Lub qhov dej txhaws
Hauv txhua qhov khoom siv caij nplooj ntoos hlav ntau dua li lub caij nplooj ntoos hlav valve ntawm cov khoom yuav tsum yog nruj dua, tshwj xeeb tshaj yog kev ntxhov siab siab thiab ntu ntu ntawm lub caij nplooj ntoos hlav valve ntawm cov khoom yuav tsum yog ze li ntawm:
Lub zog loj: tensile lub zog 2000MPa.
Zoo tshaj qhov zoo: nto tsis tso cai rau ua tiav decarburization, ib nrab sib sib zog nqus decarburization ntawm tsis muaj ntau tshaj 0.5% ntawm lub xaim taub, qhov chaw tsis muaj qhov tob tsis tshaj 40 microns, kom ua tau raws li cov cai ntawm cov hlau xaim hauv txoj kev ua kev machining, nto nti thiab dhau los ntawm ob txoj kev (los ntawm hom thiab cov kab kev sib hloov teb viav viav tam sim no qhov khuam kom tsis raug, qhov tsis xws luag tsis siv neeg cov tshuaj tsuag logo.
Ultra-purity: cov kab sib xyaw ntawm oxides thiab sulfides yog txog qib 0, thiab cov ntsiab lus ntawm oxygen thiab nitrogen raws li tooj liab, txhuas thiab titanium hauv cov ntaub ntawv yuav tsum muaj kev tswj hwm. Yog li ntawd, kev tsim cov dej ntawm lub caij nplooj ntoo hlav steel xav tau tswj tau los ntawm qhov chaw ntawm smelting.
Kev tiv thaiv zoo los tiv thaiv kev so: lub caij nplooj ntoos hlav valve yuav tsum tau nyob hauv kev pabcuam ntev ntev ntawm 120 ~ 150 ℃ nrog load attenuation tsawg dua 5%.
Lub zog ntawm kev sib txawv: lub zog ntawm tib lub disk cov khoom sib txawv tsis ntau tshaj 140MPa, cov duab puab hla cov khoom siv xws li oval ntu ntu ntawm qhov curvature ntawm cov voj voog sib txawv tangent point, elliptical cross seem ntawm qhov ntev thiab ntev ntawm lub axis muaj qhov tshwj xeeb Cov.
