API 602 flanged gate li qub yog lub rooj vag li qub nrog flange kev sib txuas, uas yog hom kev sib txuas ntau tshaj plaws. Flanged gate li qub yog qhov ruaj khov thiab txhim khu kev qha thaum siv hauv cov kav dej, ua rau lawv zoo tagnrho rau cov ntawv thov siab. Qhov qhib thiab kaw mechanism ntawm flanged lub rooj vag valve muaj lub rooj vag uas txav mus rau qhov kev taw qhia dej. Lub rooj vag li qub tsuas tuaj yeem qhib tag nrho lossis kaw tag nrho thiab tsis tsim nyog rau kev tswj hwm lossis kev kaw. Lub rooj vag nta ob qhov chaw sib khi, feem ntau tsim cov duab kos, nrog lub kaum sab xis sib txawv raws li qhov tshwj xeeb valve, feem ntau nyob ib ncig ntawm 50 degrees. Qhov kev tsim no haum rau nruab nrab nrog qhov nruab nrab kub txog 252 degrees Fahrenheit.

API 602 forged steel valve
Qhov sib txawv ntawm Forged Steel Gate Valve thiab Cast Steel Gate Valve:
Qhov zoo ntawm forged steel rooj vag li qub yog superior rau cov cam khwb cia steel rooj vag li qub. Lawv tuaj yeem tiv taus qhov cuam tshuam loj, thiab lawv cov khoom siv kho tshuab xws li plasticity thiab toughness kuj siab dua piv rau cov hlau cam khwb cia. Txawm li cas los xij, lawv txoj kab uas hla nominal me me, feem ntau hauv qab DN50.
Cam khwb cia steel rooj vag li qub muaj qhov ntsuas qhov siab qis, feem ntau siv nrog cov nominal siab xws li PN16, PN25, PN40, thiab 150LB-900LB. Forged steel rooj vag li qub muaj qhov ntsuas siab dua: PN100, PN160, PN320, 1500LB-3500LB, thiab lwm yam.
Cam khwb cia hlau yog tsuas yog siv rau kev tsim khoom nrog cov duab nyuaj uas nyuaj rau forge los yog xav tau lub zog siab thiab plasticity. Casting muaj kua molding, whereas forging yog ib tug yas deformation txheej txheem. Forged Cheebtsam tau txais txiaj ntsig los ntawm kev txhim kho cov qauv sab hauv, cov khoom siv kho tshuab zoo dua, thiab cov qauv zoo li qub. Cov khoom tseem ceeb feem ntau xav tau forging vim cov txiaj ntsig zoo, vim tias casting tuaj yeem ua rau cov ntaub so ntswg sib cais thiab cov qauv tsis xws luag. Txawm li cas los xij, casting tseem muaj txiaj ntsig zoo rau molding complex duab qhov twg forging yog impractical los yog tsis raug nqi.
