Yog tias koj tseem tsis paub meej tias yuav xaiv cov hlau forged steel gate valves lossis cov hlau cam khwb cia (WCB) gate valves, thov mus saib lub Hoobkas zfa valve kom paub txog qhov sib txawv tseem ceeb ntawm lawv.

1. Kev ntaus thiab kev pov yog ob txoj kev ua haujlwm sib txawv.

Kev Ua Phem: Cov hlau raug cua sov thiab yaj thiab tom qab ntawd nchuav rau hauv cov pwm xuab zeb lossis pwm. Tom qab txias, nws khov ua ib yam khoom. Cov qhov cua yooj yim tsim nyob rau hauv nruab nrab ntawm cov khoom.
Forging: Feem ntau siv cov txheej txheem xws li hammering ntawm qhov kub siab kom ua rau cov hlau ua ib qho workpiece nrog ib qho duab thiab qhov loj hauv lub xeev yas, thiab hloov nws cov khoom lub cev.

2. Qhov sib txawv ntawm kev ua tau zoo ntawm cov qhov rooj vag forged thiabWCB rooj vag valve

Thaum lub sijhawm forging, cov hlau raug hloov pauv yas, uas muaj cov nyhuv ntawm kev ua kom cov noob zoo, yog li nws feem ntau siv rau hauv kev tsim cov khoom tseem ceeb. Casting muaj qhov yuav tsum tau ua rau cov ntaub ntawv yuav tsum tau ua. Feem ntau, hlau cam khwb cia, txhuas, thiab lwm yam muaj cov khoom casting zoo dua. Casting tsis muaj ntau qhov zoo ntawm forging, tab sis nws tuaj yeem tsim cov khoom nrog cov duab nyuaj, yog li nws feem ntau siv rau hauv kev tsim cov khoom txhawb nqa uas tsis xav tau cov khoom siv kho tshuab siab.

2.1 Siab

Vim muaj qhov sib txawv ntawm cov khoom siv, cov hlau forged tuaj yeem tiv taus cov zog loj, thiab lawv cov plasticity, toughness thiab lwm yam khoom siv kho tshuab siab dua li cov ntawmWCB li qubYog li ntawd, nws tuaj yeem siv rau hauv cov xwm txheej ua haujlwm siab dua. Cov qib siab siv feem ntau ntawm cov hlau forged yog: PN100; PN160; PN250; PN320; PN400, 1000LB ~ 4500LB. Cov siab nominal siv feem ntau ntawm WCB li qub yog: PN16, PN25, PN40, 150LB ~ 800LB.

2.2 Txoj kab uas hla nominal

Vim tias cov txheej txheem forging muaj qhov xav tau siab ntawm cov pwm thiab cov khoom siv, lub cheeb ntawm cov forged li qub feem ntau yog qis dua DN50.

2.3 Muaj peev xwm tiv thaiv kev xau dej

Txawm hais tias cov txheej txheem nws tus kheej txiav txim siab los xij, kev casting feem ntau yuav tsim cov qhov cua thaum lub sijhawm ua haujlwm. Yog li ntawd, piv rau cov txheej txheem forging, lub peev xwm tiv thaiv kev xau ntawm cov khoom siv casting tsis zoo li cov khoom siv forged.
Yog li ntawd, hauv qee qhov kev lag luam uas muaj kev tiv thaiv kev xau siab, xws li roj, roj av, roj av, tshuaj lom neeg thiab lwm yam kev lag luam, cov hlau forged tau siv dav.

2.4 Qhov tsos

WCB li qub thiab forged steel li qub yooj yim kom paub qhov txawv ntawm qhov tsos. Feem ntau, WCB li qub muaj xim nyiaj, thaum forged steel li qub muaj xim dub.

3. Qhov sib txawv ntawm cov teb thov

Qhov kev xaiv tshwj xeeb ntawm WCB li qub thiab forged steel li qub nyob ntawm qhov chaw ua haujlwm. Nws tsis tuaj yeem hais dav dav txog cov teb twg siv forged steel li qub thiab cov teb twg siv WCB li qub. Kev xaiv yuav tsum raws li qhov chaw ua haujlwm tshwj xeeb. Feem ntau hais lus, WCB li qub tsis tiv taus kua qaub thiab alkali thiab tsuas yog siv tau rau ntawm cov kav dej ib txwm muaj, thaum forged steel li qub tuaj yeem tiv taus siab thiab tuaj yeem siv rau hauv qee lub Hoobkas uas muaj qhov kub siab, xws li cov chaw tsim hluav taws xob thiab cov chaw tsim tshuaj lom neeg. Chav kawm li qub.

4. Nqe

Feem ntau hais lus, tus nqi ntawm cov hlau forged li qub yog siab dua li ntawm WCB li qub.
