产品结构特点 Construction features

1、中線蝶閥爲整個蝶板與閥座在360°圓周內同心(中線),具有雙向密封功能,壓力、流量可自由調節;
2、偏心蝶閥爲二維方向偏心産品的凸輪效應會使密封副産生足夠的密封比壓,並且隨著工作壓力的升高,密封效果更理想;
 3、四級加載彈性密封,保證了閥門內、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、采用可彈性墊片定位准確,結構簡單。(*采用O型圈是爲了防止意外泄漏時的安全措施)。
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.
