2、偏心蝶阀为二维方向偏心产品的凸轮效应会使密封副产生足够的密封比压,并且随着工作压力的升高,密封效果更理想;
3、四级加载弹性密封,保证了阀门内、外的零泄漏。
a: 轴与蝶阀一体外衬F46;
b: 轴头端面采用弹性O型圈和轴肩处刚性垫圈、弹性橡胶垫组合;
c: 轴的径向采用O型圈与金属轴套的组合;
d: 阀座镶嵌有弹性条的阀体槽内。
4、采用可弹性垫片定位准确,结构简单。(*采用O型圈是为了防止意外泄漏时的安全措施)。
1, the center line butterfly valve for the whole of the butterfly plate and valve seat in 360 ° circumferential concentric (middle), have two-way sealing function, pressure and flow rate can be adjusted freely;
2. The CAM effect of eccentric butterfly valve in the 2d direction eccentric product will make the sealing side produce sufficient sealing ratio pressure, and the sealing effect is more ideal as the working pressure increases.
3. Four-level loading elastic seal ensures zero leakage inside and outside the valve.
A: the shaft and butterfly valve are lined with F46;
B: the shaft end adopts the elastic o-ring and the axial shoulder rigid washer and elastic rubber pad;
C: the radial direction of the shaft adopts the combination of o-ring and metal bushing;
D: seat inlaid with elastic strip.
4. The elastic gasket is used to position accurately and the structure is simple. * use O rings to prevent accidental leaks.
