Cov ntsiab lus tseem ceeb thiab cov txheej txheem tsim khoom sib txawv (qhov tseem ceeb sib txawv)
1. Forged Pob Valve
Txheej Txheem Txheej Txheem: Sab nraud quab yuam (forging rauj, xovxwm, thiab lwm yam) yog siv rau cov hlau hlau (xws li steel ingots, puag ncig tuav), ua rau cov yas deformation ntawm qhov kub thiab txias, maj mam forging rau hauv ib qho dawb paug conforming rau lub valve zoo. Cov khoom tiav lawm ces tsim los ntawm machining, kev kho cua sov, thiab lwm yam txheej txheem. Cov yam ntxwv tseem ceeb yog "yas deformation forming," qhov twg cov nplej sab hauv ntawm cov hlau yog compacted thiab reconstructed vim forging, tsim nruam hlau ntws kab.
Txheej Txheem: Hlau billet cua sov → Forging / nias → Rough machining → Thaum tshav kub kub kev kho mob (los txhim kho lub zog) → Finish machining (sealing nto, threads, thiab lwm yam) → soj ntsuam thiab txais.
2. Npog Pob Valve
Txheej Txheem Txheej Txheem: Molten hlau (xws li cam khwb cia hlau, cam khwb cia hlau, stainless hlau) yog poured rau hauv pre- ua pwm kab noj hniav. Tom qab cov hlau molten cools thiab solidifies, qhov dawb paug raug tshem tawm thiab ua tiav ntxiv (xws li sib tsoo, drilling, txiav) los tsim lub valve. Cov yam ntxwv tseem ceeb yog "kua molding," tso cai rau kev tsim cov duab nyuaj hauv ib qho kev ua haujlwm. Txawm li cas los xij, cov teeb meem sab hauv tuaj yeem tshwm sim thaum cov hlau molten txias.
Cov txheej txheem zoo: Moulding (xuab zeb pwm, hlau pwm, thiab lwm yam) → Hlau smelting → Casting → Txias thiab demolding → Blank tu (tshem tawm risers thiab rooj vag, sib tsoo) → Machining → Tshuaj xyuas thiab txais.
Cov xwm txheej siv tau thiab qhov sib txawv ntawm tus nqi (cov qauv xaiv tseem ceeb)
1. Cov xwm txheej siv tau rau forged pob li qub
High-pressure/ultra-siab- siab tshuab: xws li siab- cov kav dej siab hauv cov nroj tsuag petrochemical thiab cov tshuab hluav taws xob hauv cov chaw tsim hluav taws xob (ua haujlwm siab tshaj lossis sib npaug li 10MPa), yuav tsum muaj peev xwm tiv taus huab cua siab thiab kub hloov pauv.
Kev ua haujlwm hnyav: Tsawg- qhov kub thiab txias (xws li LNG tsheb thauj mus los), corrosive media (xws li muaj zog acids thiab alkalis), thiab cov xwm txheej cuam tshuam nrog kev hloov pauv ntau zaus lossis cuam tshuam cov loads (xws li siab - siab kaw- tawm li qub thiab kev nyab xeeb li qub).
Cov me me -inch li qub: Feem ntau pom hauv pob li qub hauv qab DN50 (forging thev naus laus zis ua rau nws yooj yim dua los tswj qhov ntom ntawm me me - qhov loj me).
2. Cov xwm txheej siv tau rau Cast Ball Valves
Tsawg- thiab nruab nrab- cov tshuab siab: xws li cov dej hauv nroog thiab cov dej ntws tawm, cov kav dej cua sov, thiab cov tshuab dej dav dav dav dav (ua haujlwm siab tsawg dua lossis sib npaug li 6.4MPa).
Tsawg-tus nqi xav tau: xws li cov khoom siv zoo tib yam cam khwb cia hlau pob li qub (cov khoom siv qis, kev ua haujlwm siab casting, tsim nyog rau ntau lawm).
3. Tus nqi sib piv
Forged pob li qub: Kev siv cov khoom siv tsawg (forging tsim cov khoom pov tseg), ntau cov kauj ruam ua haujlwm, lub voj voog ntev dua, thiab cov nqi feem ntau yog 30% -50% siab dua li cov cam khwb cia ntawm tib yam tshwj xeeb (tus nqi sib txawv yog ntau dua rau cov khoom siv siab thiab cov khoom siv tshwj xeeb).
Cam khwb cia pob li qub: Kev siv cov khoom siv raw, nrawm nrawm tsim, haum rau kev tsim khoom loj, thiab tus nqi qis, tshwj xeeb tshaj yog rau cov khoom loj - txoj kab uas hla nrog cov nqi zoo.
Cov Txheej Txheem Xaiv Txheej Txheem
Los ntawm Kev Ntsuas Siab: Rau kev kub siab (Ntau dua lossis sib npaug ntawm 10MPa), forging yog nyiam; rau nruab nrab thiab qis siab (tsawg dua los yog sib npaug rau 6.4MPa), casting yog siv tau.
Los ntawm Kev Ua Haujlwm Degree: Forging yog nyiam rau corrosive, qis-kub, thiab cuam tshuam-load scenarios; casting yog nyiam rau qhov qub qub - kub thiab tsis yog - cuam tshuam scenarios.
Los ntawm Valve Diameter: Forging yog superior rau me me diameters (DN50 thiab hauv qab); casting yog kev lag luam ntau dua rau cov kab loj loj (DN300 thiab siab dua).
Los ntawm Kev Ntsuam Xyuas Cov Cai: Rau cov xwm txheej uas yuav tsum tsis yog -kev kuaj kev puas tsuaj (UT/RT) thiab xoom qhov tsis xws luag, forging yog qhov zoo dua (casting yog qhov nyuaj dua los kuaj xyuas qhov tsis xws luag).
