Yog tias koj tseem tab tom xav seb puas yuav xaiv forged steel rooj vag li qub lossis cam khwb cia hlau (WCB) lub rooj vag li qub, thov mus saib zfa valve Hoobkas los qhia qhov sib txawv loj ntawm lawv.

1. Forging thiab casting yog ob txoj kev sib txawv.

Casting: Cov hlau yog rhuab thiab melted thiab ces poured rau hauv ib tug xuab zeb pwm los yog pwm. Tom qab txias, nws solidifies rau hauv ib yam khoom. Cua qhov yog yooj yim ua nyob rau hauv nruab nrab ntawm cov khoom.
Forging: Feem ntau yog siv txoj hauv kev xws li hammering ntawm qhov kub thiab txias los ua cov hlau rau hauv ib qho chaw ua haujlwm nrog cov duab thiab qhov loj me hauv lub xeev yas, thiab hloov nws lub cev.

2. Qhov sib txawv ntawm kev ua haujlwm ntawm forged gate li qub thiabWCB rooj vag valve

Thaum lub sij hawm forging, cov hlau undergoes yas deformation, uas muaj cov nyhuv ntawm refining cov nplej, yog li nws yog feem ntau siv nyob rau hauv lub blank manufacturing ntawm tseem ceeb qhov chaw. Casting muaj qhov xav tau ntawm cov ntaub ntawv yuav tsum tau ua. Feem ntau, cam khwb cia hlau, txhuas, thiab lwm yam muaj zoo dua casting zog. 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 khoom ntawm cov khoom txhawb nqa uas tsis tas yuav muaj cov khoom siv siab.

2.1 Siab

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

2.2 Diameter Nominal

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

2.3 Anti-kawg muaj peev xwm

Txiav txim siab los ntawm tus txheej txheem nws tus kheej, casting yog nquag tsim blowhole thaum ua. Yog li ntawd, piv nrog cov txheej txheem forging, lub peev xwm tiv thaiv ntawm cov cam khwb cia tsis zoo li ntawm forged li qub.
Yog li ntawd, hauv qee qhov kev lag luam uas muaj kev tiv thaiv kev tiv thaiv siab, xws li roj av, roj av, roj av, tshuaj lom neeg thiab lwm yam lag luam, forged steel li qub tau siv dav.

2.4 Kev tshwm sim

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

3. Qhov txawv ntawm daim ntawv thov teb

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 yog nyob ntawm qhov chaw ua haujlwm tshwj xeeb. Feem ntau hais lus, WCB li qub tsis yog kua qaub thiab alkali resistant thiab tsuas yog siv tau rau ntawm cov kav dej zoo tib yam, thaum forged steel li qub tuaj yeem tiv taus siab thiab tuaj yeem siv rau hauv qee qhov chaw ua haujlwm kub, xws li cov chaw tsim hluav taws xob thiab cov nroj tsuag tshuaj. Chav kawm valve.

4. Nqe

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