Txheej txheem tsim ntawm cov tshev valve

(1) Kev tswj kom zoo ntawm lub ntsiab dawb paug: Txhua qhov ntawm lub valve no yog forgings, thiab forging yog nruj me ntsis raws li cov txheej txheem forging specifications thiab txheej txheem phaib. Qhov pib thiab xaus forging kub, deformation degree, thiab deformation ceev yog nruj me ntsis tswj, thiab txias yog nqa tawm raws li lub txias txoj kev teev nyob rau hauv cov txheej txheem specifications. Kev tshuaj xyuas tshuaj muaj pes tsawg leeg, kev ntsuas kev ua tau zoo, kev ntsuas kev sib xyaw ua ke, thiab kev tshuaj xyuas cov qauv metallographic tau ua los ntawm cov khoom siv forged, thiab tom qab kev tshuaj xyuas, kuaj, thiab ntsuas, lawv txhua tus ua tau raws li cov qauv sib xws.

Qhov zoo ntawm forgings yog ensured los ntawm kev soj ntsuam ultrasonic thiab kua penetrant tshuaj xyuas. Raws li cov kev cai ntawm RCC-M, 100% ultrasonic kuaj thiab kev soj ntsuam yog nqa tawm ntawm forgings, thiab kua penetrant tshuaj xyuas thiab ntsuam xyuas yog nqa tawm nyob rau hauv tag nrho cov nto ntawm forgings.

(2) Txhawm rau txhim kho qhov vuam zoo, plasma argon arc vuam tshuab yog siv rau vuam ntawm qhov sib khi ntawm lub valve disc thiab lub rooj zaum valve. Nyob rau tib lub sijhawm, kom ntseeg tau tias vuam zoo, cov txheej txheem vuam siv hauv kev tsim khoom tau raug tshuaj xyuas dua.

(3) Kev sib sau ua ke ntawm cov khoom lag luam zoo tsis yog tsuas yog yuav tsum muaj cov khoom ua tau zoo, tab sis tseem ceeb tshaj, yuav ua li cas los sib sau cov khoom ua tau zoo rau hauv cov khoom ua tau zoo. CNNC Suvalve tau teeb tsa ib qho kev paub dhau los thiab kev txawj ntse los ua ke thiab pab pawg neeg paub daws teeb meem tsim los ntawm ntau tus kws tshaj lij thiab cov kws tshaj lij laus, lub luag haujlwm rau kev sib dhos, kev debugging, thiab kuaj cov li qub. Lawv tau tsim cov txheej txheem ntxuav thiab sib dhos rau cov khoom siv, nruj me ntsis tswj thiab siv zog ua kom zoo tshaj plaws hauv kev sib dhos thiab kev debugging, kom ntseeg tau tias kev sib dhos ua tiav thiab kev debugging ntawm li qub. Ntau yam kev ntsuas kev ua tau zoo tau ua tiav, thiab txhua qhov ntsuas tau ua tau raws li qhov xav tau ntawm phau ntawv tsim ua haujlwm.

(4) Kev soj ntsuam txheej txheem tau tsim ib txoj kev npaj zoo rau cov li qub kom muaj kev tswj xyuas zoo los ntawm cov khoom siv raw, cov khoom siv raw khoom, kev siv tshuab, vuam, kev kho cua sov, kev kuaj tsis muaj kev puas tsuaj, kev tu, kev sib dhos, kev kuaj lub Hoobkas, thiab ntau yam kev xeem, thiab muaj tau lees paub thiab ua pov thawj ntawm qhov chaw los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tshawb Fawb Thib Ob thiab Tsim Kev Lag Luam Nuclear.
