Ob chav Eccentric Design
Thawj Eccentricity: Lub valve ncej yog offset los ntawm nruab nrab ntawm lub phaj npauj npaim, txo kev sib txhuam ntawm tus npauj npaim phaj thiab lub rooj zaum valve thaum qhib thiab kaw.
Thib ob Eccentricity: Lub valve ncej yog offset los ntawm qhov chaw ntawm lub valve lub cev sealing nto, ua tiav sai disengagement thaum qhib thiab kaw.
Cov nyhuv: Lub phaj npauj npaim sai sai tshem tawm ntawm lub rooj zaum ntawm lub rooj zaum tom qab qhib, tshem tawm cov compression thiab scraping ntau dhau, txo qhov hnav, thiab txhim kho lub rooj zaum valve. Qee cov qauv siv hlau tawv seals (xws li stainless hlau, tawv alloy), tiv taus kub thiab siab siab (tsawg dua lossis sib npaug li 425 degree, PN16-PN25).
Flange kev twb kev txuas
Flange kev twb kev txuas yog siv, muab ib tug ruaj khov qauv, zoo sealing kev ua tau zoo, thiab yooj yim installation thiab disassembly. Nws yog tsim rau nominal diameters ntawm DN50-DN4500 thiab ua raws li cov qauv xws li GB / T12238 thiab API609.
Hom sealing
Soft Seal: Cov ntaub ntawv xws li roj hmab thiab PTFE, haum rau qhov kub thiab txias tsis tshua muaj siab (tsawg dua lossis sib npaug li 160 degree), nrog rau kev ua tau zoo sealing tab sis tsis muaj qhov kub thiab txias.
Hlau Hard Seal: Cov ntaub ntawv xws li stainless hlau thiab tawv alloy, resistant rau kub thiab siab, tab sis sealing kev ua tau zoo nyob ntawm machining precision.
Bidirectional sealing: Qee cov qauv ua tiav bidirectional xoom xau los ntawm cov qauv kev them nyiaj ntab, hloov mus rau cov kev hloov pauv hauv kev tshaj tawm ntws.
