2、偏心蝶閥為二維方向偏心產(chǎn)品的凸輪效應(yīng)會(huì)使密封副產(chǎn)生足夠的密封比壓,并且隨著工作壓力的升高,密封效果更理想;
3、四級(jí)加載彈性密封,保證了閥門(mén)內(nèi)、外的零泄漏。
a:軸與蝶閥一體外襯F46;
b:軸頭端面采用彈性O(shè)型圈和軸肩處剛性墊圈、彈性橡膠墊組合;
c:軸的徑向采用O型圈與金屬軸套的組合;
d:閥座鑲嵌有彈性條的閥體槽內(nèi)。
4、采用可彈性墊片定位準(zhǔn)確,結(jié)構(gòu)簡(jiǎn)單。(*采用O型圈是為了防止意外泄漏時(shí)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.
