(1) Kev tswj xyuas qhov ua tau zoo ntawm qhov tseem ceeb ntawm txhua qhov ntawm lub valve yog kev zam txim, forged nruj me ntsis raws li cov txheej txheem forging thiab daim npav khiav lag luam, nruj tswj hwm qhov kub ntawm qhov pib forging, qhov kawg forging kub, deformation degree thiab deformation ceev, raws li txoj kev txias txias stipulated los ntawm txheej txheem txheej txheem. Kev tshuaj lom neeg muaj pes tsawg leeg tshuaj ntsuam, kev ntsuas cov cuab yeej lub zog, kev ntsuas tshuaj intergranular corrosion thiab kev tsom xam cov duab hluav taws xob tau ua kom tau raws li cov qauv coj ua.
Cov kev ua tau zoo ntawm kev zam txim yog ua tiav los ntawm kev soj ntsuam ultrasonic thiab kuaj kev nqus kua, ua raws li RCC-M cov cai rau 100% ultrasonic qhov khuam pom thiab kev ntsuas kev zam txim, thiab kuaj thiab ntsuas txhua qhov chaw ntawm kev zam txim.
(2) Vuam nyob rau hauv thiaj li yuav txhim kho qhov zoo ntawm nthwv dej, qhov chaw sib khi ntawm lub disc thiab valve lub rooj adopts plasma argon arc vuam txheej txheem. Nyob rau tib lub sijhawm, txhawm rau xyuas kom lub vuam zoo, cov txheej txheem siv vuam siv hauv ntau lawm yog rov soj ntsuam dua.
(3) Kev sib sau ua ke cov khoom siv tsis yog tsuas yog xav tau qhov ntsuas ntawm qhov ntsuas siab nkaus xwb, tabsis tseem yuav ua li cas dhos cov yeeb yaj kiab high-precision tso ua ke rau cov khoom lag luam zoo. Lub hauv paus nuclear-Soviet valve teeb tsa cov kev paub dhau los, ua haujlwm thev naus laus zis, tsim ntawm ntau tus kws tshaj lij thiab cov kws tshaj lij. Cov pab pawg ua haujlwm, lub luag haujlwm rau lub rooj sib txoos valve, kev ua haujlwm, kev kuaj xyuas, kev txhim kho ntawm cov txheej txheem ntawm kev ntxuav tu, txheej txheem sib dhos, hauv kev sib dhos thiab cov tswv yim nruj, zoo tshaj plaws, kom ntseeg tau tias lub rooj sib dhos valve, ua haujlwm tiav, thiab ua tiav ntau yam kev ntsuas, cov ntsuas yog nyob rau hauv nrog cov haujlwm tsim tsim.
(4) Cov txheej txheem tshuaj xyuas lub valve tsim cov phiaj xwm zoo kom paub meej tias lub valve los ntawm cov khoom siv raw, cov khoom siv khoob, kev siv tshuab, vuam, kev kho cua sov, kev kuaj tsis raug, kev ntxuav, kev sib dhos, kev sim khoom thiab txhua hom kev kuaj yog kev tswj zoo, thiab lub koom haum nuclear Kev Tshawb Fawb Kev Tshawb Fawb Ob Chav Koom Tes lees paub thiab ua pov thawj nyob.
