Dab tsi yog qhov cam steel valve?
1. Cov ntsiab lus tseem ceeb
Cam khwb cia steel valve yog cov hlau (xws li WCA, WCB, WCB, cov roj av, roj av, cov roj ntsha txiav, cov cai lossis faib cov haujlwm.
2. Cov yam ntxwv tseem ceeb
Muaj feem xyuam Kub: Pa ya cam khwb cia steel valve muaj kev ua haujlwm {}}}, ib yam ntaub ntawv (xws li 16mn, 30mn) tuaj yeem txuas tau rau 595 degree. Qhov kub thiab txias yog -29 degree ~ 425 degree.
Lub peev xwm muaj peev xwm: Nominal siab Pn tsawg dua los yog sib npaug rau 40mpa, haum rau cov tshuab hluav taws xob siab raj.
Kev faib tawm thiab cov khoom lag luam raug
1. Kev sib cais raws li valve yam
| Ntaus | yam zoo |
|---|---|
| Cam khwb cia hlau Valve | Ntsug txav ntawm lub rooj vag phaj kom ua tiav kev cuam tshuam ntawm kev ntws, haum rau cov cai tswj kav thiab nruab nrab txiav-tawm. |
| CUAB HLAU POB VALVE | Pob sib hloov los tswj hwm qhov kev ntws ntawm kev tshaj tawm, xws li V-puab pob pob Core) tuaj yeem ua media uas muaj fibers, khoom me me. |
| Npuag Steel Npauj Npaim Valve | NPAUJ NPAIM PHAJ MAS MAS MAS MOTAB |
| Cam khwb cia hlau pab Valve Valve | Kev tswj hwm nruab nrab siab thiab kub, kom sawv khov sab nraud thiab feem ntau siv hauv cov tshuab pneumatic. |
2. Cov lus qhia los ntawm kev sib txuas
Flange kev txuas: xws li q41h {1}} c cam cam cam cam khwb cia steel pob valve.
Threaded kev sib txuas: xws li z11f -10 c cam cam cam cam cam cam cam cam khwb cia steel Rooj vag Valve.
Clamp Txuas: Xws li d373W -20 c cam kas nrib hlau Npauj Npaim Valve.
Cov Khoom Siv thiab Qauv Tseeb
1. Cov Khoom Siv Uas Siv
Carbon Steel Series: WCA, WCB, WCB, General-General-General Cast Steel cov ntaub ntawv.
Alloy Steel Series: 16mn, 30mn, txhawm rau txhim kho cov kev ua haujlwm kub siab.
2. Execution Txuj Ci
ASTM A216: Kev tso pa khawm hlau valve cov qauv.
ASTM A105: Ib feem ntawm cov hlau zoo (xws li 20, 25, 30 steel) siv qauv.
Daim Ntawv Thov Qhia Txog Cov Lus Qhia thiab Xaiv Cov Lus Qhia
1. Raug Industomios
Kev Tiv Thaiv Lub Zog: Roj, Nkev Pipeline System Txiav-Tawm thiab Cov Cai.
Tshuaj Txheej Txheem: Kev tswj cov kua ntawm cov xov xwm corrosive (yuav tsum tau phim cov ntaub ntawv foob, xws li PTFE hauv ob sab phle).
Thermal System: Nruab Nrab thiab cov dej sov siab, cua sov hloov cov roj ncig.
2. Xaiv cov qauv siv
Qib siab: Qhov Tseem Ceeb Sib Raug Tsim Kho Siab (xws li PN16, PN40).
Yuav tsum tau sealing:
Hard Foob: Particle puas tsis kam (xws li V-pob valve).
Mos foob: kev sib khi siab (xws li Ceal PTFE)
