Forged steel li qub yuav ua rau tib neeg nug, yog vim li cas forged steel li qub dub? Qhov tseeb, tsis yog txhua lub forged steel li qub yog dub. Piv txwv li, stainless hlau forged steel li qub tsis yog dub.
Cov khoom tseem ceeb ntawm forged steel valve yog carbon steel, thiab carbon steel muab faib ua ob hom: 105 carbon steel; WCB cam khwb cia carbon steel; forging A105 yog qhov zoo dua li casting WCB, thiab yuav tsis muaj qhov tsis xws luag, ntau lub siab siab lossis qhov tseem ceeb yuav xaiv forging manufacturing. A105 cov khoom yuav tig dub tom qab phosphating txheej txheem, thiab nws lub luag haujlwm tseem ceeb yog tiv thaiv xeb.
Forged steel valve yog them sai sai rau lub valve lub cev dej phwj thiab xaim ntsaws siab nyem teeb meem. Tom qab qhov kev ntsuas siab ntawm lub valve, cov roj thiab dej hauv lub valve kab noj hniav ntawm lub sealing chamber yuav nce ntxiv vim qhov nce ntawm qhov kub thiab txias. Thaum txhaj cov roj, nws yog ib qho tsim nyog yuav tsum tso cov dej phwj tuaj thiab tso lub siab ua ntej, txhawm rau pab txhawb kev ua tiav ntawm cov roj txhaj tshuaj. Tom qab cov roj tau txhaj, huab cua thiab noo noo nyob rau hauv lub kaw kab noj hniav yuav tsum tau hloov tag nrho. Lub sijhawm tso tawm ntawm lub valve kab noj hniav siab tuaj yeem ua kom muaj kev nyab xeeb ntawm lub valve. Tom qab cov roj txhaj tshuaj, yuav tsum tau ceev cov dej ntws thiab cov ntsaws ruaj ruaj kom tsis txhob muaj xwm txheej. Thaum txhaj cov rog, xyuam xim rau qhov teeb meem ntawm cov rog tsis sib xws. Thaum lub sijhawm txhaj tshuaj roj ib txwm, cov roj tso tawm qhov ze tshaj plaws rau qhov chaw nres nkoj roj yuav tso cov roj ua ntej, tom qab ntawd mus rau qhov chaw qis, thiab thaum kawg mus rau qhov siab, thiab cov roj yuav tawm ib los ntawm ib qho. Yog tias nws tsis ua raws li cov cai lossis tsis muaj rog, nws ua pov thawj tias muaj qhov thaiv, thiab nws yuav tsum tau ntxuav kom huv si raws sijhawm.
