进口硬密封蝶阀原理特点

进口硬密封蝶阀采用三偏心多层次金属密封结构,无机械磨损,可达到零泄漏,有优良的双向密封功能,使用于石油、化工、冶金、电力、食品、医药、给排水、气体输送等不同介质的管路上作调节流量、截断或接通流体的最佳装置。选用不同的材质,可分别适用于水、污水、海水、空气、蒸汽、煤气、可燃气体、腐蚀性介质、油品及食品等介质,最高工作温度可达600℃。
The Thomas triple offset butterfly valve offers excellent shutoff capabilities, with the low torque and reduced wear benefits of a triple offset design. The laminated disc seal, in conjunction with the triple offset geometry, results in a design that can provide bidirectional,bubble-tight shutoff.
