the upstream and downstream seats block the flow, and the flanged three-piece ball valve body cavity retained material is discharged through the discharge valve.
3. Automatic pressure relief function of flanged three-piece ball valve: When the abnormal pressure rise is caused by the temperature rise of the retaining medium in the body cavity of the flanged three-piece ball valve, it is not necessary to pass the safety valve, but can automatically relieve pressure only by the function of the valve seat, which is very important to ensure the safety of the valve when transporting liquid medium.
